(1) Men who took a bath (of saline sodium bicarbonate hot spring) at 38°C for 15min. showed normalizations in the size, tonus and motion of their stomachs.
(2) By bathing in the above mentioned bath at 38°C for 30min. the amount of Mg2+, Cl-, Ca2+ in the blood varied and that of inorganic phosphate in the blood increased.
(3) Rats bathed were either in city water at 39°C for 15min. or 30min., in saline sodium bicarbonate hot spring (Shirahama hot spring) at 39°C for 15min. or 30min., or in sodium bicarbonate hot spring (Ryujin hot spring) at 39°C for 15min. or 30min.
There were remarkable differences in the quantity of electrolytes and inorganic phosphate in hypodermic connective tissue according to the duration of bath and the quality of the hot springwaters.
(4) By taking a bath in tap water or hot spring water the amount of electrolytes and minerals both in the blood and in the hypodermic connective tissue varied. The degree of variation differed by the character of waters and by the duration of bath.
This variation of the quantity of electrolytes and minerals in the blood possibly caused the change in the shape, the tension, and the motion of the stomach, and then normalize.
By these experiments the anthor could explain a part of the effects of hot spring bath.
