Blood-brain barrier permeability during acute and chronic electroconvulsive seizures.

Abstract

The effect of chronic electroconvulsive seizure on the blood brain barrier permeability to albumin was investigated in the male rats. Evans blue was used as a blood brain barrier tracer. The following situations were studied: Acute electroshock: a. one electroshock stimulus, b. ten electroshock stimuli. Chronic electroshock: a) group of animals were pretreated with electroshock given as one electroshock (ES) every other day (ES x 7); b) chronic electroshock + one electroshock, c) chronic electroshock + ten repeated electroshocks. As a result, chronic electroshock per se does not effect the blood-brain barrier permeability.
