Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 The same doctors who don't believe a word of what WE tell them we are suffering from, due to mold exposure, have decided to believe their lab rats.  Great! Probably, after another 20 or 30 years of cutting up dead rats, they will announce that THEY have discovered that mold also causes a TOXIC reaction.

Copyright Journal compilation © 2009 Asian Pacific Society of Respirology KEYWORDS airway remodelling • Aspergillus fumigatus • asthma • bronchial hyperresponsiveness • inflammation ABSTRACT Background and objective:  Epidemiological evidence indicates a close link between exposure to fungi and deterioration of asthma. However, the role of fungi as an exogenous precipitant for initiation and progression of asthma has been incompletely explored. In this study, the effects of Aspergillus fumigatus exposure on airway inflammation and remodelling in a rat model of chronic asthma were investigated. Methods:  The rat model of chronic asthma was established by systemic sensitization and repeated challenge with ovalbumin (OVA). The asthmatic rats were exposed to chronic intranasal inhalation of A. fumigatus spores. Changes in airway inflammation, remodelling and BHR were measured after exposure to the fungus. Results:  Chronic inhalation of A. fumigatus spores elevated the production of T helper 2 (Th2) cytokines, increased the concentration of total serum IgE, and resulted in the recruitment of eosinophils and lymphocyte infiltration into the airways of asthmatic rats. Goblet cell hyperplasia, mucus hyperproduction and subepithelial collagen deposition were also induced by inhalation of the fungus. The remodelling changes induced by inhalation of the fungus paralleled the changes in BHR in this rat model of asthma. Conclusions:  Chronic exposure to A. fumigatus aggravated Th2 airway inflammation, promoted airway remodelling and increased BHR in OVA-sensitized and -challenged rats.  http://www3.interscience.wiley.com/journal/121682088/abstract   Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 LOL Joe, You got that right. What a load of rat poison... Â Sickbuilding Syndrome should be one of your greatest concerns.www.biotoxin.info The same doctors who don't believe a word of what WE tell them we are suffering from, due to mold exposure, have decided to believe their lab rats.
