Fig. 5From: An Ayurvedic herbal extract inhibits oral epithelial cell IL-8 responses to host and bacterial agonistsDifferential inhibition of agonist stimulated IL-8 by gingival keratinocytes. Fifty percent inhibitory dose (ID50) estimated from an experimentally derived dose-response curve for each concentration of Sudantha (SUD) against basal levels of IL-8 (SUD Control) and IL-8 induction by live F. nucleatum (MOI 1:500), IL-1, and TNF-α (both at 100 ng/ml) performed three independent times. Controls are cell culture medium with the indicated concentrations of SUD. Error bars represent standard error of meansBack to article page
