A Mechanical threshold before and after different treatments (The data were shown as mean ± SD, n = 5, ^#p < 0.05, ^###p < 0.001 was compared with Turkey’s multiple analysis between PBS and levobupivacaine, ***p < 0.001 was compared between RLBP and levobupivacaine). B Mechanical threshold before and after different treatments. The black arrows in the figure mean ultrasound irradiation. (The data were shown as mean ± SD, n = 5, ^#p < 0.05, ^###p < 0.001 was compared with Turkey’s multiple analysis between LBP + US and RLBP + US, *p < 0.05, **p < 0.01, ***p < 0.001 was compared with Turkey’s multiple analysis between RLBP and RLBP + US). C Mechanical threshold of mice treated by RLP, PBS, and PBS + US. The black arrows in the figure mean ultrasound irradiation. D Thermal latency before and after different treatments (The data were shown as mean ± SD, n = 5, ^#p < 0.05, ^###p < 0.001 was compared with Turkey’s multiple analysis between PBS and levobupivacaine, ***p < 0.001 was compared with Turkey’s multiple analysis between the RLBP and the levobupivacaine group). E Thermal latency before and after different treatments. The black arrows in the figure mean ultrasound irradiation. (The data compared with Turkey’s multiple analysis were shown as mean ± SD, n = 5, ^##p < 0.01, ^###p < 0.001 between LBP + US and RLBP + US, *p < 0.05, ***p < 0.001 was compared with Turkey’s multiple analysis between RLBP and RLBP + US). F Thermal latency of mice treated by the RLP, PBS, and PBS + US. The black arrows in the figure mean ultrasound irradiation. G Immunofluorescence assay of ipsilateral L5 DRG at 54 h after treatment with the RLBP + US, LBP + US, and levobupivacaine + US. The scale bars are 50 μm
