Severe burn is known to induce a series of pathological responses resulting in increased susceptibility to systemic inflammatory response and multiple organ failure, but the underlying molecular mechanism remains unclear at present. The main aim of this study was to expand our understanding of the events leading to circulating leukocyte response after burn by subjecting the gene expression profiles to a bioinformatic analysis. ⋯ Based on an integrated bioinformatic analysis, we concluded that Lck, Jun, Cd19, Stat1, and Cdk1 may be critical 1 day after the burn. These findings expand our understanding of the molecular mechanisms of this important pathological process. Further studies are needed to support our work, focused on identifying candidate biomarkers with sufficient predictive power to act as prognostic and therapeutic biomarkers for burn injury.

This study was designed to investigate the effect of inorganic phosphate supplementation on invasive behavior of Pseudomonas aeruginosa in burn wound infections. An emulsion-based lotion containing sodium dihydrogen phosphate was formulated and then 50 female Sprague-Dawley rats with burn wounds were used to assess the effect of phosphate supplementation on swarming motility of P. aeruginosa. On the second day after burn, four groups of rats were inoculated with P. aeruginosa and one group was left as negative control. ⋯ Histopathological assessment of the tissue samples also indicated the healing process in phosphate-enriched lotion receiving group. The results showed that inorganic phosphate supplementation results in alteration of the virulence behavior of P. aeruginosa and improvement in the wound healing process. In conclusion, phosphate supplementation would be a rational strategy in the eradication of P. aeruginosa wound infection.

Despite dramatic improvements in burn care, the major part of the therapy of thermal injuries remains symptomatical in nature. A targeted approach to accelerate angiogenesis and woundhealing and reduce edema formation remains to be found. We therefore aimed to investigate the impact of anti-inflammatory, anti-coagulative and thrombolytic agents on microcirculation after thermal injuries on the mentioned parameters. ⋯ The often described positive influences of selenium for the treatment of burn patients could not be confirmed, on the contrary we found a post-traumatic expansion of the non perfused area and an increase of leukocytes in this group. The expectations to rtPA did not fulfill. Prednisolone improved angiogenesis and reduced the edema formation, both Parameters are essential for wound healing and survival of burned patients.
