title: [REACTIVE CHANGES IN SPINAL CORD MOTONEURONS AFTER SCIATIC NERVE INJURY AFTER HIGH-FREQUENCY ELECTROSURGICAL INSTRUMENT APPLICATION].
abstract: A new experimental model for tissues connection at peripheral nerve injury site in form of tissues welding was designed. In current study we investigated motoneuron state 1, 3, 6 and 12 weeks after peripheral nerve injury and surgical repair with high-frequency electrosurgical technology. Spinal cord sections was stained by Nissl method and observed with light microscopy. We found that postoperative period in animals from experimental groups characterized by qualitative changes in neurons from spinal motor centers that can be interpreted as compensatory processes as response to alteration. In animals from group with high-frequency electrosurgical technology usage stabilization processes passes more quickly comparatively to animals with epineural sutures. High-frequency electrosurgical technology usage provides less harmful effects on motoneurons than epineural suturing.
