Proinflammatory cytokine expression. (A, B) IL-1β, IL-6, and IL-8 mRNAs in spleen and liver were increased in control lambs after intratracheal LPS instillation. Proinflammatory cytokine mRNAs in spleen and liver were decreased by rhSP-D. (C) Endotracheal LPS increased IL-1β, Il-6, and IL-8 mRNAs in the lung. Expression of IL-1β was decreased in the group treated with rhSP-D. (D) IL-8 concentrations in plasma were increased in the control group. Plasma IL-8 concentrations were kept low by rhSP-D treatment. *p < 0.05 versus control.
