Here we report a method for performing a chronic constriction injury (CCI) of the infraorbital nerve (ION) in the rat as a component of a chronic pain model. The surgical approach to the ION is described together with the use of a modified dental syringe needle that simplifies placing two chromic gut ligatures around the ION. This method makes the surgical procedure easier, the nerve injury more consistent across animals and reduces secondary damage to the ION and surrounding tissue. Pain behavior testing together with immunostaining for markers of nerve injury in the spinal trigeminal nucleus show the suitability of this procedure as a model of orofacial pain.
在此,我们报告一种在大鼠中对眶下神经(ION)进行慢性压迫损伤(CCI)的方法,作为慢性疼痛模型的一部分。描述了对ION的手术入路,以及使用改良牙科注射器针头,该针头简化了在ION周围放置两个铬肠线结扎的操作。这种方法使手术过程更简便,不同动物之间的神经损伤更一致,并减少了对ION和周围组织的继发性损伤。疼痛行为测试以及对三叉神经脊束核中神经损伤标志物的免疫染色表明,该手术作为口面部疼痛模型是合适的。
