窦房的

Objective To observe the location, the morphous and cell component of normal adult sinuatrial node, and expresion of Cx43, Cx40 in it.

目的观察正常成人心脏窦房结的细胞构筑及连接蛋白43、40（connexin43、40，Cx43、Cx40）的表达和分布情况。

Each electrical signal begins in a group of cells called the sinus node, or sinoatrial node.

电信号是由一个称为&窦房结&的细胞群发出的。

The isolation and cultrue of ripe procine sinoatrial node pacemaker cell need a new and dependable cell cultured technique.

成熟猪窦房结起搏细胞的分离和培养需要一套全新可靠的细胞培养技术。

The normal heartbeat is synchronised by a collection of muscle fibres in the upper right chamber of the heart called the sinoatrial node.

正常的心跳是花样由收集了肌肉纤维在右上角商会的心脏，称为窦房结。

To investigate the relationship between action potential parameters and age by comparing the action potentials recorded from sinoatrial node of different age group in rabbits.

观察不同年龄组兔窦房结组织不同部位的动作电位形态及主要参数的变化并寻找其规律。

In a normal heart rhythm, the impulse generated by the sinoatrial node spreads through the heart and causes contraction of the heart muscle and pumping of blood.

在正常的心律时，由窦房结产生的脉冲传播通过心脏，并导致心肌收缩和泵送血液。

An artificial pacemaker works by restoring the function of a faulty sinoatrial node, the heart's natural pacemaker.

人工心率调整器的作用是使紊乱的心脏天然心率调整器窦房结恢复正常功能。

The signals that make the heart's muscle fibres contract come from the sinoatrial node, which is the natural pacemaker of the heart.

驱使心脏肌肉纤维收缩的信号来自于窦房结，它是心脏天然的起搏器。

The results indicate that without the influence of nervous and humoral factors, the spontaneous heart rate would also become slower as the rabbit grew older, which is due to the decrease of spontaneous depolarized rate of phase 4 in SN cells.

实验结果提示，离体心脏和窦房结标本在没有神经体液因素影响的情况下也有随周龄增长而自律性变慢的现象。

METHODSEffects of reducing heart rate of Tet were maintained in isolated right atrium and pithed rats. Modification on action potentials AP of SAN cells and L-type calcium current ICa-L by Tet were recorded by means of standard microelectrode and patch-clamp whole cell recording techniques.

方法在离体右心房标本及毁脊髓大鼠模型观察粉防己碱减慢心率的作用，用标准微电极及膜片箝全细胞记录技术观察Tet对窦房结动作电位及L型钙电流ICa-L的影响。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
