Abstract:: |
Objective To study the TCR gene mutation in peripheral blood lymphocytes induced by X-ray exposure using cultured lymphocytes cloning method.Methods Freshly isolated peripheral lymphocytes from healthy adult donors were irradiated with X-ray in doses ranging from 0 to 8 Gy and cultured with interleukin2 and phytohemagglutinin for 7 days. The mutant frequencies of TCR gene (TCR MF) were detected by flow cytometry and the dose response curves were fitted.Results TCR MF increased with the dose going up. An aquadratic polynomial dose response model was fitted.Conclusion TCR gene mutation could which serve as a potential biological dosimeter. It might be applied for the estimation of biological dose in emergency exposure. |
