Article

The aim of this study was to report some of the morphological characteristics of the kidney involved in urine concentration and hence water conservation in the dromedaries. A total of 20 fresh kidneys of 10 apparently healthy camels were used in this study. The architecture of the renal pelvis was revealed by dissection and polyvinyl chloride corro...

The aim of the study was to provide values for morphometric parameters of histological components of normally delivered full term placentas of Sudanese women and compare them with reported parameters for other ethnic groups. A total of 200 histological sections, stained with hematoxylin and eosin and trichrome stains were used to give a final sampl...

Respiratory Function in Birds, Adult and Embryonic Satellite Symposium of the 27th International Congress of Physiological Sciences, Paris 1977, held at the Max-Planck-Institute for Experimental Medicine, Göttingen (FRG), July 28–30, 1977 Editors: Piiper, Johannes (Hrsg.) • A. S. King, • D. Zoe King, • M. A. Abdalla Summary The walls of the smal...
Article
Full-text available
The nephrotoxicity of low-dose methotrexate (MTX) and the rescue effect of leucovorin were studied by electron-microscopic examination of the kidney of guinea pigs. One group received MTX as a single weekly dose of 10 mg/kg, i.p.; a second group received a similar dose divided into three equal fractions. The third group received MTX rescued with an...
Article
Full-text available
The poll glands of the camel are tubuloalveolar glands. They consist of lobules separated by interlobular connective tissue. Adrenergic axons and blood vessels including fenestrated capillaries are present in the intralobular connective tissue in close proximity to the secretory cells. The prominent features of the secretory cell cytoplasm are many...
Article
The neurotoxicity of single and divided low-dose methotrexate (MTX) and the rescue effect of leucovorin (folic acid) were investigated by light and electron microscopic examination of the cerebellum of Guinea pigs. One group of animals received a single weekly intraperitoneal MTX in a dose of 10 mg/kg, a second received a similar dose divided into...

The adrenal gland of the camel consists of an outer cortex and an inner medulla. The general disposition of the cortex and medulla, however, differs occasionally from that of other mammals. Extensions of medulla could reach as far as the periphery of the cortex. Islet of medullary tissue may be found in sections of the cortex and cortical tissue co...
Article
One hundred and fifty goats were diagnosed as having proven gangrenous mastitis. The disease was categorized into early, intermediate and late stages. Gangrenous mastitis in goats is typified by a sudden onset, dark hyperemia, and edema with progressive discoloration of the distal part of the udder. The disease affected lactating goats but not the...
Article
The extramural aortico-pulmonary bodies of the domestic fowl were analysed in electron micrographs by point-counting morphometry. The Type I cell constituted about 34% of the total volume of the parenchyma, whereas the supporting cells (Type II cells, pericytes and Schwann cells) constituted about 26%. The blood capillaries occupied the lowest volu...
Article
Full-text available
The lungs of 5 domestic fowls have been analysed electron microscopically by standard morphometric methods. The anatomical diffusing capacity has been calculated from the relevant parameters. The blood-gas barrier consisted essentially of endothelium, basal lamina, and a very thin squamous epithelial cell. Granular cells are absent and interstitial...
Article
The lungs of 107 birds of 19 different species from seven orders were fixed in situ. The mean volumes of both fixed lungs together ranged from 0.15 to 95.31 cm3. Histological sections of one lung from each bird were analyzed by point counting with a Zeiss integrating eyepiece to determine the volume densities and thence the absolute volumes of the...
Article
Morphometric analysis of the kidney of the camel was carried out on gross slices and histological sections using standard morphometric methods. The renal cortex occupied about 50% by volume of the kidney, and the ratio of the thickness of the medulla to that of the cortex was about 4:1. The relative thickness of the medulla was about 7.89. This par...
Article
The bronchial arteries arose from the oesophagotracheobronchial branches of the common carotid arteries. In the goose, duck, Muscovy duck, and turkey several small bronchial arteries supplied the whole length of each primary bronchus, including the orifices of the secondary bronchi. In the guinea-fowl and quail similar bronchial arteries supplied o...

Article
A search for pulmonary arteriovenous anastomoses was made in 15 adult domestic fowls using Lycopodium spores and microspheres. The diameter of the spores and microspheres ranged from about 10 to 33 mum. To dilate any pulmonary arteriovenous anastomoses, the birds were warmed to induce panting, killed with chloroform, or injected intravenously with...
Article
The bronchial circulation was studied in 25 adult domestic fowls. The right and left bronchial arteries originated caudal to the syrinx from a bronchoesophageal artery which is a branch of the right common carotid artery. Each bronchial artery ramified on the wall of the extrapulmonary part of the corresponding primary bronchus and finally anastomo...

The architecture of the pulmonary circulation in the domestic fowl was studied in 30 birds of different breeds by injection techniques and serial sections. The branches of the cranial, caudomedial and caudolateral rami of the pulmonary artery form interparabronchial arteries which are essentially transverse to the long axis of the parabronchi. At t...
