It has been reported that exogenously administering MT could prolong life, postpone aging, and reduce the incidences of age-related diseases.

MT对机体有着广泛的影响，如对神经内分泌-免疫系统和应激反应的调节，抑制肾上腺、性腺、甲状腺分泌，抗炎、镇痛、镇静、催眠等作用。

Methods The virus titer in culture fluid was measured by enzyme-linked immunosorbent assay.The HTNV-antigen in MsC was detected by indirected immunofluoresence assay and enzyme immunoassay.The shape and ultrastructure of infected MsC were observed by light microscope and transmission electron microscopy respectively.

采用免疫标记技术和电镜技术观察HTNV-A9株对人胚肾小球系膜细胞的感染情况和病毒唑、磷甲酸钠对病毒感染的抑制作用。

Objective:To study on the effects of cooking oil fume on immune function and genetics of occupationally exposed staffs.

烹调油烟可抑制职业接触人群的体液免疫功能，并具有一定的遗传毒

Results:(1) The 90Y activity was higher while the contumination of 90Sr was less than 0.0031%;(2) The efficiency of 90Y-labeled antibodies was over 90%,the activity of labeled antibody maintained 82.3%;(3) Tumor size of all 90Y-antibody-treated model was significantly less than that of all 90Y-Cl3-treated model, the average survival time of the mice of the 90Y-antibody-treated group was significantly longer than that of the 90Y-Cl3-treated group;(4) In the tissue sections extensive necrosis was observed in all 90Y-antibody-treated tumor, the living tumor cells were immunohistochemically stainable with PcNA.

结果：(1)EDTA淋洗法制备90Y纯度高，其相对含量可达99.997％；(2)单克隆抗体的90Y标记率达90％以上，抗体蛋白活性保持82.3％；(3)治疗结果表明治疗组肿瘤明显小于对照组，原肿瘤的指数生长规律遭到破坏，治疗组生存期明显长于对照组；(4)组织学切片显示治疗组肿瘤有广泛坏死，PcNA免疫组化显示治疗组肿瘤细胞增殖受到明显抑制。

METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide or caspase-3 inhibitor (DEVD-CHO, 100 μmol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and IκΒ-α were detected by Western blotting methods.

用二甲基亚砜对照、100μmol/L caspase-3抑制剂预处理乳腺癌Bcap37细胞3h后，加入不同浓度的长春碱，以MTT法检测肿瘤细胞增殖能力，以细胞DNA片段分析及PI染色法检测肿瘤细胞凋亡，以蛋白免疫印迹法检测pro-caspase-3和IκΒ-α蛋白的变化。

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