Results:The three groups of P77PMC rats which experienced 30 and less than 30 times of audiogenic seizure and the Wistar control group did not display MF sprouting in dentate gyrus, however, the group of P77PMC rats which experienced 50 times of AGS was found hippocampal MF sprouting into the inner molecular layer of dentate gyrus.

结果：在全身性强直阵挛性惊厥发作次数少于30次的P77PMC大鼠以及对照的Wistar大鼠海马内均未见到MF发芽表现；而在经历50次Ⅳ～Ⅴ级听源性惊厥发作的一组P77PMC大鼠海马内观察到了MF发芽的现象，在海马齿状回内分子层内见到Timm染色呈棕黑色颗粒异常分布的MF末梢。

Computer-simulated results show that the introduction of acetylene bridge,which electron cloud is columned,reduced the space block between molecular functional groups.In the acetylene-bridged system,the functional groups can keep relatively free rotation,which resulted in that the conjugated electronic cloud are influenced,and then influenced on the properties of the compounds.

计算模拟结果证明，炔桥的引入降低了星状分子的核单元官能团和臂单元官能团之间的空间位阻，使得官能团可以比较自由的旋转，从而对核-臂之间的电子云共轭产生影响，继而影响到该系列化合物体系的各种性能。
