免疫组化结果显示AQP4和AQP9阳性物质在脉络丛、SFO、室管膜、海马、视上核和室旁核等处表达，表现为胞膜着色，胞浆和胞核不着色，烧伤后各时间段其表达较对照组均有显著增加，在伤后6h达高峰。

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

Since the first extragalactic H2O megamaser source toward the Active Galactic Nuclei NGC 4945 was discovered, 19 sources have been found.

自从在活动星系核NGC 4945的视线方向上发现第一个河外H2O超脉泽源以来，迄今为止已发现了19个河外H2O超脉泽源。

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。
