摘要:The administration of adriamycin to rates increased (P less than 0.01) the interval, measured in msec, of the electrocardiographic QRS traces in rats, and the magnitude of the increase was ca. 50%. The administration of coenzyme Q10 to such adriamycin-treated rats allowed "rescue" or restoration of a normal QRS complex after 7 days of administration of coenzyme Q10. The QRS complex then remained normalized during the subsequent period of 21-30 days, by which time the cumulative dose of adriamycin had reached 24 mg/kg. Also, the QRS interval was lower (P less than 0.01) on day 33 than it was for rats treated to the same day with adriamycin alone. Coenzyme Q10 offers promise of rescue from at least some of the cardiotoxicity occurring in adriamycin-treated cancer patients, probably by a similar mechanism to that of the clinical rescue from toxicity of methotrexate by a cofactor of folic acid (citrovorum factor).
