The values of the skin impedance decreased strongly immediately after bathing and then increased and reached the maximum values about one-two hours after bathing at Tamagawa Hot-Spring. If the bathing was continued daily during about 2 weeks, the values of the skin impedance before bathing and one-two hours after bathing both decreased gradually day by day. In the case of fresh water bathing, the values of the skin impedance decreased remarkably immediately after bathing in the same way as bathing at Tamagawa Hot-Spring and then increased quickly and reached the maximum 30 minutes or one hour after bathing. If the bathing was continued daily during about 2 weeks, the values of the skin impedance before bathing decreased only slightly, but the values of the skin impedance later than 30 minutes-one hour after bathing showed a stronger increase over the values before bathing. In case of continuous bathing in a simple Hot-Spring, the values of the skin impedance before bathing showed no change every day, but the value later than one-two hours after bathing showed only a slight increase i. e. lower than the values before bathing. From these findings it is surmised that the decrease of the skin impedance immediately after bathing at Tamagawa Hot-Spring is caused by sweat excretion, and the decrease of that before and one-two hours after bathing, if bathing is continued daily at the same spring, is due to the cell infiltration at cutis and- corium and to the protoplasm activation of living body caused by stimulation of the denaturalized tissue substances produced by bathing dermatitis. The increasing values of the skin impedance 30 minutes-one hour after bathing in spite of almost no change before bathing every day in case of the continuous bathing method of fresh water is considered to be due to the contraction of capillary blood vessels or phenomenon of feeling chilly after a bath. The slight increase of the values of the skin impedance after 30 minutes-one hour after bathing in case of using the continuous bathing method of simple hot spring may be caused by continuance of dilatation of capillary blood vessels. The values of the skin impedance through contacting the electrode at skin surface was increased by injection of adrenalin and atropine, and decreased by injection of pilocarpine and ergotamine, but the values of the skin impedance through the mucous membrane of eyes i. e. through the electrode which was inserted into the physiological NaCl solution filled in the under water glasses contacted to both eyes showed almost no change owing to injection of all above mentioned drugs. From these findings it is considered that the skin impedance consists in the skin surface, and the decrease of its values is related to incline of the parasympatic nerve function and to the sympatic nerve function.
1) The serum Ch-E values in healthy children were indicated as follows: they were in the lowest level in new-horns, rose in sucklings, then gradually fell off and in primary-school age reached a level approximately equal to that in adults. 2) The values were found higher in suckings in the earlier half (up to 6 month of age) than in those in the later half (between 7 and 12 months). In particular, the babies aged one month showed the highest values. 3) No difference by sex could he observed in serum Ch-E values.
The serum Ch-E values were measured in child patients during the courses of their diseases, and the following results were obtained. 1) The values fell the further as the disease aggravated, but went up as convalescence progressed. 2) The values showed a very perceptible rise after spasmodic fits, as in epilepsy, ascariasis and ekiri. 3) Before death of tuberculous meningitis, miliary tuberculosis and such chronic consumptive diseases, the return Ch-E value falls below normal, but before death of acute diseases, such as acute bronchopneumonia, dyspeptic intoxication etc., the value rises considerably. 4) The lowest serum Ch-E value was observed in cases of tuberculous meningitis and highest in a cases of nephrosis. 5) As regards the changes in the clinical symptoms and the serum Ch-E values of the cases of acute infantile paralysis and cerebral palysy balneotherapy, I was led to infer a considerably close interrelation between hot-spring bathing and the serum Ch-E values.
The author prescribed experimental bathing in Genzo-yu and the Hot-spring of Narugo-Branch Hospital in the Tohoku University, all in Narugo Spa, Miyagi-ken, to study the effect of the bathing on the serum Ch-E values of children, as well as the bearing they have on the liver function, and arrived at the following conclusion: 1) The effect of once bathing on the serum Ch-E, values was most marked directly after the bath, falling in some cases and rising in others, thus revealing individual differences, but returned to the pre-bath values in 3 hours. The rise or fall was found widest upon bathing in Genzo-yu. No change was seen in the liver function before and after once bathing. 2) During continuous bathing, the serum Ch-E values decreased on the 3rd-7th but reincreased by the 14th day. This fluctuation of the values also was day the most manifest upon bathing in Genzo-yu. The change in the values ran parallel with anomalies appearing in the liver function. 3) The fluctuation of the serum Ch-E values following once bathing became narrowed down in scope by continuous bathing. 4) As symptoms of bathing reaction in children, accentuated 2nd pulmonary sounds, audible femoral sounds, a slight reduction of the serum Ch-E values and a very mild dysfunction of the liver were observed. All these were transient and could be attributed to an anomaly in the function of the liver. In particular, the symptoms could be detected in sucklings on earlier dates of the continuous bathing than in adults, and were apparently more prevalent in the cases with lowered nutrition. 5) The change of the serum Ch-E values following hot-spring bathing seems to be induced by the general and non-specific stimulative exerted by the hot-spring bathing.
