[Characteristics of 57Co-bleomycetin accumulation in the primary tumor and in its metastases to the lungs in mice with Lewis carcinoma].

Distribution of 57Co-bleomycin was studied in mice with Lewis carcinoma implanted into different parts of the body. It was found that organ distribution of the labeled antibiotic did not depend on the tumor localization. The accumulation level of 57Co-bleomycin in Lewis carcinoma implanted subcutaneously into the pad foot was 3 times higher than that in the healthy pad.

[57Co-bleomycetin pharmacokinetics in the body of mice with LIO-1 lymphosarcoma].

Pharmacokinetics of 57Co-bleomycetin was studied on mice with lymphosarcoma LIO-1. It was found that at early periods of intravenous administration of the labeled antibiotic, i.e.
