The results show that the change in the oscillating period was linearly proportional to the concentration of Benzylpenicillin Sodium over the range from 2.47mg/L- 0.0123mg/L. Using the procedure, the content of the antibiotic in a bought production is determined and the result was consistent with that by HLPC.

Results The patients in ACI group had a 38.07± 32.14 ku/L ox-LDL antibody level and in TIA group had a 25.18±9.17 ku/L ox-LDL antibody level. A significant difference as compared with the patients in the two group (P.05). The other biochemics index had no dependability in the two groups.

结果 急性脑梗死组血清氧化型低密度脂蛋白抗体为38.07±32.14 ku/L，短暂脑缺血组为25.18±9.17 ku/L，二组比较有显著性差异(P.05)；而与其它生物化学学指标无相关性。

RESULTS: The growth speed, weight, developmental uniformity, bionergy and fecuncity of the Bombyx silkworm descent dramatically as they eat the feed that the concentration of 2,4-DCP over 0.8 mmol L~-1 or NP exceed 0.500 mmol L~-1. But the effect on reproductive capacity vary with gender difference, it's more obvious on the late-stage of development and periods of metamorphosis such as ecolysis, pupation, edosion. There may be cumulative effect inside the Bombyx siliworm.

结果 家蚕幼虫食下含0.8 mmol·L~(-1)以上浓度的2，4-DCP或0.500 mmol·L~(-1)以上浓度的NP饲料，生长速度、生长量、发育整齐度、生命力和生殖能力都明显下降；生殖能力所受影响应性别而不同；家蚕发育后期和蜕皮、化蛹、羽化等变态时期影响更加明显，在蚕体内可能有累积作用。

Briefly, coronal brain sections (100 mm)were cut with a vibratome, postfixed with 4% glutaraldehydein 0.1 mmol/L cacodylate buffer (pH 7.4) for 1 h, andthen with 1% osmium tetroxide in 0.1 mmol/L cacodylatebuffer for 2 h. After rinsing with distilled water, the brainsections were treated with 1% aqueous uranyl acetateovernight, dehydrated in an ascending series of ethanolsto 100%, followed by dry acetone, and then embedded inDurcupan ACM. Ultrathin sections (0.1 mm) were cut andstained with 3% lead citrate and subsequently examinedwith a Zeiss transmission electron microscope (Zeiss Inc.,Thornwood, NY, USA).

简单的说，先用切刀制成100um的冠状脑切片，然后用含有4%戊二醛在0.1 mmol/L的二甲砷酸缓冲液(PH7.4)中固定1小时后，放在含有1%四氧化锇的0.1 mmol/L的二甲砷酸缓冲液中2小时，接着用蒸馏水冲洗后，放在1%的aqueous uranyl acetate中过夜，接下来用梯度酒精(至100%)脱水，然后用丙酮干燥，再用Durcupan ACM包埋，切成0.1um的超薄切片后用3%的lead citrate染色，随后用透射电子显微镜观察。

Lipase mediates esterification between caproic acid (0.6mol/L) and ethanol (0.6mol/L) in n-heptane at 40℃. The decrease in caproic acid is measured by titration and 1 unit of lipase synthetic activity is defined as 1 μmol caproic acid consumed per min.

在40℃下，脂肪酶催化己酸(0.6mol/L)与乙醇(0.6mol/L)在正庚烷中进行酯合成反应，通过滴定法测定剩余的己酸，1个脂肪酶有机相合成酶活单位定义为：在测定条件下每分钟消耗1μmol己酸的酶量。

Cotton and silk fabrics were dyed with natural carminic acid after the Iron ion pre-mordant treatment. The K/S values of the fabrics were characterized. The single factor process experiments were carried out for mordant concentration, temperature and time. The optimal process parameters were mordant concentration cotton: 1×10^(-3mol/L and 10 min at 90℃; silk: 1×10^(-3)mol/L and 10 min at 40℃.

将铁离子前媒染处理后的棉、丝织物采用天然染料胭脂虫酸进行染色，以染色织物的K/S值进行表征，对媒染剂浓度、温度、时间3个因素进行了单因素工艺实验，得到了铁离子前媒染棉、丝织物的最佳工艺参数（棉：1×10^(-3)mol/L， 90℃，10分钟；丝：1×10^(-3)mol/L， 40℃，10分钟）。

Methods: CD34(superscript +) cells from fetal liver were isolated with a magnetic cell sorting kit and were cultured. Cells pretreated with or without protein kinase C inhibitor chelerythrine chloride (3 μmol/L) were induced by 5 ×10^(-7)mol/L tretinoin for 24 h, and then incubated in serum-free medium. Expressions of genes in treated cells were assayed by Western blotting and RT-PCR.
