Laboratory studyOther animals

Design
Laboratory study
Subjects
Wild-type mice and Clock mutant mice (a model of nocturia); numbers not stated in the abstract
Dose used in the study
Palmitoylethanolamide, 9-HODE or 4-HDoHE administered to wild-type mice; dose and route not stated in the abstract
Duration
Serum sampled every 8 hours
What was measured
Circadian serum levels of PEA, 9-HODE and 4-HDoHE; voiding frequency and bladder capacity in metabolic cages after giving each lipid.

What the authors reported

This laboratory study found:

  • Serum PEA and 9-HODE followed a daily rhythm in normal mice and were higher and lost their rhythm in Clock mutant mice.
  • Giving PEA or 4-HDoHE increased voiding frequency, and PEA decreased bladder capacity.
  • The authors say these changes resemble those in elderly people with nocturia.

Limits of this study

A mouse study; it cannot show effect in people. It reports that palmitoylethanolamide increased voiding and reduced bladder capacity, an unwanted effect in this model. Dose is not in the abstract. The authors declare no competing interests.
