胰岛素是脊椎动物体内的重要激素,对代谢有广泛而强大的影响。它的功能正常是保证人体健康的重要条件。例如糖尿病就是一种与胰岛素功能异常有密切关系的常见病。有人估计全世界糖尿病患者达两亿以上,美国糖尿病患者超过一千万,发病率高达5％,某些地区甚至高达50％,我国糖尿病发病率可能较低,据《实用内科学》(1973年版)估计,低于1％。但是随着我国卫生医疗条件的改善,平均寿命的延长,诊断水平的提高,估计今后发现的糖尿病患者会有所增多。因此,在我国糖尿病也是一个值得引起重视的问题。胰岛素的化学本质是蛋白质。“生命是蛋白体的存在方式”(恩格斯)。研究
Insulin is an important hormone in vertebrates and has a broad and powerful effect on metabolism. Its normal function is an important condition to ensure human health. For example, diabetes is a common disease that is closely related to dysfunction of insulin. Some people estimate that there are more than 200 million diabetic patients in the world, more than 10 million diabetic patients in the United States, the incidence rate is as high as 5%, even as high as 50% in some areas and the incidence of diabetes in our country may be lower. According to “Practical Internal Medicine” ) Is estimated to be less than 1%. However, with the improvement of medical and health conditions in our country, the average life expectancy and the improvement of the diagnosis level, it is estimated that the number of diabetic patients found in the future will increase. Therefore, diabetes in our country is also a problem that deserves attention. The chemical nature of insulin is protein. “Life is the way the body of the protein exists” (Engels). the study
