采用~(60)Co源γ射线外照射新西兰兔后臀部皮肤后,观察局部组织胶原代谢指标及全身和局部与胶原代谢相关的生化指标,并研究了不同年龄性别组Wistar大鼠皮肤胶原含量及型别分布差异,以阐明γ射线所致放射性皮肤损伤中胶原代谢变化的分子机制。实验结
After external irradiation with ~ (60) Co γ-rays on the buttocks of New Zealand rabbits, the local tissue collagen metabolism indexes and the systemic and local biochemical indicators related to collagen metabolism were observed. The skin collagen content of Wistar rats at different age groups and Type distribution differences in order to clarify the molecular mechanism of γ-ray radiation induced skin damage in collagen metabolism changes.
