Serum samples (means ± SE) for the following were measured at baseline (0 h) and 3, 6, and 24 h using a multiplex bead-based assay and analyzed by ANOVA for time effect: tumor necrosis factor (TNF)α; interleukin (IL)-1β, −2, −4, −6, −8, and −10; interferon (IFN)γ; regulated on activation, normal T cell expressed and secreted (RANTES); macrophage inflammatory protein (MIP)1α and −1β; monocyte chemotactic protein (MCP)-1; eotaxin; and vascular endothelial growth factor (VEGF). NS, not significant.
