The deceptive aortic root.

abstract：BACKGROUND:We investigated whether electrical stimulation (STIM) of efferent vagus nerves may suppress nuclear factor (NF)-kappaB activation and the inflammatory cascade in hemorrhagic (Hem) shock. METHODS AND RESULTS:Rats were subjected to bilateral cervical vagotomy (VGX) or sham surgical procedures. Hem shock was i...
