가감보중익기탕의 LPS 유도 염증성 매개물에 대한 억제 효과 = Kagam-bojungikgitang inhibits LPS-induced Inflammatory Mediators in RAW 264.7 Macrophages

다국어 초록 (Multilingual Abstract)

Kagam-bojungikgitang is the water extracts prepared from Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Astractylodis Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisiae iwayomogii Herba, and Scutellariae Radix. This is a modified prescription of Bojungikgitang, which has been used for the treatment of indigestion, and immunological disease in oriental countries. In this study, the effects of Kagam-bojungikgitang and Bojungikgitang on the production of prostaglandin E_2 (PGE_2) and the expression of cyclooxygenase-2 (COX-2) were examined using Raw 264.7 macrophages activated with lipopolysaccharide (LPS). Both prescriptions dose-dependently reduced the release of PGE_2 and expression of COX-2 caused by stimulation of LPS without cytotoxic effect. Kagam-bojungikgitang's inhibitory effects were better than Bojungikgitang in PGE_2 production and COX-2 expression. Moreover, Kagam-bojungikgitang also attenuated markedly the production of tumor necrosis factor (TNF)-α, and IL-6 than Bojungikgitang in LPS-stimulated RAW 264.7 macrophages. These results suggest that Kagam-bojungikgitang decrease PGE_2 and pro-inflammatory cytokine production in macrophages and these properties may contribute to the anti-inflammatory activity of Kagam-bojungikgitang.
