Abstract

Cold preservation prior to small-bowel transplantation can moderate tissue injury, although it is unable to protect the bowel graft from acute reperfusion injury. One method to reduce oxidative stress is ischemic preconditioning (IPC). The limited data regarding IPC of the bowel encouraged us to investigate the key factor in this process, i.e., the activation of nuclear factor-kappa binding (NF-kB) in bowel tissue. The intestine was preconditioned by various cycles of IPC on rats. Activation of NF-kB was detected by a chemiluminescence-based ELISA method. Our findings showed that NF-kB level was elevated significantly 30 min after IPC. One hour following IPC, NF-kB decreased to control level; 2 h after IPC, the level significantly increased again. These changes were independent of the number of IPC cycles. Our experiments with various IPC cycles revealed that even a very short IPC cycle was able to activate the IPC cascade in small-bowel tissue.
