Figure 3From: Genetic knockout and pharmacologic inhibition of neuronal nitric oxide synthase attenuate nerve injury-induced mechanical hypersensitivity in miceEffect of intrathecal (i.th.) injection of L-NAME or D-NAME on mechanical pain hypersensitivity on day 7 after L5 spinal nerve injury in WT mice. Paw withdrawal responses to 0.24 mN (A and C) and 4.33 mN (B and D) mechanical stimuli on the ipsilateral (A and B) and contralateral (C and D) sides. **P < 0.01 vs the corresponding baseline. ##P < 0.01 vs the post-drug, D-NAME-treated group.Back to article page
