From: Altered neuronatin expression in the rat dorsal root ganglion after sciatic nerve transection
Evaluation of hyperalgesia induced by rat sciatic nerve transection (neurectomy). Pain threshold was estimated in the rat paw pressure test applied before (time 0), and on days (d) 1, 3, 5, and 7 after surgery in male S-D rats of approximately 8 weeks of age. Sham-operated (Sham) rats were subjected to the same surgical procedure, without manipulation of the nerve. Time 0 corresponds to pain threshold measure before surgery. Data represent mean values ± S.E.M. for 10 rats per group. There was significant difference to the values obtained before surgery (time 0). There was also significant difference to the values of Sham group (* P < 0.05).
