Based on the different permeability of DNA-intercalant dyes YO-PRO-1 and propidium iodide to the membrane of viable, apoptotic and necrotic cells, cell samples were stained with 4μmol/L YP and 4μg/ml PI for 10 min, and the fluorescence intensity of both YP and PI were measured by fluorometer at Ex/Em wavelength of 485/538nm and 530/590nm, respectively.

根据正常细胞、凋亡细胞和坏死细胞的细胞膜对核酸荧光染料的不同选择通透性，用4μmol/LYO-PRO-1和4μg/ml碘化丙啶(Propidiumiodide，PI)染色96孔板中的细胞样品。分别在485/538和530/590的检测波长下借助荧光分光光度计检测细胞样品孔的YP和PI荧光强度。

A warning signal from the system which indicates high EC or EC ratio of a dairy cow is used to inform the milker to pay attention to the suspected cow. The detection thresholds of EC and ECR to determine whether a quarter or a dairy cow is infected with mastitis correspond with the criterion of SCC = 500×103 cells/ml for quarter foremilk of a dairy cow. The performance of online system for mastitis detection in dairy cows is evaluated with several methods, such as the detection thresholds, running analysis and discrimination analysis.

以分房乳 SCC 500 × 103 cells/ml 作为乳房炎感染与否的门槛值，由牛旁采样分房乳样的检测与分析，探讨影响牛乳 EC 大小的相关因素及其关系，如分房乳中的氯离子浓度、挤乳时间、挤乳前后及乳成份，利用变异数分析探究未感染与感染乳房炎的分房乳之间，其 EC 及 ECR 物理性质，SCC、乳酸去氢酵素及 pH 化学性质及乳脂率、蛋白质及乳糖等乳成份的差异，进而利用统计鉴别分析探讨 EC 相关参数结合乳成份参数对乳房炎检测的准确度。

Both of them showed no toxic effect on mice at the testing dose of 10 mg/kg. The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test showed that both of the formicary extracts were potent radical scavengers and their scavenging activities were dose-dependent. Furthermore, at higher concentrations (5～10 mg/ml) both of them exhibited significantly higher DPPH scavenging activity than butylated hydroxytoluene.

二苯基三硝基肼(1，1-diphenyl-2-picrylhydrazyl ，DPPH)自由基的清除能力的检测表明：两种蚂蚁窝甲醇提取物都具有显著的自由基清除能力，并呈现出剂量依赖性，而且，在高浓度时(5～10 mg·mL-1)，它们的自由基清除能力甚至显著地高于二丁基羟基甲苯(butylated hydroxyl toluene，BHT)。

Surface attractant-2.6 g dissoled in 8 ml water.

表面诱食剂2.6g溶解在 8 ml 水里。

The maximum allowable concentration of germanium in rice was 0.060 μg/ml.

锗在水稻体内的最高允许浓度为0.060μg/ml。

Methods Supernatant (1.5 ml) of different doses of the traditional Chinese medicine was collected by normal saline immersion and 2.5×104 Toxoplasma gondi i tachyzoites were added in each paste well for 8 hours.

用生理盐水浸泡不同剂量的常青胶囊，各取上清液1.5 ml，加入2.5×104弓形虫速殖子，作用8h后，将速殖子腹腔接种及灌胃接种正常小鼠，观察发病情况。

Results : No pus and pathological inflammation were observed on mice vagina mucus treated with 1 mg/ml PI-IgG 3 hours before gonococcus challenge.

而低于浓度1mg／ml及长于3h兔抗PI-IgG处理的小鼠阴道组织病理可检及炎症细胞，但其它检查结果阴性。
