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。

METHODS Acute incomplete ischemia was induced by ligaturing bilateral carotid arterise and cutting heads in mice, the survival time and asthmatic time were observed; the coagulation timewas measured by sheet glass method,and the blood viscosity was also assayed; the platelet aggregation induced by collagen were studied by turbdimetry in vitro.

采用结扎小鼠双侧颈总动脉造成急性不完全性脑缺血模型，观察平均存活时间；另取小鼠断颅后测定断颅喘息时间；采用玻片法，观察胡芦巴总皂苷对凝血时间的影响；采用比浊法；观察其对体外血小板聚集率的影响，并测定全血粘度。

Place short and long food chips in posterior occlusion of unilateral left side. When the masticated load was 3、5、7 kg, the displacement of abutments was measured by a LB-high sensitive laser transferring detector to calculate displacement, inclination and torsion of the abutment in mesial-distal, labial lingual and vertical and horizontal directions.

分别在左侧后牙区放置长、短食物片的咬合状态下，负载3 kg、5 kg、7 kg咬合力时，用高精度半导体激光位移测量仪测量并计算出同侧基牙在近远中向、颊舌向的水平位移和倾斜、垂直向的位移和水平旋转，统计分析不同牙尖斜度对基牙位移的影响。

Thirty-six rats ,weighing(250±10)g, were randomly divided into normal group, experimental group and control group.Orthodontical devices were put between the upper incisor teeth and dens molaris in both experimental group and control group.The corrective force was adjusted to 60g.Salvia miltiorrhiza combination was implanted to each rat in the experimental group every day.The animals of both experimental group and control group were killed at 7,14 and 21 days.The upper dens malarias and periodontal tissue slices were observed under the light microscope and transmission electro microscope,and the X-ray dental films were taken and measured with digitization dental scanning apparatus and its software.

以36只体重(250±10)g的雄性大鼠为样本，随机分为正常组、实验组和对照组，设定不同浓度丹参复合膜，以同体对照方式在正常组进行体内植入实验，在2周内观察不同浓度丹参的牙周组织诱导作用，寻找最佳应用浓度；在实验组和对照组的上切牙与磨牙之间隙安装正畸装置，建立大鼠磨牙移动实验模型，矫治力的大小为60g；实验组每日每只体内植入丹参复合生物膜，两组动物于正畸加力7、14、21d，分三批处死；处死后立即切取双侧上颌磨牙及牙周组织制取标本，制片透射电镜和光镜观察；拍摄X线牙片，用数字化牙科扫描仪及软件对其进行测量分析。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
