丁酸

Results Osteoblasts from human bone marrow were successfully induced and differentiated; the cuttlebones were reshaped in cuttlebone hydroxyapatite for the first time; and some tissue engineering bones, such as the osteoblasts/...

结果 人骨髓细胞培养中诱导、分化出成骨细胞；首次将乌贼骨改性为乌贼骨羟基磷灰石；构建出成骨细胞/ CHA5 0 0 R、成骨细胞/乌贼骨羟基磷灰石、成骨细胞/聚羟基丁酸酯等组织工程骨。

The increase in MAC for cyclopropane was unexpected, because published reports find only minimal actions at 122 GABAA receptors whereas isoflurane provides a large enhancement.

环丙烷对突变鼠最低肺泡有效浓度的增加出乎我们的意料，因为外界报导在α1β2γ2 γ-氨基丁酸 A 受体这一异氟烷作用最强的地方，环丙烷只有极微弱的作用。

Herein, we report the enantioselective total syntheses of slagenins A-C and their antipodes. Starting from readily available ethyl -4-chloro-3-hydroxy-butanonate, elongation of the carbon chain with diazomethane, followed by oxidation of the given α-diazoketone using distilled DMD, afforded a key intermediate α-ketoaldehyde .

本文从方便易得的-4-氯-3-羟基-丁酸乙酯出发，经重氮甲烷延伸碳连、DMD氧化相应的α-重氮酮，制得α-酮醛；该化合物与尿素在氢氟酸作用下，以协同方式非对映选择性的直接构建了cis-四氢呋喃并[2，3-d]咪唑啉-2-酮双环结构，进而合成了天然产物slagenins A、B、和C的对映体。

The resultsdemonstrate:(1) GABA causes a decrease of blood pressure and heart rate by inhibiting sympathetic nerve in the part of the diencephalon, mesencephalon and medulla.

氨基丁酸在心血管活动中起着重要的调节作用。实验结果表明：(1)GABA可以作用于部分间脑、中脑和延髓而抑制交感神经，产生降低血压，减慢心率的作用。

The morphology, component and structure of electrolytically etched surface are characterized and the mechanism of electrolytic etching and graining is also discussed based on the theoretical analysis. The components that can form barrier layer or dissolve the resisting layer on the surface of Al-Mg-Si alloy specimens are investigated through voltamperometric and chronoamperometric analysis in several solutions.

通过对Al-Mg-Si合金在各种溶液中的电流密度—电位曲线及电位—时间曲线的测量与分析，筛选出能够在Al-Mg-Si合金表面形成阻挡层的成分和对阻挡层有刻蚀作用的成分，并进行复配实验对比，优选出偏硼酸钠-硼酸、酒石酸-碳酸钠、磷酸钠-正丁酸和柠檬酸钠-柠檬酸等4种图纹电解刻蚀液体系。

This paper mainly studied on the functionalingredients in red koji such as Monacolin K , Ergosterol, GABA and so on.

完善了红曲中莫那可林K 、γ-氨基丁酸的HPLC测定方法，根据这些检测方法对红曲中的这几种功能性成分定性、定量检测。

Physical properties of the system related to the process of synthesizing ethyl 3-hydroxybutyrate were determined.

主要介绍了3-羟基丁酸乙酯合成过程中的相关物系的物性测定。

Objective To investigate the effects of intranigral injection of glutamate and gama amino butyric acid on iron metabolism in the caudate putamen nucleus of rats.

目的 探讨谷氨酸、γ-氨基丁酸对大鼠尾壳核铁代谢的影响。

The study indicated that sodium butyrate can be used to increase goblet cell number,improve the morphology of intestinal epithelium,and promote digesting and absorbing in piglets.

表明，丁酸钠能促进杯状细胞增殖，改善小肠黏膜上皮细胞的形态结构，进而促进仔猪的消化吸收，提高其生产性能，其在这些方面的作用均优于抗生素。

With semi-lignified branches of 2-year-old C. surattensis, that haleness and no diseases and pests as the materials, and treatment with clean water as CK, the effects of 250, 500, 1000 mg/L indole butyric acid and 250, 500, 1000 mg/L naphthalene acetic acid on survival rate, plant height, average rooting number and root length of shoot were studied.

方法］以生长健壮、无病虫害2年生黄花槐的半木质化枝条为材料，以清水处理为对照，研究250、500、1000 mg/L吲哚丁酸和250、500、1000 mg/L萘乙酸处理对枝条成活率、株高、平均生根数及根长的影响。
