Figure 2. Normal and acidic saline injections increase the number of c-Fos expressing cells in NVmes, but only with acidic saline does the level of expression remain elevated.

Figure 2

Graph showing the mean number ± S.E. of c-Fos stained NVmes cells in Unoperated Controls (open diamonds), and Experimental (open squares) and Control group (filled circles) at 4, 24 and 96 hours after injection. Asterisks above points: significance compared to the Control group. Asterisks below points: significance compared to Unoperated Controls. *, p<0.05; **, p<0.01.
