Abstract
|
|
|
|
The present study was performed to examine the possible anti-inflammatory effects of a herbal drug ASCH in RAW264.7 cell line. Inflammation was induced by LPS toxin treatment to RAW264.7 macrophage cell line. Increases in cytokine production such as IL-1β, IL-6. and IL-18, COX-2, NOS-Ⅱ (iNOS), and TNF-alpha were observed at mRNA level in the LPS-treated RAW264.7 cells. Measurement of IL-6, nitric oxide and the reactive oxygen species (ROS) showed increased production of these inflammation mediators. Treatment of ASCH effectively decreased IL-1β protein in a dose-dependent manner, and IL-6 and IL-18 were reduced at 100㎍/㎖ of ASCH concentration. NO production was also decreased by ASCH treatment. A slight inhibition for TNF-alpha in terms of protein, but not mRNA level was obtained by 100㎍/㎖ of ASCH treatment. ASCH treatment to normal RAW264.7 cells did not produce any cytotoxicity, indicting that the action of ASCH was selective to inflammatory cells. Thus, the present data suggest that ASCH may act as an important regulator to alleviate the inflammatory symptoms.
