[The effect of administration of vitamin E on levels of serum immunoglobulins and levels of phagocytic activity].
The effect of peroral administration and parenteral implantation of vitamin E was followed as exerted on the concentration of total serum immunoglobulins and phagocytic activity of blood leucocytes in calves. Twelve calves at the age of maximally 14 days with the average live weight of 41.2 kg were included in an experiment with peroral administration; six of them were given Combinal E (Tocoferolum aceticum 40 mg in 1 ml) at a dose of 20 mg tocopherol acetate per kg live weight. Sixteen calves at the age of three months and with the average live weight of 112.6 kg were included in the second trial. The Erevit preparation was implanted intramuscularly to eight calves at the same dose as in the first experiment (Tocoferolum aceticum 300 mg in 1 ml solutions oleosae). The animals of control groups in both experiments were administered sunflower oil as a placebo, namely at the same amount as the above-mentioned preparations (no oil treatment for peroral administration, heat and pressure treatments of oil for intramuscular implantation). All the preparations lead to a significant increase in vitamin E concentrations in the blood plasma of calves in both experiments, the highest average level being recorded in 24 hours after administration (8.05, and/or 5.51 mumol/l; Tabs. I and IV). The level of total serum immunoglobulins was not influenced by vitamin E supplementation; this level remained below the physiological range of values in calves with peroral administration during the whole time of observation.(ABSTRACT TRUNCATED AT 250 WORDS)
