Studies on Bathing with Sodium Sulfate and Sodium Chloride / 日本温泉気候物理医学会雑誌

ABSTRACT

We investigated the effects of bathing with bath preparation (sodium sulfate, sodium chloride, 30g/200<i>l</i>) on the thermal preservability in healthy volunteers. We also investigated these effects on the antioxidative defense system in patients with vibration syndrome (VS). In these investigations, we measured the activities of erythrocyte superoxide dismutase (SOD).<br>After immersion at 41°C for 5min, forearm skin temperature, photoplethysmograph, and transepidermal water loss increased significantly as compared with those after bathing in a plain water.<br>After bathing for 4 weeks at around 40°C for 10min, activities of erythrocyte SOD increased significantly.<br>These data indicate that bathing with the bath preparation has a stronger effect on thermal preservability in healthy volunteers and activation of the antioxidative defense system in patients with vibration syndrome due to a significant increase in activities of erythrocyte SOD.
