Abstract

We studied the morphologic appearance of alcoholic hyalin (AH)-containing hepatocytes in liver biopsies from 14 patients with alcoholic liver disease. Most hepatocytes had a characteristic appearance. The cells were swollen and hydropic with an intact cell membrane. The mitochondria had variable-sized cristae which were both shortened and elongated. The smooth endoplasmic reticulum was markedly decreased. The rough endoplasmic reticulum was bizarre, with detachment of the ribosomes that surrounded the AH. The hepatocytes that contained AH bodies had lost almost all the glucose-6-phosphate activity but had variable amounts of succinic dehydrogenase and diphosphopyridine nucleotide diaphorase activities. The neutrophils admixed with mononuclear cells attached themselves to the hepatocytes and then invaginated into the hepatocytic cytoplasm with focal lysis of the cell membrane mediated via the release of neutrophilic lysosomes. The distortion of protein-synthesizing organelles and decrease in glucose-6-phosphatase activity suggest that the AH-containing hepatocyte is metabolically decompensated. The final cell death may be related to the neutrophilic attack, rather than the metabolic derangement.

摘要

我们研究了14例酒精性肝病患者肝活检中含酒精性透明小体(AH)的肝细胞的形态学表现。大多数肝细胞具有特征性外观。细胞肿胀且呈水样变性,细胞膜完整。线粒体嵴大小不一,有缩短和伸长的情况。滑面内质网明显减少。粗面内质网形态怪异,围绕AH的核糖体脱离。含有AH小体的肝细胞几乎丧失了所有葡萄糖-6-磷酸酶活性,但琥珀酸脱氢酶和二磷酸吡啶核苷酸黄递酶活性各不相同。与单核细胞混合的中性粒细胞附着于肝细胞,然后通过嗜中性溶酶体的释放介导细胞膜局部溶解而内陷进入肝细胞胞质。蛋白质合成细胞器的变形和葡萄糖-6-磷酸酶活性的降低表明含AH的肝细胞代谢失代偿。最终的细胞死亡可能与嗜中性粒细胞攻击有关,而非代谢紊乱。
