The Vitamin B1 and Vitamin B2 ContentsAkira Kariyazono1973 Volume 31 Issue 2 Pages 49-51
Published: March 25, 1973
Released on J-STAGE: October 29, 2010
JOURNAL FREE ACCESSQuantitative analysis was carried out to determine the vitamin B1 and vitamin B2 contents on Castilla Cake in Nagasaki. The following results were obtained.
Samples I, B and F contained 0.065, 0.056 and 0.105mg% B1 respectively. Samples I, B and F contained 0.077, 0.043 and 0.031mg% B2 respectively.
Among samples I, B and F, sample F contained the largest amount of vitamin B1 and sample I had the highest content of vitamin B2.View full abstractDownload PDF (2901K) -
Free Amino Acids and the Amino Acid Ratio of Plasma in Children with Sub-Clinical Protein DeficiencyEinosuke Tamura, Nobuo Matsuno, Masako Iwaya, Shiro Niizeki, Hiroshi W ...1973 Volume 31 Issue 2 Pages 52-56

JOURNAL FREE ACCESSIn order to compare the plasma amino acid ratio recommended by Whitehead plasma tyrosine and valine levels and the Phe/Tyr ratio with those of healthy children, 24 subjects of 2-4 years old from 3 districts in Iwate Prefecture were selected. The children in these districts were in a sub-optimal state of protein nutrition as is evident from their detardation of growth, especially in Iwaizumi district where more than 15% were below the Japanese standard in body weight. A correlation between those estimations and the change in body weight was observed. The average amino acid ratio in Iwaizumi showed 2.1, whereas in case of healthy children the ratio was 1.7 in average and in the other 2 districts remarkable differences were not observed from that of healthy children.
The amino acid ratio was found to be related to the change in body weight, with a coefficient of -0.75 while the Phe/Tyr ratio and valine content in plasma were somewhat less well correlated with the change in body weight, whereas the tyrosine content of the plasma was only slightly correlated.
The results show that Whitehead's method is simple and widely applicable in field work and may be useful for the early detection of sub-clinical protein deficiency.View full abstractDownload PDF (5082K) -
II. Response of rat liver phenylalanine hydroxylase to dietary change and hormonal treatmentYoshiki Kobatake1973 Volume 31 Issue 2 Pages 57-62
Published: March 25, 1973

JOURNAL FREE ACCESSThe effects of nutritional and hormonal treatments on the activities of rat liver phenylalanine hydroxylase (Phe H) were studied. When a non-protein diet was substituted for the high protein diet, Phe H activities fell rapidly and remained constant from Day 7, whereas when rats were starved for 10 days, Phe H activities were slightly decreased. In case of protein-depleted rats fed a 15% casein diet for 8 days, Phe H activities were again increased. However, excess feeding of tryptophan or phenylalanine delayed the return of Phe H activity to the control level. Neither glutamic acid, lysine nor threonine had effect when fed in excess. In rats fed an amino acid diet devoid of only phenylalanine, recovery of Phe H activity was inferior to that of rats fed a complete diet, but only slight recovery of Phe H activity was observed in rats fed a phenylalanine-tyrosine deficient diet. Doses of cortisone did not respond to Phe H in the liver of intact and adrenalectomized rats. Alloxan diabetic treatment to rats also did not have effect on this enzyme activity.View full abstractDownload PDF (6901K) -

JOURNAL FREE ACCESSThe relationship between the plasma amino acid ratio recommended by Whitehead and the weight gain or protein level in the diet was studied using male rats weighing about 90g. The animals were given diets containing graded amounts of casein for 9-41 days. The amino acid ratio, estimated by a modification of Whitehead's method, was found to be closely correlated with the weight gain and also the dietary protein level.
When the animals were given either a rice or wheat flour diet supplemented with lysine and threonine, a close relationship between the amino acid ratio and weight gain was also observed.
In our animal experiments, the hydroxyproline index which could be related to the incidence of the clinical signs of Kwashiorkor was also found to correlate well with the amino acid ratio and weight gain.View full abstractDownload PDF (5579K) -

JOURNAL FREE ACCESSThis study was carried out to investigate the relationship between the amount of caloric intake and caloric consumption of farmer's wives. Forty homes selected from Anjo City, Aichi Prefecture were served for this purpose.
The scope of this survey which was conducted in September 1972, is centred on food intake conditions and working hours. First, professional farmers and side-working farmers were divided into two groups, respectively. The caloric intake and consumption was computed and comparatively discussed.
The caloric consumption of both the professional farmers and the side-working farmers were around 2300 cal. As working hours of the professional farmers were long and the R. M. R. high, their caloric intake ran short of 302 cal. on the average.
In regard of the intake of nutritive elements the professional farmers were found to be still lacking in protein, fat and vitamin A, B1 and B2.
The number of professional farmers will increase along with the modernization of agriculture so that giving these people advise in concern of energy will gain more and more importance.View full abstractDownload PDF (6540K) -
The Amino Acid Composition of Protein Contained in Lunch Supplied in June, 1971 by the Central Preparation SystemTsutomu Yoshida, Mitami Endo, Yoshiyuki Suzuki, Yukihiro Yoshida1973 Volume 31 Issue 2 Pages 75-80
Published: March 25, 1973

JOURNAL FREE ACCESSPrevious reports have dealt with the nutritional value of protein contained in lunch individually prepared (“individual preparation system”) in each school.
In this report, the protein content and the nutritional value of protein of elementary school lunch prepared by the central preparation system which delivered lunch to each individual school were studied. Centers C and D, located in two different districts in the Santama District of Tokyo were selected in June, 1971.
The results were as follows:
1) The intake of protein, animal protein and essential amino acids in centers C and D was found to be satisfactory.
2) The protein score was 76 in centers C and D. The first limiting amino acid for the protein score in both centers was found to be the sulfur-containing amino acids.
3) The E/T ratio was 2.49 in center C and 2.45 in center D.
4) The egg score was 67 in centers C and D. The first limiting amino acid for the egg score in both centers was the sulfur-containing amino acids.
5) The human milk score was 87 in center C and 88 in center D. Tryptophane was the first limiting amino acid for the human milk score in both centers.View full abstractDownload PDF (6360K) -
