Abstract
The present work was undertaken to study the histopathological changes in the liver of rat Rattus norvegicus (Berkenhout, 1769) infected with Hymenolepis diminuta (Rud. 1819) larvae. Histopathological sections of infected liver were prepared by fixing small pieces of liver in buffer formalin for 24 h. The fixed material was dehydrated and prepared for block making by the usual procedure. Eosin and Hematoxylin stained serial section were mounted permanently in DPX. Sections were examined in detail and photomicrographs of selected section were taken by Nikon (Aptiphot-2) photomicroscope using Fuji Color Film. Histopathological study of selected portions of the liver revealed that H. diminuta larvae severely affected the whole morphology of the liver cells. Pronounced changes included pyknosis, necrosis, hypertrophy, hyperplasia and dislocation of liver tissue. Eosinophil aggregation along with caseous necrosis was obvious.
