[Pathogenetic mechanisms of liver damage by the anthelmintic preparation chloxyl]

The pathogenetic mechanisms of hepatotoxicity of an anthelminthic drug chloxyl as compared with the mechanisms of CCl4 hepatotoxicity were studied on the basis of the change of the liver content of the primary (conjugated dienes) and secondary (malondialdehyde) products of lipid peroxidation. the activity of alanine aminotransferase and aspartate aminotransferase in the blood serum of rats and on the basis of the change of the liver structure. The pathogenetic mechanisms of chloxyl hepatotoxicity are close to those of CCl4 and consist in the activation of membrane lipid peroxidation, that is, an increase of the liver contents of the primary and secondary products of lipid peroxidation, an impairment of permeability of membranes of hepatocytes and their destruction with the release in the blood of cytoplasmic enzymes of alanine aminotransferase and aspartate aminotransferase.
