title: [Effect of T-activin on peripheral immunity organs in intact and thymectomized mice].
abstract: Morphometry of the spleen, axillary lymph nodes and cytological assay of the bone marrow and peripheral blood were performed in (CBA X C57BL)F1 mice 1, 5, 10 and 15 days after subcutaneous injection of 0.5 microgram T-activin to intact and thymectomized (when adult) mice 2 months after operation. It was demonstrated that in intact animals, injection of T-activin stimulated the whole system of immunogenesis. The time course of plasmatization and the response of the germinative centers differing from that seen during antigen administration suggests that T-activin is not immunogenous, acting as a stimulant of the previous immune responses. The permanent amount of the degenerating cells attests to the lack of the toxic drug effect.
