BIOCHEMICAL ASPECTS OF PENTYLENETETRAZOLE INDUCED SEIZURE

Abstract

At the onset of pentylenetetrazole induced convulsions, the adenylate cyclase activity and phosphodiesterase activity were increased. The former was markedly stimulated in the brain stem of rats. In the cerebral cortex and brain stem, the glucose level was significantly decreased, and the concentration of Alucose-6-phosphate was increased. However, the definite changes in energy reserve system of the brain could not be observed at the onset of penetylentetrazole induced seizures. The present study revealed some correlation between pentylenetetrazole convulsions and the adenylate cyclase activity and glycometabolism.
