海马

The density of dendritic spines—tiny, thornlike projections that provide more surface area for the reception of nerve signals—increased in this region as the female's levels of estrogen rose.

由美国洛克斐勒大学的伍列及麦克尤恩所完成的一些精采研究，显示雌鼠在动情周期中，海马的 CA1区会出现消长变化：当雌鼠体内雌性素含量上升时，该区神经元树突棘的密度也随之增加；树突棘是树突上头的微小针状突起，可增加接收神经讯息的表面积。

Neural toxity in vivo can be induced exactly by co-injection of coacervated-type A B MO and IBA in the hippocampus , which could be partlymodeled behavior and pathological characterization of AD.

凝聚态Aβ_(1-40)与IBA联合大鼠海马注射具有明确的在体神经毒性作用，可以较好的模拟AD行为和病理表现。

Rats in the treatment group were injected with 10 μL of human insulin of rapid gene synthesis （1 ×10%5 U/L）immediately after unclamped the bulldog clamp and reperfusion, while rats in the sham-operation group and control group were injected with normal saline at the same volume.

分别于全脑缺血再灌注1，3，5d，假手术组（1只／时相点）、缺血对照组（6只／时相点）、胰岛素治疗组（6只／时相点）大鼠断头取脑，行免疫组化染色，光镜下观察海马CA1区神经元酪氨酸羟化酶和多巴胺-β-羟化酶表达的变化。

So the neural pathways that underly the septo-hippocampal CA1 LTP remains to be revealed.

故隔-海马CA1区LTP现象的神经通路基础有待揭示。

Results IL-6R immunoreactive cells were observed in the anterior of optical area,the ventromedial nucleus,the periventricular nucleus and arcurate nucleus of the hypothalamus.The strongly stained cells are concentrated in the granule cell layer of the dentdate gyrus and the pyramidal cells of the CA1-CA2 fields of the hippocampus.IL-6R positive cells are also detected in the cortex, the ventromedial nucleus of the thalamus,bed nu stria,olfaltory tubercle.

结果 IL-6R 免疫反应性细胞主要分布在下丘脑的视前区、腹内侧核、室旁核和弓状核；在海马， IL-6R 阳性细胞呈强阳性，密集分布于齿状回颗粒细胞层和 CA1～ CA2锥体细胞层；在大脑皮层、嗅结节、丘脑腹内侧核、终纹床核等处也有 IL-6R 阳性细胞。

Results as follows;(1) At 25th week of fetal age, the staining intensity and cell density almost equalled to that at birth in cervical spinal cord, brainstem, hippocampus, and vermis of cerebellum; while there are only 1/4 cell densities in cerebral cortex.

用胶质原纤维酸性蛋白抗体进行免疫组织化学染色。结果表明：(1)在颈段脊髓、脑干、海马和小脑蚓部于胚胎25周其GFAP染色强度、细胞密度接近出生时水平。

ACET inhibit the descending of Bax,prolong its descending period andthen promote its expression,in order to weaken the inhibition of the apoptosis during 4 to 10 days after seizure and then promote the apoptosis during 10 to 14 days after.

埋线治疗通过抑制Bax蛋白表达的下降、延长其降至低峰值的时程，致使在癫痫发作后的中期(4d～10d)抑制大鼠海马神经元凋亡的作用减弱；继而通过促进Bax蛋白表达的回升，致使在癫痫发作后的远期(10d～14d)出现促进凋亡的作用。

The model of dementia was established by pretreatment with aluminium chlorid, PO.

目的 观察VE对AD大鼠海马β-APP表达的影响。方法使用三氯化铝诱导建立AD模型大鼠。

CB、CR、PV immunohistochemistry were used to analyze the changes of the interneuron numbers.

用免疫组化检测不同时间点海马不同区域CB、CR、PV蛋白质的表达。

BACKGROUND: We studied the effects of isoflurane on hippocampalsynaptic transmission and paired-pulse plasticity, under invivo intact interneuron circuitry.

背景：作者在体研究具有完整的中间神经电路中异氟醚对海马突触传递和双脉冲可塑性的影响。

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。
