Production of IL-1β cytokine by mouse peritoneal macrophages exposed to 2 μg/mL LPS, 10 μg/mL HSO, or LPS+HSO for 6, 24, or 48 h. Triplicate culture supernatants were pooled and assayed in duplicate. Data shown are the mean values±standard deviations. *P<0.05 and **P<0.01 compared to corresponding controls (cultured peritoneal macrophages).
