Figure 4. Effects of A) ASHMI; B) Lingzhi; C) Kushen; and D) Gancao on eotaxin-1 production by human lung fibroblasts.
Human lung fibroblasts were cultured with or without herbal extracts for 48 h. Eotaxin-1 level in the culture supernatants was measured by enzyme-linked immunosorbent assay. The percentage of inhibition was calculated with respect to untreated cells. Three replicates were run at each concentration. Concentration-response curves were constructed using Prism 4.0 (GraphPad Software, San Diego, CA, USA). The dotted lines indicate the 95% confidence intervals.
