In which 18.02 and 230.08 are the molecular weights of water and sodium tartrate dihydrate, respectively; W is the weight, in mg, of sodium tartrate dihydrate; and V is the volume, in mL, of the Reagent consumed in the second titration.

其中18.02和230.08是水和酒石酸钠的各自分子量，W是二水酒石酸钠的重量，以mg计，V是第二次滴定消耗的卡尔试剂的体积，以毫升计。不好意思，废话不多说，请大家多指教

The protocol of this research would be carried out as follows: to evulate effects of sodium ferulate on experimental colitis model of rats induced by acetic acid and investigate its mechanism; to evulate effects of sodium ferulate on experimental colitis model of rats induced by trinitrobenzene sulfonic acid with ethanol and investigate its mechanism.

我们在建立乙酸、三硝基苯磺酸(2，4，6-trinitrobenzene sulfonic acid，TNBS)两种经典大鼠结肠炎模型的基础上，采用灌肠给药方式来观察阿魏酸钠对这两种大鼠实验性结肠炎的作用效果，进而从不同角度对其有关机制进行探讨，以期为阿魏酸钠成为IBD有效治疗药物的开发应用提供实验依据。

The results of this reseach showed that administration of SF intracolonically had protective effect on the colon injury in the rat model of colitis induced by acetic acid enema, which was probably due to the mechanism of antioxidation, inhibition ofarachidonic acid metabolis and platelets activation, administration of SF intracolonically also showed protective effect on the colon injury in the rat model of colitis induced by trinitrobenzene sulfonic acid and ethanol, which was probably due to antioxidation and inhibition of macrophages activation.

实验研究表明，大鼠分别经乙酸、TNBS和乙醇处理后均出现典型的结肠炎症状，给药后分别评价结肠粘膜损伤指标、结肠组织病理变化，检测结肠组织炎症指标、结肠组织氧化损伤指标及主要炎性细胞因子改变；实验结果：阿魏酸钠对大鼠乙酸性结肠炎结肠粘膜损伤具有缓解保护作用，其机制可能与直接抑制炎症结肠粘膜花生四烯酸代谢过度，抑制血小板活化，清除大量氧自由基有关；阿魏酸钠对大鼠TNBS性结肠炎粘膜免疫损伤亦具有缓解保护作用，其机制可能与抗氧化，抑制结肠巨噬细胞活化有关。

Now our main products include; calcium propionate, sodium propionate, sodiumacetate, animal and vegetable hydrolyzed protein.

目前我所生产的产品有：丙酸钙、丙酸钠、乙酸钠、动植物水解蛋白、酵母抽提物，蛋白专用活性炭等。

In this paper, the antiseptic effect of the complex form of both Calcium Propionate and Sodium Dehydroacetate and the complex form of Calcium Propionate ,Sodium Dehydroacetate and Potassium Sorbate in bread have been studied .

研究了丙酸钙与脱氢醋酸钠两者复配形式、丙酸钙与脱氢醋酸钠和山梨酸钾三者复配形式对面包的防腐效果。

With increase of concentrations of sodium propionate or sodium pyruvate, the abundance of PEPCK-C mRNA in the hepatocytes increased significantly first, whereafter decreased.

在原代单层培养的新生犊牛肝细胞培养液中分别加入不同浓度丙酸钠、丙酮酸钠、胰岛素、胰高血糖素和瘦蛋白，培养12h后，应用半定量RT-PCR方法检测体外培养的肝细胞PEPCK-C mRNA的丰度。

On the successful basis of bovine hepatic cell culture and competitive DNA template of pyruvate carboxylase gene,effects of propionate sodium and pyruvate sodium on mRNA of PC gene in cultured bovine hepatocyte in vitro was determinated quantitively by competitive RT-PCR.

在成功构建牛肝细胞培养模型和PC基因DNA竞争模板的基础上，采用竞争RT-PCR方法检测了丙酸钠和丙酮酸钠对体外培养新生牛单层肝细胞PC基因mRNA丰度的影响。

Propionate sodium ; pyruvate sodium ; pyruvate carboxylase gene ; mRNA level ; competitive RT-PCR ; bovine hepatocyte

丙酸钠；丙酮酸钠；丙酮酸羟化酶基因； mRNA水平；竞争RT-PCR ；牛肝细胞

Key words: propionate sodium; pyruvate sodium; pyruvate carboxylase gene; mRNA level; competitive RT-PCR; bovine hepatocyte

丙酸钠；丙酮酸钠；丙酮酸羟化酶基因；mRNA水平；竞争RT-PCR；牛肝细胞

Sodium propionate and sodium pyruvate could promote liver gluconeogenesis by up-regulating the abundance of PEPCK-C mRNA in the hepatocytes, but the up-regulation was limited.

表明，丙酸钠、丙酮酸钠能通过上调体外培养的新生犊牛肝细胞PEPCK-C mRNA的表达而促进肝糖异生代谢，但上调作用是有限的；胰岛素能通过下调体外培养的新生犊牛肝细胞PEPCK-C mRNA的表达而抑制肝糖异生代谢，且下调作用呈剂量依赖性；胰高血糖素与胰岛素作用刚好相反；瘦蛋白未起直接的调节作用。
