By superfusion of ET-1,the hypoxia-induced decrease in RPF was remarkably potentiated and the occurrence of pacemaker arrest was shifted to an earlier time. The h3,poxia-induced effects could be effectively attenuated after pretreatment with BQ-123,implying the role of endogenous ET-1 release in hypoxia-induced effects.

ET-1可显著加重缺氧所致的RPF降低，使起搏细胞停跳时间前移；而以ET*受体阻断剂BQ-123预处理窦房结标本后，则能有效地缓解缺氧对起搏细胞的效应，提示内源性ET-1的释放在缺氧效应中的作用。

Primary study on the reconstruction of suprarenal abdominal aorta of pig with aortic bypass was done.

建立在小猪腹腔动脉开口以上阻断腹主动脉1小时和辅助主动脉转流的模型，观察术后动物出现并发症及组织病理学的改变，研究辅助主动脉转流重建肾上腹主动脉的效果。

Methods A pig ischemic model was established by cross-clamping of the abdominal aorta above the celiac artery for 1 hour, and aortic bypass was used at the same time. The survival rate and complications of the animals were observed after operation. Pathological changes of the spinal cord were also observed on month after operation. Primary study on the reconstruction of suprarenal abdominal aorta of pig with aortic bypass was done.

AIM: To isolate bioactive secondary metabolites from the fruits of Schisandra rebriflora Rehd. et. Wils and study their effects on HIV-1 infectivity. METHODS: Inhibition of syncytia formation, HIV-1 reverse transcriptase and protease, protection of HIV-1 infected cells, level of HIV-1 p24 antigen,blockage of fusion were detected. RESULTS: A lignan compound, named rubrifloralignan A, was first isolated as a natural product with modest inhibition effects on syncytium formation and HIV- 1 replication and could protect HIV-1 infected cells with weak inhibition effects on fusion and RT, but it showed no effects on the replication of HIV-1 chronic H9 and PR. CONCLUSION: Rubrifloralignan A is an efficient anti-HIV-1 product with effect on early stage of HIV-1 replication.

目的：从红花五味子果实中寻找活性代谢产物，研究其抗HIV—1活性和作用机制方法：通过合胞体抑制、HIV-1感染细胞保护、HIV—1p24抗原测定、融合阻断、逆转录酶和蛋白酶活性分析等实验，检测分离化合物的抗HIV—1活性并探讨其作用机制一结果：红花五味子甲素能够抑制病毒诱导的合胞体形成，保护病毒感染细胞，抑制病毒在细胞内的复制对HIV-1感染细胞与正常CD4^＋细胞间的融合，逆转录酶活性有一定的抑制作用但是红花五味子甲素不抑制病毒在慢性感染细胞中的复制，也不抑制蛋白酶的活性、结论：首次从天然产物中分离得到红花五味子甲素，它对HIV—1病毒复制早期具有抑制作用

Results The HSV infected cell culture system we established stable for utilization: Cellular damage and abnormal growth were not found in Hep-2 cells cultured with SDS at 10%×2-3×10-1(1.25mg/ml).The Hep-2 cells mainly became swelling and falling off and few of them formed syncytium after infected by HSV. The CPE occurred time and scale of CPE depended on multiplicity of infectionof HSV.SDS inhibited HSV yield with the manner of dosage dependent.

在 HSV 感染的 Hep-2 细胞培养系统中分别观察 SDS 对 Hep-2 细胞的毒性作用、SDS 对 HSV 致 Hep-2 细胞病变的影响、SDS 对 HSV 空斑形成的阻断效应、四唑盐(diphenyl tretrazolium bromide，MTT)比色试验检测不同浓度 SDS 抗 HSV 效应、以及 SDS 和阿昔洛韦(Aciclovir， ACV)抗HSV 效应的比较。

This study was designed to test the hypothesis that blockade of central nervous system adenosine receptors may explain the beneficial effect of caffeine on fatigue.

此研究的目的是验证下述假设：咖啡因对解除疲劳的正面作用是通过阻断中枢神经系统的腺苷受体实现的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
