查询词典 ACH

In recent years, ENK-IR neurons in myenteric plexus have been discovered. ENK is one of the important neurotransmitters in ENS. It can reduce the amplitude of cholinergic fEPSP and the release of Ach so as to inhibit contraction of smooth muscles.

近年发现在肠肌间丛神经元中有ENK-IR神经元，脑啡肽是肠神经系统中重要的神经递质之一，可降低胆碱能快速兴奋性突触后电位的幅度，减少乙酰胆碱的释放，抑制平滑肌的收缩。

Objective To observe the effects of urapidil,phentolamine,glyceryl trinitrate or phenylephdrinum on the isolated tracheal smooth muscle in rabbit.Methods KCl,Ach and electrical stimulation were used to induce the contraction of the isolated rabbit tracheal smooth muscle.

目的 观察常用降压药和升压药对气管平滑肌张力的影响，探讨其作用机制方法观察不同浓度乌拉地尔对氯化钾、乙酰胆碱、电脉冲三刺激因素诱发的兔离体气管平滑肌收缩力变化的影响；观察酚妥拉明、去氧肾上腺素和硝酸甘油对电刺激诱发的气管平滑肌收缩力的影响。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

Acclimatization 1.73±1.82** 0.61±0.06 0.98** P＜0.01 vs normoxic rats.After the aorta preparations were precontracted with NE at the concentration of 0.62 μmol/L, a ccumulative vasodilative effects of ACh were tested.

与常氧对照组相比，急性低氧和间断低氧习服后，大鼠主动脉对ACh各浓度(10- 9～10-5 mol/L)引起的舒张反应显著减弱(P＜0.01)，其最大舒张分别为常氧对照组的87.3％和79.7％，其EC50值分别为1.34和1.73 μmol/L，分别为常氧对照组EC50值0.20 μmol/L的6.7和8.6倍(表2)。

The mechanical contraction of circle muscularis strips, the contractile response of dispersed smooth muscle cells, the change of 〓 stimulated by sennoside with different concentration and that stimulated by Ach after incubated with sennoside were evaluated. The translocation of RhoA by sennoside were measured by laser confocal scanting microscopy too.

检测不同浓度的番泻甙对小肠环行肌条和游离环行平滑肌细胞的收缩作用及对〓的影响，然后测定番泻甙对Ach刺激的小肠环行肌条、游离环行平滑肌细胞收缩反应和细胞内〓变化的影响作用，并通过免疫荧光实验检测番泻甙对RhoA的活化和空间转位的影响。

谈谈你的工作业绩好吗？

"Ach, no," he said, go home; you have worked enough to-day.

&哦，不用，&他说，回家吧；今天你干得够累了。

Results: Compared with the C group, the contents of CORT in blood and ACTH in pituitary gland are increased at the different time points.
