摘要: 目的: 观察可降解聚乙醇酸(polyglycolic acid, PGA) 生物支架材料是否具有引起基因突变的潜能。方法:采用Ames试验和小鼠淋巴瘤试验评价PGA浸提液的遗传毒性。结果:在Ames试验中,与阴性对照组比较,可降解PGA的浸提液均未引起4个试验菌株出现显著的回变菌落数改变 (P>0.5)。在小鼠淋巴瘤试验中,可降解PGA各个剂量浸提液组的克隆形成率较阴性对照组均无明显差异 (P>0.5), 且显著小于阳性对照的克隆形成率 (P<0.5)。结论:可降解PGA纤维材料浸提液对于Ames试验菌株,小鼠淋巴瘤细胞无基因诱变性。

Abstract: OBJECTIVE: To investigate the genetic toxicity of bio-degradable polyglycolic acid (PGA) fiber materials and to assess its safety. METHODS:The bacterial reverse mutation study (Ames test) and the mouse lymphoma assay ( MLA) were used to test the potential genotoxicity. RESULTS: In Ames test,the bio-degradable PGA fiber material extract did not increase the revertant colonies (P>0.5). From the mouse lymphoma assay,there was no significant difference of the clone forming rate between the PGA fiber extract group and the negative control group (P>0.5),however there was a significant difference between the PGA group and positive control group(P<0.05). CONCLUSION:The bio-degradable PGA fiber material was not mutagenic as tested by Ames and mouse lymphoma assay.

Key words: bio-degradable PGA fiber material, Ames test, mouse lymphoma assay
