烟碱

And recovery 30 days after topping could make sure there are enough carotenoids and soluble sugar in tobacco leaf cells. Besides the contents organic acid, protein, nicotine and potassium element are controlled in a certain scope, then tobacco leaves after curing kinds of compound proportion coordination bear more fragrance precursor.

打顶后30d采收烟叶，叶片细胞内既含有较多类胡萝卜素和可溶性糖，又能将有机酸、蛋白质、烟碱和钾含量控制在一定范围内，使烟叶调制后各种化合物的比例协调。

To investigate the nongenomic effect of the glucocorticoid corticosterone on nicotinic acetylcholine receptor in PC12 cells.

目的：研究糖皮质激素皮质酮对PC12细胞烟碱受体的非基因组作用。

A Box-Behnken experimental design was applied in the design of experiments and in the analysis of the experimental data.

采用Box-Behnken法研究和探讨初始pH值、接种量和温度对菌株DN2降解烟碱的影响，获得了二次模型。

It was suggest that the yield of tobacco in unit area was significant increasing and the quality was improved along with the altitude increase in Liuyang tobacco area. The tobacco leaves production at the place where the altitude from 400 meter and 900 meter was propitious to postpone the bearing period and growth and development of tobacco plants. It was the base of maturation endurance and could advance the tobacco leave maturation degree of all parts of tobacco plant. And it could hasten the orange tobacco leave ratio of the whole tobacco plant. It was boosted leaves unwrapping of top tobacco plant and the statuses of tobacco leaves, especially the top leaves, were significantly improved. The tissue structure of all parts leaves on tobacco plant were more loosen and the colour and luster of tobacco leaves was more vivid. The nicotinamide content in top leaves were digressive at a certain extent, on the contrary, the contents of the reductive sugar and kalium were increased at different extent. At the same time, it was benefit to play down the pesticide rudimentai of tobacco leaves and increased security of tobacco leaves.

结果表明：在浏阳烟区随着海拔高度的增加，单位面积烟叶的产量有着明显的增加，烟叶质量也有一定程度的改善；在海拔400—900m的地方进行烟叶生产，有利于延长烟株大田生育期，有效缓解浏阳烟区7、8月份的高温逼熟现象，有利于烟株的生长发育，为养好烟株的耐熟性打下良好的基础、促进各部位烟叶成熟度的提高；同时可以有效的促进烟株各部位橘黄烟叶比例的上升，对上部烟叶的开片也有着明显的促进作用，烟叶身份特别是上部烟叶的身份得到明显的改善，各部位烟叶组织结构更加疏松，烟叶色泽更加鲜亮；上部烟叶烟碱含量在一定程度上有所降低，各部位烟叶还原糖、钾含量有着不同程度的增加烟叶香气特征更加明显；香气量有一定程度的增加，吸位更加醇和、余味舒适；同时也有利于减少烟叶的农药残留量，提高烟叶的安全性。

With the purified α-NT-linked affinity chromatography, nicotinic acetylcholine receptor is purified from the electric organ of ray .

以α-NT制作亲和胶柱，纯化了黑斑双鳍电鳐电器官中的烟碱型乙酰胆碱受体。

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。

A rare affection on Potassium uptake by fertilizer and topping and a high genetical stability were obtained.

蛋白质受环境条件及施肥措施、打顶措施的影响最小，烟碱受环境条件及施肥措施、打顶措施的影响最大。

Then using selective antagonists for mAChR and nAChR, inhibitor of PKC and MAPK, respectively, we probed into the molecular mechanism underlying the regulation of APP processing by HupA.

采用毒蕈碱样乙酰胆碱受体和烟碱样乙酰胆碱受体的特异性拮抗剂，以及PKC和有丝分裂原激活的蛋白激酶（mitogen-activated protein kinase， MAPK）的抑制剂，探讨石杉碱甲调节sAPPα分泌的分子机制。
