The effect of acute and chronic ethanol administration on rat brain superoxide dismutase (SOD) activity was studied. Intraperitoneal injections of ethanol led to an inhibition of SOD activity. When ethanol was fed as the sole fluid, the SOD activity decreased progressively, reaching a plateau after 6 weeks of treatment. Withdrawal of ethanol produced a recovery of control values within 48 hr. SOD activity was also decreased in rats born from ethanol-drinking mothers. Inhibition of SOD activity by ethanol may allow an accumulation of cytotoxic O2 - radicals; this may account for some nervous system disorders during alcohol intoxication.
