衰老

It also is an important aspect of antiaging mechanisms of MT.

本研究结果表明，MT能够提高老年小鼠脑中神经营养因子的表达水平，这对于延缓脑细胞的衰老过程，阻止脑结构萎缩以及功能下降，保护CNS神经元可能具有重要意义，也是MT抗衰老作用的一个方面。

Although caducity is inevitable like ratepaying, but happiness can slow down the process.

虽然衰老像纳税一样不可避免，但快乐可以减缓衰老。

Although caducity is inevitable like ratepaying, happiness can delay caucity.

虽然衰老就像纳税一样不可避免，但快乐可以避免衰老。

Muskmelon discs taken at ripening stage were used by different concentrations of calcium nitrate (1, 3, 5 mmol/L) and various time (4, 8, 12, 16, 20, 24 h) in order to investigate related to maturation and consenescence physiological parameters.

为明确钙在调节网纹甜瓜果实成熟衰老中的生理作用，以网纹甜瓜果实圆片为材料，研究了不同浓度硝酸钙(1，3，5 mmol/L)处理4，8，12，16，20和24 h情况下，甜瓜果实成熟衰老相关生理指标的变化。

Moreover, compared with 1 mmol/L and 3 mmol/L, 5 mmol/L treatment more significantly slowed down the maturation and consenescence process of muskmelon. Meanwhile, compared to the calcium nitrate treated for 4 h and 8 h, the discs treated for 12 h were more apparently promoted or inhibited based on above maturation and consenescence physiological parameters; however, with the prolonging of treated time to 24 h, the activities of POD, SOD and CAT dropped markedly, as well as the inhibition of synthesis of soluble protein, and the increased speed of electrical conductivity and LOX activity were reduced markedly.

与1 mmol/L和3 mmol/L的硝酸钙相比，5 mmol/L的硝酸钙处理更能显著延缓果实的衰老进程；与处理4 h和8 h相比，处理12 h硝酸钙对以上各成熟衰老指标的促进或抑制作用效果更加显著，但是随着处理时间的延长至处理24 h时，POD、SOD、CAT活性反而下降，对可溶性蛋白的合成、外渗电导率和LOX活性升高速度的抑制效应显著降低。

Therefore, researching the relationship between spleen deficiency and decrepitude and investigating its effective mechanism have most important realistic significance in the course of medical practice to postpone decrepitude.

因此，深入研究脾虚与衰老的关系，进一步明确其作用机制，在延缓衰老的医学实践中无疑有极为重要的现实意义。

Its principal is, such product can control some genes, reopen those genes that been closed while you were young, and close genes which leads decrepitude. This is a profound change in human life.

其抗衰老的原理是它能操纵一些基因，使已经关闭的年轻时的基因重新开启，让导致衰老的基因关闭，对人类健康延寿具有深远的意义。

In the theoretical study section, this thesis considered that spleen and stomach dominates inYuan Shen motion, and AD is pathological dotage which the appearance of mind disturbed with brain aging.

在理论研究部分，从脾在元神运动中的重要作用入手，我们认为AD是以神志病变为特征的病理性衰老产生的疾病之一，是因衰老而致神机失用的脑病态表现。

The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料开花以前具有比较高的根系活力、可溶性蛋白含量、SOD和CAT活性；开花以后，根系活力、旗叶可溶性蛋白含量、SOD和CAT活性快速下降，MDA含量快速上升，衰老加快；相关分析表明，延缓小麦旗叶衰老进程，可以促进花后氮素和干物质运转，增加花后氮素和干物质积累，提高籽粒产量和籽粒氮素积累量。

Objective By using the D-galactose-induced aging mice,the effects and mechanism of Ginkgo flavone on aging were investigated.

目的 研究银杏黄酮对D-半乳糖所致小鼠学习记忆能力下降和各项衰老指标的对抗作用，以期探讨银杏黄酮的抗衰老作用机制。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
