Development of immunoassays for biomonitoring of hexamethylene diisocyanate exposure.
Hexamethylene diisocyanate (HDI) is used widely to manufacture polyurethanes for paints and coatings. It is an irritant and a chemical asthmagen. The U.S. Occupational Safety and Health Administration time-weighted average permissible exposure limit is 5 ppb and the ceiling limit is 20 ppb. We sought to develop a sensitive and specific immuno-bioassay to supplement workplace air monitoring and ...
متن کاملEffects of hexamethylene diisocyanate exposure on human airway epithelial cells: in vitro cellular and molecular studies.
In this study we developed an in vitro exposure model to investigate the effects of hexamethylene diisocyanate (HDI) on human airway epithelial cells at the cellular and molecular level. We used immunofluorescence analysis (IFA) to visualize the binding and uptake of HDI by airway epithelial cell lines (A549 and NCI-NCI-H292) and microarray technology to identify HDI sensitive genes. By IFA, we...
متن کاملå¡ CASE REPORT å¡ Hypersensitivity Pneumonitis Induced by Hexamethylene Diisocyanate
A case of hypersensitivity pneumonitis (HP) induced by hexamethylene diisocyanate (HDI) is described. Serial determinations of the lymphocyte surface phenotypes by two-color assay revealed the following: 1) increased activated cytotoxic T lymphocytes in the bronchoalveolar lavage fluid (BALF), and 2) increased percentage and absolute number of non-major histo compatibility complex (MHC)-restric...
متن کاملEffect of 1,6-hexamethylene diisocyanate exposure on peak flowmetry in automobile paint shop workers in Iran.
The aim of this study was to investigate the effects of occupational exposure to 1,6-hexamethylene diisocyanate (HDI) on peak flowmetry in automobile body paint shop workers in Iran. We studied a population of 43 car painters exposed to HDI at their workplaces. Peak expiratory flow was tested for one working week, from the start to the end of each shift. Air was sampled and HDI analysed in para...
متن کاملCharacterization and comparative analysis of 2,4-toluene diisocyanate and 1,6-hexamethylene diisocyanate haptenated human serum albumin and hemoglobin.
Diisocyanates (dNCOs) are low molecular weight chemical sensitizers that react with autologous proteins to produce neoantigens. dNCO-haptenated proteins have been used as immunogens for generation of dNCO-specific antibodies and as antigens to screen for dNCO-specific antibodies in exposed individuals. Detection of dNCO-specific antibodies in exposed individuals for diagnosis of dNCO asthma has...
