[Effect of diet therapy on metabolism of prostaglandins in patients with hypertension and obesity].

Significant disturbances of immune regulation of prostaglandine metabolism were found in patients with hypertension and obesity. Use of antisclerotic diet with low sodium contents promoted positive changes of clinical symptoms of diseases, in particular normalizations of process of immune regulation of prostaglandine metabolism connected with formation of natural antibodies.

[Effect of atherosclerotic diet containing polyunsaturated omega-3 fatty acids on level of natural antibodies to prostaglandin F2alpha in patients with ischemic heart disease, hyperlipidemia and hypertension].

The hypolipidemic, antiatherogenic and thrombolytic effects and decrease of prostaglandin F2 alpha (PG) excretion were observed in 55 patients suffering from Ischemic heart disease, hyperlipidemia and hypertension fed the antiatherosclerotic diet containing 20 g of eiconol during 55 days. The low initial level of natural antibodies to PGF2 alpha was increased significantly in blood serum. Authors consider that decrease of PGF2 alpha level under diet influence is connected not only with the change of fatty acid composition of cell membranes but also with increasing of natural antibody production.

[Plasma mineralocorticoids--aldosterone and desoxycorticosterone-- in patients with"low-renin"arterial hypertension].

The plasma aldosterone (A) and desoxycorticosterone (DOCS) levels were measured in 10 patients with primary aldosteronism and in 2 subgroups with low-renin hypertensive disease (LRHD): (1) those with normal adrenal glands++ (n - 11) and (2) those with structural changes in the cortex (n - 11). The patients from Subgroup 1 showed the lowest basal A and DOCS levels (107.29 +/- 12.

[Urinary prostaglandin levels in patients with arterial hypertension with benign and malignant course].

With radioimmunoassay, daily urinary levels of prostaglandins E2 and F2 alpha (PGE2, FGF2 alpha were measured in 45 patients with hypertensive disease, 13 patients with chronic diffuse glomerulonephritis and 14 healthy persons. A progressive reduction in urinary PGE2 excretion was found to accompany the occurrence of labile arterial hypertension (AH), its stabilization, and development of malignant AH in patients with hypertensive disease or chronic diffuse glomerulonephritis. When labile AH developed, urinary PGF2 alpha excretion was increased, but when AH stabilized, its excretion became increased up to the baseline level.

[Renal prostaglandins and hypertension].

A total of 154 patients with essential hypertension (EH), 24 patients with renovascular hypertension (RVH), and 130 Wistar rats were investigated. PGE2 and PGF2 alpha levels were assayed radioimmunologically in renal venous blood and urine of the patients, and the synthesis of PGE2 and PGF2 alpha in renal tissue, renal PGE-9-ketoreductase activity and urinary PG excretion were measured in rats. It was demonstrated that the PGE2 synthesis was depressed in the vascular channel and the renal uropoietic system, with elevated F/E rations, in patients with arterial hypertension.
