[Mechanism of formation of active T-rosette forming cells in multiple sclerosis patients].

On the basis of examining active rosette-forming T-lymphocytes contained in the peripheral blood of patients with disseminated sclerosis a relationship between the changes in the percentage of lymphocytes with different number of erythrocyte adhesions and the morbid process phase was discovered. The regularity of this phenomenon has given the authors grounds to assume that the diminution of the number of active rosette-forming T-lymphocytes (with 7 and more erythrocyte adhesions) in patients with disseminated sclerosis is due to redistribution of the various lymphocyte populations in the process of the immune response. This redistribution may be due to the lymphocyte fixation in the target and the immunocompetent organs.

[Polymorphonuclear rosettes in the peripheral blood of multiple sclerosis patients].

The study is related to the distribution of rossette-forming cells--lymphocytic and polymorphonuclear leukocytic--lymphocytes and polymorphonuclear leukocytes (neutrophils) in the peripheral blood of patients with disseminated sclerosis. An increase of the polymorphonuclear leukocytes and polymorphonuclear leukocytic content was found in the exacerbation period. Similar data were obtained in the process of reproduction of chronic experimental allergic encephalitis in maccaca rhesus.
