本文对犬重度呼吸道蒸汽烧伤48h内肾脏标本进行了组织学和超微结构观察,结果表明:复合组和单呼组病变基本相似。肾血管球细胞可表现两方面的变化:一是细胞肥大和/或增生,前者表现为细胞肿大,胞质增多,富含细胞器;二是细胞退变,主要为细胞内水肿。细胞内水肿,复合组较单呼组为多见。肾小管显示不同程度的变性、坏死及管型形成。小管坏死多累及近曲小管。文中对近曲小管坏死的发生因素进行了简要讨论。
In this paper, histological and ultrastructural observation of renal specimens within 48 hours after severe respiratory steam burn in dogs was performed. The results showed that the lesions in the composite group and the single call group were basically similar. Renal vascular cells can show two changes: First, cell hypertrophy and / or hyperplasia, the former showed cytoplasm, cytoplasm increased, rich organelles; the second is the degeneration of cells, mainly for intracellular edema. Intracellular edema, complex group is more common than the single call group. Tubules showed varying degrees of degeneration, necrosis and tubular formation. More tubule necrosis involving the proximal tubule. In this paper, the occurrence of proximal tubule necrosis was briefly discussed.
