文摘This paper is to report the pathological changes of canine renal tissuesin the period of 48h after severe steam inhalation burns.All the specimens from84 male mongrel dogs were observed with light microscopy,and 30 out of the 84with electron microscopy additionally.The morphological changes of the glomeriwere characterized by hypertrophy and/or hyperplasia,and retrogressive changesof glomerular cells.The former manifested itself as cell enlargement and an in-crease of the amount of cytoplasm and of the number or organelles.The latterwas evidenced as intracellular edema.The renal tubules showed a varying degreeof degeneration,necrosis,and cast formation.Tubular necrosis affected more fre-quently the proximal convoluted tubules,of which the etiological factors were dis-cussed briefly.
