title: Usefulness of procalcitonin in Pseudomonas burn wound sepsis model.
abstract: Procalcitonin (PCT), a precursor of calcitonin, and endotoxin were determined in the burn wound sepsis model in which 21 Sprague-Dawley rats were scalded approximately 30% on their back. On day 2 post burn, the wounds were inoculated 1 x 10(8) colony-forming units of Pseudomonas aeruginosa. On day 5 post burn P. aeruginosa was detected by blood culture in 10 of the 21 rats (47.6%). The mortality rate 7 days after burn was 90.5%. Significant correlations were observed between serum endotoxin levels and serum PCT levels on day 5 post burn (r = 0.860, p<0.001). It was suggested that endotoxin may induce the release of PCT and that measuring the levels of PCT may be useful in diagnosing burn wound sepsis.
