查询词典 veratrine

Objective To observe the effects of low dose of veratrine on the discharges of rat hippocampus pyramidal neurons, and to elucidate its possible cytological mechanism.

目的 观察小剂量藜芦碱对大鼠海马CA1锥体神经元放电的影响，并对其诱发产生癫痫样放电的离子机制进行初步探讨。

Veratrine has anticarcinogenic chemical activity in the key stages of the development of cancer cells. It can kill the cancer cells and has no harm to the healthy cells.

白藜芦醇在癌细胞的起始，促进，发展三个重要阶段均有化学防癌的活性，能杀死癌细胞而对正常的细胞无毒害作用。

The subthreshold TTX-sensitive persistent sodium current of CA1 pyramidal cells was enhanced by veratrine in a voltage-dependent manner.

Ver灌流可增强TTX敏感的闭下持续性钠电流，并与膜电位水平有关。

Methods : Using direct pressure carotid tail artery and indirect pressure , duodenum and gavage to Veratrine . Determination of its normal cats , blood pressure in hypertensive rats and the impast of rapic tolerance .

采用颈动脉直接测压法和尾动脉间接测压法，十二指肠和灌胃给藜芦生物碱，测定了其对正常猫，高血压大鼠血压的影响及其快速耐受性。

Results After a perfusion with low dose of veratrine, the pyramidal neurons were found to discharge relatively fixed-mode slow wave epileptoid bursts accompanied with hyperpolarization of membrane potential.

结果 小剂量Ver灌流后随着膜电位的超极化，大鼠CA1锥体神经元产生模式相对固定的慢波样癫痫样活动。

Inducing slow wave epileptoid bursts, the low dose of veratrine can remarkably change the discharge features of CA1 pyramidal neurons.

小剂量Ver可明显改变大鼠海马CA1锥体神经元的放电模式，诱发慢波样癫痫电活动。

After a perfusion with veratrine, I-V relationship tended to be nonlinear and the depolarization rectification was enhanced, which were reversed by administration of low dose of TTX.

Ver诱发癫痫样活动后，I-V关系非线性化，去极化矫正增强，小剂量TTX可逆转此改变。

Methods The discharge features of hippocampus CA1 pyramidal neurons of 14-day-aged healthy Sprague-Dawley rats induced by low dose (0.3~0.8mol/L) of veratrine were observed by slice patch-clamp technique.

应用脑片膜片钳全细胞记录技术，观察小剂量(0.3~0.8mol/L)Ver灌流后SD大鼠（2~3周龄，共30只）海马CA1锥体神经元的放电特征。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
