本文的观察结果表明:接种后1周,原头节的皮层内已有实质细胞长入,虫周有较大空隙,宿主细胞反应轻微。死亡原头节则已被大量炎细胞紧密包围;2～4周,大部分原头节的实质组织消失而形成细粒棘球蚴生发层,宿主细胞反应基本消失。而死虫周围则有夏科-雷登氏结晶体出现;2个月后,生发层外均已出现角质层,死亡崩解虫周的细胞反应开始减轻;4～6个月,细粒棘球蚴囊不断增大,并在生发层内陆续出现不育囊结构,虫周纤维组织较少,而解体的原头节内均已有大量胶原及网状纤维长入。对生发层的组织发生学以及适宜中间宿主对原头节的细胞反应特点进行了简要讨论。
The results of this study showed that: 1 week after inoculation, protoplasts had parenchyma cells growing in the cortex, with larger voids in the periplasm and less host cell reaction. The death of the original head has been surrounded by a large number of inflammatory cells; 2 to 4 weeks, most of the original head tissue disappeared to form echinococcus granulostris germinal layer, the host cell reaction disappeared. While the dead insects around the summer Branch - Radon crystals appear; after 2 months, the stratum corneum has been outside the germinal layer, the death of the collapse of the peritoneal cell cycle began to reduce the response; 4 to 6 months, Echinacea Cysts increased, and in the germinal layer in succession appeared sterile cyst structure, less peritubular fibrous tissue, while the disintegration of the original head section have a large number of collagen and reticular fibers grow into. Tissue genesis of the germinal layer and the characteristics of the cellular response of the intermediate host to the primordial head were briefly discussed.
