Role of DAPK gene promoter methylation on the development of lung cancer in F344 rats exposed to Yunnan tin mineral dust;

Study on the Interaction between Malignant Transformation of Human Pulmonary Epithelial Cells and Activation of Fibroblasts Induced by Yunnan Tin Mine Dust and the Mechanisms;

To monitor dust in coal mines for evaluation on dust hazards and assay its elements in order to provide science evident for exploring the dust occupational injury mechanism, coal mine dust were sampled by dust sampler for measuring the admissible level under short-term contact (PC-STEL) and the time-weighted average admissible concentration (PC-TWA).

The changes in amounts of bacterium and consumed glucose (GLU) and 14 kinds of main cations after the action of mineral dusts with escherichia coli and staphylococcus epidermidis were determined.

Surface properties, free radicals released by mineral dusts or stimulated phagocyte play important roles in causing ce.
