Open Access Abstract Introduction The use of moderate hypothermia during experimental cardiac surgery is associated with decreased expression of tumour necrosis factor TNF -a in myocardium and with myocardial protection. In order to identify the cellular mechanisms that lead to that repression we investigated the effect of hypothermia during cardiac surgery on both main signalling pathways involved in systemic inflammation namely the nuclear factor-KB NF-kB and activating protein-1 pathways. Method Twelve female pigs were randomly subjected to standardized cardiopulmonary bypass with moderate hypothermia or normothermia temperature 28 C and 37 C respectively six pigs in each group . .
