ABSTRACT
Objective To explore the effect of ultrashort wave on macrophage polarization and inflammation response after spinal cord injury in rats. Methods A total of 96 Sprague-Dawley rats were randomly divided into sham group, model group and ultrashort wave group, with 32 rats in each group. The spinal cord injury model was established by modified Allen's method in the model group and the ultrashort wave group. The ultrashort wave group received ultrashort wave since the first day after modeling. BBB score was applied to evaluate the locomotion recovery. HE staining was used to as-sess the injury area, while immunochemistry, real-time PCR and Western blotting were applied to measure the mRNA and protein expression of inducible nitric oxide synthase (iNOS), arginase-1 (Arg-1) and tumor necrosis factor-α (TNF-α). Results Compared with the model group, the BBB score increased (P<0.05), the expression of iNOS and TNF-α de-creased, and the expression of Arg-1 increased (P<0.05). Conclusion Ultrashort wave therapy may promote macrophage polarization from M1 to M2, inhibit inflammatory re-sponse and promote recovery after spinal cord injury in rats.
