UIe effects of propranolol and atenolol on free radical mediated injury in myocytes were examined. Freshly isolated adult canine myocytes were incubated with a superoxide generating (from dihydroxyfumarate) and Fe-catalyzed free radical system. Exposure of the myocytes to free radicals for 20 min resulted in more than a 5-fold increase in thiobarbituric acid reactant (peroxide) formation and elevated levels of lactate dehydrogenase (LDH) activity released into the media compared to controls… CONTINUE READING
