[Cytophotometric study of changes in glutamate dehydrogenase and GABA transaminase in the cerebral cortex during...

It has been demonstrated in (CBA X C57BL/6) F1 mice that daily corazole injections (30 mg/kg) lead to the development of pharmacological kindling that manifests in a progressive increase of seizure susceptibility, seizure occurrence in response to the subthreshold convulsant dose and in demonstrable seizures. Cytophotometric study of the histological specimens of the sensorimotor cortex discovered the reduced enzymatic activity of glutamate dehydrogenase and GABA transaminase in the neurons. In the neuroglial cells, the activity of glutamate dehydrogenase also declined, whereas that of GABA transaminase tended on the contrary, towards increase.
