刺激肌肉和其他组织使他们摄取葡萄糖一般认为是胰岛素最特殊与重要的作用之一。这一促进作用无疑是给与胰岛素后血糖降低的主要原因。在若干类型的糖尿病中血糖的异常升高大部分是由于缺乏这一作用。因此研究对摄取葡萄糖的促进作用,应该是研究胰岛素作用所在的适当方法。为了讨论方便,可将肌肉摄取葡萄糖分为三步:(1)葡萄糖从血浆转移到细胞。(2)糖经过细胞膜的运输。(3)葡萄糖在细胞内的代谢或利用。既然这些步骤是顺序衔接的,因此摄取的总速度
Stimulating muscles and other tissues to make them ingest glucose is generally considered one of the most special and important effects of insulin. This promotion is undoubtedly the main reason for lowering blood glucose after insulin administration. The abnormal increase in blood glucose in several types of diabetes is due in large part to the lack of this effect. Therefore, the promotion of glucose uptake should be the appropriate method to study the effect of insulin. For the sake of discussion, muscle glucose uptake can be divided into three steps: (1) glucose is transferred from the plasma to the cell. (2) transport of sugar through the cell membrane. (3) metabolism or utilization of glucose in cells. Since these steps are sequential, the total speed of ingestion
