The extremities were titanic, and there was no response to touch stimulations.Our results suggested that Pentobarbital sodium inhibited neuronal firing through GABA_A receptors, therefore the local field potentials and neural firing rates were inhibited; Urethane acted on many kinds of receptors including inhibitory and excitory ones, so the local field potentials did not change significantly; however, because of the multiform receptors on the neurons, the changing of firing rates to different neurons were not the same; Ketamine mainly acted on the NMDA receptors, therefore the local field potentials and neural firing rates were enhanced, and most neural firing rates would be increased.

从这三种麻醉剂的底层作用机制来看，戊巴比妥钠通过作用于GABAA受体对神经细胞发挥抑制性作用，因此表现为场电位和神经元放电的降低；氨基甲酸乙酯同时作用于多种受体通道，既有兴奋性受体，也有抑制性受体，因此，对场电位的影响不大，但对单个神经元来说，每个神经细胞上的受体通道分布差异较大，因此，单个神经元的放电频率变化会有所不同；盐酸氯胺酮主要作用于兴奋性的NMDA受体，故整体场电位活性增加，多数神经元的放电频率也会有所升高。

In a dose-dependent manner, Gambogic acid arrested cell cycle of Jurkat and Raji cells at G0/G1 phase, the percentage of which increased from 41.78% to 62.72% and from 40.23% to 67.30%, respectively.

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)。
