The effect of preliminary administration of alpha-tocopherol acetate (1 mg/kg) and sodium selenite (1 mg/kg) on RNA synthesis rate and changes in the macroergic content in ischemic myocardium was studied. It was shown to be conducive to ATP level maintenance after 30- and 60-minute heart ischemia. A statistically significant accumulation of RNA by the(More)
Two series of experiments were conducted to assess the potential of artificial ventricular bypass in restoring cardiac activity. One series evaluated use of a paracorporeal left ventricle in 17 calves; the other evaluated biventricular bypass in 11 calves. Module pumps with a seamless blood chamber of polyurethane were used.
