大伞

Objective To observe the expression of nicotinic acetylcholine receptor in the brain's fimbria/fornix transected rats, the effect of ectogenic estrogen on it, and its relation with Alzhelmer's disease.

目的 以双侧穹隆海马伞切断制作阿尔茨海默病大鼠模型，观察脑内海马CA1区和皮层区烟碱型乙酰胆碱受体表达的变化，探讨与 AD相关的发病机制，并观察雌激素的干预作用。

RT-PCR/Southern blot was used to detect the change of Brn-4 mRNA expression in hippocampus after fimbria fornix transection.

取各组大鼠的海马组织，提取总RNA，采用RT-PCR/Southern 杂交方法分析穹窿海马伞切割后海马内Brn-4 mRNA的表达变化。

The bilateral fimbria-fornix of brain was transected in the fimbria/fornix transaction group.

在脑立体定位仪上，切断大鼠脑的双侧穹隆海马伞同时切除双侧卵巢，建立模拟AD的动物模型。

One group served as normal control and the others served as the 1st, 3rd, 7th, 14th, 21st and 28th day group after fimbria fornix transection, respectively.

42只SD大鼠随机分成正常对照组和切割穹窿海马伞后1、3、7、14、21及28 d组。

Fimbria/fornix transaction cutting can cause the increased of Aβ1-40 expression in many sections of the brain, which might be related to the cognitive disturbance due to Alzheimer disease.

穹隆-海马伞切断和去势的大鼠脑内多部位Aβ1-40表达增多，此可能与老年性痴呆病理改变有关。

Then hippocampi were isolated and total RNA was extracted. RT-PCR/Southern blot was used to detect the change of Brn-4 mRNA expression in hippocampus after fimbria fornix transection.

取各组大鼠的海马组织，提取总RNA，采用RT-PCR/Southern杂交方法分析穹窿海马伞切割后海马内Brn-4 mRNA的表达变化。

The expression of TrkA positive neurons is decreased in many sections of the brain in the rats with fimbria/fornix transection.Possibly it is the cause leading to the cognitive disorder and senile dementia.

穹窿海马伞切断大鼠脑内多部位酪氨酸激酶A表达减少，这种病理变化可能是认知障碍和老年性痴呆的原因之一。

Objective: To investigate the difference of Brn-4 mRNA expression between the fimbria fornix transected rats and normal ones.

I had another Belt not so broad, and fasten'd in the same Manner, which hung over my Shoulder; and at the End of it, under my left Arm, hung two Pouches, both made of Goat's-Skin too; in one of which hung my Powder, in the other my Shot: At my Back I carry'd my Basket, on my Shoulder my Gun, and over my Head a great clumsy ugly Goat-Skin Umbrella, but which, after all, was the most necessary Thing I had about me, next to my Gun: As for my Face, the Colour of it was really not so Moletta-like as one might expect from a Man not at all careful of it, and living within nine or ten Degrees of the Equinox.

另一条较窄的皮带，斜挂在我的肩膀上，也用皮条系着。这条皮带的末端，在我左胳膊下，挂着两个山羊皮袋，一个装火药，一个装子弹。我背上背着筐子，肩上扛着枪，头上撑着一顶羊皮做的大阳伞，样子又难看又笨拙。尽管如此，除了枪之外，这把伞也是我随身不可缺少的东西。至于我的脸，倒不像穆拉托人那么黑，看上去像一个住在赤道九度、十度之内的热带地区那种不修边幅的人。

The biggest turtle said to the smallest one,' Gohome and get the umbrella.

于是最大的那只乌龟对最小的乌龟说，"回家去取伞吧。"

Do you know, i need you to come back

你知道吗，我需要你回来
