Microscopic emphysema in relation to age and smoking habit.
BACKGROUND The increases in airspace size within the human lung associated with microscopic emphysema can be assessed by measuring the airspace wall surface area per unit volume of lung tissue (AWUV). In a previous study the limits of normality of AWUV with age were estimated in lifelong non-smokers by the 95% prediction limits of the regression line for these variables. The aims of this study ...
متن کاملRelation of smoking and age to findings in lung parenchyma: a microscopic study.
A microscopic study was made to determine the relationship between various lung parenchymal changes, smoking habits and age. The subjects were 1,824 men and women for whom a macroscopic study of pulmonary emphysema has previously been reported. Lung parenchymal changes included rupture of alveolar septa (emphysema), fibrasis, and thickening of small arteries and arterioles. The mean degree of e...

SMOKING Association of CYP2A6 deletion polymorphism with smoking habit and development of pulmonary emphysema
Background: Nicotine is responsible for smoking dependence and is mainly metabolised by CYP2A6. Several types of genetic polymorphism of CYP2A6 have been reported, but their relation to smoking habit and chronic obstructive pulmonary disease (COPD) phenotypes has not been fully clarified. Methods: 203 current or ex-smokers (lifelong cigarette consumption (CC) >10 pack years) with subclinical an...
