| Research Abstract |
The present study sought to ascertain the effects of erythropoietin(Epo) on pulmonary hypertension and right heart failure following extensive pulmonary resection. Rats were divided into three group:
(1)Group T, sham control comprising right thoracotomy only;(2)Group L, right three lobectomy;(3)Group EPO, right three lobectomy with subcutaneous administration of recombinant human Epo
We calculated diameter of right ventricular cardiomyocytes, weight ratio of the right ventricle to the left ventricle plus septum(RV/LV+S;). In these results, Epo significantly suppressed right ventricular hypertrophy. We calculated diameter of medial wall thickness of peripheral pulmonary arteries as an indicator of pulmonary hypertension. Epo also significantly su ppressed the medial wall thickness of peripheral pulmonary arteries.
