衰老

Organism aging comes from cell aging, so study on diploid cell line is helpful to research the mechanism of aging.

机体的衰老来源于细胞的衰老，对二倍体细胞的研究有助于衰老机理的探讨。

Vacuum was satisfied to the requirement of fresh-cut taro package and benefit to reduce water loss and to inhibit browning. The treatment of insufflate fresh-cut broccoli with 20mg·L-1 6-BA could delay chlorophyll reduction, inhibit ion leakage increasing and slow down the process of senescence. Fresh-cut broccoli packed with the atmosphere combination of 2.5%O2+7%CO2+90.5%N2 had high Vc and high chlorophyll content, and the senescence of the products was delayed certainly. The gas mixture of 5%O2+ 2%CO2+93%N2 could reduce the rate of respiration, chlorophyll decomposition, membrane breakdown and tissue senescence of pakchoi.

真空包装适合鲜切芋头，降低贮藏中鲜切芋头的水分损失，抑制鲜切芋头褐变发生；用20mg·L~(-1)6-BA喷洒鲜切青花菜可推迟叶绿素降解，抑制相对电导率的增加，延缓了衰老；2.5％O_2+7％CO_2+90.5％N_2MAP包装的鲜切青花菜Vc含量较高，叶绿素荧光值也较大，明显延缓了鲜切青花菜的衰老：5％O_2+2％CO_2+93％N_2混合气体抑制了青菜的呼吸作用，降低了叶绿素降解速度，减缓了细胞膜损伤及组织衰老程度。

The results as follows:(1)The decrepit rules of Lycoris leaves were: the senescence of all leaves incarnated that they turned yellow from outside to inside; to the single leaves, the main type of senescence was that it was from tip to the edge gradually, and then went to middle nervation and to the base of leave finally. There was affinity between temperature and the senescence of lycoris longituba.

具体结果如下：(1)长筒石蒜叶片衰老形态的规律为：整株长筒石蒜叶片衰老主要是从外轮叶片逐渐向内轮叶片变黄；单个叶片的衰老主要类型是从叶尖开始逐渐沿着叶片边缘向叶中脉到叶的基部。

During maturation, ripening and senescence of tomato and strawberry fruits, calmodulin , a receptor protein of Ca〓, had similar changing trend, but the time when CaM peak appeared was different and related to storage life of fruit. CaM peak in strawberry fruit appeared earlier than in tomato fruit.

进一步研究表明，Ca〓受体蛋白钙调素(Calmodulin，CaM)无论在番茄还是草莓成熟衰老过程中，CaM含量变化均有相似的趋势，但不同果实CaM高峰出现的时间不同，衰老快的草莓果实较衰老慢的番茄果实CaM高峰出现时间早，这与果实的贮藏寿命有关。

objective to compare the anti-aging effects of lycium barbarum polysaccharides and tanshinone on the skin of d-galactose-induced mice aging model.methods 60 female mice were randomly divided into 4 groups (n=15):mice in normal control group received subcutaneous injection of normal saline and mice in the other 3 groups received cervicodorsal injection of d-galactose［1000 mg/(kg1·d)］ for 42 d to establish subacute aging model.the experimental groups included agingmodel group,lycium barbarum polysaccharides ［200 mg／group,tanshinone ［1 500 mg／］ group.forty two days later,the dorsal skin samples were collected to determine sod activities、mda and hydroxyproline contents.

目的 比较枸杞多糖与丹参酮对衰老小鼠皮肤的抗衰老作用。方法 60只雌性昆明种小鼠，随机分为4组(n=15)：正常对照组皮下注射生理盐水；其余3组每日颈背部皮下注射 d-半乳糖［1000 mg/］造成小鼠衰老模型，同时各组分别灌胃生理盐水、枸杞多糖［200 mg/］、丹参酮［1 500 mg/］。42 d后，测定小鼠背部皮肤组织匀浆中超氧化物歧化酶活力、过氧化脂质代谢产物丙二醛含量和皮肤羟脯氨酸含量。

Based on relate literature about the study on anti-aging efficacy of tuber fleeceflower root in recent years, the article summarized the study progress of the anti-aging mechanism of tuber fleeceflower root from cleaning free radical, repairing

文章参考了近年来何首乌抗衰老的有关文献，从清除自由基、修复损伤的基因、增强机体免疫功能、延缓细胞衰老等方面综述了在其抗衰老作用机制研究方面的进展。

Aging of reproductive system is considered to accelerate brain aging and increase the incidence of neurodegenerative diseases.

关于衰老机制的假说甚多，其中包括生殖系统衰老导致的性激素缺乏对脑衰老性病理改变的发展具有促进作用。

Results The ponderal index of brain, thoracic gland and spleen and SOD activity are significantly decreased, while the MDA content increased (P.01) in D-galactose-induced subacute mice. Shouwu soft capsule can improve the ponderal index of brain, thoracic gland and spleen and the SOD activity in blood serum and brain tissue and reduce MDA content.

结果：D-半乳糖诱导的亚急性衰老小鼠脑、胸腺和脾的重量指数明显下降，SOD活性明显下降(P.01)，MDA含量明显提高(P.01)等衰老改变，首乌软胶囊能够提高亚急性衰老小鼠脑、胸腺和脾的重量指数，提高血清和脑组织中SOD(P.01)活性，降低MDA含量(P.01)。

The brain starts ageing at 20; skin starts to age naturally in the mid-20s; muscles start ageing at 30, but regular exercise can help prevent this; and the voice starts ageing at 65, becoming quieter and hoarser.

研究显示，大脑20岁开始衰老；皮肤25岁左右开始衰老；肌肉30岁开始老化，但常锻炼有助于预防肌肉老化；发音器官则从65岁开始衰老，声音变得轻声细气，越来越沙哑。

Treated with medicine-separated moxibustion on Shenque acupoint, the aging process of the monoamine neurotransmitters in the cerebral cortexes of senile model rats can be slowed, the ability of eliminating free radicals can be enhanced, and the memories of the rats can be improved.

隔药灸脐法对提高衰老模型大鼠抗氧化系统清除自由基的能力及改善衰老大鼠脑内单胺类神经递质的增龄性变化具有良好的疗效，同时可提高衰老大鼠的学习记忆能力，为隔药灸脐法的临床应用提供了一定的实验依据。

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。
