Alterations in serum levels of TNF-α (A), TNF-α gene expression in the small intestine (B), serum levels of IL-6 (C), and IL-6 gene expression in the small intestine (D) at 20 h after radiation combined injury (RCI) with treatment by normal saline (Vehicle) or human ghrelin (Ghrelin) or sham operation (Sham). Data are presented as means ± SE (n = 4–6/group) and compared by ANOVA and Student-Newman-Keuls method: *P< 0.05 versus Sham group; #P< 0.05 versus Vehicle group.
