Laboratory studyOther animals

Design
Laboratory study
Subjects
C57BL/6J and FAAH knockout mice; numbers not stated in the abstract
Dose used in the study
No palmitoylethanolamide was given; a single intravenous bolus of anandamide 20 mg/kg
Duration
Not stated in the abstract
What was measured
An extraction and HPLC-MS/MS method for anandamide, 2-AG, their oxidised metabolites, oleoylethanolamide and palmitoylethanolamide in kidney, and formation of DiHETE-EAs in vivo.

What the authors reported

The authors synthesised reference DiHETE-EA metabolites using mouse liver cytosol and present a solid phase extraction and HPLC-MS/MS method that quantifies anandamide, 2-AG, their metabolites, oleoylethanolamide and palmitoylethanolamide, and detects DiHETE-EAs formed in kidney after anandamide injection.

Limits of this study

An analytical methods paper in mice; palmitoylethanolamide was one measured analyte and no PEA was given. It cannot show effect in people. The authors declare no conflict of interest.
