Faba root tip was studied through detection of micronucleus technique Both of nitrate (0.08 mol/L) and nitrite (0.80 mmol/L) with low concn of could significantly induce the formation of micronucleus of V. faba root tip (P.01), and showed an obvious dose effect, i.e. the permillage of micronucleus was in linear increase with rising up of mutagen concn within a certain range.

结果］低浓度的硝酸盐(0.08mol/L)、亚硝酸盐(0.80mmol/L)均能显著诱发蚕豆根尖微核的形成(P.01)，并呈现出明显的剂量效应，即微核千分率在一定范围内随诱变剂浓度的增加而线性增加。

Results Frequency of micronucleus in human blood lymphocytes increased significantly by treatment with yttrium chloride and praseodymium chloride, and it increased with the concentration of the both agents, to a certain range.

结果 钇和镨能够引起人血淋巴细胞微核率显著升高，在一定范围内，微核率随氯化钇、氯化镨处理浓度的增大而提高。

Nano-Fe_3O_4 can induce DNA single-strand breaks without significancy and can not induce micronuclei formation and percentage of apoptosis. Nano-Fe_3O_4 can aggravate the effect of CdCl2 on DNA single-strand breaks and chromosome damage in HepG2 cells. They showed synergistic effects on DNA single-strand breaks after the data were statistic analyzed.

结果发现CdCl2能引起DNA断裂损伤、微核率的增加和细胞凋亡率的增加；nano-Fe_3O_4能引起DNA断裂损伤增加，但无显著意义，未引起微核率和细胞凋亡率的增加；nano-Fe_3O_4能加重CdCl2的对细胞DNA断裂损伤和染色体损伤，且二者联合作用对DNA断裂损伤的结果经统计分析认为有协同作用。

Eamamined by fluorescin staining and Giemsa staining, 0.2 mg/L colcemid was considered suitable for inducing high percentage of micronuclei in A9 (neo12) cells, without causing death of a mass of cells.

通过荧光染色和吉姆萨染色分析，结果表明，A9(neo12)细胞经0.2 mg/L秋水仙素酰胺处理48 h后，89﹪的细胞产生微核化，每个细胞平均形成10个微核。

RESULTS: There was significant difference in micronuclear rates of every site(P.01). PI values of 7 among 9 sampling sites were over 2.00. The micronuclear rates were higher in the sites with higher PI.

结果： 各采样点水样的蚕豆根尖细胞微核率均高于对照组(P.01)，9个采样点中有7个采样点的污染指数在2以上，污染指数高的水样组细胞微核率也高。

The experimental results show:(1) The water in South Fei River has been comtaminated, especially in industrial and residential part.(2)Vicia faba(QI_1) is sensitive to mutagen, and liner relation between the freguency of micronuclear cell in the root tip cells of Vicia faba(QI_1)and concentration ...

结果表明，南淝河水体已被污染，尤其以工业区和居民生活区污染严重；启豆Ⅰ号对诱变物反应敏感，水环境中污染物浓度与微核千分率呈线性相关，因此启豆Ⅰ号作为微核监测技术的实验材料是可靠的。

Mitotic index increased in some certain low concentration and decreased in high concentration of heavy metal ions.

在一定浓度范围内，微核率随重金属浓度的升高而增加，达到一定浓度后，微核率反而有下降的趋势。
