Morphology of the Spleen in the Camel's Fetus (Camelus dromedarius): Gross Anatomy, Histology and Scanning Electron Microscopic Studies

The spleen is essential for immunological responses to infections that are carried in the blood. The study aimed to investigate the gross anatomy, topography, histology and scanning electron microscopy of the spleen in the dromedary camel fetus (Camelus dromedarius). Fifteen camel foetuses aged 87–418 days were used to examine the prenatal development of the spleen. Standard anatomical, histological, and scanning electron microscopy procedures were applied. Anatomically, the spleen was situated medially to the ribs, caudally to the stomach, and on the caudolateral side of the abdominal cavity. It had C-shaped surfaces with rough surfaces and serrated edges. In the first and second trimesters, the spleen was dark brown and grayish in the third trimester. Histologically, the capsule was made of very thin mesenchyme connective tissue, and the parenchyma had a sporadic distribution of many cell types in the first trimester. The capsule displayed thick, dense, irregular connective tissue with descending trabeculae made up of collagen fibers and bundles of smooth muscle fibres in the second and third trimesters. The parenchyma in the second and third trimesters was presented as white and red pulps. Megakaryocytes were detected in all samples. Scanning electron microscopy revealed that the spleen is lined with mesothelial cells separated by reticular connective tissue fibers. The reticular cells in the cordal gaps, marginal zones, and parietal sheath were relatively small in the first trimester of gestation. In the second and third trimesters, the reticular cells formed a network where dendritic macrophages and lymphoblasts were present …

Effect of thermal manipulation during embryogenesis on gene expression of myogenic upstream activation factors pre-and post-hatch in broilers

A total of 1,440 fertile eggs were divided randomly and equally into 5 treatment groups; control (no TM) and 4 treatment groups: TM1, TM2, TM3, and TM4 that were thermally subjected to 39 C for 18 h with 65% relative humidity daily, during embryonic days ED 7–11, ED 11–15, ED 15–18 and ED 7–18, respectively. Out of TM conditions that were investigated, TM1 resulted in a significant improvement in expression of myogenic factor-5 (Myf5), myoblast determination protein (MyoD) and myogenin (MyoG) in pre and post hatch broiler muscle when compared to the control. This study aimed to determine the optimum time for thermal manipulation during embryogenesis that may result in improvement in expression of myogenic regulatory factors (MRFs): Myf5, MyoD, MyoG and myostatin (MSTN) in broiler muscle. Thus, the results of this research may provide a means of improvement of myogenesis of pectoral and thigh muscles of broilers proceeding from early embryogenesis (ED7) through post-hatch day.

Molecular investigations of the effect of thermal manipulation during embryogenesis on muscle heat shock protein 70 and thermotolerance in broiler chickens

The objective of this study was to elucidate the optimum protocol timing of thermal manipulation (TM) during embryogenesis, which underline genetic improvement of muscle thermotolerance acquisition. For the present study, 1,440 fertile eggs were divided randomly and equally into control (37.8 °C with 56% relative humidity) and four thermally manipulated groups (TM1, TM2, TM3, and TM4) subjected to 39 °C for 18 h with 65% relative humidity daily during different embryonic periods. Then, at day 35 post-hatch, all groups were subjected to thermal challenge at 43 °C for 6 h to identify the level of thermotolerance acquisition differences between them. Hsp70 mRNA expression was evaluated by using a relative quantitatively RT-qPCR. Single nucleotide polymorphisms sequence of the Hsp70 gene was evaluated by Sanger's sequencing method. Pectoral and thigh muscles samples were subjected to immunohistochemistry to detect Hsp70. Among TM conditions that were investigated, TM1 (39 °C for 18 h during embryonic days (ED) 7–11) induced a significant improvement in thermotolerance parameters (body temperature and T3 levels) during thermal challenge combined with an increase in the levels of Hsp70 mRNA and its protein with a high stability of nucleotide sequences in both pectoral and thigh muscles. The partial DNA sequence of Hsp70 gene in TM1 was reported, and nucleotide sequences were deposited in NCBI GenBank database with the accession numbers (MK852579) and (MK852580). Thigh muscle thermotolerance acquisition was higher than pectoral muscle during thermal challenge at 43 °C for 6 h. Thus, TM during ED7 …

Light and Electron Microscopy of Buccal Salivary Glands of the Dromedary Camel

The study was aimed to investigate the light and electron microscopic structure of buccal salivary glands in the dromedary (Camelus dromedarius). Anatomically, the dromedary camel buccal glands were well-developed and were located on the lateral side of the cheek. Three parts (groups) of the buccal glands could be observed: dorsal, middle and ventral parts. Histologically, the secretory units were tubule-acinar, surrounded by myo-epithelial cells and supported by connective tissue. Whereas, the dorsal glands were purely mucous and the ventral glands were purely serous in secretion, the middle ones were muco-serous with predominant mucous cells. Ultra-structurally, the glandular cells of the serous secretory units (type I cells) contained numerous microvilli, many electron-dense secretory granules, abundant rough endoplasmic reticulum and mitochondria. On the other hand, the mucous-secreting cells (type …

Spatial Expression of Osteopontin in Testis, Epididymis and Spermatozoa in Dromedary Camel

The aim of this study is to clarify the function of osteopontin (OPN) through its expression and localisation in male testis, epididymis and sperm cell of dromedary camel during rutting season. Testis and epididymis parts (caput, corpus and cauda) specimens were obtained from 8 mature male camels and semen was collected from 4 another fertile camels for sperms. OPN mRNA expression and its location was analysed using quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) techniques, respectively. OPN mRNA expression was significantly (P < 0.05) higher in the cauda of epididymis than other epididymal parts and testis. Immunolocalisation revealed high immunoreaction intensity in the elongated spermatids in seminiferous tubules and Leydig cells in interstitial tissue. However, a faint immunostaining was seen in spermatogonia and Sertoli cells. Along the epididymis …

Effect of Momordica charantia on Insulin Immune-reactive Pancreatic Beta Cells and Blood Glucose Levels in Streptozotocin-induced Diabetic Rats.

The present study was conducted to determine the antidiabetic effect of Momordica charantia on pancreatic islets of Langerhans in streptozotocin-induced diabetic male Wistar rats in relation to the distribution of insulin immuno-positive beta cells. Momordica charantia was fed to rats at 2%, 5% and 10% of the standard diet for 12 w. After sacrifice, the pancreatic tissues were obtained for histopathological and immunohistochemical observations. In addition, monitoring of fasting blood glucose was applied each month during experimental period. The results revealed that the oral doses of Momordica charantia at 5% and 10% of the daily diet increased the percentage of insulin-positive pancreatic beta cells as well as the size and number of pancreatic islets. Moreover, significant (p= 0.01) dose and time-dependent reduction in fasting blood glucose levels were observed. In conclusion, these results suggest that …
