岡山大學放射能泉研究所 Acta Medica Okayama 3 1950 新しい試藥によるカルシウムの直接比色定量法及び直接滴定法 39 42 EN Takashi Ashizawa 10.18926/40364 The anthor found that azocal-A reacts only with calcium, and devised a direct colorimetric, and a direct titration method for calcium determination using azocal-A as an indicator, and obtained a satisfactory result. Accuracy : detectable amount in NaOH……0.28 γ, of Ca ; detectable amount in NH(4)OH……2 γ, of Ca. Sensibility……1 : 125,000 & 1 : 17,500 respectively. Interfering substances : Fe, U, Ni, Co, Hg, Ag, citrate, tartarate, oxalate, large amount of NH(4) salts, Sr, Mg. Not interfering subst. : Ba, F, acetate and silicate. Reagents : Saturated soln. of azocal-A in weak NaOH soln.. Spot test procedure : Place a drop of the acid or neutral test soln. upon white spot plate, add 1 drop of azocal-A soln., and mix them. If a yellow color appears, calcium is present. Colorimetric method: Transfer water sample containg not more than 0.05 mg of calcium, and not more than 5 mg of Fe, Mn, Mg, etc. to a 20 cc colorimetric tube, add 0.5-1 cc of azocal-A soln. and 0.5 cc of 6N-NaOH soln.. Allow it to stand for 10 minutes. Then compare the resulted yellow color with standard Ca soln. prepared similarly and simultaneously. Volumetric method : Amount determinable : 0.1 g of calcium. Transfer 40 cc of sample containg 5-100 mg to a 100 cc Erlenmeyer's flask, add 0.5 cc of 6N-HCl, add azocal-A to the amount of pink color as caused by methyl orange in acid soln.. Make alkaline with 1 cc of 6N-NaOH. Add 10 cc alcohol to every 40 cc of the sample solution. Then its color turns to yellow. Titrate with 0.1 N oxalate soln.. 1.0 cc of 0.1 N oxalate soln. is equivalent to 2.0 mg of Ca. Absorption band of the acid soln. at 4900 A, alkaline soln. at 5000 A, Ca-compound at 4300 A. The azocal-A is o-carboxy-benzol-azo-2-naphtol 3, 6-disulfonic acid prepared from anthranilic acid and R-salt. No potential conflict of interest relevant to this article was reported.

Sotozono proved that the reduced ascorbic acid content in the blood increases after the Radonspring bath. Before and after thermal bath the author measured the time necessary for the complete decoloration of intradermally injected dichlorphenol-indophenol solution. Compared with the plain water bath at a same temperature, the Thoron spring bath seems to have a tendency to reduce the time necessary for the decoloration.

岡山大學放射能泉研究所 Acta Medica Okayama 4 1951 溫泉水と人體皮膚膜電位差 49 53 EN Yoshio Oshima 10.18926/15525 The membrane potential difference with the living human skin between the physiological saline and the mineral waters was measured. The hypotonic mineral waters, that have a pH higher than the isoelectric point of human epidermis, showed a positive potential against the physiological saline. The membrane potential difference of these mineral waters against the physiological saline at the same temperature tends to increase by raising the water temperature. The acid waters showed either a positive or a negative potential against the physiological saline. The membrane potential difference between the mineral wates at room temperature and at the temperature raised above it is increased according to their temperature difference, No potential conflict of interest relevant to this article was reported.

岡山大學放射能泉研究所 Acta Medica Okayama 4 1951 放射能泉に関する研究(XXVIII) 放射能泉入浴の循環器に及ぼす影響 (第1報) 23 39 EN Susumu Onoda 10.18926/15523 The author investigated the changes in skin temperature, oral temperature, blood pressure, pulse rate, respiration rate and weight of body before and after a radio-active thermal bath in Misaswa, and compared the results with the corresponding changes after a plain water bath at a same temperature (43℃) with same duration (5min.). A rise in skin temperature after the thermal bath durated longer than after the control plain water bath. Changes in oral temperature did not correspond to the changes in skin temperature and to the suhjective warm feeling. Changes in the pulse pressure showed no significant difference between the radio-active thermal bath and plain water hath. But a more prolonged lowering of the minimal blood pressure was proved after a radio-active thermal bath than after a plain water bath at same temperature with same duration. The response in blood pressure to thermal bath was more marked in winter than in summer. A rise in pulse rate was recognized after all kinds of hot baths, but no difference was proved between them. A slight acceleration of respiration rate and a loss in weight were observed after hot bath at 43℃ for 5 minutes. But these effects were slighter after radio-active thermal bath than after plain water bath at same temperature and same duration.
