Abstract
Cellular (=total homogenate) and subcellular fractions (P1a-pellet, cy tosolic fraction SN3, P4-pellet, P8-pellet, synaptosomal and synaptic membrane fraction) of brain tissue of the cichlid fish Oreochromis mos sambicus and the Djungarian dwarf hamster Phodopus sungorus were colle cted and the distribution of creatine kinase (CK) and different Ca2+-M g2+-ATPase activities in each fraction were studied. The data obtained from cellular as well as from subcellular fractions indicate less CK, Ca2+- and (Ca2+-Mg2+)-ATPase activities in cichlid fish than in hamst er brain. The dwarf hamster expressed higher enzyme activity in the br ain as compared to the cichlid fish only in regard to the Mg2+-ATPase activity and with the exception of synaptic membranes.
