摘要: 本文采用链脲佐菌素(STZ)诱导的糖尿病大鼠模型评价了芦笋老茎澄清汁(CAJ)的降血糖作用。腹腔注射STZ制备类似1型糖尿病大鼠模型,以0.6, 1.2和2.0 g/kg体重剂量的CAJ连续灌胃21天,监测血糖,测定糖化血清蛋白、血清胰岛素、肝糖原、脂代谢及抗氧化系统部分相关指标。结果显示,CAJ可明显降低糖尿病大鼠的血清葡萄糖、糖化血清蛋白、总胆固醇和MDA水平,并显著提高受试模型鼠的血清胰岛素水平、肝糖原含量、血清SOD活性、肝脏T-SOD、GSH-Px和CAT的活性。上述结果表明CAJ可有效降低糖尿病大鼠的血糖水平,刺激胰岛素分泌,调节血脂,增强抗氧化能力。

Abstract: The present study was designed to evaluate the hypoglycemic effect of clarified juice of Asparagus officinalis L. (CAJ) in streptozotocin (STZ) -induced diabetic rats. Diabetes in rats was induced by a single intraperitoneal injection of STZ. 0.6, 1.2 and 2.0 g/kg body weight CAJ were orally administered to diabetic rats once a day lasting for 21 days. Results showed that administration of CAJ significantly lowered the fasting serum glucose, glycosylated serum protein, total cholesterol and malondialdehyde levels in diabetic rats, but markedly increased serum insulin level, hepatic glycogen content, activities of superoxide dismutase in serum and liver and activities of hepatic glutathione peroxidase and catalase. These results suggested that CAJ might have hypoglycemic, insulin-stimulating, hypotriglyceridemic and antioxidant effects in STZ induced diabetic rats.

Key words: clarified asparagus juice (CAJ), streptozotocin, diabetic rats, hypoglycemic activeity
