Methods Pancreatic cancer cell panc-1 was treated with oxamate for 48 h,the mitochondrial membrane potential was measured by flow cytometry(Rodamin-123),and the activity of intracellular lactate dehydrogenase was studied by enzymohistochemistry.

方法体外培养人胰腺癌细胞panc-1，分别加入不同浓度的草氨酸盐培养48 h后，行酶组织化学染色及罗丹明123染色，观察细胞糖酵解关键酶乳酸脱氢酶活性及线粒体膜电位。

Results: Comparing with movement fatigue group, blood glucose contents were significantly increased but oxypropionic acid and urea nitrogen contents were significantly increased; testosterone and T/C were significantly advanced, myocardium SOD activity was significantly increased, while MDA was significantly decreased in cluytyl alcohol preparation group.

结果：和运动疲劳组相比，补充二十八烷醇制剂组大鼠血糖显著升高，血乳酸、血尿素氮显著降低；T、T/C比值显著增高，心肌SOD活性显著增强，MDA含量显著降低，且效果优于丙酮酸－肌酸组。

Methods: Movement fatigue group serve as model, and one time exhaustion movement was given in each group, examined their blood glucose, oxypropionic acid, urea nitrogen, testosterone, corticosterone contents and myocardium superoxide dismutase activity and malonaldehyde contents and ocmputed T/C.

以运动性疲劳大鼠为模型，测定大鼠血糖、血乳酸、血尿素氮、血睾酮、皮质酮水平、心肌SOD活性、MDA含量及计算T/C比值。

Reversal of paraparesis by idebenone was paralleled by normalization of 31P-MRS, serum lactate and central motor conduction.

通过使用艾地苯醌的投入后而获致的轻瘫与31P -MRS、血清乳酸盐和中央运动传导等的正常化相应地、平行地出现。

For example, it is a pathogenic bacterium and has endotoxins; it secretes protein into the periplasm and often into inclusion bodies. Bacillus subtilis is an attractive host for the production of heterologous secretory proteins. Many genes has succeed expressed in Bacillus subtilis, and the plasmid vectors for Bacillus subtilis are now taken from other genus bacterium, such as Staphylococcus aureus or lactococcus lactis and so on. As it is clear to known that these plasmids are far from optimal for Bacillus subtilis, because of low efficiencies of cloning and high levels of replicating instability.

枯草芽胞杆菌是目前原核表达系统中分泌表达外源蛋白较理想的宿主，近几年已在枯草芽胞杆菌中成功表达了多种基因，但大多都应用来源于金黄色葡萄球菌、乳酸杆菌等的载体来表达外源基因，由于其在枯草芽胞杆菌中存在分离复制的不稳定及外源基因的克隆表达效率低的现象，故都不是枯草芽胞杆菌的最佳选择，还有待改进。

It's a perfect substitute of petrolic products and extensivly applied for injection, squeeze film, blown, fabric industry and area.

聚乳酸是一种生物降解环保材料（在堆肥的条件下，分解成二氧化碳和水），其不仅不受石油危机的影响，还可以解决白色污染问题，是石油基产品的良好替代品；广泛的应用在注塑、吹膜、挤片、纤维等行业和领域，如用来生产电子产品、玩具、文具、食品包装和其它一次性的用品等。

Results The phenotypical features of galactococcus MG 1363, IL 1403 and Lactobacillus ATCC 4356 accorded with that in the Bergey's manual of determinative bacteriology.

结果 乳酸乳球菌乳脂亚种MG 1363、IL 1403及嗜酸乳杆菌ATCC 4356其表型特征分别与伯杰氏手册中相应细菌特征一致。

Interestingly we found that high concentration of L-phenylalanine (Phe, 10mM) and DL-β-phenyllactic acid (PL, 10mM) decreased 〓, while phenylacetic acid (PAA, 10mM) could decreased 〓, then increased, finally decreased 〓. With the normal extracellular balance solution replaced by calcium-free and natrium-free balance solution, PL did not change its effect on intracellular free calcium.

我们用钙成像技术检测氨基酸及其衍生物对未成熟神经元胞浆游离钙浓度的影响，结果发现高浓度苯丙氨酸降低胞浆游离钙，苯乙酸使胞浆内钙浓度降低后升高最后又降低，苯乳酸使胞浆内钙降低更明显。

Cells in the bron choalveolar lavage fluid were counted and differentiated, as well as the amounts of total protein, albumin and the activities of alkaline phos phatase, lactate dehydrogenase and type Ⅳ collagenase (matrix metallco proteinases, MMP-2, MMP-9) were detected.

计数支气管肺泡灌洗液中的细胞数并行分类，测定总蛋白、白蛋白含量及碱性磷酸酶、乳酸脱氢酶及Ⅳ型胶原酶(MMP-2、MMP-9)活性。

And the transformation efficiency of Enterococcus faecalis is obviously higher than that of Lactobacillus plantarium by pulse electroporation with different voltages, which suggests that the two strains of LAB have different usage in the research of genetic engineering of LAB.

经过16SRNA全长序列分析及配合生理生化实验鉴定，结果显示球菌为肠球菌属中的粪肠球菌，杆菌为乳酸杆菌属中的植物乳杆菌，是两株胃肠道内正常定植菌。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
