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。

G-methyl-L-arginine, an inhibitor of NOS, inhibited the production of NO and recuperated the decrement in ATP content and KBR.

OS抑制剂NG－甲基－L－精氨酸可以抑制NO的产生，并使降低的肝细胞ATP含量、KBR得以恢复。

L-arginine, an NO precursor, reduced the contractile amplitude and end-diastolic cell length in the cardiomyocyte; but reversibly increased LVDP,±dp/dtmax, and coronary flow in isolated perfused rat heart.

2NO的前体L-精氨酸(L-arginine， L-Arg)引起心肌细胞舒张期细胞长度缩短、收缩幅度降低。离体灌流心脏LVDP、冠脉流量、和±dp/dtmax增高，用K-H液复灌后可恢复正常。

The purpose of the present study was to investigate the role of central arginine vasopressin in corticotropin releasing hormone-induced fever in the rat. Guide cannulae were inserted into the third ventricle and placed over the ventral septal area. The content of arginine vasopressin in the VSA of the brain was determined by radioimmunoassay. Colon temperature was monitored in lightly restrained rats by insertion of a catheter-mounted thermistor probe 5 cm in the rectum.

实验对大鼠进行第三脑室和脑腹中隔区插管，用数字体温计测量大鼠的结肠温度，用放射免疫分析法测定脑中隔区精氨酸加压素(arginine vasopressin， AVP)含量，观察脑中隔区AVP在大鼠促肾上腺皮质激素释放激素(corticotrophin releasing hormone， CRH)性发热机制中的作用。

Nitric oxide synthase catalyzes the stoichiometric conversion of L-arginine to NO and citrulline in the presence of oxygen and NADPH.

它是以精氨酸为底物，在一氧化氮合酶催化下产生的。

Coli culture . The recombinant enzyme was purified, dialysed and renatured, and exhibited arginine esterase activity, thrombin activity and fibrinogen cleaving activity without being released from the fusion partner. In animal model the recombinant protein significantly reduced rat blood fibrinogen level and inhibited experimental thrombus formation in rabbit.

融合蛋白通过纯化、透析复性，在未经肠激酶切的情况下，即测得精氨酸酯酶活性、凝血酶活性及纤维蛋白原降解活性；动物实验表明重组蛋白能降低大鼠体内纤维蛋白原的含量和抑制家兔实验性血栓形成。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
