Under certain conditions, the activation and migration of soil Cd were accelerated by the interaction of Pb and Cd and increased Cd uptake by wetland rice. The organic-bound Cd in rizhosphere decreased by 90%. These phenomena illustrates that the interaction is very important for the transformation of soil Cd fractions. Meanwhile, the interaction distinctly affected the composition of roots secretion and their coordination abilities with heavy metals, causing clear variation to Cd amount in root cortex and middle columniation.

在一定的实验条件下，Pb和Cd的交互作用促进了Cd的活化与迁移，增加了水稻地上部分对Cd的吸收，使根际土有机结合态Cd下降了90%左右，表明交互作用对Cd形态的转化是一个重要的控制因素；同时交互作用对根系分泌物的组成及其与重金属的配位能力有着明显的影响，使Pb、Cd在根系皮层和中柱中Cd的含量有明显变化。

Analysis indicated that the ratios of the Cd forms extracted by ethanol and by deionized water in root, and the ratios of soluble Cd in root cell showed accordancy with the ratio of Cd transported from root to aboveground parts, and also the ratios of the Cd forms extracted by ethanol and by deionized water in stem, and the ratios of soluble Cd in stem cell showed accordancy with the ratio of Cd translocated from rice straw to grain.

分析表明，两供试品种根组织中乙醇提取态和去离子水提取态Cd的比例及根细胞中可溶性Cd的比例与根系吸收的Cd向地上部的分配比例存在一致性；茎组织中乙醇提取态和去离子水提取态Cd的比例及茎细胞中可溶性Cd的比例与植株地上部积累的Cd向籽粒分配的比例间存在一致性。

The features of AAA adsorbed on the ethylatedβ-CD polymer were similar with those of the parentalβ-CD polymer, but theadsorption ratios of AAA on the ethylatedβ-CD polymer were higher than those of the parentalβ-CD polymer. It may be due to the strengthened hydrophobic interactions between AAA and the ethylatedβ-CD polymer, which was caused by the ethylation of the parentalβ-CD polymer.

研究表明其对芳香氨基酸的吸附规律与母体β-环糊精聚合物类似；与母体β-环糊精聚合物相比，芳香氨基酸在该聚合物上的吸附率有所增加，这可能是因为乙基化增强了β-环糊精空腔外沿的疏水性，从而增强了乙基化β-环糊精聚合物与芳香氨基酸之间的疏水相互作用。

Based on these results and inferred to related reports from other labratories, it was possible to make some analyses and conclusions or inferrences:(1) CD〓AK with tumoricidal activity were induced and expanded in number througth costimulation of PBMC with anti-CD〓 McAb . and r IL-2 ;(2) CD〓AK induced and expanded in such manner did exibit more potent proliferation·ability and cytotoxicity which maintained for lonser time than those of LAK cells, thus CD〓AK was a new variety of antitumor effector cells worth to be explored;(3) CD〓AK could mediate MHC nonrestricted cytotoxicity and kill tumor target cells through inducing necrosis and apoptosis;(4) Normal mature lymphocytes of PBMC could be induced to proliferate and /or to die from apoptosis when they were costimulated by anti-CD〓McAb and rIL-2. Both proliferation and apoptosis were existing in the same cultivation system sugsesting that the presence of rIL- 2 might provide some accessary signals for apoptosis.

以这些结果为基础并参考其它有关文献可能做出如下分析与结论或推论：(1)用抗CD〓单抗和rIL-2共刺激外周血单个核细胞能诱生扩增出具有杀瘤活性的CD〓AK细胞，(2)与LAK相比，用这种方法诱生扩增的CD〓AK增殖能力强、细胞毒活性强而且维持时间长；CD〓AK是一类值得开发的抗瘤效应细胞；(3)CD〓AK能够介导MHC非限制性细胞毒活性，可以通过诱导靶细胞坏死和/或凋亡杀伤肿瘤细胞；(4)正常外周血单个核细胞中的成熟淋巴细胞在受到抗CD〓单抗和rIL-2共同刺激后既可诱导增殖也可诱导凋亡，两者并存于同一体系，推测rIL-2的存在可能为细胞凋亡提供一些辅助信号。

Cd inhibited the absorption of Mg and Mn in roots. However, Cd could stimulate the absorption of Fe in roots. Moreover, Cd inhibited the absorption and utilization Mg, Mn and Fe in leaves. 4. Cd inhibited the photosynthesis of Populus clones. Cd showed no significant inhibition to net photosynthesis rate, stomal conductivity and transpiration rate versus the control, under 10μM Cd treatment.

Cd胁迫还对杨树光合作用产生影响，低浓度Cd对杨树光合速率无影响，中高浓度Cd对杨树净光合速率、气孔导度和蒸腾速率等具有抑制作用，而且随着处理时间的延长和Cd胁迫浓度的提高而逐渐加大。

Burner frequently wrong, as follows:(1) are simulated burn suddenly pop-up "analog recording," failed;(2) analog recording through to disk when writing a sudden pop-up "burn failed"(Unfortunately, I lost the CD this way);(3) obviously put a CD in a blank CD, went so far as to burn prompted "Please insert a blank CD-ROM", and then withdraw from the CD-ROM.

刻录机频频出错，表现为：（1）正在进行模拟刻录时突然弹出"模拟刻录"失败；（2）模拟刻录通过，可正在写盘时突然弹出"刻录失败"（可惜我的光盘就这样损失了）；（3）明明光驱里放了一张空白光盘，刻录时居然提示"请插入空白光盘"，然后将光盘退出。

Cd〓 (1, 10, 100, 1000μM) stimulated directly GtH secretion from pituitary of common carp in vitro, with the highest GtH secretion at 100μM, GtH secretion stimulated with 1000μM Cd〓 was not higher than that stimulated with 100μM Cd〓.The antagonism between Ca〓 and Cd〓 in perfusion of the pituitary fragments was not obvious.After being preperfusion with 100μM Cd〓(with or without Ca〓), the GtH secretion of the pituitary fragment was irresponsive to 2-min pulse stmulation of 10μM sGnRH-A.

鲤鱼脑垂体碎片离体灌流孵育实验结果显示，Cd〓（1，10，100，1000μM）可直接刺激鲤鱼脑垂体分泌GtH，灌流液中Ca〓对Cd〓的拮抗作用不明显，100μM Cd〓刺激脑垂体分泌GtH达到高峰，Cd〓浓度增加到1000μM时，脑垂体分泌GtH并没有进一步增加，甚至有减少的趋势；100μM Cd〓预灌流脑垂体后，可使脑垂体对2-min 10μM sGnRH-A刺激的反应性消失；1.25mM的EDTA可消除100μM Cd〓刺激脑垂体分泌GtH的作用；TFP和Cd〓同时灌流脑垂体一段时间后，撤除TFP可使脑垂体分泌GtH显著增加，即出现"反跳"现象。
