title: Effect of actinomycin D-containing lipid vesicles on murine renal adenocarcinoma.
abstract: Forty Balb C/CR mice inoculated with renal cell adenocarcinoma were divided into five groups. Group A (seven animals) received phosphate buffered saline intraperitoneally; group B (seven animals) received free actinomycin D 300 microgram/kg IP; group C (nine animals) received lipid vesicles containing actinomycin D 300 microgram/kg IP; group D (eight animals) received a mixture of free actinomycin D 300 microgram/kg and empty lipid vesicles IP. The median survival of group A was 32 days, of group B 30 days, of group C 45.2 days, of group D 54 days, and of group E 42 days. It is suggested that giving the mixture of the drug and the lipid vesicles produces a balance similar to that found in a vesicle solution containing the actinomycin D. It is also suggested that liposomes slow the absorption of actinomycin D from the peritoneum.
