Intermediate filaments belong to a large family of proteins which contribute to the formation of the cytoskeleton. The immunolocalization of cytoskeletal proteins has been used extensively in the diagnosis of various renal pathologies. The present study described the immunolocalization of the cytoskeletal proteins vimentin, desmin, smooth muscle ac...

Atrioventricular node (AVN) and Atrioventricular bundle (AVB) development in the camel heart was studied during the 1 st , 2 nd and 3 rd trimesters of gestation using histological techniques. Thirty hearts of camel foetuses were used in this study. Specimens were collected from Tamboul and Al-Salam slaughterhouses, Sudan. The samples were prepared...

Standard Stereological methods of the point-counting techniques were applied to study certain components of the camel foetus pancreas at different embryological stages (First trimester, Second trimester and Third trimester). The volume densities (Vv) of the acini, ducts, islets of Langerhans, connective tissue and blood vessels were determined and...

Basement membranes consist of various proteins, the major ones being laminin and collagen type IV. Primary defects in these two proteins have been extensively associated with kidney pathologies. This study aimed to establish baseline information on the immunohistochemical distribution of laminin and collagen type IV, and to corelate these with the...

ABTRACT. Ultrastructure of the dromedary camel heart was studied during the second and third trimesters of gestation (131-426 days). A total of 10 hearts were used to study the ultrastructural development in camel foetuses. Hearts were collected from Tamboul slaughterhouse, Gezira, Sudan, and then they routinely prepared for scanning and transmissi...

Kidneys from adult she camels, cows and ewes (eight from each) were investigated using histologic and histometric techniques to study the renal capsule. The capsule in the kidney of the three species was made up of two layers, outer and inner. The outer layer of the renal capsule was composed mainly of dense collagenous fibres arranged in wavy bund...

The development of the Purkinje fibre (PF) of the camel foetus was studied in dromedary camel foetuses during the three gestational periods. A total of 30 hearts were used, the hearts were collected from Tamboul and Al-Salam slaughterhouses, Sudan. The samples were prepared by routine histological procedures and stained by the general histologic...

The histology and ultrastructure of the different components of the juxtaglomerular apparatus (JGA) in the kidney of the dromedary camel (Camelus dromedarius) were described in the present study. Five samples selected randomly from the renal cortex of eight female adult dromedary camels were used for histology and ultrastructure. Results obtain...

The histological structure of the sinoatrial node (SAN) in the dromedary camel foetus was investigated using routine histological techniques and some special stains. Twenty foetuses were used. They were divided into two groups 10 foetuses were in the second trimester (131-260 days); the rest in the third trimester (261-423.5 days of gestation). Sam...

The distribution of immunoglobulin (Ig)-containing cells in the mammary gland of the goat was studied at different stages of the reproductive cycle using immunohistochemical techniques. Generally, Ig-containing plasma cells (IgA, IgG and IgM) in the mammary gland were abundant during pregnancy, increase in number after parturition and gradually dec...

Myocardial bridges (MBs) are cardiac abnormalities in which segments of coronary artery are embedded in myocardium. They are considered normal in adult dromedary camels. This study aimed to investigate the existence and morphology of foetal myocardial bridges in dromedary camels. 30foetuses obtained from Tambul and Al-Salam slaughterhouses, Sudan,...

Endocrine cells in the thymus of the one-humped camel (Camelus dromedarius) were studied using immunohistochemical methods. Serotonin, insulin, gastrin, glucagon, calcitonin, substance P, Pancreatic polypeptide (PPP)-, CCK, vasoactive intestinal peptide, galanin and somatostatin-cells were detected in the camel thymus by Avidin-Biotin-Complex techn...

Abstract Ultrastructural development of the camel heart was studied during the first trimester of gestation using transmission and scanning electron microscopy. Eight foetal hearts from the early and late stages of the first trimester (between 86 days and 128 days gestation) were collected and routinely prepared for electron microscopy. Scanning...

The aim of this study was to investigate the lipids and cardiac marker enzymes on the heart of the camel with myocardial bridges. Blood samples were takenfrom seven adult camels showing myocardial bridges. The samples were collected from Al-Buga´a slaughterhouse, Sudan. The samples were analyzed biochemically for two cardiac enzymes (cardiac mar...

IgG and IgM levels in colostrum, milk and serum were quantitated by radial immunodiffusion. Concentration of milk IgG was found to be 65 mg/ml at the colostrum period. It further decreased to 3 mg/ml after Day 15 of lactation. However, the concentration of serum IgG was constant throughout the reproductive cycle (8-11 mg/ml). Concentrations of IgM...

The objectives of this study were to investigate some histochemical components and to conduct morphometrical study on the liver of the camel. Ten livers of adult dromedary camels were used. The distribution of glycogen throughout the hepatic tissue has been studied with the use of either Best’s carmine, or Periodic Acid Schiff reagent (PAS). The gl...

The pinealocytes of the pineal gland of the young, middle age and old age camels were studied at light microscopic level. The pineal gland consisted of a wide, triangular, superficially localized distal part and a narrow, elongated proximal part, attachedvia the choroid plexus to the inter commissural region of the diencephalon. The accessory p...

Mammary glands of pregnant, lactating and resting goats were studied by immunohistochemistry for lymphocyte subpopulations using a panel of monoclonal antibodies. All T lymphocyte subpopulations that may have a role in the immune response, CD2+, CD4+, CD8+ and gamma delta T cells and subsets, were present in the mammary gland and were noted to incr...

The distribution of immunoglobulin (Ig)-containing plasma cells and T lymphocyte subpopulations in the mouse mammary gland was studied in different stages of the reproductive cycle using immunohistochemical techniques. Generally, Ig-containing plasma cells (IgA, IgG and IgM) in the mammary gland were few during pregnancy. They gradually increased i...
