Mechanical withdrawal threshold (MWT). Three to fourteen days after the operation, the pain threshold in the TN group significantly decreased compared with the shams. Palmatine treatment noticeably reduced pain sensitivity of TN rats. Data are presented as mean ± SD, n = 12. *p < 0.05 vs sham group; **p < 0.01 vs sham group; ##p < 0.01 vs TN group.
