Myocardial constitutive and inducible nitric oxide (NO) synthase activities were measured in right ventricular tissue from 17 patients with dilated cardiomyopathy (DCM). A significant activity of inducible enzyme was accompanied by a low activity of the constitutive NO synthase. Thus, the myocardium has the capacity to express both NO synthases. NO may have a physiological as well as a pathological role in the human myocardium.
在17例扩张型心肌病(DCM)患者的右心室组织中检测了心肌组成型和诱导型一氧化氮(NO)合酶活性。诱导型酶的活性显著,同时组成型NO合酶的活性较低。因此,心肌具有表达两种NO合酶的能力。NO在人类心肌中可能具有生理和病理作用。
