[ATPase activity in neurons and neuroglia during convulsions induced by picrotoxin]

Na+,K(+)-ATPase activity was studied in neurones and neuroglia under conditions of convulsions caused by picrotoxin administration. Picrotoxin is a stimulant which causes convulsions by suppression of presynaptic inhibition. Na+,K(+)-ATPase activity in neuroglia was increased in convulsion, bat was not altered in neurones. It is possible, that glial Na+, K(+)-ATPase activity plays the role of neuronal ion's flows regulator and neuronal protector from convulsions. In recovery period ATPase activities in neuronal and neuroglial cells run up to control.
