Suppression of monosodium urate crystal-induced inflammation by black currant seed oil.
The subcutaneous air pouch formed in Sprague-Dawley rats was used to study the effect of diets enriched in black currant seed oil (BCSO) on acute inflammation induced by monosodium urate crystals. The BCSO enriched diet suppressed significantly both the cellular and fluid phases of inflammation (polymorphonuclear leucocyte and exudate accumulation). In contrast, administration of normal chow or of a diet enriched in safflower oil (polyunsaturated fatty acid control) did not influence monosodium urate crystal-induced inflammation in this model. The findings indicate that a diet which provides both n-6 (gammalinolenic acid) and n-3 (alpha-linolenic acid) fatty acids as substrates alternative to arachidonatic acid for oxidative metabolism, modifies monosodium urate crystal-induced acute inflammation.
