Abstract: The genotoxicity and antimutagennic effect s of placental immunoregulatioan on polypeptide (PIP) against mutagen2induced chromosomal aberrations and micronuclus formation in human lymphocytes in vit ro and bone marrow of mice were studied. PIP(0. 02 and 0. 03ml/ ml) significantly inhibited spontaneous andγ rays 2induced micronucleus formation and MMC2induced chromosomal aberrations in vit ro. Mentimes PIP(0. 02 and 0. 03ml/ ml) st rongly suppressed also micronucleus formation induced by CP in PCEs of mice. PIP has no genotoxicity and has antimutagenic effect s.

Key words: placental immunoregulation polypeptide, antamutagenic effect s, genotoxicity, chromosome aberration, micronucleus.
