心室的

How it works: Unlike the Jarvik 7, the JaMk 2000 does not replace the natural heart. Instead, the tiny pump -- about the size of a C cell battery -- is inserted in the organ's left ventricle, where it boosts blood flow.

工作原理与加维科7号不同的是，加维科zop号并不取代病人自己的心脏，而是将c电池大小的小型水泵装人左心室，在那里它可刺激血液的流动。

The finger at the left is holding a markedly thickened right ventricular free wall below the tricuspid valve, and the finger at the right is holding the interventricular septum.

左边手指提着的是明显变厚的位于三尖瓣下的游离心室壁，而右边手指提着的是室间隔。

There are considerable variations of calcium channels across the canie left ventricular wall,which may be the molecular basis of the distribution of ICa L and ICa T, and may play an important part in the occurence and drug treatment of reentry arrhythmias.

最近又有研究发现，L型钙通道和T型钙通道在犬的左心室也存在明显的异质性分布，并认为也是形成左室电异质性的一个重要因素［4］，但构成左室ICa L，ICa T异质性的分子基础尚不甚明确。

Nighty rats were randomly divided into the groups of control, myocardial infarction and doxycycline, which were given orally 48 hours before and 48 hours after MI with 30mg/Kg per day. Protein and mRNA extraction was done on left ventricular samples containing scar and myocardium together. Samples were assayed from 1 day to 4 weeks post-Mi. The activity of MMPs was measured by zymography and collagen amount by the method of chloramine T, the ratio of II III collagen was assessed by immunohistochemical stain. Protein and mRNA of MMP-2, 9, TIMP-1 were determined by Western-Blot and RT-PCR.

分为对照组、心梗组和治疗组(D组，术前两天至术后两天，口服Doxycycline，30mg／kg／天)，分别于术后第一天、术后一周、术后两周、术后四周取心肌组织，采用免疫组化测定胶原含量和Ⅰ／Ⅲ胶原比例，酶谱法测定心梗后MMP-2，9活性蛋白的表达规律，Western Blotting进一步确定酶谱法中所消化条带蛋白的属性，逆转录-聚合链反应法测定心梗后MMP-2，9和TIMP-1的mRNA的变化规律，运用Acuson Sequoia 512超声心动图机分别测定心梗组、治疗组在两周和四周时左室前壁、后壁厚度以及左心室舒张末内径和左室射血分数。

Aim: To determine whether activation of κ-opioid receptor with U50,4 88 H, a selective κ-opioid receptor agonist, produces any changes in electrical u ncoupling during prolonged ischemia and whether these changes in electrical unco upling is associated with the cardioprotection induced by κ-opioid receptor ac tivation, and to explore the possible mechanism.

测量指标：以分光光度计在490nm波长下测定氯化三苯基四氯唑与活细胞反应的产物formazan含量的方法测定心肌细胞活性、测定冠脉流出液中乳酸脱氢酶的含量以及心室内压；②全心停灌70min，应用四电极法观察不同浓度U50，488H、nor-BNI和5-HD对缺血期间心肌整体阻抗和电脱耦联参数(电脱耦联时间、平台时间、电脱耦联最大速率和阻抗倍数)的影响。

One of most possible cause of sudden death may be fibrotic quiver of left ventricle.

猝死的常见的原因是心脏的左心室发生了无规则的纤维性颤动。

It suggests that hypertensive left ventricular hypertrophy and hypertensive arteriolosclerosis in heart and brain may be the same pathological base which causes myocardial infarction complicating with cerebral infarction, and that hypotension is an important inducing factor causing myocardial infarction complicating with cerebral infarction.

提示高血压所致的左心室肥大和心脑小血管的动脉硬化改变可能是心脑梗塞并发的共同病理基础，而低血压则是引起心脑梗塞并发的一个重要诱因。

Methods The experimental arrhythmia models were induced with barium chloride (BaCl2),uabaina and aconitine in rats and cobayaes.The incidence rate and mortality rate of arrhythmia,the emergence time and the duration of arrhythmia induced with BaCl2 were recorded in rats pretreated with CASI (in dosages of 25,50, and 100 mg·kg-1 sublingual vein injection).At the same time,the dosages of uabaina and aconitine were observed when the ventricular premature contraction,ventricular tachycardia,ventricular fibrillation and cardiac asystole were appeard in rats and cobayaes pretreated with CASI (in dosages of 25,50, and 100 mg·kg-1 sublingual vein injection).

制备氯化钡(BaCl2)、哇巴因及乌头碱诱导的大鼠及豚鼠实验性心律失常模型，CASI按25、50、100 mg·kg-1分为3个剂量组，舌下静脉给药1次，不给CASI作为对照组，记录大鼠给BaCl2后心律失常的发生率、出现时间、持续时间及动物的死亡率；观察豚鼠及大鼠出现室性早搏、室性心动过速、心室颤动及心脏停搏时哇巴因及乌头碱的用量。

Indeed, by increasing the pressure in the right atrium and in the left ventricle with respect to extrathoracic vascular beds, positive-pressure ventilation affects the pressure gradients for both systemic venous return and left-ventricular ejection increase; Fig.

实际上，机械正压通气引起的右心房、左心室内的压力增加，这样和胸腔外血管床形成一定的压力梯度，此压力梯度会影响心肺两系统的静脉回流及左心射血（增加，见图1）。

Objective This study is to observe the effect of carvedilol on Cx43 of infarcted rabbits and its relationship with ventricular arrhythmia.

目的卡维地洛是一种新型的抗心律失常药物，对β1、β2、α1受体都有阻滞作用，而Cx43是心室肌心电传导的基础，本组观察卡维地洛对心肌梗死边缘区Cx43分布的影响及与室性心律失常的关系。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
