ABSTRACT
Objective To observe the effect of PM2.5 on the secretion of NO, ET-1 and the proliferation of rat vascular smooth muscle cell(VSMC) in vitro.Methods VSMCs were treated with PM2.5 collected from urban area of Zhanjiang,at the doses of 10,20,50,100 and 200 ?g/ml.After 24 hours of treatment, the levels of NO and ET-1 in the VSMCs were detected by nitrate reductase method and radioimmunoassay respectively, the proliferation of VSMCs was detected by MTT.Results At the concentrations of 10-200 ?g/ml, with PM2.5 increased, the level of NO in VSMCs decreased from(43.53 ?3.46)?mol/L to(29.28?2.28)?mol/L(F=18.89,P
