对169例经临床和病理证实的慢活肝患者,进行了肝活组织光镜和电镜的回顾性探讨,从组织学及超微结构方面研究桥形坏死(BN)的类型及其发生机理,认为C-C 型BN 常是因微循环障碍所致;P-P 型BN 则为碎屑坏死病变(PN)的融合,此型BN 也易于稳定;而C-P 型BN 常为进展性病变,易向肝硬化发展。本文为临床治疗慢活肝提供了病理组织学依据。 A retrospective study was carried out on 169 liver biopsy specimens of slow-living liver confirmed by histopathology and histopathology. The histopathological and ultrastructural studies on the types and pathogenesis of post-mortem necrosis (BN) CC type BN is often due to microcirculation caused by; PP-type BN is debris fusion necrosis (PN), this type of BN is also easy to stabilize; and CP BN is often a progressive disease, easy to develop cirrhosis of the liver . This article provides a histopathological basis for the clinical treatment of slow-living liver.
