Neutrophil infiltrations in sections of dermis. a Pathological changes were examined microscopically (hematoxylin and eosin staining, ×400), Green triangle pointing to infiltration cells. b HO-1 expression was detected by immunohistochemical staining (×200), Blue triangle pointing to HO-1 positive cells. Tg: Transgenic goat, Wt: wild type. The results are expressed as the means ± SEM. * P < 0.05 in Tg versus Wt groups
