[Immunomodulating action of fat-soluble vitamins after intense physical loading at low ambient temperatures].

Introduced separately, preparations of the fat-soluble vitamins A, E and K decreased the expression of changes in the immunological reactivity and nonspecific resistance of Wistar rats after a 4-h swimming in water at a temperature of 10 +/- 2 degrees C. Joint administration of the vitamin preparations A + E or A + K normalized both the the immunological reactivity and nonspecific resistance of rats after cold swim test, while the joint introduction of vitamins E + K produces no such effect.
