1型糖尿病微血管并发症血浆内皮素和心钠素的变化

目的 :阐明微血管并发症血浆内皮素和心钠素的变化关系。方法 :应用放免分析法 ,测定 31例1型糖尿病患者及 2 5例正常健康者血浆内皮素和心钠素水平。结果 :糖尿病患者血浆内皮素和心钠素水平均较正常者明显增高 ;伴微血管并发症者血浆内皮素和心钠素水平较不伴微血管并发症者增高 ;随着微血管并发症的增多 ,血浆内皮素和心钠素随之增高 ,而且内皮素与心钠素呈高度正相关。结论 :血浆内皮素和心钠素与 1型糖尿病的发生发展和病情的严重程度有关。

Changes in plasma endothelin-1 and atrial natrinretic factor in microvascular complication of IDDM

Objective:To investigate the changes in plasma ET-1 and ANF in IDDM and its microvascular complication.Methods:The plasma levels of ET-1 and ANF were measured by radioimmunoassy in 31 patients with IDDM and 25 normal controls.Results:The plasma levels of ET-1 and ANF significantly increased in IDDM compared with the normal controls (P<0.01);and the levels were also markedly higher in diabetics with microangiopathy complications than in those withou the complications (P<0.01).The more kinds of microangiopathey complications,the higher level of the plasma ET-1 and ANF,which suggests that the elevation of plasma ET-1 and ANF may be concerned with the microangiopathy and ET-1 may reflect the degree of vascular endothelial cell damage.There were no significant correlation between plasma ET-1 or ANF and blood glucose,fructosamine and C-peptide,but the plasma levels of ET-1 and ANF both correlated with the duration of diabetes mellitus.And the plasma level of ET-1 positively correlated with ANF1 (P<0.01).Conclusion:The results of study suggest that ET-1 and ANF are both associated with the development,progress and severity of microvascular complications.
