AbstractIn the present study, the parotoid region, dorsal and ventral integuments of Lyciasalamandra billae and Lyciasalamandra luschani basoglui were investigated in terms of localization of hyaluronic acid (HA) and histochemical characteristics. HA immunoreactivity was carried out using biotinylated hyaluronic acid binding protein (B-HABP) labelled with streptavidin-fluorescein isothiocyanate (FITC). HA was mainly localized in the stratum spongiosum of L. billae and L. luschani basoglui for water homeostasis and skin functionality. Light microscopic observations revealed that the dorsal and ventral integuments of L. billae and L. luschani basoglui exhibited basic morphological characteristics of other amphibians: the epidermis was composed of a stratified squamous epithelium and the dermis subdivided into stratum spongiosum and stratum compactum. Two different types of dermal glands (mucous and granular glands) were identified in the spongious dermis of the dorsal and ventral integuments whereas in the parotoid region, three different types of glands (mucous, granular and parotoid glands) were examined.

The digestive tracts of 44 specimens of Schizodon knerii were studied using anatomical, histological and histochemical techniques. The mouth has terminal position, the lip epithelium is squamous stratified with mucous, claviform cells and taste buds, teeth have an incisive form and the tongue has a stratified squamous epithelium with mucous cells and taste buds. The oropharynx cavity is formed by gill apparatus and pharyngeal teeth. The oesophagus presented pleated mucosa, a stratified squamous epithelium with mucous cells, oesophageal glands and taste buds. The stomach presented cardiac, fundic and pyloric regions, simple prismatic epithelium with tubular glands, with none in the pyloric region. The intestine contains 11-15 pyloric caeca, a simple prismatic epithelium with brush border, goblet cells and lymphocytes. Mucosal cells, oesophageal glands and goblet cells reacted positively to PAS, amylase + PAS, Ab pH 2.5 and Ab pH 0.5. Gastric prismatic cells reacted positively to PAS, amylase + PAS, but only those in the pyloric region reacted positively to Ab pH 2.5 and Ab pH 0.5. The results improve the understanding of the anatomy of S. knerii feeding habits and the presence of mucosubstances in the epithelium, highlights the importance of glycoproteins for passing food through the digestive tract.
