Abstract

Objective Ischemia-reperfusion injury is a pathologic event characterized by tissue damage. It is mediated by tumor necrosis factor (TNF) and other cytokines that activate complement and proteases and stimulate fibrinolysis, degranulation of white blood cells, and free radical production. We recently reported that vagus nerve stimulation (VNS) suppresses endotoxin-induced cytokine synthesis through alpha bungarotoxin-sensitive cholinergic receptors. VNS protects against endotoxin-induced shock by inhibiting hepatic and cardiac synthesis of TNF. Here, the effects of VNS on suppression of ischemia-reperfusion injury and cytokine release were studied in a rat model of aortic occlusion.Methods Adult male Lewis rats were subjected to laparotomy and suprarenal aortic clamping for 15 minutes followed by reperfusion. Blood pressure, heart rate, and respiratory rate were recorded every 3 minutes for 90 minutes. Exposed cervical vagus nerves in the experimental group were stimulated for 5 minutes before and after aortic occlusion, with constant voltage (1 V, 2 ms, 5 Hz); sham-operated animals received no stimulation. TNF levels in serum and organs were measured with enzyme-linked immunosorbent assay ELISA (BioSource International, Camarillo, Calif). Data analysis was performed with the Student t test.Results Control animals had shock develop (mean, 59% decrease in blood pressure) whereas blood pressure in the stimulated animals did not decrease (control versus stimulated animals, P <.05). VNS significantly inhibited TNF levels in serum (7 +/- 1 ng/mL versus 45 +/- 6 ng/mL; P =.0008), heart (21 +/- 11 ng/g protein versus 85 +/- 15 ng/g protein; P =.01), and liver (16 +/- 2 ng/g protein versus 42 +/- 12 ng/g protein; P =.02).Conclusion VNS significantly attenuates TNF synthesis and shock during reperfusion injury in a standard model of aortic occlusion. Clinical evaluation of VNS for this condition may be warranted.

Claims other papers make about this one

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

  • Intracerebral administration of CNI-1493 increases vagus nerve activity and confers protection against ischemia/reperfusion-mediated damage.

    “Intracerebral administration of CNI-1493, a tetravalent guanylhydrazone that stimulates muscarinic brain networks, increased vagus nerve activity and conferred significant protection against ischemia/ reperfusion-mediated damage (17,44).”
  • Vagus nerve stimulation significantly attenuates cytokine responses in a rat model of aortic ischemia/reperfusion injury.

    “Vagus nerve stimulation significantly attenuated cytokine responses in a rat model of aortic ischemia/reperfusion injury (44).”
  • The protective effects of intracerebral CNI-1493 require vagus nerve signals.

    “The protective effects of intracerebral CNI-1493 required vagus nerve signals because vagotomy ablated the protective effects of administering the drug.”
  • Reperfusion of ischemic tissues stimulates cytokine overproduction, including TNF, IL-1, and HMGB1, which contributes to the pathogenesis of resulting tissue damage.

    “Reperfusion of ischemic tissues stimulates cytokine overproduction (e.g., TNF, IL-1, HMGB1), which contributes to the pathogenesis of resulting tissue damage (42)(43)(44).”

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.
