Hypothesis
The study investigates the effect of L-carnitine and its congeners on the release of arachidonic acid metabolites from rat peritoneal cells.
Conclusion
Carnitine treatment modified the macrophage component of an inflammatory site, but did not significantly influence TNF formation.
Supporting Evidence
- Carnitine treatment significantly reduced the number of nucleated cells isolated from peritonea.
- All treatments stimulated the basal release of prostaglandin E2, 6-keto-prostaglandin F1α, and leukotriene B4.
- The A23187 stimulated release of 6-keto-PGF1α and LTB4 was increased by all three compounds.
Takeaway
This study looked at how carnitine affects certain substances released by immune cells in rats, finding that it can change some of these substances but not others.
Methodology
Male Wistar rats were fed carnitine or its congeners, and their peritoneal cells were analyzed for eicosanoid release after stimulation.
Limitations
The treatment regime may not have been appropriate to influence the release of mediators of inflammation.
