Objective:To study the influence of ethanol on absolute refractory period of sciatic nerve in hoptoad.
目的:探讨乙醇干绝不期的影响。
Methods:We used ethanol at different concentrations for the sciatic nerve stem of the unorganized hoptoad and measures its absolute refractory period.
法:实验离体蟾蜍坐骨干进行不同浓度乙醇处理,测其绝不期。
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.
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横断面的超微结构,并有髓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.
法:先用IV型胶原酶和胰蛋白酶消化出生3天的SD鼠臂层和坐骨组织块后再将组织块贴壁培养。
