目的本文旨在研究改性大豆植物油的遗传毒性。方法通过Ames试验、骨髓细胞微核试验、精子畸形试验,评价改性大豆植物油是否具有遗传毒性。结果 Ames实验结果表明,改性大豆植物油对TA97、TA98、TA100、TA1024株试验菌株结果均为阴性;小鼠骨髓细胞微核试验中各剂量组2种性别小鼠骨髓嗜多染红细胞与成熟红细胞的比值为1.33~1.47,未见样品对2种性别小鼠的骨髓细胞有明显的抑制作用,各剂量组2种性别小鼠骨髓嗜多染红细胞微核率与样品溶剂对照组比较,差异均无统计学意义(P<0.05);小鼠精子畸形试验中各剂量组小鼠精子畸形率与样品溶剂对照组比较差异无统计学意义(P<0.05)。结论三项致突变试验结果均为阴性,未见改性大豆植物油具有遗传毒性。
Purpose This paper aims to study the genotoxicity of modified soybean oil. Methods Ames test, bone marrow micronucleus test, sperm abnormality test to evaluate whether the modified soybean oil is genotoxic. Results The results of Ames test showed that the modified soybean oil was negative for TA97, TA98, TA100 and TA1024 strains. In the bone marrow micronucleus test, the bone marrow polychromatic erythrocytes and mature erythrocytes The ratio of 1.33 to 1.47, no sample of two sexes of mice bone marrow cells were significantly inhibited, the two groups of mice of each dose group of micronucleus rate of bone marrow polychromatic erythrocytes compared with the sample solvent control group, the difference was There was no significant difference (P <0.05) between the sperm deformity rate and the solvent control group in the mice sperm abnormality test (P <0.05). Conclusion The results of the three mutagenic tests were negative, no modified soybean oil has genotoxicity.
