초록
Wikyung-Tang(WKT) is herbal medication used in abcess-causing respiratory disease. Previous in vitro study demonstrates that WKY presents anti-proliferative effects in A549 cells. Here we show that WKY protects mice against lipopolysaccharide(LPS)-induced acute lung injury (ALI). We pretreated mice orally with WKY(2.34 and 5.85 g/㎏ body weight) 1, 24 and 48 hours before intratracheal administration of LPS. For same condition, control group was pretaken orally distilled water before LPS administration. 24 hours after LPS intratracheal instillation, bronchoalveolar lavege fluids(BALF) was obtained to measure protein and proinflammatory cytokines(TNF-α, IL-1β, IL-6). Protein and proinflammatory cytokines in BALF of WKT treated groups were totally decreased. Statistically, Protein, TNF-α and IL-1β of high concentrate WKT treated group decreased significantly compared with control group. In conclusion, WKY had some anti-inflammatory effect in a clinically relevant model of ALI. these results indicated that WKY was effective in inhibiting ALI and might act as a potential therapeutic reagent for treating ALI in the future..
