Effect of ES on ear thickness in living P. acnes-injected mice ears. (a) The suppress effects with 1, 10 mg/ml of ES on P. acnes-induced ear edema in mice were evaluated by measuring the ear thickness. (b) Paraffin sections of Ear tissue were stained with H&E observed by microscope. Values represent mean ± S.E.M. (n = 5). Data were analyzed by Tukey post hoc test ( * p < 0.05 versus control and ** p < 0.05 versus P.acnes alone)
