人体细粒棘球蚴接种小鼠体早期发育观察

人体肺或肝内棘球蚴的生发囊或原头蚴接种杂交小白鼠腹腔,最初可见游离的原头蚴周围有大量中性细胞及少数嗜酸性细胞,原头蚴结构模糊,生发囊外有明显的细胞反应带。如系存活的原头蚴其内部结构多集聚于一处,并有少数顶突钩,原头蚴可向不同方向形成有角质层外被的突起,突起可脱离原头蚴,形成有角质层的新个体,但未见内侧有生发层存在。

Observations on the Early Development of Hydatid Cysts in Mice

The paper reports the results of the early development of human soure brood capsules in the abdominal cavity of mice from different time of development. We suggested that 1). one protoscolex can developed into many new larval cysts by means of the exogenous proliferation, 2)the new formed exogenous cysts without a germinal layer, but how the laminated layer formed, so the histogenesis of the laminated layer will be reconsidered, 3) although it is a vigorous cysts surrounded by the fibrous tissue, many septa still can be formed inside of the cysts, but these cysts were not belong to the multiple type of hydatid cyst (alvolar cysts of E. multiocularis), and 4 ).causative factor of the secondery infection in human case after operation, it seems that need not very numerous protoscolecs spilled out from the cyst into the abdominal cavity, only just a few protoscoleces can develop into numerous cysts if there were enough space for their further growth.
