title: An increase of serum lipids after cumulative doses of doxorubicin and epirubicin in experimental animals.
abstract: A wide range of pharmacological actions has been attributed to the anthracyclins. In this study we examined their effect on serum lipids in experimental animals in parallel with histological alterations. Three Wistar rat groups were injected with doxorubicin, epirubicin or normal saline once a week for 12 weeks. Total serum lipids, cholesterol, triglycerides, HDL-cholesterol, transaminases, proteins and alkaline phosphatase were assayed weekly. A proportion of the animals were sacrificed at the same time points and the cardiac muscle, large vessels, liver and abdominal muscle were stained and examined under light microscopy. Serum lipids were found to increase gradually, starting after 8 weeks of drug administration, until the end of the experiment. Tissue damage was noted in the cardiac muscle, abdominal muscle and large vessels, also following an increasing trend. Doxorubicin had a more pronounced effect than epirubicin on both serum lipid increase and tissue destruction. These alterations may contribute to anthracyclin-related cardiac damage.
