节律发生

目的：探讨N甲基D天门冬氨酸（NMDA）和非NMDA类受体在基本呼吸节律发生和调节中的可能作用。

Aim : To study the possible role of the NMDA and non NMDA receptor on the generation and modulation of basic respiratory rhythm .

每天的工作任务、上下班的交通、社交活动和孩子的日程安排经常支配了我们的时间&不可避免地与人体苏醒和睡眠的生物周期节律发生冲突。

Workday demands , commuting , social events and kids ' schedules frequently dominate & inevitably clashing with the body 's circadian rhythms of waking and sleeping .

新近文献报道，胃肠节律的发生起源于胃肠道内的Cajal间质细胞（Interstitialcellsofcajal，ICCs）。

Recent literature reported that the pacemaker of GI tract originated from the interstitial cells of Cajal ( ICCs ) .

结果：FD患者胃电节律紊乱发生在胃体部为42.11%，胃窦部为63.16%；

Results : The gastric myoelectrical dysrhythmia was found in 42.11 % of the cases in the gastric body and in 63.16 % in the gastric antrum of functional dyspepsia .

本文尚就呼吸节律的发生机制做了讨论。

In addition , the mechanism of genesis of respiratory rhythm was discussed .

结果在吗啡作用下海马神经元自发放电节律会发生转变，纳络酮可以逆转这种转变，共观察到4种转变形式。

Results Changes of the rhythm pattern of spontaneous discharge of hippocampal neurons induced by morphine were found .

在体温节律的发生和维持上，视交叉上核可能是皮肤温度昼夜节律的中枢起搏器，而深部体温的昼夜变化主要受松果体的支配。

In terms of initiation and daily running of the rhythmic oscillation , pineal is probably the central clock of the skin temperature rhythm , while SCN mainly controls the core temperature rhythm .

但有关ICCs节律电活动发生机制目前尚未完全清楚[4]，严重影响了临床对许多类型的胃肠运动障碍性疾病的治疗。

However , the mechanism of generation of the rhythmic electric activity is not fully known , which seriously hinders the treatment and therapy to multiple GI dynamic diseases in clinic .

发育学以及基因突变技术研究表明：c-kit基因删除或自发性c-kit突变W/Wv小鼠以及用抗Kit抗体使Kit失活，均能导致ICC的发育受阻，其胃肠节律蠕动会发生紊乱或胃肠节律运动消失[1~5]。

Auxology and gene mutation techniques have documented that abnormal ICC development occurred in c-kit gene ablation or spontaneous mutation w / wv mice , or by inactivation of Kit with anti-Kit antibody , therefore lead to the GI tract disorder of rhythmic peristalsis or rhythm disappearance .

动物实验和对人体肿瘤的研究均表明生物节律参与肿瘤的发生、发展。

Studies of animal models and human tumor samples have revealed that the disruption of circadian rhythms is an important endogenous factor that contributes to mammalian cancer development .

实验结果表明，此系统可较好地模拟生物特性，完成双关节耦合节律性运动的发生，并能通过较为简单的结构实现运动的高层调节以及生物反射作用的模拟。

Experimental results show that this system can accomplish double coupling joints rhythm movements simulating biological characteristics , and can achieve movements changing , high-level regulation of the movements and reflection simulation with a relatively simple structure .
