Влияние Пептидов На Постлучевое Восстановление Гемопоэза

In the work we investigated the possibility of reducing the harmful effects of ionizing radiation on the hematopoietic system of mice with linear and cyclic peptides of low molecular weight. The results showed that after double intraperitoneal injections of the peptides to irradiated mice (4 Gy) practically complete regeneration of cellularity of bone marrow and spleen observed on the eighth day. Signs of accelerated hematopoietic regeneration in the peripheral blood (reticulocytosis) were also observed. The positive effect of the peptides by criteria of cellularity of the bone marrow and spleen was seen in animals got higher dose (6 Gy), however, it was poorer, as compared with the effect observed in mice with dose of 4 Gy.
