海马

MSG could insult the functions and structures of specific brain areas of adult mice through blood-brain barrier. The ability of discrimination learning in Y-maze was affected markedly, especially in 4. 0g/kg MSG group, meanwhile, dark pyknotic and loss of neurons were shown in arcuate nucleus of hypothalamus, but not in hippocampus. Consistent changes occured in mitochondrial membrane protein bound 〓 by 〓-fluoresent probe, i.

MSG可以透过成年小鼠血脑屏障产生神经毒性作用。4.0g/kg MSG对小鼠空间分辨学习能力的损伤程度较2.5g/kg MSG更为明显，同时下丘脑弓状核神经元出现核固缩及神经元数目明显减少，相同处理未引起海马神经元的明显变化。

The research aimed to observe the inclusion body in pyramidale cytoplasm in hippocampus of cerebral cortex in shepherd dog with rabies.

观察患狂犬病的牧羊犬大脑皮层海马的锥体细胞浆内的包涵体。

The results showed that the highest density of microvessel was found in the stratum moleculare than other stratum,while the stratum pyramidale and stratum oriens were high density, mediate density respectively, and the lowest density was found in the stratum lacuno-sum.

结果表明，海马皮质各层的微血管密度，以分子层最高，以下依次为锥体细胞层和多形细胞层，而腔隙层最低。

In the stratum pyramidale of AD hippocampus, the puncta of synapsinⅠwere larger in size, surrounding both pyramidal cells and pretangles.

以上结果表明晚期AD患者海马synapsinⅠ仅表现为选择性区域性丢失。

They mainly distributed in the stratum pyramidale and stratum oriens of the subiculum and CA1 with the majority in the subiculum.After 24 weeks,the number of PV-IR neurons gradually increased.The majority of PV-IR neurons were found in the subiculum and CA1 and few in CA2.They concentrated at the border region between the stratum pyramidale and stratum oriens.

结果 PV-IR神经元最早见于23周海马结构内，主要位于下托和CA1区的锥体细胞层和多形层，以下托为主。24周开始，PV-IR神经元数量逐渐增加，大多位于下托和CA1区锥体细胞层/多形层交界处附近，少数见于CA2。

From medial to lateral, the cerebral cortex can be divided into three parts: hippocampus, general cortex and pyriform lobe, there is no distinct boundary between them, but the cell organization is different.

从内侧到外侧，大脑皮层可分为海马、新皮质和梨状皮质三部分，三者之间无明显界线，细胞排布有所区别。

Objective: To study if Lomerizine protects the hippocampus neurons cultured in vitro from the injury caused by quinolinic acid.

目的：利用洛美利嗪研究钙离子拮抗剂对兴奋性氨基酸喹啉酸所致体外培养海马神经元损伤是否有保护作用。

Methods Injecting quinolinic acid into rat hippocampus after injecting D-galactose to form the dementia rat model.

在s.c.D-半乳糖造成大鼠亚急性衰老的基础上，双侧海马内注射喹啉酸造成类AD模型。

By one trial passive avoidance response step-down tast and water maze spatial local-ization tast, we observed the effect of GASD on pathological models of the dementia rats induced byhippocampal lesions due to quinolinic acid.

采用一次性训练被动回避性跳台实验和水迷宫空间分辨能力测试实验，观察参归煎剂对喹啉酸损毁双侧海马CA1区造成大鼠记6忆障碍病理模型的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
