By methods of IR-spectroscopy, electrophoresis and piezomicrobalance the comparative study on hydration and structural state of liver DNA from rats both intact and exposed within the Chernobyl accident zone was conducted. Modification of primary and secondary DNA structure in irradiated animals demonstrate serious disturbance of hepatocyte genetic apparatus. This is responsible for previously found considerable morphologic and ultra-structural changes in rat liver tissue after prolonged exposure to low-level ionizing radiation in the Chernobyl accident zone.
通过红外光谱、电泳和压电微天平等方法，对来自切尔诺贝利事故区未受辐射和受辐射大鼠的肝脏DNA的水合作用和结构状态进行了比较研究。受辐射动物体内DNA一级和二级结构的改变表明肝细胞遗传装置受到严重干扰。这与之前在切尔诺贝利事故区长期暴露于低水平电离辐射后大鼠肝脏组织中发现的显著形态学和超微结构变化有关。
