1、2014-11-15家蚕茧壳水解粉的急性毒性和遗传毒性1*吕群,宁文艳,王智,王玉霞,顾响响,武鹏凯,林峰,王春梅(北京中医药大学中药学院生物制药系,北京100102)摘要:目的研究家蚕茧壳水解粉的急性毒性和遗传毒性,为其进一步开发利用提供安全依据。方法应用小鼠急性毒性试验、体外哺乳类细胞(V79/HGPRT)基因突变试验、小鼠骨髓细胞染色体畸变试验及小鼠精子畸变试验对家蚕茧壳水解粉毒性进行试验观察。结果该家蚕茧壳水解粉对雌雄小鼠LD50均大于11.50g/kg,属实际无毒物质;基因突变试验中各受试物剂量组的突变率均没有达到自发突变率的3倍,亦无
2、剂量-反应关系,结果为阴性;染色体畸变试验中家蚕茧壳水解粉各剂量组与阴性对照组无显著差异(P>0.05),精子畸变试验中,样品低、中剂量组与阴性对照组无显著差异(P>0.05),而高剂量组畸变率显著低于阴性对照组(P<0.05),证明试验结果均为阴性。结论本次试验条件下,该家蚕茧壳水解粉属实际无毒级,未显示有急性毒性和遗传毒性作用。关键词:家蚕茧壳水解粉;小鼠;急性毒性;遗传毒性中图分类号:R994.4文献标志码:AExperimentalstudiesontheacutetoxicityandgenetictoxicityofsilkwormc
