It has been well recognized that no known method can produce as strong or as effective a bath as can be given with natural waters. The method of bubbling gas through the bath water is thought to be almost entirely ineffective; the solubility of CO2-gas in water at 40°C is about 10%, but is much further enhanced about 50% by bubbling through an airstone, making fine bubbles. Tablet form of the CO2-bath preparation, made from bicarbonate and succinic acid, produces fine CO2 bubbles so that about 80% of water solubility at 40°C can be obtained. A CO2-bath preparation, 50g tablet, can produce 100ppm in maximum concentration in a bath of 150 liter at 40°C, maintaining the level of more than 60ppm for 2 hours. In order for the safety to estimate the escaped CO2, a large quantity of the CO2-bath preparation, 20 and 50 tablets, was used in a relatively air tight room; CO2 concentration reached the maximum level of 1.9 and 6.6% respectively with a tendency of rapid falling, so that the critical complications could rarely be happened.
Twelve normal female adults were studied using a new model of infrared thermography on the thermographic patterns, the average and the maximum skin temperature of the selected areas, the change of the skin temperature in menstrual cycle and the change of the skin temperature after immersion of the right hand in ice water. The new thermoviewer (JTG-500M) has a computer and can calculate the average and maximum temperature in any rectangular area we draw. It made us possible to detect slight change of the skin temperature precisely. The results were as follows: 1) The average temperature of the trunk was higher than those of the lower extremities and the dorsal surface of the hand. 2) Among the maximum temperatures of the selected areas, the highest was of the trunk, the second was of the dorsal surface of the hand and the last was of the lower extremities. 3) Of the change in menstrual cycle, a significant positive correlation between the basal body temperature and the skin temperature was found. The skin temperature in the progestational phase was significantly higher, by 0.5°C to 0.7°C, than that in the estrogenic phase. 4) The change of the skin temperature after immertion of the right hand in ice water for one minute was surveied at the chest, the abdomen, the back, the dorsal surface of the left hand and the left lower extremity during five minutes. While the skin temperature at the chest and the back dropped, the dorsal surface of the left hand got higher clearly. No change was found at the abdomen and the lower extremity.
Twenty-nine patients with bronchial asthma received spa therapy at Okayama University Medical School, Misasa Branch Hospital. Twenty out of 29 cases were steroid-dependent intractable asthma. Spa therapy was markedly effective in 8 cases (27.6%), moderately effective in 14 cases (48.3%), slightly effective in 5 cases (17.2%) and not effective in 2 cases out of 29 cases. Spa therapy was more effective in the cases with age over 40 years than in the cases under 40 years. Non-atopic type asthma was more successfully treated with spa therapy compared to atopic type asthma. Regarding pathophysiological classification, spa therapy was greatly effective in the cases with bronchiolar obstruction and with hypersecretion.
