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.

Keywords
