【摘要】 对3例肺细粒棘球绦虫病病人肺内取出的棘球蚴进行了电镜观察,扫描电镜观察结果:棘球蚴胚层腔面和角皮层外侧面有大小不一、呈圆形、椭圆形的囊泡,其上复盖着粗细不等的细丝。在胚层腔面间隔一定的距离,见边缘整齐的裂隙状凹陷。透射电镜观察结果:棘球蚴胚层细胞腔面有许多长而粗、呈指状、排列整齐的微绒毛,微绒毛为四层膜性结构。微绒毛下的致密带内见许多小泡、微管和少量微丝。胞质内见许多线粒体、粗面内质网、游离核蛋白体、少量糖原、高尔基体和平滑肌。并见两种不同形态组织结构的原生质体。对上述观察结果的生物学意义进行了讨论。更多还原

【Abstract】 The ultrastructure of hydatid cysts extirpated from the lungs of three cases with E. granulosus infection was observed and illustrated by scanning and transmission electron microscopy. SEM showed that vesicles were different in size and shape, either round or elliptic, covered with thin and thick filaments on the germinal layer and on the lateral side of the laminated layer. Regular-edged, crack-shaped pits were found at different distances on the germinal layer. TEM showed numerous long and thick microvilli arranged regularly on the germinal layer. Each microvillus appears to be a four-layered membraneous structure. A number of vesicles and microtubules with less filaments are seen in the compact band beneath the microvilli. Within the cytoplasm there are prominent mitochondria, rough endoplasmic reticulum, ribosomes, Golgi bodies, smooth muscle and two kinds of protoplasts of different morphological structures.更多还原
