[The capacitive function of the spleen during electrical stimulation of the structures of the ventral section of the medulla oblongata].
In acute experiments on cats under perfusion with constant blood expenditure of hemodynamically isolated spleen the authors studied the reactions of its vessels in the electrical stimulation of ventral brainstem. It was shown that the stimulation of the rostral zone of these structures increased vein outflow from the spleen. It was shown the deterioration of the parametres which characterize a capacitance function of the spleen by stimulation of a causal depressor zone of the brainstem by means of the current of threshold size and its increase by irritation of the brain structures with a 2 threshold current size. There have been made a supposition has been made about the participation of the pointed structures of the brain in the regulation of a vasomotion tonus of the spleen vessels.
