Abstract

Global demand for the water monitor’s skin, Varanus salvator, has made it a valuable wildlife commodity. Leathercraft manufacturing must consider not only beauty but also the strength and flexibility of the leather, which is determined by its structure in the skin. Therefore, this study analyzed and evaluated the fiber type characteristic of the water monitor’s skin. Skin samples were collected from 10 Sumatra water monitors with a Snout-Vent Length size of 39-89 cm and were divided into small (39-59 cm) and large (60-89 cm) groups. The skins from the dorsocervical, lumbosacral, and ventral regions were proceeded for histological sections. Histochemical approaches utilized were Hematoxylin Eosin, Picrosirius Red, and Elastin Verhoeff’s Hematoxylin staining methods. Thick fibers are the main component in the skin, ranging from 69-73%, respectively, while thin fibers varied greatly and were observed predominantly in the reticular dermis. Fiber size in the reticular dermis of small lizards was lower than that of larger ones. Elastic fibers were observed abundantly at the border of the reticular dermis and subcutaneous layer in both small and large lizards. Moreover, the skin of the small-sized lizard also has a lower morphometric than that of a large-sized lizard, both in thickness and fiber type percentage. Therefore, the skin of small-sized lizards was considered less tough than that of large-sized lizards.

Abstract

This study was conducted to investigate the histological characteristic, type, and distribution of connective tissue in Sunda porcupine skin. The investigation was carried out in three adult of sunda porcupines at microscopic level using hematoxylin eosin, Masson thrichrome, Verhoeffs van Gieson, alcian blue pH 2.5 and periodic acid Schiff staining methods. Skin consists of epidermis, dermis hypodermis, and subcutaneous muscle. Quill follicles were the main and dominant structure as well as the specific characteristic on Sunda porcupine skin. The connective tissue was distributed well in basal membrane, dermis, quill follicle, and hypodermis with various intensity and density. The collagen was the main fiber found in the skin while the elastin fiber was not observed. The acid carbohydrate was found distributed well in the skin while the neutral carbohydrate was not detected in this study. In addition the fibers of connective tissue associated with the adipose tissue which found plentifully in quill follicles and hypodermis. The present results showed that the wide distribution of connective tissue might have an important role on the wound healing physiology of Sunda porcupine skin.
