Phenazepame exhibited properties of prooxidant in a model system of oleic acid methyl ester oxidation. After single intraperitoneal administration of phenazepame (5 mg/kg) the antioxidative activity (AOA) of rat liver lipids was decreased, correlating with level of histidase and urokinase activity in blood plasma indicating the liver tissue injury. Distinct alterations in the relative content of liver phospholipids were also noted. A phase type of alterations was observed in the content of these phospholipids as well as in the ratio phosphatidyl choline/phosphatidyl ethanolamine; at the same time, the phospholipid ratio was altered simultaneously with the alterations of the enzymatic activities in blood. After administration of the antioxidant, which normalized the AOA level and the phospholipid composition, activities of histidase and urokinase were markedly decreased in blood. The neuroleptanalgetic drug thalamonale, protecting liver tissue against the impairments, normalized the AOA level and the phospholipid composition. Thus, alterations in AOA and in the phospholipid composition reflected distinctly the unfavourable effect of phenazepame as well as the protecting action of thalamonale on liver tissue.
