Contemplation Impact of Pulp Seeds Cucurbita Pepo L. and its Paste on Oxidative Stress in Rats

Abstract

Cucurbita Pepo L. seeds and seeds paste which are rich sources of phytochemicals and act as a rich source of antioxidants. The most important phytochemicals present in the cucurbits are cucurbitacin’s, saponins, carotenoids, phytosterols, and polyphenols. These bioactive phyto-constituents are responsible for the pharmacological effects including antioxidant effect. Aim of this study was to investigate the effect of Cucurbita Pepo L. seeds and seeds paste on rats suffering from oxidative stress. Thirty-six male albino rats were used in the experiment (Sprague-Dawley strain). The animals randomly divided 6 rats each group according to the following the first Group: Rats were fed basal diet and set as negative control. The other rats (n = 30) were fed on basal diet containing monosodium glutamate (120 mg/kg) for induce stress condition. After that, rats further divided into 5 groups (n = 6) each for six weeks as follows: -2^nd Group: Rats were fed on basal diet containing monosodium glutamate and set as positive control. 3^rd Group: Rats were fed on diet containing monosodium glutamate with addition of Cucurbita Pepo L. seeds 5%. 4^th Group: Rats were fed on diet containing monosodium glutamate with addition of Cucurbita Pepo L. seeds 10%. 5^th Group: Rats were fed on diet containing monosodium glutamate with addition of Cucurbita Pepo L. seeds paste 5%. 6^th Group: Rats were fed on diet containing monosodium glutamate with addition of Cucurbita Pepo L. seeds paste 10%. The experimental period was six weeks; Blood samples were collected. At the end of the experiment, the results showed that using seeds 5% & 10% and seeds paste 5% & 10% in feeding the stressed rats increased (BWG%, FI, FER, Superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx)) with highest results in group fed on 10% seeds paste and decreased (Urea, Creatinine, ALT, AST, IL-6 and INF-gamma) with lowest results in group fed on 10% Cucurbita Pepo L. seeds paste.
