Abstract

Background— We investigated whether electrical stimulation (STIM) of efferent vagus nerves may suppress nuclear factor (NF)-κB 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 induced by intermittent withdrawing of blood until mean arterial pressure stabilized within the range of 35 to 40 mm Hg. Application of constant voltage pulses to the caudal vagus ends (STIM; 5 V, 2 ms, 1 Hz for 12 minutes, 5 minutes after mean arterial pressure stabilization) increased survival time (VGX+Hem+Sham STIM=38±3 minutes; VGX+Hem+STIM >180 minutes), reverted the marked hypotension (VGX+Hem+Sham STIM=33±3 mm Hg; VGX+Hem+STIM=66±5 mm Hg), inhibited IκBα liver loss, and blunted the augmented NF-κB activity, decreased hepatic tumor necrosis factor (TNF)-α mRNA (VGX+Hem+Sham STIM=1.42±0.5 amount of TNF-α m-RNA; VGX+Hem+STIM=0.51±0.2 amount of TNF-α mRNA), and reduced plasma TNF-α (VGX+Hem+Sham STIM=190±24 pg/mL; VGX+Hem+STIM=87±15 pg/mL). Chlorisondamine, a nicotinic receptor antagonist, abated the effects of vagal stimulation. Conclusions— Our results show a parasympathetic inhibition of NF-κB by which the brain opposes NF-κB activation in the liver and modulates the inflammatory response during acute hypovolemic hemorrhagic shock.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Vagus nerve control of cytokine damage in hemorrhagic shock is attributable to cholinergic signals transduced intracellularly via nicotinic receptors.

    “The protective effects of vagus nerve stimulation in this model were reversed by administration of a nicotine receptor antagonist (chlorisondamine), indicating that vagus nerve control of cytokine damage is attributable to cholinergic signals transduced intracellularly via nicotinic receptors (21).”
  • Vagus nerve stimulation of rats during lethal hemorrhagic shock confers protection against hypotension, prolonged survival, and decreased TNF production.

    “Vagus nerve stimulation of rats during lethal hemorrhagic shock conferred significant protection against the development of hypotension, prolonged survival, and decreased TNF production (21).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
