title: Content of prostaglandins E and F in the blood plasma and kidneys in arterial hypertension (clinical-experimental study).
abstract: A dynamic study is made of the content of PGE and PGF2 alpha in the kidneys of rats with experimental coarctation hypertension, as well as the PGF2 alpha-metabolite in the blood plasma of the same experimental model in rats and in patients with arterial hypertension. The level of the PGF2 alpha-metabolite tends to decrease both in the animals with experimental hypertension and in hypertonic patients. In rats with 30-day hypertension low values are established in 55 per cent, while in 45 per cent there are high values of the PGE level in the kidney homogenate compared with the control group. The concentration of PGF2 alpha in the left ("endocrine") kidney (whose artery originates distally from the place of aortic coarctation) is higher than the concentration of the same PG in the right kidney. Our findings give grounds for the following assumptions: 1. The PGF2 alpha-metabolite as hormone and partly PGE in the kidneys seem to be involved in the pathogenesis of arterial hypertension as compensatory factors. 2. PGF2 alpha in the kidneys probably participates directly as one of the elements of the complex pathogenesis of arterial hypertension.
