Methodssmear 0.25% croton oil＼acetone ag on the back of kunming mice,and observe the growth condition of papilloma,then record the quantity of tumor-bearing mice and the quantity of tumor in each mice.results20-ginsenoside rh2 prolonged the incubation of tumor, reduced the quantity of tumor-bearing mice and decreased the amount of tumor in each mice.conclusion20ginsenoside rh2 has obvious anti-papilloma effect on the mice skin.

结果20-人参皂苷rh2对小鼠皮肤乳头状瘤有明显的抑制作用，可使肿瘤发生潜伏期延长，使化学致癌物诱发的荷瘤动物数明显减少，每鼠荷瘤数显著下降。结论20r 人参皂苷rh2在预防癌症的发生和发展方面有重要的作用，也是很有前景的新型抗癌药。

Mass-spectrum scan is conducted for the remaining gas in insulating layer. It is discovered that, the steam, CO_2 and hydrocarbon are main factors affecting the vacuum degree of the layer. Degasification process shall be applied to remove the remaining gas and to extend the service life.

通过室内实验，对隔热夹层中的残气进行了质谱扫描，发现水蒸汽、CO2 和碳氢化合物是"污染"夹层真空度的主要因素，可应用除气工艺消除隔热夹层中的残气，以延长高真空隔热油管的使用寿命。

As for the humidity, the water electrodes can increasingly high concentrations of easily generated scale, the impact of the effect of steam generated, so in accordance with set procedures, the main control of the controller will work in the host after a certain period of time to open the drainage valve (according to different drainage water cycle settings), ranked out of high concentrations of water, automatically add new water to ensure a good humidifier humidification efficiency, and extend the useful life of the host.

随着加湿的进行，电极罐中的水浓度越来越高，极易产生水垢，影响蒸汽产生效果，因此根据程序设置，主控制控制器将在主机工作一定时间后打开排水阀（可根据不同水质设定排水周期），排掉高浓度的水，自动补充新水，确保加湿器良好的加湿效率以及延长主机使用寿命。

RESULT: In vitro, TISE at the concentrations of 760 and 380 mgL-1 had significant antagonistic effect on the normal bronchus slice contraction caused by histamine as well as on the sensitized bronchus slice contraction caused by egg albumin, but had no effect on the contraction caused by acetylcholine. in vivo, TISE at doses of 25 and 18 mgkg-1 could significantly prolong the latent period of expiratory dyspnea, tic and falling down caused by egg albumin in sensitized guinea pigs.

结果：离体实验，TISE 760，380 mgL-1对组胺致正常豚鼠气管片的收缩具有对抗作用，对卵白蛋白所致的致敏豚鼠支气管平滑肌收缩有极显著的抑制作用(P＜0.01)，而对乙酰胆碱所致气管片收缩无明显影响；整体实验，TISE 25，18 mgkg-1可显著延长卵白蛋白所致的致敏豚鼠呼吸困难、抽搐和跌倒的潜伏期(P＜0.01)。

RESULTS: hMSC had good homogeneousness and immunological reaction after implantation.

结果： 第5代呈集落生长的hMSC，均一性好。hMSC可在脑内存活6周以上；随着时间的延长，hMSC在脑内迁移的范围越来越大；间接免疫荧光表明hMSC在大鼠脑内表达人神经元特异性烯醇化酶、神经丝蛋白和胶质纤维酸性蛋白；模型鼠的肢体运动功能有明显改善。

Better constructability brings lower investment,shorter time limit and longer life cycle.

较好的可维护性带来的收益包括降低运营成本和生命周期费用、减少发生故障后的维修时间、延长产品使用寿命、降低故障率、减少计划外的运行暂停时间。

"It might take a little longer to put together, this provides much more clarity and predictability on what have to file," said Clay Lowery, the assistant secretary for international affairs at the US Treasury.

美国财政部负责国际事务的助理部长克莱·罗威表示："新规定可能会延长一点准备文件的时间，但它增强了必须提交的信息的明确性和可预见性。"

In addition, NOS activity decreased with the time prolonged in vitro, when oxyhemoglobin, a scavenger of NO, was applied, the NOS activity kept stable. This result above demonstrated that NO can inhibit NOS activity, and it was the inhibition of NOS activity by NO that may be an important protective mechanism to resist the neurotoxicity by Py.

另外，本实验还发现，在体外实验时，一氧化氮合酶活性可随时间的延长而逐渐下降，当向反应体系中加入氧合血红蛋白去除一氧化氮的作用后，则一氧化氮的抑制作用消失，酶活性保持稳定；以上结果表明一氧化氮对于一氧化氮合酶活性具有抑制作用，而且这种抑制作用，可能是机体对抗拟除虫菊酯毒性作用的一种重要保护机制。

The response of Pn to instantaneous lighfflecksdepended on induction state and lightfleck length;full induction shoots could response morerapidly than low or non-induction shoots;and the increase of lightfleck length could raise photoinduction thus to increase Pn.

针叶Pn对单个瞬时光斑的响应与光斑前的光诱导状态和光斑时间长短有关，充分诱导的针叶Pn光斑的响应要敏捷得多，光斑时间延长可提高光诱导状态。
