摘要:

AbstractThe results of animal and epidemiological studies suggest commercially salted infant foods may predispose infants to hypertension. Testing this hypothesis, two groups of black male infants were fed identical foods with and without added salt for 5 months starting at 3 months of age. These diets, which provided 1.93±0.10 and 9.25±0.05 mEq Na/100 kcal, did not result in a significant difference in blood pressure at 8 months or 8 years of age. Blood pressure was significantly correlated with weight factors, particularly at 8 years, but not with Na intake, Na or Na/K excretion or plasma renin at 8 months.Significantly increased sodium and potassium excretion was noted on the salted diet and significantly increased aldosterone excretion was noted on the unsalted diet. A 6% expansion in extra‐cellular fluid volume for the high sodium group was statistically significant but was not correlated with blood pressure or urine volume and did not result in edema or increased weight.There was no indication that the salted foods imprinted a preference for salt at 8 years.It was concluded that a salt intake representing the 99th percentile of sodium intake by U.S. infants in 1969 had no hypertensive effect in infancy or at 8 years of age. Nor did it imprint a preference for salt at 8 ye

Abstract.Holm, G. and Björntorp, P. (Department of Medicine I, Sahlgren's Hospital, University of Göteborg, Göteborg, Sweden). Metabolic effects of physical training. Acta Paediatr Scand, Suppl. 283: 9, 1980.—Effects of physical training on factors associated with diabetes mellitus and its increased risk for cardiovascular disease are reviewed. Plasma insulin levels are decreased by training particularly in obesity and glucose tolerance seems to be improved. Training leads also in general to diminished body fat, but this is not obligatory for the plasma insulin decrease. There are no changes in concentrations of amino acids growth hormone or catecholamines, which can explain the insulin decrease. Cortisol is decreased the days after an acute exercise as well as after training in parallel with the plasma insulin decrease. The cortisol decrease may lead to changes in insulin receptor density in tissues leading to increased insulin sensitivity. The insulin decrease seems to be due to both a decreased production (to about 2/3) and an increased clearance (to about 1/3). Physical training leads to a decrease in plasma triglycerides and to a decrease in blood pressure. All these effects of physical training seem to be beneficial in the treatment of diabetes mell

Abstract.Gmelig‐Meyling, F., Dollekamp, I., Zegers, B. J. M. and Ballieux, R. E. (University Children's Hospital “Het Wilhelmina Kinderziekenhuis” and Department of Clinical Immunology, University Hospital, Utrecht, The Netherlands). Lymphocyte subpopulations in neonates, young children and adults as detected by six cell surface markers. Acta Paediatr Scand, 69: 13, 1980.—In this study, six surface marker tests were performed on lymphocytes from normal individuals of three age groups: neonates, children from 0 to 2 years of age, and adults. Determined were the proportions of T cells binding sheep red blood cells, of B cells carrying surface immunoglobulins or binding mouse red blood cells, and of lymphocytes bearing receptors for IgM, for IgG or for complement. The T cell percentage appeared to increase with the age; the percentage of B cells was highest in the children's group, as determined by both marker tests. Neonates had a much lower proportion of IgM‐receptor bearing cells than older individuals. The variation in the percentages of T cells and of IgM‐receptor bearing cells in the young age groups was relatively large as compared to adults. The significance of these observations is discussed; they may be of value for the proper evaluation of results obtained in diagnostical tests on neonates and yo
