健康犬经多次少量感染血吸虫尾蚴后发展至结肠肉芽肿病变.取肉芽肿不同病变的上皮组织作透射电镜观察。结果认为结肠肉芽肿病变的上皮细胞超微结构变化符合血吸虫性增生性改变。
Healthy dogs were infected with Schistosoma japonicum cercariae after a small number of lesions developed to colon granuloma lesions were taken different lesions of granuloma epithelial tissue under transmission electron microscopy. The results suggest that epithelial ultrastructure changes in colonic granuloma lesions in line with Schistosoma proliferative changes.
