This paper researched cabbage of Cruciferae colewort by planting cabbage in soils which were polluted by cadmium of different concentration. We analyzed poison of cabbage which was polluted by cadmiums in different concentration by using OCT machine system to measure cabbage lamina and observing physical change of fabric of cabbage, and confirmed the characteristic of Cadmium circulation of supergenic geochemistry accordingly.

本文主要以十字花科芸苔属植物甘蓝为研究对象，通过在不同浓度的受镉离子污染的土壤中进行种植，观察甘蓝组织结构物理表征变化，并应用光学相干层析成像系统（Optical Coherence Tomography，OCT）对甘蓝叶片组织样本检测其变化情况，从而分析得出不同镉离子浓度对甘蓝的累积毒害作用以及镉的表生地球化学循环特点。

为了解铜、镉对泡泡草根、茎、叶细胞亚显微结构的毒害及作用位点，以期为进一步研究鸭跖草属植物的耐重金属机理提供理论基础，本文通过透射电子显微技术研究了75 μmol·L-1铜和50μml·L-1镉及其交互污染对泡泡草根、茎、叶细胞超微结构的影响和铜、镉在细胞中的分布。

Ferrum deficiency can promote the absorption of cadmium,and zinc can antagonize the injury caused by cadmium in kidney.

缺铁能促进镉吸收，使镉进入体内的量增加；锌对镉引起的肾损伤有拮抗作用。

These results suggested that there was significant genotypical difference in rice in response to Cd toxicity.

本研究结果表明，随着镉处理水平的提高，镉对水稻幼苗的毒害作用增加，但是水稻对镉毒害的响应存在明显的基因型差异。

Objective To observe the DNA damage effect of cadmium on hominine malignant hepatocarinoma SMMC-7721 cell line,and to discuss the application of CASP software in analysis of single cell gel electrophoresis results.

镉是一种重要的环境污染物，被美国毒物和疾病注册处列为第6位危害人体健康的有毒物质。1996年，Waalkes等发现了镉的抗肿瘤作用，使镉作为细胞毒性抗癌药物成为可能〔1〕。

The results showed that the Cd contents in soil were between 0.012-0.87mg/kg in Panlian district, and 0.019-0.47 mg/kg in Salian district. There were 15%, 19% of Cd contents in soil surpassing the Ⅱgrade environment standard in Panlian and Salian district respectively.

结果表明攀莲蔬菜基地土壤镉含量在0.012~0.87mg/kg之间；撒莲蔬菜基地土壤镉含量在0.019~0.47mg/kg；攀莲蔬菜基地和撒莲蔬菜基地分别有15%和19%的土壤镉含量超过国家土壤环境质量Ⅱ级标准。

The results showed that the cadmium pollution increases the contents of total protein and globulin,and decreases the ratio of albumin to globulin.The effect of cadmium on albumin is not statistically significant.The threshold of effect of cadmium on sero proteins of Tilapia mossambica is 0 005mg/L.

试验结果表明，镉能升高血清总蛋白、球蛋白含量，降低白蛋白／球蛋白比值，但对血清白蛋白含量没有影响；镉对血清球蛋白各组分的影响有其特异性；对莫桑比克罗非鱼血清球蛋白成分产生作用的镉浓度阈值为0.005mg／L。

Spirodela polyrhiza was cultivated in Steinberg medium with different concentration of Cd(superscript 2+) for 4 days to study the toxic effect of Cd(superscript 2+) on this kind of plant.

为了研究紫萍是否可以应用于有重金属镉污染的富营养化地表水体的治理和生态修复中，以不同浓度的镉处理4d的紫萍为实验材料，研究了在短期的培养条件下镉对紫萍生长的影响。

In addition,during the investigation of cadmium different levels distribution in Typha angustifolia Linn,we find that:l as far as the accumulate ability of different organ in Typha angustifolia Linn are concerned,root sheath leaf.

此外对狭叶香蒲体内镉的化学形态分析表明根和叶中均以氯化钠提取态最高，但在根中以去离子水和乙醇提取态存在的镉含量总和大于氯化钠提取态，表明镉在根与叶的化学存在形态有所不同。
