Abstract

The effect of the synthetic PSMA peptide on dividing cells of laboratory animals was studied. The experiment was carried out on male white laboratory mice of the BALB/c-line. The toxic effect of PSMA peptidi was evaluated at therapeutic (1.4 μg / kg of animal weight or 0.04 μg / animal) and subtoxic (140 μg / kg of animal weight or 4.0 μg / animal) doses. The cytotoxic effect of PSMA peptide on red bone marrow cells and cambial intestinal cells of the of laboratory mice was determined. A decrease in the proliferative activity of the colon crypt cells was revealed upon administration of a subtoxic dose of the PSMA peptide and there were no signs of toxic damage to the red bone marrow cells of animals.
 Key words: toxicity, proliferation, synthetic peptides, mitotic index, micronucleus test.
