Background: Nephrotoxicity, the rapid impairment of kidney function caused by harmful drugs and chemicals, affects about 20% of cases and is projected to become a leading cause of death by reactive oxygen species (ROS). Gentamicin (GM), an aminoglycoside antibiotic is one of the well know drugs/chemicals to cause nephrotoxicity both in humans and animals. Methods: A study on the effects of a synthetic phenolic compound, called 5-a, on GM-induced nephrotoxicity in male Wistar albino rats was conducted. The rats were grouped into five groups: normal control (NC), GM control (GM), positive control (GM + Dexa), treatment I (GM + 5-a 5 mg/kg) and treatment II (GM + 5-a 10 mg/kg). Throughout the experiment, the rats' weights were monitored, and at its conclusion, their serum and kidney tissues were analyzed for renal function indicators and inflammatory markers. The study also included histopathological evaluations, molecular docking studies, blood and urine analyses for electrolyte changes, and behavioural assessments for central nervous system impact. Results: 2-{5-[(2-hydroxyethyl)-sulfanyl]-1,3,4-oxadiazol-2-yl} phenol (5-a) significantly protected against renal damage by reducing inflammatory markers, improving antioxidant defences, and decreasing kidney injury, particularly at higher doses. The findings suggest that compound 5-a, due to its anti-inflammatory and antioxidant properties, could be a promising therapeutic option for reducing gentamicin-induced nephrotoxicity and potentially for other kidney disorders in the future. Conclusion: These findings highlight the therapeutic effects of compound 5-a in alleviating gentamicin-induced nephrotoxicity. [ABSTRACT FROM AUTHOR]

Background: Bael is well-known for its antibacterial properties. Aqueous fruit extracts have also been shown to have hepatoprotective properties; the nephroprotective and hepatoprotective properties of Ethanolic extracts have not yet been tested. Objective: To evaluate the hepatoprotective and nephroprotective activities of Bael against CCl4-induced toxicity in rats. Methods: Two dosages of Bael's Ethanolic extract (100 and 200 mg/kg/day) were compared with 100 mg/kg of silymarin. Histopathologic alterations of the liver and kidney, as well as biochemical blood parameters such as bilirubin, urea, uric acid, total protein and creatinine, alkaline phosphatase (ALP), alanine aminotransferase (ALT), were examined and assessed. Results: Bael was more successful in lowering high levels of urea, creatinine, ALT, AST, and ALP when he used a 200 mg/kg/day methanol extract. According to the histopathologic assessment, Bael lessened the CCl4-induced hepatic and renal necrosis. The more significant dose resulted in reductions in AST, ALT, GGT, ALP, and bilirubin of 45,25, 52,36, and 16%, respectively. Ethanolic extract 200 mg/kg/day also shows a reduction in elevated levels of Creatinine, Urea, Uric Acid, and Total Protein by 57%, 52%, 34%, and 9%, respectively. Conclusion: There were established hepatoprotective and nephroprotective effects of the Bael fruit methanol extract, with 200 mg/kg/day being the most beneficial dose. This provides scientific proof that medicinal herbs like Bael can be used to treat renal and liver diseases.

Titanium dioxide nanoparticles (TiO2-NPs) are one of the most popular nanoscale materials and have a wide range of applications in the manufacturing industry; nonetheless, researchers' focus has been directed to the detrimental consequences of TiO2-NPs. The current study was designed to assess the potential hazardous effects of chemically synthesized TiO2-NPs on the placenta and feto-maternal kidneys of rats. On the other hand, the probable positive impact of TiO2-NPs made after green synthesis was also evaluated. HepG2 cell lines were used to assess the cytotoxicity of chemical and green TiO2-NPs. Five groups of fifty pregnant female rats were formed (n=10). The first (control) group received distilled water. The second and third groups were orally given 100 and 300 mg/kg body weight (bw) of chemical TiO2-NPs, respectively. The fourth and fifth groups were orally given 100 and 300 mg/kg bw of green synthesized TiO2-NPs, respectively. On gestational day 20 (GD 20), blood and tissues were collected for biochemical and histological studies. Our findings revealed that chemical TiO2-NPs induced apoptosis in HepG2 cells at high concentrations, while there was no observed toxicity for green TiO2-NPs. The chemically treated TiO2-NPs groups showed a significant decrease in the level of HDL and a significant increase in cholesterol, LDL-cholesterol, and triglyceride levels. Renal tissues showed necrosis with exfoliation of lining epithelial cells, degenerated tubules, and glomerulonephritis. While the placenta was atrophied and hyalinized. Moreover, Bax expression significantly increased in the renal tubular cells and the villi of the placenta. Contrariwise, green TiO2-NPs-treated groups showed a significant rise in HDL levels with a significant reduction in triglycerides and LDL levels, while cholesterol levels were unaffected. Also, renal tissues showed mild degenerative changes in the glomeruli and renal tubules; thus, noticeable regeneration of epithelium lining tubules was detected in the maternal kidney. Bax showed a minimal reaction in the renal tubules and the villi of the placenta. It concluded that in contrast to chemical TiO2-NPs, biosynthesized TiO2-NPs with garlic showed a positive impact on the biochemical profile and histological investigations. [ABSTRACT FROM AUTHOR]

Coriander is a notable medicinal plant known for its diverse properties, including anti‐inflammatory, antioxidant, anticancer, analgesic, and anti‐diabetic effects. Despite its recognized health benefits, research on its nephroprotective properties is limited. This study aimed to investigate the potential nephroprotective properties of an aqueous extract derived from coriander leaves using an aristolochic acid‐intoxicated zebrafish model. To assess kidney abnormalities induced by aristolochic acid (AA), we utilized the transgenic line Tg(wt1b:egfp), which expresses green fluorescent protein (GFP) in the kidney. Our previous report indicated that AA exposure leads to acute renal failure in zebrafish characterized by kidney malformation and impaired renal function. However, pretreatment of coriander extract (CE) can mitigate kidney malformations induced by AA. In addition, CE pretreatment reduces the accumulation of red blood cells in the glomerular region. To verify the nephroprotective effects of CE, we analyzed renal function by measuring the glomerular filtration rate in zebrafish embryos. Results indicate that CE partially mitigates renal function impairment caused by AA exposure, suggesting its potential to attenuate AA‐induced renal failure. Mechanistically, pretreatment with CE reduces the expression of proinflammatory and proapoptotic genes induced by AA. This suggests that CE likely alleviates acute renal failure by reducing inflammation and apoptosis. As a result, we regard zebrafish as a valuable model for screening natural compounds that have the potential to alleviate AA‐induced nephrotoxicity. [ABSTRACT FROM AUTHOR]

Cadmium (Cd) is one of the most abundant toxic heavy metals, and its exposure is linked to serious kidney intoxication, a major health problem. Evidence reported that inflammatory damage is a key factor in Cd renal intoxication. Perindopril (PER) is an angiotensin-converting enzyme inhibitor approved for treating hypertension and other cardiovascular problems. Significantly, RAS activation results in inflammatory damage. Our study aimed to examine the renoprotective effects of PER in Cd-induced nephrotoxicity, the impact of inflammation, and the underlying molecular mechanisms. PER was given at a dose of 1 mg/kg per day. Cd was injected at a dose of 1.2 mg/kg, as a single dose. Treatment with PER led to a significant decrease in serum levels of urea, creatinine, uric acid, and urine albumin/creatinine ratio. PER effectively mitigated inflammation by decreasing MPO, NO, IL-1β, IL-6, and INF-γ levels mediated by downregulating NF-κB expression and suppressing JAK-1 and STAT3 phosphorylation. PER modulates Ang II/Ang 1-7 axis in Cd-intoxicated rats by decreasing Ang II expression and increasing Ang-(1-7) expression. PER inhibits Cd-induced apoptosis by lowering Bax, cytochrome c, and cleaved caspase 3 expressions while increasing Bcl-2 expression. In conclusion, PER dampens Cd-induced kidney intoxication by modulating Ang II/Ang 1-7 axis, suppressing NF-κB, JAK-1/STAT3, and apoptosis signals. [ABSTRACT FROM AUTHOR]

Boerhavia diffusa L., a flowering plant is traditionally used as a therapy for protecting against several diseases. The present study aims to identify the optimal extraction conditions for ultrasound-assisted solvent extraction (USAE) for retrieving highest amount of biologically important compounds from B. diffusa L. through RSM (Response Surface Methodology) and validated by ANFIS (adaptive neuro-fuzzy inference system), and MLA (machine learning algorithm) models. Numerous extraction parameters have played a major role in the extraction process for obtaining maximum yield of bioactive compounds. The four majorly contributing independent parameters, ethanol concentration (X1: 60–70%), temperature (X2: 35–45 °C), particle size (X3: 300–500 µm), and ultrasonic-exposure time (X4: 15–20 min), and at five levels (− 2, − 1, 0, + 1, + 2) concerning dependent parameters, TPC (y1), TFC (y2), %DPPH*sc (y3), %ABTS*sc (y4) and %H2O2*sc (y5)) were chosen. The optimal extraction condition from RSM was observed at X1 = 67.5–70%, X2 = 35 °C, X3 = 300 µm and X4 = 20 min; under this situation, y1 = 312.59–316.271 mg gallic acid equivalents (GAE)/g, y2 = 138.748–142.052 mg rutin equivalents (RU)/g and their antioxidant potentials (y3 = 59.98–61.621%, y4 = 76.762–78.642%, and y5 = 64.623–62.362%) have been noted. ANFIS and MLA were used to authenticated the optimized extraction parameters of RSM. Many experimental values were well-matched with the predicted values of ANFIS and MLA. A well-fitted quadratic model was obtained. Further, GC–MS analysis performed to identify the compounds present in the optimized extract yielded 17 compounds. In silico molecular docking study was done to predict the nephroprotective effect of the compounds present in the optimized extract. [ABSTRACT FROM AUTHOR]

Background: This study aims to investigate the effect of pomegranate juice on kidney damage caused by lithium in rats. Methods: Six groups of animals were studied, group one received neither lithium nor pomegranate juice, group two received only lithium, group three received only pomegranate juice, and groups four to six received both lithium and pomegranate juice at different doses. Kidney biomarkers were investigated as indicators of acute kidney failure. Results: Comparison between the studied groups regarding the amount of creatinine in the serum of rats showed a significant relationship between serum creatinine levels of rats in the group receiving lithium and the control group, and the group receiving lithium and those receiving pomegranate juice at a dose of 100 mg/kg. A significant relationship was observed in the study of serum urea amount in rats between the control group and the group receiving lithium, and the lithium group and the group receiving pomegranate juice at a dose of 100 mg/kg. Conclusions There was no significant difference between the groups when the amount of cystatin C in the serum of rats was compared. Pomegranate juice at 100 mg/kg and lithium (25mg/kg) led to a significant decrease in serum creatinine levels, which reduced kidney damage induced by lithium. Serum urea also decreased significantly, suggesting that pomegranate has anti-toxic effects on kidneys from lithium toxicity

Doxorubicin (DOX), an anthracycline chemotherapy, plays a prominent role in the treatment of various cancers. Unfortunately, its nephrotoxic effects limit its dosing and expose cancer survivors to increased morbidity and mortality. This study examined the nephroprotective effects of eriodictyol, a natural polyphenolic flavanone, in DOX-treated rats and the molecular pathways involved. Forty adult rats were divided into five groups (8/group): Control; eriodictyol (20 mg/kg/day); DOX (2.5 mg/kg, twice/week); DOX + Eriodictyol; and DOX + Eriodictyol + Compound C (CC), an AMPK inhibitor (0.2 mg/kg/day). Experiments continued for 21 days. Eriodictyol administration in DOX-treated rats reduced their fasting glucose levels and increased food intake, final body weight, and kidney weight, improved kidney function, prevented glomerular and tubular damage, and reduced collagen deposition and renal TGF-β1 mRNA levels. Furthermore, eriodictyol reduced their renal levels of Bax, caspase-3, and cytochrome-c; and enhanced the levels of Bcl2. Noticeably, in the kidneys of both controls and DOX-treated rats, eriodictyol increased levels of phosphorylated-AMPK(Thr172) but not AMPK mRNA nor protein levels. Also, in the same two groups, eriodictyol increased mRNA and nuclear Nrf2 levels, and levels of glutathione, superoxide dismutase, catalase, and hemeoxygenase-1, but reduced the levels of malonaldehyde, TNF-α, and mRNA, total, and nuclear levels of NF-κB. All the detected nephroprotective effects and improvements in the levels of markers of oxidation and inflammation were prevented by coadministration of CC. In conclusion, the coadministration of eriodictyol and DOX alleviates DOX-induced renal damage. In renal tissues, eriodictyol is an AMPK activator and its nephroprotective antioxidant and anti-inflammatory effects are AMPK-dependent.

AbstractThe present study was designed to develop a self-micellizing solid dispersion (SMSD) containing Thymoquinone (TQM), a phytonutrient obtained from Nigella sativa seeds, aiming to improve its biopharmaceutical and nephroprotective functions. The apparent solubility of TQM in polymer solutions was used to choose an appropriate amphiphilic polymer that could be used to make an SMSD system. Based on the apparent solubility, Soluplus® was selected as an appropriate carrier, and mixing with TQM, SMSD-TQM with different loadings of TQM (5–15%) was made by solvent evaporation and freeze-drying techniques, respectively, and the formulations were optimized. The optimized SMSD-TQM was evaluated in terms of particle size distribution, morphology, release characteristics, pharmacokinetic behavior, and nephroprotective effects in a rat model of acute kidney injury. SMSD-TQM significantly improved the dissolution characteristics (97.8%) of TQM in water within 60 min. Oral administration of SMSD-TQM in rats exhibited a 4.9-fold higher systemic exposure than crystalline TQM. In a cisplatin-induced (6 mg/kg, i.p.) acute kidney-damaged rat model, oral SMSD-TQM (10 mg/kg) improved the nephroprotective effects of TQM based on the results of kidney biomarkers and histological abnormalities. These findings suggest that SMSD-TQM might be efficacious in enhancing the nephroprotective effect of TQM by overcoming biopharmaceutical limitations.

Aim: In our present research, we aimed to evaluate the protective effects of HF1, HF2, and HF3 against liver and kidney damage induced by Cisplatin in Sprague Dawley rats. The ethanol fraction of the plant underwent initial phytochemical analysis followed by subsequent in vivo screenings. The findings from the phytochemical investigation indicated that HF2 demonstrated a more potent hepatoprotective and renal protective activity. Background: Anti-cancer medications have the potential to inflict harm on the liver and kidneys, underscoring the crucial need for hepatoprotection in safeguarding liver function. Among the elderly population, liver and kidney impairment account for 10% of chronic hepatitis and renal failure cases. The decline induced by anti-cancer drugs has not been thoroughly assessed, partly due to its underestimation in clinical practice and challenges in making a precise diagnosis. While chemotherapeutic agents can induce liver toxicity through various mechanisms and lead to different types of liver and kidney injuries, they share the common trait of being both hepatotoxic and nephrotoxic. Materials and Methods: The dried peels of Aesculus indica fruits and powdered leaves of Achyranthes aspera were subjected to Soxhlet extraction using 95% ethanol. Rat will randomly into five groups (six rats per each group). cisplatin group will give a single injection of cisplatin (20 mg per Kg, i.p) on the first 1st, 7th, 14th, 21th and 28th days. Hepatic function was assessed by measuring blood bilirubin, Glutamate Oxaloacetate Transferase (SGOT), and Glutamate Pyruvate Transaminase (SGPT). Blood tests were used to check the function of the liver and kidneys. Results: These results collectively suggest that HF1, HF2, and HF3 serve as a potential reservoir of novel secondary metabolites. Moreover, this study has laid the groundwork for future research in pharmacological studies, particularly in the development of potent biomedicine for the treatment of various chronic diseases. Conclusion: The current study has also proved the way for future pharmacological investigations, particularly with regard to all medications derived from the creation of powerful medicines for the management of various chronic conditions.

AbstractNephrotoxicity is the major side effect of cisplatin, an effective platinum-based chemotherapeutic drug that is applicable in the treatment of several solid-tissue cancers. Studies have indicated that certain water-soluble phenolics offer renal protection. Thus, this study investigates the role of pre and post-treatment of rats with water-soluble phenolics from Phoenix dactylifera (PdP) against nephrotoxicity induced by cisplatin. Rats were either orally pretreated or post-treated with 200 mg/kg body weight of PdP before or after exposure to a single therapeutic dose of cisplatin (5 mg/kg body weight) for 7 successive days intraperitoneally. The protective effects of PdP against Cisplatin-induced nephrotoxicity was based on the evaluation of various biochemical and redox biomarkers, together with histopathological examination of kidney tissues. The composition, structural features, and antioxidative influence of PdP were determined based on chromatographic, spectroscopic, and in vitro antioxidative models. Cisplatin single exposure led to a substantial increase in the tested renal function biomarkers (uric acid, creatinine, and urea levels), associated with an increase in malondialdehyde indicating lipid peroxidation and a significant decline (p < 0.05) in reduced glutathione (GSH) levels in the renal tissue when compared with the control group. A marked decline exists in the kidney antioxidant enzymes (catalase, SOD, and GPx). Nevertheless, treatment with PdP significantly suppressed the heightened renal function markers, lipid peroxidation, and oxidative stress. Spectroscopic analysis revealed significant medicinal phenolics, and in vitro tests demonstrated antioxidative properties. Taken together, results from this study indicate that pre- and/or post-treatment strategies of PdP could serve therapeutic purposes in cisplatin-induced renal damage. [ABSTRACT FROM AUTHOR]

Background and Objectives: Diabetes mellitus is a chronic metabolic disease associated with several complications, including that of kidney disease. Plant-based dietary products have shown promise in mitigating these effects to improve kidney function and prevent tissue damage. This study assessed the possible favorable effects of beetroot extract (BE) in improving kidney function and preventing tissue damage in diabetic rats. Materials and Methods: Type 2 diabetes mellitus (T2DM) was induced using a low dose of streptozotocin (STZ). Both control and rats with pre-established T2DM were divided into six groups (each consisting of eight rats). All treatments were given by gavage and continued for 12 weeks. Fasting blood glucose levels, serum fasting insulin levels, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), serum triglycerides, cholesterol, low-density lipoprotein-cholesterol, serum and urinary albumin, and creatinine and urea levels were measured. Apart from this, glutathione, malondialdehyde, superoxide dismutase, tumor necrosis factor-α, and interleukine-6 in the kidney homogenates of all groups of rats were measured, and the histopathological evaluation of the kidney was also performed. Results: It was observed that treatment with BE increased body weight significantly (p ≤ 0.05) to be similar to that of control groups. Fasting glucose, insulin, HOMA-IR levels, and lipid profile in the plasma of the pre-established T2DM rats groups decreased to p ≤ 0.05 in the BE-treated rats as the BE concentration increased. Treatment with BE also improved the renal levels of oxidative stress and inflammatory markers, urinary albumin, and serum creatinine and urea levels. Unlike all other groups, only the kidney tissues of the T2DM + BE (500 mg/kg) rats group showed normal kidney tissue structure, which appears to be similar to those found in the kidney tissues of the control rats groups. Conclusion: we found that streptozotocin administration disturbed markers of kidney dysfunction. However, Beta vulgaris L. root extract reversed these changes through antioxidant, anti-inflammatory, and antiapoptotic mechanisms. [ABSTRACT FROM AUTHOR]

Background: Vitis vinifera is known for its antimicrobial activity; however, the hepatoprotective activity of aqueous extracts of aerial parts has also been reported, but the nephroprotective and hepatoprotective activity of ethanolic extracts have not yet been evaluated. Objective: To evaluate Vitis vinifera's hepatoprotective and nephroprotective activities against CCl4-induced toxicity in rats. Methods: Two doses of ethanolic extract of Vitis vinifera (100 and 200 mg/kg/day) were evaluated and compared with silymarin 100 mg/kg. Biochemical blood parameters like aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), Gamma-glutamyltranspeptidase (GGT), bilirubin, urea, uric acid, total protein and creatinine, and histopathologic changes of liver and kidney were studied and evaluated. Results: Vitis vinifera reduced the elevated blood levels of ALT, AST, ALP, urea, and creatinine, with the ethanol extract to 200 mg/kg/day being more effective. The histopathologic evaluation suggested that Vitis vinifera decreased hepatic and renal necrosis induced by CCl4. The more significant dose resulted in reductions in AST, ALT, GGT, ALP, and bilirubin of 54, 27, 56, 36, and 17%, respectively. Ethanolic extract 200 mg/kg/day also shows a reduction in elevated levels of Creatinine, Urea, Uric Acid, and Total Protein by 61%, 58%, 29%, and 9%, respectively. Conclusion: Hepatoprotective and nephroprotective activities of ethanol extract of Vitis vinifera were demonstrated, with ethanol extract to 200 mg/kg/day being the most effective. This presents scientific evidence for using medicinal plants such as Vitis vinifera in managing liver and kidney disorders.

Diabetic nephropathy (DN) has been linked to a number of long-term problems caused by diabetes mellitus. Inflammatory and oxidative stress pathways contribute to DN development and progression. Many studies have shown the preventive advantages of diets rich in substances like antiinflammatory and antioxidant elements like omega-3 fatty acids (n-3 FA) in preventing DN. Milkfish (Chanos chanos F.), patin (Pangasius micronema Blkr.), and snakehead fish (Chana striata Bloch) are fish oils which are known to contain n-3 FA. This study aims to evaluate the nephroprotective effect of three types of fish oils in a rat model of diabetes mellitus. Thirty male rats were used in this study. The animals were randomly divided into six groups (n = 5): the non-diabetic group, the diabetes mellitus group, the diabetic with 150 mg/kg metformin orally group, the diabetic with 1000 mg/kg milkfish oil orally group, the diabetic with 1000 mg/kg patin fish oil orally group, and the diabetic with 1000 mg/kg snakehead fish oil orally group. Diabetes models were induced using 65 mg/kg streptozotocin and 230 mg/kg nicotinamide intraperitoneally. The test was carried out for 8 weeks, followed by the observation of the biochemical profiles of blood, urine, oxidative stress, and the immunohistochemistry of the kidneys. A normally and homogeneously distributed test followed by a one-way analysis of variance (ANOVA) and the LSD post hoc test were used to analyse data at P 0.05. The results showed that serum creatinine levels did not differ significantly after the administration of milkfish, catfish, and snakehead fish oil for 8 weeks (p≥0.05). Different results were shown where the levels of serum BUN, uric acid, urine urea, and microalbumin urine were significantly different after administration of the three types of fish oil (p≤0.05). The same results were shown in oxidative stress (superoxide dismutase, glutathione, and malondialdehyde) and inflammation (interleukin-6 and tumor necrosis factor-α) profiles (p≤0.05).

Diabetes is a widespread health issue that impacts people all over the globe. The Equisetum ramosissimum L. plant has numerous traditional uses and pharmacological properties, including antidiabetic effects.The objective of this study was to thoroughly examine the advantages of incorporating extracts from the aerial components of E. ramosissimum to control diabetic nephropathy. The phytochemical constituents of E. ramosissimum extract were explored using phytochemical and HPLC analysis, focusing on phenols and flavonoid content. The effect of plant extract was evaluated on different kidney function parameters linked to diabetic nephropathy (fasting blood glucose, creatinine, uric acid, and urea) in streptozotocin induced-diabetic rats. Histopathological changes in the liver were also examined. The results showed methanol and ethanol extracts of E. ramosissimum have a total content of phenols (equivalent to gallic acid, 7.62 and 8.97 mg/g) and flavonoids (equivalent to quercetin, 8.87 and 12.86 mg/g), respectively. After conducting the UHPLC-MS/MS analysis, it was found that both the methanol and ethanol extracts contained isoferulic acid, ISO-Orientin, myristic acid, linoelaidic acid, rutin, and 3-Glu-7-Rha quercetin. Additionally, isoferulic acid, myristic acid, linoelaidic acid, rutin, and 3-Glu7-Rha quercetin were present in the extracts. The ethanol extract of E. ramosissimum significantly impacted STZ-induced diabetic mice by reducing their fasting blood glucose levels, and their creatinine and urea levels (P < 0.005). In conclusion, E. ramosissimum ethanol extract has shown potential effects to counteract some diabetes consequences on kidney function. Therefore, further studies are required to investigate its effect on other diabetes-related complications. [ABSTRACT FROM AUTHOR]

This study evaluated the nephroprotective and curative effects of methanol extract of Asystasia gangetica leaves on monosodium glutamate (MSG) challenged rats. The study adopted a completely randomized experimental design comprising 9 groups of rats. Group 1 served as the normal control, group 2 was MSG control, group 3 was MSG induced treated with silymarin. Groups 4 and 5 received only methanol extract of A. gangetica leaves, groups 6 and 7 (nephroprotective) were pre-treated with methanol extract of A. gangetica leaves for 7 days before receiving 8 g/kg MSG, while groups 8 and 9 (nephrocurative) received 8 g/kg MSG and treated with methanol extract of A. gangetica leaves for 14 days. Each of the treatments was given to the rats orally. The MSG caused significant elevation (p<0.05) of serum creatinine, urea, sodium ion, potassium ion, chloride ion and bicarbonate ion levels in the MSG control when compared with the normal control. The methanol extract of A. gangetica leaves had no significant effects (p>0.05) on the serum urea, creatinine and electrolyte levels of the extract control groups relative to the normal control. The nephroprotective and curative groups treated with graded doses of methanol extract of A. gangetica leaves had significantly reduced (p<0.05) creatinine, urea, sodium, potassium, chloride and bicarbonate levels with mild alterations in the kidney histo-architecture relative to the MSG control. The findings of this study indicated that methanol extract of A. gangetica leaves possesses nephroprotective and curative effects and could protect the kidney from the adverse effects of nephrotoxic agents.

Nephrotoxicity is one of the major complications and clinical limitations of gentamicin. This study aimed to evaluate the nephroprotective effect of dapsone against gentamycin-induced nephrotoxicity in rats. Twenty-four healthy rats weighing between (270-300) g were equally divided into three groups, eight rats in each group: control group received normal saline (2mL/kg/day I.P.) for 10 days , gentamicin group received (100 mg/kg/day I.P.) for 10 days, and dapsone group received (5 mg/kg/day p.o) concomitantly with gentamicin (100 mg/kg/day I.P.) for 10 days. At the end of experiment, blood and kidney tissue samples were collected from all animals for biochemical and histopathological examination. Dapsone exhibited nephroprotective effect manifested by a significant decrease in serum levels of BUN, creatinine and KIM-1 with a significant increase total protein serum level. Besides, it improves oxidative and inflammatory biomarkers of tissues, which was demonstrated by improving histological changes when compared to the gentamicin group. In conclusion, dapsone has a nephroprotective effect by counteracting the renal deleterious effect of gentamicin .

Background and Aim: Tessaria integrifolia Ruiz and Pav. (also known as “Pájaro bobo”) is known for its medicinal properties, including antiulcer, antiasthmatic, leishmanicidal, antipyretic, antispasmodic, diuretic, anti-inflammatory, analgesic, and hepatoprotective effects. Therefore, we aimed to evaluate its hepatoprotective and nephroprotective effects using a rat model of diclofenac-induced toxicity. Materials and Methods: We administered three different doses of the methanolic extract of T. integrifolia (100, 200, and 400 mg/kg/day orally) and compared them with the commercial medicine silymarin (100 mg/kg orally). The rats received the T. integrifolia extracts for 5 days, and on days 3 and 4, 1 h after receiving the extracts, diclofenac was administered intraperitoneally at a dose of 50 mg/kg. The animals were euthanized 48 h after the last diclofenac injection, and blood samples were obtained to measure biochemical parameters related to liver and kidney function, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, cholesterol, triglycerides, creatinine, and urea. Kidney and liver tissues were preserved in 10% formaldehyde and sent for histopathological analysis. Results: The results show that T. integrifolia has hepatoprotective and nephroprotective effects. These effects are verified by the lower blood levels of ALT, AST, urea, and creatinine compared to the diclofenac group, which exhibited elevated biochemical parameters. In addition, histopathological analysis showed that the groups that received T. integrifolia did not display necrosis or infiltration, which were observed in the diclofenac group. Conclusion: The methanolic extract of T. integrifolia has hepatoprotective and nephroprotective effects, with the highest protective activity observed at a dose of 400 mg/kg/day.

ABSTRACTCitrus essential oil (CEO) is obtained from the fruit of Genus Citrus, a flowering plant shrub in the family of the Rutaceae (Eremocitrus or Microcitrus) and extensively used in food, chemical industry, and traditional medicinal treatment owing to its pleasant aroma, antioxidant, and antiseptic properties. This review presents a botanical description, distribution, traditional uses, chemical composition, bioactive components, and the therapeutic uses as well as toxicological effects of the CEO. The objective was achieved via a comprehensive literature search of electronic databases such as Science Direct, PubMed, Web of Science, Wiley, ACS, Springer, Taylor and Francis, Google Scholar, SCOPUS, conference proceedings, thesis, and books until 2022 for publications. Citrus essential oils and their constituents are extracted and isolated either from the fruit peels, seeds, leaves, or flowers of the citrus plants. A comparative study of the sources of CEO confirmed its origin, ethnopharmacological and therapeutic uses. Over 2000 secondary metabolites have been isolated, with the main active constituents: being terpenes, monoterpenes, sesquiterpenes, and diterpenes. A comprehensive literature review revealed vast therapeutic benefits of CEO. Incomplete data report on in vitro and in vivo trials especially, on dosage, positive and negative control groups, intervention time, toxicity studies, phytochemical profiling, and clinical trials seem to be a knowledge gap.

Background: Although, gold nanoparticles (GNPs) are attracting more and more attention due to their ease of synthesis, modification and great potential value in biomedical application, exhibited harmful effects on human health and other living species. Quercetin (Qur) clarify diverse pharmacological effects specially anti-inflammatory, antiapoptotic, and antioxidant ones. Aim: This study aimed to evaluate the probable nephrotoxicity induced by different diameters of sphere GNPs, as well as the nephroprotective role of Qur. Methods: A total of fifty-four healthy mature male albino rats were grouped and treated with or without sphere GNPs; 10, 20 & 50 nm and quercetin (200 mg/kg b.wt.). The effects of GNPs and Qur were estimated through the collections of blood and kidney samples from euthanized rats and performed to biochemical, histopathological, and immunohistochemical investigations. Results: In comparison between different diameters of GNPs, the 10 nm GNPs revealed more significant elevations in all renal function parameters; Creatinine, Urea, BUN and Uric acid followed by 20 nm then 50 nm. Pre-cotreatment with Qur decreased all renal functional values. Histopathologically, 10 nm revealed the most potent renal pathological changes that represented in renal cortex with cloudy swelling of renal tubules, hypercellularity of some glomeruli, severe congestion of renal blood vessels, focal inter tubular edema, and vascular endotheliosis (degeneration of endothelium). In addition, the renal medulla revealed perivascular inflammatory cellular infiltration, perivascular fibrosis, intra tubular glycogen deposition and casts deposition of mainly cellular casts. On the other hand, Qur treatment ameliorated most of these pathological changes. Conclusion: The size of GNPs is pivotal in their pathological effect on renal tissues where the small-sized GNPs; 10 nm has more potent cytotoxic, inflammatory, and apoptotic effects rather than the larger ones. Otherwise, Qur clarified a significant mitigating role against the nephrotoxicity of the GNPs. [Open Vet J 2023; 13(6.000): 723-731]

Subsequently, nephroprotective effects of SeNPs against sodium arsenite (NaAsO2)-induced damages were confirmed by biochemical, molecular, and histopathological assays, including renal function, histological lesion, fibrosis, inflammation, oxidative stress-related damage, and apoptosis in mice renal tissues and renal tubular duct epithelial cells (HK2 cells).Results: The excellent biocompatibility and safety of SeNPs prepared in this study were confirmed by the non-significant differences in the renal functions and inflammation levels in mice between the negative control (NC) and 1 mg/kg SeNPs groups (p> 0.05). The results of biochemical, molecular, and histopathological assays confirmed that daily administration of 1 mg/kg SeNPs for 4 weeks not only ameliorated renal dysfunctions and injuries caused by NaAsO2 exposure but also inhibited the fibrosis, inflammation, oxidative stress-related damage, and apoptosis in the renal tissues of NaAsO2-exposed mice. In addition, altered viability, inflammation, oxidative stress-related damage, and apoptosis in the NaAsO2-exposed HK2 cells were effectively reversed after 100 μg/mL SeNPs supplementation.Conclusion: Our findings authentically confirmed the biosafety and nephroprotective effects of SeNPs against NaAsO2 exposure-induced damages by alleviating inflammation, oxidative stress-related damage, and apoptosis.Keywords: selenium nanoparticles, arsenite, nephroprotective, inflammation, oxidative stress, apoptosis

Background: The management of kidney injuries remains a big challenge and there is an urgent need to explore novel and alternative therapeutic strategies. Methods: The current study focused on the evaluation for the first time of the possible nephroprotective activity of the hydro-alcoholic extract (HE) and supernatant fraction (SUP) of Anogeissus leiocarpus roots against potassium dichromate (K2Cr2O7) induced nephrotoxicity in rats. The renal function parameters, the oxidative stress biomarkers in the nephrotoxic rats induced by the injection of a single dose (15 mg/kg, sc.) of K2Cr2O7, meanwhile treated orally with the HE (500 mg/kg/day) or SUP (100 mg/kg/day) were evaluated. The antioxidant activity was also evaluated in ex vivo and the in vitro anti-inflammatory activity was carried out. Results: The K2Cr2O7-induced nephrotoxicity was evident by the disturbance in the levels of the renal parameters such as urea, creatinine, proteins, electrolytes and the induction of oxidative stress. The majority of the renal parameters were significantly restored when the HE and SUP were administered to the nephrotoxic rats. Remarkably, in vivo the extracts significantly alleviated the oxidative stress by enhancing the antioxidant levels (GSH and CAT), and by lowering the MDA level as well as in ex vivo. Furthermore in vitro, the extracts exhibited a strong anti-inflammatory effect. Conclusion: The promising capacity of the HE and SUP to alleviate the K2Cr2O7-induced nephrotoxicity is mainly due to their antioxidant and anti-inflammatory activities.

Introduction: Despite modern sciences and advancements in new drugs or chemicals, the new era now rushes natural remedies for various illnesses and diseases that lead to end organ damage. In this study, we investigated Jatropha mollissima ethanolic extract’s effect against doxorubicin-induced cardiotoxicity and renal toxicity.Methods: To determine phytochemicals, a phytochemical screening was conducted. Various assays were used to measure the antioxidant activity, including the DPPH (2,2-diphenylpicrylhydrazyl), SOD (superoxide dismutase), NO (nitric oxide), and others. The antiproliferative effect of Jm was assessed by MTT assay; morphological analysis was performed using an inverted and phase contrast microscope, ultra morphological analysis of apoptosis with acridine orange (AO)/propidium iodide (PI) staining.Results: It was seen that doxorubicin caused elevated serum markers and abnormal changes in histological patterns. The significant reduction in cardiac and renal marker levels seen in groups given either 400 or 600 mg/kg of crude extract demonstrates that Jm has a protective effect against doxorubicin-induced cardiotoxicity due to the presence of active phytoconstituents having antioxidant potential. There is a dose-dependent decrease in cell viability when using J. mollissima. Apoptosis was observed in the treated cells.Conclusion: In conclusion, our research lends credence to the idea that J. mollissima could be used for cancer management and have cardioprotective and nephroprotective effects.

The present study was designed to evaluate the antiurolithiatic effect of PHYMIN-22 against ethylene glycol‐induced urolithiasis in rats. Healthy Albino male rats with 200–230 g body weight were randomly divided into five groups, each with 5 animals, control group, EG group (0.75%), PHYMIN-22 treatment group (0.75% EG 14 days and 100 mg/kg PHYMIN-22 next 14 days), PHYMIN-22 drug control group (100 mg/kg) and cystone treatment group (0.75% EG 14 days and 750 mg/kg cystone next 14 days). Biochemical testing was adopted for measuring the blood and urine parameters, as well as the level of antioxidants including superoxide dismutase (SOD), Catalase (Cat), Glutathione peroxidase (GPx) and glutathione (GSH) in kidney tissues. Hematoxylin and eosin (HE) staining was utilized to observe the histopathological changes in the kidney tissue. End of the experiment the PHYMIN-22 treatment reduced the urine and serum calcium (p < 0.01; p < 0.01), oxalate (p < 0.01; p < 0.01), phosphate (p < 0.01; p < 0.01), uric acid (p < 0.001; p < 0.001), protein (p < 0.001; p < 0.001), and creatinine (p < 0.001; p < 0.001) respectively, serum indicators ALT (p < 0.001) and AST (p < 0.001) level and non-enzymic antioxidant GSH (p < 0.001) compared to EG induced urolithiasis animals (Diseased control group). PHYMIN-22 treatment significantly increased urine volume, pH, and body weight, and antioxidants include CAT (p < 0.001; p < 0.001), SOD (p ˃ 0.05; p < 0.05), and GPX (p < 0.01; p < 0.001) compared to Diseased control group animals. The effect of PHYMIN-22 on EG-induced urolithiasis animals could be by improving kidney function, normalizing the urine and serum parameters, maintaining the kidney antioxidants, eliminating crystal deposition, and excretion of unwanted ions from the kidney and urinary tract.

This study was done to find the potential renal protective effects of sildenafil and its underlying mechanisms in mice with adenine-induced CKD. For the experiment, 40 male mice were split into four groups. The control group (A) received the same food without medication until the research ends, while the other three collections (B, C, and D) were given adenine (0.25% w/w in feed daily for 8 weeks), groups (C and D) were given sildenafil (0.5 and 2.5 mg/kg) respectively orally every day for 30 days, and then blood samples were taken to assess the function of the kidneys (Urea, total protein, and creatinine), total antioxidant capacity (TAC), superoxide dismutase (SOD), and catalase (CAT) in addition to kidney histopathology, as well as body and kidney weight. Administration of adenine caused weight loss, increased TAC, SOD, and CAT, and increased plasma concentrations of urea, total protein, and creatinine. Damage-related renal histopathological indicators (fibrosis and inflammation) were considerably elevated by adenine. Most of the aforementioned metrics improved with sildenafil, indicating that it might be utilized as an adjuvant treatment for CKD in people through antioxidant, anti-inflammatory, and antiapoptotic mechanisms.

The nutritional seeds from Macrotyloma uniflorum (MU) were studied for their unexplored beneficial effect in kidney diseases. Thus, the present study was designed to investigate the MU seed for its nephroprotective efficacy against cisplatininduced nephrotoxicity in an animal model. The nephroprotective potential for the Macrotyloma uniflorum seed extract (MUSE) was evaluated in albino rats (250 and 500 mg/kg; p.o.) for 10 days. At the end of the study, the nephroprotective effect was assessed based on the levels of various biochemical parameters of serum, urine, and kidney tissue. The GC-MS analyses of extract confirmed the antioxidant phytochemical constituents responsible for the nephroprotective activity. The MUSE treatment at 250 and 500 mg/kg p.o. showed a significant reduction in the levels of blood urea nitrogen (p<0.05), serum creatinine (p<0.01), serum urea (p<0.001), restore the urine volume (p<0.01), and urine creatinine (p<0.01) as compared to the negative control (cisplatin-injected rats). Subsequently, the abnormal conditions of creatinine clearance (p<0.05) and serum albumin (p<0.05) were restored to normal. For respective doses of 250 and 500 mg/kg p.o, the superoxide dismutase activity increased (p<0.05) to 82.91 and 98.8 U/g whilst the glutathione level significantly increased (p<0.01) to 36.24 and 46.17 µg/mg. Similarly, the catalase activity was significantly improved (p<0.001) to 485.9 and 573.5 µM/g with a significant reduction (p<0.001) in the level of the malondialdehyde to 84.56 and 68.56 nM/mg, respectively for low and high doses. The histopathology of kidney tissues confirmed the pronounced nephroprotection effect of MUSE against the cisplatin-induced injuries like tubular necrosis, hyaline cast, and vascular congestions. The major constituents found in GC-MS were inositol, ethyl alpha-d-glucopyranoside, n-hexadecanoic acid, 9, 12-octadecadienoic aci, 3-betastigmast-5-en-3-ol, Vitamin E, and stigmasterol. The results indicate the promising nephroprotective potential of Macrotyloma uniflorum seeds in nephrotoxicity induced rats, and the efficacy was comparable with vitamin E. [ABSTRACT FROM AUTHOR]

Background and Aim: Tessaria integrifolia Ruiz and Pav. (also known as "Pájaro bobo") is known for its medicinal properties, including antiulcer, antiasthmatic, leishmanicidal, antipyretic, antispasmodic, diuretic, anti-inflammatory, analgesic, and hepatoprotective effects. Therefore, we aimed to evaluate its hepatoprotective and nephroprotective effects using a rat model of diclofenac-induced toxicity. Materials and Methods: We administered three different doses of the methanolic extract of T. integrifolia (100, 200, and 400 mg/kg/day orally) and compared them with the commercial medicine silymarin (100 mg/kg orally). The rats received the T. integrifolia extracts for 5 days, and on days 3 and 4, 1 h after receiving the extracts, diclofenac was administered intraperitoneally at a dose of 50 mg/kg. The animals were euthanized 48 h after the last diclofenac injection, and blood samples were obtained to measure biochemical parameters related to liver and kidney function, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, cholesterol, triglycerides, creatinine, and urea. Kidney and liver tissues were preserved in 10% formaldehyde and sent for histopathological analysis. Results: The results show that T. integrifolia has hepatoprotective and nephroprotective effects. These effects are verified by the lower blood levels of ALT, AST, urea, and creatinine compared to the diclofenac group, which exhibited elevated biochemical parameters. In addition, histopathological analysis showed that the groups that received T. integrifolia did not display necrosis or infiltration, which were observed in the diclofenac group. Conclusion: The methanolic extract of T. integrifolia has hepatoprotective and nephroprotective effects, with the highest protective activity observed at a dose of 400 mg/kg/day.

Background: Organ damage, such as liver and kidney injury, is a serious and frequent problem leading to end-stage failure. Despite advances in research, there is still no proof of the effectiveness of potentially anti-inflammatory, antioxidant, and organoprotective compounds in therapeutic contexts. The need for potential therapeutic drugs is therefore enormous and urgent. For a long time, plant-based remedies, including Combretum glutinosum, have been a crucial component of healthcare. Methods: In order to develop anti-inflammatory, antioxidant, and organoprotective phytomedicine, the current research aims to evaluate the nephroprotective and hepatoprotective abilities of C. glutinosum extract, targeting its anti-inflammatory and antioxidant potential using ex vivo and In vitro models. Results: The phytochemical screening pointed out a large number of beneficial substances, including flavonoids, tannins, polyphenols, alkaloids, and terpenoids. C. glutinosum extract showed strong anti-inflammatory activity against heat and hypotonia-induced protein denaturation and membrane destabilization. Moreover, remarkable antioxidant action in DPPH radicals, ferric-reducing antioxidant power (FRAP), and Total Antioxidant Capacity (TAC) Ferric chloride/ascorbic acid (FeCl2-AA)-mediated lipid peroxidation in liver and kidney tissues was significantly (p < 0.001) mitigated by C. glutinosum extract. Conclusion: C. glutinosum has a good anti-inflammatory and antioxidant profile. This would place it among the potential candidates for hepatoprotective and nephroprotective activities.

To describe the kidney's response to specific substances, such as dangerous compounds and pharmaceuticals, the term "nephrotoxicity" is employed. When the body is subjected to toxins or medications, nephrotoxicity is among the most prevalent side effects. Numerous medical treatments, including anti-cancer medicines, antibiotics, and some Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), can cause nephrotoxicity. This review discusses a variety of drugs that can preserve the kidneys. The nephroprotective qualities of natural substances, medicinal plants, and dietary components have been examined. Medicinal plant chemicals have a significant role in pharmaceutical research. A wide range of herbs has been shown to have nephroprotective effects. Treatment of renal calculi, prevention of diabetic nephropathy, and reduction in tubular damage were all achieved. Plant-based therapies contain phytochemicals that have nephroprotective properties. Plants with nephroprotective activities have been reported on cisplatin, gentamicin, adriamycin, and urolithiasis, caffeic acid phenethyl ester assists in nephrotoxicity and free radicals radical scavenging activity, which may be utilized to prevent and treat kidney damage. In the end, investigating traditional medicines from Bangladesh that contain kidney-protecting plants is an intriguing new avenue of inquiry that could lead to effective new therapies for renal illnesses. Maintaining kidney health and enhancing the lives of countless people is only possible with further investigation into the beneficial effects of plants on renal function. However, it is crucial to find a middle ground between ancient practices and evidence-based modern medicine, stressing the importance of making educated decisions and following expert guidance to guarantee uncompromised kidney health.

Herein, we explored the protective effect of Leonotis ocymifolia (Burm.f.) Iwarsson aerial parts extract (LO) against cisplatin (CP)-induced nephrotoxicity in rats and profiled their phytocontents. A total of 31 compounds belonging to organic and phenolic acids and their glycosides as well as flavonoids and their Oand C-glycosides were identified through LC-MS/MS. The DPPH and FRAP assays revealed that the extract had powerful antioxidant properties. The in vivo results demonstrated that administering LO extract for 30 days (40 and 80 mg/kg b. w.) significantly improved the altered renal injury markers via reducing creatinine (high dose only) and uric acid levels compared to the Cp-group. The deleterious action of cisplatin on renal oxidative stress markers (GSH, MDA, SOD, and CAT) were also mitigated by LO-pretreatment. The reduction of the inflammatory marker (IL-6), and inhibition of DNA fragmentation, highlighted the prophylactic action of LO in kidney tissue. Molecular docking followed by a 100 ns molecular dynamic simulation analyses revealed that, amongst the 31 identified compounds in LO, chlorogenic and caffeoylmalic acids had the most stable binding to IL-6. The nephroprotective effects were further confirmed by histopathological observations, which showed improvement in ultrastructural changes induced by cisplatin. The observed findings reinforce the conclusion that L. ocymifolia extract exerts nephroprotective properties, which could be related to its antioxidant and anti-inflammatory activities. Further studies are required to determine the therapeutic doses and the proper administration time. [ABSTRACT FROM AUTHOR]

Chemotherapy-induced kidney damage is an emerging problem that restricts cancer treatment effectiveness. The proteasome inhibitor carfilzomib (CFZ) is primarily used to treat multiple myeloma and has been associated with severe renal injury in humans. CFZ-induced nephrotoxicity remains an unmet medical need, and there is an urgent need to find and develop a nephroprotective and antioxidant therapy for this condition. Thymoquinone (TQ) is a bioactive compound that has been isolated from Nigella sativa seeds. It has a wide range of pharmacological properties. Therefore, this experimental design aimed to study the effectiveness of TQ against CFZ-induced renal toxicity in rats. The first group of rats was a normal control (CNT); the second group received CFZ (4 mg/kg b.w.); the third and fourth groups received TQ (10 and 20 mg/kg b.w.) 2 h before receiving CFZ; the fifth group received only TQ (20 mg/kg b.w.). This experiment was conducted for 16 days, and at the end of the experiment, blood samples and kidney tissue were collected for biochemical assays. The results indicated that administration of CFZ significantly enhanced serum marker levels such as BUN, creatinine, and uric acid in the CFZ group. Similarly, it was also noticed that CFZ administration induced oxidative stress by reducing antioxidants (GSH) and antioxidant enzymes (CAT and SOD) and increasing lipid peroxidation. CFZ treatment also enhanced the expression of IL-1β, IL-6, and TNF-α production. Moreover, CFZ increased caspase-3 concentrations and reduced Nrf2 expression in the CFZ-administered group. However, treatment with 10 and 20 mg/kg TQ significantly decreased serum markers and increased antioxidant enzymes. TQ treatment considerably reduced IL-1β, IL-6, TNF-α, and caspase-3 concentrations. Overall, this biochemical estimation was also supported by histopathological outcomes. This study revealed that TQ administration significantly mitigated the negative effects of CFZ treatment on Nrf2 expression. Thus, it indicates that TQ may have utility as a potential drug to prevent CFZ-induced nephrotoxicity in the future. [ABSTRACT FROM AUTHOR]

The use of the chemotherapeutic agent doxorubicin is limited due to its potential to cause signifi-cant hepatorenal damage. The present study aimed to investigate the potential hepatoprotective and nephroprotective effects of Vernonia amygdalina, a medicinal plant with known antioxidant and anti-inflammatory properties, against doxorubicin-induced toxicity in rats. Male Wistar rats were randomly divided into four groups: Control, Doxorubicin (DOX), DOX + Vernonia Amyg-dalina (DOX+VA), and Vernonia amygdalina (VA) alone. DOX and DOX+VA groups were treated with a single intraperitoneal injection of doxorubicin (15 mg/kg body weight). The DOX+VA group received Vernonia amygdalina extract (100, 300, 500 mg/kg body weight) by oral gavage for 14 days following doxorubicin injection. The results demonstrated that Vernonia amygdalina significantly reduced the elevated levels of liver and kidney function biomarkers, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and creatinine, induced by doxorubicin. The histological examination of the liver and kidney tis-sues also confirmed the protective effects of Vernonia amygdalina against doxorubicin-induced damage. Furthermore, Vernonia amygdalina treatment was found to mitigate oxidative stress by restoring the levels of glutathione (GPx), Catalase, NO and SOD and decreasing the level of malondialdehyde (MDA) in liver and kidney tissues. Additionally, Vernonia amygdalina sig-nificantly suppressed the renal injury markers, NGAL, cystatin-c, KIM-1, and NAG. In conclu-sion, the results of this study suggest that Vernonia amygdalina has potent hepatoprotective and nephroprotective effects against doxorubicin-induced toxicity in rats. These protective effects are mediated by its antioxidant, and free radical scavenging properties. Further investigation is needed to determine the potential clinical relevance of Vernonia amygdalina in protecting against the hepatorenal damage induced by doxorubicin in human subjects.

Abstract Background Malaria continues to be a global problem due to the limited efficacy of current drugs and the natural products are a potential source for discovering new antimalarial agents. Therefore, the aims of this study were to investigate phytochemical properties, cytotoxic effect, antioxidant, and antiplasmodial activities of Sonchus arvensis L. leaf extracts both in vitro and in vivo. Methods The extracts from S. arvensis L. leaf were prepared by successive maceration with n-hexane, ethyl acetate, and ethanol, and then subjected to quantitative phytochemical analysis using standard methods. The antimalarial activities of crude extracts were tested in vitro against Plasmodium falciparum 3D7 strain while the Peter's 4-day suppressive test model with P. berghei-infected mice was used to evaluate the in vivo antiplasmodial, hepatoprotective, nephroprotective, and immunomodulatory activities. The cytotoxic tests were also carried out using human hepatic cell lines in [3(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) assay. Result The n-hexane, ethyl acetate, and ethanolic extracts of S. arvensis L. leaf exhibited good in vitro antiplasmodial activity with IC50 values 5.119 ± 3.27, 2.916 ± 2.34, and 8.026 ± 1.23 μg/mL, respectively. Each of the extracts also exhibited high antioxidant with low cytotoxic effects. Furthermore, the ethyl acetate extract showed in vivo antiplasmodial activity with ED50 = 46.31 ± 9.36 mg/kg body weight, as well as hepatoprotective, nephroprotective, and immunomodulatory activities in mice infected with P. berghei. Conclusion This study highlights the antiplasmodial activities of S. arvensis L. leaf ethyl acetate extract against P. falciparum and P. berghei as well as the antioxidant, nephroprotective, hepatoprotective, and immunomodulatory activities with low toxicity. These results indicate the potential of Sonchus arvensis L. to be developed into a new antimalarial drug candidate. However, the compounds and transmission-blocking strategies for malaria control of S. arvensis L. extracts are essential for further study.

Introduction: Nephrotoxicity is one of the most frequent kidney problems and happens when the body becomes exposed to medicine or toxin. Because renal tubular cells have metabolic activities, nephrotoxin can produce toxic components and cause damage. Paracetamol drug is safe when taken in therapeutic doses as an antipyretic and analgesic agent but its excessive doses may result in life-threatening renal impairment due to the generation of reactive-toxic metabolites. Scientific efforts are concentrated on discovering preventative or therapeutic medications to shield against the toxicity brought on by paracetamol due to nephrotoxicity. Silymarin, a medicine, is extracted from polyphenolic compounds found in the milk thistle plant. This plant has antioxidant, anti-inflammatory, anti-cancerous, and other properties and is the most commonly used drug for hepatic illnesses. Also, it has renal-protecting effects. Objective: This review research highlights the nephroprotective of silymarin against paracetamol-induced renal damage.
