    Abstract:
    The i.p. or i.v. injection of frog virus 3 (FV3) in mice produces a hepatitis which leads to the death of the animals within 24 h. This hepatitis is of a purely toxic nature since the virus does not develop at 37 degrees C. The toxic effect of the virus, which can be differentiated from the infectious effect, involves one or more structural proteins. The first pathological changes occur during the first few hours after the injection in the vicinity of the nuclei of the liver parenchyma cells in the form of changes in the chromatin and nucleoplasm. The inhibition of the synthesis of cellular macromolecules and of the function of nuclear enzymes points to the fact that it is the nucleus that is first and foremost attacked. Necrosis and biochemical disturbances in the vicinity of the cytoplasm appear later on. Premedication of the mice with a water-soluble silymarin salt leads to a distinct rise in the survival rate of the animals. The protective function of silymarin is dependent on the dose and on the duration of the premedication. The LD50 of FV3 in those mice which had previously been given silymarin, is approximately three times that of the animals which received no premedication.
