Fig. 2From: Stage-dependent anti-allodynic effects of intrathecal Toll-like receptor 4 antagonists in a rat model of cancer induced bone painThe effects of naloxone on cancer induce pain. Naloxone (60 μg, i.t.) increased PWT significantly at day 8 after surgery (a), while increased PWT only at 45 min after i.t. injection in the contralateral paw at day 16 (b). *P < 0.05 versus NS-treated ratsBack to article page
