JOURNAL FREE ACCESSPyrroglutamic acid is easily produced from glutamic acid by heating in vitro, and also it seems quite probable that in vivo glutamic acid is transformed into proline, oxyproline, ornithine, or other amino acid via pyrroglutamic acid. This acid is therefore worthy of consideration from the nutritional point of view. It is also known that pyrroglutamic acid is contained in some of our foods and seasonings.
Meanwhile Austerweil and Delort-Stachenko reported that pyrroglutamic acid showed some toxity. But our experiment on rats proved that D- and L-pyrroglutamic acids were harmless even when 1-2mg. were injected to the animal subcutaneously daily for about a month.View full abstractDownload PDF (300K) -
V. Correlation between the Methionine Contents and Amino Acid Nitrogen, Non-Protein Nitrogen in SerumHideo Yokota1958 Volume 10 Issue 5 Pages 222-225

JOURNAL FREE ACCESSPreviously I reported that the methionine contents in serum of the patients of pulmonary tuberculosis were not related to the condition of tuberculosis, but closely to the liver functions and increased when these were disturbed. In this report I discussed the correlations between the methionine contents, amino·acid nitrogen, and non-protein nitrogen in serum.
It was observed that when liver functions were slightly disturbed, the methionine content increased somewhat and a correlation between the methionine content and amno·acid nitrogen was singnificant, though a correlation between the methionine content and non-protein nitrogen was insignificant. Also it was observed that when liver functions were severely disturbed the methionine content increased extraordina-rily, and that especially at an acute, diffused, and severe liver damage, amino·acid nitrogen and non-protein nitrogen increased similarly.View full abstractDownload PDF (794K) -
VI. Influence of Intake of DL-Methionine on the Methionine Contents in SerumHideo Yokota1958 Volume 10 Issue 5 Pages 226-230

JOURNAL FREE ACCESSTwo normal male adults were admistered orally 10 grams of DL-methionine and then the methionine contents in serum and urine measured. The methionine content in serum increased rapidly after 15 minutes, reached the highest level (116.5γ/ml) after 2 hours, and began to decrease 10 hours later gradually.
An excretion-rate of methionine in urine was greatest after 2 hours; about I. II grams of DL-methionine and 0.089 grams of L-methionine were excreted in 24 hours. Over 60% of total excretion of D-methionine in 24 hours excreted in the first 6 houts, whereas the excretion of L-form was less than 40% and seemed to delay as compared with D-form.
When liver functions were slightly disturbed, the serum methionine contents of the end of 24 hours after take incorporation of DL-methionine increased slightly or remained normal. But when liver damages were severe, it remained extremely high. Some clinical singnificance of the administration of methionine for severe liver damages was discussed.View full abstractDownload PDF (1081K) -

JOURNAL FREE ACCESSInvestigations on the relation between riboflavin and carbohydrates in unhulled rice during the ripening period were made using two rice varieties; Futaketori and Aikoku No. 1. In each variety, total riboflavin was aboundantly found in unhulled rice 10 days after heading, and was decreased rapidly around 35 days after heading, then the riboflavin level was constant. Free riboflavin dominated ca. 90% of total amount of riboflavin 10 days after heading, then the free riboflavin gradually decreased in its content in both varieties; Futaketori took 226 days and Aikoku No. 1. needed 223 days after heading to get 40% level. Both varieties showed a rapid increase in total sugar content during the first month after heading, then maintained a constant sugar content. The ratio of reducing sugar to total sugar and that of non-reducing sugar to total sugar were rapidly lowered during the period of 20 days. However, 60 days after heading, the ratios gradually decreased to less than 1%, and no change was noticed further. It seemed to be a negative correlation between starch and free riboflavin, but any particular relation among other component was not found.View full abstractDownload PDF (521K) -

JOURNAL FREE ACCESS1. We exermined on the students of our college what kinds of vitamin-preparates were usually taken as tonic.
It was found that in 1951, average 2.1 persons per family took vitamin-remedies occasionally, and one person per 5.2 families took them daily. In 1957, this increased to the rate of one case per 1.2 family.
Among the various kinds of vitamin-preparates, vitamin B1 was the favorite, a few took vitamin A and few vitamin B2 and C.
2. The effects of the vitamins was observed on the growth rate of male albino rats, which were divided into three groups; the control group, the protein rich group fed simultaneously with the mixture of vitamin B-complex, and the protein rich group fed vitamins after certain interval.
The basal rations of food were the same throughout three B groups. It was found that the protein rich group fed at the same time with vitamins showed more rapid growth than the group fed vitamins seperately.
This fact suggests that the food efficiency is raised when the essential ingredients are taken at the same time.View full abstractDownload PDF (1076K) -

JOURNAL FREE ACCESSThe experiments, using the Fricker photometer, were undertaken to test the effectiveness of Guronsan to prevent fatigue caused by strenuous exercise.
The first experiment was undertaken on ten students belonging the University Riding Club.
Their daily exercises were horse riding and jumping for an hour and a half in the morning and afternoon. When 15 tablets of Guronsan, three times a day were given to each student 5.1% less fatigue were observed than usual.
The second experiment was undertaken on 60 members of the University Judo Club. Half of them were given 15 tablets of Guronsan. All members took an equal part in the exercises, which run for two hours, both in the morning and afternoon. In this case also the fatigue was 7.9% less in the Guronsan group than in the control.View full abstractDownload PDF (520K) -

JOURNAL FREE ACCESSThe rice bran oil extracted with benzene has deep color, and it is difficult to decolorize it. Alkali and Fuller's earth treatments were usually used to decolorize it, but the author could get a pretty good result by adding the oxalic acid treatment further to them.
The oxalic acid treatment is considered to help the decorizing effect of Fuller's earth treatment, but it seems to have a close relation with acid value after the alkali treatment.View full abstractDownload PDF (438K) -

JOURNAL FREE ACCESSThe examination on the decolorizing ratio in each stage of the rice bran oil refining process shows the following result.
The decolorizing ratio produced by the treatment with Fuller's earth is the largest; that by the treatment with caustic soda the next; and that by the treatment with oxalic acid is the smallest. Of these three ratios the first and the third show the tendency to be proportional to the acid value of the alkali treated oil, and the second shows the tendency to be inversely proportional to that.
The examination accounts for the necessity to lower as much acid value of the alkali treated oil as possible, in order to raise the total decolorizing effect.View full abstractDownload PDF (429K) -

JOURNAL FREE ACCESSThe press-defatted seeds of “Haze” (Rhus succedenea) were separated into the kernels and hulls, and their digestibilities by rats were determined.
The digestibility of the kernel powder was very low, namely: this for Organic matter Protein, Fat, Pentosan and Nitrogen free extract was found to be 15, 25, 95, 6, and 8%, respectively.
The main constituents of the kernel were cellulose and hemicellulose or pentosan (xylan), and only 22% of the hemicellulose were hydrolysed by taka-amylase.
The digestibility of the hull powder was generally higher than that of the kernel, namely: this for Organic matter, Glucide, Protein and Fat was found to be 45, 73, 12, and 47%, respectively.
The culculated available energy values were as follows: Kernel powder, 71 Cal. per 100g; and hull powder, 152 Cal.View full abstractDownload PDF (576K) -

JOURNAL FREE ACCESSTo estimate the loss of lysine in bread during baking, the bread baked with flour to which was fortified 0.5 and 0.25% of lysine-monohydrochloride, DL and L isomers, respectively, were conducted to determine the remaining lysine. The microbiological assay method was employed throughout the study, wherein lysine determination regarding both the preparates of acid hydrolysates and water extracts of dough and bread was performed.
No destruction of lysine was found to occur during fermentation, whereas was found a considerable destruction which is due to baking. In the bread baked with flour DL-form of lysine added, the loss of L-isomer was found to be about 30%, on the other hand, in that from L-lysine added flour, lower range of loss, amounting about 10% was observed. And in the latter bread the loss estimated from total and free Llysine showed no accordance, the discrepancy being discussed.View full abstractDownload PDF (789K) -
On the toxicity of fish oil heat-polymerized in the presence of the airNoboru Matsuo1958 Volume 10 Issue 5 Pages 255-259

JOURNAL FREE ACCESSIn the previous paper, the author reported that cuttle fish oil heat-polymerized in a stream of CO2 for 10 hours at 250°C, was toxic to rats and that the cyclic ethyl ester separated from the this treated oil by the method of urea-adduct forming process was highly toxic to rats while the straight chain ethyl ester non-toxic. In this paper, quite the similar results are presented on cuttle fish oil polymerised by heating in the presence of the air for 10 hours at 225±10°C.
The oil contains a quite small amount of peroxide, but exerts a strong toxic action to rats due to cyclic ethyl ester brought about by polymerization.View full abstractDownload PDF (1083K) -

JOURNAL FREE ACCESSThe condition of taking nutriment among students taking lessons in the building of the Faculty of Science, Tokyo Metropolitan University was investigated.
Kinds and rough amounts of foods taken by them during successive three days between the 21st (Mon.) and the 26th (Sat.) May, 1956 and between the 3rd (Mon.) and the 8th (Sat.) June, 1957 were recorded by themselves, and the nutrition values of those foods were calculated by our using the Table of Japanese Standard Components of Food Materials.
31 students (containing 5 women) in 1956 and 62 students (containing 10 women) in 1957 were selected as objects of this investigation. The result was compared with the standard values, and it was showed that the values in 1957 vised to some degree compared with those in the previous year, but generally they were behind the standard values, and especially the amounts of Calcium and Vitamins reached to about only 1/3 of the standard values, and generally the amounts of foods from animal matter were insufficient.View full abstractDownload PDF (357K) -
