Heme oxygenase-1 participates in the resolution of seawater drowning-induced acute respiratory distress syndrome.

The aim of the present study was to investigate whether heme oxygenase-1(HO-1) participated in the resolution of seawater drowning-induced acute respiratory distress syndrome (ARDS). In this study, gross and microscopic morphology of pulmonary tissue, computed tomography images and biochemical indexes were continuously observed from 15min to 15day after seawater drowning. The content and activity of HO-1 were determined by western-blot and spectrophotometric method, respectively.
