During the primary immune response induced by the administration of sheep erythrocytes in mice, nucleolar activation was observed in macrophages, lymphocytes as well as in plasmacytes. The first maximum (4.6%) was observed on day 3 in macrophagic cells. Maximal activation of plasmoblasts (6.6%) and plasmacytes (5.9%) was observed on day the lymphoid series the first maximum in the occurrence of cells showing specific immunological activatin was as follows: large lymphocytes on day (6.5%), medium-sized lymphocytes on day 7 (6.6%) and, ultimately, small lymphocytes (6.3%) on day 8. The study verified the possibility of using nucleolar staining for estimating its functional morphology and thus following the changes of specific immunological activation during the primary immunological response.

[Kinetics and morphology of immune reactive cells in the spleen as observed using the immune adherence method. IV. Primary response as influenced by total body irradiation in various intervals following administration of antigen].

The course of immunocytoadherence was followed in the mouse spleen during the primary immune response to intraperitoneal administration of sheep red blood cells at 24 hours, 72 hours and 6 days following a total body iradiation with a dose of 450 r after antigen administration. The number of RFC becomes reduced immediately after irradiation. The reduction thereof always correlates with a relative increase of macrophages. Small and medium-sized lymphocytes rapidly disappear from the population of rosette-forming cells. If the irradiation had been carried out before the radiation-uninfluenced reaction reached its maximum, the large lymphocytes relatively increase in number. In other cases their immunocytoadherent activity also shows a steadily decreasing tendency. During the primary reaction, irradiation always increases the total relative plasma cell count as related to the other RFC. In such cases the propurtion of the mature forms is larger than of the blastic ones. The values observer at the end of the studied postirradiation period in the sourse of the primary reaction are always characterized by a higher proportion of the plasma cell line at about 20 - 25.

[Kinetics and morphology of immune reaction cells in the spleen studied using the immuno-cyto-adherence reaction. V. Secondary response and its modification by whole-body irradiation at different intervals following administration of antigen].

Observations were made of the course of secondary immunological response, using the immuno-cyto-adherence method under the influence of 450 r general body irradiation on murine spleen following secondary ram erythrocyte immunization. Irradiation was applied 24 hours, 72 hours and 6 days after an i.p. administration of antigen. Irradiation was immediately followed by an absolute as well as relative drop in RFC number and by an overall drop in splenic cell number. In case of irradiation applied prior to reaching the secondary reaction quantitative maximum, there was a development of the increment and another RFC quantitative maximum was reached between days 15--20 after irradiation. Small and medium size lymphocyte values were seen decreasing immediately after irradiation. Where irradiation took place prior to reaching the quantitative maximum of a normally proceeding anamnestic reaction, large lymphocytes constituting RFC were increasingly represented after a certain period of stagnation or even without it. Plasmatic series cells on irradiation tended to increase their total share to become a prominent cell element after delayed quantitative RFC maxima had been reached and to reach complete predominance towards the end of the period of time under observation. A relative increase in the proportion of macrophages was seen immediately after irradiation.

[Kinetics and morphology of immune reactve cells in the spleen as observed uwing the immune adherence method. III. Spontaneous immunocytoadherence as influenced by total body irradiation].

The course of spontaneous immunocytoadherence as influenced by a total body 850 r irradiation was studied in the mouse spleen. Prior to the total body irradiation 0.87 RFC/100 cells occurring spontaneously, without any previous antigenic stimulus, were dislosed in the spleen. Twenty four hours after iraadiation 0.075 RFC/1000 cells were detected. This number dropped to 0.023 RFC/1000 cells at day 4 after irradiation. A qualitative morphological analysis showed the following values: 65,1% of the spontaneous RFC were small lymphocytes, 24.5% were medium-sized lymphocytes and 3% large lymphocytes; 1.1% were plasma cells and 5.4% macrophages. Twenty four hours after irradiation with a dose of 850 r the RFC contained 9.3% plasma cells, and 90.7% macrophages, the respective numbers on day 2 being 7.5% and 98.3%. At day 4, permitting to demonstrate the RFC in significant numbers there occurred macrophages only. The model experiment has shown that the formation of spontaneous rosettes represents a cirtually normal immune reaction.
