Abstract］ Objective To observe the clinical effect of treatment of endemic arsenism with organic selenium preparation.

摘要］ 目的观察有机硒制剂治疗地方性砷中毒临床效果。

The peripheral blood mononuclear cells were aseptically isolated from goats not treated by selenium and cultured in vitro in media containing sodium selenite respectively at the levels of 4,8,12 and 16 μg/mL, and then their in vitro activation and IL-2 levels were tested.

无菌分离未服硒山羊PBMC，分别加入4，8，12和16μg/mL亚硒酸钠进行体外培养，检测硒在体外对PBMC的活化作用及其分泌IL-2的影响。

The expression of Bcl-2 was weak or negative; there is no difference among various groups.Research Conclusion: lCadmium can accelerate the apoptosis of GCs and is related with dose; 2Cadmium accelerate atresic of follicular; and increase the number of interstitial gland;3Cadmium enhance the expression of bax, and no affect obviously on bcl-2;4 Selenium restrained the effect of cadmium-induced apoptosis on granulosa cells, but it cant be interdicted completely.

实验结论：1 镉能促进小鼠卵巢颗粒细胞凋亡，并具有剂量效应关系。2 镉能促进卵泡闭锁，使卵巢间质腺数量增加。3 镉能增强颗粒细胞凋亡相关基因bax的表达，对bcl-2的表达则无明显影响。4 硒具有一定的抑制镉致颗粒细胞凋亡的作用，但不能完全阻断。

Selenium is an important biosis element,and its content in environment directly affects the health and safety of human beings,animals and plants.

1引言硒是生态环境中一个重要的微量元素，其丰缺与人和动植物的健康有着密切关系。

Using phalloidium staining we observed a sharp disappearance of the actin stress fibers, formation of extensive microvilli as demonstrated by the scanning microscopy and formation of typical bile canaliculi structures as confirmed by a monoclonal antibody to aminopeptidase N which is a BC specific antigen. The appearance of microvilli and BC suggested that selenium is able to elicit a differentiation reprogramming.

利用Rhodamine pholloidin 染细胞内的F-actin 显示出细胞内的stress fiber 大部分都消失；利用Scanning electron microscope可以检测到细胞表面有明显的microvilli 的结构；并且利用标定胆小管的特殊蛋白可以发现硒元素可以诱导HuH7 肝癌细胞分化产生胆小管的结构。

The cheap and easily available nonmetal selenium catalyst possesses both efficiency to catalytically activate carbon monoxide and the function of phase-transfer catalysis. What is more, it can be recycled.

价廉易得的非金属硒作催化剂不但具有良好的催化活化CO的性能及反应过程相转移催化特性，而且能循环使用。

So, recycle techniques by circulative reuse of selenium drums become efficiency approach to reduce environment pollution and debase print cost.

于是，通过循环再利用硒鼓的再生利用技术便成为减少环境污染和降低打印成本的有效途径。

Additional, certain microelement, the intake that is like chromic, manganese, zinc, vanadium, Selenium decreases and lead, cadmium, cobaltic intake increases, contract this disease easily also.

另外，某些微量元素，如铬、锰、锌、钒、硒的摄入量减少和铅、镉、钴的摄入量增加，也易患此病。

The content of selenium in the edible fungi including Pleurotus ostreatus,Agaricus bisporus,Lentinus edodes,Plrurotus cornucopiae and Flammulina velutipes is determined by ultraviolet spectrophotometry method.

以硫酸-高氯酸作为消化剂，邻苯二胺替代3，3-二氨基联苯胺，在硒含量为6~30μg范围内对平菇所做的重复性实验和回收率实验都有较好的效果。

And eating the cruciferous vegetables with a selenium source is 13 times more potent than the vegetable alone.

将这些十字花科与富含硒的蔬菜一起烹调效果将超过单独烹调的效果的13倍。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
