Effect of STEA administration on the serum level of inflammatory cytokines. The preventive (A) and therapeutic (B) effects of STEA administration on the serum levels of inflammatory cytokines in rats with TNBS-induced colitis were investigated. Colitis induced by TNBS infusion and administration of STEA were performed as described in the experiment methods. Sera were collected at the indicated times, and cytokines levels were measured by ELISA. Results represent mean ± SE . **p < 0.01 and *p < 0.05 vs TNBS-treated rats; ^p < 0.05 vs control rats.
