We have studied influence of polyoxipropilenpolyole Laprol-504-2-100 on the state of immunobiological reactivity of animals. Intensive depression of oxidation-reduction processes and tissue hypoxia, inhibition of bactericidal action of skin were proved under influence of 1/10 and 1/100 DL50. Studied xenobiotics, reduce level of bioenergetic homeostasis. Laprol-504 causes strong action on state of immunobiological reactivity. Decrease of percentage content of expressive Е1-, Fс-, С3-receptors of lymphocytes was proved. Decrease of antibody forming, antigenconnecting, hemolysinproducing abilities of immunocompetent cells was obtained.
