[Quantitative characteristics of the T- and B-systems of immunity in healthy persons of different age groups].

The authors carried out a complex immunomorphological study of the peripheral blood lymphocytes in 160 healthy persons of different age groups. The tests of spontaneous and complementary rosette formation of lymphocyte blasttransformation with PHA were used, assessing it by the H3-thymidine incorporation, lymphocyte straining by Coon's direct and indirect methods for detection of surface immunoglobulin receptors; G, A, and M immunoglobulins blood serum content was studied by Mancini's method. Mean indices characterizing the T- and B-populations of lymphocytes in persons of different age were calculated on the basis of these studies.
