Conclusions Denticulate ligament was a mark and could be used to identify and localize the spinal nerve anterior and posterior roots in the SPR or SAR, especially for the cervical nerve roots.

结论在选择性脊神经根切断术中，齿状韧带可作为一标志，脊神经前、后根可通过齿状韧带加以鉴别和定位，特别在颈部。

Results: The ventral roots lay in front of the denticulate ligament, while the dorsal one behind it.

结果：臂丛前后根之间有齿状韧带相间隔；

Methods The denticulate ligament was observed and measured on 30 adult specimens.

方法对30例（60例）成人尸体的齿状韧带进行了解剖学观测和测量。

CT scans showed bilateral symmetrical hypodensity foci in lenticular ( 5/ 7), head of caudate nucleus ( 4/ 7), thalamus ( 2/ 7) and dentate nucleus ( 1/ 7).

双侧豆状棱（5/7）、尾状棱头部（4/7）、丘脑（2/7）及齿状核（1/7）对称性低密度区和与年龄不相符的脑萎缩。

Conclusion In the early stage, MSA is shown the degeneration of neuron is mild, and the lesion of axon is the main pathological changes. The PV (+) neuron in the dentate nucleus may due to the cell protective reaction.

结论MSA早期小脑的病变是以轴索病变为主而神经元变性则较轻，并且在齿状核出现的PV（+）神经元可能是一种细胞保护性反应。

From 32 rhesus monkeys the vermis cerebelli and the portion containing the dentate nucleus were fixed in 10% formalin. The animals of both sexes were divided into 4 age groups according to their dental status.

用狝猴32只，分雌雄两批，按齿序情况分为4个年龄组。取小脑蚓体及含齿状核的部分，用10%福尔马林固定，作石蜡切片及少量冰冻切片。

Cerebellar FN and DN ( Dentate Nucleus) were stimulated electrically for 1 hr, one day, 4 days and 7 days before MCAo R ( 1.5 hr/ 24 hr).

于缺血前1、4、7天分别刺激小脑顶核、齿状核1hr。
