Effects of Angelicae Gigantis Radix pharmacopuncture on Nitric Oxide and Prostaglandin E2 Production in Macrophage
Abstract
Objectives: Angelicae Gigantis Radix has been known traditional medicine with antimicrobial activities and it has been widely used for treatment of blood and inflammatory diseases. In the present study, some studies examined anti-inflammation effects of Angelicae Gigantis Radix but they usually were performed by ethanol extracted Angelicae Gigantis Radix pharmacopuncture. So We investigated the inhibitory effects of Angelicae Gigantis Radix pharmacopuncture by hot water and ethanol extract on Nitric oxide(NO) and Prostaglandin E2(PGE2) production in lipopolysaccharide(LPS) induced macrophage cell. Methods: Angelicae Gigantis Radix was extracted by ethanol and hot water. Cell viability was determined by MTT assay. To evaluate anti-inflammation effects of Angelicae Gigantis Radix pharmacopuncture, we examined NO and PGE2 production in LPS induced macrophages. The concentrations of NO and PGE2 were measured by Griess assay and Enzyme Immuno-Assay. Results: 1) The MTT assay demonstrated that cytotoxic effect of Angelicae Gigantis Radix pharmacopuncture by hot water extract and ethanol extract in RAW 264.7 macrophage cells were not appeared. 2) Angelicae Gigantis Radix pharmacopuncture by ethanol extract and hot water extract inhibited NO production in LPS induced macrophages significantly. 3) Angelicae Gigantis Radix pharmacopuncture by ethanol extract tended to inhibiting PGE2 production in LPS induced macrophages. And Angelicae Gigantis Radix pharmacopuncture by hot water extract inhibited LPS induced production of PGE2 in RAW 264.7 macrophage cells significantly. Conclusions: This study suggests that Angelicae Gigantis Radix pharmacopuncture may have an anti-inflammatory property through the inhibition of NO and PGE2 production in LPS induced macrophages. It may have a therapeutic potential for the treatment of various inflammatory diseases.
