肝毛细线虫(Capillaria hepatica)是野生鼠类及许多哺乳动物的常见奇生虫,实验动物中并不多见。本实验室一批日本大耳白兔18只,体重2.13～2.69kg。剖检发现57％感染了肝毛细线虫。本文简略报导感染兔肝脏的病理学改变及血清谷丙转氨酶(SGPTT)活性的变化。结果病理学改变: 感染兔肝脏表面可见1至数个黄豆大小的白色结节,质硬。镜下,结节内充满大量虫卵,形似鞭虫卵,但较大,平均大小为31×54μ,膜双层。虫卵的一端有嗜碱性染色的塞状物,为肝毛细线虫虫卵的主 Capillaria hepatica is a common monster of wild rodents and many mammalian species found in laboratory animals. A group of Japanese rabbits in this laboratory 18, weighing 2.13 ~ 2.69kg. An autopsy revealed 57% of infected liver cap worms. This article briefly reports the pathological changes in infected rabbit liver and serum alanine aminotransferase (SGPTT) activity changes. Results Pathological changes: 1 to several soybeans of white nodules were seen on the surface of infected rabbit liver, which were hard. Microscope, nodules filled with a large number of eggs, shaped like whip egg, but larger, with an average size of 31 × 54μ, double membrane. Eggs at one end of basophilic staining of the plug, for the host of liver capillary worm eggs
