The morphous of fetal rat cortical neuron is almost intact.Discussion:1 .Establishment of AD cellular modelSince Yankner 1990 first confirmed toxic effect of synthetic Aβ on hippocamp neuron in rats,cellular model was broadly used for research of mechanism of neurotoxicity due to advantages of simplification and utility.

讨论： 1.AD细胞模型的制作自从1990年Yankner首先证实合成的Aβ对培养大鼠海马神经元有毒性作用以来，体外培养的细胞模型以其简便、实用的优点被广泛用来研究Aβ的神经毒性机制。

Brain injury caused apoptosis of neurocytes which reached peak values 72 and 24 h after injury respectively in frontal cortex and hippocamp CA1 region around the injury sites of rats.

颅脑损伤可导致损伤周边区大脑额皮质及海马CA1区神经细胞凋亡，凋亡高峰时间分别为损伤后72和24h。

Objective To study the effects of Si-ni Powder, Xiao-yao Powder and Si-junzi Decoction on chronic unpredictable mild stress model's BDNF and CREB gene expression changes in hippocamp of rat.

目的：探讨慢性应激肝郁模型大鼠海马BDNF、CREB基因表达及疏肝、疏肝健脾与健脾三种方剂的效应。

In the middle of 90's, it has been found that hydrogen sulfide (H2S) is one of the metabolite of aminothiopropionic acid, which might regulate the function of nervous system, especially hippocamp, and might regulation the tension of digestive tube and vascular, which has the similar biological function with NO and CO. Recently, major concern has emerged that H2S might be a novel endogenous agent during the patho-physiological reactions during endotoxic shock. Until now, the role of H2S playing in endotoxic shock is still quite confusing.

九十年代中叶，人们发现在体内半胱氨酸代谢过程中生成小分子气体硫化氢(hydrogen sulfide，H2S)，对神经系统特别是海马功能具有调节作用，且可以调节消化道和血管平滑肌张力，其生物学作用类似NO和CO.H2S作为内毒素休克时一系列病理生理反应中的一种新的内源性介质，已开始受到人们的重视。

Objective To investigate the expression of α7-nAChR on rat hippocampal astrocytes in vivo and in vitro.

目的 探讨α7-nAChR亚基在体内、体外海马星形胶质细胞上的表达。

These showed that the activity of hippocampal neuronal networks is sensitive to the temperature.
