ジャーナル フリーUsing the benzoyl peroxide-NaOH method, thiothiamine can be estimated nearly to 100% recovery in its mixture with thiamine. If thiamine is determined by the ferricyanide method in the presence of thiothiamine, the thiamine value obtained, is somewhat higher than the expected one, because thiothiamine is partly converted into thiamine in its dilute solution. Pure recrystallized thiothiamine in its freshly dissolved solution, does not yield thiochrome by the ferricyanide method and even 1 mg thiothiamine in nitrogen-saturated water yields less than 0.2% of the theoretical value. Thus thiamine is successfully estimated by the ferricyanide method if the autooxidation of thiothiamine in the mixture is avoided. Thiothiamine-analogous compounds ; α-aceto-γ-acetoxypropyl-(2-methyl-4-aminopyrimidyl-5)-methyl-dithiocarbamate (I), dihydrothiamine [3-(2'-methyl-4'-aminopyrimidyl-5')-methyl-5-β-hydroxyethyl-2,3 thiazoline] and oxo-thiamine [3-(2'-methyl-4'-aminopyrimidyl-5')-methyl-4-methyl-5-β-hydroxyethyl-thiazolone-2] are proved not to be transformed into thiochrome by the benzoyl peroxide-NaOH method. (I) is warmed with dilute hydrochloric acid and then it proves to be positive by this method ; thus thio-thiamine formation from (I) is shown. We can say the value estimated by the benzoyl peroxide-NaOH method is very reliable and characteristic for thiothiamine.抄録全体を表示PDF形式でダウンロード (544K) -

ジャーナル フリーW. Yonezawa and F. Aoki clarified that a thiaminase-carrying yeast like fungus isolated from the oral cavity belonged to genus Trichosporon. Further, M. Ota reported a specific thiamine requirement of this fungus. The author compared this fungus with some other strains of Trichosporon cutaneum, and found that the Y・A strain can be discriminated from Trichosporon cutaneum from the morphological, physiological, as well as nutritional points of view and also in the production of thiaminase II. The author concluded that the fungus is a new species, closely related to, but different in some respects, from Trichosporon cutaneum.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It was observed that the crude thiaminase II of Bacillus aneurinolyticus could not accelerate the decomposition of cocarboxylase, whereas the crude thiaminase I of B. thiaminolyticus and shell-fish could accelerate it directly. Although pyrimidine compound and thiazole phosphate were detected on a paper strip of paper partition chromatography as decomposition products of cocarboxylase by the crude thiaminase I of B. thiaminolyticus, it was recognized that pyrimidine compound and free thiazole were the end products in the case of crude thiaminase I of shell-fish. However, it was found that thiaminase I of shell-fish also destroyed cocarboxylase directly into pyrimidine compound and thiazole phosphate when NaF or Na_2MoO_4 was used as a phosphatase inhibitor in the reaction mixture of cocarboxylase and the crude thiaminase solution.抄録全体を表示PDF形式でダウンロード (528K) -

ジャーナル フリーFor histochemical observation of vitamin D the authors contrived a new method using fluorescence microscopy. The procedures of the method were described. By this method vitamin D was found as yellow granules in the cytoplasm of the cells. Its distribution in the digestive canal, liver, lungs, spleen, adrenal glands, kidneys etc. were studied, and the authors concluded that the vitamin is mainly absorbed from the jejunum and ileum, stored in the liver adipose tissues, adrenal glands, lungs, spleen, bones, etc. and excreted chiefly from the small intestine and kidneys.抄録全体を表示PDF形式でダウンロード (1169K) -

ジャーナル フリーAlbino rabbits were used and Thyradin, Pretiron and Methiocil were administrated subcutaneously or intravenously. After various intervals, thiamine contents of the retina, choroid, optic nerve, vitreous body, aqueous humor, cerebrospinal fluid and blood were estimated by the thiochrome method. The animals were then thyroidectomized and after a lapse of 1,2 and 4 weeks the thiamine content of the ocular tissues and cerebrospinal fluid was estimated. The main results were as follows : 1) The administration of Thyradin (2 ml per kg) caused an increase of total thiamine content, especially combined thiamine, in the ocular tissues and cerebrospinal fluid. The authors consider that the imigration of thiamine was increased by Thyradin, while phosphoration was specially accelerated. 2) The continuous administraion of Thyradin (0.1 ml per kg) caused a marked decrease of thiamine content. This diminution may be due to an excess of metabolism in ocular tissues aroused by the administration of thyroid hormone. 3) The continuous administration of Methiocil (100 mg per kg) resulted in a marked increase of thiamine content in the ocular tissues and cerebrospinal fluid. Two weeks after the thyroidectomy, the thiamine content increased markedly too. The authors consider that the increase of thiamine content is due to the reduction of metabolism caused by the administration of Methiocil or thyroidectomy. 4) The administration of Pretiron (300 units per kg) and thiamine caused a more remarkable increase of total thiamine content, especially combined one, in the ocular tissues and cerebrospinal fluid than the administration of thiamine alone. This increase in the combined thiamine seems to be due to an acceleration of phosphoration caused by thyrotropic hormone.抄録全体を表示PDF形式でダウンロード (617K) -

ジャーナル フリーThere are two different views on the absorption of thiamine from intestinal tract. One of them is a physical absorption theory based on diffusion, etc. and another a phosphorylation theory. The investigation on the effect of bile on thiamine indicated that there was a significant difference in the disappearance of thiochrome reaction of the vitamin added to bile between normal bile and that of hepatic disease. Bile seems to be participated in the absorption of thiamine from intestinal tract, since the rate of decreasing thiochrome reaction with normal bile was higher than that of hepatic disease. Comparative estimation of total and free thiamine of portal blood, liver, and peripheral blood was made after injection into duodenum of the vitamin with normal bile and with that of hepatic disense. The result indicated that in case of bile of hepatic disease free thiamine increased in portal blood, but remained constant in peripheral blood, while in case of normal bile combined form of the vitamin in portal blood. These findings suggest that thiamine might be absorbed as a phosphorylated form. Furthermore, experiment on the urinary excretion of the vitamin and the content in the liver showed that the absorption of the vitamin was inferior in dogs with hepatic disease. When thiamine was orally administered to patientts with protal hypertension, the vitamin in peripheral blood did not so much increase, while when the vitamin was parenterally given and liver protecting treatment was performed, total and combined form of the vitamin did not so much increase in patients with severe hepatic disease, but the combined form of the vitamin increased to some extent in patients with light hepatic disease. Pareuteral administration of thiamine and simultaneous liver protecting treatment seem to be necessary for patients with hepatic disease.抄録全体を表示PDF形式でダウンロード (1568K) -

ジャーナル フリーWhite male rabbits were divided into 2 groups, and injected with thiamine or thiaminepropyldisulfide, 2 mg per kilogram respectively. Then the thiamine contents in the blood and the neural tissues were measured following the course of time. Immediately after the intravenous injection, thiamine contents in the blood showed the maximum value and it diminished with the lapse of time thereafter. Generally, the rate of increase of thiamine contents in the neural tissues after the administration was slower than that in the blood. Thiaminepropyldisulfide had a stronger power of increasing thiamine contents in the blood and the neural tissues than thiamine, and the maintenance of high concentration was apparently more pronounced also.抄録全体を表示PDF形式でダウンロード (664K) -

ジャーナル フリーWhite male rabbits were divided into 2 groups, and injected with thiamine or thiaminepropyldisulfide 2 mg per kilogram daily, for several days. The animals were killed at 36〜40 hours after the last injection and the thiamine contents in the blood and the neural tissues were measured. The concentration of thiamine in the blood did not increase even after 60 days of consecutive administration. Thiamine in the neural tissues was increased with successive administration and its tendency was more pronounced in the thiaminepropyldisulfide group than the thiamine group.抄録全体を表示PDF形式でダウンロード (563K) -
