用原子吸收光度法测定了外阴白斑病患者外阴毛中锌、铜、铁、锰、镉５ 种微量元素含量，结果显示：外阴白斑病患者中锌含量明显高于健康对照组（ Ｐ＜ ００５）；而铜、铁、锰、镉含量无明显变化（ Ｐ＞００５）。
The content of zinc, copper, iron, manganese and cadmium in vulvar leukoplakia were measured by atomic absorption spectrophotometry. The results showed that the content of zinc in vulvar leukoplakia was significantly higher than that in healthy control (P <0 05), while the content of copper, iron, manganese and cadmium had no significant change (P> 005).
