    Abstract:
    The effect of selenium deficiency on the chronic toxicity of adriamycin was examined in rats fed diets adequate in vitamin E. Selenium-deficient and selenium-supplemented diets were fed to rats for 10 wk, after which groups of 10 rats fed each diet were given weekly intravenous injections of adriamycin in saline at doses of 0, 0.5 or 1.0 mg/kg body weight for 12 wk. All rats were killed at 24 wk. Even though the cardiac glutathione peroxidase activity in the selenium-deficient group was less than 1% of that of the selenium-supplemented group, the severity of the adriamycin-induced cardiomyopathy was similar in both groups. However, the selenium-deficient rats were more sensitive to the growth-inhibiting effect of the higher dose of adriamycin than the selenium-supplemented rats. Moreover, the lower dose of adriamycin caused a mild nephropathy in 70% of the deficient rats but affected only 10% of the supplemented rats. Selenium status may have to be considered when adriamycin is used as a chemotherapeutic agent.
