[Characteristics of individual lymphocyte populations in the blood of virtually healthy persons]
The number of individual lymphocyte populations in the blood of apparently healthy persons was determined by spontaneous rosette-formation with SRBC (T cells) and mouse red blood cells (B cells). In the majority of persons examined the percentage of T-lymphocytes constituted 47.3 +/- 1,6, of B--16.8 +/- 1, and of "zero" cells--33.5 +/- 3.4. There was less T- and B-lymphocytes in the blood of elderly persons (over 50 years of age) than in the young ones. It was also shown that the T-lymphocyte population forming "active" rosettes could be assessed by the number of SRBC sorbed on their surface.
