Acquired radioresistance after low dose X-irradiation in mice.
Low doses (2.5-15 cGy) of X-irradiation two months prior to a second exposure to a sublethal dose enhanced the survival rate in mice. Optimal and significant increase was observed with 5-10 cGy. Endogenous spleen colony counts (endo-CFUs) after 7 Gy increased by a factor of about 1.7 in mice pre-irradiated with 5-10 cGy, while the number of blood forming stem cells (CFUs) in the pre-irradiated ...
متن کاملReduction of background mutations by low-dose X irradiation of Drosophila spermatocytes at a low dose rate.
A sex-linked recessive lethal mutation assay was performed in Drosophila melanogaster using immature spermatocytes and spermatogonia irradiated with X rays at a high or low dose rate. The mutation frequency in the sperm irradiated with a low dose at a low dose rate was significantly lower than that in the sham-irradiated group, whereas irradiation with a high dose resulted in a significant incr...
متن کاملLow dose hypersensitivity after high-LET irradiation
An unexpected hypersensitivity has been reported for several cell lines at low doses (<1Gy), which is not consistent with the linear-quadratic approach currently used in general for the description of survival curves [1,2,3,4]. The corresponding substructure of the survival curves has been attributed to induced radioresistance. There are indications, that high-LET irradiation with neutron or pi...
متن کاملLow-Dose X-Ray Irradiation Promotes Osteoblast Proliferation, Differentiation and Fracture Healing
Great controversy exists regarding the biologic responses of osteoblasts to X-ray irradiation, and the mechanisms are poorly understood. In this study, the biological effects of low-dose radiation on stimulating osteoblast proliferation, differentiation and fracture healing were identified using in vitro cell culture and in vivo animal studies. First, low-dose (0.5 Gy) X-ray irradiation induced...
متن کاملEffect of low dose X-irradiation on alloantigen sensitized and unsensitized lymphocytes.
The effect of local graft irradiation on' immune response in allograft in which acute rejection occurs was studied using an in vitro model. Unidirectional mixed lymphocyte culture (MLC) was used as the in vitro model of acute rejection.· 150 and 300 rad x-irradiation suppressed mixed lymphocyte reaction (MLR) but did not cell-mediated-lympholysis (CML) of unsensitized lymphocytes. X-irradiated ...
