Abstract: Different doses of lead nitrate (1,2,4,8 mg Pb穔g-1 body weight) were applied to the adult Bufo bufo gargarizans.7 days after treatment,using vertical polyacrylamide gel electrophoresis,the effects of lead on the peroxidase isozymes and esterase isozymes in liver and kidney were studied.The results showed that the activites of peroxidase isozymes in liver and kidney were changed greatly at different concentrations of lead treatment groups.The effects of lead on esterase isozymes in liver and kidney varied with tissues,which indicated the organisms stress.It means lower dosage lead may induce esterase isozymes and improve its enzyme activity in a certain range.
