title: [Relationship between central and peripheral mechanisms in regulating capacitance vessels].
abstract: In acute experiments on cats, responses of the resistance and capacitance vessels of the spleen and hindlimbs to local electric stimulation of the medulla oblongata, of the sympathetic nerves, and pressor reflexes during different pressure of the venous outflow, were studied. No structures were revealed which could selectively affect the capacitance vessels. The bulbar structures affected both the resistance and the capacitance vessels. The reflex responses aof the pre- and post-capillary portions of the vascular bed could be different, the transmural pressure being one of the factors for dilatory responses of the capacitance vessels. The different responses of the capacitance vessels could occur on account of both local and central mechanisms, their participation, however, being unequal.
