摘 要: | 目的:研究益肾活血胶囊(yishenhuoxue capsule,YSHXC)、二甲双胍(metformin,met)对D-半乳糖(D-galactose,D-gal)诱导大鼠糖耐量减退(Impaired Glucose Tolerance,IGT)的影响。方法:以ip D-gal 150mg kg-1,qd×56d诱导胰岛素抵抗(insulin resistance,IR),IGT大鼠模型,测其空腹血糖(fasting blood glucose,FBG)和口服葡萄糖耐量试验(Oral Glucose Tolerancetest,OGTT)后2h血糖(2-hours Blood Glucose,2h BG)含量及空腹血清胰岛素水平(fasting serum insulin,FINS);并观察YSHXC2个剂量、met对病鼠FBG、2h BG及FINS的效应。结果:正常对照组、YSHXC 2个剂量和met与模型组相比较,FBG均未见明显影响,差异未见显著性(P〉0.05);而OGTT后2hBG,模型组明显高于正常对照组(P〈0.01),说明D-gal致大鼠IGT模型成立;YSHXC 2个剂量和met均能抑制OGTT后2h BG的升高,差异均有高度显著性(P〈0.01),FBG与OGTT后2H BG间差值降低,差异均有高度显著性(P〈0.01),同时YSHXC 2个剂量同模型组相比均降低了病鼠的FINS水平,差异均有高度显著性(P〈0.01),说明各药均能改善D-gal致IR模型大鼠的IGT。结论:D-gal可诱导以IGT为表现的IR,其机制可能与D-gal诱导蛋白非酶糖基化-氧化应激-自由基损伤作用和直接干扰糖脂代谢有关;益肾活血胶囊与met一样,能改善D-gal诱导IR大鼠的糖耐量以及由糖耐量低减所引起的高胰岛素血症。

Abstract: | Objective: To investigate the effects of Yishen Huoxue(YSHX) capsule,metformin on blood glucose(BG) and fasting serum insulin level in D-galactose(D-gal)-induced rats with impaired glucose intolerance(IGT).Methods: To study the model in D-gal(150mg kg-1,intraperitoneally injected,qd×56d)-induced rats with IGT that fasting blood glucose(FBG),fasting serum insulin(FINS),and 2-hours blood glucose(2h BG) after oral glucose tolerance test(OGTT),and the effects of YSHX capsule and metformin were observed in the rats with IGT;Result: Any group in the experiment were not difference in FBG(P>0.05),but in 2h BG after OGTT,compared with control group content of glucose was increased in rats administered D-gal(P<0.01),namely D-gal induced IGT;low dosage group of YSHX capsule and metformin lowered 2h BG after OGTT,and high and low dosage groups of YSHX capsule lowered FINS compared with D-gal administration group(P<0.01),and improved IGT in D-gal-induced IR rats.Conclusion: The results suggest that D-gal can induce IGT that it results from proteinic non-enzymatic glycation,oxidative stress-free radical injure and glucose-fatty metabolism disturbed;these dosages of YSHX capsule and metformin can antagonize D-gal-induced insulin resistance and improved IGT. |
