Animal model of grain worker's lung.
We examined the light microscopic changes in the lungs of rabbits exposed to grain dust for variable periods of time, to determine whether an animal model of grain worker's lung could be developed. Experimental animals were exposed to grain dust at a concentration of 20 mg/m3 for 7 hr/day, 5 days/week, for up to 6 months. The lungs of these rabbits demonstrated a granulomatous interstitial pneu...
متن کاملLung function decline in laboratory animal workers.
In their recent paper Portengen and colleagues have made an important contribution to our understanding of laboratory animal allergy. However, they have omitted to draw attention to an observation of clinical importance to occupational physicians. They have suggested that the lack of decline in lung function in ‘‘experienced’’ workers may be due to the healthy worker effect. Their suggestion is...
متن کاملDecline in lung function related to exposure and selection processes among workers in the grain processing and animal feed industry.
OBJECTIVES To follow up workers in the grain processing and animal feed industry five years after an initial survey, and to monitor exposures to organic dust and endotoxin and changes in prevalence of respiratory symptoms and lung function. METHODS Outcome measures in the present survey were decline in lung function over five years, rapid annual decline in forced expiratory volume in one seco...
متن کاملEffects of gamma oryzanol on factors of oxidative stress and sepsis-induced lung injury in experimental animal model
Objective (s): There is corroborating evidence to substantiate redox imbalance and oxidative stress in sepsis that finally leads to organ damage or even death. Gamma oryzanol (GO) is one of the major bioactive components in rice bran has been considered to function as an antioxidant. The present study was carried out to evaluate the antioxidant activity of gamma oryzanol in vitro and its effica...
متن کاملRespiratory disease of workers harvesting grain.
The incidence of respiratory symptoms caused by grain dust during harvesting was surveyed in a group of Lincolnshire farmers. A quarter complained of respiratory distress after working on combine harvesters or near grain driers and elevators, with cough, wheezing, and breathlessness, sometimes so severe as to prevent work. The airborne dust around combine harvesters contained up to 200 million ...
