Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.

结果平均功率密度10，50和90mW/平方公分S波段高功率微波可引起大脑皮层神经元固缩、深染，尼氏体减少；突触结构模糊，囊泡堆积；髓鞘融合、解离等。10和50mW/平方公分组照后6h大脑皮层上述4种氨基酸含量均显著增高(P.01)；而照后ld仅见γ-氨基丁酸和甘氨酸含量仍较高(P.01)。

The facial nerve severely demyelinated and axons retrogressively changed in Saline group but mild in Mailuoning group.

生理盐水组面神经纤维溃变明显，髓鞘松解分离，轴突肿胀有空泡或全部消失；脉络宁组面神经病变较轻。

In the suboesophageal ganglion, 5-HT/TPH-likeimmunoreactive neurons (ca.15) mainly distributed in the lateral and ventro-lateral area, withprocesses projecting into the suboesophageal ganglion neuropil.

咽下神经节处5-HT/TPH阳性神经元数目相对较多，每侧大约有15个，主要分布于髓区侧细胞体层和腹侧细胞体层，轴突投射进入咽下神经节。

Objective To study the pathogenesis and clinical symptoms of patient with central type of interˉvertebral disc protrusion manifested intermittent claudication as the mainly clinical presentation,so as to reach the early diagnosis and treamtmet in time.Methods In58cases,X-ray film,lumbar discography,CT examinations were done to confirm the diagnosis,then total laminectomig was performed to reveal the vertebal body without involving small arˉticular process.Intervertebral tissue was excised via duralotomy approach in2cases in remaining56cases,through right and left longitudinal syndesmotomy to resect the nucleus pulposus of lumber intervertebral disc.Results In58cases treated by operation,the operative findings were in according with the X-ray and CT examinations ofpre-opˉeration.

目的 对呈间歇性跛行主要临床表现的中央型椎间盘突出症患者的发病机制和临床表现进行研究，达到早诊断、早治疗方法对58例患者进行X线拍片，腰椎碘造影，CT扫描检查，根据检查结果确诊后，采用全椎板切除显露椎体，未累及小关节突，2例经硬膜切开入路切除间盘组织，余56例经从双侧用神经剥离子带棉片将硬脊膜带神经根向中线剥拉至显露圆形突出物止，分别从左右纵韧带摘除髓核。

In both inflammatory and healthy gingival epithelium, CD14 mRNA positive cells, which are mainly located at thornlike cell layer, were found.

另一方面，牙髓组织除树突状细胞外CD14表达细胞很少，牙龈组织皮下的成纤维细胞和未分化细胞也不表达CD14。

After embeding routingly,serial 10μm sections were prepared for modified trichromic staining with improve-ments to manifest axons and myelin sheaths simultaneously,immunohistochemistryand in situ hybridization.

组化染色用新的改良三色法同时显示神经轴突和神经髓鞘。

Not myeloid dendritic cells, express TLR9, the receptor for unmethylated CpG motifs that are abundant in bacterial DNA.

髓系树突状细胞不表达TLR9 ，该受体的甲基CpG基序中有丰富的细菌DNA 。

Results: Dynamic observation with histopathology and immunohistochemical staining showed that, after the nerve root nerve root compression, the myelinated nerve fibers decreased and there was ultrastructure changes of the nerve fibers, such as Schwann cell cytoplasm swelling and edema, Wallerian degeneration, and demyelinated degeneration of axons.

结果：通过对压迫神经根及神经根节大体观，组织病理学和免疫组织化学的光学显微镜的动态观察，可见神经根压迫后其有随神经纤维数目减少和超微结构的改变，如神经模细胞胞质肿胀和细胞水肿、华勒变性、神经轴突脱髓鞘变等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
