摘要
目的：探讨周围动脉粥样硬化闭塞症（ｐｅｒｉｐｈｅｒａｌａｔｈｅｒｏｓｃｌｅｒｏｓｉｓｏｂｌｉｔｅｒａｎｓ，ＰＡＳＯ）胰岛素抵抗（Ｉｎｓｕｌｉｎｒｅｓｉｓｔａｎｃｅ，ＩＲ）、内皮素（Ｅｎｄｏｔｈｅｌｉｎｓ，ＥＴ）、血管紧张素－Ⅱ（ａｎｇｉｏｔｅｎｓｉｏｎ－Ⅱ，ＡＴ－Ⅱ）之间的相互关系。方法：采用特异性葡萄糖氧化酶法和放射免疫测定法对５１例ＰＡＳＯ患者进行糖耐量实验前后血糖、胰岛素（Ｉｎｓｕｌｉｎ，ＩＮ）水平的测定，并计算其曲线下面积，同时采用放射免疫测定法检测血浆ＡＴ－Ⅱ和ＥＴ水平，并分别与ＩＮ及其曲线下面积作相关分析。结果：ＰＡＳＯ患者ＩＮ、ＥＴ、ＡＴ－Ⅱ水平分别为１４．７９ｍＵ／Ｌ、７７．６９ｎｇ／Ｌ、１１１．３３ｎｇ／Ｌ，明显高于健康对照组；同时糖负荷后１ｈＩＮ及其分泌总量明显增高；糖耐量实验前后ＩＮ水平及其曲线下面积均与ＡＴ－Ⅱ、ＥＴ呈正相关系。结论：老年ＰＡＳＯ患者存在ＩＲ现象，血管ＡＴ－Ⅱ、ＥＴ与ＩＲ之间相互影响、相互促进、共同参与ＰＡＳＯ的形成和发展。
Objective:To investigate the relationship between insulin resistance and angiotensin Ⅱ,and endothelins in aged patients with peripheral atherosclerosis obliterans(ASO).Methods:The blood glucose,insulin,endothelins and angiotensin were determined by methods of special glucose oxidated enzyme and radioimmunoassay.Results:The ASO patients had high levels of insulin,endothelins and angiotensin Ⅱ,higher insulin concentration at 1 hour postload glucose than in healthy controls.The insulin levels of these patients were significantly positively correlated with the levels of endothelins and angiotensin Ⅱ.Conclusion:The insulin resistance in the ASO patients was related to the levels of endothelins and angiotensin Ⅱ.It was suggested that the insulin resistance,endothelins and angiotensin Ⅱ influenced each other,and took part in the development of peripheral atherosclerosis obliterans.
