Objective To investigate the cell cycle of airway smooth muscle cells(ASMC) in asthmatic rats with airway remodeling and to explore a new method for the prevention and treatment of asthma.Methods The asthmatic rat models were established.The pathologic changes of inner airway wall and ASMC were determined by observing and analyzing the lung tissue sections stained with HE,and the cell cycle distribution of ASMC were analyzed by flow cytometry.Results The inner airway wall and smooth muscle layer were much thicker in rats of asthma group than those of control group(P
