title: [Placental fatty acids in the guinea pig during pregnancy].
abstract: Prostaglandins are involved in different stages of reproduction. In respect to the placental metabolism of prostaglandins in the Guinea pig, we have studied the composition of Guinea pig placenta in free and total fatty acids. The arachidonic and dihomo-gamma-linolenic acids, precursors of prostaglandins of series 2 and 1, and the linoleic acid were quantified at different gestational ages using a gas-chromatography capillary column technique. Only the linoleic acid shows a significant increase at the end of gestation.
