[Change in the prostaglandin and catecholamine levels in spontaneously hypertensive rats fed diets with different polyunsaturated fatty acid contents].

The authors provide the data on the content of prostaglandins and catecholamines in biological fluids (blood and urine) derived in experiments on 28 rats aged 4 months with spontaneous hereditary hypertension given the diets with varying content of polyunsaturated fatty acids during pre- and postnatal periods. Rats fed the diet containing sunflower and linseed oil manifested a significant decrease in arterial blood pressure and activation of prostaglandin and sympathoadrenal systems.
