摘要: 本文报告25例人体两型包虫增殖生长的组织学变化,其中肝、肺囊型包虫病15例,另10例为肝泡型包虫病。这两型包虫均具有外殖性和内殖性芽生的两种增殖方式.囊型包虫内殖性芽生显示为生发膜局限性增生、育囊形成、和原头节发育,外殖性芽生主要表现在原头节通过角质层和纤维外囊到达外囊外边的迁徙过程。泡型包虫内殖性芽生的特点是泡囊壁向囊腔内增殖和形成隔膜,外殖性芽生显示泡囊壁向泡囊外增殖,产生子泡囊和孙泡囊等。

Abstract: This paper reports the histologic changes in the proliferation and growth of two echinococcus types in 25 patients, 15 with liver or lung cystic echinococcosis and 10 with liver alveolar echinococcosis. The results indicated that these two echinococcus types shared two modes of proliferation including exogenous and endogenous budding. In cystic echinococcus type, endogenous budding showed localized hyperplasia of the germinal membrane, the formation of the brood capsule, and the development of the protoscolices. Exogenous budding appeared chiefly in the migratory process of the protoscolices from the germinal membrane to the outside of the exocyst passing through the laminated layer and the fibro-exocystic wall (Figs. 1-4). In alveolar echinococcus type, endogenous budding was characterized by the propagation of the alveolar wall towards the intra-alveolar cavity with the formation of septum. Exogenous budding showed the alveolar wall propagated towards the exterior to produce daughter and grand-daughter alveoli (Figs. 5-7).
