本课题以中医药理论为指导，依据益气养阴方和益气补肾方的功效与应用，结合目前运动性疲劳和衰老的产生机制等方面的研究进展，采用现代药理学研究方法，观察益气养阴方和益气补肾方对环磷酰胺致小鼠免疫抑制的抵抗作用及对小鼠常压耐缺氧和断头后张口喘气时间的抗应激能力，同时分别采用运动性疲劳大鼠模型和自然衰老大鼠模型进一步探讨益气养阴方抗运动性疲劳机制及益气补肾方抗衰老机制。

Huang-hua' pear fruit was a typical climacteric fruit after harvest, and the fruit senescence-related factors, such as LOX activity, 02" content, AOS activity, ACC synthase activity, ACC content, ACC oxidase activity and ethylene production, changed with peaks at 20 "C. The activities of LOX, AOS, ACC synthase, ACC oxidase and the accumulation of O2 ", ACC content and ethylene synthesis were inhibited when stored at 1癈. And the severity of flesh floss and fruit decay was lightened. Low temperature combined with polyethylene film bag packing (PEF1 and PEF2) could further decrease the rate of weight loss, flesh floss, and fruit decay and keep preferable freshness. When PEF1 and PEF2 packing fruits were transferred to shelf life at 20 "C after storage at 1癈. The activities of LOX, AOS, ACC synthase, ACC oxidase could be suppressed and the accumulation of 02 , ACC content and ethylene production were slowed down to a certain extent, especially during the shelf life after 60 d storage. PEF1 and PEF2 packing fruit could maintain higher firmness as well, and the effects became more distinct along with the storage period, there existed no significant difference between PEF1 and PEF2 treatments.

试验结果表明，在20℃下，LOX活性、O2-水平、AOS活性、ACC合成酶活性、ACC含量、ACC氧化酶活性及乙烯的生成，均呈峰形变化；1℃处理可抑制LOX、AOS、ACC合成酶、ACC氧化酶的活性和O2-、ACC的积累，抑制贮藏果实的乙烯合成，减轻果肉发绵和果实腐烂。1℃下贮藏的果实，若结合不同聚乙烯薄膜袋(PEF1和PEF2)小包装，可以进一步降低果肉发绵率和果实腐烂率，保持果实新鲜度；当果实经过一段时间贮藏后，转移到20℃下，在货架期间，PEF1和PEF2对果实成熟衰老各个相关因子均有不同程度的抑制效应，主要表现在贮藏60d后的货架期间，同时维持较高的果实硬度，对硬度的影响随着贮藏时间的延长愈加明显，PEF1和PEF2处理效果之间无显著差异。

Golden pear could keep high quality over 100 days if stored at 5 centigrade, because the low temperature had influenced it in many aspects:(1) Made weight loss ratio lower than normal, and no fruit rot appeared;(2) Keep high fruit firmness all through the storage;(3) Respiratory climacteric came forth later than that which stored at room temperature, and the peak was lower than normal;(4) Activity of LOX and PG were inhibited, so the process of fruit senescence was delayed effectively.

7.5℃低温贮藏可以使黄金梨果实贮藏期延长至100天以上，并长期保持其优良商品特性，主要在以下几方面对果实产生影响：(1)降低黄金梨果实的失水率、防止烂果的发生；(2)延缓果实硬度下降的进程；(3)延迟果实呼吸峰的到来，并使峰值降低；(4)有效抑制黄金梨果实中LOX、PG的活性，从而延缓果实的衰老过程。
