Method By HE staining,pathological tissues of main organs of C. semilaevis Gunther with abdominal dropsy were observed. Result According to the results of histopathological observation,C. semilaevis Gunther with abdominal dropsy exhibited a large amount of ascites in the abdominal cavity;small intestinal mucosal epithelial cells were denatured and necrotic,and shed into the enteric cavity,with submucosal vascular congestion; the liver and pancreas tissues were denatured and necrotic,and the morphology of most liver cells disappeared. However,there was no remarkable pathological change in the heart,spleen and other organs.
