The influence of iodinized oil on the function of hypophysis-thyroid system and the contens of middle molecule peptides in healthy people depending on iodine supply of the body

Abstract: The influence of iodinized oil (IO) on the function of hypophysis-thyroid system and the content of middle molecule peptides (MMP) in the blood serum in people of two groups living of biogeochemical zones with different levels of iodine deficiency expression has been investigated. Taking the iodinized oil during 14 days in the dose of 200 μg of iodine daily by the inhabitants of the Tissa-Danube lowland with less expressed iodine deficiency than in highlands, increases iodine dependence of the human body, decreases TSH content and the risk of goitre development, increases the excretion of iodine with urine and after a month’s taking it the mediane ioduria is achieved that corresponds to complete iodine sufficiency. Taking the IO by people constantly living in the Carpathians favours the increase of T 3 , T 4 hormone production, decreases TSH concentration to the norm in people living in better iodine ecological conditions, normalizes MMP production formation in tissues to the level of the inhabitants of lowlands and stimulates the increase of iodine with the urine.

Capacitive-discharge VUV lamp based on a water-vapor–argon mixture

Abstract: This paper presents the results of a study of the spectral characteristics of the plasma radiation (175–200 nm) of a pulse-periodic capacitive-discharge lamp that operates with a mixture of water vapor and argon. It is shown that capacitive discharge at low argon pressure is a broad-band source of vacuum ultraviolet radiation. The intensity of the emission bands of the capacitive-discharge plasma is optimized as a function of the partial pressures of argon and water vapor. The electron kinetic coefficients are calculated for a discharge in a mixture of argon and water vapor.

Early and Remote Results of Surgical Treatment of Inferior Vena Cava Thrombosis

Abstract: The objective of the research was to estimate the early and remote results of surgical treatment in patients with deep vein thrombosis of the inferior vena cava.Material and methods. The results of treating 790 patients with lower limb deep vein thrombosis and thrombosis of the inferior vena cava were analyzed. Depending on treatment, all the patients were divided into the following groups: Group IA consisted of 380 (68.5%) patients with deep vein thrombosis who underwent open complete or partial thrombectomy with or without surgical prevention of pulmonary thromboembolism; Group IB consisted of 50 (9.0%) patients with deep vein thrombosis who received combined treatment with surgical prevention of pulmonary thromboembolism; Group IC consisted of 125 (22.5%) patients with transfascial thrombosis who underwent thrombectomy of the apical thrombotic masses of deep veins followed by radical venectomy; Group II consisted of 235 (29.7%) patients with deep vein thrombosis who received conservative anticoagulant therapy only.For investigation of patients, there were used the following laboratory methods of examination: duplex ultrasound scanning, X-ray phlebography, computer tomography, echocardioscopy and radionuclide phleboscintigraphy.Results. The results of surgical and combined methods of treating deep vein thrombosis in clinical subgroups were evaluated using a three-point scale - good, satisfactory and unsatisfactory. The cumulative analysis of the results of the postoperative period during 3 years of follow-up showed that good and satisfactory results were observed in 89.3% of patients of Group IA, 81.7% of patients of Group IB, 88.4% of patients of Group IC, and 35.3% of patients of Group II. Three years after treatment, the signs of chronic venous insufficiency were found in 51.6% of patients who underwent conservative treatment, 36.4% of patients who received combined treatment, 10.2% of patients who underwent partial thrombectomy, 2.9% of patients who received surgical treatment of transfascial thrombosis; they were absent in patients who underwent radical thrombectomy.Conclusions. In quantitative evaluation of the early and remote results of treating deep vein thrombosis of the inferior vena cava, a significant improvement in the patients’ condition in all parameters was observed in the main group as compared to the control one.
