[Systemic and regional hemodynamics during audiogenic convulsions in rats genetically epilepsy-prone]

Changes in systemic and regional hemodynamic during sound-induced convulsions were measured with microsphere technique in genetically epilepsy-prone rats of Krushinsky-Molodkina (KM-rats) strain. Blood pressure increased from 103 till 178 mm Hg and cardiac index rose from 27.3 till 49.3 ml/min/100 g b. w. during convulsions. Blood flow was increased in the brain and in the heart by 140-700%, whereas in most of internal organs it was decreased by 40-94%.
