Hot-spring bath, dry heat bath, instilation of hot-spring, plain 45 rabwater and 5% saline solution into the duodenum were tried in the total of bits and the effect of these preparations on the motility of small and large intestines were studied by the use of electromyography. The hotsprings used in the present study were of Narugo Branch Hospital and of Narugo National Hospital.
The results obtained are summarized as follows:
1) In the group of rabbits with hot-spring bath preparation, both the duration of each spike-bursts and the interval between the adjoining two sets of spike-bursts prolonged as long as 30 minutes after bathing.
On the other hand, dry heat bath (41°C) resulted in the reduction of both duration and interval of the spike-bursts during and immediately after the dry heat bath and gradually they tended to return to the control levels in 10 minutes. In these experiments, electromyograms taken from the small and large intestines were almost the same in findings.
It is concluded that the both hot-spring bath and dry heat bath lead to the excitement of intestinal motor function and the former has the stronger effect than the latter. The dry heat bath elicites an increase in the motor function of the intestines during and immediately after the dry heat bath, while the hot-spring bath causes an increase in the intestinal motility lasting approximately 30 minutes. These findings may have some relationship to the chill or warm sensation after bathing.
2) Instilation of the hot-spring, either of Narugo Branch Hospital or of Narugo National Hospital, plain water and five per cent saline solution at the temperature of between 40°-41°C into the duodenum failed to cause any noticeable changes of electromyographic findings such as of duration or interval of the spike-bursts. Therefore, it was learned that the instilation of these four kinds of solution had little effect on the motor function of the duodenum.
Out of these findings, it is estimated that the hot-spring bath which increases the motor function of the intestines has a considerable significance in its clinical application. Oral administration of the hot-spring, however, seems to have little effect on the motor function of the duodenum.
