Abstract In recent years, coulometric analysis has been developed and widely used as a technique for the determination of substances in solution by measuring the quantity of electricity required for the completion of a reaction in an electrolysis cell. Of two coulometric techniques, i. e., coulometric titration with a constant current and coulometric analysis with a controlled potential of a working electrode, the latter is more interesting to the author, because by this method both electrolytic separation and quantitative determination of chemical species can be achieved simultaneously. Especially, the use of a mercury cathode as the working electrode(1)) has an advantage that the optimum control potentials can easily be determinable from polarographic data. In our laboratory, we took up the coulometry of uranium as one of the interesting themes of researches when we had an opPortunity in studying various kinds of analytical methods for uranium in accordance with the request by Japan Atomic Fuel Corporation. The coulometric determination of uranium (VI) by using a mercury cathode at a controlled potential was studied by G. L. Booman, W. B. Holbrook and ]. E. Rein(2)). It was found to be very useful for the analysis of uranium in a highly enriched nuclear element which underwent fission to an appreciable extent. But the instrument used by them(3)) was complicated and expensive. Therefore, a simple counter millicoulometer has been coustructed in our laboratory, a readymade potentiostat (electrical instrument for automatic controlled potential electrolysis) being tried for electrolysis. By these instruments, the author studied the fundam ental conditions of coulometry for uranium and tried the successive determinations of uranium and thallium in mixed solutions.

Title Alternative CHEMICAL STUDY ON SEKIGANE HOT SPRINGS, TOTTORI-KEN
FullText URL pitsr_029_038_049.pdf
Author Sakanoue, Masanobu| Mifune, Masaaki|
Abstract The chemical and physical characteristics of the thermal and ground waters in Sekigane Hot Springs were determined. The content of the following chemical constituents was determined: Cl(-), S0(4)(2-), HCO(3)(-), Ca(2+), As, F, U and Ra. The relationship between water temperature and depth of spring wens was found to be indicative of the presence of a fissure, in agreement with the conclusion reached geologically by Sugiyama. The water temperature, the e1ectricconductivity and the content of chemical constituents of the ground water were as expected markedly lower than those of the thermal water. As a whole, however, the water temperature, the electricconductivity and the content of SO(4)(2-), HCO(3)(-), Ca(2+), As and F are in positive and linear correlation with the Cl- content. In other words, these characteristics of the waters, excluding the U and Ra content, correlate positively and linearly with each other. This was interpreted to mean that a thermal water of high salinity is simply diluted by a cold ground water of very low salinity, and that a ground water of relatively high salinity is contaminated by thermal water. The content of U and Ra of these spring waters is lower than that of the spring waters in Ikeda, Shimane-ken, and Misasa, Tottori-ken, where radioactive springs also issue. Finally, it is concluded that As and F will be as useful as Cl- in chemically locating a new site for a spring well in Sekigane because of the low contamination due to human life of ground water by these elements.

Title Alternative THE FLUORINE CONTENT OF WATERS AT MISASA HOT SPRINGS
FullText URL 029_028_037.pdf
Author Mifune, Masaaki| Ohtsuki, Fumio|
Abstract The fluorine content of certain thermal and ground waters in this district was determined colorimetrically by the use of Neo-Thorin. The temperature and the chloride, bicarbonate and calcium content of the same waters were also determined. It was found that fluorine content ranged from 0.6mg/l to 9.1mg/l in the thermal waters and was less than 0.6mg/l in the ground waters. The positive and linear correlation between the fluorine content and the Cl(-), HC0(3)(-), and Ca(2+) content was considered to be the outstanding characteristic of the thermal waters of this area. From these facts, it is concluded that the fluorine in the waters at Misasa Hot Springs is originally introduced from the same source as the thermal waters.

Title Alternative A Clinical Investigation of the Gastric Acidity of 113 Patients with Cholecystopathy
Author Nakahara, Yasuhiro| Ohtani, Mitsuru|
Abstract In order to investigate the relationship between gastric acidity and various clinical and labolatory test findings in patients with cholecystopathy, the authors studied the case records of 113 such patients treated at this institute. The results obtained were as follows. 1) Concerning gastric acidity, 13,6%, of the 113 patients showed hyperacidity; 11,1%, normal acidity; 33, 0%, hypoacidity; and 42,3%, anacidity. 2) A higher percentage of cases showing low gastric acidity was found among those patients with a longer history of the disease. 3) Cases evencing lower level of gastric acidity tended to be characterized by a higher frequency of abnormal laboratory findings and clinical symptoms.

Abstract The authors gathered 78 cases of gouty arthritis reported in Japan between 1898 and 1960, and analysed them statistically. 1. The incidence of gouty arthritis appears to have increased since about the end of the 2nd World War, especially since 1955. 2. The age of the presumptive onset of the disease is lower in Japanese than in white populations. 3. In many cases, the gouty patients were wrongly diagnosed as rheumatoid arthritis, synovitis or panaritium patients, and only 20 per cent of the cases examined were diagnosed correctly at the first consultation. The author stresses that diagnosis at an early stage is necessary to avoid serious complications such as cardiovascular and renal involvements. If the condition is satisfactorily controlled by diets and drugs, however, the prognosis for gouty patients is excellent.
