  • Title: [Effect of drugs on the resistance of the myocardium to hypoxia].
    Author: Spasov AA.
    Journal: Biull Eksp Biol Med; 1988 Jan; 105(1):110-2. PubMed ID: 3337872.
    Abstract:
    A method for the investigation of drug effects in the myocardium resistance to hypoxia has been suggested. It is based on the determination of drug effects on the performance of the isolated spontaneously contracting atrium (ISCA) of rats under hypoxic conditions. Hypoxia was induced by oxygen displacement from the nutritional solution by nitrogen. ISCA resistance to hypoxia was assessed by the mechanogram of the heart preparation (the duration and volume of ISCA performance being up to 50% of the initial amplitude). Using the inhibitor analysis, it has been demonstrated that the given model of myocardial hypoxia adequately reflects the role of energy cellular metabolism in the regulation of ISCA resistance to hypoxia and can be used in the search for myocardial antihypoxic agents.
