A doxorubicin-lecithin preparation was tested in vitro on B16 melanoma and Lewis lung carcinoma cells, and in vivo on C57BL/6 mice inoculated with 3LL cells. Results obtained demonstrated that the preparation possesses the same antitumor activity as doxorubicin. The cardiotoxicity of doxorubicin and of the doxorubicin-lecithin association were studied for 120 days after the end of the treatments in Wistar rats inoculated once a week for 5 weeks with equivalent doses of the drugs.

Abstract
A doxorubicin-lecithin preparation was tested in vitro on B16 melanoma and Lewis lung carcinoma cells, and in vivo on C57BL/6 mice inoculated with 3LL cells. Results obtained demonstrated that the preparation possesses the same antitumor activity as doxorubicin. The cardiotoxicity of doxorubicin and of the doxorubicin-lecithin association were studied for 120 days after the end of the treatments in Wistar rats inoculated once a week for 5 weeks with equivalent doses of the drugs. Myocardial lesions were observed in both the groups of animals, but their severity and extent were reduced in rats treated with the doxorubicin-lecithin association, and their onset was also delayed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
