Attenuation of irritant-induced cytotoxicity by LR in Keraskin^TM. Tissues were pretreated with LR for every other day 4 times and SLS was treated for 10 min. (a) Tissue viability was determined by the WST-1 assay. Results are expressed by the fold of control viability as mean ± SE of independent more than three tests and analyzed by two-way ANOVA. * p < 0.05 compared with PBS-treated control. (b) H&E stained tissues after with PBS or SLS treatment were measured by the light microscopy.
