The good catalytic performances were obtained on those catalysts supported by SiO_2. With the increasing calcination temperature from 300℃to 700℃, Co_3O_4 particles augmented and sintered on the samples surface which contained 10 wt.% cobalt, the crystallite size of Co_3O_4 was aggrandized from 7.2 nm to 20.3 nm by inchmeal. On the other hand, the activation energy for the combustion reaction was increased linearly with the augment of average crystallite size of Co_3O_4, the TOF value on prepared catalyst was decreased with it. Thus, the catalytic combustion was a typical structure-sensitive reaction.

在钴含量为10 wt%的样品上，随着焙烧温度由300℃提高到700℃，钴物种出现迁移团聚甚至烧结，在XRD中测定的Co_3O_4晶粒尺寸由7.2 nm逐步增加至20.3 nm；另一方面，催化剂的燃烧活化能随样品上Co_3O_4晶粒的平均尺寸增加而呈现线形增加趋势，而单位时间内单位活性物种上的甲烷转换频数随着粒径增加而逐渐降低，这一现象证实了该反应属于典型的结构敏感反应。

The expression changes of relating-apoptosis gene proteins (bcl-2, bax) were detected by immunohistochemistry before and after treating with the Agaricus Blazei Murill extract to explore the possible mechanisms of inducing apoptosis for MGC-803 cells in vitro. Results: The Agaricus Blazei Murill extract significantly inhibited the proliferation of gastric cancer cells in vitro and the inhibitive effects were depended on the medicine concentration and treating times. After treating 24 hours on the gastric cancer cells with the morphologic changes of apoptosis with chromatin margination, karyopyknosis, karyorrhexis were found by the light.

结果：(1)通过细胞培养和MTT法，表明长白山姬松茸在体外对MGC-803细胞株有明显的抑制作用，加药组与对照组相比其生长抑制率有显著性差异(P＜0.01)，而且这种抑制作用呈现浓度和时间的依赖性；(2)通过集落形成率的测定结果表明，加药组与对照组相比其集落形成率和集落形成抑制率有明显差异(P＜0.01)，说明长白山姬松茸对MGC-803胃癌细胞株有明显抗增殖作用；(3)光镜观察结果表明，加药组可见细胞脱水浓缩伊红染色增强，胞体缩小，内含高度浓缩的胞核呈深蓝色等典型细胞凋亡形态；经AO／EB荧光染色观察结果表明，当终浓度为1.0mg／ml的姬松茸提取物作用于MGC-803胃癌细胞24h后，其凋亡率和破膜率与自然凋亡率与破膜率相比，均有显著性差异，其凋亡率86.3％(P＜0.001)，破膜率为41.6％(P＜0.01)，说明姬松茸确实有诱导MGC-803胃癌细胞凋亡的作用，同时也有细胞毒作用，但以诱导细胞凋亡为主；(4)免疫组化结果表明，用药前后凋亡相关基因的BCl-2、Bax蛋白均有显著性的改变(P＜0.001)。
