Measurement was made on the riboflavin content and the percentage of 3 forms of riboflavin in the organs of rats which were suffered from glycosuria by administration of p-aminosalicylic acid and oxine injection. In the p-aminosalicylic acid administered rats, riboflavin content decreased in the kidney considerably, in the liver and heart slightly, and was unchanged in the pancreas and muscle. In the oxine diabetic rats, riboflavin content decreased remarkably in the liver, kidney and heart, but it did not decrease in the pancreas and muscle. No considerable change was observed in the percentage of 3 forms of riboflavin in the organs of the rats.

An experimental study was made on the changes of physiological functions and the dynamic aspects of thiamine metabolism caused by mental work under hot atmospheric stimulation for a relatively long time. The experimental subjects were 3 healthy men of 20-24 years old. Daily fluctuations in the total thiamine content of blood were observed even under normal conditions, and the content seemed to depend on the amount of the thiamine intake. After oral administration of thiamine, an increase of the level of free thiamine of the blood plasma occurred. This was soon followed by a rise of the level of esterified thiamine of the whole blood. Eventually, both gradually decreased and reached their original levels. Under hot atmospheric conditions for a relatively short time, the level of thiamine of blood was lowered, and free thiamine was not observed in the blood plasma. When a heat stress over the critical temperature (temperature at which a sudden rise of pulse over 100 is observed) was applied to a subject who had been subjected for 2-3 hours to a preliminary stress nearly at this temperature, a marked rise of the total thiamine level of blood was observed in at least 7-8 hours after the preliminary stress. Since no free thiamine was found in blood at this period, it seemed that the rise of the total thiamine level was due to the increase of the esterified form in the plasma. The free thiamine content of the urine increased during this period. When the stress was removed a marked increase was observed. Although seasonal variation seemed to play a role, the exact reason for this phenomenon has not yet been clarified. It was also found that the second heat stress exerted an inhibitory effect on the increase of free thiamine level.

Three groups of rats were fed respectively on low-phosphorus diet (McCollum No.3143 rachitic diet, Steenbock No.2965 rechitic diet, and its modified form), high-phosphorus diet (Steenbock No.2965 rachitic diet containing Na_2HPO_4 instead of CaCO_3), and a control diet. Then, radioisotopic experiments were carried out on the metabolisms of phosphorus and calcium in teeth and surrounding tissues, and effects of vitamin D_2 administration on their metabolisms. Metabolisms of calcium and phosphorus in the dental hard tissues resembled each other in exchange and accumulation on the tissues as same as in the bone tissues. However, some essential differences in behaviors of these elements were observed. Furthermore, the ratio of calcium to phosphorus of the diet, parts of the teeth and the lapse of time were found to cause the difference between calcium and phosphorus metabolisms. Effect of vitamin D_2 administration on the dental hard tissue was greater in the high-phosphorus diet group than the low phosphorus diet one. This effect was not proportional to the amount of administered vitamin D_2 or frequency of administration. A prolonged administration of vitamin D_2 sometimes brought about a decline of metabolism of inorganic matters.

Present report includes the studies on the tryptophan metabolism in the experimentally induced riboflavin deficient rats, administered with pyridoxal phosphate, pyridoxine and TPNH with simultaneous subcutaneous injection of FMN, investigating the urinary excretion of anthranilic acid, kynurenine, xanthurenic acid and N-methylnicotinamide after an oral administration of 50mg of _L-tryptophan. A considerable amount of anthranilic acid, xanthurenic acid and a small amount of N-methylnicotinamide was excreted in riboflavin deficient rats more than those of healthy control group, while kynurenine was almost unchanged. By the administration of FMN alone, the considerable decrease of the excretion of anthranilic acid and xanthurenic acid, and increase of the excretion of N-methylnicotinamide was observed, while kynurenine was unchanged. When pyridoxal phosphate or pyridoxine was given with FMN, xanthurenic acid excretion further decreased and N-methylnicotinamide increased more than in the simple administration of FMN, while anthranilic acid and kynurenine were unchanged. As for TPNH induction, no considerable difference was found except a slight decrease of kynurenine. Furthermore, the excretion of xanthurenic acid decreased in cases of the simple application of pyridoxal-phosphate and pyridoxine. In the control group, no appreciable difference was perceived.

In rabbits it was observed that thioctic acid restored the functions of bromsulfalein and thiobarbiturate detoxication which were lowered due to CCl_4 poisoning. In rats thioctic acid depressed to some degree the accumulation of fat in the chronic CCl_4 poisoning liver. The concentrations of pyruvic acid in blood of rabbits and rats with acute CCl_4 poisoning were significantly higher than normal animals. The administration of thioctic acid caused the depression in the elevation of pyruvic acid levels in both animals. The relative results were obtained for pyruvic acid level in rat liver. For α-ketoglutaric acid levels in blood and liver of rats no detectable difference was observed between CCl_4 poisoning and normal control. Although in rabbits α-ketoglutaric acid concentration in blood was elevated transitorily due to CCl_4 poisoning, thioctic acid did not influence the peak of this acid level.

Pyruvate oxidation was low in liver slices of the rat with experimental CCl_4 poisoning. This activity was restored, significantly by in vivo treatment with thioctic acid. Similar results were obtained with mitochondria of liver cells. In vitro experiments, thioctic acid increased significantly the diminished pyruvate oxidation of liver slices of poisoned rats as was the case with cocarboxylase or coenzyme A, while the increase was very slight in normal liver slices. In both acute and chronic CCl_4 poisoning rats the thioctic acid contents of liver mitochondria were lower compared with those in normal animals.

Experiments on the phosphorylation were made with homogenate, mitochondria suspension fluid and supernatant fluid, all added with riboflavin, of various organs and the blood, using normal rabbits, normal and riboflavin-deficient mice. Phosphorylation of riboflavin was observed in livers, kidneys and small intestines of rabbits and mice and in the chicken blood. It took place in the mitochondria. Although, in small intestines, FMN alone was synthesized from riboflavin, the synthesis of FAD from riboflavin could be found in liver and kidneys. In small intestines glucose-1-phosphate, besides ATP, acted as a phosphate-donor.

Using normal rabbits, solutions of FMN and FAD and percolations of kidney and liver were added each to the blood and to the homogenate of kidneys, liver and small intestines. Riboflavin was measured after the incubation for 30 minutes at 37℃. On the other hand, blood was hourly taken from perpheral veins, renal arteries and renal veins of normal dogs sujected to intravenous injection of 5mg of riboflavin, FMN and FAD each and the riboflavin value in the blood was measured. In kidneys and blood the dephosphorylation of ribflavin was observed, but not in liver and small intestines. The kidney seems to play a very important role in the dephosphorylation of riboflavin.

The authors have previously demonstrated the fact that a large amount of (+)-S-methyl-L-cysteine sulfoxide is distributed in the whole Allium and Colza plants. In the present experiment the authors succeeded in isolating this compound from raddish, cabbage, cauliflower, turnip and Chinese cabbage among the Cruciferae and from scallion in the Allium. This substance had a melting point of 173-174℃, could be converted into NH_3,pyruvic acid and methyl allicin by alliinase and is converted to thiamine methyldisulfide by the addition of thiamine. This extract was regarded as the same compound as that reported by Synge et al. The authors designated it as "methiin".

For measuring the activity of mouse liver rhodanese, the following procedures were found to be most appropriate. After homogenizing the mouse liver, the supernatant layer was employed as the enzyme solution. This solution (1.0 cc) was added with 2.0 cc of 1% NaCN, 0.1 NNa_2S_2O_3,20.0 cc of PH 8.2 phosphate buffer and 30.0 cc of distilled water. It was kept at 38℃ for 2 hours, and deproteinized by trichloracetic acid. After such procedures, the orange color that was brought about by the ferri-reagent was measured by photometer.

The acetone-powdered enzyme of Bacillus subtilis, prepared by the author, was found to decompose alliin or methiin, and produce thiamine allyldisulfide or thiamine methyldisulfide. The enzymatic activity was depressed or counteracted by addition of metaphosphoric acid and potassium cyanide, respectively, or merely by heating procedure. The optimum pH of the activity was about 7.0 and the optimum temperature was 37℃.

The amount of riboflavin excreted in three hour urine at rest in diabetic patients was much more than that of normal subjects, and it tended to decrease with the fall of blood sugar level by medical treatment. The urinary excretion of riboflavin increased by the administration of glucose, ATP or glucose with ATP both in normal and diabetic subjects. By the intravenous injection of insuline, it was observed a fall of riboflavin level in blood, an increase of urinary excretion of riboflavin and a rise of riboflavin concentration of urine.

Thiamine synthesis from pyrimidine- and thiazole moieties by washed cells of several strains of Enterobacteriaceae was studied. In the case of Escherichia coli ATCC 9637,a good yield of thiamine was obtained when the reaction was carried out under an aerated condition in the presence of glucose. The synthesized vitamin was almost exclusively in esterified form and was practically restricted intracellularly. Among 3 strains of thiamine requireing mutants derived from E.coli ATCC 9637,only 70-23,which required intact thiamine, failed to synthesize an appreciable amounts. Strains 70-17 and 26-43,each of which was capable of growing in the presence of pyrimidine- or thiazole moiety respectively, synthesized much more amount of thiamine than their parent strain. All but one (a strain of Shigella dysenteriae 1) of strains examined which belong to Shigella or Alkalescens・Dispar groups were also found to synthesize thiamine from pyrimidine- and thiazole moieties. The yield of the vitamin was greatly improved by the aeration of the reaction mixture.
