sciatic

Objective:To study the influence of ethanol on absolute refractory period of sciatic nerve in hoptoad.

目的:探讨乙醇对神经干绝对不期的影响。

Methods:We used ethanol at different concentrations for the sciatic nerve stem of the unorganized hoptoad and measures its absolute refractory period.

方法:本实验对离体蟾蜍坐骨神经干进行不同浓度乙醇处理,测其绝对不期。

Method PTPα deficient and wild type littermate mice of postnatal day 60 are employed.The ultrastructure of the cross section of sciatic nerve was studied under transmission electron microscope.

方法同窝出生60天的PTPα-/-和野生型小鼠，用透射电镜观察其坐骨神经的超微结构，并对有髓神经纤维的髓鞘厚度和数量进行形态计量分析。

Methods The sciatic and brachial plexus nerve of three-day-old SD mice was treated with collagenase type IV and trypsin to remove the desmocyte on the Schwann cell, then explanted in the culture disk.

方法:先用IV型胶原酶和胰蛋白酶消化出生3天的SD鼠臂层神经和坐骨神经组织块后再将组织块贴壁培养。
