A, and H319A exhibited an injury of proton translocation ability and show a decrease in the coupling efficiency but not PPi hydrolysis. They also locate at one face of the helix wheel, implicating their involvement in proton translocation.

由此猜测，这三区具有维持稳定结构的功能。A305S， V308A， A310S， G316A与H319A仍保有活性但降低了偶合效率，且位在螺旋环柱的同一面，暗示这些胺基酸可能与质子运送有关。

In addition to the common effect of supplementing qi, YiQiYangYin Fang has unique clinical application in exercise-induced fatigue disease because of its function of reinforcing yin; YiQiBuShen Fang is used for treating senescence diseases by reason of its function of invigorating kidney.

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。

The percentage of hemizygous LOH in CP-induced mutants (50%) was 2.4 times than that of the control (20.7%).

环磷酰胺诱导产生半合子LOH的比例(50%)是对照(20.7%)的2.4倍。

MethodsPolyprenols separated and purified from ginkgobiloba L were administered alone and in combination with 5 Fu,CTX and PDD,and in contrast with 5 Fu,CTX and PDD alone,the experiments were carried out on mouse transplanted Heps and EC.

方法从银杏叶中分离纯化聚戊烯醇，分别与氟脲嘧啶(5 Fu)、环磷酰胺和顺铂联合应用，对移植性Heps和EC荷瘤小鼠进行抑瘤实验，并与 5 Fu、CTX和PDD单独用药比较。

Using heptachlor epoxide as interal standard, the linearity of 28 pesticides were good with 〓 in 0.99～1. 000, except phosphamdon with 〓 at 0.963. The RSD for most pesticide were below 10％.

采用该方法，以环氧七氯为内标，29种农药中28种农药的线性关系良好，〓在0.99～1.000之间（磷胺的〓为0.963），大部分农药的RSD0％。

Among the special nine pollutants, however, eight of them, including Hexachlorobenzene, N-Nitrosodi-N-propylamine, 3,3-dichlorobenzidine, 2,4,6-trichlorophenol, 2,3,4,5,6-pentachlorophenol, indeno (1,2,3-cd) pyrene, 4,4'-DDT and Heptachlor were in need of concern while another chemical: dibenzanthracene be of special concern. The sources of these chemicals were discussed and some control strategies were suggested based on the risk assessment.

结果表明，有18种有机污染物超过了USEPA的标准浓度要求，其中9种物质具有一定的生态风险，其中六氯苯、N-亚硝基二正丙胺、3，3'-二氯联苯胺、2，4，6-三氯酚、五氯酚、茚并(1，2，3-cd)芘、4，4'-滴滴涕、七氯在内的8种化合物具有一定的风险，而多环芳烃二苯并蒽需要引起更高警惕；在此基础上探讨了这些化合物的来源及作用，并提出了相应的防治建议。
