The dose-response curve of histamine was shifted parallely to the right. pA2 was 9.34±0.61. The guinea-pigs were effectively reduced the rate of histamine induced death, decreased reaction extent of shock (P＜0.01) and prolonged latency period of shock (P＜0.05) by orally administered cetirizine ranged from 0.1, 0.2 and 0.4 mg.kg-1. The capillary permeability to intracutaneous injection of histamine was potently inhibited by orally administered cetirizine ranged from 0.0625 to 0.25 mg.kg-1 in mice, blue area obviously decreased (P＜0.01), and dose-response curve existed obviously. In which the effect of these dosage groups were superior to the group of chlorphenamine.

结果：西替利嗪3×10-8～3×10-7mol.L-1可剂量依赖性地对抗组胺引起的肠肌收缩，使组胺的量效曲线平行右移，pA2为9.34 ± s 0.61，西替利嗪0.1，0.2及0.4 mg.kg-1口服给药时，能明显减轻豚鼠静脉注射组胺所致休克反应的严重程度(P＜0.01)，并可延长豚鼠惊厥反应的潜伏期及降低死亡率(P＜0.05)，西替利嗪0.0625～0.25 mg.kg-1口服给药可显著对抗组胺引起的小鼠皮肤血管通透性的增高，使蓝染面积显著缩小(P＜0.01)，且存在明显的量效关系，3个剂量组的作用均优于氯苯那敏组。

Both ACEI with or without sulfhydryl groups could prevent the H2O2 induced decrease in contraction responses to PE in intact aortic rings. The increase of NO and activation of HO-1 might be involved in the mechanism.

含有和不含筑基的ACEI均具有对抗H2O2引起的血管收缩功能下降的作用，其主要机制可能是通过引起NO产生增加和诱导HO-1而实现的。

With the continuous infusion of remifentanil at the rate of 10μg·kg-1·h-1, group S was inhaled sevoflurane of 0.5～1MAC and group P was infused with propofol of 4～6 mg·kg-1·h-1 Hemodynamic parameters (HR、MAP、CO、SV、SVR、ACI、LCWI)were measured with Bioz.com CardioDynamics at different times before and after pneumoperitoneum. At the end of surgery, all the anesthetics were stopped and the awakening condition was observed.

在持续输注瑞芬太尼10μg·kg-1·h-1的基础上，S组复合吸入0.5～1MAC的七氟烷，P组复合输注4～6mg·kg-1·h-1的异丙酚，采用Bioz.com监测仪测定气腹前后各时点的血流动力学指标，包括心率、平均动脉压、心输出量、每搏输出量、外周血管阻力、心肌收缩指数、左室做功指数。

Renal glomerulus is a exceptive capillary mass, its mesangial cell is similar with vascular smooth muscle in anatomy, origin, histochemistry, and constriction function, etc.

肾小球是一个特殊的微血管结构，其中的系膜细胞在起源，解剖、组化和收缩功能等方面与血管平滑肌十分接近，而且肾小动脉硬化与冠状动脉粥样硬化的病理改变亦有相似之处，因此考虑两者的发病机制可能类同。

Xinmao digital ultra light energy weight-reducing instrument can produce ultra light energy which is of strong penetrability into muscle for 12.5cm. At the first few minutes the combustion technology of light wave makes epidermis and under-epidermis tissue more fluid, and strengthens the exchange of body fluid activity and changes the strucrure of tissue density , veins and lymph structure ,increase the content of nutrition in the blood rapidly.despel remnant liquid and metabolized substance in the body at the same time.By treating hypodermis,thning hypodermal tissue fat and fat resolving enzyme mediating device, it can promote the softening, shrinking, and resolving the fat in deep so as to burn it.

数码爆脂减肥仪所产生超光能量有深层次穿透力，能深入肌肉12.5cm，光波的燃烧技术在最开始的几分钟使表皮及皮下组织更趋流动性，承受后急速加强体液活动资质及改变组织密度组织结构，对不同动、静脉血管、淋巴结构的连续缩放减压，可迅速提升营养成份在血液中的含量，同时消除体内残留液体及代谢产物，通过治疗真皮及皮下组织变薄，脂肪及脂肪分解酶受体获调解器，可将深部的脂肪加速促进软化、收缩、分解燃烧掉，。

Time to ischemic stroke and stroke in the same territory of the stenotic essel was compared in patients grouped by mean systolic blood pressure and mean diastolic blood pressure during the study.

进一步分析的是以病变的严重程度和狭窄的位置为根据。在试验过程中，把病人按照平均收缩压和平均舒张压进行分组，对比缺血性中风和狭窄血管相关区域的中风的时间。

Classically, Ang Ⅱ is well known to cause potent increases in systemic and local blood pressure via its vasoconstrictive effect, to influence renal tubules to retain sodium and water, and to stimulate aldosterone release from the adrenal gland.

众所周知，Ang Ⅱ通过它的血管收缩效应导致系统和局部的血压增高并影响肾小管的钠水潴留以及刺激肾上腺的醛固酮释放。

The information can also transfer via a signal transduction pathway, therefore ET-1 can cooperate with some growth factors such as bFGF, TGF-β and PDGF. ET-1 is not only a potent vasoconstrictive peptide, but also a strong cellular division factor. It is an important regulator to intimal hyperplasia.

因为ET-1不仅是最强的血管收缩物质，而且还具有强烈的细胞分裂作用，所以，ET-1是内膜增生的重要调节因子，但目前对于静脉移植术后不同时期ET-1的动态变化及其与内膜增生相互关系的研究尚不多见。

L-1 (10-7mol . L-1) noradrenaline induced contraction of rat aortic strip was taken as criterion. Compound I5 was shown to be a potent potassium channel activator. Compound II8 exhibited calcium antagonistic activity and showed potent vasodilating activity.

引起的大鼠主动脉条收缩有较好的抑制作用，其中化合物 I5的钾离子开放活性与尼可地尔相当，化合物 II8显示有钙离子通道拮抗活性，并有较强的扩血管活性。

In the previous studies the constituents from Cinnamomum philippinense reported to have the biological activities such as antiplatelet aggregation, vasorelaxation, cardiac muscle contraction, antioxidation and free radical scavenger activities etc. Furthermore, MA-1 a ligan isolated from Cinnamomum philippinense is considered to be an important prophylaxis to treat ischemic stroke due to its antioxidation and free-radical scavenger activities. The present project aims to develop MA-1 as a pre-medicine to treat ischemic stroke.

在过去的研究中，发现菲律宾樟树所含的成分对心脑血管相关的活性诸如抑制血小板凝集、血管松弛、影响心肌收缩、抗氧化、自由基清除等具有不错的活性作用，而由菲律宾樟树所分离得到的一种新木质酚MA-1，具有抗氧化作用且是自由基捕捉剂，获选为开发成缺血性中风之预防与治疗先导药物。

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。
