After feeding of 20 d, 40 d and 60 d, the activities of nitric oxide synthase, bacteriolytic, superoxide dismutase, alkaline phosphatase and acid phosphatase in the serum were determined and the relativities between them were also analyzed.

在饲料中添加不同剂量的嗜酸小球菌投喂凡纳滨对虾，并在投喂后的20、40和60d，分别测定凡纳滨对虾血清中的一氧化氮合酶、溶菌活力、总超氧化物歧化酶、酸性磷酸酶、碱性磷酸酶，并分析了这5种酶之间的相关性。

IN 1997 the European Patent Office gave a patent to Massachusetts General Hospital for its use of nitric oxide to treat bronchoconstriction, a method often used for "blue baby" syndrome.

1997年，欧洲专利局为马萨诸塞州总医院颁发了一项专利，该专利是关于将一氧化氮用于支气管收缩方面疾病的治疗，这项技术有效缓解了患有先天性心脏病婴儿的症状。

Nitric oxide produced by PMA activated macrophages was released quickly, and then went down to a lower level. This process was related closely to the catonic amino acid transporter Y〓.

我们发现PMA激活的巨噬细胞产生一氧化氮有快速释放-速度下降的过程，并且这一过程与阳离子氨基酸转运系统Y〓密切相关。

In this dissertation, I will represent my studies on the nitration of Chalcone derivatives, reaction of epoxide ketone, and the aromatization of 3,5-disubstitued 2-isoxazolines with nitric oxide.

本文主要研究了：(1)NO与查尔酮及其衍生物的硝化反应，反应以较高的产率得到了a-硝基化合物；(2)NO对环氧酮的开环反应，反应生成了顺式羟基硝酸酯；(3)3，5-二取代的-2-异恶唑啉在NO作用下可以发生芳环化反应，生成了对应的2-异恶唑化合物。

The role of nitric oxide in abscisic acid-induced antioxidant defense in leaves of maize plants was investigated. Treatments with SNP or ABA enhanced the activities of chloroplastic, apoplastic and total superxide dismutase, catalase, glutathione reductase and ascorbate peroxidase in leaves of maize plants.

用硝普钠和ABA处理玉米幼苗，结果显示，ABA和SNP均增强了玉米叶片中抗氧化酶SOD、CAT、GR和APX的活性；激光共聚焦显微检测显示，ABA能够诱导叶片中NO的合成；NO清除剂PTIO和合成抑制剂L-NAME预处理阻断了ABA诱导的抗氧化酶活性的上升及NO的合成。

Objective To evaluate the role of nitric oxide in hyperdynamic circulation in cirrhotic portal hypertension.
