title: [Further study of the role of vitamin A in immunologic reactions (observations in volunteers)].
abstract: Studies made on volunteers who received vitamin A for a week have demonstrated that the content of peripheral blood lymphocytes increased, which was followed by a relative and absolute increase in the content of B lymphocytes and a rise in the number of T cells in the peripheral blood. An increase in the complementary activity of the blood serum and an increase in IgA content in it were also recorded. After a month the majority of the parameters under study returned to normal.
