title: [Prospidin-C14 blood level, distribution in the organs and tissues and excretion from the body of rats].
abstract: Experiments were conducted on rats with sarcoma-45 and intact ones to study the prospidin-C14 content in the blood, distribution of the drug among the organs and tissues and its elimination from the organism. A single intravenous introduction of prospidin-C14 was found to be followed by its quick (in 2 hours) disappearance frob the blood. During the first 15 minutes the distribution of the drug over the organs and tissues was of a non-uniform nature and different from the distribution of other known antineoplastic agents, with relatively high concentrations of prospidin-C14 being demonstrable in the kidneys, lungs, the skin, intestine, bones, pancreas and low ones--in the liver, spleen and lymph nodes. The elimination of the drug from the organs and tissues is non-uniform. Prospidin-C14 and labeled products of its transformation are quickly (during the first 24 hours after administration) passed from the organism, chiefly with urine.
