| Abstract: | AIM: To make preparation of adriamycin 1ipo-somes conjugated with MDP and to study its anti-tumor ef-fects on Sprague-Dawley rat osteosarooma tumor model invivo. METHoDS= Liposome was prepared by improved re-verse-phase evaporation and conjugation of MDP and encap-sulation of adriamycin was done by transmembrane PH gradi-ent methods. Anti-tumor effects on Spragu-Dawley rats ofosteosarcoma tumor model in vivo were evaluated. RE-SULTS= The average encapsulation rate of adriamycin was92. 3% and conjugation rate of MDP 7O%, with the size of(15O I 35 ) nm in mean diameter by extrusion. Comparedwith that of adriamycin (ADM), the anti-tumor action of 1i-posomal adriamycin conjugated with MDP (MDP~LADM )was significantly enhanced (P |
