Cytokine production by rat spleen cells. Rats spleen cells were isolated and cultured (1 × 106 cells/well) in the presence of 2.5 µg/ml concanavalin A (ConA) for 48 h at 37°C. The supernatants were then collected and stored at −80°C. The cytokine concentrations were determined by ELISA. Values are means ± SD. *p<0.05 compared with the Control group. (A) Interferon (IFN)-γ secretion for the Control (n = 6) and Resection groups (n = 7). (B) Interleukin (IL)-4 secretion for the Control (n = 6) and Resection groups (n = 7).
