Study I was a prospective one in which 23 pregnant women ultrasonically diagnosed as having small fetuses were compared with 22 women with large fetuses. Maternal plasma zinc concentrations pre- and post-35 weeks gestation were significantly higher in mothers of small than in mothers of large infants. Twelve women with normal pregnancies participated in study II. Biochemical data obtained in maternal plasma during the third trimester of pregnancy, including total, albumin-bound and alpha 2-macroglobulin-bound plasma zinc concentrations and plasma copper concentration were compared with infant anthropometric data at birth. The results indicated significant negative correlations between maternal plasma zinc and albumin-bound zinc concentrations and plasma copper concentration in the third trimester of pregnancy and mid-arm circumference and ponderal index. The results of these studies, in the light of other data reported for primates and humans, suggest the need for a more extensive investigation of the relationship between maternal circulating zinc and copper concentrations and fetal growth.","PeriodicalId":13078,"journal":{"name":"Human nutrition.

Human milk contains relatively high amounts of nucleotides which are practically absent in cow's milk and milk formulas. These compounds have been related to normal growth and cellular immunity in animals in early life. The aim of this study was to investigate the effects of dietary nucleotides on the plasma fatty acid pattern in term neonates during the first month of life. Twenty-six infants were fed human milk, 35 a milk formula and 23 the same formula supplemented with cytidine, adenosine, guanosine, uridine and inosine 5'-monophosphates in similar quantities to those determined in human milk. Plasma polyunsaturated fatty acids with more than 18 carbons of the omega 6 family were significantly increased in infants fed with the nucleotide-supplemented milk formula with respect to those fed the milk formula, whereas no differences could be detected between the human milk-fed and the nucleotide milk formula-fed ones. These results suggest that dietary nucleotides may be involved in the conversion of linoleic acid to longer chain polyunsaturated fatty acids during early life.","PeriodicalId":13078,"journal":{"name":"Human nutrition.

The magnitude of malnutrition in the study population vis-à-vis a middle-income reference group was assessed by comparing the baseline data on the two groups. Effects of time-related variables such as lactation and season were also examined by a cross-sectional analysis of the baseline data on the study population. In all three centres the majority of the study population suffered from biochemical riboflavin and/or pyridoxine deficiency even before initiating contraception. Lactation appeared to have an effect on the vitamin status, which varied among the different populations. Seasonal effects were seen, but showed inconsistent trends in the three centres. Both the oral contraceptive pills and DMPA tended to increase serum vitamin A and blood folate. The thiamin, riboflavin and pyridoxine status of the women who were already deficient did not deteriorate further with the use of hormonal contraception, as judged by enzyme saturation tests. Some deterioration in the riboflavin status of the normal women of Hyderabad was seen with the use of oral pills. Women who were biochemically deficient prior to the use of oral contraceptives tended to show some improvement in B-vitamin status, over the 1-year period of hormonal contraception.","PeriodicalId":13078,"journal":{"name":"Human nutrition.

{"title":"Dietary antioxidants and chronic pancreatitis.","authors":"P Rose, E Fraine, L P Hunt, D W Acheson, J M Braganza","doi":"","DOIUrl":"","url":null,"abstract":"Fifteen patients with idiopathic chronic pancreatitis (aged 17-78 years), who had not altered their diet since their first symptoms, completed 7-d weighed dietary records at home. The computed information was compared with that from 15 age- and sex-matched volunteers. Attention was focussed on the intakes of antioxidants and unsaturated fatty acids. The patients ingested less selenium, vitamin E, vitamin C and riboflavin than did controls (P less than 0.001, P less than 0.02, P less than 0.001 and P less than 0.05 respectively, using paired t-tests): selenium was by far the best discriminator on step-wise analysis. When the selenium intakes were examined alongside the results of theophylline tests--which reflect cytochromes P450 activities and, thereby, provide an index of antioxidant demand--a line of discrimination separated the majority of patients (with faster drug clearances and lower selenium intakes) and controls. There were no differences in the intakes of individual unsaturated fatty acids, C14:1 through to C24:6, between the two groups. However, amongst six subjects in the overlap zone, three with chronic pancreatitis habitually ate greater amounts of highly unsaturated fatty acids C20:4 to C24:6 inclusive (1970, 1049, 750 mg/d) than did three controls (329, 320, 82 mg/d). Animal experiments show that suboptimal intakes of dietary antioxidants and/or excessive intakes of highly unsaturated fatty acids and/or induction of cytochromes P450 facilitate peroxidation of cellular lipid membranes by free radicals. Our dietary data, taken in conjunction with pharmacokinetic data, thus suggest that a similar situation--favouring lipid peroxidation--may underlie human chronic pancreatitis.","PeriodicalId":13078,"journal":{"name":"Human nutrition.
