ABSTRACT
Objective To examine the expression of typeⅠcollagen in pulmonary arteries of rats with monocrotaline(MCT)-induced pulmonary hypertension(PH) and explore the mechanism of pulmonary vascular structural remodeling.Methods Twelve male Wistar rats were randomly divided into 2 groups the MCT group(n=6) and the control group(n=6),which received a single intraperitoneal injection of MCT solution(60 mg?kg-1,the first day) or 9 g?L-1saline,respectively.After 3 weeks,mean of pulmonary artery pressure(mPAP),the value of right ventricle/(left ventricle plus septum)[RV/(LV+S)] and body weight were measured.Lung sections(HE stained) were observed under lightmicroscope for changes of the pulmonary arteries.The protein expression of typeⅠcollagen in pulmonary arteries was detected by immunohistochemical technique.Results Three weeks after MCT injection,compared with control group,mPAP and RV/(LV+S) increased significantly in MCT group[mPAP(10.60?2.06) mmHg(1 mmHg=0.133 kPa) vs(32.40?3.24) mmHg,P
