Abstract

Experimental data on photoreactivation of damage induced by ionizing radiation in yeast cells are presented. The value of photoreactivation was found to be the highest for the following conditions predicted by us as optimum ones: large volume of irradiated suspension, hypoxia and high energy sparsely ionizing radiation. A comparison of data for yeast and bacterial cells shows that Cerenkov emission from ionizing radiation may produce photoreactivated pyrimidine dimers in both prokaryotic and eukaryotic cell systems.

摘要

本文给出了酵母细胞中电离辐射所致损伤的光复活实验数据。结果发现，在我们预测为最佳的以下条件下，光复活值最高：大量受辐照悬浮液、缺氧以及高能稀疏电离辐射。酵母细胞与细菌细胞的数据比较表明，电离辐射的切伦科夫辐射可在原核和真核细胞系统中产生光复活嘧啶二聚体。
