Sheep erythrocyte (E) rosette tests were performed with E from 3 different sheep. The E rosette test for "active" T lymphocytes was performed with untreated E. E tests for the quantitation of the total number of T lymphocytes were performed with untreated as well as AET-treated E, in assays with and without fetal calf serum (FCS). Lymphocytes from patients with active and stable multiple sclerosis (MS) and with infectious mononucleosis (IM) as well as from healthy individuals were examined. The "total" E test performed with untreated E from one sheep and lymphocytes from patients with active MS gave lower percentages of rosette-forming cells (RFC) than when E from the other two sheep were used. FCS in the medium, or AET treatment of E partly but not wholly abrogated this difference. The origin of the E is thus of importance for the results of the rosette tests in patients with active MS, even if FCS or AET treatment is used.

Sequential immunologic, cytochemical, and cytokinetic studies were done on single lymphoid cells in the peripheral blood of 6 children with infectious mononucleosis (IM) and 1 child with toxoplasmosis 1-2 wk after onset of symptomatology. The absolute number of AET-SRBC rosetting (E+) cells was increased in all patients; the absolute number of cells with surface IgM (slgM+) was increased in 3 of 7 patients. On the average, 46% of all lymphoid cells were E+la+slgM-, 35% E+la-slgM-, and 5% E-la+slgM+. Of the E+la+slgM- cells, only 7% were shown to have a dot-like esterase reaction pattern. Of the E+la-slgM-cells, 17% were esterase positive. The mean labeling index of the former was 18.2%, the mean labeling index of the latter 4.4%. No proliferating slgM+ cells were observed in the 6 children with IM. The esterase reactions and the labeling indices of suppressor-cytotoxic and inducer-helper T cells were similar to those of E+la+slgM- and E+la-slgM- cells, respectively. These results suggest that the vast majority of the atypical cells in IM corresponds to activated suppressor cells, while a minority appears to be proliferating helper cells.
