结果表明，在相同的配方条件下，同化学法制备的聚合物相比，辐射法制备的聚合物的酸值较低，分子量较高，分子量多分散系数较小。

Our data are showed that apoptosis parameters including DNA fragmentation, nuclear morphological change and sub-G1 fraction, appeared after 24 h by 5 μM rottlerin treatment. Furthermore, rottlerin caused a decrease in 72% of ODC protein expression and an increase in threonine, rather than serine and tyrosine dephosphorylation on ODC enzyme compared with the control after incubation for 10 h. To determine whether ODC could down-regulate rottlerin-induced apoptosis, HL60 cells were stably transfected with ODC cDNA. HL60-ODC cells exhibited a 2.5-fold increase in ODC protein compared with vector only (HL60-pcDNA3) or HL60 cells.

在我们筛选天然化合物实验中，发现rottlerin抑制鸟胺酸去羧化活性最具成效，之前的研究人员已知蛋白激Cd调节鸟胺酸去羧化的活性，因此在人类白血病HL60细胞处理rottlerin的实验中发现加入rottlerin二十四小时后，细胞进行计划性死亡，并可侦测到DNA片段、细胞核浓缩及sub-G1提增；而细胞处理药物十小时后与控制组细胞比较，观察到鸟胺酸去羧化的蛋白表现与活性下降50﹪以上；除此以外，测定鸟胺酸去羧化去磷酸化的情况，发现於酥胺酸位置有显著差异，而丝胺酸和酪胺酸位置并无差异。

It was found that, with the increasing of volume fraction of silver and conductor phase, sheet resistivities descend and there are critical thresholds. The average partical size of bismuth ruthenate and PbO-B_2O_3-SiO_2 glass was researched.

研究了各相粉体平均粒径对膜层性能的影响，结果表明：钌酸铋平均粒径越小，膜层的方阻值越小，电阻温度系数偏正，重烧变化率越接近零值，球磨工艺的极限平均粒径为0.56μm。

Additionally, the water fraction from wood extract can inhibit the root growth on Pak-choi. At 1000 μg/mL, after 72 h, the length ratio of root to shoot was 0.69, and the dry weight of Pak-choi root was only the 20.6% of control. But the extracts of Sapindus mukorossi have no influence on the growth of Pak-choi with normal growth 7 days.

此外，木材抽出物之水分离部则具有抑制胚根生长的作用，经浓度1，000 μg/mL处理72 h之小白菜，胚根与胚茎长比值为0.69，且其胚根乾重仅为对照组的20.6%，但无患子抽出物对正常生长7天后之小白菜并无显著抑制生长作用。
