Twenty-four subjects with positive propagated sensation along the channels (PSC) above elbow and/or knee including five subjects with marked PSC, were studied with rheography, electrocardiography, urinary volume and 3'5'-cAMP determinations. Electro-pulse-stimulator was used to elicit PS by stimulation of Jing (well) point. Rheography was done with electrodes on the points of Jiexi and Zusanli of the Stomach Channel of Foot-Yangming. The signals were introduced into ECG machine and recorded in lead II. There were 19 individuals with positive PS along the Stomach Channel in the tested group and 18 negatives as controls. Changes in the systolic wave amplitude and index of peripheral resistance on the rheogram were studied during the process of sensory propagation along the Stomach Channel. These were found to be significantly increased when the PS passed to the points of Jiexi and Zusanli with continuous stimulation for 5 minutes as during its regression. Ten minutes after the stimulation, they were restored to the basal level. The result shows that the rheogram on the line of Stomach Channel changes correspondingly with the dynamic process of PS, while no similar changes were observed in the controls. In four subjects with marked PSC the PS of the Pericardium, Kidney and Urinary Bladder Channels were studied. The experiment was done nine times, the heart rate was significantly changed during the PS of the Pericardium Channel. As the PS passed to the chest region, there were invariably transient increases in heart rate. The increment being from five to thirty-two per minute. The heart rate dropped back to previous level when the PS was over. In our studies the PSC of the Stomach and Large Intestine also crossed the chest region, but no changes in heart rate were noticed. Taking the urinary volume and 3'5'-cAMP as parameters for observation, we found that one to three hours after the stimulation of the Kidney and Urinary Bladder Channels after PS was obtained, there was an obviously peak output of the hourly urinary volume. In three subjects, there were also transient peaks in urinary 3'5'-cAMP excretion, but in one case the change was irregular. On the contrary, when the PS of the Spleen and Stomach Channels were elicited under the same condition, there were no transient peaks in both of the urinary parameters. The 24-hour urinary volume and 3'5'-cAMP excretion were also much less. A case of marked PSC person was followed one year postoperatively, the phenomenon of PS has disappeared. After stimulation of the Kidney and Urinary Bladder Channels, the urinary volume and 3'5'-cAMP were not much changed. The experiment shows that changes in heart rate, urinary volume and 3'5'-cAMP induced by PS along of the Channels of Pericardium, Kidney and Urinary Bladder are specific and will be altered with the dynamic process of the sensory conduction. Our work shows that during the sensory conduction process, there are specific changes along the sensory conduction lines and in the corresponding viscera. To a certain extent, the above mentioned three parameters may objectively reflect the dynamic changes in the process of PSC. Hence, they are of definite significance in the study of the phenomenon of PSC.
