[Eritropoetin as laboratory index of the degree of respiratory insufficiency in chronic obstructive pulmonary diseases.].

he concentration of erythropoietin (EPO) in serum was studied. The study included 122 people divided into two groups. The main group (group 1) consisted of 102 patients with chronic obstructive pulmonary disease (COPD).

[Ejaculate and serum procalcitonin levels in healthy men and men with oligoasthenozoospermia].

Introduction: Seminal plasma composition reflects the activity of reproductive organs involved in the semen production.

Aim: To study procalcitonin concentrations in serum and semen samples of healthy men and men with oligoasthenozoospermia.

Method: s .

[The concentration of cerebral natriuretic peptide in tear and blood serum.].

The natriuretic peptides regulate pressure and water metabolism in human organism. The concentration of N-thermal cerebral natriuretic propeptide (NT-proBNP) in tear and blood serum was analyzed. The sampling included 49 patients divided on three groups.

[The relationship between content of malonic aldehyde, activity of glutathione peroxidase and polymorphism of gene GPX4 (718C/T) under chronic hepatitis C].

The study was carried out to evaluate concentration of malonic dialdehyde and activity of glutathione peroxidase in blood serum in their relationship with biochemical tests of functional conditions of liver; data of fibroelastography and polymorphism of gene GPX4 (718C/T) in patients with chronic hepatitis C. The sampling consisted of 100 patients with chronic hepatitis C. The control group included 80 healthy donors.

[The concentration of procalcitonin in blood andi enteric exudation in patients at early post-operation period].

The study sampling included 46 patients operated on the occasion of acute surgical pathology of abdominal organs. The concentration of procalcitonin was analyzed at 2-3 days after operation in simultaneously obtained samples of blood serum and exudation of small intestine. The level of procalcitonin was analyzed using enzyme-linked immunosorbent assay with test-systems with sensitivity 0.

[Catalase gene rs1001179 polymorphism and oxidative stress in patients with chronic hepatitis C and ulcerative colitis].

Aim: To study the rs1001179 polymorphism of the catalase (CAT) gene and to estimate the serum levels of the enzymes catalase and glutathione peroxidase (GP) in patients with chronic hepatitis C (CHC) and in those with ulcerative colitis (UC) in the Perm Territory.

Subjects And Methods: Ninety patients with reactivation-phase CHC and 50 patients with exacerbation-phase UC were examined. The serum levels of catalase and GP were determined and the polymorphic variants of the marker of CAT gene rs1001179 in the DNA isolated from whole blood were found in all the patients.

[The value of immune enzyme testing of qualitative content of blood serotonin and liquor, in differentiate diagnostic of craniocerebral injury].

The sample of 72 patients with craniocerebral injury of light and medium degree in acute period was used to study the content of serotonin in blood serum and spinal liquor. The increase of the level of serotonin in blood serum depending on degree of severity of trauma was established. This occurrence can be used as a technique of differential diagnostic of concussion and contusion of brain.

[The impact of blood smear preparation on effectiveness of functioning of Vision Hema--the digital system of automatic blood analysis].

The article deals with study of the impact of standardization of blood smears preparation on effectiveness of functioning of Vision Hema system. The analysis was applied to the results of counting of 200 leukocytes in 30 blood smears prepared from venous blood stabilized with ethylenediaminetetraacetic acid using thoroughly degreased slide plates and applying automatic device to prepare blood smears (comparative group) and in 49 preparations prepared manually from non-stabilized capillary blood (control group). The standardization of the procedure of preparation of glass samples resulted in five time decrease of total amount of artifacts and in disappearance of thrombocytes aggregates and pavement epithelium cells.

[Chemiluminescence analysis of biological fluids in patients with diabetes mellitus].

Chemiluminescence analysis (CA) was made for different biological fluids in 50 patients with diabetes mellitus (DM). Intensified chemiluminescence of erythrocytes, blood serum, urine and tear is indicative of an enhanced free-radical oxidation in diabetes mellitus. CA of biological fluids made in DM patients reflects a disease severity.

[Novel methods in diabetes mellitus diagnosis].

Analysis of the lacrimal fluid was carried out for the diagnosis of diabetes mellitus in 68 patients. Collection of tears is absolutely painless, atraumatic, and involves virtually no risk of viral infections. Analysis of the lacrimal fluid is particularly valuable for repeated analyses over the course of disease.

[Diagnosis of endocardial electrode microdislocation at endocardial pacing].

Signs of microdislocation of an endocardial electrode (EE) were observed in 56 (14.4%) of 390 patients with an implantable pacemaker in the postoperative period. The microdislocation was diagnosed from electrocardiographic evidence for no response of a pacing pulse and from fluctuations in the pacing threshold, and from X-ray findings of the thickened and ill-defined outlines of a distal EE with preserving cardiac stimulation.

[The runaway pacemaker syndrome during electrical ventricular stimulation of the heart].

The paper reports a case of escaping pacemaker syndrome in a female with continuous endocardial ventricular pacing. The syndrome was provoked by defects in the electronic scheme because of weakening of pacemaker's battery.

[Fixation of the endocardial electrode in cardiac pacing].

The late outcomes of continuous endocardial pacing surgery were studied in 34 patients when various approaches were used to fix a proximal endocardial electrode. When fixed to a vein or its adjacent tissues, the electrode remained to be stable while raising hands. When fixed to the cephalic vein, this procedure was accompanied by the displacement of the endocardial electrode and the appearance of X-ray signs of electrode instability.
