洋地黄毒甙对完整淡水龙虾（Procambarus clarkii）轴突静息膜电位的作用，以及在不同外细胞碱性土金属离子存在下的影响，使用细胞内微电极进行了研究。在外细胞pH值为7、6和5的条件下，明显的结合顺序是Ca2+大于或等于Sr2+大于Mg2+约等于Ba2+。

THE ACTION OF VERATRIDINE ON THE RESTING MEMBRANE POTENTIAL OF INTACT CRAYFISH (PROCAMBARUS CLARKI) AXONS IN THE PRESENCE OF DIFFERENT EXTRACELLULAR ALKALINE-EARTH CATIONS WERE STUDIED USING INTRACELLULAR MICROELECTRODES. AT EXTRACELLULAR PH VALUES OF 7, 6, & 5, THE APPARENT BINDING SEQUENCE WAS CA2+ GREATER THAN OR EQUAL TO SR2+ MORE THAN MG2+ APPROX BA2+.

从藜芦中提取的十一种生物碱对乌贼和淡水龙虾巨大轴突的膜电位和电导率的影响进行了比较。它们可以分为三组。1) 藜芦碱、藜芦胺和藜芦原碱A和B会导致膜去极化。效力按此顺序递减，藜芦碱和藜芦胺产生50%最大去极化所需的浓度分别估计为3.3 x 10-5 M和3.7 x 10-3 M。藜芦碱引起的去极化主要是由于静息状态下膜对钠的通透性选择性增加，并且可以被四环素毒素拮抗。所有这些物质都能有效增强并延长负（去极化）后电位。2) 藜芦胺、异藜芦胺、木藜芦胺（5-藜芦烷-3-β, 11-α-二醇-11-醋酸酯）和5-藜芦烷-3α-11α-二醇（1x10-4）能够阻断动作电位，而去极化很小或没有。5-藜芦烷-3-β, 11-α-二醇阻断了钠和钾电导率的增加。3) 环藜芦胺、藜芦胺、藜芦胺和藜芦醇对静息电位和动作电位没有影响。这些效果的可能的构效关系进行了讨论。

Eleven alkaloids obtained from Veratrum have been compared for their effects on the membrane potential and conductances of squid and crayfish giant axons. They can be classed in three groups. 1) Veratridine, cevadine and protoveratrines A and B cause the membrane to depolarize. The potency decreases in that order, and the concentrations of veratridine and cevadine required for 50% maximum depolarization are estimated to be 3.3 x 10-5 M and 3.7 x 10-3 M, respectively. The depolarization by veratridine is due primarily to a selective increase in resting sodium permeability of time membrane and is antagonized by tetrodotoxin. All of them are effective in augmenting and prolonging the negative (depolarizing) afterpotential. 2) Veratramin, eisorubijervine, muldaimine (5-veratranine 3-beta, 11-alpha-diol-11-acetate) and 5-veratranine-3alpha-11alpha-diol (1x10-4) re capable of blocking the action potential with little or no depolarization. 5-Veratranine-3-beta, 11-alpha-diol blocks both sodium and potassium conductance increases. 3) Cyclopamine, jervine, rubijervine and veratrosine have no effect on the resting and action potentials. Possible structure-activity relationships for these effects are discussed.

1X10-4摩尔的外部应用到乌贼轴突的藜芦碱导致膜的去极化。在初始去极化期间，由单一刺激引发的重复后放电随着膜的进一步去极化和动作电位的阻断而逐渐减少。去极化主要是由于膜静息钠渗透性的增加。

1X10-4 MOLAR VERATRIDINE APPLIED EXTERNALLY TO SQUID AXON CAUSED DEPOLARIZATION OF MEMBRANE. DURING INITIAL DEPOLARIZATION, REPETITIVE AFTERDISCHARGES INITIATED BY SINGLE STIMULUS SUBSIDED AS MEMBRANE FURTHER DEPOLARIZED & ACTION POTENTIAL BLOCKED. DEPOLARIZATION IS DUE PRIMARILY TO INCR IN RESTING SODIUM PERMEABILITY OF MEMBRANE.
