“…Also, the PAS‐positive reaction has shown that vicinal diol contains mucins mixed other mucins. These results correspond to that of earlier authors (Suprasert and Fujioka, 1987; Srisai et al., 2002). In contrast to Kum (2002), we did not define an apparent decrease in the reaction when PAS‐diastase staining method was applied to determine the presence of glycogen.…”

“…In this study, the PAS‐positive reaction revealed the presence of neutral, sialidase‐labile sialomucins and weakly sulphated acid mucins in the secretory units and excretory duct cells of the cervical and thoracic parts of the oesophagus in all age groups (Bancroft and Cook, 1984). This observation was similar to that reported for oesophageal glands in the chicken (Suprasert and Fujioka, 1987; Shibata et al., 1991). Also, the PAS‐positive reaction has shown that vicinal diol contains mucins mixed other mucins.…”

“…In contrast to Kum (2002), we did not define an apparent decrease in the reaction when PAS‐diastase staining method was applied to determine the presence of glycogen. These result indicated that the oesophageal gland of the quail did not contain the glycogen similar to that of the chicken (Suprasert and Fujioka, 1987; Shibata et al., 1991) and Germain’s swiftlet (Srisai et al., 2002).…”

“…Several studies have been carried out regarding the structure of the oesophagus and histochemistry of mucins in the oesophageal submucosal glands of humans and many other species (Hopwood et al., 1977, 1986; Jamdar and Ema, 1982; Henk et al., 1986; Long and Orlando, 1999; Poorkhalkali et al., 1999); on the contrary the histochemical studies on birds are very scarce (Suprasert and Fujioka, 1987; Gheri et al., 1988; Shibata et al., 1991; Shyla et al., 1991; Kum, 2002; Srisai et al., 2002). It is known that the organization of the tissues reflects their function–that of oesophagus in lubricating the food and transporting ingested food from the oropharynx to the stomach (Reece, 1997; Whittow, 2000).…”

In the oesophagus, mucins, which originate from oesophageal submucosal glands, play an important role in the mucosal protection as a pre-epithelial barrier. In this study, the structure of cervical and thoracic parts of oesophagus of Japanese quail during the post-hatching period was compared, and the contents of carbohydrate and gastric mucin MUC5AC of the oesophageal glands in these parts were analysed at the light microscope levels by applying conventional histochemical and immunohistochemical methods. The oesophageal glands were present at hatching, located in the laminae propria. The numbers of glands were different in the cervical and thoracic parts, but the differences were found to be insignificant. The thoracic part has the oesophageal tonsils which are associated with the glands. Oesophageal tonsil was formed from day 5 after hatching. In quail of all ages, the secretory epithelium of glands contained neutral sialomucins and weakly sulphomucins. The cells in the neck region of secretory units contained sialomucins, while the cells of excretory ducts had strongly sulphomucins. Sialomucin containing cells in the secretory units increased with the advance of age and glandular development. But, in the secretory units, the sulphomucin content of glands was more in the thoracic part. The secretory epithelium of tonsil-associated glands contained mostly sulphomucins and a little sialomucin. From the hatching, MUC5AC mucin was detected in the cells of excretory ducts. Although the lymphoepithelium of the tonsil units exhibited negative reactions to all histochemical methods, it showed positive reaction to MUC5AC mucin antibody. In conclusion, the cervical and thoracic parts may be functionally different and the thoracic part of oesophagus was transformed into an immunological organ following day 5 after hatching.

“…Meanwhile, the MG of the ALG and the PLG contained both neutral and acid mucin. However, these results seem similar to that founded in chicken [17] and in red jungle fowl [6]. The results of current study showed different reactions with alcian blue stain when the PH changed indicating that the LG contained weak acid mucin, and the MG and the PLG had strong acid mucin with the carboxylated and sulphated groups.…”

Common myna tongue was studied histomorphologically and histochemically. Four tongues of adult birds were carried out macroscopically and microscopically. The tongue was triangular; the dorsum of the body had median groove. Two to three backward directed papillae were located on each side of the body-base junction. A single transverse row of pharyngeal papillae was located behind the laryngeal cleft. The parakeratinized mucosa covered the entire surface of the tongue except clearly keratinized band on the ventrolateral surface and the conical papillae. Compared with the lateral group (LG), the secretory cells of the medial group (MG) of the anterior lingual glands (ALG) and the posterior lingual glands (PLG) contained large amount of mucin. It was neutral mucin. However, the LG had weak acid mucin with carboxylated group. Meanwhile, the MG of the ALG and the PLG had strong acid mucin with both carboxylated and sulphated groups. In conclusion, the morphological observation of the common myna tongue showed some variation from the other birds. Histochemical results indicated the differences between the LG and MG of the anterior lingual glands. However, no difference was observed between the latter and the PLG.
