[Effect of atenolol, dibunol, peroxidase and Astragalus dasynthus on the morphometric parameters of myocardial infarction].

Experiments were carried out on rats after coronary arterial ligation. In the myocardial infarction region there is the border zone or reversibly damaged zone which may be partially saved from necrosis by using beta-blocking agents. Atenolol, dibunol, Astragalus dasyanthus pall. moderately decrease the myocardial damage area at permanent and transient ischemia.
