  • Title: [The role of prostaglandins in the renal regulation of blood pressure (author's transl)].
    Author: Ducobu J, Vanherweghem JL, D'Hollander A, Guerisse P.
    Journal: Nouv Presse Med; 1979 Oct 08; 8(38):3041-6. PubMed ID: 534168.
    Abstract:
    In response to ischaemic or vasoconstrictor stimuli the kidney reacts by synthesising prostaglandins (PG) which modify local vascular tone. They induce a compensatory vasodilatation and direct the blood flow towards the internal cortex. It is thus not necessary to attribute a systemic role to PG in order to understand their haemodynamic action. This explains the natriuresis following the injection of PG both in the animal and in man. Nevertheless the direct effet of PG upon the tubular reabsorption of sodium remains controversial since very different experimental models lead to contradictory conclusions. Despite these disparate data, it is probable that PG are intimately involved in the pathogenesis of hypertension. A lack of PG or a deficiency in their metabolism may be responsible in essential hypertension.
