The vascular perfusion was recorded 14% and 57% higher in 60 °C and 80 °C treated animals respectively when compared to control animals. However, at 100 °C due to highest vessel damage the perfusion was reduced to 53% compared to control. CONCLUSION Present study demonstrates that the device is able to generate precise and uniform burn wound in mice model. The device may be useful for burn related studies and validation of burn wound care products. BACKGROUND The direct-instillation nasal allergen challenge (NAC) and the environmental exposure chamber (EEC) are two methods of conducting controlled allergen provocations. The clinical and biological comparability of these methods has not been thoroughly investigated. OBJECTIVE To compare clinical and immunologic responses to cat allergen in NAC versus EEC. METHODS Twenty-four participants were randomized to receive either NAC followed by a two-day challenge in an EEC or a two-day challenge in EEC followed by NAC. Challenges were separated by 28-day washout periods. We measured total nasal symptom scores (TNSS), peak nasal inspiratory flow (PNIF), nasal (0-8hours) and serum cytokines, serum antibodies, peripheral blood antigen-specific T-lymphocytes, and gene expression in nasal scrapings. The primary outcome was the TNSS area under the curve for the first 3 hours after allergen exposure in NAC or after initiation of exposure in EEC. RESULTS Both challenges increased IL-5 and IL-13 in nasal fluids and serum and resulted in altered nasal cell expression of gene modules related to mucosal biology and transcriptional regulation. Changes in gene modules, more so than cytokine measurements, showed significant associations with TNSS and PNIF. Overall, EEC exposure generated larger responses and more early terminations compared to NAC. Although the two challenges did not correlate in symptom magnitude
