The interactions of n-6 and n-3 fatty acids on prostaglandin metabolism in the isolated rat mesenteric vessels were studied. Sprague-Dawley rats (200-220 g) were fed for two weeks a fat-free semi-synthetic diet supplemented with 10% by weight of different combinations of Evening Primrose Oil (Efamol), a rich source of linoleic acid (LA) and gamma-linolenic acid (GLA), the immediate precursor of dihomo-gamma-linolenic acid (DGLA), and Polepa (POL), a marine oil rich in eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. The combinations of supplement were as follows: 9% Efamol - 1% POL, 8% Efamol - 2% POL, 7% Efamol - 3% POL, 6% Efamol - 4% POL, 5% Efamol - 5% POL. The outflow of thromboxane (TxB2), prostacyclin (6-keto-PGF1 alpha), PGE2, and PGE1 was decreased in relation to the proportion of marine oil in the diet, except for the group which received 8% Efamol - 2% POL, and which showed an increase in 6-keto-PGF1 alpha, PGE2, and PGE1. The decrease in TxB2 was much greater than those of 6-keto-PGF1 alpha or PGE2, while PGE1 followed the same pattern as prostacyclin and PGE2. These results suggest that n-3 fatty acids, at high concentrations, inhibits conversion of both DGLA and AA to eicosanoids. Low concentrations of fish oil may, in contrast, increase formation of desirable 1 and 2 series eicosanoids.
