Activation of inflammation and enzyme cyclooxygenase with formation of proinflammatory prostaglandins is a key element of development of myocardial infarction in patients with acute coronary syndrome. Basing on literature data and own experience we suggested that single intravenous injection of 230 mg/kg of nonselective inhibitor of type 1 and 2 cyclooxygenase lornaxicam in the phase of initialization of inflammation 20 min after onset of ischemia would lead to reduction of myocardial infarction volume in rats in irreversible ischemia and ischemia with subsequent reperfusion. The conducted study allowed to reveal that administration of lornoxicam in recommended for human use dose lowered mortality of animals and increased number of capillaries per one cardiomyocyte in case of irreversible coronary artery occlusion. In ischemia-reperfusion as in irreversible myocardial ischemia lornoxicam reduced volume of necrosis and degree of thinning of left ventricular wall in the region of infarction, and lowered volume of connective tissue in periinfarction zone of the myocardium in remote period. |
