[Studies on the number of rosette forming lymphocytes in the day-longitudinal testing (author's transl)]

The number of rosette forming lymphocytes with sheep and mouse red blood cells was examined in healthy persons. 1. On average 51 +/- 4,9% T- and 10 +/- 2,1% B-lymphocytes were found at 7 a.m. (n = 25). 2. There was no proof of influences upon this percentage rate during the various time of the day.
