The effects of fibre-enriched biscuit on biomarkers associated with hepatotoxicity in diabetic rats were investigated. Diabetes was induced by single intraperitoneal injection of alloxan monohydrate. Treatment lasted for 14 days after which the rats were sacrificed by cervical dislocation. Blood serum was analyzed to determine hepatic function enzymes. The liver was also analyzed to determine hepatic lipid profile and antioxidant enzymes. Induction of diabetes led to elevated levels of ALP, AST, and ALT. These were, however, significantly (p < 0.05) reduced in the fibre-enriched biscuit fed (treated) group. There was no significant difference in the serum bilirubin and total protein levels of the studied groups. Reduced albumin level was observed in the diabetic group; this was further lowered on feeding with fibre-enriched biscuits. Induction of diabetes led to increased hepatic level of cholesterol, triglyceride (TG), low density lipoprotein (LDL), and lipid peroxidation and decreased activities of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) and HDL level. These were significantly (p < 0.05) reversed on feeding with fibre-enriched biscuit. This study portrays the protective effect of fibre-enriched biscuit on increased oxidative stress and hyperlipidemia in hepatic tissues of alloxan-induced diabetic rats.
This study shows an improvement in testicular antioxidant activities and sperm qualities by single and double doses of the formulation, suggesting its protective potential against testicular toxicity in diabetic rats.
The cardiovascular protective and hypolipidemia e f f e c t s o f s o y b e a n o i l w e r e i n v e s t i g a t e d i n normocholesteremic rats. Diets were prepared and designed to contain 50 % of energy as carbohydrate, 35 % as fat, and 15 % as protein. Groups of six rats were each fed one of these diets, while a group was fed pelletized mouse chow which served as the control. A significant reduction (p<0.05) was observed in the cholesterol, triglyceride, and low-density lipoprotein (LDL) levels of the soybean oil fed group. There was no significant alteration in the high-density lipoprotein (HDL) levels of all the groups. The studied atherogenic indices were significantly low in the soybean oil fed group compared to the other groups. These results indicate a protective effect of soybean oil against the development of cardiovascular disease as well as the hyperlipidemia that characterize obesity, hypertension, and diabetes mellitus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
