The hemodynamic effects of intravenous injection of agmatine and their cellular mechanism were investigated in anesthetized rats.

在麻醉大鼠研究静注胍基丁胺对血流动力学的影响，并初步探讨其机制。

Objective: This study investigates the damage of PC12 cells induced by Glutamate, and the possible neuro-protective effect of agmatine against the cell damage.

目的：研究一定浓度谷氨酸对PC12细胞的损伤作用，同时观察胍基丁胺对谷氨酸作用的影响，并初步探讨胍基丁胺的作用机制。

The method is to use glutamate with certain concentration to induce DNA injury of PC12 cell line and observe the effect of agmatine on DNA fragment and mitochondrial function simultaneously.

在用一定浓度的谷氨酸诱导PC12细胞DNA断裂的同时，观察胍基丁胺对其DNA断裂和线粒体功能的影响，发现胍基丁胺能明显减轻谷氨酸诱导PC12细胞DNA断裂并能改善线粒体功能。

Agmatine has no significant cytotoxic effect on PASMCs and agmatine dose-dependently inhibits the proliferation of rat PASMCs induced by hypoxia.

胍基丁胺对PASMCs不产生明显的细胞毒性作用；胍基丁胺可抑制低氧培养大鼠PASMCs的增殖，这种抑制作用呈剂量依赖性。

ABSTRACT The cardiac electrophysiological effects of agmatine were examined in guinea pig papillary muscle using intracellular microelectrode technique.

应用细胞内微电极技术，观察了胍基丁胺(agmatine， AGM)对豚鼠乳头肌细胞的电生理效应。

It has been well established that agmatine is an endogenous agonist at imidazoline receptors and noncatecholamine ligand at alpha - 2 adrenergic receptors (α2- AR).

业已证明，胍丁胺是一种内源性的咪唑啉受体激动剂和α2-肾上腺素能受体（α2-AR）的非儿茶酚胺配基。

It turns out that agmatine can inhibit PC12 cell line DNA injury induced by glutamate through block NMDA-R and improve mitochondrial function and reduce glutamate oxidative toxicity.

这说明胍基丁胺具有抑制PC12细胞DNA损伤的作用，其机制可能与其拮抗NMDA受体，改善线粒体功能和减轻谷氨酸的氧化毒性有关。

This is a special reaction of arginine's carbamidine, which is useful in quantitating and determining the natures of protein and the amino acid.

这是由于蛋白质分子中精氨酸胍基的特征反应。许多胍的衍生物如胍乙酸、胍基丁胺等也发生此反应。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
