title: [Chemobiokinetics of sarcolysin and its peptides with glutaminic acid].
abstract: A 14C study of chemobiokinetics of sarcolysin and its peptides of glutaminic acid, dosage and routes of administration was conducted in intact rats and those bearing Walker's carcinoma. Similar in shape for peptides, kinetic curves differed from those found for sarcolysin. The rates of absorption and excretion of sarcolysin peptides in intraperitoneal and, particularly, oral administration were lower than those of sarcolysin. Tumor appeared to play a role in a higher rate of peptide excretion. While sarcolysin and its peptides distribution in organs and tissues was generally identical, time of peak radioactive concentration build-up was different. Time needed for accumulation and excretion of peptides from tumor was much longer than from other organs or tissues. Sarcolysin went chiefly to urine while peptides--to faeces.
