title: [Some properties of glial membrane Na, K-ATPase].
abstract: Na,K-ATPase activity in glial membranes is rather low that in the nerve ending membranes, but is characterized by the same kind of Na+/K+-dependence. Glial Na,K-ATPase is insensitive to acetylcholine (ACh), 5-hydroxytryptamine (5-HT) and gamma-aminobutyric acid (GABA) while norepinephrine activates Na,K-ATPase at low concentrations and inhibits it at high concentrations. Participation of Na,K-ATPase in the regulatory mechanisms of the neuron-neuroglia relations is discussed.
