    摘要:

    目的 研究麦芪降糖丸对ob/ ob 小鼠血糖的影响?方法 8 周龄雄性ob/ ob 小鼠随机分成模型组,麦芪降糖丸高?中?低剂量(8 g/ kg?4 g/ kg?2 g/ kg)组和二甲双胍(250 mg/ kg)组,各给药组分别灌胃给予相应剂量的药物,每天1 次,连续10 周,同周龄正常对照组C57BL/6 J 小鼠和模型对照组ob/ ob 小鼠给予等体积的溶剂?检测每组小鼠日平均进食量和体重?空腹血糖?血清胰岛素水平和胰腺病理变化?结果 麦芪降糖丸给药2 周?6 周?8 周?10 周时能明显降低ob/ ob 小鼠空腹血糖( P < 0. 05, P < 0. 01),给药10 周对小鼠日平均进食量和体重无明显影响,能减轻ob/ ob 小鼠的胰腺胰岛细胞的病变程度,提高ob/ ob 小鼠空腹血清胰岛素水平( P < 0. 05)?结论 麦芪降糖丸能降低ob/ ob 小鼠血糖,可能与减轻胰腺病理损伤,促进胰岛素分泌有关?

    Abstract:

    Objective To investigate the effects of a Chinese medicine, Mai Qi Jiang Tang pill,on the bloodglucose level in ob/ ob mice. Methods Eight-week old male ob/ ob mice were randomly divided into Mai Qi Jiang Tang pillhigh (8 g/ kg), medium (4 g/ kg), and low (2 g/ kg) dose groups, as well as a metformin (250 m g/ kg) group, wereorally administered drugs once daily for 10 weeks. Age-matched C57BL/6 J control mice and ob/ ob mice were orallyadministered an equal volume of vehicle. Average food consumption per day and body weights of the mice were recorded,and fasting blood glucose and insulin levels were measured using a glycemic instrument and enzyme-linked immunosorbentassay, respectively. Pathological changes of the pancreas were observed using hematoxylin and eosin staining. Results Compared with the control ob/ ob mice, ob/ ob mice administered Mai Qi Jiang Tang pill exhibited significantly decreasedfasting blood glucose levels at 2, 6, 8, and 10 weeks after treatment ( P < 0. 05, P < 0. 01). Mai Qi Jiang Tang pill alsoattenuated the degree of pathological changes observed in islet cells and increased serum insulin levels ( P < 0. 05), butelicited no significant difference in body weight or average food consumption per day at 10 weeks after treatment.Conclusions Mai Qi Jiang Tang pill can decrease blood glucose levels of ob/ ob mice, which may be related to the amelioration of pancreatic pathology and promotion of insulin secretion.
