[Effects of prodigiozan on post-radiation recovery of hemopoietic precursor cells and colony-stimulating factor level in long-term cultures of mouse bone marrow].
Prodigiozan injected to long-term cultures of mouse bone marrow 24 h before irradiation increased CFUs and CFU-GM number and colony-stimulating factor (CSF) level by the time of delivery of ionizing radiation. As early as 60 min following irradiation of bone marrow structures with a dose of 2 Gy the number of CFUs and CFU-GM decreased considerably, and from day 3 on after irradiation the indices under study were gradually restored. By day 14 the cultures preinjected with prodigiozan exhibited higher recovery levels. The decrease in the number of precursor cells 60 min after irradiation was accompanied by a drastic increase in the CSF content of cultures; the CSF release in cultures protected with prodigiozan was more moderate than in the irradiated controls.
