Abstract
  1. The net movements of Na and K into resting squid giant axons perfused with a K(2)SO(4) artificial axoplasm have been determined. Na enters at a rate of 131 +/- 25 p-mole/cm(2).sec. The K leakage from the fibre is 942 +/- 566 p-mole/cm(2).sec; clearly this latter figure shows how large is the uncertainty in the exact value for the potassium leakage.2. The net entry of sodium associated with activity in such fibres has been measured and is 5.7 +/- 0.7 p-mole/cm(2).impulse.
摘要
  1. 已测定了钠和钾进入灌注硫酸钾人工轴浆的静息乌贼巨大轴突的净移动情况。钠以131±25皮摩尔/平方厘米·秒的速率进入。纤维中钾的漏出量为942±566皮摩尔/平方厘米·秒；显然，后一个数字表明了钾漏出精确值的不确定性有多大。2. 已测量了此类纤维中与活动相关的钠的净进入量，为5.7±0.7皮摩尔/平方厘米·冲动。
