Objective To investigate the expressions of endothelin 1(ET 1) and endothelin converting enzyme (ECE) mRNA in bronchial mucosal biopsis from asthmatics, and the effect of inhaled corticosteroids on the expressions of ET 1 and ECE genes.
目的探讨内皮素1（ET－1）和内皮素转化酶（ECE）mRNA在哮喘气道粘膜的表达，以及吸入激素对其表达的影响。
Open lung biopsis was carried in 47 cases of congenital heart defect with pulmonary hypertension, the amount of pulmonary arteriole were calculated, and compared with the early result of operation and Heath Edwards classification in pathology.
对47例先天性心脏病并肺动脉高压症患者作术中肺活检，并对肺切片中单位面积小动脉数量与术后早期结果作比较：发现肺动脉高压症患者单位面积肺小动脉数量明显下降，并且与Heath?Edwards肺血管病理定性分级的轻、重程度有关；
