Cisplatin is a chemotherapeutic agent, but the therapeutic utility is limited due to its dose dependent nephrotoxicity. The aim of the present study was to evaluate the nephroprotective effect of pomegranate in cisplatin-induced acute kidney injury. Wistar rats were allocated into six groups as follows: the normal control, cisplatin-induced, pomegranate rind extract treatment (50, 100 and 200 mg kg(-1)) and pomegranate rind extract per se group. All the experimental test drugs/vehicle were administered orally for a period of ten days. Intraperitoneal injection of cisplatin (8 mg kg(-1)) was administered on day 7 to all the groups except the normal control and pomegranate per se group. On day 10, cisplatin resulted in significant nephrotoxicity in Wistar rats with a drastic elevation of serum creatinine and BUN, a decline in the concentrations of GSH, MDA and superoxide dismutase (SOD), and an elevation in the TNF-α level in renal tissues. Pathological changes in renal tissues were examined by histopathology and dysfunction in mitochondria and proximal tubule cells was detected by transmission electron microscopy. The rate of apoptosis and the expression of caspase-3, Il-1β and IL-6 in rat renal tissues were detected by immunohistochemistry. The administration of pomegranate at a dose of 200 mg per kg body weight significantly (p < 0.001) ameliorates increased serum creatinine and BUN. In parallel to this, pomegranate also exhibits anti-apoptotic activity through the reduction of active caspase-3 expression in kidneys. Additionally, in-silico studies also confirmed a renoprotective effect of pomegranate. The above findings suggest that pomegranate can be used as a dietary supplement in the treatment of cisplatin-induced kidney injury by reducing apoptosis, oxidative stress and inflammation.
In the present study, we have evaluated the nephroprotective effect of hydroalcoholic extract of Terminalia chebula in cisplatin-induced nephrotoxicity model. Standardised extract was orally administered to Wistar rats for 10 days at different doses. On day 7, 8 mg/kg of cisplatin was administered intra-peritoneally to rats in all groups. T. chebula, in a dose-dependent manner significantly inhibited the elevation of serum creatinine, blood urea nitrogen and oxidant stress markers. The immunohistochemical analysis revealed the increased levels of apoptotic markers and cytokines in cisplatin group were significantly lowered by T. chebula extract. The cisplatin-treated rats kidney showed diffused tubular necrosis and infilteration of inflammatory cells which was reversed in the treatment group. Chemical characterisation of extract by HPLC revealed the presence of corilagin, chebulinic, chebulagic, chebulic, gallic and ellagic acid. The findings of this study discovered that T. chebula ameliorated oxidative and histological damage caused by cisplatin.
Introduction:Dyslipidemia is one of the most common risk factor for cardiac-related disorders in diabetes mellitus. Diabetic dyslipidemia is characterized by hypertriglyceridemia, low high density lipoprotein and elevated low density lipoprotein concentration.Aim:To explore the effect of Lawsonia inermis hydroalcoholic extract (LIHE) for diabetic dyslipidemic activity along with its safety profile.Materials and Methods:LIHE administered at doses of 100, 200 and 400 mg/kg in rats after induction of hyperglycemia by alloxan. Insulin (1 IU/kg), glibenclamide (2.5 mg/kg), and metformin (100 mg/kg) were used as positive control and 1% gum acacia as normal control. Statistical analysis was performed using one-way analysis of variance, followed by Dunnett's t-test.Results:The percentage reduction in blood glucose level of LIHE at dose of 400 mg/kg was 39.08% on day 21 when compared to baseline (day 0), which is comparable to glibenclamide (44.77%) and metformin (46.30%). Decrease in blood glucose level exhibited significant improvement in lipid profile, plasma albumin, total plasma protein and serum creatinine.Conclusion:Results of this study demonstrated that LIHE significantly improved lipid and lipoprotein pattern observed in diabetic rats and this could be due to improvement in insulin secretion or action, thus has potential to be used in treatment of diabetes mellitus associated dyslipidemia.
