摘要: 本文应用体外培养人淋色细胞并进行微核、染色体畸变的检测以及小鼠骨髓微核实验的研究,评价胎盘免疫调节肽(Placetal immunoregulating polypeptide ,PIP) 遗传毒性和抗突变效应,实验结果表明:胎盘免疫调节肽(0102 和0103ml/ ml) 可显著抑制培养人淋巴细胞的自发和γ射线诱发的微核形成以及丝裂霉素C(MMC) 诱发的染色体畸变,并能明显抑制环磷酰胺诱发的小鼠骨髓多染性红细胞微核的增加,揭示了胎盘免疫调节肽具有抗突变作用。

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.
