Hydatid disease, caused by the parasite Echinococcus granulosus, mostly affects the liver and the lungs with hydatid cysts which consist of three layers: (1) the outer pericyst; (2) the middle laminated membrane; and (3) the inner germinal layer. Pericyst, as the outermost layer of the hydatid cyst, is made by host cells encasing the hydatid cyst. An extremely close interaction exists between this host tissue and the parasite, and any degenerative changes of the pericyst would result in hydatid cyst degeneration or rupture. The pericyst plays an undeniably important role in the development and survival of the hydatid cyst.
包虫病由寄生虫细粒棘球绦虫引起,主要影响肝脏和肺部,形成的包虫囊肿由三层组成:(1)外层的外囊;(2)中间的角皮层;(3)内层的生发层。外囊作为包虫囊肿的最外层,由包裹包虫囊肿的宿主细胞构成。这种宿主组织与寄生虫之间存在极其紧密的相互作用,外囊的任何退行性变化都会导致包虫囊肿退变或破裂。外囊在包虫囊肿的发育和存活中起着不可否认的重要作用。
