绦虫对人畜威胁极大,特别多房棘球蚴寄生在肝脏,类似肿瘤样的增殖分化。鉴于多胺与细胞的增殖分化有关,因此本文对绦虫后绦期的多胺代谢进行了如下观察。材料:实验用4种绦虫的后绦期:肥头绦虫(Taenia crassiceps)、水泡绦虫(T.hyda-tigena)、猫泡尾带绦虫(T.taeniae formis)和多房棘球绦虫(Echinococcus multilocula-ris)。多胺样品的制备:4种后绦期绦虫自感染动物中取出后,在0.25mol/L Tris缓冲液中匀浆,-80℃放置备用或立即用过氯酸 Tapeworm great threat to humans and animals, in particular, multi-room echinococcosis parasitic in the liver, similar to tumor-like proliferation and differentiation. Since polyamines are involved in the proliferation and differentiation of cells, the following observations were made on the polyamines metabolism after the tapeworm stage. MATERIALS: Post-smears of 4 species of test tapeworm: Taenia crassiceps, T. hyda-tigena, T. taeniae formis, and Echinococcus multilocula -ris). Preparation of polyamine samples: Four post-damp-stage tapeworms were removed from the infected animals, homogenized in 0.25 mol / L Tris buffer and stored at -80 ° C for either ready-to-use or immediate use of perchloric acid
