Abstract: This paper is to try to find out the significance and effect to apply the analytic
method of SOD isozymes to mammalian taxonomy by polyacrylamide gel eloctrophoresisof the isozymes in the tissues of bats and the erythrocytes of murids． The obtainedresults show that SOD isozyme is a veryuseful tool enzyme to distinguish new speciesor evolution of mammal，because there are marked differences of the mobility， thecomposition and the distribution of SOD isozymes in different species．But there are notnotable differences about above-mentioned characteristics of SOD isozyrnes in differentindividual of same species and in different tissue of same individual．The resultssuggest that it would be not necessity to emphasize the number of animal analysed andnot necessity to analyse every tissues． It is very good to make research on proteinbiochemical types of rare mammals，because they are very scarce and not killed in order
to draw materials．
