The following results have been observed.(1) When the membrane potentials of a neuron were depolarized or hyperpolarized stepwise from a resting potential via recording pipette to inject a DC current, the frequency and/or amplitude of mIPSCs increased or decreased respectively.

观察到以下结果：（1）当通过改变记录电极内的 DC电流，将神经元的膜电位从静息电位逐步（每步10mV的增量）去极化或超极化时，mIPSC的频率和/或振幅分别升高或降低。

To further study the effects of 〓 elevation on glycine response as well as glycinergic neurotransmission, neurons were dialyzed with high 〓 pipette solution, leading to 〓 overload.

For example, by using females that had just been killed for other assays, we learned how to carefully insert the pipette into the urogenital opening without lacerating the female.

我们也从中学到了如何在不割开鱼体的前提下轻轻的插入管子进入生殖孔同样的对于公鱼来说，我们也学到了最好的获得精液的挤压方法。

Results In contrast with enzymatic dissociation, the method of mechanical dissociation, breaking up great neurospheres into small spheres with gradually reduced pipette, had advantages of raising cell viability and shortening cell doubling time (P.05). After NSCs being cultured long term in vitro, the number of neurons generated decreased with passaging, whereas the number of astrocytes increased.

体外长期培养条件下，随着培养时间的延长，NSCs分化为神经元的比例逐渐降低，星形胶质细胞的比例逐渐增高；在4~12代NSCs分化为神经元的能力表现出下降的趋势，但仍较为稳定；12代后，神经元的分化比例迅速下降，星形胶质细胞的比例迅速上升。

Results The linearity range was 5~500μg/mi. The linear regression formula was Y=5.9601 X -1.643, r=0.9998. The limit of detection was 0.5μg/ml. The minimum detectable concentration was 0.04mg/m^3 (60 L sampling volume). The sampling efficiency was 100%. The sample could store at least 5 days in absorption pipette.
