Effects of training on the extent of experimental myocardial infarction in aging rats.

چکیده
The effects of exercise on the severity of isoproterenol-induced myocardial infarction were studied in female albino rats of 20,40,60 and 80 weeks of age. The rats were trained to swim for a specific duration and for a particular period. The occurrence of infarcts were confirmed by histological methods. Elevations in the serum GOT and GPT were maximum in the sedentary-isoproterenols and minimum in the exercise-controls. These changes in the serum transaminases were associated with corresponding depletions in the cardiac GOT and GPT. However, age was seen to interfere with the responses exhibited by the young and old rats. Studies dealing with myocardial infarction are more informative when dealt with age.

Aims Activation of inflammatory processes is necessary immediately after myocardial infarction (MI), but if it continues excessively, it can facilitate the occurrence of MI. Considering the positive effects of exercise on inflammatory pathways and their reduction, it seems to play a crucial role in improving the condition of MI patients. Accordingly, the present study investigated the effect of...

متن کاملEffect of six weeks low intensity interval training on expression of atrial and brain natriuretic peptide genes following myocardial infarction in rat
Background: Myocardial infarction (MI) is the irreversible cell death caused by ischemia in parts of myocardium. Atrial and Brain natriuretic peptides (ANP and BNP) are known as strong markers of myocardial infarction. This study was aimed to evaluate the effect of six weeks low intensity interval training on ANP and BNP genes expression in rats following myocardial infarction. Materials and m...
