Testicular focal atrophy – tubular blockade as partial degeneration of the tubule

This study investigated whether focal atrophy is a degenerative process of a whole tubule or tubular blockade as partial intratesticular degeneration. Serial section analyses of testicular tissue from 19 men with different andrologic diseases were examined. From every fifth section of any series, defined areas were viewed under a light microscope, and tubule sections were drawn. Three-dimensional reconstructions were made from these materials. Reconstructions of the seminiferous tubules showed tubular blockade as partial degeneration of the tubules. Transition from an intact portion to a blockade was accompanied by an increase in the thickness of the lamina propria. The blockade was a cell cord that contained Sertoli cells and, at most, spermatogonia, or it was a completely atrophied tubule, a so-called tubular scar. In a given tubule, defined areas of atrophy and areas of spermatogenic activity were both found. Occurrence of tubular blockade increased with age. Serial section analyses of testicular tissue showed tubular blockade as the partial degeneration of seminiferous tubules. In focal atrophy, a given tubule can have defined areas of atrophy and areas of spermatogenic activity. Received: 25 August 1999 / Accepted: 21 April 2000     

面神经液压与面神经电图的相关性研究

目的　探讨面神经电图作为面神经减压手术指征的病理生理学基础。方法　利用电生理仪和伺服微变量微压系统 ,对正常和压榨伤后面瘫不同时期的豚鼠 ,作面神经电图检查 ,再采用微创测压法进行面神经液压的测量 ,得出面神经损伤后不同时期的面神经动作电位降幅及相应的面神经液压 ,并观察不同时期面神经光镜和电镜下的组织学改变。结果　面神经损伤 3d至 3周 ,随着面神经液压的升高 ,面神经动作电位降幅百分数亦增加 ,二者间有明显相关性 ,损伤后 2周和 3周 ,面神经液压和面神经动作电位降幅的相关系数分别为 0 88和 0 51。神经液压的变化与面神经Wallerian变性各期组织学改变相一致。结论　在面瘫 3周内 ,面神经电图的改变可间接反映面神经液压的变化 ,并可为面神经减压术的时机提供客观、可靠的实验依据。     

钛钢螺纹椎体融合器治疗退行性腰椎间盘突出症的远期疗效观察

目的　观察钛钢螺纹椎体融合器 (TFC)手术治疗退行性腰椎间盘突出症的远期疗效。方法　选择 36例腰椎间盘突出症患者 ,随机分为 2组各 18例 ,治疗组采用TFC手术治疗 ,对照组采用单纯椎板开窗、髓核摘除术治疗。治疗后进行融合率、椎间隙高度、椎间孔高度观测和主、客观疗效评价。结果　治疗组椎体融合率达 94 % ,术后椎间隙高度及椎间孔高度增加 ,远期随访无明显丢失 ,临床疗效主客观评估均优于对照组。结论　TFC治疗退行性腰椎间盘突出症 ,可以有效地撑开或保持受累椎间隙 ,扩大椎间孔 ,有利于骨融合 ,可缓解疼痛 ,其远期疗效可靠。     

TREATMENT OF 247 CASES OF PROLAPSE OF LUMBAR INTERVERTEBRAL DISC WITH COMPREHENSIVE PLUM-BLOSSOM MAGNETIC NEEDLE THERAPY
