摘要:

坐骨神经损伤的动物模型通常被用于研究神经性疼痛以及轴突再生,其中手术后止痛剂的施用是动物福利的重要考虑因素之一,但是镇痛操作必须以不能干扰科学实验为目的。文章认为无论是丁丙诺啡或是乙酰氨基酚在双边坐骨神经手术后施用不会改变背根神经节感觉神经元中与创口愈合相关基因的系列表达。这些研究结果表明,在手术后使用动物护理机构和委员会通常建议的丁丙诺啡或乙酰氨基酚剂量不改变坐骨神经神经元到坐骨神经损伤的固有基因表达响应,以及许多与伤口愈合相关的基因。因此,手术后止痛剂的施用可能不会混淆采用这种损伤模型的转化研究结果。

Abstract:

Animal models of sciatic nerve injury are commonly used to study neuropathic pain as well as axon regeneration.
Administration of post-surgical analgesics is an important consideration for animal welfare, but the actions of the analgesic must not interfere with the scientific goals of the experiment. In this study, we show that treatment with either buprenorphine or acetaminophen following a bilateral sciatic nerve crush surgery does not alter the expression in dorsal root ganglion (DRG) sensory neurons of a panel of genes associated with wound healing. These findings indicate that the post-operative use of buprenorphine or acetaminophen at doses commonly suggested by Institutional Animal Care and Use Committees does not change the intrinsic gene expression response of DRG neurons to a sciatic nerve crush injury, for many wound healing-associated genes. Therefore, administration of post-operative analgesics may not confound the results of transcriptomic studies employing this injury model.
