[Effect of liposome-encapsulated pentacin on plutonium-239 excretion]

A study was made of the influence of pentacin, encapsulated in liposomes, on the excretion of monomeric plutonium-239 from dogs and albino rats. Pentacin in a liposomal form, in comparison with free pentacin, increased the excretion of plutonium in urine from a dog body by 23.5% when administered in 24 h, and by 28% when administered in 20 days; in rats, the excretion increase made 40% after the administration in 30 or 45 days.
