The most strong antioxidant of direct action turned out to be DP, DECC exhibited the antioxidative properties as a result of metabolic activity in monooxygenases system of rat liver microsomes. Levamisole and labinzarit turned out to be weak antioxidants. The control of microsomal membrane stability against Fe(2+)-ADP, NADPH-induced LPO, after being isolated from rat liver after the action of CCl4 without and with DECC, showed that DECC protected microsomal membranes from CCl4 in vivo and they remained stable against LPO in vitro.</p>","PeriodicalId":18920,"journal":{"name":"Nauchnye doklady vysshei shkoly.
