Ist Report. A Devised Method for Mercury Determination in UrineYutaka Fujimura1963 Volume 17 Issue 6 Pages 239-244
Published: February 10, 1963
Released on J-STAGE: February 17, 2009
JOURNAL FREE ACCESSThe difficulties associated with the determination of trace mercury in urine were discussed, and a simple and accurate method was devised as follows:
1. Urine was completely digested in sulfuric acid with hydrogen peroxide and a little amount of permanganate in order to prevent the contamination of mercury from oxidants such as nitric acid or excess permanganate.
2. Mercury dithizonate was formed under the acidity with sulfuric acid between 3.2N and 4.3N preventing the disturbing effect of copper on the extraction of mercury.
3. Excess of dithizone was extracted off from organic phase with 9N ammonium hydroxide solution according to Natelson.
4. The final yellowish orange color of mercury dithizonate in carbon tetrachloride was measured with the spectrophotometer at 490μm.View full abstractDownload PDF (791K) -
Report 1. Observations of Functions of Interbrain by the Ultra-shortwave Irradiation TestHiroshi Takigawa1963 Volume 17 Issue 6 Pages 245-252

JOURNAL FREE ACCESSFor clarifying the relation between some environmental factors and functional changes of brain, the functions of interbrain were investigated by way of Ultra-shortwave irradiation. Three environmental conditions were set up; light, dark, and noise.
The illumination in the light condition was 3200 Lux with day-light fluorescent lamp. For the noise condition, 100 to 105phon noise characterized by wide octave band spectrum was used. The subjects were healthy 5 men and 3 women, and stood in hunger from the early morning under each condition during the study. They were irradiated by Ultra-shortwave (irradiation factors: wave length, 6m.; secondaty current, 1800mA.) at their temporal regions through the interbrain for 15 minutes.
The results obtained were as follows:
1) The changes of the amount of blood sugar, urinary 17-K. S., and uropepsin by the irradiation were not significant between light and dark condition. But the decrease in the number of eosinophilic leucocytes by irradiation was greater in the light than the dark.
2) The increases in the amount of blood sugar, urinary 17-K. S., and uropepsin, and the decrease in the number of eosinophilic leucocytes by irradiation were not observed after exposure to noise.
These facts give proof of the dysfunctions of interbrain in exposure to noise.View full abstractDownload PDF (1105K) -
Part. 1. Oxygen Uptake and Glycolysis of the Various Parts of Brain under Some Environmental ConditionsYoshio Inden1963 Volume 17 Issue 6 Pages 253-260

JOURNAL FREE ACCESSThe experiments were carried out for clarifying the relation between adenohypophyseal dysfunction and higher center of brain in exposure to noise. For the noise condition, 100 to 105 phon noise characterized by wide octave band spectrum was used, and the temperature in the cold as the general stress was -10±2°C. The rabbits were exposed to noise for 4 hours or to cold for 40 minutes. Thereafter, oxygen uptake, glucose consumption and lactic acid formation were determined in homogenates of telencephalon, diencephalon, mesencephalon, cerebellum, pons and myelencephalon.
As the results, in the noise condition, the disturbance of glycolysis of diencephalon was observed, but not in the cold condition.View full abstractDownload PDF (1091K)
