Effect of Cannabinoid Receptor Agonists on Streptozotocin-Induced Hyperalgesia in Diabetic Neuropathy

Bujalska, Magdalena·2008·Pharmacology

Abstract

The effect of CB-1 and CB-2 receptor agonists, as well as an influence of a non-selective inhibitor of nitric oxide synthase (NOS), L-NOArg, and an inhibitor acting preferentially on cyclooxygenase-1 (COX-1), indomethacin, on the action of cannabinoid receptor agonists in a streptozotocin (STZ)-induced neuropathic model was investigated. When administered alone, a non-selective cannabinoid receptor agonist, WIN 55,212-2, a potentially selective CB-1 cannabinoid receptor agonist, Met-F-AEA, and a selective CB-2 cannabinoid receptor agonist, AM1241, dose-dependently reduced STZ-induced hyperalgesia. The results of the present study also demonstrated that inhibitors of COX and NOS increase antihyperalgesic activity of low doses of CB-1 and CB-2 receptor agonists. Hypothetical consequences of this phenomenon are discussed.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Either single or repeated administration of WIN55,212-2 or AM1241 dose-dependently attenuated STZ-induced hyperalgesia.

    “In particular, either single or repeated administration of WIN55,212-2 or AM1241, dosedependently attenuated STZ-induced hyperalgesia (Bujalska, 2008).”
  • THC and WIN55,212-2 produce antinociception in rodent STZ-induced peripheral neuropathy.

    “Several studies have demonstrated that THC (Williams et al, 2008) and WIN55,212-2 (Bujalska, 2008;Doğrul et al, 2004;Ikeda et al, 2013;Jahanabadi et al, 2016;Mohammadi-Farani et al, 2010;Ulugol et al, 2004;Vera et al, 2012;Vincenzi et al, 2013) produce antinociception in rodent STZinduced peripheral neuropathy.”
  • Daily pretreatment with indomethacin or L-NOArg increased the anti-hyperalgesic actions of low doses of WIN55,212-2, AM1241, and MET-F-AEA in streptozotocin rats to a greater extent than the cannabinoid alone.

    “Daily pre-treatment with indomethacin (COX-1 inhibitor) or L-NOArg (non-selective NOS inhibitor) increased the anti-hyperalgesic actions of low doses of WIN55,212-2, AM1241 and MET-F-AEA in STZ rats to a greater extent than the cannabinoid administered alone, suggesting the presence of antinociceptive synergism between cannabinoid and COX pathways.107”
  • There is antinociceptive synergism between cannabinoid and COX pathways in streptozotocin rats.

    “suggesting the presence of antinociceptive synergism between cannabinoid and COX pathways.107”

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.
