Objectives: In a previous study, we have shown that Gagam-Gongjin-Dan(GGD) has an inhibitory effect on the ovalbumin-induced immune responses and a hepatoprotective effect on actaminophen-induced liver injury in Balb/c Mice. However, the possible anti-inflammatory effect of GGD extract for inflammatory mediators was not reported. Therefore, the purpose of this study was to investigate an inhibitory effects of GGD extract against lipopolysaccharides(LPS) induced inflammatory mediators in mouse peritoneal macrophages.
Methods: GGD extract was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. Accumulated nitrite, an oxidative product of nitric oxide(NO), was measured in the culture medium by the Griess reaction. The levels of prostaglandin E₂(PGE₂), interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α) were measured by enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2(COX-2) were measured by Western blot analysis.
Results: GGD extract (50-400㎍/ml) per se had no cytotoxic effect in LPS-stimulated peritoneal macrophages. GGD extract dose-dependently reduced NO, PGE₂, IL-1β and TNF-α production and COX-2 activity caused by stimulation of LPS. The levels of iNOS and COX-2 protein expressions were markedly suppressed by the treatment with GGD extract in a dose dependent manner.
Conclusions : These results suggest that GGD extract has an anti-inflammatory effect against LPS-induced inflammatory mediators in peritoneal macrophages, these properties may contribute to inflammation disease care.
