Results:①Excitation of the NVM by L-glut amate,injection of substance P into the nucleus dorsomedialis, n ucleus paraventricularis or rostral ventrolateral medulla,all induce d pressor responses.②NVM pressor responses could be attenuated by preinjection of ［D-Pro2,D-Phe7,D-Trp9］-SP (DPDPDT,a substance P antagonist)bilate rally into the NDM,NPV or RVL,but preinjection of atropine into the RVL had no s uch effect.

结果 ：①L-谷氨酸兴奋NVM、P物质注入背内侧核室旁核或延髓头端腹外侧区均引起升压反应；②NVM升压反应可被双侧NDM、NPV或RVL内预先注射［D- Pro2，D-Phe7，D-Trp9］-P物质衰减，但RVL内注射阿托品无此效应；③酚妥拉明i.v。

Pressor effects of central amygdaloid nucleus are mediated by IL-1β in hypothalamic paraventricular nucleus or arcurate nucleus.

下丘脑室旁核及弓状核内的IL-1β均介导兴奋中央杏仁核诱发的升压反应。

The machine adopts computerised control system,could complete functions of auto needle position,auto thread cutting,and auto pressor foot lift.

该产品采用微机控制系统，能实现自动停针、自动剪线、自动拨线和自动抬压脚功能。

The effects of electroacupuncture on the pressor response and reversible myocardial dysfunction induced by application of bradykinin on the gallbladder were studied in cats anesthetized with α-chloralose. The cardiovascular responses evoked by application of BK included a pressor response, an increase of LVP and its dP/dtmax, tachycardia and a decrease of local wall motion of the left ventricle with a supplying branch of the left anterior descending coronary artery ligated beforehand.

在α-氯醛糖麻醉的猫上，结扎左心室冠状动脉前降支一小分支，对动物胆囊浆膜面予以缓激肽，可反射性地诱发血压、左心室内压升高、±dP/dtmax增大、心率加快，同时用超声单晶片声纳测微系统记录局部心壁运动，发现BK可以反射性地引起LAD小分支远端所支配的心肌运动功能减弱。

In addition, the decerebration significantly diminished the peak pressor effects on PRN stimulation.

此外，去大脑手术会显著的减少由电刺激旁内核所引起的升压反应。

Methods:Interbrain microinjection of drugscombined with observation of changes in arterial pressor and heart rate were used.Results:(1)Corticotropin releasing factoror substance Pmicroinjectioninto the SL can induce pressor response.

本实验室的一系列研究结果证明，控制情感和压力的神经升压环路中，AC是最重要的，AC通过CRF -或SP -能神经元与其它的神经核团有广泛的联系［1—4］。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

On the normotensive rat, bilateral microinjection of L-arginine (16 n mol/0.1 ul/site), a precursor of nitric oxide into the rVLM, caused a decrease in BP, HR and the pressor response induced by the dPAG stimulation, while microinjection of NG-methyl-Larginine (L-NMMA, 16 n mol/0.1 ul/site), a blockade for NO to form, into the rVLM bilaterally, caused an increase in BP, HR and the pressor response induced by the dPAG stimulation. There was no effect of both drugs mentioned above on the tachycardiac response induced by the dPAG stimulation.

五、在正常血压大鼠，于双侧rVLM微量注射一氧化氮前体(16nmol/0.1μl/site)可引起BP降低、HR减慢、以及电刺激dPAG诱发的防御性升压反应减弱；而于同区微量注射生成一氧化氮的拮抗剂N〓-甲基-L-精氨酸(16nmol/0.1μl/site)则可引起BP升高、HR加快、以及电刺激dPAG诱发的防御性升压反应增强；而上述两药对电刺激dPAG诱发的防御性加快心率反应均无明显作用。

Benzoate (400 mg/kg) or creatinine (400 mg/kg), two inhibitors of DAAO, blocked D-NNA-induced pressor responses in rats. Furthermore, the addition of the pure DAAO significantly potentiates L-NNA production rate in kidney homogenates by approximately 2-folds. The in vivo and in vitro results suggested that DAAO plays an essential role in the pressor responses elicited by D-NNA.

体内实验显示，DAAO的选择性抑制剂苯甲酸钠(400mg/kg)或肌酐(400mg/kg)均可在不同程度上抑制D-NNA升压作用，进一步研究发现，肾脏或肝脏DAAO酶液在外加DAAO后可提高D-NNA的手性转化约2倍，表明DAAO对于D-NNA在体内的手性转化是必需的。

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。
