结果 (1)在 0 Gy时，每 10 0 0个双核细胞的微核量是 11.3± 2 。7，人参水提取物≥ 5 0 0μg· ml- 1 时微核量下降，但微核量和人参水提取物的浓度之间的差异是显著的。

Results: a In the negative control group, spontaneous chromosome aberration and micronucleus rated the mice's were very low; in the positive control group, chromosome aberration and micronucleus rate of the mice's were highest. b Before cyclophosphamide intoxation, when the four kinds of vegetables and hilts juice were preventively irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate in the negative control group were lower than these in the positive control group (P.05); but after intoxation, when the four kinds of vegetables and fruits juice were therapeutically irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate were similar with the result above mentioned . c Acing the four kinds of vegetables and fruits, sea-buckthorn lad the best preventive and curative effects.

结果：a在阴性对照组中，小鼠自发的染色体畸变率和微核率极低；在阳性对照组中，小鼠染色体畸变率和微核率最高。b在环磷酰胺染毒之前，分别将4种蔬菜水果汁给小鼠进行预防性灌胃，其染色体畸变率和微核率均比阳性对照组低(P.05)；在染毒之后，分别将4种蔬菜水果给小鼠治疗性灌胃，其结果与上述实验结果相似。c在4种蔬菜水果中，以沙棘的预防和治疗效果为最好。

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。
