Hyla savignyi (Anura: Hylidae) Derisi Üzerine Histolojik Bir Çalışma

Abstract

Deri önemli bir savunma hattıdır ve dış çevre ile iletişim kuran ve temasta olan bir organdır. Mevcut çalışma Hyla savignyi derisinin histomorfolojik karakterlerinin değerlendirilmesi için planlandı. H. savignyi dorsal ve ventral derileri tıpkı diğer omurgalılarda olduğu gibi çok katlı yassı epitel ve dermisten oluştu. Dermis, süngerimsi dermis ve kompakt dermisten oluştu. Hem dorsal hem de ventral deri örneklerinde iki tip dermal bez (granüler, mukoz bezler) tespit edildi. Granüler bezlerin lümeni güçlü asidofilik reaksiyon veren salgı granülleri ile doluydu. Mukoz bezler mukositler ile kaplıydı ve mukoz bezlerin belirgin bir lümeni vardı. Derinin histomorfolojik özellikleri bireysel varyasyon göstermedi.

A Histological Study on the Skin of Hyla savignyi (Anura: Hylidae)

Abstract

Integument is a prominent defense line and is one of the organs for communication and contact with the external environment. The current study was designed to assess the histomorphological characteristics of the skin of Hyla savignyi. The ventral and dorsal skins of H. savignyi were composed of a stratified squamous epithelium and dermis like that of any other vertebrate. The dermis was made up of spongious dermis and compact dermis. In both ventral and dorsal integument samples, two types of cutaneous glands (granular, mucous) were identified. The lumen of granular glands was filled with secretory granules that showed strong acidophilic reaction. Mucous glands were lined by mucocytes and had an obvious lumen. Histomorphological characteristics of the skin did not show any individual variation.
