用放射免疫(RIA)分析法测定国产封闭式舰艇人员血浆内皮素(ET)含量,并观察不同舰龄组间含量变化.结果表明,封闭式舰组ET含量比正常对照组低,不同舰龄组ET含量变化呈马鞍形分布曲线,1～2年组含量最低,>3年组明显回升,但仍比正常对照组低.由此提示,在国产封闭式舰艇上长期工作人员,不会因空气循环系统等原因引起血浆ET含量升高.
Radioimmunoassay (RIA) was used to determine the content of endothelin (ET) in Chinese-made closed naval ships and the content of endothelin was observed.The results showed that the content of ET in the closed warship was lower than that of the normal control group The change of ET content in the group showed a saddle-shaped distribution curve, with the lowest level in 1 ~ 2 years and the lowest level in> 3 years, but still lower than the normal control group, suggesting that long-term staff in domestic closed vessels would not be affected by Air circulation system and other causes of plasma ET content increased.
