It has been known for along time that weak stimulation of the afferent somatic nerve causes depressor responses, but as the stimulation is intestified, pressor responses appear. There are papers by Johason as well as by Sato on these phenomena, in recent years. It has been revealed in the experimental studies on anesthetized dogs made in author s laboratory that afferent somatic nerve stimulation of the forelimbs gives predominantly pressor responses, and of the hindlimbs predominantly depressor responses. In this study, afferent stimulation of the somatic nerves were applied on anesthetized depressor responses, namely, observing the blood pressure, heart rate and cardiac output, terms of the effects of artificial pacing, section of the vagus nerve, atropine treatment, propranolol treatment and treatment with ganglion blocking agent. Analyzing the mechanism of blood pressure responses from the aspect of hemodynamics, the author came to the conclusion that the blood pressure responses are, in most part, attributable to dilation and contraction of the resistant blood vessels.
