Abstract：Aim To investigate the changes of plasticity and distribution in the lungs of asthmatic guinea pigs.Methods Guinea pigs were divided into asthma group and control group.Immunohistochemistry was used in this study to observe the changes of ERK1/2 and Elk phosphoryiation in the lungs of guinea pigs.Results There were significant changes in distribution of EPK1/2 and Elk in the lungs of asthma group.The positive cells were detected on the walls of respiratory bronchioles and alveolar ducts,especially on the smooth muscle layer and basement membrane.In addition,the numbers of positive cell were clearly increased in asthma group(P< 0.01). Conclusion There is close relationship between the EPK1/2 and Elk phosphoryiation and attack of asthma.It may be a reason for persistence and progress of asthma.
