肌张力减低

Result Rabbits′ neurologic symptoms (hemiparalysis,convulsion and hypotonia) and death were observed after embolization.Thrombogenesis was present and the entire cross sections of blood vessels could easily be embolized.

结果 国产HMs栓塞后能引起兔偏瘫、抽搐、肌张力减低及死亡，可诱发血栓形成，易阻塞血管的全截面。

Rapid eye movement sleep consists of a dreaming state in which there is activation of the cortical and hippocampal electroencephalogram, rapid eye movements, and loss of muscle tone. Although REM sleep was discovered more than 50 years ago, the neuronal circuits responsible for switching between REM and non-REM sleep remain poorly understood. Here we propose a brainstem flip-flop switch, consisting of mutually inhibitory REM-off and REM-on areas in the mesopontine tegmentum. Each side contains GABA (gamma-aminobutyric acid)-ergic neurons that heavily innervate the other.

快动眼睡眠是一个包括有皮层和海马脑电活动的睡梦状态，可见眼球的快速运动和肌张力减低，尽管快动眼睡眠已经被发现50余年了，对其与非快动眼睡眠之间的神经回路却知之甚少，我们用脑干触发转换器，包括脑桥背盖区一个互相抑制的快动眼-关、快动眼-开区域，每侧均包含高度互相支配gamma氨基丁酸能神经元。

Results Most of the rabbits can live for a long-term after the middle third of the superior sagittal sinus and its veins ligation with symptoms and signs of neural system such as hemiplegia and hypomyotonia.

结果 上矢状窦中1/3及其回流静脉结扎可引起家兔偏瘫、肌张力减低等神经功能障碍，但大多能长期存活。
