查询词典 morphologic

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)。

主要观察指标：①多巴胺能前体细胞诱导分化后形态变化。②常见多巴胺能神经元标记基因在诱导分化前后过程中的表达。

As a supplement of conventional CT, CT perfusion imaging can reveal the perfusion informations of tissue or organs, such as hemodynamics, microcirculation status. It is helpful not only in finding morphologic changes, but also in providing functional and metabolizable information about the circulation parameters of hepatic diseases. So, it is valid for studying liver disorders by providing functional information, especial for the differential diagnosis and assessment for therapeutic response.

作为常规CT的一种补充，它能提供组织器官微循环状况、血流动力学变化等其它灌注参数，对肝脏病变除了能显示解剖形态学改变，还能了解血流动力学状态等反映功能、代谢变化的信息，在肝脏疾病的影像诊断与鉴别诊断等方面具有重要的作用，特别是对各种治疗方法的疗效评估及监测具有指导意义。
