摘要: 目的 采用细菌回复突变试验(Ames试验)、CHL细胞染色体畸变实验和小鼠骨髓细胞微核试验,综合评价血栓通注射液的遗传毒性。方法 Ames试验,在有或无S9活化条件下,血栓通注射液设置128.0、320.0、800.0、2 000.0、5 000.0 mg每皿共5个浓度组,用平皿掺入法检测菌株TA1535、TA97、TA98、TA100和TA102的致突变性。CHL细胞染色体畸变试验,血栓通注射液设置125、250、500 μg·mL-1共3个浓度组,分别对CHL细胞染毒4 h(在有或无S9活化条件下)和24 h(在无S9活化条件下)。油镜下观察300个中期分裂相细胞中含结构畸变和数目畸变的细胞数。小鼠骨髓细胞微核试验,血栓通注射液设置104.3、208.6、417.2 mg·kg-1共3个剂量组。KM小鼠经尾静脉注射给药2 d,末次给药后24 h取材,计数嗜多染红细胞(PCE)中的微核数和PCE比例。结果 血栓通注射液各处理组测试菌株回复突变菌落数与溶媒对照组相比均未见增加1倍以上。血栓通注射液各处理组的结构畸变率和数目畸变率与溶媒对照组比较均无明显差异(P>0.05)。各剂量组小鼠骨髓细胞平均含微核嗜多染红细胞率与溶媒对照组比较均无明显差异(P>0.05)。结论 本实验室确定的条件下,血栓通注射液的遗传毒性评价结果为阴性。

Abstract: Objective Ames test, Chromosome aberration test and mouse bone marrow micronucleus test were used to evaluate the genotoxicity risk of xueshuantong injection. Methods Ames test, Five strains of bacteria including TA97, TA98, TA100, TA102 and TA1535 were exposed to xueshuantong injection at concentrations of 128.0, 320.0, 800.0, 2 000.0 and 5 000.0 μg/plate by plate incorporation ,with and without S9 respectively. Chromosome aberration test, CHL cells were exposed to xueshuantong injection for 4 h (with and without S9) or 24 h (without S9) at concentrations of 125, 250 and 500 μg·mL-1. The number of cells with structural and numerical aberrations in 300 metaphase cells in each group was counted under oil lens. Mouse bone marrow micronucleus test, KM mice were dosed with 104.3 , 208.6 and 417.2 mg·kg-1 by intravenous injection of xueshuantong injection for two days, and the bone marrow samples were collected at 24 h after the last treatment.The number of immature erythrocytes per animal were scored , and the proportion of immature among total erythrocytes was determined for each animal by counting erythrocytes for bone marrow. Results Compared with the concurrent solvent control, the mean number of revertant colonies in each group increased less than once. Compared with the concurrent solvent control, there was no significant difference in the rate of structural aberration and numerical aberration caused by xueshuantong injection (P>0.05). At 24 h post-administration of xueshuantong injection, there was no significant difference in the average micronucleated polychromatic erythrocyte rate in each group compared with the solvent control (P>0.05). Conclusion The genotoxicity evaluation result of xueshuantong injection is negative under the test conditions.
