Results Compared to the controlled groups,the lungs in cerebral hemorrhage groups existed hemorrhage,serosity exudation and inflammation infiltration(including macrophage and leucocyte),and the number of macrophage an...

结果与对照组比较，脑出血组肺组织存在明显渗出、出血及大量白细胞、巨噬细胞浸润，炎症细胞记数有显著意义P.05。结论脑出血可以通过引发炎症反应导致急性肺损伤；炎症反应在3~5d时最明显。

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.

本研究采用大鼠深低温颈总动脉阻断模型，应用流式细胞仪、电镜、原位缺口末端标记法、免疫组化法和RT-PCR技术分别检测深低温脑缺血对皮层神经细胞调亡的影响方法：第一部分深低温停循环脑保护大鼠模型的建立：SD大鼠20只，麻醉后气管插管辅助呼吸，用冰块将大鼠的体温降至(21±1)℃，阻断双侧颈总动脉，记录体温、心率、血压、血氧饱和度和血气分析，60分钟后恢复颈总动脉血流，用Longa等的5级评分标准评定4小时和24小时后大鼠神经系统损伤情况。

12H treatment group compared with 12h model group: the level of MCP-1 of the Gardenoside group decreased and MIP-1 is no different with the model group; the level of the MCP-1, MIP-1 of the Baicalin group are no different with the model group; the level of MCP-1, MIP-1 of the Concha Margatitifera Usta decreased than the model; the level of MCP-1 of the Cholic Acid group is no different and the level of MIP-1 decreased than the model; the level of MCP-1 of the Hefang Group decreased and the level of MIP-1 of it decreased than the model group.

合方治疗脑缺血24小时组缺血脑组织nNos光密度值较缺血24小时模型组明显降低（p＜0.01）。细胞的死亡分为坏死和凋亡两种方式，凋亡是细胞为避免对机体造成更大损伤而采取的一种程序性的死亡方式。珍珠母、胆酸、栀子苷、黄芩苷、合方治疗组较脑缺血24小时模型组可明显降低P53阳性表达，考虑药物抑制细胞凋亡可以起到对缺血脑组织的保护作用。

With a model of reversible middle cerebral artery occlusion in rats, the effects of Losartan on the water content of the brain, the contents of Evens blue and the expression of MMP9 were investigated after 24 hours of reperfusion following two hours of cerebral ischemia.
