[Radiocirculography in patients with cerebrovascular disorders].

The cerebral blood flow time (CBFT) was examined in 100 patients with brain circulatory disorders with the aid of radiocirculography (RCG). Use was made of 99mCc-pertechnetate (37 MBq) and a two-channel "Gamma" radiograph manufactured in the Hungarian Republic. The rate of film movement amounts to 160 mm/min at the time constant 10.

[Isotope nephrography in patients with obesity].

131I-hippuran nephrography conducted in 80 patients aged 26-53 with I and II degree obesity has revealed changes in the excretory phase (36.9 per cent of the patients with I degree obesity) and secretory and excretory and some vascular and metabolic abnormalities were registered in 79.4 per cent of those with II degree obesity.

[Radionuclide diagnosis of kidney calculi].

Radionuclide investigations were conducted in 322 patients with nephrolithiasis. Unilateral calculosis was established in 46.3% of the patients, bilateral calculosis in 50.

[Scintigraphy of the myocardium in postinfarct cardiac fibrosis].

The authors conducted a scintigraphic study of 50 patients with a 2-7 year history of myocardial infarction and clinical findings of postinfarction myocardiofibrosis. 201Tl-chloride with the activity of 74 MBq and the Picker 500 magna-scanner (USA) were employed. Four projections were used in the study.

[Radionuclide diagnosis of postinfarction aneurysms using 113m InCl3].

The authors conducted a scintigraphic study of the cardiac cavity in 140 patients to detect postinfarction aneurysms. 113m In Cl3 (185 MBq) and the conventional Picker I magna-scanner (USA) were employed. A conclusion has been made as to a good choice of the angiotropic marker 113m In for the diagnosis of postinfarction aneurysm of the left ventricle and the determination of a degree of its thrombosis.

[Complex radioisotope diagnosis of thyroid gland diseases in vivo and in vitro].

A variety of in vivo and in vitro methods: radioactive iodine accumulation, thyroid suppression and stimulation test, a scintigraphic study and a radioimmunoassay to determine triiodothyronine-binding capacity (free T3), thyroxine (T4) concentration and the effective thyroxine ratio (ETR), was used for diagnostic specification and accurate planning of therapy of patients with thyroid diseases. The suppression test combined with the results of the in vitro analysis (free T3, T4 and ETR) was decisive for establishing diagnosis.

[Carcinoembryonic antigen, its clinical and prognostic significance in malignant tumors of the gastrointestinal system].

A radioimmunoassay to determine the CEA level in 100 patients with GIT malignant tumors was performed. The test was shown to be of particular value for making a preoperative prognosis of the disease. In operated on patients it could be used for early diagnosis of recurrences and metastases.

[Clinical and prognostic significance of determining the carcinoembryonic antigen in patients with gastrointestinal cancer].

The paper discusses the results of a radioimmunologic assay of carcinoembryonic antigen (CEA) levels in 100 cases of gastrointestinal cancer. CEA--PRIST kits (Phadebas, Sweden) and NGR-603 automatic gamma-unit (Tesla, Czechoslovakia) were employed. The test proved to be highly instrumental in the preoperative evaluation of prognosis and early detection of recurrence and metastasis.

[Plasma levels and the antihypertensive effect of the preparation celiprolol].

The antihypertensive activity of the new cardioselective adrenergic blocker celiprolol in hypertonic disease, stage I-II, according to WHO as compared with the preparation acebutolol was assessed under the conditions of double blind study. Thirty patients with arterial hypertension were included in the study if after one week placebo period, met the criteria for inclusion. Blood samples from each patient, were collected for the determination of plasma concentrations of celiprolol before the beginning, by 2, 15 and 29 day of the treatment, 24 hour after the last intake and before the following intake.
