Objective To investigate the effects of nitrogen monoxide (NO),nitricoxide synthase(NOS),constitutive NOS (cNOS) and inducing NOS (iNOS) on myocardial ischemic reperfusion injyry in rat models following electroacupuncture to Neiguan. Methods 50 Wistar male rats were randomly divided into five groups,i.e. sham operated group(SOG), modeling group(MG), Neiguan electroacupuncturing group(NEG), Lieque-electroacupuncturing group(LEG) and Hegu-electroacupuncturing group(HEG),with 10 rats in each group.Then,the changes in the activities of NO,NOS,cNOS and iNOS were determined and compared among the an...
