Title Alternative Studies of the radio-active springs. XXV The effect of Thoron spring bath on Rotter's reaction
FullText URL rbl_003_018_020.pdf
Author Oshima, Yoshio|
Abstract In the preliminary papers the author reported that the Thoron in thermal water passes throngh the skin and stimulates the subcutaneous connective tissue cells. 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.

Title Alternative Direct colorimetric and volumetric determination of calcium with new reagent
FullText URL rbl_003_039_042.pdf
Author Ashizawa, Takashi|
Abstract 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.
