The molecular charge distribution of the reactivator is affect the reactivating efficacy directly. Moreover its association with hydroximic acid dissociation constant pAa closely, and it will have a great impact on reactivating ability indirectly.(3) There is likely to exist front molecular interaction between Cholinesterase Reactivators and OPC-inhibited AChE, the action sites mainly lie on the aromatic ring, the substitute R and the hydroixic acid group. They act on the aromatic residues of AChE by Π-Π conjugation .(4) The reached results by Comparative Molecular Field Analysis is useful to design new higher efficacy derivatives for 1, 2, 4-oxadiazole class nonquaternary Cholinesterase Reactivators.

It was found that theintrduction of polar phosphatidylcholine to LLA chains had largely changed thehydrophilicity of the synthesized polymers. And from the research ofendothelioid cell (ECV304) compatibility and adhesion of blood platelet, wefound that the cells adhesion of ECV304 on the films of PLLA-PC-PLLA lagedcomparing to PLLA, but then could proliferate and cover the films in total,PLLA-PC-PLLA, the same as PLLA are not cytotoxicity and ECV304 canattach and proliferate on them, and PLLA-PC-PLLA can reduce the adhesion ofblood platelet.

ER, NGF and ChAT immunoreactive productions were widely presented in diencephalons, mainly in nucleus habenula, nucleus corpus geniculatum lateral, nucleus medialis thalami, nucleus lateral thalami, nucleus paraventricularis, nucleus paratenialis, nucleus rhomboidens, grisea periventricularis hypothalami, nucleus periventricularis hypothalami, nucleus paraventricularis hypoythalami, nucleus ventromedialis hypothalami, anterior region and posterior region hypothalami.

老年大鼠和去卵巢大鼠端脑大部分区域内ER、NGF和ChAT的表达活性及阳性细胞数目均显著下降，而补充17β－雌二醇后得到回升，并基本恢复到正常水平，表明雌激素通过ER对端脑内NGF和ChAT的表达有促进作用，这种作用可能部分地与雌激素对NGF的上调而作用于胆碱能神经元有关，也可能是雌激素通过ER直接调控了ChAT的表达，增强神经信息的传递。

In this thesis, two classes nonquaternary Cholinesterase Reactivators (1,2,4-oxadiazole and a -ketothio Hydroximic Acids derivatives ) and some clinical therapy used reactivators added to almost 40 cases have been caculated by using Comparative Molecular Field Analysis,ab initio and molecular mechanism methods. The characteristics of the molecular orbitals and the quantitative structure-activity relationship have been investigated.

本文利用比较分子力场法，量子化学从头算法，分子力学及计算化学回归分析等方法，对1，2，4-oxadiazole类非季铵肟胆碱酯酶复能剂，α—酮硫代异羟肟酸酯复能剂及部分现临床使用的复能剂，近40个化合物进行了计算，分析和研究了其电子结构和几何结构特征，建立了定量构效关系方程，得到了以下一些有意义的结果。

Sustained AF could be induced easily in all dogs during vagal nerve stimulation in vivo both before and after isolation of all PVs with encircling lesions created by a bipolar radiofrequency ablation clamp device. PV elimination had no effect on atrial effective refractory period or its responses to cholinergic stimulation. Autonomic ganglia were identified by bradycardic and/or tachycardic responses to high-frequency subthreshold local stimulation. Ablation of the autonomic ganglia overlying all PV ostia suppressed the effective refractory period-abbreviating and AF-promoting effects of cervical vagal stimulation, whereas ablation of only left- or right-sided PV ostial ganglia failed to suppress AF.
