The 21-aminosteroid U-74389G protects the antioxidant enzymes in the ischemia/reperfusion-induced rat brain damage.
The antioxidant enzymatic system in the ischemia/reperfusion induced brain injury in rats after U-74389G administration was evaluated. Ischemia/reperfusion caused a decrease in the activities of superoxide dismutase and glutathione reductase, as well as of total and free sulfhydryl groups, while thiobarbituric acid-reactive substances became elevated. Administration of U-74389G lead to restoring to normal values of all above parameters. Protective effect of the drug in ischemia/reperfusion induced brain injury has been suggested.
