The fEPSP response evoked in one pathway was small, usually 20–30% of the maximu, whereas a large response, usually 80–90% of the maximum, was evoked in the strong pathway. After recording of the baseline fEPSP evoked at 0.033 Hz, LTP of the weak pathway could be associatively induced by paired stimulation of the weak and strong pathways 100 times at 6 sec intervals, with stimulation of the weak pathway preceded 3–10 msec.

在记录以0.033Hz所引发基础的兴奋性突触后电位之后，在弱的路径上可以因配合弱与强的刺激路径而引发出相关性长期增益（每六秒一次共100次，弱的刺激路径在强的刺激路径之前 3-10 ms），然而当在两个路径之间的配合时间差大於10 ms时即无法形成相关性长期增益，此类型长期增益的引发是需要依赖活化NMDA接受器的，因为给予50 mM的D，L-AP5可以阻断相关性长期增益的引发（兴奋性突触后电位为原来的105±6﹪；n=6）。

After thermodynamic studies on the former two typical fine disseminated gold deposits, the following facts are found: both existent and transferring form of gold in mineralizing hydrothermal solution are predominated by Au 〓 and AuH〓SiO〓; the contribution of AuCl〓〓 is negligible to mineralization; and those contribution of gold bearing complexes including Au with As-S and Sb-S are much less than that of Au 〓 and AuH〓SiO〓, organic complex take effect in some degree during the relatively low temperature activating period of gold.

对以上两个典型微细浸染型金矿床的热力学研究，发现成矿热液中金的存在和迁移形式均以Au〓和AuH〓SiO〓为主，AuCl〓对金迁移成矿的贡献微不足道，金砷硫或金锑硫等复合配合物对金成矿的作用远不及Au〓和AuH〓SiO〓，有机配合物在温度较低的金的活化期有一定作用。

Aside from pancreatic enzymes activiation and autodigestive process, recent investigations have established that the upregulation of inflammatory mediator are believed to be the critical steps in the progression of mild pancreatitis to severe pancreatitis. Tumor necrosis factor-, ThyomboxaneA2 ,ProstaglandinsI2 are all important inflammatory mediator. TNF-( is one of cytokines. It is important to the over-production of ICAM-1,VCAM-1, TXA2 andPGI2. The ICAM-1 and VCAM-1 mediate both leukocytes adhesion and migration through the endothelium into tissues to connect with injuried target cells. The TXA2 and PGI2 are the production of arachidonic acid. They are responsible for the tissue ischaemia.

肿瘤坏死因子（Tumor necrosis factor-， TNF-、血栓素A2（ThyomboxaneA2，TXA2），前列环素（ProstaglandinsI2，PGI2）均是炎症反应中重要的炎性介质，其中肿瘤坏死因子-是非常重要的细胞因子之一，它由活化的单核细胞产生，在细胞间黏附分子（Intercellular adhesion molecule-1，ICAM-1）及血管细胞黏附分子(Vascular cell adhesion molecule-1，VCAM-1的表达、血栓素A2及前列环素过量生成方面起着重要的作用，前两者是介导白细胞与内皮细胞黏附，迁移于组织并与受损的靶细胞相结合的主要媒介，是炎症反应中的重要介质，后两者是花生四烯酸的代谢产物，亦是重要的炎性介质，参与构成血液循环障碍。

Under certain experimental conditions,the Terbiumbasic Calbonate can be dissolved in aqueous solution of nicotinic acid to yield an Orange Tb Complex, which has a broad characteristic absorption band between, 370—410 nm The autoreduction of the Tb—Complex was studied by means of spectrophotometric method, It was determined by experiments that the reaction order is equal to two and the apparent activation energy of the auto—reduction is equal to 68.4±0,8KJ/mol.

在一定条件下，Tb的碱式碳酸盐可以溶解在烟酸的水溶液中形成橙黄色的络合物，该络合物在390nm波长附近有一宽带特征吸收峰。消光值在0。～1.0范围內与Tb的浓度具有直线关系。分光光度法对Tb自还原反应研究确定：于15℃及烟酸浓度为0.35M时，当pH值小于6.0条件下，随pH值的增加，其自还原速度常数减小，该自还原反应级数为二，反应活化能为68.4±0.8KJ/mo1。

The value of current density and the apparent active energy of electroreduction of substituted nitrobenzene depend on the electronic effect of substituted group and space resistance. o,m,p-chloronitrobenzene will be electroreduced to azoxy compounds by taking three electrons, o,m-nitrotoulene and o,m-nitrobenzoic acid will be reduced to phenol compounds by taking four electrons, and p-nitrotoulene will be reduced to the aniline by taking six electrons. According to these results, the electroreduction mechanism of the substituted aryl nitro-compounds was studied in detail.

"Anti-platelet drugs are often used to reduce intima thickening, for example, restenosis...after angioplasty. Perhaps a different method of inhibiting platelet activation would be to drink dealcoholized beer," Dr. Bassus says."Conversely, the acute consumption of alcohol beverages causes an increase of thrombin generation, suggesting a thrombotic risk in case of acute alcoholic intoxication."

抗血小板药物一般被用来降低血管内膜的肥厚症状，如该药物可预防血管修复手术后的血管狭窄现象，Bassus表示，也许抑制血小板活化的另一种方法就是投予去醇啤酒，然而，过度的酗酒反而会造成凝血酵素的增生，也就是说，急性酒精中毒通常会有缺血的风险。
