Results We have got the result by tracing observation to 15 patients of arsenic poisoning:that there are more than 15 years from hyperkeratosis of skin caused by arsenic poisoning to cancer,average 17.5 years.

结果 通过15例砷中毒患者的追踪观察得出：砷中毒病人皮肤角化到癌变的间变期初步认为在15年以上，平均为17.5年，角化部位的外伤不易愈合，且易发生感染，是加速癌变的诱因，并分析了手、足皮肤角化点癌变发生率高的各种因素。

He activity of y-GT also had dose- dependent and time-dependent effect and became lowest on day 7 at the concentration of 0.5 and 1.0 umol/L. The activity of TAT increased. On day 4, the cells treated with 0.25, 0.5 and 1.0 umol/L of As2O3 had higher activity compared with control group (P.05) and it continued afterwhile.

AT随着各给药组时间的延长而上升，并随给药剂量增大而上升程度更大，培养第4天，0.25 μmol／L浓度的亚砷酸组TAT的比活性较对照组高(P＜0.05)，0.5 μmol／L、1 μmol／L浓度的亚砷酸组TAT的比活性较对照组更高(P＜0.01)，以后各天给药组均高于对照组(P＜0.01)。

Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).

简单的说，先用切刀制成100um的冠状脑切片，然后用含有4%戊二醛在0.1 mmol/L的二甲砷酸缓冲液(PH7.4)中固定1小时后，放在含有1%四氧化锇的0.1 mmol/L的二甲砷酸缓冲液中2小时，接着用蒸馏水冲洗后，放在1%的aqueous uranyl acetate中过夜，接下来用梯度酒精(至100%)脱水，然后用丙酮干燥，再用Durcupan ACM包埋，切成0.1um的超薄切片后用3%的lead citrate染色，随后用透射电子显微镜观察。

This anion pump is composed of two subunits, the catalytic 63KDa ArsA, a hydrophilic protein, when purified, exhibits oxyanion-stimulated ATPase activity, the hydrophobic 45. 5KDa ArsB protein, located in the inner membrane of E. coli, is the putative anion translocating channel and also serves as the anchor for ArsA to attach on the membrane.

ArsATP酶由水溶性的63KDa的ArsA蛋白和膜整合的46KDa的ArsB蛋白组成，ArsA蛋白是催化亚基，具有亚砷酸盐和亚锑酸盐激活的ATP酶活性，ArsB蛋白则构成转运亚砷酸盐和亚锑酸盐的阴离子通道，同时作为ArsA蛋白在膜上的结合位点。

People have paid attention to the pollution of soil and water quality caused by using organic arsenic chemistry reagent to prevent and cure apple-tree canker in our apple area, so it has an important purpose to seek a harm-free way for sustaining development of apple. The tests studied the effect of prevention and cure on apple-tree canker with EM mud, EM liquid, 40%'Fumeishen powder' and contrast. The results showed that the EM mud was superior to the EM liquid, 40% 'Fumeishen powder' and contrast. The prevention and cure effects of EM in 2006 and 2007 were 92.7% and 93.5%, while the recurrence rates of canker scars 1.8% and 2.8% respectively. And the healing effect of scar is 50.4%. So, it was considered as a new way to prevent and cure apple-tree canker with EM mud.

中国各苹果主产区果农长期使用有机砷等化学制剂防治腐烂病，对土壤、水质等环境造成的污染已引起人们的关注，寻求无公害的方法防治腐烂病，对苹果业可持续发展具有重要意义；本试验设EM活性菌泥涂抹、EM活性菌液涂抹、40%福美砷可湿性粉剂50倍液刮涂和对照（只刮除腐烂病疤，不涂药）4个处理，三次重复，进行了苹果树腐烂病的防治研究；结果表明，EM活性菌泥在防治效果、病疤复发率和促进病疤愈合效果方面均优于其它处理，其当年和第二年4月的防治效果分别为92.7%、93.5%，病疤复发率分别为1.8%、2.8%，促进病疤愈合效果也最好（50.4%）；因此，作者提出，将EM活性菌融入粘泥载体中制成菌泥，涂抹在腐烂病疤上，以菌治菌，是防治苹果树腐烂病的新途径。

As our experiments were concerned, the after growth of InGaP, GaAs was grown at a lower temperature than that for InGaP. This made the P atoms on the InGaP surface hard to desorb and greatly reduce the thickness of InGaAsP intermixing layer.

在我们的实验中，成长完磷化铟镓后，以较低的温度成长砷化镓，这将使磷化铟镓表面的磷原子较不易脱附，因此可显著的减少磷砷化铟镓四元混合层的厚度。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
