[ENGAGEMENT OF SEROTONIN-MODULATING ANTICONSOLIDATION PROTEIN IN REGULATION OF EMBRYOGENESIS OF LYMNEAE STAGNALIS AND LEWIS SARCOMA IN HYBRID MICE Fl C57B2/6 X DBA].

The article concerns study of the effects of a novel serotonin-modulating anticonsolidation protein (SMAP) being in a linear relationship with serotonin level, on embryogenesis of Lymneae stagnalis and Lewis sarcoma in hybrid mice Fl C57B2/6 X DBA. Inhibition of embryogenesis of Lymneae stagnalis on the stage of four blastomers and late blastula, lack of changes on the stage of trochofora and acceleration of metamorphosis under the effects of SMAP in a dose-dependent manner was observed. Short-term retardation (during the first 10 days) of development of Lewis sarcoma in mice and survival of 25% of transferring animals under high doses of SMAP was revealed.
