Vitamin D-binding protein (DBP) participates in the actin scavenger system, it is a carrier of vitamin D and its derivatives, it manifests the capacity to bind mainly monounsaturated and saturated fatty acids, it binds to the surface of several cells and enhances chemotactic activity of C5a of the complement. The present study was aimed at answering the question whether serum DBP level in mares is related to levels of this protein in colostrum and in serum of its progeny. For this purpose, sera from 77 mares, colostra from 72 mares and sera from 69 Thoroughbred foals were collected. Mother’s age, number of deliveries experienced in the past, month of delivery, feeding of foals with colostra were recorded. Blood of the foals was sampled from the umbilical vein during delivery (0h) and 36-48 h after delivery from the external jugular vein, colostra of the mares were obtained after delivery and blood of the mares was sampled 36-48 h after delivery. Concentration of DBP was estimated by a self-designed ELISA. In the present study, DBP concentrations in newborn’s serum were found independent of their concentrations in mother’s serum, her age and number of parities experienced in the past. Colostrum DBP level was found to be lower than that in the mare’s serum and was not correlated to the concentration of this protein in mare’s serum. There was no effect of colostrum feeding on DBP level in the foal serum. These results indicate that serum DBP concentration in newborn foals depends on factors which act directly on the foal. Because of the lack of correlation between plasma and colostrum concentrations of DBP, it can be assumed that DBP is synthesised in the mammary gland and/or specific transport mechanisms exist in the mammary gland.

Vitamin E together with selenium-dependent glutathione peroxidase and catalase form the main antioxidative system of human cells. Vitamin E is indispensable nourishment component, since it cannot be synthesized by human cells. Therefore appropriate diet is an important factor determining antioxidave abilities of the organism. The aim of the study was to estimate feeding type influence on vitamin E concentration in blood plasma of infants hosptalized in Infants' Department. Study group consisted of 42 children (18 girls and 24 boys) aged 1 - 12 months, hospitalized due to pneumonia, otitis media, urinary tract infection, diarrhoea or sepsis. Children were divided into three groups concerning the type of feeding: 1. children feed with modified milk-30 (71.43%), 2. children feed with mother's milk-7 (16.67%), 3. children feed in mixed way - 5 (11.9%). Vitamin E plasma concentration was estimated by fluorometric method modified by Hansen and Warnick. Results were given in μg/mL. Statistical analysis was performed using NIR post-hoc test. P<0.05 was considered as statistically significant. We found statistically higher vitamin E concentration in blood plasma of infants fed only with mother's milk (25.28±10.33, range: 11.4-40 μg/mL) compared to the children fed with modified milk (18.56±6.74, range: 7.6-30 μg/mL) and these fed in mixed way (16.15±5.14, range: 11.8-23.5 μg/mL). Vitamin E concentration was the highest in blood plasma of infants fed only with mother's milk, which showed beneficial influence of breast feeding on vitamin E plasma concentration in infants with infection.

W patologii zmian miażdżycowych poważną rolą odgrywa niedobór witamin antyoksydacyjnych. Podstawowym źródłem tych witamin powinny być spożywane racje pokarmowe. Celem przeprowadzonych badań było ustalenie na ile całodzienne racje pokarmowe kobiet w wieku podeszłym z chorobą niedokrwienną mięśnia sercowego pokrywają zapotrzebowanie na te witaminy oraz czy wielkość spożycia koreluje z ich surowiczym stężeniem? Stwierdzono niską żywieniową podaż witamin E, C oraz ß-karotenu w racjach pokarmowych chorych, która nie była statystycznie istotnie związana z ich surowiczym stężeniem.

Deficiency of antioxidant vitamins play an important role in the pathology of atherosclerotic changes. Proper nutrition should be the main source of these vitamins. The aim of the study was to assess the intake and analyse serum levels of vitamins: E, C and β-carotene, and to relate the results to the actual recommeded dietary intakes for elderly women. The correlation between serum levels of vitamins and their intakes was also determinated. The consumption of vitamins C, E and ß-carotene (30-60, 40 and 15-30%, respectively, in relation to the average requirement) was found to be low. There was no statistically significant correlation between vitamin intake and their serum levels. The abnormalities in nutrition, linked with low consumption of vitamins confirm the necessity to provide the elderly women with information on healthy nutrition. Some of the elderly patients require pharmacological suplementation with witamin E and ß-carotene preparations.
