The rats were administered either diclofenac (Dic; 10 mg·kg−1, p.o., t =−120 min), compound B (Cmpd B; 30 mg·kg−1, s.c., t =−30 min) or vehicle (Veh, 15% MBCD) at the time (t) indicated before the injection of either carrageenan (Carr) or vehicle (sham) in the hind paw. Terminal plasma samples were collected at 2 h post-carrageenan treatment (n= 4 per group) and cytokine levels (pg·mL−1) measured. The lower detection limits for the individual cytokines were as follows: TNF-α (1.7 pg·mL−1), IL-1α (43.4 pg·mL−1), IL-1β (23.1 pg·mL−1), IL-2 (46.6 pg·mL−1), IL-4 (2.8 pg·mL−1), IL-6 (11.4 pg·mL−1), IL-10 (49.8 pg·mL−1), IL-12 (14.2 pg·mL−1), INF-γ (5.8 pg·mL−1), GM-CSF (7.3 pg·mL−1).
