A few attempts were made to study the effect of Tamagawa hot spring bathing upon the capillary resistance in healthy subjects and patients with hypertension, rheumatoid arthritis and fibrositis.
The results may be summarized as follows:
1) The capillary resistance decreased more significantly in patients with hypertension and rheumatoid arthritis than in healthy persons, but there was no difference in capillary resistance between healthy persons and patients with fibrositis.
2) Similarly, single bathing showed a decrease in capillary resistance both in healthy subjects and patients immediately after bathing, but tended to return gradually to the pre-bathing value about 1 hour later.
3) Successive bathing clearly increased capillary resistance in patients with hypertension in whom the decrease of capillary resistance was apparent. Such tend was also observed in patients with rheumatoid arthritis. The variation in capillary resistance in them brought forth by single bathing gradually grew smaller in degree with progress of successive bathing and showed a tendency to be similar to that in healthy subjects.
No significant variation was observed in capillary resistance in healthy persons and patients with fibrositis.
4) It can be said from the results mentioned above that balneotherapy is very effective for the treatment of rheumatoid arthritis and hypertension.

This paper deals with general survey of hot spring curative treatment at Higashine Spa, Yamagata Prefecture, and the effect of this spa on the capillary resistance and the variation in the blood pressure.
The results of the medical survey are summarized as follows:
1) Higashine Spa consists of saline weak common salt springs, in each of which chemical components are almost the same.
2) The visitors to this spa are inhabitants of Yamagata Prefecture, farmers being the largest in number.
3) Most of them (78%) are old men and women over 50 years of age, and the number of women are four times that of men.
4) The examination of spa visitors reveals that hypertension stands at the top. However, in most cases, the chief complaints are of rheumatic disorders in natwe and hypertension is found at the time of medical examination.
5) Those who bathe five times a day are the largest in number.
6) Those who noticed the bathing reaction are small in number. The bathing reaction may be considered as a serious thermal crisis.
7) Bathing in this hot spring increases the capillary resistance and lowers the blood pressure.
Accordingly, bathing in this spa, under a proper guidance, may be effective in the treatment of hypertension. For balneal treatment of hypertension, physicians' directions as to how and when patiens should bathe, will be necessary: unplanned bathing cannot be approved of.

The results of our general and medical survey are summarized as follows:
(A) About Shinjo Spa
1) Most of visitors to this spa are residents of Yamagata Prefecture and engaged in agriculture.
2) In age they are 20 to 50.
3) Visitors who are few in number came to this spa for the purpose of spa treatment. Most of them visit this spa for recreation.
4) Most visitors take bath 2 to 3 times a day.
5) The bathing reaction and its effect are obscure, because most visitors do not stay here long enough for observation of the effect. It is, however, verified that this spa is effective in keeping the body father warm for a long time.
(B) About Niiyama Spa
1) Most visitors are residents of Yamagata Prefecture and those from neighboring prefecture are small in number. Half of visitors are farmers.
2) Most visitors are old in age, male and female visitors are almost equal in number.
3) The larger number of visitors come here for balneotherapy of or rehabilitation from diseases, especially neuralgia, rheumatism.
4) Most visitors are conscious of the good effect of bathing, but those who are conscious of thermal crisis are relatively few in number, being 9.8% of the total number of visitors.
The authors are indebted to the Pharmaceutical Section, Sanitation Bureau, Yamagata Prefectural Office and the Sanitation Section, Shinjo City Office for assistance given to the present survey, and to Shinjo and Niiyama Spa Associations for careful cooperation.

The results of our general and medical surveys are summarized as follows:
1) The visitors to this spa are inhabitants of Yamagata prefecture, farmers being the largest in number.
2) Considering the fact that more than half the number of spa visitors come here with therapeutic or convalescing purpose, this spa may be said to be a spa to which visitors come with the sole object of curative treatment.
3) Visitors came for the treatment of common cold, hypertension, neuralgia and diseases of the stomach and intestines respetively from the frequency of diseases. The fact that the visitors with cold were largest in number was probably because of the prevalence of common cold at the time of our survey.
4) Half the number of spa visitors stayed for about 2 weeks, and most of them took bath four to five times a day for curative treatment.
5) 40.1% spa visitors drank hot spring water for curative treatment. Which incidence is higher than that in our previous reports for other Tohoku Area.
6) Only 6.1% of the visitors came to the spa under doctor's direction. Those who noted the bathing reaction: anorexia, feeling of weakness etc., were 23.1%
7) In the tubeless gastric analysis (Gastrotest) scarcely any change was observable for successive drinking of hot spring water.
8) In most cases the oral temperature measured at the time of bathing in this spa never returned to the value before bathing for two hours and the feeling of warmth remained for a long time. This is probably due to the chemical properties of the spring waters and proper treatment after bathing.
