The experiments upon human subjects verified the results secured in the experiments upon animals. The first series of experiments upon human subjects were planned to determine the effect of stimulation, inhibition, and and artificial lesion upon systemic blood pressure. It should be remembered that the experiments upon animals indicated the following facts: The artificial lesion in the splanchnic area causes a dilatation of the intestinal vessels, a lowering of the systemic blood pressure, a relaxation of the gastric and intestinal walls, and the accumulation of gas in the stomach and intestines. Mechanical inhibition in the same area produces the same results in less marked degree. Mechanical stimulation in the splanchnic area causes increased peristalsis, decreased caliber of the blood vessels, increased systemic blood pressure, and the absorption of whatever gas may be present in the stomach and intestines. Mechanical stimulation of the tissues near the thirteenth and fourteenth vertebrae causes a rise of blood pressure and a contraction of the arterioles in many parts of the body, and an increased heart action, by the effects of the increased action of the supra-renal capsules. It is needless to say that these experiments could not be repeated upon human beings. But equivalent results were secured by use of harmless methods. The first series of experiments upon human subjects were devoted to the determination of the effects of stimulation, inhibition, and the artificial lesion upon blood pressure. The subject was permitted to rest quietly upon a treating table until the pulse displayed no...
