Abstract/OtherAbstract:
The changes of pulmonary arterial and pulmonary venous plasma endothelin (ET) level in oleic acid (OA)--induced lung injury (ALI) rats were observed. After the ALI model of rats was established by intravenous injection of OA, blood samples were taken from a right cardiac catheter inserted via the right external jugular vein into the pulmonary artery to determine the plasma ET levels by using radioimmunoassay before OA injection, and 2 h and 4 h after OA injection. At the same time, arterial oxygen pressure (PaO2) and mean pulmonary arterial pressure (mPAP) were measured to evaluate the role of ET in acute lung injury. The results showed that the plasma ET levels after OA injection were significantly increased in OA group rats as compared with those in the controls, positively correlated with mPAP and negatively with PaO2. The plasma ET level in pulmonary vein was higher than in pulmonary artery, but no significant difference was found. It was concluded that ET, as a local or circulating hormone, might play an important role in pathophysiology of ALI.
