摘要
本工作在四只狗上建立了延缓条件反应,观察体内电离辐射对动物学习记忆的影响。结果显示,静脉注射放射性硝酸钍,剂量为每次10毫克/公斤体重,每日一次;总注入量平均8.68克,超过允许剂量350倍;没有引起延缓条件反应的明显障碍。这表明狗的瞬时记忆对于放射性灶电离辐射的耐受力是比较强的。
Delayed conditioned responses were performed in four dogs in a maze.The effect of ionizing radiation of thorium on learning and memory wasobserved. The results showed that after 62 doses (10mg/kg. a dose, delivered oncea day) of chronic injections of thorium nitrate intravenously, theaccumulated dosage was 8.68g on the average, which exceedes themaximum permissible dose by 350 times, no obvious deterioration of thedelayed conditioned response was observed. This means that the immediatememory in dogs is rather invulnerable to ionizing radiation of thorium.
