Abstract

Background: Physical therapy with whole body vibration (WBV) following compressive spinal cord injury (SCI) in rats restores density of perisomatic synapses, improves body weight support and leads to a better bladder function. The purpose of the study was to determine whether the combined treatment with WBV plus erythropoietin (EPO) would further improve motor, sensory and vegetative functions after SCI in rats.

Methods: Severe compressive SCI at low thoracic level was followed by a single i.p. injection of 2,5μg (250 IU) human recombinant EPO. Physical therapy with WBV started on 14th day after injury and continued over a 12-week post injury period. Locomotor recovery, sensitivity tests and urinary bladder scores were analysed at 1, 3, 6, 9, and 12 weeks after SCI. The closing morphological measurements included lesion volume and numbers of axons in the preserved perilesional neural tissue bridges (PNTB).

Results: Assessment of motor performance sensitivity and bladder function revealed no significant effects of EPO when compared to the control treatments. EPO treatment neither reduced the lesion volume, nor increased the number of axons in PNTB.

Conclusions: The combination of WBV + EPO exerts no positive effects on hind limbs motor performance and bladder function after compressive SCI in rats.

促红细胞生成素和全身振动联合治疗后脊髓压缩性损伤大鼠的运动、敏感和营养恢复。

背景:大鼠压缩性脊髓损伤(SCI)后全身振动物理治疗(WBV)可恢复核周围突触密度，改善体重支撑，改善膀胱功能。本研究的目的是确定WBV联合促红细胞生成素(EPO)是否能进一步改善大鼠脊髓损伤后的运动、感觉和营养功能。方法:重度低胸段压缩性脊髓损伤患者单次腹腔注射2.5 μg (250 IU)人重组EPO。WBV物理治疗于伤后第14天开始，并持续12周。在脊髓损伤后1、3、6、9和12周分析运动恢复、敏感性测试和膀胱评分。闭合形态学测量包括病变体积和保存的病灶周围神经组织桥(PNTB)的轴突数量。结果:运动表现敏感性和膀胱功能的评估显示，与对照组相比，EPO没有显著影响。EPO治疗既没有减少PNTB的病变体积，也没有增加轴突的数量。结论:WBV + EPO联合应用对大鼠压缩性脊髓损伤后后肢运动功能和膀胱功能无积极影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
