title: [Effect of nicotinamide on epileptic activity in the cerebral cortex].
abstract: The experiments on cats showed that intravenous administration of nicotinamide suppresses the epileptic activity in a solitary epileptic focus as well as in the complex of epileptic foci produced by strychnine application to various cortical zones under the influence of the most powerful focus that plays the role of a determinant. After the intravenous injection of nicotinamide (50-70 mg/kg) the complex was destabilized and broken down. The epileptic activity in the dependent foci of the complex disappeared first in the more remote from the determinant focus and then in the nearer one. The determinant focus was the last to disappear. The inhibitory effect of nicotinamide is associated with antiepileptic activity. Nicotinamide is suggested to be one of the endogenous drugs which may suppress brain hyperactivity and activate the antiepileptogenic system.
