RESUMO
Effect of feeding safflower oil and coconut oil in experimental myocardial infarction induced by isoproterenol in rats was studied. Based on the survival rate and histopathological examination, safflower oil was found to offer better protection than coconut oil. Serum GOT levels also confirmed the protective activity of safflower oil. The concentrations of cholesterol and triglycerides in the heart and aorta were lower in the safflower oil fed group, while the level of phospholipids was higher.

Effect of ethanol administration on the severity of myocardial infarction induced by isoproterenol in rats was studied. Even though serum CPK and GOT levels as well as the extent of myocardial damage as revealed by histopathological studies, were similar, the survival rate was higher in rats administered ethanol. Concentration of cholesterol and triglycerides in the serum and heart in rats given ethanol and isoproterenol seems to be the additive effect caused individually by ethanol and isoproterenol. Myocardial alcohol dehydrogenase and aldehyde dehydrogenase both showed increased activity in rats treated with ethanol. The rate of recovery from myocardial infarction however, was slower in rats treated with ethanol as judged from the serum CPK value.
