Background of the Study: The increase in the therapeutic use of tramadol in the management of moderate to severe pains in some disease conditions and its unregulated access has led to its associated toxicity and there is little or no information on the protection against its associated toxicity. Aim of the Study: Considering the medicinal value of pumpkin seed oil, its availability, and neglected use, it becomes necessary to evaluate the possible potential of the seed oil in tramadol-induced oxidative stress in Wister Albino rats. Methods of the Study: This study used fifty-six (56) albino rats to determine the impact of Cucurbita pepo seed oil (CPSO) on tramadol-induced oxidative stress. The rats were grouped into 7. After a week of acclimatization, rats in group 1 (normal control) had access to water and food, while rats in group 2 received 5 mL/Kg (b.w) of normal saline. 100 mg/kg of tramadol (TM) was delivered to groups 3–6 to induce toxicity. The third group (TM control) received no treatment, whilst the other 3 groups (TM-CPSO treatment groups) received 5, 2.5, and 1.5 mL/Kg of CPSO, respectively. Group 7 received only 5 mL/kg CPSO (CPSO group). Similarly, groups 2 through 7 had unrestricted access to food and water for 42 days and received treatments via oral intubation once per day. Indicators of oxidative stress were discovered in the brain homogenate. Results: TM toxicity was demonstrated by a considerable increase (P <.05) in the brain MDA level and a significant drop (P <.05) in the brain GSH level, as well as a significant reduction (P <.05) in GPx, catalase, SOD, GST, and quinone reductase activities. Conclusion: The dose-dependent delivery of CPSO was able to restore not only the activity but also the concentrations of the altered markers. [ABSTRACT FROM AUTHOR]

The study was designed to determine the ameliorative potential of quercetin and catechin against the toxicity induced by co-exposure to Mancozeb (MZ) and arsenic in Wistar rats. Sixty-adult male Wistar rats were randomly divided into 10 groups (n=6). Group I served as control and group II was exposed to MZ [800 mg/kg, PO (per OS)]. Groups III, IV, and V were given drinking water containing sodium arsenite at the rate of 10, 50, and 100 ppb, respectively, for 28 days. Groups VI, VII, and VIII were treated with sodium arsenite in drinking water at 10, 50, and 100 ppb, respectively, along with MZ (800 mg/kg) for 28 days. Groups IX and X were given drinking water mixed with sodium arsenite at 100 ppb, MZ at 800 mg/kg, and quercetin (50 mg/kg) and catechin (50 mg/kg), respectively. Co-exposure to the toxicants (MZ and arsenic) significantly (P

Several studies revealed that different parts of Azadirachta indica A. Juss, has therapeutic potential against inflammatory issues and dyslipidemia which is a major contributing cause to cardiovascular diseases, oxidative stress and serum glucose levels, etc. Present study was conducted to evaluate anti-dyslipidemic capacity of Azadirachta indica leaf extract in dyslipidemic rabbits. Ethanolic extract of Azadirachta indica leaves was obtained by using Soxhlet apparatus. This extract was used for efficacy study on rabbits. In this context, 25 healthy rabbits were selected for study, Efficacy trial involved five groups of rabbits, 5 rabbits in each group; NC (Negative Control); healthy rabbits received normal diet. In remaining 20 rabbits, dyslipidemia was induced by using high fat diet for 28 days followed by administration of Azadirachta indica leaf ethanolic extract for 60 days in a dose-dependent manner. PC (Positive Control) include dyslipidemic rabbits received normal diet while G 1 , G 2 , G 3 groups included dyslipidemic rabbits receiving different concentrations of Azadirachta indica leaf extract (i.e. 300, 500 and 700 mg/kg of body weight, respectively). Blood samples were analyzed for serum lipid profile after every 15 days to determine the effect of treatments. Significant reduction in total cholesterol (60 ± 3.4 mg/dL), triglycerides (40.31 ± 2.5 mg/dL) and low-density lipoprotein (28.87 ± 2.1 mg/dL) was observed in G 2 (P ≤ 0.05)while a significant increase was observed in high-density lipoprotein (60.47 ± 1.7 mg/dL) of G 2 (P ≤ 0.05) as compared to other groups. Results revealed that ethanolic extract of Azadirachta indica leaves in G 2 group (@ 500 mg/kg of body weight) normalized lipid profile in dyslipidemic rabbits after 60 days of extract administration which significantly lowered TC, TG, LDL levels (P ≤ 0.05) and improved HDL level.
