The results showed that UK14300 3×10~(-6 mol/L, a potent #alpha#_(2)-adrenoceptor agonist,significantly inhibited both basal and endotoxin-induced CGRP release by 22%-42%,while specific antagonist of #alpha#_(2)-adrenoceptor yohimbine 10~(-5 mol/L blocked the effect of UK14304 completely.

结果发现，α_(2)-受体激动剂UK143043×10~(-6mol／L可以显著抑制CGRP的基础释放和内毒素(1～5μg／ml)刺激后的释放，抑制幅度为22％～42％；用α2-受体拮抗剂Yohimbine(10－5mol／L)可以完全阻断UK14304的作用。

Anti-aging effects of non-lead and non-nickel antiager of 4,4 -Bis(alpha,alpha-dimethylbenzyl)diphenylamine(445)and 2-phenyl mercaptan parallelism imidazole were dealt with on the mechanical properties and vulcanizing performance of epichlorohydrin rubber.

研究了不含铅、镍重金属盐的防老剂445[4，4′-双(2，2-二甲基苄基)二苯胺]和2-硫醇基苯骈咪唑用于氯醚橡胶的防老化作用，考察了防老剂对ECO的力学性能和硫化特性等性能的影响。

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.

本研究发现：1、对照组大鼠行为无异常，伏核EEG以α节律为主，散在出现δ和θ节律；功率主峰在δ和θ频段范围，整个过程中未发现手术对伏核EEG及脑电功率谱有影响。2、在慢性饮酒过程中，大鼠攻击性行为增加，伏核 EEG的α节律明显减少，散在出现的高幅慢活动δ波逐渐增多，功率谱分析表明δ频段功率百分比明显增加，而θ频段功率百分比明显减少，总功率减少。3、停饮后，大鼠出现湿狗样抖动、打喷嚏等撤药综合症，并且高频声音刺激能引发惊厥；伏核EEG出现棘波和棘慢综合波，并持续增多，功率谱分析显示δ频段功率百分比 5 南京医科大学硕士学位论文逐渐减少，而0和以频段功率百分比逐渐增加，总功率增加。

The pain predicate applies to you, the octopus, and the Alpha Centaurian, not because you share a single higher-level property, but because you, the octopus, and the Alpha Centaurian possess similar, although not precisely similar, properties.

疼述词用在你和章鱼上，不是因为你们分享一个单一的高阶属性，而是因为你们拥有相似的、但不是完全相似的属性。

You, an octopus, and an Alpha Centaurian could all be in pain despite your very different physiologies (pretend that Alpha Centaurians have a silicon-based 'biology').
