Abstract

This study aimed to determine whether there was a difference in lung functions of smokers according to the presence of carcinogenic genetic-metabolizing enzymes by comparing the results of lung functions and the presence of genetic metabolizing enzymes that metabolize tobacco substances. To achieve this, 31 smokers without no illness and no psychiatric history were selected (28 males and 3 females); they were aged 20 to 27 years and were physically and mentally healthy students attending K University. Their lung functions were measured, and gene polymorphisms of cytochrome P-450 1A1 (CYP1A1) related to metabolic activation of tobacco components and gene polymorphism of tumor protein 53 (TP53) related to lung cancer were analyzed. As a result, the mean values of lung function of TT and Arg / Arg without genetic mutations were the highest, and ANOVA analysis of CYP1A1 and lung functions showed that the P-value of FVC was 0.049, which was different between groups. In other words, there is no high mutation in Cytochrome P-450 1A1 (CYP1A1) gene, which is associated with the metabolic activation of tobacco components. In other words, In the absence of the mutant Cytochrome P-450 1A1 (CYP1A1) gene, which is associated with the metabolic activation of tobacco components, the value of FVC was high.

흡연자들의 흡연 물질 대사효소의 유전적 다형성에 따른 폐기능의 차이를 보기 위하여 질병력과 정신과적 병력이 없는 신체적·정신적으로 건강한 만 20~27세 이하의 흡연자 31명( 남 29, 여 3)을 대상으로 연구를 진행하였다. 폐활량 측정기(Wright Respirometer, Ferraris Development and Engineering Co, Ltd, UK)를 이용하여, 노력성 폐활량(Forced vital capacity, FVC), 1초간 노력성 호기량(Forced expiratory volume at one second, FEV 1), 1초간 노력성 호기량의 노력성 폐활량에 대한 비(FEV1 % FVC)을 측정하였으며, 유전자 검사는 DNA로 PCR하여 CYP1A1과 TP53의 유전자 발현검사를 하였다. 실험결과 유전자 돌연변이형이 없는 TT와 Arg/Arg의 폐기능 평균값이 가장 높았으며, CYP1A1와 lung functions의 ANOVA 분석에서 FVC의 P-값이 0.049로 그룹 간의 차이가 있는 것으로 나타났다. 즉 담배성분의 대사 활성화와 연관이 많은 Cytochrome P-450 1A1 (CYP1A1) 유전자의 돌연변이형이 없을때 FVC의 값이 높게 나타난 것이다.
