摘要: 为研究A - CM 海洋生物制剂的抗突作用,进行了抗细菌回复突变试验,抗微核效应试验和抗DNA 氧化损伤试验。结果表明:在未加S9 条件下,A - CM 制剂可抑制叠氮钠诱发的组氨酸缺陷型鼠伤寒沙门氏菌TA100 菌株突变。A - CM 喂养小鼠,可抑制随饲料摄入的诱变剂Cd2 + 和NO-2 引发的骨髓嗜多染红细胞微核。体外试验可有效防护H2O2 对人血白细胞DNA 的氧化损伤。提示A - CM 制剂对某些毒物诱发的DNA 和染色体水平的突变均有一定抵抗作用。

Abstract: The antimutagenicity of A - CM marine biological preperation was studied with several genotoxicological test s which included antigenetic reverse mutation test in S almonella typhimurium st rain TA 100 , the test of antimicronucleus effect in vivo mice bone marrow on PCEs induced by common mutagens Cd2 + and NO -2 ,and DNA damage resistance test . Result s consistently demonst rate that A - CM preperation has significant antimutagenic effect on gene mutation and chromosome clastogen in all above tests.

Key words: Antimutagenicity, DNA damage, Marine biological preperation
