ovine pulmonary adenocarcinoma (opa) was studied in the lungs of 15 naturally-affected sheep (9 with classical and 6 atypical lesions) by transmission electron microscopy. two lung samples from normal sheep were used to develop the ultrastructural criteria. pathologic lesions consisted of focal-multifocal to coalescent nodules or masses in the cranioventral or diaphragmatic lobes. ultrastructur...

ovine pulmonary adenocarcinoma (opa) is a contagious and transmissible lung cancer of sheepresembling human bronchiolo-alveolar carcinoma. in the present study, lungs of 9400 sheep slaughtered infars province, iran were examined morphopathologically. the opa was diagnosed in the lungs of 21(0.22%) out of 9400 sheep. frequency of involvement of different lobes in the affected lungs was includeda...

Aneurysm of the pulmonary artery is a rare condition in animals, and to our knowledge it has never been reported association with neoplasia. This report describes case an adult female sheep “Churra Galega Bragançana” breed aneurysm associated lung cancer (ovine adenocarcinoma).

概要 In vivoで 肺血管外水分量(pulmonary extravascular water volume, PEV)を測 定す るこ とは,1954年Chinard & Ennsに よ り示唆 されて以来,基 礎的検討がか さね られ臨床への応用が可 能 となつた.本 論文 は,Ramseyら の方法 に準 じて後天性 心疾患に おけ るPEVを 測定 し,肺 循環諸 量,臨 床経過 お よび血液 ガス値 との関連について検 討 した ものである。測定時 の肺血管内圧 とPEV とは,粗 な正相 関(r=0.48,P<0.02)を 示 すにす ぎず,む しろPEVは 左心不全の既往 と関連 が あ る とい う結果 をえた.す なわ ち測定時 の肺 血管 内圧は同 じレベ ルにあ りなが ら,左 心不 全既往のあ る例は,既 往 のない例 に比ベ てPEVは 著 明な増加を示...

A mathematical model is used to study the dynamics of ovine brucellosis when transmitted directly from infected individual, through contact with a contaminated environment or vertically through mother to child. The model developed by Aïnseba et al. [A model for ovine brucellosis incorporating direct and indirect transmission, J. Biol. Dyn. 4 (2010), pp. 2-11. Available at http://www.math.u-bord...

The effects of endogenous and synthetic glucocorticoids on fetal lung maturation are well-established, although the role of leptin in lung development before birth is unclear. This study examined mRNA and protein levels of the signalling long-form leptin receptor (Ob-Rb) in fetal ovine lungs towards term, and after experimental manipulation of glucocorticoid levels in utero by fetal cortisol in...

Background: No validated and standardized animal models of pulmonary air leakage (PAL) exist for testing aerostatic efficacy lung sealants. Lack negative control groups in published studies intrinsic sealing mechanisms healthy lungs might contribute to a translational gap, leading poor clinical results. This study aims address the impact on validity PAL models, investigate conditions required a...
