  • Title: [Mechanism of the pro-oxidant activity of tetracycline].
    Author: Oleĭnik AN, Ovsiannikova LM.
    Journal: Antibiotiki; 1983 Nov; 28(11):845-8. PubMed ID: 6316840.
    Abstract:
    It was shown on male rats that like ethanol tetracycline increased lipid peroxidation (LPO) in the hepatocyte membranes, evident from increased levels of diene conjugates and malone dialdehyde in the liver homogenates, especially on their combination. The signal amplitude of the EPR-forms of cytochrome P-450 and Cu-, Mo- and Fe-containing proteins did not change, while the content of the EPR-forms of the free radicals increased. High efficiency of antioxidants, such as tocopherol acetate, sodium selenite and tincture of Astragalus L. is indirect evidence of the role of the free radicals in initiation of LPO in tetracycline affections of the liver.
