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横断面的超微结构,并对有髓神经纤维的髓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。
