title: [Observation on the occurrence of lung cancer and changes of pulmonary bronchioles and arterioles in the smokers].
abstract: We studied 600 lung specimens microscopically. Among them, 362 were males, smokers accounted for 304 cases. 236 cases were lung carcinoma were found, 72% were smokers. Among the 236 cases, 110 cases of squamous carcinoma. The smokers were 6.8 times more than the nonsmokers, 22 cases were small cell carcinoma, the smokers were 4.4 times more than nonsmokers. 84 cases were as adenocarcinoma, the number of the smokers were as similar as that of nonsmokers. In cases with smoking history of less than 10 years, the thickness of arterioles wall were similar to that of nonsmokers. The thickness of arteriole wall increased as the duration of smoking history increased. (12%-22.4% in every 10 years).
