淋巴细胞

BACKGROUND AND AIM: Associations between genetic polymorphisms of CYP1A1 MspⅠor GSTT1 among residents from an electronic waste recycling site in China, and the frequencies of micronucleated binucleated cells in peripheral blood lymphocytes were investigated.

背景与目的：探讨代谢酶CYP1A1 Msp Ⅰ位点和GSTT1基因多态性与电子垃圾处理区居民外周血双核淋巴细胞微核率的关系。

Methods Lymphocytes with different MTHFR C677T genotypes from the donors were cultured for 9 days in media with different concentrations of folic acid and the frequencies of micronucleated binucleated cell was evaluated by cytokinesisblock micronucleus cytome assay.

采用9天淋巴细胞长期培养辅以胞质阻断微核细胞组分析，分析不同浓度的叶酸对三种MTHFR C677T基因型乳腺癌人群和健康人群双核细胞微核率的影响与差异。

Levels of lead, cadmium and copper in blood and urine were determined by atomic absorption spectroscopy, and frequencies of micronucleated binucleated cells in peripheral blood lymphocyte were measured by cytokinesis-blocked micronucleus assay.

Results The positive rate of binucleated granulocytes was 0%in normal contrast group. It was 53.0%in acute myeloid leukemia, 46.2%in chronic myeloid leukemia, 41.7%in reactive granulocytosis, and 38.4%in myelodysplastic syndrome. they were significantly higher than 8.2%in common anemia, 12.5%in idiopathic thrombocytopenic purpura, and 0%in lymphocytic leukemia.

结果 双核粒细胞阳性率，27例正常对照组为0，急性髓细胞白血病53.0%(80/151)、慢性髓细胞白血病46.2%(18/39)、反应性粒细胞增多症41.7%(20/48)、骨髓增生异常综合征38.4%(33/86)，明显高于一般贫血8.2%(8/98)、特发性血小板减少症12.5%(4/32)和急性淋巴细胞白血病为0。

Objective: To study the influence of Boswellia carteriiBirdw extractive of different concentrations on human Jurkat cell apoptosis at different time points.

目的 ：检测不同浓度、不同时间作用下乳香提取物对人急性T淋巴细胞白血病细胞株Jurkat细胞的促凋亡作用。

We found that the SCE frequency of somatic cells in Bufo bufo gargarizans was 7.83±0.49,which was higher than that of mammals in general.

此外，我们还测定了中华大蟾蜍淋巴细胞的SCE频率，发现其SCE频率比哺乳动物高，为7.83±0.49。
