[Characteristics of Left Ventricular Diastolic Function in Patients before and after Coronary Artery Bypass Grafting].

Unlabelled: Diastolic heart dysfunction occurs essentially in patients who suffer from chronic heart failure. In this context an investigation and application of different methods for diastolic function improvement remain a priority in the therapy of cardiovascular diseases.

Objective: Our ain was to estimate coronary artery bypass grafting effect on the left ventricularfunctionality in patients with coronaty heart disease.

[The lipid metabolic characteristics of patients with thyroid pathology living in the European north of the USSR].

The blood content of total lipids, triglycerides, total cholesterol, alpha- and beta-lipoprotein cholesterol was measured in 79 patients with diffuse toxic goiter during treatment, in 25 patients with hypothyroidism, in 33 with thyroid hyperplasia, and in 54 healthy women aged 35-60 years from the group of native population of the European North. In all the forms of thyroid dysfunction, the patients manifested dyslipoproteinemia in the form of hypercholesterolemia with an increase of the concentration of beta-cholesterol, hypertriglyceridemia, and with a rise of the cholesterol atherogenic index to 4.0 and over.

[The possibilities of infrared thermography in the diagnosis of thyroid pathology].

The paper is concerned with the results of a retrospective analysis of the diagnostic value of infrared thermography of the thyroid by comparing clinical, histological (75.8% of observed cases) and thermographic diagnoses. Altogether 300 persons were examined, of them 30 were healthy subjects.

[Dynamics of interleukin 2 production in patients with diffuse toxic goiter under the influence of treatment].

The paper is devoted to the results of a study of IL-2 production by T-helpers in the course of treatment of patients with diffuse toxic goiter (DTG); 30 patients and 30 healthy controls were investigated. The diagnosis of DTG was confirmed by modern methods including radioimmunoassays. A study of the blood level (relative and absolute) of T-lymphocytes in the patients before therapy, during 2 and 12 mos.

[Lipids of blood and erythrocyte membranes in healthy persons and in patients with diffuse toxic goiter, residing in the European North of the USSR].

A study of the blood plasma content of total cholesterol in 575 healthy persons and 675 patients with diffuse toxic goiter (DTG), and the content of total lipids and triglycerides in 52 healthy persons and 132 DTG patients showed the development of adaptation hyperlipidemia in persons living long in the North. It was preserved in DTG patients irrespective of the gravity of thyrotoxicosis, stages of its therapy and the patients' age. Basing on the analysis of the level of lipid indices of erythrocytic membrane malonic dialdehyde and their refractoriness to peroxide hemolysis in 52 healthy persons and 53 DTG patients, a conclusion was made of excessive stable activation of lipid peroxidation biomembranes which can underlie the development of visceral complications.

[Interleukin 2 production in patients with thyroid diseases].

Con A-induced production of interleukin 2 was studied in peripheral blood lymphocytes obtained from 15 normal subjects and 42 patients with different thyroid diseases. It was found that thyroid diseases are accompanied by changes in IL 2 production. The level of IL 2 production by T lymphocytes is determined by the functional status of thyroid glands, their anatomy, stages of the disease and mode of treatment.
