[Effect of cerous nitrate on the activity of ATPase in tissues].
The effect of cerous nitrate on the activity of some ion-dependent ATPase such as Ca(2+)-ATPase, K+, Na(+)-ATPase and Mg(2+)-ATPase was studied in vivo. The results showed that Ca(2+)-ATPase, K+, Na(+)-ATPase and Mg(2+)-ATPase activity was increased in rat liver, kidney and heart after recurrent intraperitoneal administration of low dose of cerous nitrate(1 mg/kg), but no changes happened for these enzymes activity after high cerous nitrate administration(50 mg/kg). The mechanism of the phenomena was discussed.
