title: [Effects of ginkgolide B on isobaric hypoxic pulmonary hypertension in rats].
abstract: We examined the effects of ginkgolide B (BN52021), a specific platelet activating factor (PAF) antagonist, on hypoxia-induced pulmonary hypertension and pulmonary vascular remodeling. Chronic hypoxia can cause pulmonary hypertension and pulmonary vascular remodeling in rats. Treated with BN52021, the rat's pulmonary hypertension, pulmonary vascular remodeling and right ventricular hypertrophy at 3 weeks of hypoxic exposure (FiO2 = 0,10) could be reduced. The results suggest that PAF contributes to the development of chronic hypoxic pulmonary hypertension and pulmonary vascular remodeling, and PAF antagonist may be an useful agent for preventing hypoxic pulmonary hypertension.
