【摘要】 目的:了解小鼠感染華支睪吸蟲后肝臟的病理變化,為研究華支睪吸蟲的致病機制提供參考依據。方法:胃蛋白酶消化法獲取華支睪吸蟲囊蚴,人工灌胃法感染小鼠,采用病理學方法取材、固定及染色,觀察小鼠肝臟的病理學變化。結果:不同感染時間的炎癥反應程度存在差異,出現纖維組織增生、膽管壁增厚、嗜酸性囊腫等病理學現象。結論:小鼠感染華支睪吸蟲后肝臟出現了顯著的病理學改變,這種現象對于研究人體內華支睪吸蟲的致病作用具有一定的參考價值。
【關鍵詞】 華支睪吸蟲; 囊蚴; 病理變化
Pathological Observation of Liver in Mice Infected with Clonorchis Sinensis/PAN Yu,RONG Wei,LI Zhi-hui,et al.//Medical Innovation of China,2017,14(30):015-018
【Abstract】 Objective:To investigate the pathological changes of liver in mice infected with clonorchis sinensis,and to provide the scientific basis for the study of pathogenicity of clonorchis sinensis.Method:The pepsin digestion method was used to obtain metacercaria of clonorchis sinensis,the artificial gastric irrigation was used to infect mouse,the liver tissues were taken from the mice after infection for pathological examination,the procedure included the fixed of body,paraffin section and staining,observed the pathologic changes by microscope.Result:There were differences in the degree of inflammatory reaction at different infection times,pathological changes such as fibrous tissue hyperplasia,eosinophilic cyst,the walls of hepatic bile ducts had thickened and so on.Conclusion:After the mice infected with clonorchis sinensis,the liver showed a remarkable pathological change,and this phenomenon have a certain reference value for the study of the pathogenic role of clonorchis sinensis in human body.
【Key words】 Clonorchis sinensis; Metacercaria; Pathological change

華支睪吸蟲病(Clonorchiasis sinensis)俗稱肝吸蟲病,是一種重要的食源性寄生蟲病,可引起多種肝臟及膽管系統并發癥。WHO國際癌癥研究署明確膽管細胞癌的致癌物包括華支睪吸蟲,成為了全球被忽視的熱帶病之一,給感染者造成明顯的生命質量損失,成為影響食品安全和人民健康的重要因素之一[1-3]。中國作為華支睪吸蟲病負擔最為嚴重的國家和感染的高發國家之一[4-6],需要加強相關研究工作。本研究觀察小鼠感染華支睪吸蟲后肝臟的病理變化,為研究華支睪吸蟲的致病機制提供參考依據,現報道如下。
