方法:將體外培養的雪旺細胞結合纖連蛋白植入大鼠半切損傷的脊髓內,用脊髓誘發電位及圖像分析方法比較治療組和對照組誘發電位潛伏期,再生軸突計數及二者間的關系。One of the major reasons of the failure of cns axon regeneration is the presence of many inhibitory molecules, mostly originated from cns myelin
目前認為cns軸突不能再生的主要因素之一是cns內存在眾多的抑制因子,髓鞘是抑制因子的主要來源。Methods : fifty paired embalmed cadaveric humeri ( twenty - five pairs : fourteen from male donors and eleven from female donors ) were scanned in medial - lateral ( ml ) and anterior - posterior ( ap ) position according to the humeral retroversion by ct. images of the humeri in the transverse planes at the lowest border of neck ( lbn ), 20mm and 40mm distal of lbn ( lbn - 20 、 lbn - 40 ), isthmus, head - neck anterior - posterior ( hn - ap ) were obtained. sixty - one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head - shaft angle, head to tuberosity height ( ht ), head thickness, curvature radius, articular surface arc ( sa ), neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including lbn, lbn - 20, lbn - 40 and isthmus
方法: 50根成對防腐肱骨(男14對,女11對)按肱骨頭扭轉角置於冠狀位和矢狀位,行肱骨全長,頭頸矢狀面,解剖頸下緣及其下20mm 、 40mm ,髓腔狹窄部四平面ct掃描,由ct軟體測量冠、矢狀位髓腔內外參數共61項,包括頭心?干軸距,頭位置,頭干角,頭?結節高度差,頭厚度,頭半徑,關節面張角,解剖頸直徑,髓腔狹窄部位置,解剖頸下緣及其下20mm 、 40mm和狹窄部四個平面髓腔的最大冠、矢狀徑,皮質骨厚度等。The animal experiment is carried out in the first hospital of shanghai through renovating the injured nerve of the rats. four projects are used in this experiment : the conduits coated with pgla, the conduits coated with chitosan, the conduits coated with chitosan adding bridge - yarn and self - nerve migration. after 12 weeks, we observe and analyze the thickness of marrow theca, the diameter of axone, the density of regeneration nerve and then do electromyography and statistics analyzing, finding out that the third conduits have the best recovering effects on the injured nerve, close to the self - nerve migration
因此我們選用加筋結構神經導管進行動物實驗。本課題動物實驗在上海市第一人民醫院進行,分別通過加筋結構塗pgla導管、加筋結構塗甲殼胺導管、加筋結構塗甲殼胺並加載縫芯線導管和自體神經移植四種方案對大鼠進行損傷神經修復實驗。在術后12周對四種方案再生神經的髓鞘厚度、軸突直徑、數量密度進行觀察分析,並進行肌電圖檢測和統計學分析。Fos + / th + / gfap + and fos + / vp + / gfap + triple labeled n - asc could be found in the mvz, pvn and son respectively ; ( 2 ) under electronic microscope, the astrocytic processes connected closely with the dendrites or axons of the neurons, where the bilateral membranes became thick. we call transiently it electron - dense areas ( edas ). the number of edas increased remarkably following hyperosmotic stimulation ; ( 3 ) when trace retrogradely, wga - hrp was microinjected into the unilateral son, pvn or nucleus of solitary tract ( nts ) respectively using the stereotaxic method, the n - ascs formed by the neurons triple - labeled with hrp / fos / th ( or vp ) and astrocytes labeled with gfap could be found in the mvz, son and pvn respectively ; ( 4 ) after being treated with heperosmotic nacl solution, intracellular calcium concentration in cultured hypothamic neurons and astrocytes increased and then decreased
腦內gfap陽性結構也明顯增多,其分佈與fos陽性細胞分佈基本一致,表現為胞體肥大、突起粗長; ast緊密包繞在神經元周圍形成神經元- ast復合體( n - asc ) ;在mvz 、 pvn和son三重免疫組化染色切片上可見到fos + th + gfap +第四軍醫大學博士學位論文和fos vp gfap三重標記asc ; ( 2 )免疫電鏡下son內星型膠質細胞突起與神經元樹突或軸突之間接觸部位出現增厚的膜結構一電于緻密區( edas ) ,高滲刺激后數量明顯增多: ( 3 )將們個mp注入大鼠一側n卜、卜卜或孤束核( ws ) ,分別在延髓內臟帶( mvz ) 、 so和pvn內出現fos hrp th 、 fos hrp八p三重標記神經元和gfap陽性標記ast形成的n asc ; ( 4 )高滲刺激使培養神經元和ast內鈣水平先升高后降低,最後維持在比高滲刺激前稍高的靜息鈣水平上。Biomechanical change in exterior and interior medullary cavity at fracture end during axial compressing of external fixator in vivo
外固定器軸向加壓骨折端髓內外在體的生物力學變化Conclusions : schwann cells together with fibronectin grafted to hemi - resected lumbar spinal cords in adult rats can promote partial conductive function repair of scathing spinal cords
結論:雪旺細胞結合纖連蛋白移植具有促進脊髓損傷后軸突再生的作用,並能部分恢復脊髓的傳入功能。Nogo protein expressed by cns myelin is regarded as a major repulsive factor for the failure of cns axon regeneration. the interest in this protein stems principally from the neurite growth promoting effect of a monoclonal antibody ( in - 1 ) rasied against ni - 250 which has been proved later to be a part of nogo - a
近年來認為髓鞘表達的ni - 250和ni - 35蛋白可能是cns軸突再生失敗的主要因素,用ni - 250作為免疫原制備的單克隆抗體in - 1可識別ni - 250和ni - 35 , in - 1的體內研究結果奠定了ni - 250和ni - 35作為中樞神經再生中最重要的抑制因子的地位。Others ( including my colleagues and me ) subsequently revealed the birth of new neurons, a phenomenon called neurogenesis, in the brains of adult birds, nonhuman primates and humans [ see “ new nerve cells for the adult brain, ” by gerd kempermann and fred h
幾個研究團隊指出,成年動物腦部與脊髓神經細胞的軸突(或主要分枝) ,在受傷后還可以復原到某種程度。分享友人
