衰老

The effect of calcium nitrate on relative physiological parameters of muskmelon softness was studied. The regulation measures of prolong fruit shelf-life were explored to provide theoretical basis for calcium use to prolong the optimal edible phase and shelf-life, and to learn the mechanism of calcium delaying the process of ripening and senescence.

研究硝酸钙对网纹甜瓜果实软化及其相关生理因素的影响，探讨延长网纹甜瓜货架期的调控措施，为生产上利用钙来延长网纹甜瓜的最佳食用期和货架寿命提供理论依据，并为进一步探明钙减缓果实成熟衰老的机制奠定基础。

The results showed that calcium nitrate treatment apparently slowed down the consenescence rate, made the flesh firmness higher than the control, elevated the activities of POD, SOD and CAT, retarded the ethylene production, reduced the soluble protein content, and declined the increased speed of electrical conductivity and LOX activity.

结果表明：硝酸钙具有明显延缓甜瓜果实衰老的作用，使果肉硬度显著高于对照，并提高过氧化物酶、超氧化物歧化酶和过氧化氢酶活性，同时降低果肉乙烯释放量、可溶性蛋白含量、外渗电导率的升高速度和脂氧合酶活性的作用。

The research on placenta through modern science show that its important ingredient is immuneglobulin and sneeiyne, which is the anti-aging gene, enzyme, which has high appliance value, and interferon, which protein can reach more than 80%, amino has rich resources、full ranges、and reasonable ration, which fat is less than 10%, and also has rich lecithin, cephalin, lipopolysaccharide, a variety of vitamins and trace elements,in addition, it has transfer factor, protein active factor, collagen element, organic phosphorus compound, amniotic acid and nucleic acid compound and so on.

采用现代科学对羊胎素进行分解，发现其重要成份是免疫球蛋白和延缓衰老基因sneeiyne具有很高应用价值的酶和干扰素，其中蛋白质的含量在80%以上，氨基酸含量丰富，种类齐全，配比合理，脂肪含量小于10%，还含有丰富的卵磷脂，脑磷脂，脂多糖，多种维生素和微量元素，此外，还有转移因子，蛋白质活性因子，胶原蛋白素，有机磷复合物，羊膜酸和核酸化合物等。

Immunoglobulin and anti-aging gene have a high value sneeiyne.sneeiyne enzyme and dry IFN-, in which the protein content of more than 80%, amino acid-rich.full range, areasonable proportion, Less than 10% aft content, but also rich in, cephalin, LPS, a variety of vitamin and trace element Su-, in addition to transfer factor, protein activating factor, collagen Su, organic phosphorus compounds, membrane acid And nucieic acids and other compounds.

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。
