ジャーナル フリーFor the purpose of studying the toxicity of borate on the blood, the effects on erythrocytes of guinea pigs were investigated. From the results obtained, the boron levels in erythrocytes were elevated by addition of borate to blood, and it was found that boron can enter into erythrocyte at the considerable rate according to the amount of borate added. The enzyme system of anaerobic glycolysis in erythrocyte was found to be markedly inhibited by addition of borate. It was also found that the levels of methemoglobin in erythrocyte revealed a remarkable tendency to increase after boron was added to erythrocyte. Similar results were also obtained in vivo experiments.抄録全体を表示PDF形式でダウンロード (533K) -

ジャーナル フリーZinc and tin, constituent of can, are dissolved into canned food owing to the potential difference caused by contact of different kinds of metals. The amount of dissolved metalic ion was affected by water quality and the kind of metal. The amount of dissolved tin into water of canned food from can was almost proportional to the concentration of nitrate ion in water but the amount of zinc was markedly increased at less than 5 ppm of nitrate ion.抄録全体を表示PDF形式でダウンロード (447K) -

ジャーナル フリーSorbic acid (SOA) in food was separated by steam distillation of aqueous solution of the sample saturated with sodium chloride and adjusted to pH 3.3-3.5 with citric acid. Nearly quantitative amouont of SOA (0.5-2 mg) was recovered in 100 ml of distillate. The distillate was diluted five times with phosphate buffer (pH 5.2) and absorbance of the diluted solution was measured at 256 mμ. The other food preservatives were distilled together with SOA, but did not interfere the determination, if these were within the authorized maximum limit. Nitrofurazone, nitrofurylacrylamide, artificial sweeteners, coloring materials and other materials in food were not ditilled.抄録全体を表示PDF形式でダウンロード (517K) -

ジャーナル フリーA simple and rapid method to test water soluble coal-tar food colours legally permitted in Japan was studied using alumina column chromatography and paper electrophoresis and the following results were obtained. (1) As the buffer solution for the paper electrophoresis 5N acetic acid was most advantageous, because of inconsiderable tailing and minimized variation of relative mobilities to flavianic acid. (2) In order to identify the dyes which were difficult to identify under above mentioned condition or to increase the certainty of the identification of the other dyes, 1% borax solution was used in place of 5N acetic acid as buffer solution to give good results. (3) Mobilities of dyes in paper electrophoresis were effected with ambient temperature, but the relative mobilities to flavianic acid did not vary. (4) The application of this method to the dyes contained in powdered juices on the market gave satisfactory results, and this method could be applied to test the sample in which five colours were mixed. (5) Isolation of the dyes from the powdered juice was carried out by the alumina column chromatographic method under the mild condition, so this will be applicable to the unstable substances.抄録全体を表示PDF形式でダウンロード (645K) -

ジャーナル フリーThe disinfection method of fresh cabbages was investigated for providing with wholesome foods. 1. Chopped cabbage which was served at restaurants was polluted with Coli Group. 2. Even the 11th to 13th inner leaf of cabbages was contaminated bacteriologically. It was considered that cabbage itself had been already polluted before chopping. 3. Dipping in 20 to 30 ppm of NaClO Solution was fairly effective on disinfection of cabbage. 4. Vitamin C in cabbage was not affected by this treatment.抄録全体を表示PDF形式でダウンロード (754K) -

ジャーナル フリーThe amount of zinc in eye of ten kinds of fishes was determined quantitatively by the Dithizone method. Zinc content was generally proportional to the size of eye, and the contents in a fresh eye were 0.02 to 0.08%. The eye was sectioned into lens, vitreous body, iris, retina and choroid, and the zinc contents in each sections were determined ; the largest amount of zinc was contained in the choroid, and decreased in order of the retina, iris, lens and vitreous body. About 80% of zinc in the eye was present in the choroid, and about 18% in the retina.抄録全体を表示PDF形式でダウンロード (531K) -

ジャーナル フリーGas chromatographic analyses of drugs and food additives have been reported by many authors. Experimental conditions, especially the selection of stationary phase, however, have been selected only empirically, and the theoretical considerations on these selections seem useless to be applied in practice. Considering the purpose of this instrument, it is preferable to use a few kind of staitionary phases. In order to know the effectiveness of a stationary phase, high vacuum silicone grease, for the separation of drugs, gas chromatographic analysis of 20 drugs were carried out with the same experimental condition. Acetanilide, ethyl aminobenzoate, phenacetin, caffeine, aminopyrine, antipyrine, barbital, chlorpheniramine maleate, santonin, testosterone, and diethylstilbestrol were separated satisfactorily, whereas quinine hydrochloride and quinine sulfate were not detected. Variation in results was observed with different lot of the stationary phase, but the good results were obtained with a suitably aged column. Introduction of 200∼300 mg of the sample were proved to be appropriate. Consequently, in order to obtain good and reproducible results, stationary phase must be selected with respect to its kind as well as to its aged state otherwise reproducibility in results could not be expected.抄録全体を表示PDF形式でダウンロード (878K) -

ジャーナル フリーArsenic over permissible quantity was detected in water supplied from water-works of a primary school at Esashi, Iwate. The content of arsenic in surrounding soil water source was higher than that of other places. It was considered that the school water has been contaminated with arsenic dissolved out of surrounding soil, since gushed and oozed water was utilized as the water source. The contents of arsenic in urine, hair and nail of pupils in the school were determined. Urine : 46 pupils of 6th year (primary school) 0.048±0.023 mg/L (As) 43 pupils of 3rd year (junior high school) 0.054±0.019 mg/L (As) Hair : 140 pupils of the primary and junior high scool 0.31±0.12 μg/g (As) Nail : 136 pupils of the primary and junior high school 0.95±0.24 μg/g (As) These values were almost same as normal arsenic content.抄録全体を表示PDF形式でダウンロード (717K) -

ジャーナル フリーRodenticidal effect, suitable concentration, repellency and taste of some rodenticides, i.e., G-100 (coumarin-3-carboxylate), Tl2SO4 and Warfarin [3-(α-Acetonyl benzyl)-4-hydroxycoumarin], etc., were examined in houses, store house cafe and so on, where the wild rat lived or stealed in. It was found that G-100 and the mixture [G-22 (6-coumarinylamine-coumarin-3-carboxylate) : G-100=2 : 1] had relatively good rodenticidal effect and that suitable concentration of the drugs to gain the rodenticidal effect within 2 or 3 days were 0.3% with solid type, 3% with paste type and 3% with powder type. Then it was found that simultanious control at whole place was necessary for rodenticidal procedure.抄録全体を表示PDF形式でダウンロード (879K)
