Popis: | Liver tissues from 17 patients with advanced stages of beta-thal/Hb E disease were examined by light and electron microscopy, with emphasis on cellular damage due to excess iron overload. Various histochemical stains were performed to grade degrees of iron deposition and fibrosis, and to demonstrate hepatitis B surface antigen, in Kupffer cells as well as macrophages. The results of light and electron microscopic studies were correlated. There was a variation in the distribution of hepatic iron and the severity of fibrosis. In most of the cases ballooning degeneration of the hepatocytes, increase in number of lysosomes, hemosiderin and ferritin in hepatocytes as well as in the sinusoidal lining cells were found. The ferro-acidophilic body, representing another important form of hepatocellular necrosis also occurred. So far no precise mechanisms can be concluded. |
