Objective To investigate the effect of different concentrations of sodium arsenite on the reactive oxygen species and lipid peroxidate of the lymphocytes of rats cultured in vitro and the antagonism of sodium selenite and vitamin C.

目的 观察不同浓度的亚砷酸钠(NaAsO2)对体外培养的大鼠淋巴活性氧群和细胞内脂质过氧化物含量的影响，并探讨亚硒酸钠(NaSeO3)和维生素C对砷毒性的拮抗作用。

Methods The selected microorganisms were cultivated at 37℃ in culture media with different concentration of sodium arsenite and counted by microscope, and arsenic content in bacteria was detected by ASA.

采用在培养基中加入不同浓度亚砷酸钠的方法研究各菌株对砷的耐受性，并在显微镜下进行细菌量计数，采用超低温捕获原子吸收分光光度仪测定菌体中砷含量。

He activity of y-GT also had dose- dependent and time-dependent effect and became lowest on day 7 at the concentration of 0.5 and 1.0 umol/L. The activity of TAT increased. On day 4, the cells treated with 0.25, 0.5 and 1.0 umol/L of As2O3 had higher activity compared with control group (P.05) and it continued afterwhile.

AT随着各给药组时间的延长而上升，并随给药剂量增大而上升程度更大，培养第4天，0.25 μmol／L浓度的亚砷酸组TAT的比活性较对照组高(P＜0.05)，0.5 μmol／L、1 μmol／L浓度的亚砷酸组TAT的比活性较对照组更高(P＜0.01)，以后各天给药组均高于对照组(P＜0.01)。

Methods 0, 2.5, 5, 10, 15 and 20 μmol/L arsenious acid-treated human hepatocellular carcinoma HepG2 cells were cultured under hypoxia for 8 hours. The cell proliferation and cell viability was assayed by WST-8 and the trypan blue dye exclusion method. The expressions of HIF-1α in human hepatocellular carcinoma HepG2 cells were checked by RT-PCR and Western Blot.

以0、0.25、0.5、1、2和4μmol/L的亚砷酸处理人肝癌细胞HepG2缺氧环境中培养8h；1μmol/L的亚砷酸处理人肝癌细胞HepG2缺氧培养0~10h，WST-8法和台盼蓝染色法分析细胞增殖和活力，采用RT-PCR和Western Blot方法检测肝癌细胞中HIF-1α的表达。

Liver vein pours into the embolism to unite the arsenous acid treatment primary liver cancer is one extremely is worth the application the method of treatment.......

肝动脉灌注栓塞联合亚砷酸治疗原发性肝癌是一非常值得应用的治疗方法。亚砷酸；原发性肝癌；治疗

Sodium arsenite group and sodium arsenate group were made by 300 mg/L per day of sodium arsenite and sodium arsenate respectively. The mice were sacrificed after 10 months for liver function and pathologic examination. The expression of MMp-8, TIMP-2, Col-Ⅰ、Col-Ⅲ mRNA were detected with real time flourescence quantitative PCR. The result was controlled with 18s.

亚砷酸钠组和砷酸钠组给予普通饲料和砷溶液。10个月后处死小鼠，血清进行肝功能检测；苏木素－伊红染色部分肝组织；Trizol-酚－氯仿一步法提取小鼠肝组织总RNA，紫外分光光度法测定总RNA浓度及纯度，实时荧光定量PCR法测肝组织中MMP-8、MMP-2、Col-Ⅰ、Col-Ⅲ mRNA的表达，以18S基因作为质控。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
