精胺

At the stage of rapid cell expansion of longan fruit, the contents of free putrescine, sperdimine and spermine in aril rose rapidly, and maintained at a high level.

在果实迅速膨大期，假种皮内游离的腐胺、亚精胺、精胺含量迅速上升，并处在较高的水平。

In the model of photochemically induced brain ischemia, the putrescine content of cortex increased markedly.

在光化学诱导脑缺血6h和12h时，脑皮质腐胺含量明显增高，精脒和精胺呈下降趋势，在缺血12h时下降显著。

Polyamines including putrescine, spermidine, and spermine play important regulatory roles in mammalian cell proliferation and differentiaton.

多胺包括腐胺、精脒及精胺，在真核细胞增殖与分化过程中起着重要的调节作用。

Moreover,the endogenous putrescine and spermine titers were alsogreater in ultra-dried onion seed than that in the control.

超干种子内源多胺总量及精胺和腐胺含量显著高于对照种子，而亚精胺含量差异不大。

It was also observed that spermine could inbibit thegrowth of in vitro intestinal epithelial cells,which implied that thetrophie action of in vivo spermine might be indirect.

同时，我们还发现精胺能抑制体外肠上皮细胞的生长，提示体内精胺的肠营养作用可能是一种间接的效应。

As a carrier of plasmid DNA, dextran-spermine cationic polysaccharide was prepared by means of reductive-amination between oxidized dextran and the natural oligoamine, spermine.

作为质粒DNA的载体，阳离子的精胺多聚糖通过氧化右旋糖苷，精胺等之间的脱氨基化作用作用来制备。

ConclusionThe GC-SIM-MS method developed in this study has been shown to be suitable with acceptable reproducibility and recoveries for simultaneous determination of putrescine,spermidine and spermine as N-HFB derivatives in hair samples.

该方法使我们能更快更正确地同时检测头发样品中的腐胺、精脒和精胺，能在临床早期诊断和癌症预防方面有一定帮助作用。

Experiments showed that the contents of putrescine、spermidineand sperminein normal ovules were higher than those inabortive ones during the whole embryogenetic process.The highest levelswere reached 7 days after anthesis,with Put being the richest of thethree,then they declined.

试验结果表明：正常发育的胚珠中腐胺、亚精胺和精胺的含量在胚胎发育的各个阶段均高于败育胚珠，并在花后7d即达到最高值，其中Put的含量最高，随后都呈下降趋势。

The results showed that the treatment with spermidine promoted the activities greatly of SOD、POD and photosynthetic intensity but reduced the stomatal resistance to some extent ...

结果表明，亚精胺处理大大提高玉米幼苗中SOD、POD的活性以及光合强度，适当减小气孔阻力，故亚精胺可以提高玉米幼苗的抗旱性。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
