Genetic Effect of MBL2 Polymorphisms in Patients with Diisocyanate-induced Occupational Asthma
… Diisocyanate (DI) is the most common cause of occupational asthma (OA) in Korea. Although various mechanisms were involved in the pathogenesis of DI-OA, oxidative stress has been suggested as a potential mechanism, which leads to the formation of a complement-activating mannose-binding lectin …

Development and validation of a diagnostic tool for occupational asthma based on serial lung function measurements
… an initial investigation in the confirmation of occupational asthma. Plotting measurements in Oasys gives reproducible results and can be used by non-experts. I report a new analysis, the area between curves (ABC) score, which gives 72% sensitivity and 100% specificity using a cut off of 15 …
