[Modification of lipoxygenase products in bone by the linoleic acid content of the diet].

Eicosanoids are supposed to participate in the regulation of bone metabolism. 30 male white rats of the wistar strain were fed on a diet rich in linoleic acid (LA), on a diet poor in LA and on a pellet diet after 3 month up to an age of 5 month. The formation of leukotrienes (LT) C4, D4, and E4 from the proximal tibia metaphysis after LA rich diet has been compared to the formation from LA poor and pellet diet. LA rich diet increased the formation of LTC4, D4 and E4 in the proximal tibia metaphysis. The properties of eicosanoids as local mediators in the bone were discussed.
