Abstract

Background and Purpose— The rate of nitric oxide (NO) generation from nitrite is linearly dependent on reductions in oxygen and pH levels. Recently, nitrite-derived NO has been reported to exert a profound protection against liver and heart ischemia-reperfusion injury. In this study, we hypothesized that nitrite would be reduced to NO in the ischemic brain and exert NO-dependent neuroprotective effects. Methods— Cerebral ischemia-reperfusion injury was induced by intraluminal thread occlusion of middle cerebral artery in the adult male rats. Solutions of sodium nitrite were infused intravenously at the time of reperfusion. Sodium nitrate and carboxy-PTIO (30 minutes before ischemic surgery), a direct NO scavenger, were infused for comparisons. Results— Nitrite reduced infarction volume and enhanced local cerebral blood flow and functional recovery. The effects were observed at concentrations of 48 nmol and 480 nmol, but not at 4800 nmol nitrite and 480 nmol nitrate. The neuroprotective effects of nitrite were inhibited completely by the carboxy-PTIO. The 480 nmol nitrite attenuated dihydroethidium activity, 3-nitrotyrosine formation, and lipid peroxidation in the ischemic brain. Conclusions— Nitrite exerted profound neuroprotective effects with antioxidant properties in the ischemic brains. These results suggest that nitrite, as a biological storage reserve of NO, may be a novel therapeutic agent in the setting of acute stroke.

  • Early research indicated a therapeutic role for nitric oxide in cardioprotection in myocardial infarction models, and L-arginine treatment before reperfusion was organ-protective.

    “Early research indicated a therapeutic role for nitric oxide in cardioprotection in myocardial infarction models, 135 and L-arginine treatment before reperfusion was also organ-protective.133,136,137”

    From Nitrate-Nitrite-Nitric Oxide Pathway: Implications for Anesthesiology and Intensive Care (2010) · cites this paper as [136]

    The References section (page unavailable) lists a rat study reporting that L-arginine infusion reduced cerebral infarction volume. It does not establish that L-arginine was given before reperfusion. This paper’s Experimental Protocols instead describe administering sodium nitrite at reperfusion. (LLM, conf=0.82)

  • The protective effect of nitrite in ischaemia-reperfusion injury has been replicated by many in vivo and in vitro studies showing protection in most organs tested, including liver, brain, heart and kidneys.

    “This protective effect of nitrite in ischaemiareperfusion injury has now been replicated by many other in vivo and in vitro studies showing protection in most organs tested such as the liver [161, 162], brain [163], heart [164] and kidneys [165] and reviewed by Dezfulian C et al. [166] and Webb & Ahluwalia [167].”
  • Nitrite is a dietary constituent that protects the heart against I/R injury in many animal models during both ischemia and preconditioning stage.

    “Nitrite is a dietary constituent that protects the heart against I/R injury in many animal models during both ischemia and preconditioning stage [186,187,188,189,190,191,192].”

  • Nitrite is protective against ischemia/reperfusion and other forms of injury in multiple tissues and organs.

    “Numerous investigations have reported that nitrite is protective against I/R and other forms of injury in multiple tissues and organs (81, 125, 188), as reviewed extensively elsewhere (157).”

    From Inorganic nitrite supplementation for healthy arterial aging (2014) · cites this paper as [81]

  • The nitrite dose range encompassing protection versus loss of protection in these studies was greater than two or three orders of magnitude.

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.
