Abstract:
Objective To investigate the protective effect and possible mechanism of Decorin on pulmonary fibrosis.Methods A total of 90 healthy Wistar rats were randomly divided into three groups:group A served as control group,group B was injected BLMA5 through trachea,group C was injected BLMA5 and received treatment of Decorin.Ten rats in each group were killed 7、14、28 days after intratrachael instillation.TGF-?_1 expression was measured by immunohistochemical technique.The degree of alveolitis and fibrosis were measured by HE staining.The contents of hydroxideproline were measured in the homodenate of the rat lung.Results The expressions of TGF-?_1 were increased gradually in group B;in group C the expressions were decreased significantly than group B(P
