Using BASUKURIN, an inorganic salts, its power of relieving bathers of their subjective symptom was analysized by main component analysis.
Subjects were 30 patients per each of 6 groups of disease, i. e. neuralgia, rheumatism lumbago, stiff shoulder, contusion and distorsion, with only cases of more than 2 week-suffering for the latter of 2 diseases Bathing test was performed in 400L of elevator bath added with 34g of BASUKURIN compsed mainly of sodium bicarbonate and sodium sulphate and with 23g of placebo composed mainly of granuated sugar, respectively. Both bath drugs, supplied by Tsumuar Juntendo Inc., were jasmin-odored. In some caces, 50 L-partial bath was also used. According to the double blind method, those subjects were bathed successively in BASUKURIN-bath and pracebo-one for 3 consecutive days, and asked for their answers to the enquete about the difference which they possibly felt there between. The choice of which bath was arbitrary. Bathing was taken at 40°C for 10min. The enquete comprised 17 items to which subjectively expressed answers were corresponded, which answers being evaluated 7 stepwise.
(1) For the neuralgia group, effects were observed as “physiologically improved” and/or “getting warmed”. Improvement were made mainly in pain perception disorder and joint dysfunction.
(2) For the rheumatism group, effects were observed generally as “getting warmed”, and as “feeling familiar” and/or “feeling refreshed” for the case of skin hypersensitiveness.
(3) For the lumbago group, effects were observed also as “getting warmed” frequently, and as “feeling similar like hot spring” and/or “feeling familiar” for the relief of muscle hypertonus.
(4) For the stiff shoulder group, effects were observed not only as “getting warmed” generally, but also on the dysfunction of cervico-shoulder-arm and as “feeling familiar” for the relief of muscle hypertonus,
(5) For the contusion group, effects were observed as “feeling refreshed”, “feeling kept warmed”, “feeling familiar”, “feeling affined”, etc. accompanying with the local pain, malaise, cold sensation and so on.
(6) For the distorsion group, effects were observed characteristically as “feeling familiar” and “improved circulation” accompanying with circulatory insufficiency of the lower extremities.
As mentioned above, from the viewpoint by diseases, main symptoms will be improved directly, and improvements will be expressed as in the disease itself. On the other hand, from the overall viewpoint, score of improvements will be leveled, so that “getting warmed” and “feeling warmth” will be emphasized as common factors. Improvements, however, may be ascribable to the effects of both sodium bicarbonate and sodium sulphate as main ingredients of BASUKURIN.
