臓器反射スペクトル法と内視鏡を併用して胃粘膜血流を測定し，当院温泉水飲用の消化機能に対する基礎的検討を胃粘膜血流を指標に行なった。温泉水の対照として空気と白湯を選び3群に分け検討した。その結果，温泉水は空気に比し胃粘膜血流を増加させる作用を有していることが示唆された。また温泉水は部分的ではあるが白湯にくらべても胃粘膜血流を増加させる作用があることが示唆された。よって飲泉療法の消化器疾患に対する臨床的有用性が胃粘膜血流の面からもうかがわれた。Short-term effects of spa-drink therapy on gastric mucosal blood flow were evaluated by an endoscopic organ reflex spectrophotometry, using Olympus XQ-10. Thirty-four subjects were randomly divided into three groups : 10 subjects for warm spa-water (40±C) infusion group, 10 subjects for warm tap-water infusion group, and 14 subjects for warm air infusion group. Intragastric infusion of water or air was performed through the fiberscopic infusion channel. Gastric mucosal blood flow was determined just before and 10 min after the infusion on the three points of gastric mucosa : lesser curvature of the angle, the antrum and the pylorus. Following results were obtained : 1) Spa-water exerted a beneficial effect on gastric mucosal blood flow as compared to air. The difference was statistically significant on all of the three points. 2) Spa-water tended to exert a beneficial effect on gastric mucosal blood flow as compared to tap-water. The difference, however, was significant only on the mucosa of the gastric antrum. In conclusion, it was suggested that spa-drink therapy was useful for the treatment of chronic gastritis and gastric ulcer in which impairment of gastric mucosal blood flow plays an important pathogenetic role. Studies on the long-term effects of spa-drink therapy on the gastric mucosal blood flow are now in progress
