Effects of puerarin on pulmonary vascular structure of chronic hypoxia in rats / 中国药理学通报

AIMTo investigate the effects of puerarin on pulmonary vascular structure in pulmonary hypertension rats induced by chronic hypoxia. METHODSThirty male spragu-dawley rats were randomly divided int o three groups:control group(NC), hypoxia group(HH), hypoxia+puerarin group(HP). Collagen Ⅰ, Ⅲ and collagen I mRNA were observed in pulmonary arterioles by th e technique of immunohistochemistry and in situ hybridization. RESULTS①mPAP was much higher in rats of HH group than that of NC group(P0 05). ②The contents of lung homoge nates SOD and MDA of HP group were obviously higher than those of HH group(P 0 05). CONCLUSIONPuerarin can improve pulmonary vessel remodeling.
