METHODS:The micronucleus test of Vicia faba root tip cell was used to detect the water quality,and to survey the chemical oxygen demand.The micronuclear rates and Pollution Index were determined and the F-test was used to evaluate the difference in micronuclear rates among different samples.

材料与方法：用蚕豆根尖细胞微核技术对各采样点水样进行监测，并对各水样进行化学需氧量(chemical oxygen demand，CODcr)的测定，统计分析各采样点水样的蚕豆根尖细胞微核千分率及污染指数。

Micronucleus test results exhibited that significant differences in micronuclear rates were determined between 0.4 mL bone cement and 0.4 mL microsphere-coated bone cement groups and negative control group, but no significant difference was detected among other groups. This revealed that this microsphere-coated bone cement leaching liquor did not show significant cell heredity toxic effects. Nevertheless, microsphere-coated bone cement in the high concentration and high dosage groups exhibited low toxic effects, mainly showing increased hemolysis rate and micronuclear rate. Thus, it was necessary to control the dosage and concentration of microsphere-coated bone cement.

微核实验结果显示除0.4 mL骨水泥组和0.4 mL微球骨水泥组的微核率与阴性对照组差异有显著性意义，其余各组差异无显著性意义，说明该微球骨水泥的浸提液无明显细胞遗传毒性作用，但是高浓度和高剂量组的微球骨水泥仍有较低的毒性作用，主要表现为溶血率和微核率的提高，因此在应用时要适当控制微球骨水泥的剂量和浓度。
