objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera（p＜0.05）.there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。结果在实验组中，与血清浓度为0的浓度组相比，与各浓度组血清共同培养的小鼠骨髓cfu-e和bfu-e的集落数均明显减少，且随血清浓度的增加，小鼠骨髓cfu-e和bfu-e的集落数逐渐减少，各浓度组间差异有显著性（p＜0.05）。结论尿毒症患者血清抑制小鼠骨髓红系祖细胞集落形成，随患者血清浓度的增加，抑制作用增强，具有剂量依赖性。

Results Human complement can be activated by unsensitized EL-4 cell through the first pathway.

Moreover, in many countries with unclean water supplies and poor sanitation, mothers were using unsterilized water to mix infant formula or not cleaning the bottles properly - with devastating results for children.

此外，在很多国家，由于饮水不洁与卫生条件差，母亲们用未经消毒的水来稀释婴儿配方奶粉，或是没能将奶瓶洗干净，对孩子来说就会带来灾难性的后果。

objective in order to exploit the natural resources of chinese herbs,the inhibitive effects of the compositions of28chinese herbs on the growth of8common bacteria in oral cavity were determined.methods sen-sitive test of these bacteria were carried out by mtt method.at the same time,chessboard dilution method was used for combined sensitive test.results the compositions of28chinese herbs can inhibit the growth of5bacteria in dif-ferent levels,but the effects on other3bacteria are not obvious.quercetin and usnic acid have better effects on5bacteria than other26herbs compositions,with mic0.03125～0.125mg/ml and0.0156～0.0625mg/ml.conclu-sion quercetin and usnic acid can inhibit the5bacteria growth more effectively than other26herbs compositions.

目的 测试28种中药有效成分抑制8种口腔常见致病菌的作用，为抗菌中药有效成分用于口腔感染性疾病的防治做一些探讨。方法选择28种有抗菌作用的中药的有效成分，采用噻唑蓝法对8种口腔常见致病菌作药物敏感实验，同时采用液体棋盘稀释法进行联合药敏实验。结果 28种中药有效成分对3种牙周细菌抑制作用不明显，对另5种口腔常见细菌有一定的抑制作用，其中松萝酸和槲皮素有较强的抑菌作用，mic值分别在0.0156～0.0625mg/ml和0.3125～0.125mg/ml之间。结论所选28种中药成份中，松萝酸和槲皮素具有较强的抑菌作用。

Results showed that extraction abilities depends on the hydrophobic of solutes which pK〓 values are similar, e. g. acetic, propionic, butyric and valeric acids, while pK〓 values affect dominantly the extraction abilities of acids with similar hydrophobic, e. g. formic, acetic, chloroacetic, dichloroacetic, and trichloroacetic acids. Meanwhile, diluents and TOA concentration also affect the extraction equilibria of acids through the specific basicity of TOA .

TOA对酸性差别很小的一元羧酸如乙酸、丙酸、丁酸、戊酸的萃取能力主要取决于羧酸的疏水性参数logP；TOA对疏水性参数差别较小的羧酸如甲酸、乙酸、一氯乙酸、二氯乙酸、三氯乙酸的萃取能力主要取决于羧酸的电性参数；稀释剂的种类、TOA的浓度都会影响TOA的表观碱度pH〓，并通过TOA的表观碱度影响羧酸的萃取平衡。

Pattern of Candida species isolated from patients with diabetes mellitus and vulvovaginal candidiasis and their response to single dose oral fluconazole therapy ［J］.

同时MFC测定获得的结果也表明，利用更高浓度抗真菌剂稀释的标准液体培养基，极少能观察到完全抑制真菌的生长，但分子量为25和745ku的PEI对MY7238分离物的抑制则是例外。

After dilution of the preparation of two pesticides can be difficult to dissolve some of the wettable powder or a small amount of pesticides, be more fully dissolved, the more evenly distributed so that more accurate measurement, not only to enhance the effect of medication, but also reduce the phytotoxicity of occurred, but also access to the original drug to reduce the risk of poisoning.

农药经过两次稀释配制，能够使某些不易溶解的可湿性粉剂或用量微小的农药，得到更充分的溶解，分布的更均匀，使计量更加准确，既提高用药效果，又减轻药害的发生，还能减少接触原药中毒的危险。
