修复缺陷菌株中电离辐射诱导紫外线损伤。大肠杆菌审查。可以观察到光可再活化和非光可再活化类型的损伤。紫外线型损伤的诱导很大程度上与自由基反应剂(例如氧和硫醇)的存在无关,但取决于所使用的光子或电子束的能量、辐射几何形状和细胞外介质的光吸收率。根据计算和实验证据,很明显,产生这种损害的一种机制是通过切伦科夫发射的产生。然而,使用能量低于产生切伦科夫发射阈值的 X 射线可以产生少量的 UV 型损伤。在这种情况下,损伤诱发机制被认为涉及直接激励过程。
The induction of UV-type damage by ionizing radiation in repair deficient strains ofE. coliis reviewed. Both photoreactivable and non-photoreactivable types of damage can be observed. The induction of UV-type damage is largely independent of the presence of free-radical reactive agents (e.g. oxygen and thiols), but is dependent upon the energy of the photon–or electron–beam used, the radiation geometry and the optical absorbance of the extracellular medium. On the basis of calculations and experimental evidence, it is clear that one mechanism whereby such damage arises is through the generation of Cerenkov emission. However, small yields of UV-type damage can be produced using X-rays whose energy is below the threshold for production of Cerenkov emission. In this instance, the damage induction mechanism is thought to involve a direct excitation process.
