对化学防护作用资料的分析使我们提出一个实现不同辐射防护剂防护作用的一般方式。另一方面,同一种动物辐射耐受性的个体差异很大,使人们去寻找造成这些差异的生理机制。为此研究了辐射耐受性明显不同的雌性动物的二个生理状态,雌性小鼠、大鼠和豚鼠在雌激素活性分泌期对辐射较敏感在孕激素活性分泌期和性激素阈下分泌期(动情后期和动事间期)对辐射较不敏感(约2倍)。对与性周期有关的雌性动物组织中某些代谢和
Analysis of chemopreventive data has led us to suggest a general way of achieving the protective effects of different radioprotectants. On the other hand, individuals in the same animal tolerant to radiation vary so widely that one looks for the physiological mechanisms that contribute to these differences. For this purpose, two physiological states of significantly different radiation tolerance in female animals were studied. Female mice, rats, and guinea pigs were more sensitive to radiation during the estrogenic activity during the secretory phase of progestin activity and subliminal secretory phase of sex hormone Late estrus and intercourse) less sensitive to radiation (about 2 times). Some of the metabolism and tissue of female animals associated with sexual cycles
