The remaining amino acids in gastrointestinal tracts were analyzed using an amino acid analyzer, and the amount of absorbed amino acids was calculated . Thirtyseven percent and 74% of injested nitrogen was absorbed 1 and 3 hours after feeding , respectively. Among the essential amino acids, Lys disappeared most rapidly from the gastrointestinal tracts , and Met disappeared most slowly. Thr and His belonged to the intermediate group . Similar experiment was carried out with a diet containing an amino acid mixture simulating rice protein . The absorption of nitrogen from this diet was 37 and 70 percent, 1 hour and 3 hours after feeding , respectively. The rate of absorption of each amino acid in this amino acid mixture was different from that of the previous experiment with rice protein. The rate of Lys, Met and Thr was intermediate , that of Arg and His was rapid. The absorption of Tyr was extremely slow. Relation to the supplemental effect of amino acids to rice protein was discussed.","PeriodicalId":86661,"journal":{"name":"[Eiyo to shokuryo] Journal of the Japanese Society of Food and Nutrition","volume":"11 1","pages":"504-507"},"PeriodicalIF":0.0,"publicationDate":"1968-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76435836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our studies have given conclusive evidence that XA is related to the development of human diabetes, a disease generally attributes to an inadequate food intake. Evidence also suggests that there is a close relationship between animal and human diabetes.Experiments have shown that XA is a substance produced in the body as a result of intake of excess of the sodium salts of fatty acid (representing fat) and tryptophan (representing animal protein).Taking into consideration the chronic nature of human diabetes, we then studied the development of chronic diabetic symptoms in rat caused by accumulative effect of XA produced in the body when vitamin B6 deficient diet or excessive fat and tryptophan diet was administered for a long period. Then the pancreatic tissue of these rats was examined histologically. A decrease of stainability, a decrease in granules, much vacuole formation, and collapse of the protoplasm were noticeable in the β-cells of the islets of Langerhans.We then examined fairly large amount of XA in the urine of many diabetic patients by the partition paper chromatographic method. These is an undeniable etiological relationship between free XA and human diabetes since a fairly large amount of XA in a free form present in the urine was invariably present in the urines of diabetic patients.Murakami, one of our co-worker, recently showed that XA formed a binding complex with insulin. We have observed XA bound with insulin in human serum. XA-insulin complex showed a new fruorescence spectrum. The hormonal activity of XA-insulin complex was markedly decreased.From these results we may suggest that experimental diabetes in the presence of XA may be induced by the following mechanism:","PeriodicalId":86661,"journal":{"name":"[Eiyo to shokuryo] Journal of the Japanese Society of Food and Nutrition","volume":"19 1","pages":"155-162"},"PeriodicalIF":0.0,"publicationDate":"1968-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73932710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
