将狗于1.0—5.0戈瑞~(60)Co-γ线照射和该剂量复合15％二度烧伤,单纯烧伤和对照组之间,放射加热复合烧伤和单纯照射组之间,离体照射和整体照射之间,染色体畸变无显著性差异。经回归分析表明,不仅配合的模式相同,而且同一指标的回归系数相当接近,狗复合15％二度烧伤对外周血淋巴细胞染色体畸变未产生影响。因此,染色体畸变分析有作为放射加热复合烧伤时“生物剂量仪”的可能性。 The dogs were treated with 1.0-5.0 Gy-60 Co-γ radiation and the dose of 15% second-degree burns. Between burn and control group, There was no significant difference in chromosomal aberrations between the whole irradiation. Regression analysis showed that not only the pattern of cooperation was the same, but also the regression coefficient of the same index was quite close. The 15% second-degree burns of dogs did not affect the chromosomal aberrations of peripheral blood lymphocytes. Therefore, the analysis of chromosomal aberrations has the potential as a “biological dosimeter” for radiation-heated composite burns.
