| Research Abstract |
Hyperthermia is considered an important condition that may contribute to multiple organ failure(MOF) associated with endothelial cell damage. We demonstrated that endothelial cells may exhibit a temperature-dependent mechanism of cytokine interleukin(IL)-8releases and the suppression of cytokine protein production after transient hyperthermia stimuli even though an increased level of IL-8mRNA was observed. As there is a long-term effect of IL-6or8modulation after transient hyperthermia with increasing in mRNA expression after incubating endothelial cells under high-temperature stimuli, then the process might subsequently lead to neutrophil infiltration into the injured tissue, which in turn could worsen the outcome by enhancing secondary injury processes.
