The effect of Co60 gamma radiations on the amplitude, detection period and duration of the action potential of sciatic nerves of Rana Tigrina frogs have been studied. Dose levels of up to 120 KR were employed. Irradiation of the nerves with dose levels upto 30 KR does not seem to affect the action potential profiles. The amplitude falls rapidly therafter, registering less than 5% of the orginal value after irradiation by a dose of 120 KR. Qualitatively similar behaviour is seen in the case of detection period and duration of action potential. These results are examined in the light of the authors' data (11) on the effect of Co60 gamma rays on the enzyme acethlcholinesterase (AchE). Portions of this paper have already been communicated (12).
研究了钴60γ射线对虎纹蛙坐骨神经动作电位的幅度、检测期和持续时间的影响。采用了高达120千伦琴的剂量水平。用高达30千伦琴的剂量水平照射神经似乎不会影响动作电位曲线。此后幅度迅速下降，在照射120千伦琴剂量后记录到的幅度不到原始值的5%。在动作电位的检测期和持续时间方面也观察到定性相似的行为。根据作者关于钴60γ射线对乙酰胆碱酯酶（AchE）影响的数据（11）对这些结果进行了研究。本文的部分内容已发表（12）。
