Fig. 8From: Morphine immunomodulation prolongs inflammatory and postoperative pain while the novel analgesic ZH853 accelerates recovery and protects against latent sensitizationRegression analyses of IHC markers versus von Frey scores. Individual scores for both von Frey at the time point just prior to perfusion and integrated density (or cell count for pp38) from both paradigms of CFA and drug treatment were plotted for all drug groups. pp38 and P2X7R are consistently correlated with pain. P values are listed on each graphBack to article page
