Moreover, the dust cells were found in the granulomas and the visceral pleural lymphatic vessels in the pleura and the hilar pulmonary lymph nodes in sarcoidosis and silicosis. 在结节病和矽肺病的肉芽肿内、胸膜和肺门淋巴结等处的淋巴管内均可见尘细胞;
The high pH values produced by dust was unfavorable for the cells survival and the dusts with a low bio-resistance were safe for cells. 粉尘所形成的高pH值不利于细胞的生存,低生物持久性的粉尘对人体是安全的。
The ultrastructural changes, for example, vacuolization in mitochondria and degranulation in endoplasmic reticulum in dust cells of the lungs were observed. 在肺尘细胞中看到了超微结构变化,如线粒体空泡化和内质网脱粒。
The results showed that positive reaction to ConA occurred in the cells treated with nickel refining dust or MNNG in a dose dependent manner, whereas reaction in the cells treated with TiO 2 was negative. 结果表明,用镍冶炼烟尘和MNNG处理的细胞均与ConA发生了凝集,呈剂量-依赖关系。用TiO2处理的细胞凝集反应为阴性。
Apoptosis and bcl-2 expression of dust cells in human bronchopulmonary lymph nodes and macrophages treated with carbon particles were observed with TUNEL staining and bcl-2 antibody labeling. 用TUNEL染色法和bcl2抗体标记法观察淋巴结内尘细胞和碳粒处理后的巨噬细胞的凋亡变化和bcl2表达。

Objective To investigate apoptosis and bcl-2 expression of dust cells in human bronchopulmonary lymph nodes and murine peritoneal macrophages treated with carbon particles and study the relation of apoptosis of dust-laden macrophages and structural changes of the lymph nodes. 目的研究人支气管肺淋巴结尘细胞和大鼠腹膜腔巨噬细胞吞噬碳粒后的凋亡和bcl2表达,探讨巨噬细胞凋亡与淋巴结结构变化之间的关系。
The ultrastructure and chemical component of the dust granules in the pulmonary phagocytes ( dust cells) of group A ( 3 cases) and group B ( 3 cases) were observed and analyzed by transmission electron microscope ( TEM) and analytic electron microscope ( AEM). 透射电镜(TEM)及分析型电镜(AEM)观察测定吞噬细胞内尘粒的超微结构及其元素成分。
The morphological metrology analyzing showed that there was a close correlation between dust exposure and the increase in percentage of dust cells, and surface area of dust cells, too. 对每一巨噬细胞内尘含量的形态计量分析表明,随着染尘剂量的增加,含尘巨噬细胞总数的百分率随之上升,巨噬细胞的表面积也随之增加,呈剂量-效应关系。
Methods Distribution of dust particles, apoptotic cells and structural changes of the lymph nodes were viewed on paraffin sections and ultrathin sections. 方法取人支气管肺淋巴结,作石蜡切片和超薄切片,观察尘粒分布、凋亡尘细胞和组织结构变化。
The silica dust, effector cells and cytokines would interact with each other, forming as a complex, and then activate multiple celluar signaling pathway to regulate the pulmonary fibrosis. 当石英粉尘进入肺内,尘粒、效应细胞、细胞因子等之间彼此相互影响,构成复杂的细胞分子网络,从而激活多种信号传导途径,多方面调控肺纤维化进程。
Comet assay were applied to evaluate the DNA damage induced by cement dust in human epithelial oropharyngeal cells. 采用彗星实验检测水泥尘对口咽部上皮细胞DNA的损伤程度。
