血竭对大鼠血糖、血浆胰岛素及血脂的影响

Effects of Resina Draconis on the Levels of Plasma Glucose, Insulin and Lipids in Rats

目的观察血竭对大鼠血糖、血浆胰岛素及血脂的影响。方法用葡萄糖或肾上腺素造成大鼠生理性高血糖模型 ,用四氧嘧啶造成大鼠糖尿病模型 ,观察血竭对上述模型动物血糖、血浆胰岛素、血浆总胆固醇、甘油三酯、高密度脂蛋白胆固醇的作用。结果血竭对正常大鼠空腹血糖无明显降低作用 ,但对葡萄糖及肾上腺素所致高血糖大鼠的血糖水平有降低作用 ,能改善大鼠对葡萄糖的耐受能力 ;能降低四氧嘧啶诱导的糖尿病大鼠的空腹血糖水平 ,增加正常大鼠及糖尿病大鼠的胰岛素分泌 ;有一定的降血脂作用。结论血竭对多种原因引起的动物高血糖均有较好的治疗作用和一定的降血脂作用。

Objective:To investigate the effects of Resina Draconis on the levels of plasma glucose,insulin and lipids in normal and diabetic rats. Methods: Hyperglycemia rat models were induced by glucose or adrenaline and rat models with diabetes mellitus were induced by alloxan.The levels of plasma glucose, insulin and lipids (triglyceride, total cholesterol and HDL-C) were determined. Results: Resina Draconis had no obvious effects in decreasing the plasma sugar level in normal fasted rats but could decrease the plasma sugar level and improve the glucose-resistance in glucose-induced or adrenaline-induced hyperglycemic rats and alloxan-induced fasted diabetic rats and increase insulin secretion in both normal and diabetic rats. It could also decrease the plasma lipid level in alloxan-induced diabetic rats. Conclusion: Resina Draconise exerts a good therapeutic effect on hyperglycemia in diabetic rats and its mechanism may be related to the increase of the secretion of insulin.
