ABSTRACT
There has been increasing search for the ameliorative properties of seed oils against toxicants. bisphenol A acts as an estrogenic endocrine-disrupting chemical capable of causing male infertility. This study aimed to explore Cucumeropsis mannii seed oil effects against mitochondrial damage in rats using bisphenol A. Forty-eight rats were randomly assigned to six groups (n = 6) of eight rats each and fed the same food and water for 6 weeks. The group A rats were given 1 mL olive oil, while the ones in group B were given bisphenol A at 100 mL/kg body weight via oral route. Group C received C. mannii seed oil 7.5 mL/kg body weight C. mannii seed oil, while group D, group E, and group F were pre-administered bisphenol A at 100 mL/kg body weight, followed by treatment with C. mannii seed oil at 7.5, 5, and 2.5 mL/kg body weight, respectively. Antioxidant enzymes, glutathione, reactive oxygen species, testicular volume, malondialdehyde, body weight, and testicular studies were done using standard methods. The results of the bisphenol A-administered group showed a significant decrease in the antioxidant enzymes, glutathione, body weight, and testicular volume with elevation in the levels of reactive oxygen species, malondialdehyde, and testicular indices. BPA + CMSO-treated group showed a significant increase in GPx activity compared with BPA-exposed rats. CMSO treatment significantly increased catalase activity in comparison with that of rats exposed to BPA. Remarkably, C. mannii seed oil and bisphenol A co-administration significantly reversed the abnormalities observed in the dysregulated biochemical biomarkers. Our findings suggest that C. mannii seed oil has considerable antioxidant potential which can be explored in therapeutic development against systemic toxicity induced by exposure to bisphenol A. Cucumeropsis mannii seed oil protects against bisphenol A-induced testicular mitochondria damages.
ABSTRACT
Effects of ethanolic extracts of leaf, seed and fruit of Datura metel on kidney function of male albino rats was investigated in this study. The result showed a non-significant (p > 0.05) increase of urea concentration in groups 2 and 3 administered low (300 mg/kg bw) and high (600 mg/kg bw) dose of leaf extract respectively and a non-significant (p > 0.05) decrease in all groups administered the seed and fruit extracts compared with normal control (group 1). Creatinine increased significantly (p < 0.05) in groups 4 and 7 administered low dose (300 mg/kg bw) of seed extract and high dose (600 mg/kg bw) of fruit extract respectively, but increased non-significantly in other groups (2, 3, 5 & 6) compared with normal control. Sodium, potassium and bicarbonate concentrations increased non-significantly (p > 0.05) in all groups administered the various extracts, except in group 4 in which sodium reduced non-significantly (p > 0.05) compared with normal control. Chloride increased significantly (p < 0.05) in group 5 and non-significantly (p > 0.05) in groups 3, 6 and 7, but reduced non-significantly (p > 0.05) in group 4 compared with normal control. The administration of some of the extracts in comparison with the normal control in histology of the animals show glomerular extrusion and glomerular collapse with resultant increased urinary space, dilated tubules, vacuolations in some epithelial lining of most of the tubules in the medulla and inflammatory cellular infiltration at some peritubular regions. The results showed that some parts of Datura metel posed mild negative effects, while some parts could possess nephroprotective potential by regulating the kidney function of male albino rats.
