Abstract:
It is well known that gynecological complaints are ameliorated by hot spring bathing. We therefore investigated the changes in urinary mucin excretion before and after 14 days of daily hot spring bathing in order to clarify the relationship between hot spring bathing and complaint amelioration. Urine was collected from 28 female adults (64.3±7.0 years old) before and after the 14 days of hot spring bathing. Urinary mucins containing sialoglycopeptides and sulfated glycopeptides were separated from the urine using the ethanol and cetylpyridinium chloride precipitation methods, then indentified with two-dimensional electrophoresis on cellulose acetate membranes.
After the removal of glycosaminoglycan contamination by glycosaminoglycan-degrading enzymes, mucin amounts were determined by the phenol-sulfuric acid method. The results showed that the levels of both sialoglycopeptides and sulfated glycopeptides increased after 2 weeks of bathing. The level of urinary mucin, which is synthesized and excreted from the epithelial cells, increased as a result of hot-spring bathing. Therefore, it is highly likely that the amelioration of gynecological complaints of females is related to the chages in urinary mucin excretion brought about by hot spring bathing.
