Effect of POMC injection on levels of endorphin in muscle at days 3, 5, 7 and 14 after injection with CFA. Results are means ± SEM. Statistical comparisons between groups were made by analysis of variance; individual comparisons were made with the post-hoc test. *P < 0.05, showing a significant difference between rats receiving electroporation (SG VII) and CFA only (SG VIII).
