[Alteration of the ATP-ase Mg++ and Mg++ Na+ K+ activities of the central nervous system of Periplaneta americana L. after sonification. (author's transl].
A prolonged ultrasonic homogenization of a Periplaneta americana L. suspension of ganglia in a buffer solution pH 7,6 when compared with a Potter Elvehjem homogenization shows a marked reduction of Mg++ and (Mg++ + Na+ + K+) ATPase activities. Mg++ ATPase was not modified while the (Mg++ + Na+ + K+) ATPase was completely inhibited after 30 second ultrasonic homogenization. This probably results from an enzyme structure alteration caused by the ultrasonic treatment.
