腐胺

Objective:To study the alteration of ornithine decarboxylase activity and putriscine content in blood and tissue of patients with esophageal,gastric and colorectal cancer,and to explore their clinical significance.

目的：研究食管癌、胃癌和结直肠癌患者的血液和组织中鸟氨酸脱羧酶活性和腐胺含量的变化，并探讨其临床意义。

Of all tested plant growth substances, IBA, BA and ABA can promote the development of litchi pistil, while GA has no obvious influence on litchi pistillate and staminate development, putrescine precursor—arginine is helpful to staminate development.

在所试的植物生长物质中，IBA、BA和ABA对荔枝的雌蕊发育具有促进效应；GA对雌雄蕊的发育没有显著影响。腐胺的前体—精氨酸有利于雄蕊的发育。

This results indicate that there are a inherent pattern in metabolic disturbance of putrescine during brain ischemia.

表明腐胺代谢紊乱在脑缺血时有其固有的规律。

The research aimed to investigate the effects of putrescine on the tomato seed germination under NaCl Stress.

［目的］探讨腐胺对盐胁迫下番茄种子萌发的影响。

Four weeks after putrescine administration, the activity of ACT was increased and that of OCT decreased.

说明腐胺在体内对鸟氨酸代谢及嘧啶合成关键性酶活性有一定的调节作用。

The result suggeststhat putrescine could have significant potential for clin-ical treatment of acute pulmonary injury .

结果提示腐胺对于急性肺损伤可能具有一定的防治作用。

This drug can inhibit the putrescine content increased during 30 min reperfusion.

同时可抑制再灌流30min腐胺含量的增高，而且使脑电活动得到显著恢复。

The ischemic lesions was in correspondence with the level of putrescine content simultaneously.

这提示腐胺含量增高与脑缺血的病理损害密切相关，是一项反映脑缺血损害极有价值的生化指标。

Putrescine content reached the minimum when SWC was 75%.

腐胺含量在SWC75处理时最低。

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.
