초록

This study was carried out to demonstrate the effects of oral administration of DA-8159. a selective phosphodiesterase 5 inhibitor. on development of pulmonary hypertension induced by monocrotaline (MCT). MCT-treated rats(60mg/kg) were divided into three groups and orally administered vehicle, 1 mg/kg or 5 mg/kgg of DA-8159 twice a day for 3 weeks. Increased right ventricular weights, medial wall thickening in pulmonary arteries. myocardial fibrosis, decrease of plasma cyclic guanosine monophosphate (cGMP) level and body weight gains were shown in MCT group.
