【摘要】 本文通过测定200例不吸烟及80倒吸烟的健康大学生血清α₁-抗胰蛋白酶抑制活力来探讨大学生吸烟的危害性。以期引起学生、家长、学校各方面的重视，协同控制吸烟，降低烟害诱发的肺气肿，慢性阻塞性肺炎及肺癌的发病率。用改良Anksarxl法以苯甲酰-DL-精氨酸对硝基苯胶为底物测得不吸烟与吸烟大学生血清α₁抗胰蛋白抑制活力结果分别为1．12±10．10mg/mlt1.47±0.12mg/ml和1．17±0．12mg/ml.本法简便、省时、结果可靠，适宜于基层实验室掌握推广。更多还原

【Abstract】 The ds tried to foruss tha bo dri of hang by determination of serum - ATinhibtory capacity in 2（X） no- and 80 smoking healthy college studens in an attempt to cause theattenhon of the studnts, pe bo ha conuntalties’ ch to reduce the incidence of emphysemapdrinary, chronic obstractive pneumonia and lung cancer for by smoking. Taking Benzoyl - DL - argiain-P - nitranilid as substrate , the improved the Eriksson’s method was developed for the detenmination of the serum α₁-AT inhbitory capacity. The results showed that the serum - AT inhibitory capacity of edng andsmoking college students were 1. 12 O. 10mg/ml and 1. 17 1 0. 12mg/ml. The method was simple , rapid,reliable and and was suitable for popularization in basic laboratories.更多还原
