用LSAB免疫组化法，检测了54例声门上型鳞状细胞癌手术切除标本E-cd和EGFR的表达。

Results showed that application of EDTA to the soil significantly increased the concentration of Cd in the leaves of Pctunia hybrida, Tagetes erecta L and Solenlstemon scutellarioides and those of Pb in the leaves of all flowers.

结果表明；施加EDTA溶液(3mmol/kg)7d后，矮牵牛、万寿菊、彩叶草叶部Cd含量显著增加(P.05)；所选4种花卉叶部Pb的含量均极显著增高(p01)。

The enrichment coefficient and translocation factor both reached 1 of Tagetes erecta L with Cd and Tagetes patula with Pb, which indicated that Tagetes erecta L and Tagetes patula could be used for the remediation of contaminated soil.

施加EDTA后万寿菊对Cd和孔雀草对Pb的富集系数和转移系数均达到了1以上，这表明这两种植物可用于螯合辅助植物提取方式的污染土壤修复。
