Effect of Different Periods of Exposure to Passive Smoking on Internal Diameter and Thickness of Lung Arteriolesin Rabbit Oryctolagus cuniculus

In the present work, the effect of different periods of exposure to passive smoking on arterioles of rabbit lung were investigated. Results showed changes in internal diameter and wall thickness of arterioles when exposed to passive smoking at different periods. Decreasing in internal diameter and increasing in thickness of arterioles have been also demonstrated histologically and statisticaly.
