Fig. 1From: Hypomethylation of nerve growth factor (NGF) promotes binding of C/EBPα and contributes to inflammatory hyperalgesia in ratsDynamic changes of paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) after CFA treatment. a 1 day after injection, the PWT of the CFA injection group (CFA) was significantly decreased (**P < 0.01, compared with the corresponding saline control group (Saline), n = 7). b The PWL was also significantly decreased in the CFA group compared to the corresponding saline-treated control group starting at 1 day after injection (**P < 0.01, n = 7)Back to article page
