Ultrastructural changes in pulmonary oedema produced experimentally with ammonium sulphate

Pulmonary ultrastructural changes in hypoxic rats

“…oxygen. The development of both interstitial oedema and vesicles in endothelial cells have been described in the majority of reports of experimentally produced pulmonary oedema (Finegold, 1967;Hayes and Shiga, 1970;Meyrick, Miller and Reid, 1972;Colgrave and Creasy, 1975). Cottrell et al found only interstitial oedema with no endothelial cell damage when the oedema was produced by experimentally raising the left atrial pressure.…”

Hamsterlerde Deneysel Leptospi̇rosis'te (L. Grjppotyphosa) Akci̇ğer Kanamalarinin Işik Ve Elektron Mi̇kroskopi̇k İncelenmesi̇

“…Aynı bozukluklara çeşitli bakteriyel toksinlerin etkisinde, ammonium sulphate ve alpha-napthyl thiourea ile şekillenen akciğer ödeminde ve daha birçok şartlarda da rastlanmıştır (2,8,10,12,16,17,26,27,31,33). Leptaspirosis'te şekil-lenen kanarnaları bir kısım araştırıcılar etkenle ilişkili bulmuşlar ve kanamanın görüldüğü devrede akciğerde leptospira'ların da yoğun olduğunu kaydetmişlerdir (6, 38).…”

Ultrastructural changes in rat lung arterioles in conditions of altered permeability

“…In light-microscopic observations, these permeability changes in venules and arterioles were described by one of us (Bohm, 1966 and1973) as leakage of carbon through the endothelial layer, but other investigators (Hayes and Shiga, 1970;Cunningham and Hurley, 1972) thought that the tracer remained in the lumen of these vessels and adhered to the endothelium. The present electronmicroscopic studies and those made by Machado (1975) in pulmonary oedema induced by ANTU and ammonium sulphate, suggest that although leakage of carbon may be found (see fig.…”
