摘要: 目的 研究莱茵衣藻对四氧嘧啶诱导胰岛素抵抗糖、脂代谢紊乱模型大鼠的辅助降血糖功效。方法 75只Wistar大鼠高热能饲料喂饲基础上,辅以腹腔注射四氧嘧啶105 mg/(kg·bw),以构建胰岛素抵抗糖、脂代谢紊乱模型。以0.5,1.0, 2.0 g/(kg·bw·d)剂量连续33 d经口给予莱茵衣藻粉测定空腹血糖及糖耐量指标,血清胆固醇(cholesterol,CHO)、三酰甘油(triglyceride,TG)及胰岛素抵抗指数,考察莱茵衣藻对大鼠辅助降血糖功能。同时20只Wistar大鼠分为剂量组[(2.0 g/(kg·bw·d)]和对照组,连续33 d经口给予莱茵衣藻粉并喂饲普通饲料测定空腹血糖值,考察莱茵衣藻对正常大鼠的降血糖功能。结果 对胰岛素抵抗糖、脂代谢紊乱模型大鼠,莱茵衣藻粉[2.0 g/(kg·bw·d)]血糖曲线下面积低于模型对照组,差异有统计学意义(P<0.05);糖耐量指标结果阳性;各剂量组的血脂(CHO和TG)与模型对照组比较无明显升高(P>0.05),莱茵衣藻粉对正常大鼠空腹血糖无影响(P>0.05)。结论 莱茵衣藻对胰岛素抵抗糖\脂代谢紊乱大鼠具有辅助降血糖功能。

Abstract: Objective To study the auxiliary hypoglycemic effect of Chlamydomonas reinhardtii on alloxan-induced insulin-resistant glucose/lipid metabolism metabolism disorder model rats. Methods Totally 75 Wistar rats were fed with a high-calorie diet supplemented with intraperitoneal injection of alloxan[105 mg/(kg·bw)] to establish an insulin-resistant glucose/lipid metabolism disorder model.The Chlamydomonas reinhardtii powder was orally administered at doses of 0.5,1.0 and 2.0 g/(kg·bw·d) for 33 consecutive days,and the fasting blood glucose and glucose tolerance index,serum cholesterol(CHO),triglyceride(TG) and insulin resistance index were measured,to investigate the auxiliary hypoglycemic effect of Chlamydomonas reinhardtii in rats.At the same time,20 Wistar rats were divided into a dose group[2.0 g/(kg·bw·d)] and a control group.They were orally given Chlamydomonas reinhardtii powder for 33 consecutive days and fed with common feed,and the fasting blood glucose was measured,to investigate the hypoglycemic effect of Chlamydomonas reinhardtii in normal rats. Results For insulin resistance glucose/lipid metabolism disorder model rats,the area under the blood glucose curve of Chlamydomonas reinhardtii powder[2.0 g/(kg·bw·d)] was lower than that of the model control group(P<0.05),and the result of glucose tolerance index was positive.Compared with the model control group,the blood lipid CHO and TG of each dose group had no significant increase(P>0.05). The Chlamydomonas reinhardtii powder had no effect on fasting blood glucose of normal rats. Conclusion The Chlamydomonas reinhardtii has an auxiliary hypoglycemic effect on insulin-resistant glucose/lipid metabolism disorder rats.
