摘要

研究了日本血吸虫血吸虫体超微结构与小鼠中性粒细胞体外作用的关系。在抗体和补体存在的情况下,被许多中性粒细胞覆盖的血吸虫皮在孵育1小时内开始出现损伤。部分嗜中性粒细胞附着的寄生虫被皮颗粒胞质脱落,肌层解体,内部组织空泡化。然而,大多数细胞较少的血吸虫直到16小时仍保持其完整性。与小鼠中性粒细胞孵育1和2小时的血吸虫细胞化学检查清楚地表明,过氧化物酶活性在细胞和寄生虫表面的定位。

Ultrastructural observations on damage to schistosomula of Schistosoma japonicum by mouse neutrophils in vitro.

Ultrastructure of schistosomula of Schistosoma japonicum was studied in relation to the effect of mouse neutrophils in vitro. In the presence of antibody and complement, damage to the schistosomular tegument covered with many neutrophils began to appear within 1 h incubation. Exfoliation of the granular cytoplasm of the tegument, disorganization of the muscle layers and vacuolation in the inner tissues were seen in a part of neutrophil-attached parasites by 2 h incubation. However, the majority of schistosomula with fewer cells retained their integrity till 16 h. The cytochemical examination of schistosomula incubated with mouse neutrophils for 1 and 2 h demonstrated clearly the localization of the peroxidase activity on the surfaces of the cells and the parasites.
