Abstract
1) Subcutaneous injections (ACTH 10mg) were given to the 15 healthy visitors at Kusatsu Hot Springs, and the changes in eosinophil counts in blood were examined. Through this examination we have learned that the more the length of one's stay at Kusatsu Hot Springs is prolonged, the more marked balneo-climatological influence is proved in the decrease of eosinophil counts upon ACTH injection.
2) When the length of their stay at Kusatsus Hot Springs was prolonged more than 2 months, the change of their blood-sugar caused by the injection of ACTH was enhanced, and most of their highest values showed higher level than 150mg/dl.
As for the people whose duration of stay at Kusatsu Hot Springs was less than 2 months, the highest values remained under 150mg/dl.
