The effect of luteolin on LPS-induced hydrogen peroxide production, mast cell degranulation and intestinal microcirculation blood flow. a The effect of luteolin on LPS-induced hydrogen peroxide production. Pictures were captured at 400x magnification. Arrows: DHR fluorescence on the venular walls. b The effect of luteolin on LPS-induced mast cell degranulation. Pictures were captured at 400x magnification. Arrows: degranulated mast cell. c The effect of luteolin on LPS-stimulated intestinal microcirculation blood flow. All of the representative images of each group were presented with the respective quantification showing right correspondingly. All of the data were expressed as means ± SEM (n = 6). Significant differences were indicated by ^##P< 0.01 as compared with control group, ^*P< 0.05, ^**P< 0.01 as compared with LPS group
