In order to find the new hepatoprotective agents preliminary screening of twelve prescriptions which have been used for the treatment of hepatic disease in Oriental traditional medicine has been carried out. Both DPPH free radical scavenging and hepatoprotective effect on tacrine-induced cytotoxicity in Hep G2 cells are performed. Osumokkya-tang which is one of the prescription belongs to interior-warming properties showed the DPPH free radical scavenging effect as well as hepatoprotective activity significantly. It is also suggested that its hepatoprotective effect is derived from Chaenomelis Fructus.

Bojungikgitang is the water extracts prepared from Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Astractylodis Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Bupleuri Radix, Cimicifugae Rhizoma, which has been used for the treatment of indigestion, and immunological disease in oriental countries. In this study, the effects of Bojungikgitang on the productions of nitiric oxide (NO) and prostaglandin $E_2\;(PGE_2)$, and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were examined using RAW 264.7 macrophages activated with $interferon-{\gamma}\;(IFN-{\gamma})$ plus lipopolysaccharide (LPS). Bojungikgitang (10-400 ${\mu}$g/ml) per se had no cytotoxic effect in unstimulated macrophages, but this compound dose-dependently reduced the release of NO and $PGE_2$ caused by stimulation of $LPS/IFN-{\gamma}$. The levels of iNOS and COX-2 protein were markedly suppressed by the treatment with Bojungikgitang in a concentration dependent manner. Moreover, Bojungikgitang also attenuated the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (1L)-1${\beta}$ and IL-6 in LPS-stimulated RAW 264.7 macrophages. These results suggest that Bojungikgitang decreases the NO and $PGE_2$ production in macrophages by inhibiting iNOS and COX-2 expression and these properties may contribute to the anti-inflammatory activity of Bojungikgitang.

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.
