The effect of C. borivilianum root on blood glucose, glycated hemoglobin (HbAIc), insulin and lipid profile levels in diabetes mellitus are not fully understood. This study therefore investigated the effect of C. borivilianum root on the above parameters and oxidative stress of the pancreas in diabetes.
C. borivilianum root aqueous extract (250 and 500 mg/kg/day) was administered to streptozotocin (STZ)-induced male diabetic rats for 28 days. Body weight, blood glucose, HbA1c, insulin, lipid profile levels and glucose homeostasis indices were determined. Histopathological changes and oxidative stress parameters i.e. lipid peroxidation (LPO) and antioxidant enzymes activity levels of the pancreas were investigated.
C. borivilianum root extract treatment to diabetic rats maintained near normal body weight, blood glucose, HbA1c, lipid profile and insulin levels with higher HOMA-β cell functioning index, number of Islets/pancreas, number of β-cells/Islets however with lower HOMA-insulin resistance (IR) index as compared to non-treated diabetic rats. Negative correlations between serum insulin and blood glucose, HbA1c, triglyceride (TG) and total cholesterol (TC) levels were observed. C. borivilianum root extract administration prevented the increase in lipid peroxidation and the decrease in activity levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) with mild histopathological changes in the pancreas of diabetic rats.
C. borivilianum root maintains near normal levels of these metabolites and prevented oxidative stress-induced damage to the pancreas in diabetes.
波棱瓜根对糖尿病患者血糖、糖化血红蛋白(HbAIc)、胰岛素和血脂水平的影响尚未完全明确。因此,本研究调查了波棱瓜根对上述参数以及糖尿病患者胰腺氧化应激的影响。
将波棱瓜根水提取物(250和500毫克/千克/天)给予链脲佐菌素(STZ)诱导的雄性糖尿病大鼠,持续28天。测定体重、血糖、HbA1c、胰岛素、血脂水平和葡萄糖稳态指数。研究胰腺的组织病理学变化和氧化应激参数,即脂质过氧化(LPO)和抗氧化酶活性水平。
与未治疗的糖尿病大鼠相比,用波棱瓜根提取物治疗的糖尿病大鼠维持了接近正常的体重、血糖、HbA1c、血脂和胰岛素水平,具有更高的HOMA-β细胞功能指数、胰岛/胰腺数量、β细胞/胰岛数量,但HOMA-胰岛素抵抗(IR)指数较低。观察到血清胰岛素与血糖、HbA1c、甘油三酯(TG)和总胆固醇(TC)水平之间呈负相关。给予波棱瓜根提取物可防止糖尿病大鼠胰腺脂质过氧化增加以及超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GPx)活性水平降低,且胰腺组织病理学变化轻微。
波棱瓜根维持了这些代谢物的接近正常水平,并预防了糖尿病中氧化应激诱导的胰腺损伤。
