| Popis: | Recombinant human interleukine-1beta (betaleukune) of Institute of especially pure biopreparation production had been examined as a treatment means at acute radiation disease of severe degree at dogs. Dogs were irradiated totally in doses above the LD95/45. Betaleukine had been administered s/c twice in day in 15 min - 2 h after irradiation. All the dogs, including control ones, received in acute period 8-24/26 days after irradiation antibiotics ampicillin and gentamycin i/m. Betaleukine increased 45 day-survival by 37% at 4 Gy and by 25% at 4.4 Gy. The effect correlated with more high level of nadir and more early beginning the leucocyte number restoration. We observed the regularity at all the dogs that received betaleukine as survived as died, but in the latter case in a lesser degree certainly. Besides the noticed character of leucocytes kinetics had been repeated at all the blood cell types but in the different degree. It had been concluded on the base of these observations that betaleukine acts on hemopoietic stem cells preferentially. The effect is in preventing death of a stem cells part, or in stimulating survived stem cells proliferation, or in both together. Betaleukin can be regarded as a suitable means of urgent pathogenic therapy at radiation accidents. |
