[The treatment of severe arterial hypertension in patients with chronic kidney failure with captopril and beta-adrenoblockaders].

Twenty nine patients with chronic renal failure associated with severe essential hypertension, 10 of whom being on programmed hemodialysis, were treated with captopril, a converting enzyme inhibitor (n = 21) and sectral-400, a cardioselective beta-blocker (n = 11). Blood pressure (BP) changes and renin-angiotensin-aldosterone system parameters were studied by radioimmunoassay. When given in a daily dose of 25 to 100 mg for a long time, captopril provided a good and satisfactory antihypertensive effect in 9 patients; a weak or no effect was achieved in 9 and 5 patients, respectively.

[Plasmapheresis in preoperative care of patients with thyrotoxicosis].

The authors studied the efficacy of plasmapheresis in preoperative management of patients with thyrotoxicosis in intolerance of and resistance to thyrostatic agents. Seventy-three patients were examined. Preoperative management was accomplished by gravitation plasmapheresis (PP) with a PP-0.

[Method of quantitative determination of inorganic iodine in the body].

An original method of quantitation of body inorganic iodine, based upon a simultaneous administration of a known dose of stable and radioactive iodine with subsequent radiometry of the thyroid, was proposed. The calculation is based upon the principle of the dilution of radioactive iodine in human inorganic iodine space. The method permits quantitation of the amount of inorganic iodine with regard to individual features of inorganic space.

[Radioimmunodiagnosis in the correction of plasmapheresis methodology in thyrotoxicosis].

Differences in the rated and actual results were revealed during postoperative plasmapheresis in patients with thyrotoxicosis who did not tolerate or were resistant to thyrostatics. It was assumed that it was caused by a rise of the level of thyroid hormones resulting from heparin premedication. Gravitation plasmapheresis following heparin administration (150-200 U per 1 kg of body mass) was used in a study group of 25 patients.
