(2) Influence of Lysine Supplementation to the Gluten Diet on Distribution of 14C-Threonine and 3H-Leucine in Several TissuesYoshiki Kobatake, Shiro Niizeki, Masako Iwaya, Einosuke Tamura1974 Volume 32 Issue 4 Pages 149-154

JOURNAL FREE ACCESSLysine supplementation to the gluten diet is known to be accompanied by a significant drop in the plasma free threonine concentration of the rat. This study was conducted to determine the cause of its phenomenon. The results obtained follows;
1. Two groups of four young rats were fed for four weeks the 20% gluten diet supplemented with or without 5% L-lysine·HCl. Weight gain of lysine supplement group was three times higher than that of non-supplement group. Free threonine concentrations in serum, muscle, liver, and small intestine were significant lowered when the gluten diet was supplemented with lysine. But most other amino acid concentrations in serum and tissues showed no marked changes.
2. Ratios of acid soluble radioactivity to protein radioactivity from 14C-threonine and 3H-leucine injected intraperitoneally decreased in muscle, liver and small intestine of rats on a diet supplemented with lysine. These ratios for 14C-radioactivity (except 3H-radioactivity) in muscles of either supplemented or non-supplemented rats were significantly higher than that in other tissues.
3. The results suggest that the marked decline of free threonine levels in serum and tissues caused by feeding lysine supplement gluten diet may be due to increased incorporation of threonine into protein of muscle and any other organs, and accerelated transport of threonine from organs to muscle.View full abstractDownload PDF (6810K) -

JOURNAL FREE ACCESSThe hypocholesterolemic effects of methylcellulose, carboxymethylcellulose, carrageenan, propyleneglycol alginate and crude konjac mannan (prepared from the tubers of Amorphophallus konjac) were examined in rats fed a hypercholesterolemic diet containing 1% cholesterol and 0.25% bile salts.
1. It was found that 5% propyleneglycol alginate, a synthetic derivative of alginate, markedly decreased the high level of serum cholesterol which was introduced by the hypercholesterolemic diet. However, propyleneglycol itself did not any hypocholesterolemic activity or depressing effect in liver cholesterol.
2. The hypocholesterolemic effects were reconfirmed in the rats fed diets supplemented with 5% carrageenan or 5% crude konjac mannan. It was shown that the hypocholesterolemic activities were different with different sources and preparations of these two polysaccharides.
3. Other materials such as methylcellulose or carboxymethylcellulose, when fed under similar conditions, did not show any hypocholesterolemic effect.View full abstractDownload PDF (6676K) -

JOURNAL FREE ACCESSFor six years (1968-1973), we have carried out a caloric and nutritional survey of female students living in our dormitory.
The findings are as follows:
(1) The students were taking almost enough nutrients to meet the requirements recommended according to their age. The percentage of cereals to the total calories was 59.0%; the animal protein contained in the food was improved in both quantity and quality. The percentage of fat to the total calories was 16.8%.
(2) Among the other nutrients, more vitamin A, vitamin B1, vitamin B2 and iron should be taken.
(3) Of each food group an adequate balance in the average intake was maintained though milk and fruit were inadequate.
(4) Seventy-two percent of the students usually take a snack between meals which consisted of a very high percentage of sweet foods: cookies 50.0%, candies 23.8%, cakes and nuts 13.8% etc.View full abstractDownload PDF (8422K) -

JOURNAL FREE ACCESSAn investigation of the time consumed in daily life duties and the diets of senior high school students living in cities was carried out to clarify the actual condition of the nutrient intake of growing students and also the relationship between the caloric intake and calories expended. It was concluded:
1) Both the coloric intake and the calories expended were higher in male students, and a great difference between boys and girls was found. The difference was larger as compared with the case of pupils infants shown in the previous report.
2) From the time study of daily life duties no difference in calories expended between boys and girls could be found in hours for sleeping and study at school. Girls needed plenty of time in helping work at home and dressing, and the boys for sportsclub at school. Therefore, the expenditure of boys was higher.
3) Comparing the caloric intake and clories expended both boys and girls consumed more energy in the afternoon. As the result, the importance of food quality, especially in lunch was shown.View full abstractDownload PDF (6647K) -

JOURNAL FREE ACCESSPatients of vitamin A deficiency are frequently found in the Southeast Asia. Aflatoxin, a kind of toxin contained in some tropical foods, affects in the inhabitants of the same area. In this experiment, we tried whether the biosynthesis of vitamin A is inhibited by aflatoxin or not. Male rats, weighing about 70g, were administered 4mg of aflatoxin B1 per kg body weight intraperitoneally. Rats were killed and their livers were removed, homogenized by Potter's homogenizer. Liver homogenate obtained was centrifuged at 3, 000r.p.m. and the supernatant was used as enzyme solution. Reaction mixture consisted of 0.8ml of enzyme solution, 1mg of β-carotene. 10μmoles of glutathione, 30μmoles of nicotinamide, 12μmoles of sodium taurocholate, 1mg of α-tocopherol and 200μmoles of potassium phosphate buffer, pH 7.7. After 60min incubation at 37°, the reaction mixture was shaken with chloroform. Vitamin A synthesized from β-carotene was extracted into chloroform. Amount of vitamin A was assayed spectrophotometrically. The results of experiment showed that aflatoxin inhibited the conversion of β-carotene into vitamin A. It is concluded that the chronic intoxication of aflatoxin has a tendency to cause vitamin A deficiency.View full abstractDownload PDF (3352K) -
