title: Effects of free fatty acids and L-carnitine on the spontaneous motility of rat isolated uterine horn.
abstract: In the present investigation the effects of free fatty acids (FFA) and L-carnitine were investigated on the rat isolated uterine horn. The cumulative addition of FFA and L-carnitine to the isolated organ bath produced a significant increase of isometric developed tension and functional activity, especially evident at 5 mM carnitine concentration. No variations in the frequency of contractions were found. These data suggest a possible role of FFA as energy source in the rat uterus.
