【摘 要】目的探讨嗅球成鞘细胞(OECs)在坐骨神经损伤后促进神经功能恢复中的作用。方法SD大鼠30只随机分成对照生理盐水(SAL)组和实验(OECs)组,采用硅胶管套接大鼠切断的坐骨神经,硅胶管内对照组给予SAL,实验组给予培养成活的新生大鼠OECs悬液,分别于术后30或90天,应用电生理检测、HRP逆行示踪法及轴突图像分析检测损伤的神经在电传导轴浆运输、髓鞘再生等方面的恢复情况。 结果 术后30和90天,OECs组与SAL组比较:①OECs组损伤侧下肢复合肌肉动作电位(CMAP)的潜伏期(lat)分别缩短了0160ms和0156ms;神经传导速度分别加快了6.42mös和5.36mös;波幅分别增加了3.92mv和5.84mv;②OECs组损伤侧脊髓前角HRP阳性细胞率分别增加了11.63%和25.01%;③OECs组坐骨神经纤维数目分别增加了1047个ömm2和1422个ömm2;神经髓鞘厚度分别增加了0.43Lm和0.63Lm。 结论 嗅球成鞘细胞对周围神经损伤后的神经功能恢复有积极的促进作用。【关键词】 周围神经 损伤 嗅球成鞘细胞 功能恢复

Introduction to GPS ToolKit Pro 1.0 GPS ToolKit Pro is an ActiveX object that makes it easy to add GPS support to any Visual Basic, Visual C++, Delphi, Excel, or scripting project that supports ActiveX controls. GPS data (including lat/lon, speed, course, altitude, and dozens of other datasets) can be accessed through GPS ToolKit s properties, and GPS ToolKit s multithreaded event-based architecture notifies your application when data has been updated, saving you from having to write messy polling routines.

Generate a great circle "trajectory" from [lat1,lon1] to [lat2, lon2]. % Resulting points will be seperated by approximately delta_ft feet. % By default, delta_ft = 100 feet. All lat/lon inputs & outputs are in % degrees.
