“…Our microscope findings confirm the dominance of mucous cells in the zygomatic and molar glands of the ferret in agreement with earlier observations by P odarr & J acob (17, 18) in this species and with those in the cat (9, 19) and the dog (10, 19). The findings of a zygomatic gland weight close to that of the parotid gland, and of zygomatic glands and molar glands weighing more than the sublingual glands suggest a significant contribution from these glands to the total response of mucin‐rich saliva secreted in the ferret under natural circumstances.…”

“…There was also a small number of thin cells at the periphery of the acini that stained intensely with PAS but not with Alcian blue. These cells probably correspond to the ‘cap cells’ described in the canine and feline zygomatic gland (9, 10). Additional thin cells at the periphery of the acini that were unstained with both PAS and Alcian blue were presumably myoepithelial cells.…”

Parasympathomimetics or cholinesterase inhibitors taken orally may relieve dry-mouth symptoms, but this route of administration is often associated with adverse systemic reactions. In the present study, an animal model was worked out aimed at stimulating the submucosal glands and avoiding systemic effects. In the anesthetized ferret, saliva from the parotid, sublingual and submandibular glands was prevented from reaching the mouth. Vehicle or physostigmine was applied topically for 10 min on the buccal and labial mucosa on one side, while the other side served as a control. Fluid from each side was collected every 5 min Mean basal secretion was 0.17 mg 5 min(-1). The response to physostigmine 0.1% did not exceed that of the vehicle. At higher concentrations the responses lasted 80-120 min. Peak secretion was nine (0.25% physostigmine), 13 (0.5% physostigmine) and 40 (1% physostigmine) times higher than baseline. At 1% physostigmine, the secretion from the control side was elevated, and a small flow from the duct-cannulated parotid gland occurred, indicating systemic effects. Arterial blood pressure was well maintained. Additional observations on the duct-cannulated zygomatic gland showed that secretion from this gland increased already within the 10-min period of application of physostigmine to the overlying mucosa. The distance between the mucosa and the zygomatic gland was only about 1 mm. Physostigmine-induced secretion was abolished by atropine. Local gland stimulation may be an attractive alternative for the treatment of dry mouth.

Goblet cells in the intestine of shi drum Umbrina cirrosa showed the presence of glycoconjugates particularly rich in fucose and N-acetylglucosamine residues. They displayed also sialic acid linked to galactosyl( 1<3)N-acetylgalactosamine and to galactosyl( 1<4)Nacetylglucosamine. All the nine horseradish peroxidase-conjugated lectins employed with the only exception of GSA II marked the enterocytes supranuclear region and the cell coat; the cell coat showed a more intense reactivity toward the different lectins, particularly enhanced with the use of fucosyl specific lectins.

Background The African painted dog is classified as a relic canid lineage, inhabiting areas south of the Sahara. The fennec fox is the smallest member of the Canidae family, found in the Arabian Peninsula and northern Sahara. Methods The gross anatomy and light microscopic examination of the oral cavity glands were studied in five adult captive South African painted dogs and five adult captive fennec foxes from the Wroclaw Zoological Garden, Poland. In this research, the zygomatic gland, monostomatic sublingual gland, polystomatic sublingual gland, mandibular gland, and parotid gland were examined for their topography, morphometry, histology, and histochemistry using hematoxylin and eosin, azan trichrome, mucicarmine, PAS, AB pH 1.0, AB pH 2.5, AB pH 2.5 PAS, and HID. Results We found that the parotid glands were consistently the largest, followed by the mandibular and sublingual glands (both monostomatic and polystomatic). The zygomatic gland was the smallest in both South African painted dogs and fennec foxes. Interestingly, there were noticeable differences in the size, shape, and even composition of the secretory products between the two species. The zygomatic and polystomatic sublingual glands in the South African painted dog and the fennec fox were complex branched tubular. In the South African painted dog, the monostomatic gland was a branched tubular compound gland, while in the fennec fox, it was a branched tubuloalveolar compound gland. The mandibular gland in hunting dogs was a branched tubular compound gland, while in the fennec fox a branched tubuloalveolar compound gland. The parotid gland in the fennec fox was a branched acinar compound gland, whereas in the painted dog was a branched tubuloacinar. Conclusions The basic structure of their glands is similar to that of other terrestrial carnivores, indicating a shared evolutionary origin and function. However, differences in the composition of their secretory products can reflect adaptations to their specific diets. This research provides valuable insights for veterinary medicine and underscores the importance of further studies. By analyzing wild canid populations and including a broader range of species with diverse diets, we could gain a deeper understanding of how diet influences salivary gland morphology within the Canidae.
