摘要
本文对健康人、矽肺病人及肺气肿患者各30例为对照进行血清弹性蛋白酶抑制力(SEIC)的研究。结果发现:①矽肺组病人测得SEIC值为114.4±4.3u/ml,与对照组121.2±4.7u/ml比较差异不显著,与国内报道的SEIC结果相似。②肺气肿组SEIC值90.4±36.9u/ml,明显低于对照128.9±29.4u/ml,且差异非常显著。认为90u/ml可做为SEIC的易肺气肿的界限值,将SEIC值低于90u/ml者列为肺气肿易患者。
A case-control study on Serum Elastase Inhibitory Capacity were investigated among 30 cases with silicosis 30 cases with pneumonectasia and a matching contral group.Results showed Serum Elastase inhibitory,Capacity levels were 114±4.3u/ml in patients with silicosis and 121.2±4.7u/ml in control grop.The difference was not significant.Serum Elastase inhibitory Capacity levels were 90.4±36.9u/ml in the patients with pneumonectasia,which was significantly lower than the control grop(Serum Elastase inhibitory Capacity lever=128.9±29.4u/ml).the distribution of Serum Elastase inhibitory Capacity levels was studied among the patients with pneumonectasia and the contral grop.The results showed that the serum Elastase inhibitory capacity 90u/ml was the limit with patcents suffered from pneumonectasis.
