心脏收缩的

Masseter "strongest;" 975 pounds for 2 seconds; gluteus maximus and quadriceps strongest if leverage not included

心肌和平滑肌的收缩不由意识控制且为生存所必需，例如心脏的收缩或是肠胃道的蠕动等。

In the first 2-3 hours there is always a strengthening of contraction, while after 5-10 hours, when the heart gives much feebler contraction due to exhaustion, this beneficial effect of phosphatide tends to disappear.

二葡萄糖在灌流液中的作用视室温与离体时间而定。在较高室温长期灌流而衰竭的心脏，葡萄糖是必要的，它可以维持心肌收缩并被心肌所消耗。如心脏离体时间较短，室温较低，则葡萄糖并非必需。

At 30mg/kg there is the best effective and induced the heart rate to be reduced by12.8%, systolic pressure and diastolic pressure by 12.5% and 16.3%.At the same time the cardiac max contractility and relaxtion have also been reduced by 12.5% and 16.3%.

在30mg/kg剂量时达到最佳作用效果，可使心率降低12.8%，动脉收缩压和舒张压各降低12.5%和16.3%，同时心肌最大收缩和舒张速率也分别降低了34.3%和39.4%，明显降低了高血压对心脏的压力。2、Rb1能够剂量依赖的降低L-NNA导致的慢性高血压模型的血压，并且对高血压心肌舒张功能障碍起到保护作用。

The results show that the responsiveness of the hypertrophied heart to FRCRSFa and E-4031 had no significant change to the healthy heart though the density of 〓 is increased and the cardiac function is decreased.

FRCRSFa对心肌肥厚大鼠离体灌流心脏的收缩与舒张功能有抑制作用；而E-4301可增强其收缩与舒张功能，上述作用与正常心肌比较，亦无明显差异。

The patient's vital sign was stable intraoperative and cardiologist was consulted after he was transferred to ward. The 12 lead ECG showed complete AV block and diffuse ST-segment elevation. The echocardiogram showed LV global hypokinesia with impaired contractility, ejection fraction 37% and dilated right heart.

手术中病患的生命徵象都稳定，术后回到病房即照会心脏科医师。12导程心电图显示为完全性房室阻断及广泛的ST升高；心脏超音波检查发现左心室跳动不良、收缩力不好，射出率只有37%，右心有扩大的现象。

Cases with renal transplantation were performed with dynamic state CDFIin Ultrasound Dept. of Nan fang Hospital from April, 2005 to October, 2006. Theexamine time is respectively after operation in three days, seven days, one month andthree months. Before operation examine the condition of uropoiesis function such as apair of kidney, ureter, bladder and cardiac function. After operation reexamine thecondition of cardiac function once again, and examine TK detailed and completely:First, using two-dimensional imaging to observe the shape and the volume of the TK.Secondly, using Color Doppler to observe the renal artery and each artery inside theTK. Finally, using pulsed Doppler to measure the peak systolic velocity, enddiastolic velocity and resistance index.

对南方医科大学南方医院超声诊断科自2005年4月～2006年10月对152例同种异体肾移植患者进行动态CDFI监测，超声检查时间分别为术前与术后3d、术后7d、1个月及术后3个月，术前超声检查双肾、输尿管、膀胱等泌尿系功能情况及心脏功能情况，肾移植术后再次对心脏功能情况进行跟踪复查，并对移植肾进行详尽检查：先用二维超声观察移植肾的形态、大小，随后应用CDFI观察移植肾动脉及肾内各级动脉的血流充盈情况，最后用脉冲式多普勒测量收缩期峰值流速、舒张末期流速、阻力指数。

Endothelin-1 (ET-1) is a potent vasoconstrictive and mitogenitic peptide generated by all types of cardiovascular cells. It plays an important role in many physiologic and pathophysiological processes such as heart development, heart failure, cardiac hypertrophy, arrhythmia and so on.

内皮素-1(endothelin-1 ， ET-1)是目前已知最强烈的血管收缩物质之一，主要分布于心血管系统，参与了心脏发育、心肌肥厚和心律失常等心脏生理和病理生理过程。

A narrowing or constricting, especially of the aorta or of a blood vessel.

心脏各室的收缩，收缩时把血液压入大动脉和肺动脉。

Unlike other heart-failure deices, the Optimizer works by strengthening the pumping force of the heart.

和其他心衰治疗装置不同，它是通过强化心脏的收缩能力来起效的，而不是心脏的节律。

Furthermore, allatostatins inhibit contraction of muscles in heart, dorsal vessel and oviducts.

AS能抑制前肠、中肠、后肠肌肉的收缩，导致昆虫厌食、生长延迟、死亡率上升等现象，此外，还能抑制心脏、背血管和输卵管等器官中肌肉的收缩。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
