(14) In this study, thymic rosettes (TR), which are cell-cell complexes of thymic lymphocytes and stromal cells, were isolated from human thymic tissue, and were characterized.
(15) Incubation of normal pig lymphocytes in serum samples collected from 10 sows immediately before, and at daily intervals after mating with a vasectomized boar significantly elevated the rosette inhibition titre (RIT) of a standard antilymphocyte serum in 6 animals on the first but not on the 2nd and 3rd day after copulation.
(16) Histamine in vitro also inhibited the E-rosette formation, but only in patients with allergic disorders.
(17) Fragments of human erythrocytes inhibited E rosette formation by intact human red cells, but did not result in a significant decrease in rosette formation by intact guinea pig erythrocytes; likewise, guinea pig fragments had no inhibitory effect on rosette formation by human erythrocytes, demonstrating that separate receptors were required for the two red cell types.
(18) With sheep RBC, lymphocytes from 2 of the 5 rabbits studied formed rosettes to the extent of 1.5% in the system containing glutaraldehyde.
(19) Taking the percentage of zymosan-complement complex rosette forming cells (ZC-RFC%) and the number of zymosan-complement Complex rosette forming cells (ZC-RFC) in the peripheral blood as indices of humoral immunity, bone marrow derived lymphocytes were detected by modified Sondra B cell assay in 24 healthy aged taking part in Taichiquan (88 style) exercise and 24 age-matched normal subjects without any physical training.
