Abstract:	The effect of cigarette smoking and essential oil of Juniperus communis of tracheal contraction and dilatation was studied in 40 female Spraque-Dawley rats. The animals (rats) that were used for analysis were divided into four lots: smoking, non-smoking, exposed and not exposed to juniper oil. The smoking lot was exposed to 2 cigarettes per day, 5 days a week for 6 weeks. Then, the rats belonging to lots 2 and 4 were exposed to juniper berries oil for 3 weeks, 20 minutes per day. The control lot (lot 1) was not exposed to cigarette smoke. In this study we also performed physiological analyses for trachea and lung of experimental rats. Histopathological studies present the effect of cigarette smoke and Juniperus communis oil for trachea and lung. Physiological studies were performed upon analysis of bronhodilator and bronhoconstrictor trachea effects.
