[Effect of gamma-interferon on hepatic granuloma formation in mice infected by cysticerci of Taenia saginata asiatica].

Immunohistochemical streptavidin biotin-peroxidase complex method was used to investigate the effect of gamma-interferon (IFN-gamma) on the hepatic granuloma formation and liver fibrosis in mice infected with Taenia saginata in Duyun area of Guizhou Province. The results reveal contrary relation between the level of IFN-gamma in the liver and the degree of liver fibrosis (p<0.01). The injection of IFN-gamma considerably decreased (p<0.01) the area and size of granuloma (p<0.01).
