Investigation with Bromsulphalein test and determination of urobilinogen in the urine was carried out in men, who are living in Spa Kusatsu in good condition, and take thermal bath once or twice everyday.
Bromsulphalein excretion was enhanced by the stay in the Spa within 4 months and the amount of urobilinogen increased after 5 months, but there was no significant correlation between them.
