The aim of present investigation was to study the effects of Mesembryanthemum forsskalei Hochst (Samh) seeds in streptozotocin-induced diabetic rats. Thirty rats were administrated with streptozotocin to induce diabetes and 6 rats were used as untreated diabetic control. Diabetic rats were fed with 5 and 15% Samh seed alone and in combination with fatty diet i.e. 2% Cholesterol for 6 weeks. Effects of Samh seed on blood glucose levels, lipid profiles and enzyme activities of diabetic rats were examined. In addition, total cholesterol (TC), triglyceride (TG) and high density lipoprotein-cholesterol (HDL-C) were determined. Diabetic rats treated with 15% Samh seed diet were significantly decreased the level of TC (40%), TG (46%) and HDL-C (31%) respectively. Whereas, there was no significant effects observed in the glucose level in 15% Samh seeds treated rats for 6 weeks. A decrease in enzymes levels, AST (58.2%), LDH (1.6%), ALT (24.3%) and ALP (5.38%) in 5% Samh seeds diet treated rats were observed and were found near to untreated control. Findings from present study demonstrated that non fatty Samh seeds diet could have hypoglycemic and antihyperlipidemic effects in diabetic rats and could be useful model for the treatment of diabetic patients.
本研究旨在探讨南非马齿苋(Mesembryanthemum forsskalei Hochst(Samh)种子)对链脲佐菌素诱导的糖尿病大鼠的影响。30 只大鼠给予链脲佐菌素诱导糖尿病,6 只大鼠作为未处理的糖尿病对照。糖尿病大鼠单独给予 5%和 15%的 Samh 种子以及与高脂肪饮食(即 2%胆固醇)联合喂养 6 周。检测 Samh 种子对糖尿病大鼠血糖水平、血脂谱和酶活性的影响。此外,还测定了总胆固醇(TC)、甘油三酯(TG)和高密度脂蛋白胆固醇(HDL-C)。用 15% Samh 种子饮食治疗的糖尿病大鼠,TC(40%)、TG(46%)和 HDL-C(31%)水平显著降低。然而,在 15% Samh 种子治疗的大鼠中,血糖水平在 6 周内没有显著变化。在 5% Samh 种子饮食治疗的大鼠中,观察到 AST(58.2%)、LDH(1.6%)、ALT(24.3%)和 ALP(5.38%)的酶水平降低,且接近未处理的对照组。本研究的结果表明,非脂肪 Samh 种子饮食可能对糖尿病大鼠具有降血糖和抗高血脂作用,可作为糖尿病患者治疗的有用模型。
