摘要
探讨糖尿病(DM)大鼠心肌胰岛素含量变化与Se和维生素E(VE)之间的关系。方法:应用低Se复加注射链脲佐菌素(STZ)制造DM模型,结合放免分析技术检测血清与心肌胰岛素含量。结果:低Se、低VEDM大鼠心肌胰岛素含量明显减少,单纯补Se或VE对心肌胰岛素含量的影响无统计学意义,而联合补Se和VE则显著提高了DM大鼠心肌胰岛素水平。结论:DM时,Se和VE所产生的联合生物学效应可以明显改善心肌细胞对胰岛素的摄取和利用,对改善DM时心肌细胞代谢与机能,防止DM心肌病变的发生发展可能起一定作用。
Abstract Objective: The relationship between Se, VE and insulin contents in myocardium was investigated in Sedeficient DM rats. Methods: On the basis of Sedeficient rat model, the injection of STZ was used to induce DM model. The insulin level in myocardium, serum, and pancreas was measured by RIA method. Results: Both Se and VE deficiency led to the decrease of insulin content in myocardium. The diets supplemented with either Se or VE failed to increase the insulin contents. However, supplementation of both Se and VE significantly increased the insulin level in myocardium. Conclusion:It suggests that combined Se and VE may increase the insulin intake and utilization in myocardic cells in DM rats, and it may play an important role in protecting myocardium from DM myocardial lesions. Key words: diabetes myocardium insulin selenium Vitamin E
