    Abstract:
    Low-molecular weight peptides prepared according to an original procedure from a cattle heart possess a protecting effect on the myocardium during ischemia. Peptides in doses of 10(-7) g/ml and less improve the indexes of contractility function of the isolated heart after total ischemia and correct respiration warranting cardiomyocytes survival during hypoxia. However, in different models high doses of heart peptides (5 x 10(-6) g/ml and more) are shown to inhibit contractility, to stop respiration, the action of the peptides increasing with myocardial ischemia degree.
