This study measured the plasma and liver concentrations of cytokines, the distribution of blood lymphocyte subpopulations (CD4 and CD8), plasma levels of nitrite (NO₃⁻) and nitrate (NO₂⁻), intercellular adhesion molecule 1 (ICAM-1), cytokine-induced neutrophil chemoattractant 1 (CINC-1), prostaglandin E2 (PGE2), and peritoneal lavage fluid (PLF) levels of monocyte chemotactic protein 1 (MCP-1) and CINC-1 in order to examine the anti-inflammatory activity of the cinnamon extract in lipopolysaccharide (LPS)-exposed rats. The plasma concentrations of interleukin (IL)-1β, IL-6, and tumor necrosis factor α (TNF-α) were lower in the cinnamon extract groups than in the control group at both 2 and 5 h after LPS injection. Furthermore, the liver concentrations of IL-1β, IL-6, and TNF-α were lower in the cinnamon extract groups than in the control group at 5 h after LPS injection. Plasma IL-10 concentrations were higher in the cinnamon extract groups than in the control group at both 2 and 5 h after LPS injection, and liver concentrations of IL-10 did not differ significantly among all treatment groups at 5 h after LPS injection. The distribution of CD4 tended to increase, and that of CD8 tended to decrease in the cinnamon extract groups. The CD4/CD8 ratio was increased in the cinnamon extract groups. The plasma concentrations of NO₃⁻/NO₂⁻, ICAM-1, CINC-1, and PGE2 and the PLF concentrations of MCP-1 and CINC-1 exhibited a tendency to decrease in the cinnamon extract groups. These results indicate that cinnamon extract can exert functional anti-inflammatory effects.
