Abstract

Abstract: In this study, elastic fibers and collagen fibers of normal sika deer and abnormal laxity on the nape of neck were observed by Weigert’s-Van Giesson staining and Masson staining for investigating the pathogenesis of cutis laxa in sika deer. The results showed that there were many elastic fibers in the control group arranged regularly dense, wavy, stained uniform in the reticular dermis；However, there were few elastic fibers perpendicular to the epidermis in the papillary dermis. Cuis laxa sika deer showed inelastic fibers in the papillary dermis (No. 0 and 79) or severe hypoplasia in the reticular dermis, appeared accumulation, breakage (No.33 and 79), disorganized, irregular shape (No.0). Collagen fibers of the normal deer were distributed multi-layered regularly in the dermis. Collagen bundles of collagen fibers in cutis laxa was markedly thick, reduced, arranged disorderly and severe sparse compared to the normal collagen fibers. It was exactly similar to the histology of cutis laxa skin in human.
