Outcome:(1) Acute ischemic damage may induce the expression of c-fos protein in Cerebral Cortex quickly. Also, the expression increases by the ischemia time delay. It may hint that ischemia injury can rise the ability of nerve cells to tolerate ischemia and anoxia. And the expression level of c-fos can be up-regulated by putting blood of 12 hand Jing Points. So we think that treated by this therapy can rise the irritability of brain to resist the development of ischemia and enhance the ability to plerosis.(2) Acute ischemic damage may induce the expression of HspVO in Cerebral Cortex quickly. Also, the expression increases by the ischemia time delay. It may hint that ischemia injury can rise the ability of nerve cells to tolerate ischemia and anoxia.

Objective To study the statement of immunoreaction of c Jun and functional recovery of spinal cord injury in rats after fetal spinal cord transplantation.Methods Experimental rats were divided into two groups:spinal cord hemisection injury combination with transplants of FSC to injured site group,and spinal cord injury that received gelfoam pledgets group.On the lst,3th,7th,14th and 28th day after operation,6 animals in each group at each time phase,were observed for their function recovery with the methods of praxiology and electro physiological examination,the animals were then sacrificed for the observation of the statement of c Jun reaction by immnochemistry method and computer image analysis system was used for quantitative analysis.

目的：研究大鼠胚胎脊髓移植后能否影响，c-Hun免疫反应的表达和脊髓损伤后大鼠功能的恢复，方法；将动物分为脊髓半切洞损伤加胚胎脊髓移植组和单纯脊髓板切洞损伤加明胶海绵填塞组，每个时相点每组6只动物，术只1，3，7，14和28天，应用行为学和电生理检查观察大鼠功能恢复情况，应用免疫细胞化学方法，c-Jun免疫反应的表达，采用计算机图像分析技术，进行定量分析。

Secondly,UV spectrophotometry was adopted to research the combination action on SM_2 and SIZ with MAA and 4-Vp.The combination action of functional monomer with template molecules were produced in the results. Then,the prediction imprinting principle of SM_2 and SIZ were given. The diagrams of infrared spectrum were analysed in MAA and 4-Vp and IMPs of SM_2. It was discoved that the absorbability peak of C=C function group in the IMPs were turn to be very low ,but the function group of carboxylic acid and pyridyl in the IMPs were no evidence change, and the condition was created in the molecular recognition of MIPs. Thermal Analysis was adopted to research IMPs ,in which ,a better thermal stability and its decompose temperature were showed in the results.

其次，本文利用紫外分光光度法研究磺胺二甲嘧啶和磺胺异噁唑与甲基丙烯酸或4-乙烯基吡啶的结合作用，结果表明，溶液中的功能单体与模板分子之间产生了结合作用，并预测磺胺二甲嘧啶和磺胺异噁唑印迹机理；分别分析了功能单体甲基丙烯酸、4-乙烯基吡啶、磺胺二甲嘧啶和磺胺异噁唑分子印迹聚合物的红外谱图，经过对比发现制得的印迹聚合物中C=C双键峰很小，并且功能键羧酸键和吡啶氮没有明显变化，这为聚合物特异识别特性创造了条件；利用综合热分析仪，对分子印迹聚合物进行综合热分析，结果表明分子印迹聚合物具有较好的热稳定性，分解温度也较高。
