Tropical species contains a high level of phenolic acids and flavonoids, which were found to inhibit some key enzymes associated with the incidence of type 2 diabetes in in vitro and in vivo models based on earlier studies. This study was further designed to compare the nutritional properties, glycemic index, and hypolipidemic and the antioxidant effects of three species of tropical eggplant fruit (, and ) diet on streptozotocin (STZ)-induced nephrotoxicity in male Wistar rats. The animal model was subjected to high-fat diet prior to interperitional administration of streptozotocin (35 mg/kg wt); thereafter, the rats were given supplemented eggplant fruit diet, which lasted for 14 days. Determination of lipid content [triglycerides (TG), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and total cholesterol (TC)], was assessed, while the liver biomarker enzymes alanine aminotransferase (ALT) alkaline phosphatase (ALP) and aspartate aminotransferase (AST), also endogenous enzymes such as superoxide dismutase (SOD) and catalase (CAT), were determined. Histopathological assessment of inflammation was carried out on kidney while the blood urea nitrogen (BUN), uric acid, and creatinine level on the kidney function were determined. The results showed that the groups with supplemented eggplant diet had significant ( < 0.05) reduction in lipid profile, decreased leakages of the liver, and kidney function enzymes while there was restoration of depleted endogenous antioxidant enzymes. The inflammatory cells and fat deposit from the histopathological view were reduced. However, had the best nutritional output.
热带物种含有高水平的酚酸和黄酮类化合物,根据早期研究,在体外和体内模型中发现这些化合物可抑制一些与2型糖尿病发病相关的关键酶。本研究进一步设计比较三种热带茄子果实(、和)饮食对链脲佐菌素(STZ)诱导的雄性Wistar大鼠肾毒性的营养特性、血糖指数、降血脂和抗氧化作用。在腹腔注射链脲佐菌素(35mg/kg体重)之前,动物模型接受高脂饮食;此后,给大鼠补充茄子果实饮食,持续14天。测定脂质含量[甘油三酯(TG)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)和总胆固醇(TC)],同时测定肝脏生物标志物酶丙氨酸转氨酶(ALT)、碱性磷酸酶(ALP)和天冬氨酸转氨酶(AST),以及内源性酶如超氧化物歧化酶(SOD)和过氧化氢酶(CAT)。对肾脏进行炎症的组织病理学评估,同时测定肾功能的血尿素氮(BUN)、尿酸和肌酐水平。结果表明,补充茄子饮食的组脂质谱显著降低(<0.05),肝脏和肾功能酶的泄漏减少,而耗尽的内源性抗氧化酶得到恢复。从组织病理学角度来看,炎症细胞和脂肪沉积减少。然而,的营养输出最佳。
