In order to investigate the breast milk composition over a prolonged period of lactation milk samples from 33 women from a rural area of the Ivory Coast were analyzed once monthly. Analyses of lipid components of protein were performed in 2 longitudinal studies covering 23 months of breast feeding. The composition stayed essentially constant over the 23 months of lactation except for a decrease or protein concentration during the first 6 months, a rising trend of myristic acid and a falling trend of oleic acid. For the first 5 months the infants grew well on breast milk alone, but thereafter their growth curves were unsatisfactory as judged by Western standards. The mothers' weight for height stayed constant. In a cross-sectional study, additional determinants were performed: aminograms, lactose, calories, iron, copper, manganese, zinc, and vitamin E. All data were compared with those of the literature; lauric and myristic acids were higher, and total lipids and polyunsaturated fatty acids were lower than those published for Western countries. Plasma composition of the mothers showed lower levels of albumin, lipids, and polyunsaturated fatty acids as well as blood hemoglobin.

The results of a study on the effect of dietary selenium administered with vitamin E on serum levels of albumin, glucose and urea nitrogen in ewes are reported. In October, at the onset of breeding, after ten months on a dystrophogenic diet, mean serum levels of albumin (g/dl), glucose (mg/dl) and urea nitrogen (mg/dl) were respectively 3.5, 52.9 and 12.8, in 65 Se-deficient ewes and 3.6, 51.7 and 14.3 in 65 Se-adequate ewes. Despite a significant difference in the serum level of urea nitrogen between Se-deficient and Se-adequate groups, no consistent effect of dietary selenium was apparent.

An experiment was conducted to study the effects of feeding a 96.8% cull pea basal ration, low in selenium (0.061 ppm) and vitamin E (7.0 IU alpha-tocopherol/kg of ration), to growing pigs with and without supplementation of selenium, vitamin E, or both. The basal ration was high in crude protein (25.2%) and contained no supplemented fat. Nine of 10 pigs fed the unsupplemented basal ration had lesions attributed to selenium-vitamin E deficiency, and 8 of these pigs died during the 160-day experiment. The deficiency was usually characterized by sudden death (with no prior signs of illness), massive hepatic necrosis, hemoglobinuric and to a lesser extent cholemic nephrosis, degenerative myopathy of cardiac and skeletal muscles, edema, icterus, and acute terminal congestion and hemorrhage. Clinical signs, deaths, or lesions attributed to selenium-vitamin E deficiency were not observed in any of the pigs fed the basal ration supplemented with as little as 0.01 ppm selenium as sodium selenite or 100 ppm alpha-tocopherol. Pigs fed the unsupplemented basal ration gained more slowly (P less than 0.01) and less efficiently and had higher serum glutamic oxalacetic transaminase (SGOT) levels (P less than 0.01) than pigs fed the basal ration supplemented with selenium, vitamin E, or both. There was no difference (P greater than 0.05) in albumin-to-globulin (A/G) ratios among dietary treatment groups. Using the criteria of this study, the minimum selenium requirement of growing pigs fed a low tocopherol cull pea diet was determined to be between 0.06 and 0.07 ppm.

The results of a comprehensive study to determine the effects of oral contraceptive agents on nutrient metabolism have been reported. The group of women using oral contraceptive agents was found to have significantly higher levels of hemoglobin, packed cell volume, serum vitamin A, total lipids, triglycerides, vitamin E, and alpha1-protein and significantly lower levels of serum and red cell folacin, vitamin B12 and albumin. The biological significance of many of these differences has not been elucidated satisfactorily.

In this survey of vitamin levels in 93 acute geriatric admissions to hospital, none had a completely normal nutritional profile. Twenty-two patients had over 50% of test abnormal and for all patients the average % of abnormal tests was 29%. The most common abnormalities were albumin, leucocyte vitamin C, vitamin E, carotene and nicotinic acid where over 50% of patients had abnormal results. Transferrin and vitamin A levels were abnormal in over 30% of patients while there was little evidence for riboflavin or thiamine malnutrition. It is postulated that an inadequate dietary intake, due to disease or to physical and mental deterioration was the most likely cause of these multiple nutritional abnormalities.

Albumin carries fatty acids and has also been suggested to act as an antioxidant. In the present work, polyunsaturated fatty acids (linoleic, arachidonic, eicosapentaenoic and docosahexaenoic acids)--but not palmitic and oleic acid--inhibited growth of human hepatoma cells in low albumin concentration (0.5%). Growth inhibition by polyunsaturated fatty acids was prevented by albumin in a dose-related manner in the range 0.7-5.0%. Albumin also protected against growth inhibition following catabolism (by lipoprotein lipase) of very low density lipoproteins. Vitamin E strongly counteracted the inhibitory effect of polyunsaturated fatty acids. Vitamin E and albumin appeared to have additive effects in protecting against growth inhibition by polyunsaturated fatty acids. Indomethacin did not greatly modify the polyunsaturated fatty acids effect. Growth inhibition by polyunsaturated fatty acids, as well as the level of thiobarbituric acid reacting substances (a measure of lipid peroxidation) in growth media, increased with increasing number of fatty acids double bonds. Vitamin E and albumin prevented both thiobarbituric acid reacting substances formation and growth inhibition by polyunsaturated fatty acids. The results suggest that the concentrations of albumin and vitamin E in the incubation medium are essential when studying polyunsaturated fatty acids effects on cell growth.

In order to assess the role of vitamin E, an antioxidant, in the treatment of uveitis, a controlled experimental study was carried out on 20 New Zealand albino rabbits with bovine-albumin-induced uveitis. In all vitamin-E-treated animals, clinical and histopathological study of the retina and uvea revealed no significant changes in comparison with those in untreated rabbits.

Nutritional status was assessed in a group of patients with Parkinson's disease. Weight loss since the onset of disease occurred in 52% of the patients and 22% had lost more than 12.8 kg. Although 67% of patients experienced eating difficulties of some kind, dietary intakes of protein and energy were not significantly lower than recommended intakes. Plasma levels of albumin (44.2 g/l vs 45.7 g/l), vitamin A (2.61 vs 2.94 mumol/l), vitamin E (22.0 vs 32.0 mumol/l), iron (15.3 vs 18.3 mumol/l) and zinc (14.2 vs 18.7 mumol/l) were significantly lower (P < 0.05) in the patients than in healthy controls. Levels of ferritin, total iron-binding capacity and copper were similar between groups. The potential significance of low levels of vitamin E and zinc are discussed in relation to oxidative stress in the pathogenesis of this disease.

Measurements of nutritionally relevant biochemical and endocrine variables were made on 60 apparently healthy children (group A) whose parents suffered from leprosy and who had been separated at the age of 4 years and brought up in preventoria. Most of the measurements were also made on a comparison group of healthy children from the same poor socio-economic class (group B). In both groups the serum concentrations of cholesterol and triglycerides were well below those found in Western populations. Almost all the children in both groups were anaemic, but serum iron and ferritin levels were satisfactory. Folate and vitamin B12 levels were measured in group A only and were low in a significant proportion. Deficiency of these water-soluble vitamins may be a cause of the anaemia. Low albumin levels were found in 40% of group A children, compared with 2% in group B. The concentrations of calcium and magnesium were lower and that of phosphate higher in group A than in B. In both groups one-third of the children had low levels of serum zinc. Fifteen per cent of group A children had biochemical evidence of vitamin A deficiency, but none were deficient in vitamin E. Levels of total T3 and total T4 were below the lower limit of normal in a substantial proportion of children in both groups. Concentrations of parathyroid hormone were increased in parallel with the low values for serum calcium. Radiological studies of ossification centres in 57 group A children showed delayed maturation in 11 cases. The relevance of these findings to previous studies of the children of lepers in India is discussed.

The concentration of alpha-tocopherol was measured in liver biopsy specimens obtained from 83 patients with alcoholic and non-alcoholic liver diseases. The mean hepatic vitamin E content (as alpha-tocopherol) was significantly lower in 23 patients with alcoholic cirrhosis (17.6 +/- 12.1 nmol/mg wet weight liver), compared with 12 patients with normal liver histology (39.2 +/- 29.7 nmol/mg, P less than 0.01). The mean serum concentration of alpha-tocopherol was lower in patients with alcoholic cirrhosis (13.9 +/- 7.0 mumol/l) than in individuals with alcoholic fatty liver (21.3 +/- 9.3 mumol/l, P less than 0.01) and patients with normal liver histology (23.4 +/- 11.6 mumol/l, P less than 0.01). A decreased ratio of serum alpha-tocopherol/total serum lipids was also observed in patients with alcoholic cirrhosis, compared with patients with normal liver histology (P less than 0.05). There was a significant correlation between concentrations of alpha-tocopherol in liver and serum (r = 0.43, P less than 0.001). Furthermore, serum alpha-tocopherol correlated with retinol (r = 0.53, P less than 0.001), selenium (r = 0.45, P less than 0.001), and albumin (r = 0.37, P less than 0.001) in serum. We suggest that the reduced content of hepatic alpha-tocopherol observed in some patients may play a role in ethanol-induced lipid peroxidation.
