Abstract

The in vivo effect of inhibitors of fatty acid amide hydrolase (FAAH) upon oedema volume and FAAH activity was evaluated in the carrageenan induced hind paw inflammation model in the mouse. Oedema was measured at two time points, 2 and 4 h, after intraplantar injection of carrageenan to anaesthetised mice. Intraperitoneal (i.p.) injections of the FAAH inhibitor URB597 (0.1, 0.3, 1 and 3 mg kg−1) 30 min prior to carrageenan administration, dose‐dependently reduced oedema formation. At the 4 h time point, the ED 50 for URB597 was ∼0.3 mg kg−1. Indomethacin (5 mg kg−1 i.p.) completely prevented the oedema response to carrageenan. The antioedema effects of indomethacin and URB597 were blocked by 3 mg kg−1 i.p. of the CB 2 receptor antagonist SR144528. The effect of URB597 was not affected by pretreatment with the peroxisome proliferator‐activated receptor γ antagonist bisphenol A diglycidyl ether (30 mg kg−1 i.p.) or the TRPV1 antagonist capsazepine (10 mg kg−1 i.p.), when oedema was assessed 4 h after carrageenan administration. The CB 1 receptor antagonists AM251 (3 mg kg−1 i.p.) and rimonabant (0.5 mg kg−1 i.p.) gave inconsistent effects upon the antioedema effect of URB597. FAAH measurements were conducted ex vivo in the paws, spinal cords and brains of the mice. The activities of FAAH in the paws and spinal cords of the inflamed vehicle‐treated mice were significantly lower than the corresponding activities in the noninflamed mice. PMSF treatment almost completely inhibited the FAAH activity in all three tissues, as did the highest dose of URB597 (3 mg kg−1) in spinal cord samples, whereas no obvious changes were seen ex vivo for the other treatments. In conclusion, the results show that in mice, treatment with indomethacin and URB597 produce SR144528‐sensitive anti‐inflammatory effects in the carrageenan model of acute inflammation.

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.
