In this extract, thin layer and paper chromatography showed the presence of a ketoheptose, the mannoheptulose, in amount of 0.1 g/ml extract or 1.1 g/100 g fresh pulp. Physiological experiments were performed with avocado extract and comparatively with a sample of commercial mannoheptulose. Six-month-old rats were given by stomach tube 10 mM CaCl2 solution (+ 45Ca) containing a carbohydrate. Depending on the group, the carbohydrate was 20 and 100 mM glucose (control), D-mannoheptulose 200, 100, 50 and 25 mM, avocado extract concentrated or diluted 1/2, 1/4, 1/8, 1/16. Blood samples were taken at different times after the administration and plasma radioactivity was measured. Rats were sacrificed at 24 hours; femur and axis radioactivity was used as a measure of calcium absorption. Both mannoheptulose and avocado extract were potent on calcium absorption. This absorption increased progressively with sugar concentration, in mannoheptulose and avocado groups. The interpretation of these results was discussed and also their application to the Nutrition in tropical and subtropical countries.","PeriodicalId":75504,"journal":{"name":"Annales de la nutrition et de l'alimentation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18239288","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}

Free fatty acid, triglyceride and cholesterol levels in the plasma were significantly increased at 31 days after tumor implantation. Blood glucose and glycerol levels remained normal, while uric acid concentration in the blood was significantly decreased. The concentrations of the serum lipoproteins were significantly increased, while, only small changes in the distribution of the serum lipids and the composition of the lipoproteins were observed. Following stimulation of isolated adipose tissue cells with ACTH, the lipolytic response and the accumulation of cyclic AMP was higher in cells derived from the rats with the tumor, although the accumulation of cyclic GMP was not different from control adipocytes. Further, when the isolated adipose tissue cells were stimulated with dibutyryl cyclic AMP no difference was observed between the control and tumor bearing groups. Clofibrate administered in the diet resulted in a complete elimination of the tumor effect on serum triglycerides and to a great extent prevented the rise in serum cholesterol. The tumor-induced increase in the concentration of the high density lipoproteins was not affected, but the elevation of the d less than 1.063 lipoproteins was not affected, but the elevation of the d less than 1.063 lipoproteins was partially reversed. The increased lipolytic response and accumulation of cyclic AMP following stimulation by ACTH was not altered in adipocytes derived from tumor bearing rats. However, clofibrate treatment resulted in a significantly greater accumulation of cyclic GMP in fat cells stimulated with ACTH from both control and tumor bearing rats. Clofibrate in the diet did not alter the levels of GH or prolactin or serum lipids in the control rats nor were the elevated hormone levels of the tumor bearing rats changed.","PeriodicalId":75504,"journal":{"name":"Annales de la nutrition et de l'alimentation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11439847","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}

Experiments were carried out on Sprague-Dawley rats. The ceruloplasmin level of control animals and vitamin A - deficient rats was determined An average increase between 22 and 33% was observed in the animals with vitamin A deficiency, the highest levels being observed in the females. These results are in agreement with Peterson's previous work. A second type of experiment was carried out to confirm these results. The rats were raised in a copper-deficient diet and the vitamin A level was regularly determined. In these conditions serum and liver levels of vitamin A are normal and do not vary, ceruloplasmin level is zero; however apoceruloplasmin is still being synthetized : Nevertheless at the ultime state of the deficiency vitamin A level decreases while apoceruloplasmin increases. These results raise the following question. Could the relationship between ceruloplasmin and vitamin A be possibly due to an inflammatory state in vitamin A deficient rats. In this respect a third series of experiments were undertaken and are in progress; the vitamin A and ceruloplasmin levels are regularly determined.","PeriodicalId":75504,"journal":{"name":"Annales de la nutrition et de l'alimentation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11736333","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}

Wistar weanling rats have been fed for 16 weeks semi-synthetic diets containing 15% of lipids by weight, in which the fatty acids under study (brassidic, erucic elaidic) ranged to 40%. Although caution has been taken to optimize the digestibility of brassidic acid (interesterification of the lipid mixture, reduced level of calcium in the diet, addition of monoglycerides), it remains lower that of erucic acid. However, because of different levels of food consumption, the absorbed amounts of the two isomers are about the same. With a high dietary supply of linoleic acid, the dietary monoenes (C 22:1 or C 18:1), cis or trans) do not induce great changes in the weight gain of the rats, when adjusted to food consumption; linoleic acid subdeficiency lowers this adjusted weight gain, except when the diet contains oleic acid as the only monoene. These effects do not parallel those observed on the absolute growth of the rats. The trans monoenes, and to a lesser extent, erucic acid, induce an increase of liver weight (adjusted to body weight). The light microscopic histological study of the heart does not reveal any difference between the brassidic acid fed-rats and those fed the C 18:1 monoenes (elaidic, oleic). In contrast, erucic acid induces definite lesions of the myocardium. The dietary level of linoleic acid has little influence on the incidence and the severity of the lesions. The effects of these dietary fatty acids on the lipid contents and fatty acid compositions of different organs will be reported in a second paper.","PeriodicalId":75504,"journal":{"name":"Annales de la nutrition et de l'alimentation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11756279","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}
