title: [Electron miscroscopic liver changes in acute carbon tetrachloride poisoning in man)].
abstract: Lesions of the liver revealed by light and electron microscopy at two young men, workers of the chemical industry are described. At one of the patients biopsy was performed twice at the other three times. Patient having jaundice were admitted to hospital because of the suspected acute viral hepatitis. Laboratory findings have shown an acute parenchymal lesion. By light microscopy at one of them mid-zonal, at the other centro-lobular necrosis of hepatic cells further lipoid droplets of the cytoplasma of hepatocytes were revealed. Electronmicroscopically in the first biopsy specimens, and at one of the ptients at the second biopsy as well mostly damage to the mitochondria (enormous osmiophilia of the matrix, presence of osmiophil granules) and enlargement of the tubules of the endoplasmic reticulum could be seen. The controll clinical and morphological findings evidenced the reversible character of the process. Authors stress the differences existing between hepatic lesions caused by CCl4 at different persons on one side, and at rat and human liver on the other.
