The asymmetrical breakdown of the blood-brain barrier to Evans-blue was studied in male and female rats during epileptiform seizures and in acute hypertension. The animals were divided into six groups. Group I: control female; Group II: control male; Group III: female + acute hypertension; Group IV: male + acute hypertension; Group V: female + seizure; Group VI: male + seizure. Asymmetric breakdown of the blood-brain barrier had been seen in female rats treated with pentylenetetrazol. Pentylenetetrazol-induced seizure produces less disruption of the blood-brain barrier in right cerebral hemisphere than in left cerebral hemisphere in female rats. There were no asymmetrical changes of blood-brain barrier;permeability between the left and right hemispheres in acute hypertension in both sexes, and male rats treated with pentylenetetrazol.
