丁酸

Butyric fermentations are less useful in food preservation than those noted previously.

丁酸发酵在食品保藏中不如前面提到的那些发酵那么重要。

ABSTRACT γ-Butyrolactone autoregulator produced in Streptomyces is a low-molecular-weight compound controlling secondary metabolism and morphological differentiation in Streptomyces.

γ-丁酸内酯自动调控因子是一种由链霉菌产生的被称为微生物&激素&的小分子化合物，它控制着链霉菌次级代谢物的产生或形态分化。

Dimethyoxyphenyl Lithium and 2,4,6-trimethoxyphenyl Lithium could also react whth γ-butyrolactone to produce -hydroxypropyl 2,4-dimethoxyph

2，4-二甲氧基苯基锂和2，4，6-三甲氧基苯基锂也能与γ-丁酸内酯反应分别生成γ-羟丙基-（2，4-二甲氧基苯基）酮和γ-羟丙基-（2，4，6-三甲氧基苯基）酮。

In this work, the effects of culture factors ( MET, IBA, culture medium and culturing in dark) on root formation were studied in tissue culture of Celastrus angulatus. The results showed that the root induction was significantly affected by duration of culture in dark, while other factors were least effective.

探讨了培养因子对诱导苦皮藤试管苗生根的作用，采用正交试验设计法测试了苦皮藤生根关键因素多效唑、吲哚丁酸、暗培养及培养基中盐浓度的效应。

Using dichloropinacolone as starting material, ruthenium dioxide/celite as catalyst and sodium hypochlorite as oxidant, 3,3-dimethyl-2-oxo-butyric acid is prepared through hydrolization and oxidation two reaction steps.

以二氯频哪酮为起始原料， RuO2/Celite 为催化剂， NaOCl 作氧化剂，经水解、氧化两步反应制得3，3-二甲基-2-氧代丁酸。

In developing animals, and in certain brain areas of adult rats without cerebral injury, neurotoxic effects were noted after large-dose ketamine. These were prevented by coadministration of GABA receptor agonists.

在生长期动物以及脑部特定区域没有损伤的成年大鼠，大剂量氯胺酮才引起神经毒性，这可以被联合应用γ-氨基丁酸受体激动剂预防。

Results: NaB inhibited cell proliferation time and Concentration dependently.

结果：丁酸钠对SKM-1细胞生长的抑制呈浓度和时间依赖性。

Such dichotomous effects were noted by others for NMDA and gamma-aminobutyric acid A receptors.

这种交叉效应在 NMDA 与 r-氨基丁酸 A 受体上发现。

With the increase of excitory amino acids after cebral ischemia, the concentration of inhibitory acids such as γ-amino acid has been also increased to resist the toxicity of the excitory amino acids .

研究发现脑缺血后，伴随着兴奋性氨基酸的释放增加，脑内抑制性氨基酸如γ-氨基丁酸的浓度也升高，以拮抗兴奋性氨基酸的毒性作用。

Our results have shown that the analgesic effect of morphine administered to nucleus accumbens was blocked by intra-habenula injection of naloxone or ME antiserum, whereas the analgesic effect of morphine injected into habenula was attenuated by intra-PAG administration of naloxone or muscimol, and enhanced by bicuculline methochoride (BMC, an antagonist of GABA receptor).

本工作实验结果表明，在伏核内注射吗啡产生的镇痛作用可被缰核内注射NX或ME抗体所大部阻断，而缰核内注射吗啡产生的镇痛作用又可被PAG内注射NX或γ-氨基丁酸受体激动剂异鹅羔胺所削弱，被GABA受体阻断剂氯甲基荷包牡丹碱所增强。
