Study on the Change Tendency of SOD Activity in Wistar Rats and Kunming Mice after dietary Aflatoxin B₁ and Ge-132

In order to investigate AFB,metabolic pathway in vivo and relationship between Ge-132 and the free radical,the SOD activity in Wistar rats and Kunming maces which had been intaken AFB₁ and Ge-132 before and after were determined.The results showed that the changing tendency of SOD in rats and maces was similar.AFB₁could signficantly reduce the SOD activity in red blood cell,serum and liver tissue.The SOD activity both in rats and mites was stimulated after intaken Ge-132.Inhibitory of the SOD activity by single injection AFB₁ graduated away at last.Wistar rats were more sensitive to AFB₁ than Kunming mites.
