| Abstract:: |
| Objective To investigate the capacity of bone marrow colony forming unit fibroblasts (CFU F) from mice with combined radiation burn injury. Methods Mice were treated with 5.0 Gy γ-ray radiation alone, 15% total body surface area (TBSA) Ⅲ° burn alone or combined radiation burn.The numbers of CFU-Fs were assayed by Dexter′s method. Results The numbers of CFU-Fs from mice with radiation and combined radiation burn injury were significantly decreased,compared with those of controls and mice with burn injury alone ( P <0.05-0.01). Conclusion The results reveal that the repairing process of bone marrow stromal cells from mice with radiation injury and combined radiation-burn injury is slow,and the combined radiation-burn injury inflicted on the stromal cells possesses the characteristic of radiation injury. |
