title: [Changes of nitric oxide system during acute myocardial ischemic reperfusion].
abstract: The reciprocal changes of NOS and arginase activity during acute myocardial ischaemia (90 min) and reperfusion (180 min) was shown in experiments on chest-closed dogs with spontaneous breathing. NOS activity in the ischemia injured myocardial decreased on 60% while arginase activity increased on 487%. Levels of both alternative pathways of L-arginine metabolism altered reciprocally too. NO2(-)-level was reduced on 57%, and urea level increased on 665%. The same changes were in arterial blood, started from 10 min of ischemia. These changes can play an important role for development of acute ischaemia treatment.
