作者对西伯利亚西部后睾吸虫病地方性高发区的托波尔斯克地区自1950年至1987年的尸检材料作了回顾性分析。全部资料分为3个时期,第1期(1950～1954年),居民的组成及生态环境相对稳定;第2期(1966～1975年),由于石油天然气的开发,居民人数猛增,流动增加;第3期(1983～1987年),向都市化发展,生态环境发生变化。以肝脏和胆囊的扩大,肝与膈肌的粘连,肝内或肝外胆管的扩张及硬化判定后睾吸虫病的感染程度。胆道腔中有少数虫体的低度感染,胆道多数区段由虫体形成“虫栓”的中
The authors performed a retrospective review of the autopsy material from 1950 to 1987 in the region of Topolstok, a endemic area of the genital tuberculosis in western Siberia. All data are divided into three periods, the first period (1950 ~ 1954), the composition of residents and the ecological environment is relatively stable; the second period (1966 ~ 1975), due to the development of oil and gas, the number of residents soared, the flow increased ; The third period (1983 ~ 1987), the development of urbanization, the ecological environment changes. With liver and gallbladder expansion, the adhesion of the liver and diaphragm, intrahepatic or extrahepatic bile duct dilatation and hardening determine the incidence of testicular infection. Biliary tract in a small number of low-level infection of parasites, the majority of the biliary tract by the body to form a “worm bolt” in
