Methods Rats were exposed to S band HPM which average power densities were respectively 2~90 mW/cm^2. HE staining, Toluidine blue staining and electron telescope were used to study the change of the structure of cortex, and high performance liquid chromatography was used to study the changes of 4 amino acids (glutaminic acid, asparagic acid, GABA and glycine) of cortex in 6 h and 1d after exposure to 10 and 50mW/cm^2 HPM.

Results: Neonatal rats in hypoxic-ischemicgroup behaved restlessness, cyanosis, deep and rapid breath, astasia, lethargy, irritation and spasm; There were local pyknosis, fragmentation, dissymmetry, blur or disappearance of nucleoli, raritas of ground substance in left cerebral cortex; but there was no statistic significance in chinese traditional medicine group and sham group. The expression of HIF-1α mRNA in brain tissue of experimental group and chinese traditional medicine group were higher than that in sham group, especially chinese traditional medicine group at 3d; HIF-1α positive cells were found in cerebral cortex and hippocampus. There were more HIF-1α positive cells in experimental group and chinese traditional medicine group and mainly in vascular endothelial cells.

结果 缺氧缺血后大鼠相继表现为烦躁不安、全身发给、呼吸加深加快、站立不稳、嗜睡、激惹或间断发作的痉挛和抽搐；HE染色显示实验组大鼠左侧大脑皮层出现局灶性神经元核固缩，核碎裂，核仁偏位，不清或消失，基质疏松；中药组大鼠脑组织结构基本接近假手术组，无明显水肿和坏死表现；实验组和中药组大鼠脑组织HIF-1α mRNA表达较假手术组明显增加，尤其是中药组实验第3日者；免疫组化显示实验组和中药组各时间点大鼠大脑皮层和海马区均可见不同程度的HIF-1α表达，明显高于假手术组，阳性表达主要在血管内皮细胞，海马和皮层的锥体细胞亦有HIF-1α阳性细胞分布。

MethodsNonheparinized autohemic blood of the rat was taken out from rat"s femoral artery and injected into its caudate nucleus immediately to establish a model of intracerebral hemorrhage.The changes of edema in the ipsilateral bassal ganglia , ipsilateral cortex, contralateral bassal ganglia and contralateral cortex were measured at 1,2,3,5 and 7 days respectively after intracerebral hemorrhage. The rat"s packed red blood cells, lysed red blood cells and hemoglobins at different concentrations were injected respectively into the rat"s caudate nucleus. The changes of edema in various regions of the brain at different time were measured as above. 5U thrombin was injected into the rat"s caudate nucleus and the changes of edema in various regions of the brain at different time were measured as above.

RESULTS: For the ketamine anesthesia groups, the decreased signal intensity was observed at sensory cortex (r=0.79, 19.5%), at motor cortex (r=0.81, 16.6%), at thalamus (r=0.66, 4.5%), and at callosal gyrus (r=0.68, 4.7%).

结果： 氯胺酮麻醉可降低感觉皮层、运动皮层的信号强度，其r值分别为0.79， 0.81，信号变化强度分别为19.5%， 16.6%；丘脑和扣带回区信号也受到抑制，r值分别为0.66， 0.68，信号变化强度为4.5%， 4.7%。
