“…These authors did not highlight granular ducts in rabbit mandibular gland, nor segments of ducts with granular cells as previously mentioned authors. As opposed to these authors, we highlighted ducts with large numbers of granular cells, a situation comparable from many points of view to the one existent in animals which present four distinct segments for mandibular gland ducts: intercalated, granular, striated and excretory, as in gerbil (Bazan et al, 2001) …”

The present study focuses on the intralobular ducts present in rabbit mandibular gland, from a histological and histochemical point of view. We harvested mandibular gland samples from five healthy male rabbits (Oryctolagus cuniculus), acquired from a private breeder in Cluj county. Samples were paraffin embedded and subsequently stained for histological investigation with hematoxylin-eosin. PAS and Alcian blue reactions were used for histochemical assessment. Results show that mandibular gland in rabbit contains one type of acini, namely serous. Concerning the intralobular ducts, there were three types identified: intercalated, granular and striated. Granules present in the cytoplasm of the cells lining the granular ducts appear acidophilic on hematoxylin-eosin staining procedure. Histochemically, granular cells present a moderately PAS positive material (meaning they secrete neutral mucosubstances) and negative staining to Alcian blue reaction (no acid and sulfated mucosubstances were detected). We highlighted the presence of granular ducts in rabbit mandibular gland, which synthesize neutral mucosubstances according to the histochemical reactions applied.

“…The occurrence of well-developed serous cells may be an adaptation for raise digestion of carbohydrates in the oral cavity and also to increase production of antibacterial agent lysozyme to help reduce rate of infection establishment in the wild (29).The present study showed that myoepithelial cells surrounding the serous acini this finding was agreement with (30) while different with (31) the serous acini lack The myoepithelial cells surrounding the acini secretory end piece was provides contractile force to help move secretion from the acinicells and push them during the intercalated duct (32).The intercalated duct of simple cuboidal epithelium play important role in transport secretion from acini to striated duct, this simple cuboidal was reported by (22).The striated duct was lined by simple columnar epithelium it was transport secretion from the intercalated duct to the excretory duct,A tall cuboidal epithelium of striated duct was reported by (33), this result disagree with (34) reported that the intralobular duct in buffalo without striated duct.The interlobular duct was transport product to the oral cavity which was lined by stratified epithelium may reveal the need for protection of underlying basement membrane by occasional action of activated serous fluid enzyme (13).The distribution of goblet cells with epithelium of main duct play important role in modulation of saliva secret from acini by addition of mucous from goblet cells (8). The acini small in diameter and lumen this agreement with (8)In the histochemical study the parotid gland of buffalo show weak to moderate reaction with combined AB-PAS(PH 2.5)and in cow the acini show weak reaction,this result was confirmed by (8),(34) who mentioned that the secretions of the parotid gland contained neutral mucins and some sialo mucins.…”

The present work designed to describe the histological and histochemical features of parotid gland in buffaloes and cows.The glands were collected from ten heads of buffaloes and cows used. The histological and histochemical study revealed that the parotid gland in buffaloes and cows are compound tubuloacinar-type, having dense connective tissue capsule, the parenchyma consists of acini, intercalated, striated and excretory duct, acini surrounded by myoepithelial cells.The parotidis a purely serous gland. histochemical study,demonstrated of mucopolysaccharide by using combined AB-PAS, acini shows weak to moderate reaction in buffaloes but weak reaction in cows.

“…The ductal system of the major salivary gland (parotid, submandibular and submandibular) in the southern white‐breasted hedgehog from largest to smallest was as follows: excretory, striated and intercalated ducts like those found in the parotid gland of humans, rabbits and rodents (Al‐Saffar & Simawy, 2014; Amano et al, 2012; Harrison et al, 1987). While in the submandibular gland of some species including gerbils and rats, it was reported previously to have four types of ducts namely intercalary, granular, striated and excretory ducts (Bazan et al, 2001; Tsuboi et al, 2004). Interestingly, Tandler (1986) reported no striated duct in the retrolingual salivary gland of the European hedgehog.…”

This study aimed to investigate the major salivary glands in the southern whitebreasted hedgehog (Erinaceus concolor) histologically and histochemically. Five adult males were included in this study. The results showed that anatomically the shape of the parotid, submandibular and sublingual glands of the Erinaceus concolor was respectively almost pear, elliptical to pyramidal and oval. Histologically, the parotid gland had serous acini and secretory cells showed negative reaction to alcian blue (AB) (pH = 2.5) and negative response to aldehyde fuchsin (AF), methylene blue (MB) and PAS stains. The submandibular gland was a mixed gland of mucous and serous acini.The mucous acini were strongly positive for PAS, AB, MB and AF. However, serous acini were week for PAS and negative against AB, MB and AF stains. The sublingual gland was purely composed of mucous acini. The mucous acini of the sublingual gland were strongly positives for PAS, AB and MB methods. While their reaction to the AF staining was negative. In conclusion, the histological and histochemical observations of the major salivary glands of the southern white-breasted hedgehog (E. concolor) indicated that these glands shown similarities and some special different histochemical features as compared to other mammalian species.
