dentate nucleus

A study on microvasculature of dentate nucleus

齿状核微血管构筑的研究

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。

TGF-β_1 immunoreactivity can be seen in the cytoplasm and processes of medulla oblongata lateral reticular nuclear, cerebellar dentate nucleus and inferior olivary nucleus neuron.

在延髓外侧网状核、小脑齿状核可见明显阳性的TGF-β1免疫反应阳性的神经元，下橄榄核可见弱阳性细胞分布；

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。

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。

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).
