Figure 2. CaCl2 reversed resveratrol's effect, while EGTA and ryanodine potentiated the antinociceptive effects of resveratrol.
CaCl2 (25, 50, 100 and 200 nmol, i.c.v), EGTA (5, 15 and 30 nmol, i.c.v) and ryanodine (0.25, 0.5, 1 and 2 nmol, i.c.v) were administered 30 min before resveratrol treatment. Mean ± SEM, n = 8. *p < 0.05 and **p < 0.01, compared to the vehicle + resveratrol (10 or 20 mg/kg) group.
