The content of macro- and trace elements in the cardiac muscle of adult and old rats after stressor influence

Experiments with adults (8-10 months) and old (20-24 months) male rats have permitted establishing that the stress-induced damage caused an increase in the Ca, Na content and a decrease in the K, Mg, Cu, Zn, Fe content in the cardiac muscle of experimental animals. It is important that there are cer...

Summary:Experiments with adults (8-10 months) and old (20-24 months) male rats have permitted establishing that the stress-induced damage caused an increase in the Ca, Na content and a decrease in the K, Mg, Cu, Zn, Fe content in the cardiac muscle of experimental animals. It is important that there are certain peculiarities in changes in the heart of adult and old rats. Changes in the heart of adult animals after the stress were similar to age changes in control old animals. This confirms the V. V. Frol'kis opinion about the development of the stress-age-syndrome in old animals. The stress-induced damage causes more important changes in the content of macro- and microelements in the heart of old rats.
