“…Areas of aggregation of adipose cells were also observed in this layer. Sultan et al (2023) observed the presence of melanin in the connective tissue of the serosa layer . Morpho-histological study of the proventriculus CONCLUSIONS The current study investigated the histological structures of the proventriculus of Circus aeruginosus (Linnaeus, 1766), the findings show that the proventriculus represents the upper stomach, the proventricular ventricular isthmus is not present so that the two organs form one large conical shape with a thick wall, and it has a number of well-developed longitudinal folds that reach to five longitudinal folds.…”

The study aimed to describe the anatomical, histological, and histochemical structure of the proventriculuc of adult male Eurasian marsh harrier, Circus aeruginosus (Linnaeus, 1766) (Accipitriformes, Accipitridae). Six birds were used for this study. The histological sections of proventriculus were stained with hematoxylin and eosin, periodic acid Schiff, and alcain blue. The proventriculus, representing the upper stomach, appeared as a conical structure with a thick wall connecting the caudal end of the thoracic esophagus to the gizzard. It had a light brown color. Microscopic examination revealed that the proventriculus wall consists of the outer tunica serosa, the tunica muscularis, tunica sub mucosa, and the inner tunica mucosa. The mucous layer exhibited folds, and the sulci represented many longitudinal folds with uniform lengths on its luminal surface. A single layer of columnar cells with oval-shaped nuclei made up the lining epithelium. The second layer was the laminal layer propria, composed of a relatively dense network of connective tissue. A thin, discontinuous layer of circularly arranged smooth muscle fibers in the muscularis mucosa separates the lamina propria from the sub mucosa. The submucosa appears as a very thick layer of dense vascular connective tissue, sub-mucosal compound tubuloalveolar glands form the major bulk of this tunica. These glands are arranged in one to three series of lobules that appear in different shapes. Muscularis externa consists of smooth muscle fibers arranged in a thick inner circular layer and a thin discontinuous outer longitudinal layer. The tunica serosa was a well-developed layer constituted by loose connective tissue covered by a single layer of flattened epithelial cells of the mesothelium. The proventriculus has some similarities to other bird species as well as some variations to other species, which may be explained by its nourishing food and behavior.

Background: The current study determined the histological alterations of the kidney and duodenum due to the administration of the cumin plant. The objective of the study was how consuming cumin affects the histological structure of the kidney and duodenum. Methods: Ten healthy male rabbits were divided into two groups of five each. They were housed in the animal facility at the College of Veterinary Medicine, Kerbala University. The treatment group received an oral dose of cumin extract at 250 mg/kg body weight once daily for six weeks, while the control group was given a standard diet and water. Hematoxylin and eosin staining was used to examine tissue samples from the kidneys and duodenum. Results: The histological analysis revealed significant changes in the kidney and duodenum tissues of the rabbits treated with cumin extract. In the kidneys, there was an increase in the diameter of glomeruli and a narrower lumen of the proximal tubules, indicating increased activity. Similarly, the duodenum of the treated group exhibited taller villi and deeper crypts, suggesting enhanced absorption activity. Moreover, the arrangement of tall columnar epithelial cells in the duodenal villi was altered. Conclusion: In conclusion, high intake of cumin extract showed various histological alterations in the urinary and digestive systems, particularly in the kidney and duodenum. These findings provided insights into the potential effects of cumin consumption on organ structure and function, highlighting the need for further research to understand its implications for human health better.

“…The specimens of the trachea, bronchi, and lungs were directly collected immediately after the birds were euthanized. These collected samples were then fixed in a 10% formalin solution (at a ratio of 1:10) for a period of 48 hours [35][36][37]. Following the fixation process, the tissue underwent preparation for histological analysis.…”

BackgroundThis study focused on the major components of mucus, known as mucins, within the mucosal epithelium of the respiratory system in Iraqi Common Quail. Six quail were utilized in accordance with animal ethics guidelines from the College of Veterinary Medicine at the University of Al-Qadisiyah. Histological analysis, utilizing H&E staining, aimed to identify key respiratory system structures. PAS plus Alcian blue stains were employed to identify specific carbohydrates in the trachea, bronchi, and lungs. RT-qPCR was used to assess the gene expression levels of MUC1 and MUC4.ResultsThe trachea and bronchi encompassed four distinct layers: tunica mucosa, tunica submucosa, hyaline cartilage, and tunica adventitia. The mucosa consisted of pseudostratified epithelium that transitioned into simple columnar cells toward the primary and secondary bronchioles. This transition further progressed into simple cuboidal and squamous epithelium at smaller tertiary branches of the secondary bronchioles. Notably, the bronchial tunica submucosa was thinner than the trachea. While hyaline cartilage was prominently present in the trachea, it became fragmented in the bronchi and diminished towards the lungs and secondary bronchioles. Lung tissue was characterized by numerous lobules housing alveoli connected to alveolar ducts and sacs, alongside an intricate network of blood vessels. The respiratory tissues, including the trachea, bronchi, and lungs, exhibited a strong affinity for PAS-combined Alcian blue stains. This confirmed the substantial presence of both acidic and neutral mucins within the epithelial cells and glands. The trachea demonstrated significantly elevated levels of acidic mucins and a concentrated amount? of neutral mucins. Transcriptome analysis indicated the expression of both MUC1 and MUC4 genes. Importantly, MUC4 expression surpassed that of MUC1 in the trachea, bronchi, and lungs.ConclusionThis study highlights the similarity of histological structures in the trachea, bronchi, and lungs of quail to typical avian species. Moreover, it underscored the substantial presence of both acidic and neutral mucins, with MUC4 being the predominant mucin, potentially playing a pivotal role in regulating mucosal barrier functions and interacting with pathogens. Nonetheless, further investigation is warranted to elucidate MUC4’s role in respiratory epithelial cells.
