Figure 5. Effects of CE-CKC 0.005% emulsion and emulsion excipients (CKC Em and Tylo Em) on IL-6 and IL-8 secretion inhibition following lipopolysaccharide (LPS) stimulation in HCE-2 cells. Results are expressed as mean ± standard error of the mean (SEM) of percentage of inhibition versus LPS-stimulated cells. *, p<0.05; **, p<0.01; ***, p<0.001. Tylo, tyloxapol. Experiment were performed in triplicates.
