Objective: This retrospective observational study analyzes the bacteriological profile of pathogens causing burn wound infections in a tertiary care center., Materials and Methods: This study was conducted at Father Muller Medical College Hospital, Karnataka, India, from January 2014 through December 2016. The specimens (ie, pus or a wound swab) were collected from patients with suspected of infection and processed as per standard microbiological techniques. The antibiotic sensitivity testing was performed by the Kirby Bauer's disk diffusion test on Mueller-Hinton agar as per Clinical and Laboratory Standards Institute guidelines., Results: During the study period, a total of 124 eligible patient samples were collected; 22 samples were excluded as there was no significant growth/colonization. Among the 102 patients included in the study, 56 (54.9%) were females and the majority (33, 32.35%) of the patients were between 18 to 30 years. Acinetobacter species and Pseudomonas aeruginosa (26.56% each) were the most common pathogen among gram-negative bacteria and Staphylococcus aureus (36, 11.25%) was the most common gram-positive bacteria. Methicillin resistance was 30.5% among the Staphylococcus aureus isolates. Most of Acinetobacter species isolates were resistant to piperacillin tazobactum (84.71%), meropenem (80%), and amikacin (87.06%). Other gram-negative bacteria were also emerging with multidrug resistance., Conclusions: The current study revealed the non-fermenting Gram-negative bacteria as the leading cause of burn wound infection and are highly resistant to available high-level antibacterial agents.

Background: In elderly people, the body's metabolic processes are not optimal and pharmacokinetics and pharmacodynamic profile of drugs are compromised or reduced. Under these conditions, the concomitant use of diverse classes of drugs can potentially increase the risk of adverse reactions and drug interactions. This will consequentially affect the already debilitated organ system. As far as the authors are aware, there are no studies addressing the drug-drug interactions and adverse drug reactions due to polypharmacy in older patients with cancer and therefore, we conducted this study., Methods: This was an observational chart-based study and was carried out in a tertiary care cancer hospital. The data concerning prescription of all prescribed medications were noted down from the medication chart of the patient in the wards., Results: The most common drug-to-drug interaction that could have happened was due to the combination of theophylline with budesonide (26.10%). Adverse drug reactions were noted during the course of time, the most common being nausea and vomiting (71.9%)., Conclusions: As the geriatric population is increasing, the need to address medical problems among aged patients with cancer is the need of the hour. The adverse drug reactions and drug interactions that have occurred were lesser when compared to published observations., Competing Interests: None

Purpose  Development of cancer chemotherapy treatment-induced hyperglycemia/ diabetes (secondary diabetes) is a major problem and has never been reported from India. The present study was planned to ascertain this in women undergoing curative chemotherapy for their breast cancer. Materials and Methods  This was a retrospective chart-based study and was conducted in a cancer specialty hospital. The information on women who were nondiabetic at the start of the treatment was collected from the files. Details on cancer diagnosis, domicile, body mass index (BMI), type of diet, marital status, number of children, and previous history of diabetes if any were considered. The blood glucose levels before surgery and after the completion of radiotherapy were considered. World Health Organization (WHO) guidelines for diabetes were considered. The data were subjected to frequency and percentage and analyzed using Chi-square test. Association between the demographic details and development of Hyperglycemia or secondary diabetes or prediabetes was done using the Pearson's correlation analysis. p < 0.05 was considered as statistically significant. Results  A total of 474 cases were included in accordance with the inclusion criteria. The results indicated that by the end of the radiation treatment, 24.89% were prediabetic, 10.97% were diabetic after being in prediabetic stage, 8.22% became diabetic without going through a prediabetic stage, and that 55.91% did not develop either prediabetic or diabetic condition. Analysis of development of secondary diabetes and prediabetes with BMI ( p < 0.0001) and age ( p < 0.024) showed a strong correlation and was significant. Conclusion  To the best of the authors' knowledge, this is the first study from India, and the results indicate that the development of secondary diabetes in women undergoing curative chemotherapy is high. Attempts are underway to ascertain the cause for the development and how it can be mitigated., Competing Interests: Conflict of Interest None declared., (MedIntel Services Pvt Ltd.

Introduction: Tiger dancing or Hulivesha, where the volunteers paint their bare body like a tiger and dance in a ritual during the Navarathri festival in Mangalore, India. There are no scientific studies done with the Hulivesha dancers at all, and therefore, we investigated the adverse effects of painting body like a tiger and dancing in the volunteers., Objective/aim: In this study, we investigated the clinico-haematological effects of topical application of lead-containing paint and dancing for three consecutive days in these dancers to ascertain the toxic effects of whole body painting and dancing., Materials and Methods: This was a case-control study and was conducted during the Dasara festival in 2013 in the Huliveshadaris (study group) and the accompanying drummers (controls). Clinical, dermatological, and musculoskeletal examination were done before (day 0) and after the three days of the function (day 3). Blood was also collected and examined for alterations in the hematological parameters, lead, antioxidant glutathione, and lipid peroxidation levels., Results: The results indicated that the all Hulivesha volunteers had severe musculoskeletal pain, while few also complained of skin reactions (61.6%), headache (25%) and nausea, and vomiting (18.75%). The results also indicated that topical application increased the levels of blood lead, caused a change in the haematological profile, decreased glutathione and increased lipid peroxidation (p < 0.03-0.0001)., Conclusions: The results from this study clearly shows that topical application of the acrylic paint increases lead, changes haematological parameters and imparts adverse skin reactions.

Purpose: Drug wastage is a major concern in oncology where costs of antineoplastic drugs are exorbitant, and the disposal of toxic drugs increases the chances of occupational hazards to healthcare and sanitary workers and environmental pollution at the site of disposal. The principal objective of this study was to ascertain the extent of drug wastage and calculate its financial costs., Materials and Methods: This was a prospective pilot study conducted to ascertain the quantity of drug wastage in a tertiary care hospital. This pilot study was conducted in day care and inpatient facilities in February 2016. The prescription of cytotoxic drugs, recommended dose, the quantity used, and remainder (waste) left were recorded from the nurses and pharmacy files of the hospital. Cost evaluation of the actual use and the waste was undertaken and an audit was conducted to understand in which anticancer drug the maximum wastage was generated., Results: The results of this study indicated that 6.1% of the total amount of reconstituted drugs was wasted. The highest drug wastage was observed in trastuzumab (29.55%), followed by etoposide (20.4%), dacarbazine (17.14%), daunorubicin (16.67%), and carboplatin (11.29%). Cost analysis showed that the total cost of the drug issued during the study period was Rs. 1,294,975 and the cost of drug wastage amounted to Rs. 143,820 (11.1%)., Conclusion: To the best of authors' knowledge, this is the first study from India and the results indicate that the financial impact of anticancer drug wastage was substantial. Attempts should be directed at minimizing the wastage and cost savings without risking patients' treatment regimen and administering effective dose schedule., Competing Interests: None

Background: Honey is a natural product made from the nectar of flowers by honey bees and has over 200 compounds in it, including sugars, water, organic acids, minerals and polyphenols - the exact structure and composition of honey often determined by which plant source(s) the honey bee took the nectar from. Honey has been used in diets and medicines for thousands of years; however, this review, for the first time, aims to look at its place in modern medicine concerning oral health., Highlight: The present review for the first time attempted to address the protective effect of honey in the oral care., Conclusion: For the first time this review addresses the usefulness of honey against Streptococcus mutans infections, dental plaque and caries, gingivitis and halitosis. Honey was also useful in preventing side effects associated with treatment of cancers of the head and neck, namely, radiation induced mucositis, xerostomia and poor wound healing. This is well supported by evidence in literature and was examined in this review., (Copyright © 2018. Published by Elsevier B.V.)

Radiation-induced mucositis is a dose-limiting factor in the effective treatment of head and neck (H & N) cancers. The objective of this study was to understand the efficacy of honey in mitigating radiation-induced mucositis and whether it would interfere with tumor control. This was a single-blinded, randomized, controlled study and was carried out in patients with H & N cancer requiring curative radiotherapy (>62 Gy (Gray)). The patients meeting the inclusion criteria were randomly assigned to receive either honey ( n = 25) or povidone-iodine (active comparator) ( n = 25) during radiotherapy. Oral mucositis was assessed using the RTOG (Radiation Therapy Oncology Group) grading system before the start, during, and at the end of the treatment by an investigator unaware of the treatment. The results indicate that when compared with the active comparator, honey reduced the radiation-induced oral mucositis, decreased the incidence of intolerable mucositis, treatment breaks, loss of treatment days ( p < 0.0001 and < 0.0003) and did not affect the radiation-induced tumor response. The clinical observations indicate that honey mitigates the radiation-induced mucositis and does not interfere with tumor cell killing., Competing Interests: This study was not funded by any external agencies and was carried out to ascertain whether honey has any protective role in preventing radiation-induced mucositis without interfering in tumor cell killing. This study was inspired from the results observed from the preliminary studies of Karadka R. Thilakchand during his short-term studentship program funded by the Indian Council of Medical Research (ICMR) in 2011, under the mentorship of Suresh Rao. The authors also declare that they do not have any financial conflicts of interest.

Background : The primary objective of this study was to ascertain the benefit of Vicco turmeric Ayurvedic cream (VTC; Vicco Laboratories, Mumbai, India) sandalwood oil and turmeric-based cream in preventing radiodermatitis in women undergoing curative radiotherapy for their breast cancer. Methods and Materials : The study was an investigator-blinded randomized study with Johnsons Baby Oil (JBO; Johnson & Johnson Ltd., Baddi, India) as a comparator, administered daily from the start of radiation therapy for 5 weeks in women receiving breast radiation therapy, 50 Gy in 2 Gy fractions daily for 5 weeks. The endpoints were to ascertain the delay in the appearance and the degree of severity of dermatitis throughout the study period in accordance to the Therapy Oncology Group (RTOG) score. Results : The results indicated that the topical application of VTC delayed and mitigated the radiodermatitis. When compared to the Johnson's Baby Oil, a significant decrease ( p = 0.025) in the incidence of grade 1 was seen at week two, and also in grade 2 and 3 at week 3 ( p = 0.003) and week 4 ( p = 0.02), respectively, in the VTC cohort. A concomitant decrease in the average severity was also observed at week 2 ( p = 0.02), week 3 ( p = 0.05) and week 4 ( p = 0.03)., Conclusions: The results indicate that VTC cream significantly reduces radiation dermatitis when applied to the breast during and after radiation therapy. The result of this study indicates the beneficial effects. Double blind randomized control studies are required to further confirm the beneficial effects of VTC in mitigating radiodermatitis is people undergoing radiation treatment for their cancer., Competing Interests: The authors declare no conflict of interest.

Background: This study was planned to evaluate the efficacy of topical application of an Aloe vera -based cream (AVC) for the prevention of ionizing radiation (X ray)-induced dermatitis in head and neck cancer patients requiring therapeutic radiation treatment (>62 Gy). Methods: From July 2012 to December 2012, a total of 60 head and neck cancer patients requiring curative radiotherapy (RT) of more than 66 Gy were prospectively enrolled and treated with AVC or a comparator Johnson's Baby Oil (JBO). Acute skin reaction was monitored and classified according to the Radiation Therapy Oncology Group (RTOG) four-point rating scale on a weekly basis. Results: The results indicate that there was a statistically significant delay in the incidence ( p = 0.04) of dermatitis at week three in the AVC application group. Application of AVC reduced the incidence of Grade 1, 2, and 3 dermatitis at subsequent time points, while Grade 4 dermatitis was not seen in either cohort. The other most important observation was that the continued application of AVC two weeks after the completion of RT was effective in reducing the average grade of dermatitis and was statistically significant ( p < 0.02). Conclusions : Prophylactic use of an AVC-based cream is thus effective in delaying radiation dermatitis in head and neck cancer., Competing Interests: The authors declare no conflict of interest.

Introduction: Diabetic Retinopathy (DR) is a well-known consequence of long standing and poorly controlled Diabetes Mellitus (DM). Several studies have demonstrated both a qualitative and quantitative reduction in health related quality of life in persons with DR. But no such study has been done in the Indian population., Aim: To assess health related and vision related quality of life in people with DR., Materials and Methods: The present study included two groups of patients with Type 1 and Type 2 diabetes. Cases included 97 patients with DR. The control group (n=26) consisted of diabetic cases with no clinically detectable DR changes. After taking informed consent, health and vision related quality of life was assessed using National Eye Institute 25-Item Visual Function Questionnaire (NEI-VFQ-25). Demographic information, social history and diabetic history were also obtained from all patients. DR was graded using the Early Treatment Diabetic Retinopathy Study (ETDRS) classification., Results: Of the 97 cases with DR, 42.3% were females. Of the 26 controls, 53.8% were females. The mean±SD age in years of the cases was 55.09±9.56 and controls were 54.12±13.01. The mean±SD of DM in years for the cases was 10.98±5.62 and for controls was 6.69±2.29. There were statistically significant (p<0.001) lower VFQ-25 composite and sub scale scores of the cases when compared with controls. As the grade of DR increased, VFQ-25 sub-scale scores decreased and this was statistically significant for composite and all sub scales (p<0.005) except ocular pain. Mann-Whitney test Z-value was highest in general health, general vision, composite score and mental health., Conclusion: Quality of life was significantly lower in diabetics with DR when compared with those without DR with maximum effect seen on general health, general vision and mental health. Quality of life decreased as the duration of retinopathy and severity of retinopathy increased.

Background: The 3 fluoroquinolone (FQ) antibiotics - ciprofoxacin, levofoxacin, and moxifoxacin - are commonly administered to oncology patients. Although these oral antibiotics are approved by the US Food and Drug Administration (FDA) for treatment of urinary tract infections, acute bacterial sinusitis, or bacterial infection in patients with chronic obstructive pulmonary disease, they are commonly prescribed off-label to neutropenic cancer patients for the prevention and treatment of infections associated with febrile neutropenia. New serious FQ-associated safety concerns have been identified through novel collaborations between FQ-treated persons who have developed long-term neuropsychiatric (NP) toxicity, pharmacovigilance experts, and basic scientists., Objective: To conduct basic science and clinical investigations of a newly identified adverse drug reaction, termed FQ-associated disability., Methods: 5 groups of C57BL/6 mice receiving the antibiotic ciprofoxacin in 10-mg increments (10 mg/kg-50 mg/kg) and 1 group of control mice were evaluated. The Southern Network on Adverse Reactions (SONAR) and a social network of FQ-treated persons with long-term NP toxicity (the Floxed Network) conducted a web-based survey. The clinical toxicity manifestations reported by 94 respondents to the web-based survey of persons who had received 1 or more doses of an FQ prescribed for any indication (generally at FDA-approved dosages) and who subsequently experienced possible adverse drug reactions were compared with adverse event information included on the product label for levofoxacin and with FQ-associated adverse events reported to the FDA's MedWatch program., Results: Mice treated with ciprofoxacin had lower grip strengths, reduced balance, and depressive behavior compared with the controls. For the survey, 93 of 94 respondents reported FQ-associated events including anxiety, depression, insomnia, panic attacks, clouded thinking, depersonalization, suicidal thoughts, psychosis, nightmares, and impaired memory beginning within days of FQ initiation or days to months of FQ discontinuation. The FDA Adverse Event Reporting System (FAERS) included 210,705 adverse events and 2,991 fatalities for FQs. Levofoxacin and ciprofoxacin toxicities were neurologic (30% and 26%, respectively), tendon damage (8% and 6%), and psychiatric (10% and 2%). In 2013, an FDA safety review reported that FQs affect mammalian topoisomerase II, especially in mitochondria. In 2013 and 2014, SONAR fled citizen petitions requesting black box revisions identifying neuropsychiatric toxicities and mitochrondrial toxicity as serious levofoxacin-associated adverse drug reactions. In 2015, FDA advisors recommended that FQ product labels be revised to include information about this newly identified disability syndrome termed "FQ-associated disability" (FQAD)., Limitations: Basic science studies evaluated NP toxicity for only 1 FQ, ciprofoxacin., Conclusion: Pharmacovigilance investigators, a social network, and basic scientists can collaborate on pharmacovigilance investigations. Revised product labels describing a new serious adverse drug reaction, levofoxacin-associated long-term disability, as recommended by an FDA advisory committee, are advised., (©2016 Frontline Medical Communications.)

The use of compounds which can selectively protect normal tissues against radiation injury is of immense use because in addition to it protecting the normal tissue, will also permits use of higher doses of radiation to obtain better cancer control and possible cure. However, most of the radio protective compounds investigated possess inadequate clinical application principally due to their inherent systemic toxicity at their optimal protective concentrations. Plants commonly used as medicinal and dietary agents have recently been the focus of attention and studies have shown that Ocimum sanctum Linn. commonly known as the Holy Basil and its water soluble flavonoids, orientin and vicenin protects experimental animals against the radiation-induced sickness and mortality at nontoxic concentrations. Studies with tumor bearing mice have also shown that both Tulsi extract and its flavonoids selectively protect the normal tissues against the tumoricidal effects of radiation. Preclinical studies have also shown that the aqueous extract of the Tulsi leaves; its flavanoids orientin and vicenin, and eugenol, the principal nonpolar constituent present in Tulsi prevent radiation-induced clastogenesis. Mechanistic studies have indicated that free radical scavenging, antioxidant, metal chelating and anti-inflammatory effects may contribute toward the observed protection. In addition, clinical studies with a small number of patients have shown that Tulsi was effective as a radio protective agent. This review summarizes the results related to the radio protective properties of Tulsi and its phytochemicals and also emphasizes the aspects that warrant future research to establish its use as a radio protective agent.

Background: Acute ulcerative colitis is an inflammation-driven condition of the bowel. It hampers the general homeostasis of gut, resulting in decreased mucus production and epithelial cell renewal. Adiponectin (APN), an adipocytokine, is secreted by the adipose tissue and has been debated both as a pro-inflammatory or anti-inflammatory protein depending on the disease condition and microenvironment. The present study delineates the role of APN depletion in mucus modulation in a model of acute colitis., Methods: APNKO and C57BL/6 (WT) male mice were given 2% DSS ad libidum for 5 days in drinking water, followed by normal drinking water for the next 5 days. Hematoxyline-eosin and Alcian Blue staining was used to observe the general colonic morphology and goblet cell quantification respectively. Protein expression levels were quantified by Western blot for MATH1, Hes1, MUC2 and MUC4. ELISA was used to study the levels of TNF-α, IL-6 and IL-1β., Results: APNKO mice showed significantly higher goblet to epithelial cell ratios, lower pro-inflammatory cytokines and higher MUC2 levels as compared to the WT mice. The protein expression levels for the mucin MUC2 supported the histopathological findings. An increase in colon tissue-secreted levels of pro-inflammatory with a reduction in anti-inflammatory cytokines in presence of APN support the pro-inflammatory role of APN during acute inflammation., Conclusion: Absence of APN is protective against DSS-induced acute colonic inflammation by means of reducing colon tissue-secreted pro-inflammatory cytokines, modulating goblet and epithelial cell expressions, and increasing the levels of secretory mucin MUC2.

Introduction: The present study aimed to assess the levels of salivary enzymes, protein and oxidant-antioxidant system in young college-going cell phone users., Materials and Methods: The cell users (students) were categorized in to two groups - less mobile users and high mobile users, based on the duration and frequency of cell use. Unstimulated whole saliva samples of the volunteers were analysed for amylase, lactate dehydrogenase (LDH), malondialdehdye (MDA) and glutathione (GSH)., Results: High mobile users had significantly higher levels of amylase (p = 0.001), LDH (p = 0.002) and MDA (p = 0.002) in saliva, when compared to less mobile users. The marginal decrease in salivary total proteins, GSH and flow rate were statistically not significant (p >0.05)., Conclusion: Significant changes in salivary enzymes and MDA suggest adverse effect of high use of cell phones on cell health.

Dengue is one of the arthropod-borne (arbo) viral diseases transmitted by female mosquito Aedes aegypti. Dengue fever has a wide spectrum of clinical presentation ranging from flu-like illness to severe complicated stage of dengue hemorrhagic fever leading to mortality. This was a retrospective study conducted in a tertiary care hospital in Coastal Karnataka, South India, to know the correlation between the clinical presentation and haematological parameters in the paediatric cases presented with dengue symptoms. A total of 163 paediatric cases who presented fever and dengue-like illness were included in the study. Of which, 69 were confirmed dengue patients. Critical analysis showed that there was a significant difference in the haematological parameters like total leucocyte count, percent differential leucocyte count, and platelets count, in the erythrocyte sedimentation rate (P < 0.05 to 0.0001). Additionally, when compared to nondengue patients, even the liver function and renal function parameters were significantly deranged (P < 0.05 to 0.0001). Stratification based on NS1, IgG, and IgM showed significant alterations in the haematological, hepatic, and renal parameters. With respect to the treatment a small percentage of patients, that is, 8% (4 patients), required platelet transfusion as their counts went below 20,000/μL. Two patients succumbed to their illness while three required ICU stay.

Inflammatory bowel diseases (IBDs), consisting mainly of ulcerative colitis (UC) and Crohn's disease (CD), are important immune-mediated diseases of the gastrointestinal tract. The etiology of the disease includes environmental and genetic factors. Its management presents a constant challenge for gastroenterologists and conventional surgeon. 5-Amninosalicylates, antibiotics, steroids, and immune modulators have been used to reduce the symptoms and for maintenance of remission. Unfortunately, long-term usage of these agents has been found to lead to severe toxicities, which are deterrent to the users. Pre-clinical studies carried out in the recent past have shown that certain dietary agents, spices, oils, and dietary phytochemicals that are consumed regularly possess beneficial effects in preventing/ameliorating UC. For the first time, this review addresses the use of these dietary agents and spices in the treatment and prevention of IBD and also emphasizes on the mechanisms responsible for their effects.

Since antiquity, Piper betel. Linn, commonly known as betel vine, has been used as a religious, recreational and medicinal plant in Southeast Asia. The leaves, which are the most commonly used plant part, are pungent with aromatic flavor and are widely consumed as a mouth freshener. It is carminative, stimulant, astringent and is effective against parasitic worms. Experimental studies have shown that it possess diverse biological and pharmacological effects, which includes antibacterial, antifungal, larvicidal, antiprotozal, anticaries, gastroprotective effects, free radical scavenging, antioxidant, anti-inflammatory hepatoprotective, immunomodulatory, antiulcer and chemopreventive activities. The active principles hydroxychavicol, allylpyrocatechol and eugenol with their plethora of pharmacological properties may also have the potential to develop as bioactive lead molecule. In this review, an attempt is made to summarize the religious, traditional uses, phytochemical composition and experimentally validated pharmacological properties of Piper betel. Emphasis is also placed on aspects warranting detail studies for it to be of pharmaceutical/clinical use to humans.

Objective: The study objective was to assess the effectiveness of a turmeric- and sandal wood oil-containing cream [Vicco(®) turmeric cream (VTC); Vicco Laboratories, Parel, India] on radiodermatitis in patients with head and neck cancer undergoing radiotherapy., Methods: A total of 50 patients with head and neck cancer requiring >60 Gy of curative radiotherapy/chemoradiotherapy were enrolled in the study. The volunteers were randomly divided into two groups of 25 patients. Group 1 was assigned to a topical application of Johnson's(®) baby oil (Johnson & Johnson Ltd, Baddi, India) and Group 2 for VTC. Prophylactic application of the cream was initiated on Day 1 and continued every day until 2 weeks after the end of treatment. Both agents were symmetrically applied within the irradiated field five times a day, and the acute skin reactions were assessed twice weekly in accordance with the Radiation Therapy Oncology Group scores by an investigator who was unaware of the details., Results: The incidence of radiodermatitis increased with the exposure to radiation and was the highest in both groups at Week 7. However, a significant reduction in grades of dermatitis were seen in cohorts applying VTC at all time points, including 2 weeks post radiotherapy (p < 0.015 to p < 0.001). The occurrence of Grade 3 dermatitis was lower in the cohorts using VTC and was statistically significant (p < 0.01). Additionally, follow-up observations 2 weeks after the completion of radiotherapy also showed a reduced degree of radiodermatitis in cohorts applying VTC, which was significant (p = 0.015)., Conclusion: VTC is shown to be effective in preventing radiodermatitis and needs to be validated in larger double-blind trials., Advances in Knowledge: For the first time, this study shows that the turmeric- and sandal oil-based cream was effective in preventing radiation-induced dermatitis.

Purpose: Radiation-induced oral mucositis is an acute morbidity seen in patients undergoing treatment for head and neck cancers. In this study, we evaluated the efficacy of turmeric in preventing radiation-induced mucositis., Methods: This was a single-blinded, randomized, controlled clinical trial and was conducted with head and neck cancer patients requiring 70 Gy of radiation or chemoradiotherapy (daily radiotherapy plus carboplatin once a week). Eligible patients (n = 80) were randomly assigned to receive either turmeric gargle (n = 40) or povidone-iodine ([n = 40] active comparator condition) during chemo/radiotherapy during the period of treatment. Oral mucositis was assessed using the RTOG (Radiation Therapy Oncology Group) grading system before the start, during, and at the end of the treatment by an investigator unaware of the treatment. The primary endpoint of this study was the incidence of mucositis every week during the 7-week period. The secondary endpoint was the effect of turmeric gargle on the incidence of treatment breaks, loss of scheduled treatment days, and decrease in body weight at the end of the treatment., Results: This study clearly suggests that when compared with the cohorts using povidone-iodine gargle, the group using turmeric as a mouthwash had delayed and reduced the levels of radiation-induced oral mucositis and was statistically significant at all time points (P< 0.001 toP< 0.0001). Additionally, the cohorts using turmeric had decreased intolerable mucositis (P< 0.001) and lesser incidence of treatment breaks in the first half of the treatment schedule before 4 weeks (P< 0.01) and reduced change in body weight (P< 0.001)., Conclusions: Gargling with turmeric by head and neck cancer patients undergoing radiation therapy provided significant benefit by delaying and reducing the severity of mucositis. Turmeric is readily available, relatively inexpensive, and highly accepted making it useful in cancer treatment., (© The Author(s) 2013.)

Dietary constituents are shown to play an important role in the development of diabetes. Studies have shown that the fruits of Emblica officinalis Gaertn or Phyllanthus emblica Linn, colloquially known as Indian gooseberry or amla and/or some of its important constituents (including gallic acid, gallotanin, ellagic acid and corilagin), possess anti-diabetic effects through their antioxidant and free radical scavenging properties. Amla has also been reported to prevent/reduce hyperglycemia, cardiac complications, diabetic nephropathy, neuropathy, cataractogenesis and protein wasting. However, clinical trial data with human subjects are limited and preliminary. For the first time this review summarizes the anti-diabetic affects of amla and also addresses the mechanisms mediating these properties.

Viscum album, an infrequently used antihypertensive in homeopathy, is evaluated by 1-group pretest-posttest model in primary hypertension. The drug was administered for 12 weeks at a dosage of 10 drops 3 times a day. Using paired t test, a significant drop in blood pressure (P < .0001) and serum triglyceride (P < .0001) was observed in the treatment group. This dual effect of Viscum album shows promise in optimizing therapy for primary hypertension.

Background: Medical research at undergraduate level has been given poor importance in developing countries including India. Less incentives, poor resources, lack of benefits has all been the reason for curbing the research interests of the students., Objective: This research was done to understand if medical students perceived research to be important at an undergraduate level, to understand the reasons for doing research and the benefits obtained from research., Study Design: Cross sectional study., Material and Methods: Questionnaires were distributed to medical students studying in second, third, fourth and fifth years in the MBBS course at an undergraduate medical conference and a medical college. Questions were so designed to verify student's ideas on research, their research involvement and their reasons for conducting research. The answers were tabulated, data analyzed and statistics were made based on their answers., Statistical Analysis: Frequency and percentage., Results: Out of the given sample, it was seen that though only 20.9% of the students had credited publications, 81.7% of the students admitted to research being essential to understanding and changing their perception of medicine. Only 38.3% of the sample found research to be cumbersome. 24.3% of the students were involved in research purely for the purpose of acquiring knowledge, 18.3% were pursuing interest in the field and a meager 1.7% were doing research to improve their curriculum vitae. Conclusion : These results are in conformance with other studies from elsewhere that shows decreased Indian medical student's engagement in researches, compared to those from developed countries, but on par with those from the developing countries.

The use of ionizing radiation, which is the cornerstone of cancer treatment, is compromised by the radiosensitivity of normal tissues. A chemical that can give selective benefit to the normal cells against the deleterious effects of ionizing radiation has been a long-sought goal. However, most of the compounds studied have shown inadequate clinical application owing to their inherent toxicity, undesirable side effects, and high cost. Studies carried out in the past 2 decades have shown that some of the classical Indian Ayurvedic drugs (Amritaprasham, Ashwagandha Rasayana, Brahma Rasayana, Chyavanprasha, Narasimha Rasayana, and Triphala Churna) possess radioprotective effects. In the current review, an attempt is made to summarize the radioprotective observations of these Ayurvedic drugs and the mechanisms responsible for the radioprotective effects.

Liver diseases characterized by inflammation or tissue damage affect the optimal functioning and increase the morbidity and mortality of the affected individual. Liver diseases are a largely neglected health issue and recent reports indicate that they affect over 10% of the world population, with the highest burden in low and middle income countries that have minimal medical resources. To complicate matters the currently available pharmacological therapies are not optimal and when used for extended periods of time impart systemic toxicity. Diet can modify pathophysiological processes, including those of hepatotoxins, and studies have shown that some dietary constituents can afford heptoprotection. Emblica officinalis Gaertn or Phyllanthus emblica Linn, commonly known as the Indian gooseberry in English or amla in Hindi, is one of the most important medicinal and dietary plants in the Indian subcontinent. The fruits are of dietary and medicinal use and have wide applications in both traditional and folk systems of medicine. Scientific studies have shown amla to be effective in preventing/ameliorating the toxic effects of hepatotoxic agents like ethanol, paracetamol, carbon tetrachloride, heavy metals, ochratoxins, hexachlorocyclohexane, antitubercular drugs and hepatotoxicity resulting from iron overload. Amla is also reported to impart beneficial effects on liver function and to mitigate hyperlipidemia and metabolic syndrome. Amla possesses protective effects against chemical-induced hepatocarcinogenesis in animal models of study. Additionally, the phytochemicals quercetin, gallic acid, corilagin and ellagic acid are also reported to protect against the cytotoxic effects of paracetamol, microcystins, galactosamine and lipopolysaccharide. The hepatoprotective actions of amla appear to be mediated by its free radical scavenging, antioxidant, anti-inflammatory and modulation of the xenobiotic detoxification process and lipid metabolism.

Purpose: This study aims to define the role of adiponectin (APN) in preventing goblet cell apoptosis and in differentiation of epithelial cells to goblet cell lineage resulting in greater mucus production and hence greater protection from chronic inflammation-induced colon cancer (CICC)., Methods: Six- to eight-week-old male APNKO and C57BL/6 (WT) mice were randomly distributed to three treatment groups: DSS, DMH, DSS + DMH and control. Chronic inflammation was induced in DSS and DSS + DMH group by administrating 2 % DSS in drinking water for 5 days followed by 5 days of normal drinking water and this constitutes one DSS cycle. Three cycles of DSS were administered to induce chronic inflammation. Cancer was induced in both APNKO and WT mice in DMH and DSS + DMH groups by intraperitoneal injections of DMH (20 mg/kg body weight) once for DSS + DMH group and once per week for 12 weeks for DMH group. On day 129, the colon tissue was dissected for mucus thickness measurements and for genomic studies. HT29-C1.16E and Ls174T cells were used for several genomic and siRNA studies., Results: APNKO mice have more tumors and tumor area in DSS + DMH group than WT mice. APN deficiency downregulated goblet to epithelial cell ratio and enhanced the colonic mucosal erosion with reduced mucus thickness. APN increases Muc2 production with no affect on Muc1 production. APN abated goblet cell apoptosis, while APN deficiency reduced epithelial to goblet cell differentiation., Conclusion: APN may be involved in reducing the severity of CICC by preventing goblet cell apoptosis and increasing epithelial to goblet cell differentiation.

The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The rhizomes have been used since antiquity in the various traditional systems of medicine to treat arthritis, rheumatism, sprains, muscular aches, pains, sore throats, cramps, hypertension, dementia, fever, infectious diseases, catarrh, nervous diseases, gingivitis, toothache, asthma, stroke and diabetes. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, dyspepsia, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, nausea and vomiting and scientific studies have validated the ethnomedicinal uses. Ginger is also shown to be effective in preventing gastric ulcers induced by nonsteroidal anti-inflammatory drugs [NSAIDs like indomethacin, aspirin], reserpine, ethanol, stress (hypothermic and swimming), acetic acid and Helicobacter pylori-induced gastric ulcerations in laboratory animals. Various preclinical and clinical studies have also shown ginger to possess anti-emetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion on its effectiveness as a broad spectrum anti-emetic. Ginger has been shown to possess free radical scavenging, antioxidant; inhibition of lipid peroxidation and that these properties might have contributed to the observed gastroprotective effects. This review summarizes the various gastroprotective effects of ginger and also emphasizes on aspects that warranty future research to establish its activity and utility as a gastroprotective agent in humans.

Aegle marmelos, commonly known as Bael and belonging to the family Rutaceae is an important medicinal plant in the traditional Indian system of medicine, the Ayurveda. The extract prepared by boiling the bark, leaves or roots in water is useful as laxative, febrifuge, and expectorant. The extract is also useful in ophthalmia, deafness, inflammations, catarrh, diabetes, and asthmatic complaints. The fruits are used in treating diarrhea, dysentery, stomach ache, and cardiac ailments. Scientific studies have validated many of Bael's ethnomedicinal properties and its potential antimicrobial effects, hypoglycemic, astringent, antidiarrheal, antidysenteric, demulcent, analgesic, anti-inflammatory, antipyretic, wound-healing, insecticidal, and gastroprotective properties. In addition, studies have also shown that Bael and some of the Bael phytochemicals possess antineoplastic, radioprotective, chemoprotective, and chemopreventive effects, properties efficacious in the treatment and prevention of cancer. For the first time, the current review summarizes the results related to these properties and emphasizes aspects that require further investigation for Bael's safe and effective use in the near future.

Background: In spite of the tremendous progress achieved in medical sciences in the last century, the management of diabetes mellitus, a disease as old as mankind, is poor. Diabetes is currently the world's largest endocrine disorder, and estimates are that it affects almost 5% of the population. Ayurveda, the Indian traditional system of medicine, is one of the world's oldest systems to have documented the diagnosis and treatment of diabetes., Methods: Experimental studies performed in accordance with the modern medicine principles have shown that some of the medicinal plants and polyherbal preparations made using the plants used in Ayurveda are effective in preventing both hyperglycemia and its complications. Syzygium jambolanum (Syn Syzygium cumini, Eugenia cumini, Eugenia jambolana), commonly known as black plum and originally indigenous to India, is one of the important antidiabetic plants., Results: Jamun has been used in various complementary and alternative systems of medicine and, before the discovery of insulin, was a frontline antidiabetic medication even in Europe. The brew prepared by boiling the Jamun seeds in boiling water has been used in the various traditional systems of medicine in India., Conclusions: This review includes the validated antidiabetic effects of Jamun and some of its compounds. Emphasis is also placed on addressing the various mechanisms of action contributing to the pharmacological effects and the aspects that need future investigations for Jamun to be of clinical use.

Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders of the gastrointestinal tract that affect more than 3 million people worldwide, but the pathological etiology is still unknown. The overall purpose of our investigations was to elucidate the possibility of pathological causes of IBD, and therefore, we determined the difference of inflammatory cytokine profiles in adipose tissue macrophages (ATMs) and T lymphocytes (ATTs) obtained near active lesions of IBD; investigated whether the alteration in ATM activation induces genes involved in collagen formation; and evaluated the effects of fatty acid oxidation inhibitors on factors involved in inflammation and collagen production by ATMs in IBD. Adipose tissues (ATs) were collected near active lesions and also at the margin of resected segments of the bowel from IBD patients with ulcerative colitis (UC) and CD (n=14/group). Normal appearing ATs from control subjects (n=14) who had colon resection for adenocarcinoma were collected as far away from the cancer lesion as possible to rule out possible changes. Compared with inactive disease lesions, ATMs and ATTs from active lesions released more IL-6, IL-4 and IL-13. Treatments of cytokine IL-4 and/or IL-13 to ATMs reduced iNOS expression but increased Arg-I expression which were exacerbated when treated with T cell- and adipocyte-conditioned medium. However, fatty acid oxidation inhibitors prevented the effects of cytokines IL-4 and/or IL-13 on iNOS and Arg-I expressions. This study was the first to show the effect of IL-4 and IL-13 on collagen formation, through iNOS and Arg-I expressions, that was exacerbated in a condition that mimics in vivo condition of active lesions. Moreover, our study was the first to provide potential benefits of fatty acid oxidation inhibitors to ATMs on preventing collagen formation; thus, providing therapeutic implications for individuals with intestinal fibrosis and stricture lesions, although future study should be guaranteed to elucidate the underlying mechanisms., (Copyright © 2012 Elsevier Ltd.

Nausea and vomiting are physiological processes experienced by every human being at some stage of their life. They are complex protective mechanisms and the symptoms are influenced by the emetogenic response and stimuli. However, when these symptoms recur frequently, they can significantly reduce the quality of life and can also be detrimental to health. The existing antiemetic agents are ineffective against certain stimuli, are expensive, and possess side effects. Herbal medicines have been shown to be effective antiemetics, and among the various plants studied, the rhizome of Zingiber officinale, commonly known as ginger, has been used as a broad-spectrum antiemetic in the various traditional systems of medicine for over 2000 years. Various preclinical and clinical studies have shown ginger to possess antiemetic effects against different emetogenic stimuli. However, conflicting reports especially in the prevention of chemotherapy-induced nausea and vomiting and motion sickness prevent us from drawing any firm conclusion. The current review for the first time summarizes the results. An attempt is also made to address the lacunae in these published studies and emphasize aspects that need further investigations for it to be of use in clinics in the future.

The tongue is an important oral structure that affects speech, position of teeth, periodontal tissue, nutrition, swallowing, nursing, and certain social activities. Ankyloglossia (tongue tie) is a congenital anomaly characterized by an abnormally short, thick lingual frenulum which affects movement of tongue. Though the effect of ankyloglossia in general appears to be a minor condition, but a major difference exists concerning the guidelines for tongue-tie division. There are no accepted practical criteria for the management of such condition, and hence this paper aims at bringing all the compilation in examination, diagnosis, treatment, and management of tongue tie together for better clinical approach.

Ocimum sanctum L. or Ocimum tenuiflorum L, commonly known as the Holy Basil in English or Tulsi in the various Indian languages, is a important medicinal plant in the various traditional and folk systems of medicine in Southeast Asia. Scientific studies have shown it to possess antiinflammatory, analgesic, antipyretic, antidiabetic, hepatoprotective, hypolipidemic, antistress, and immunomodulatory activities. Preclinical studies have also shown that Tulsi and some of its phytochemicals eugenol, rosmarinic acid, apigenin, myretenal, luteolin, β-sitosterol, and carnosic acid prevented chemical-induced skin, liver, oral, and lung cancers and to mediate these effects by increasing the antioxidant activity, altering the gene expressions, inducing apoptosis, and inhibiting angiogenesis and metastasis. The aqueous extract of Tulsi and its flavanoids, orintin, and vicenin are shown to protect mice against γ-radiation-induced sickness and mortality and to selectively protect the normal tissues against the tumoricidal effects of radiation. The other important phytochemicals like eugenol, rosmarinic acid, apigenin, and carnosic acid are also shown to prevent radiation-induced DNA damage. This review summarizes the results related to the chemopreventive and radioprotective properties of Tulsi and also emphasizes aspects that warrant future research to establish its activity and utility in cancer prevention and treatment.

Triphala, a herbal formula composed of the three fruits of Terminalia chebula Retz. (Haritaki, Family: Combretaceae), Terminalia bellirica Roxb. (Bibhitaki, Family: Combretaceae) and Phyllanthus emblica Linn. or Emblica officinalis Gaertn. (Amalaki or the Indian gooseberry, Family: Euphorbiaceae) is considered to be a universal panacea in the traditional Indian system of medicine the Ayurveda. It has been described in the Ayurveda text as a "Rasayana' and to rejuvenat the debilitated organs. Ayurvedic physicians use Triphala for many ailments but most importantly to treat various gastrointestinal disorders. Scientific studies carried out in the past two decades have validated many of the ethnomedicinal claims and researches have shown Triphala to possess free radical scavenging, antioxidant, antiinflammatory, antipyretic, analgesic, antibacterial, antimutagenic, wound healing, anticariogenic, antistress, adaptogenic, hypoglycaemic, anticancer, chemoprotective, radioprotective and chemopreventive effects. Clinical studies have also shown that Triphala was found to have good laxative property, to improve appetite and reduce gastric hyperacidity. Studies have also shown that Triphala was effective in preventing dental caries and that this effect was equal to that of chlorhexidine. The current review addresses the validated pharmacological properties of Triphala and also emphasizes on aspects that need further investigation for its future clinic application.

Inflammatory bowel disease (IBD) comprising of ulcerative colitis (UC) and Crohn's disease (CD) is a major ailment affecting the small and large bowel. In clinics, IBD is treated using 5-amninosalicylates, antibiotics, the steroids and immunomodulators. Unfortunately, the long term usages of these agents are associated with undue side effects and compromise the therapeutic advantage. Accordingly, there is a need for novel agents that are effective, acceptable and non toxic to humans. Preclinical studies in experimental animals have shown that curcumin, an active principle of the Indian spice turmeric (Curcuma longa Linn) is effective in preventing or ameliorating UC and inflammation. Over the last few decades there has been increasing interest in the possible role of curcumin in IBD and several studies with various experimental models of IBD have shown it to be effective in mediating the inhibitory effects by scavenging free radicals, increasing antioxidants, influencing multiple signaling pathways, especially the kinases (MAPK, ERK), inhibiting myeloperoxidase, COX-1, COX-2, LOX, TNF-α, IFN-γ, iNOS; inhibiting the transcription factor NF-κB. Clinical studies have also shown that co-administration of curcumin with conventional drugs was effective, to be well-tolerated and treated as a safe medication for maintaining remission, to prevent relapse and improve clinical activity index. Large randomized controlled clinical investigations are required to fully understand the potential of oral curcumin for treating IBD.

Background: Inflammatory bowel diseases are associated with increased adiponectin (APN) levels, which may exert pro-inflammatory effects in these individuals. Since habitual exercise may increase APN, the aim of this study was to determine how exercise training affects mice with acute colitis., Methods: Male adiponectin knock out (APNKO) and wild type (WT) mice (C57BL/6) were randomly assigned to 4 different groups: 1) Sedentary (SED); 2) Exercise trained (ET); 3) Sedentary with dextran sodium sulfate (DSS) treatment (SED + DSS); and 4) Exercise trained with DSS (ET + DSS). Exercise-trained mice ran at 18 m/min for 60 min, 5d/wk for 4 weeks. Subsequently, the ET + DSS and the SED + DSS mice received 2% DSS in their drinking water for 5 days (d), followed by 5d of regular water., Results: The clinical symptoms of acute colitis (diarrhea, stool haemoccult, and weight loss) were unaffected by exercise and there was no difference between the APNKO and WT mice (p > 0.05) except on day 39. However, the clinical symptoms of the DSS-treated APNKO mice were worse than WT mice treated with DSS and had increased susceptibility to intestinal inflammation due to increased local STAT3 activation, higher IL-6, TNF-α, IL-1β and IL-10 levels, and as a result had increased intestinal epithelial cell proliferation (p < 0.05). Exercise training significantly decreased pro-inflammatory cytokines including IL-6, TNF-α and IL-1β (p < 0.05) in the DSS + EX APNKO mice but had no effect on epithelial cell proliferation. Exercise was also found to significantly decrease the phosphorylation expression of STAT3 in both WT and APNKO mice in DSS + EX group when compared to DSS + SED., Conclusions: Exercise training may contribute in alleviating the symptoms of acute colitis and APN deficiency may exacerbate the intestinal inflammation in DSS-induced colitis.

Radiation is an important modality in treating people with cancer especially when surgical intervention is impracticable or might debilitate the patient. However, effective use of ionizing radiation is compromised by the side effects that result from radiation-induced damage to normal tissue. The use of radioprotective compounds, which can selectively protect normal tissues against radiation injury is of immense use because in addition to association with protecting the normal tissue, it will also permits use of higher doses of radiation to obtain better cancer control and possible cure. However, till date no ideal radioprotectors are available as most synthetic compounds are toxic at their optimal concentrations. Plants commonly used as dietary and or therapeutic agents have recently been the focus of attention since in most cases they are non-toxic and are easily accepted for human use. Ginger, the rhizomes of Zingiber officinale Roscoe (Zingiberaceae), has widely been used as both culinary and medicinal agent. Preclinical studies carried out in the last decade has shown that ginger and its phytochemicals dehydrozingerone, zingerone possess radioprotective effects in laboratory animals and in cultured cells in vitro. The hydroalcoholic extract of ginger rhizome when administered either through intraperitoneal or oral route was effective in protecting against gamma radiation-induced sickness and mortality. The phytochemicals dehydrogingerone and zingerone present in ginger are also shown to protect mice against radiation-induced sickness and mortality. Mechanistic studies have indicated that the free radical scavenging, antioxidant affects, anti-inflammatory and anti-clastogenic effects may contribute towards the observed protection. Additionally, studies with tumor bearing mice have also shown that zingerone selectively protects the normal tissues against the tumoricidal effects of radiation. This review for the first time summarizes the results related to the radioprotective properties and also emphasizes the aspects that warrant future research to establish its activity and utility as a radioprotective agent.

Despite significant advances and development of novel anti-emetics, nausea and vomiting (emesis) is a major side-effect of cancer chemotherapy. At times, severe nausea and vomiting may also lead to reduction in adherence to the treatment regimen, and this will concomitantly affect the patient's survival. The rhizome of Zingiber officinale, commonly known as ginger, is globally an important spice. It has been used for centuries in the Indian, Chinese, Arabic, Tibetan, Unani, and Siddha systems of traditional medicine to treat nausea and vomiting induced by different stimuli. Preclinical studies with experimental animals (dogs and rats) have shown that the various extracts of ginger and the ginger juice possess anti-emetic effects against chemotherapy-induced nausea and vomiting. Gingerol, the active principle, is also shown to possess anti-emetic effects in minks. However, with regard to humans, while most studies have been supportive of the preclinical observations, a few have been contradictory. The exact mechanism responsible for the anti-emetic effects of ginger is unknown; however, the ginger phytochemicals, especially 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol, may function as a 5-hydroxytryptamine (5-HT3) antagonist, NK1 antagonist, antihistaminic, and possess prokinetic effects. The present review for the first time attempts to address the anti-emetic observations and the variability in response of the anti-emetic effects of ginger in cancer chemotherapy. An attempt is also made to address the lacunae in the published studies and emphasize aspects that need further investigations for ginger to be of use in clinics as an anti-emetic agent in the future.

The use of ethnornedical information has immensely contributed to health care, and scientific studies have shown that the evaluation of traditionally used medicines may provide leads towards effective drug discovery. Since antiquity, Alstonia scholaris connmonly known as devil's tree has been used for the treatment of many human ailments. Literature suggests that Alstonia scholaris is useful in treating malaria, abdominal disorders, dyspepsia, leprosy, skin diseases, tumors, chronic and foul ulcers, asthma, bronchitis, helminthiasis, agalactia, and debility. Preclinical studies have shown that it possesses anti-microbial, anti-diarrhoeal, anti-plasmodial, anti-oxidant, anti-inflammatory hepatoprotective, nootrophic, anti-stress, anti-fertility, immunomodulatory, analgesic, anti-ulcer, wound healing, anti-cancer, chemopreventive, radiation protection, radiation sensitization, and chemosensitization activities. The diverse pharmacological observations are supposed to be due to the presence of alkaloids, flavonoids and phenolic acids. The bark and leaf extract when administered orally did not induce lethality or adverse affects at the limit doses of 2 000 mg/kg body weight. However when administered intraperitoneally at high concentrations, the extract showed systemic and developmental toxicities. This review addresses the experimentally authenticated facts and also suggests the need for research on chemical and pharmacological properties of Alstonia scholaris.

Context: Berberis aristata DC (Berberidaceae) is an important medicinal plant with claims of widespread medicinal value in indigenous medicine. It is used by herbal healers to treat oral cancers., Objective: To evaluate the antineoplastic activity of the extracts of Berberis aristata in Ehrlich ascites carcinoma (EAC)-bearing mice with cisplatin as positive control in the advanced stage of tumorigenesis., Materials and Methods: Brine shrimp lethality bioassay (BSL) of extracts and effect on the tumor cell viability in vitro were carried out. EAC was induced in Swiss albino mice by injecting 10(6) cell/mL of tumor cell suspension i.p. Antineoplastic activity of the aqueous and ethanol extracts (100 and 6.5 mg/kg i.p., respectively) was compared with that of cisplatin (3.5 mg/kg i.p.) on the parameters such as percentage increase in weight, median survival time, and hematology., Results: Ethanol extract attenuated percentage increase in weight gain (-6.86 ± 1.50) due to tumor cell proliferation and increased the survival time (19.5 days) when compared to control group (19.10 ± 2.31 and 16 days, respectively). However, the effect was less than that of cisplatin. In vitro cytotoxicity assay as well as BSL test showed the cytotoxic effect of the extracts. Cisplatin and the extracts reversed the tumor-induced alterations in total white blood cell count, differential leukocyte counts, total red blood cell count, and hemoglobin contents., Discussion and Conclusion: Of the two extracts, the ethanol extract was observed to be more efficient and the presence of alkaloids and flavonoids may be responsible for the observed anticancer effects.

Chemotherapy- and radiotherapy-induced nausea and vomiting are the most common, intractable and unpleasant side effects in patients undergoing treatment for cancer. 5-Hydroxytryptamine-3 (5-HT3) receptor antagonists plus dexamethasone have significantly improved the control of acute nausea and vomiting, but delayed nausea and vomiting remains a significant clinical problem. Combined neurokinin-1 receptor antagonists with 5-HT3 antagonists and steroids are observed to be better in the control of both acute and delayed emesis. However, the use of these antiemetics is observed to possess inherent side effects. The medicinal plants such as Scutellaria baicalensis, Korean red ginseng, American ginseng berry, Ganoderma lucidum, Zingiber officinale, grape seed extract, and the oil of Mentha spicata are reported to be effective in the treatment of nausea and vomiting mostly in preclinical studies. Of these, ginger has also been evaluated for its efficacy in humans and the results have been contradictory. The current review for the first time summarizes the results related to these properties. An attempt is also made to address the lacunae in these published studies and to emphasize aspects that need further investigations for these plants to be of use in clinics in the future.

Long term alcohol consumption is one of the important causes for liver failure and death. To complicate the existing problem there are no dependable hepatoprotective drugs and a large number of patients prefer using complementary and alternative medicines for treating and managing hepatic complications. Almost 25 centuries ago, Hippocrates, the father of medicine, proclaimed "Let food be thy medicine and medicine be thy food." Exploring the association between diet and health continues even today. Preclinical studies carried out in the recent past have shown that the commonly used dietary agents like Allium sativum (garlic), Camellia sinensis (tea), Curcuma longa (turmeric), Emblica officinalis (Indian gooseberry), Ferula asafoetida (asafoetida), Garcinia cambogia (Malabar tamarind), Glycine max (soyabean), Murraya koenigii (curry leaves), Piper betle (beetle leaf), Prunus armeniaca (apricot), Ocimum gratissimum (wild basil), Theobroma cacao (cocoa), Trigonella foenum-graecum (fenugreek) and Vitis vinifera (grapes) protect against ethanol-induced hepatotoxicity. Mechanistic studies have shown that the beneficial effects of these phytochemicals in preventing the ethanol-induced hepatotoxicity are mediated by the antioxidant, free radical scavenging, anti-inflammatory and anti-fibrotic effects. The present review for the first time collates the hepatoprotective effects of these agents and also emphasizes on aspects that need future research to establish their utility in humans.

Despite acquiring a strong understanding of the molecular basis and advances in treatment, cancer is the second major cause of death in the world. In clinics, the stagedependent treatment strategies may include surgery, radiotherapy and systemic treatments like hormonotherapy and chemotherapy, which are associated with side effects. The use of traditional herbal medicine in cancer patients is on a rise, as it is believed that these medications are non toxic and alleviate the symptoms of cancer, boost the immune system, or may tackle the cancer itself. Since antiquity the rhizome of Zingiber officinale Roscoe commonly known as ginger (family Zingiberaceae) have widely been used as a spice and condiment in different societies. Additionally, ginger also has a long history of medicinal use in various cultures for treating common colds, fever, to aid digestion, treat stomach upset, diarrhoea, nausea, rheumatic disorders, gastrointestinal complications and dizziness. Preclinical studies have also shown that ginger possesses chemopreventive and antineoplastic properties. It is also reported to be effective in ameliorating the side effects of γ-radiation and of doxorubicin and cisplatin; to inhibit the efflux of anticancer drugs by P-glycoprotein (P-gp) and to possess chemosensitizing effects in certain neoplastic cells in vitro and in vivo. The objective of this review is to address observations on the role of ginger as adjuvant to treatment modalities of cancer. Emphasis is also placed on the drawbacks and on future directions for research that will have a consequential effect on cancer treatment and cure.

The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger, is one of the most widely used spice and condiment. It is also an integral part of many traditional medicines and has been extensively used in Chinese, Ayurvedic, Tibb-Unani, Srilankan, Arabic, and African traditional medicines, since antiquity, for many unrelated human ailments including common colds, fever, sore throats, vomiting, motion sickness, gastrointestinal complications, indigestion, constipation, arthritis, rheumatism, sprains, muscular aches, pains, cramps, hypertension, dementia, fever, infectious diseases, and helminthiasis. The putative active compounds are nonvolatile pungent principles, namely gingerols, shogaols, paradols, and zingerone. These compounds are some of the extensively studied phytochemicals and account for the antioxidant, anti-inflammatory, antiemetic, and gastroprotective activities. A number of preclinical investigations with a wide variety of assay systems and carcinogens have shown that ginger and its compounds possess chemopreventive and antineoplastic effects. A number of mechanisms have been observed to be involved in the chemopreventive effects of ginger. The cancer preventive activities of ginger are supposed to be mainly due to free radical scavenging, antioxidant pathways, alteration of gene expressions, and induction of apoptosis, all of which contribute towards decrease in tumor initiation, promotion, and progression. This review provides concise information from preclinical studies with both cell culture models and relevant animal studies by focusing on the mechanisms responsible for the chemopreventive action. The conclusion describes directions for future research to establish its activity and utility as a human cancer preventive and therapeutic drug. The above-mentioned mechanisms of ginger seem to be promising for cancer prevention; however, further clinical studies are warranted to assess the efficacy and safety of ginger.

Emblica officinalis Gaertn. or Phyllanthus emblica Linn, commonly known as Indian gooseberry or amla, is arguably the most important medicinal plant in the Indian traditional system of medicine, the Ayurveda. Various parts of the plant are used to treat a range of diseases, but the most important is the fruit. The fruit is used either alone or in combination with other plants to treat many ailments such as common cold and fever; as a diuretic, laxative, liver tonic, refrigerant, stomachic, restorative, alterative, antipyretic, anti-inflammatory, hair tonic; to prevent peptic ulcer and dyspepsia, and as a digestive. Preclinical studies have shown that amla possesses antipyretic, analgesic, antitussive, antiatherogenic, adaptogenic, cardioprotective, gastroprotective, antianemia, antihypercholesterolemia, wound healing, antidiarrheal, antiatherosclerotic, hepatoprotective, nephroprotective, and neuroprotective properties. In addition, experimental studies have shown that amla and some of its phytochemicals such as gallic acid, ellagic acid, pyrogallol, some norsesquiterpenoids, corilagin, geraniin, elaeocarpusin, and prodelphinidins B1 and B2 also possess antineoplastic effects. Amla is also reported to possess radiomodulatory, chemomodulatory, chemopreventive effects, free radical scavenging, antioxidant, anti-inflammatory, antimutagenic and immunomodulatory activities, properties that are efficacious in the treatment and prevention of cancer. This review for the first time summarizes the results related to these properties and also emphasizes the aspects that warrant future research to establish its activity and utility as a cancer preventive and therapeutic drug in humans.

Background and Objectives: "In all things of nature there is something of the marvelous". In the present study the anti-hyperglycemic and anti-oxidative potential of aqueous extract of Trigonella foenum graceum (TFG), a traditional medicinal herb was assessed in liver and WBC of alloxan induced diabetic rats. Free radicals can cause oxidative damage, which is balanced by the antioxidants. This has been implicated in aging, and diseases such as diabetes and other chronic conditions., Material and Methods: TFG extract was administered orally [500 (LM) and 1000 mg/kg body weight (HM)] for six weeks. The effect of TFG on blood glucose were studied and the levels of lipid peroxidation [MDA (Malondialdehyde)] and antioxidant enzymes [SOD (Superoxide dismutase), GPx (Reduced Glutathione peroxidase)] were estimated and compared with standard drugs glibenclamide and insulin., Results: Treatment with TFG, insulin and glibenclamide resulted in significantly reduced blood glucose in LM (8.71%) and HM (3.87%) in comparison with normal controls. There was a significant decrease in lipid peroxidation in liver and white blood cells (WBC) in both low and high doses [liver LM (49%), HM (57.25%)], [WBC LM (54.28%), HM (62.5%)] and increase in antioxidant enzymes SOD [liver LM (33.59%), HM (58.7%)] [WBC LM (44.9%)] HM (58.7%) and GPx [Liver LM (58.55%), HM (40.20%)], [WBC LM (55.46%), HM (56.4%)] when compared to diabetic controls., Discussion: Potency of TFG in restoring several parameters to normal values is comparable to glibenclamide, though not as efficient as insulin, an indication of its antihyperglycemic and antioxidant effect.
