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。
In this paper, healthy volunteers, patients with silicosis and patients with emphysema in each 30 cases as a control serum elastase inhibition (SEIC) study. The results showed that: ① The SEIC value of silicosis patients was 114.4 ± 4.3u / ml, which was not significantly different from 121.2 ± 4.7u / ml in control group, which was similar to the SEIC results reported in China. ② The SEIC of emphysema group was 90.4 ± 36.9u / ml, which was significantly lower than that of control group (128.9 ± 29.4u / ml), and the difference was significant. That 90u / ml can be used as the limit of SEIC easy emphysema, SEIC values below 90u / ml were classified as emphysema patients.
