The study evaluated the effect of dietary inclusion of pumpkin (Cucurbita pepo L) seed (raw and roasted) on nephrotoxicity caused by cisplatin in rats. Rats were divided into control group, cisplatin-induced nephrotoxic untreated group, nephrotoxic-treated groups with Methimazole, dietary regimen containing raw pumpkin seed (5% and 10%) and roasted pumpkin seed (5% and 10%) for 14 days. Results acquired uncovered that cisplatin intoxication significantly increased (p ≤ .05) the levels of renal biomarkers, arginase activity, 8-hydroxy-2-deoxy guanosine (8-OHdG), malondialdehyde (MDA), and reactive oxygen species (ROS) levels as well as significant decrease in functional sulfhydryl groups, nitric oxide levels, and antioxidant enzyme activities in rats' kidney when compared to the control group. These adverse changes, due to cisplatin inebriation in rodents, were in any case, forestalled by pre-treatment with pumpkin seed inclusive diet. This holds promise for the use of pumpkin seed as a food supplement in the management of nephrotoxic-related disorders. PRACTICAL APPLICATIONS: These results suggest that roasted pumpkin seed appears to be more nephroprotective than the raw pumpkin seed through regulations of arginase activity, enhancement in the antioxidant system, suppression of renal markers and lipid peroxidation. This holds p-omise for the use of roasted pumpkin seed as a food supplement in the management nephrotoxic-related disorders.
