| Outline of Final Research Achievements |
Electrical stimulation of the vagus nerve (VNS) is known to prevent acute lung injury(ALI)/multiple organ dysfunction (MODS)in animal models of acute injury such as trauma/hemorrhagic shock (T/HS). We have previously shown that lipid mediators (such as lyso-phsophatidylcholine and arachidomic acid) release into mesenteric lymph (ML) following T/HS and induce ALI/MODS. The aim of our study was to investigate the role of VNS on lipid mediators in the post-T/HS ML, however, we couldn't find any significant chages in lipid mediators in post-hemorgahic shock ML after VNS (5V, 5Hz, 10 min). Therefore, we develop the new electrical stimulators to find ideal stimulation condition which attenuate the production of lipid mediators in the mesentewric lymph. Fyrther study is needed to investgate the role of VNS on lipid mediators in ML.
