[Immunomodulating effect of cyclophosphane under different modes of administration to mice]

A study was made of the effect of injection of cyclophosphamide (CP) immunomodulating to BALB/c mice, according to 3 schemes of injection with the whole dose being 200 mg/kg. In all, the state of peripheral blood and spleen, the cellular content of lymph nodes and the number of DNA-synthesizing cells in them were studied, in addition to the ability of lymph node lymphocytes to proliferative reaction on T and B cells mitogens in vivo. It was determined that a 2-fold injection of CP, in contrast to 10- and 5-fold injections, resulted in splenomegaly and leukocytosis in the experimental animals. By means of quantitative tests in vivo, in was demonstrated that the dynamics of restoration of proliferative responses to mitogens depends on the CP injection scheme. These tests proved to be more informative for registration of immunomodulating effect of CP, than the study of cellular content of lymph nodes and the number of DNA-synthesizing cells in them.
