[Genetically determined gout: characteristics of the course].

Analysis of clinical-roentgen-laboratory features of the course of hereditarily determined gout in 74 patients is represented. It is exhibited that hereditarily induced gout begins at the young age and is accompanied by the acute disturbance of purine exchange resulting in serious relapsing course of the articular (with availability of radiological attributes of osteal destruction) and the renal syndromes (urate nephrolithiasis, immune complex glomerulonephritis, tubulointerstitional nephritis) as well as in the early occurrence and rapidly progressing chronic renal insufficiency. The disease is accompanied by high frequency of the cardiovascular pathologies negatively influencing the mean lifetime of patients.

[Hyperuricemia and disorders in content of amino acids-purine precursors in patients with autoimmune diseases and gout].

Patients with system lupus erythematosus, rheumatic arthritis, chronic active hepatitis and gout were found to have considerable hyperuricemia and be decreased in aminoacides content, which are the predecessors of purine. Hyperactivity of xanthineoxidase and POL content were also revealed. The close correlation relation of purine indices of such patients has been observed.

[Roentgenologic assessment of articular lesions in rheumatoid arthritis].

The article presents a comparative analysis of methods for quantitative assessment of roengenologic changes in the joints in rheumatoid arthritis that have come to be widely used in USA and Europe. It is noted that the Steinbroker's method widely employed by clinicians fails to give an integral assessment of the articular affection. Expediency is documented of employment of the Sharp's method in roentgenologic monitoring in clinical trials of new antirheumatic drug preparations.

[Physical and chemical properties of the condensate of breathed-out air in healthy people].

The physical-and-chemical condition of condensate of breathed-out moisture (CBM) was studied by the computer-aided analysis of axis-symmetric drops' form in healthy subjects; such condition was found to depend on sex, age and smoking-addiction of the examined persons. The surface tension of the mentioned moisture correlated with its viscoelastic index and with relaxation. The metabolites of nitric oxide, lipids, urea, lactic acid (not uric acid) and of hydrogen peroxide were found to influence the physical-and-chemical parameters of respiratory moisture.

[The blood level of nitric oxide metabolites in experimental autoimmune disease during immunosuppressive therapy].

Experimental autoimmune disease causes a drastic increase in the production of nitric oxide metabolites. The latter correlate with the indices of autoimmunity expression, with the levels of cyclic nucleotides, with the severity of morphological impairment of the structures of immunocompetent organs. The use of immunosuppressive agents in the pathogenetic therapy of an autoimmune process normalizes both the blood levels of nitrites/nitrates and immunological parameters; this reflects a clear-cut relationship between the synthesis of nitric oxide and the immune response of the body.

[Dynamic interphasic tensimetry of blood and urine in systemic lupus erythemotosus].

Aim: To study dynamic surface tension (DST) of blood and urine in SLE patients.

Materials And Methods: Clinical, immunological examinations, DST of blood and urine using computer tensiometers were made in 67 SLE patients aged 15 to 62 years.

Results: Changes in interphasic tensiograms in males and females were characterized regarding the course, activity of the pathological process and the presence of certain clinical symptoms.

[Dynamic surface tension of blood in chronic dust bronchitis in coal mines workers].

Chronic dust bronchitis in miners is associated with increase in dynamic surface tension of blood at short (t = 0.01 s) and medium (t = 1 s) surface lifetimes with lower declination angle of interphase tensiograms curve. Surface tension disorders were similar to those in experimental dust bronchitis.

[Systemic enzyme therapy in chronic glomerulonephritis].

Aim: To try polyenzyme drug vobenzim in chronic glomerulonephritis (CGN).

Materials And Methods: 174 CGN patients were randomized into 2 groups. The study group of 39 patients received conventional pathogenetic treatment plus vobenzim (initial dose 18-24, maintenance 12-15 dragees a day).

[Pulmonary surfactant status in experimental dust-induced bronchitis based on the data from dynamic interphase tensiometry].

The disease was simulated by inhalation of dust containing 29% of free silica in Wistar male rats during 8 months. One group of the subjects was kept under 26-28 degrees C and other one--under 38-40 degrees C. Dynamic surface tension of lung tissue homogenate was studied by means of computer tensiometer MRT (Lauda, Germany).

[Changes in the dynamic surface tension of the blood and urine during the development of visceritis in patients with rheumatoid arthritis].

The condition was studied of the dynamic surface tension of biologic fluids in patients with rheumatoid arthritis using a method of maximum pressure in the vesicle with the aid of computerized tensiometer MPT-1 "Lauda" (Germany). Rise in indices of blood serum surface tension with diminution of the slope of tensiogram curves may suggest the development of pathology of the heart and liver, while increase in the same parameters of urine might be indicative of the coming nephropathy.

[Dynamic interphase tensiometry of the cerebrospinal fluid and blood serum in nervous system tumors].

Dynamic superficial tension (ST) of spinal fluid (SF) and blood serum in patients with CNS tumors was investigated. The maximum bubble tension was measured by a MPT2 computer tensiometer (LAUDA). There were decreases in ST of blood serum at t = 1 and t-->infinity, increases in ST at t = 0.

[Dynamic middle-phase tensiometry of blood and urine in female patients with malignant tumors of the reproductive organs].

An improved version of the MPT2 (LAUDA) computerized tensiometer (Germany) was used to measure dynamic surface tension (ST) of blood and urine by the maximum bubble pressure method in patients with tumors of the uterus, vagina and cervical canal. Relatively low blood and urine ST values at t-->infinity and serum at t = 1 s were registered. Combined radiotherapy involved oppositely-directed changes in the equilibrium (static) ST of the biological fluids as well as a urine ST inhibition in the surface short-life range (t = 0.

[Effect on cardiac function of altered adenosine metabolism in rat brain structures in modelled hyperuricemia].

Experiments on 24 Wistar male rats were performed to clarify the role of central mechanisms in the onset of electrical instability of the heart due to disturbances in purine metabolism. The activity of the enzymes responsible for synthesis and conversion of adenosine-5-nucleotidase and adenosine deaminase in the sensomotor cortex, hypothalamus and hippocamp was studied. Changes in cardiac function were most severe in high levels of adenosine in the neurons of the sensomotor cortex, hypothalamus and hippocamp.

[Biogenic amines in rat brain structures in an adjuvant arthritis model].

The role of changes in biogenic amines neurochemistry in cerebral structures in abnormal immunoreactivity accompanying development of autoimmune disease was investigated in experiments on 24 Wistar male rats. Biogenic amines and their metabolites (dopamine, dioxyphenylacetic acid, serotonin, oxyindolacetic acid) were assays in the sensomotor cortex, hypothalamus and hippocamp by means of high-performance liquid chromatography. Development of adjuvant arthritis was associated with definite neurochemical changes in the brain: inhibition of serotonin metabolism and enhancement of dopaminergic systems in the hypothalamus and sensomotor cortex.

[Dynamic surface tension of blood and synovial fluid in rheumatoid arthritis].

Aim: Assessment of the dynamic surface tension (DST) of blood serum (BS), synovial fluid (SF) in various courses of rheumatoid arthritis (RA).

Materials And Methods: Forty three patients with RA and 63 apparently healthy individuals were examined. DST of BS and SF was determined in the computer-aided tensiometer and some blood biochemical parameters were also measured.

[The dynamic surface tension of the blood and urine in chronic glomerulonephritis].

Dynamic surface-tension (S-T) was investigated of blood and urine of healthy individuals and patients with chronic glomerulonephritis by the proposed method of maximum pressure in a bubble with the aid of the computer-assisted device tensometer MPT-1 (Lauda, Germany). Patterns of changes in dynamic and static S-T were found out as were those of the slope of the curve in patients with mesangioproliferative and mesangiocapillary variants of the condition, in nephrotic syndrome and chronic renal insufficiency. Correlation type comparison was performed of physical-and-chemical properties of biological fluids to parameters characterizing protein and fat exchange.

[Sex and gonadotropic hormones in the blood in joint diseases in miners].

Coal miners suffering from rheumatoid arthritis (RA), deforming osteoarthrosis (OA) and gouty arthritis (GA) were found to develop hypotestosteronemia in a study on the condition of the hypophysis-and-gonads system, this being observed even in essentially healthy individuals. With all arthronoses, androgen levels get depressed, particularly so in the presence of increased activity of lutropin. In RA examenees blood concentration of estradiol tends to increase, while OA and GA miners demonstrate reduced content of estrogen, with manifest hyperprogesteronemia being common.

[Changes in calcium metabolism in osteoarthrosis in miners].

The studies covered serum levels of total and ionized calcium (Ca), parathyroid hormone (PTH), calcitriol (Ctr) and calcitonin (Ct) in miners assigned to various occupational groups and suffering from deforming osteoarthrosis. Ratio of calcium clearance to glomerular filtration rate was assessed. Ionized Ca appeared to decrease along with increase of PTH and Ctr.

[Immune disorders in osteoarthrosis in miners].

An immunologic evaluation was done in healthy miners and those working in coal mines suffering from deforming osteoarthrosis. Blood levels of beta 2-microglobulin and circulating immune complexes, titres of antibodies to glycosaminoglycans and antigens from cartilaginous tissue and synovial membrane were all found to be elevated. Shifts in the immunity system were clearly related to the spread of the pathological process as well as the rate of the disease progression and presence of reactive synovitis but not with occupation of the patients.

[Hypophyseal gonadotropic function in gout].

Gonadotropic function of hypophysis was studied in 109 patients with gout. Raised level of luteinizing hormone (LH) was found in men while women had decreased content of LH and follicle-stimulating hormone (FSH). Severe lesions of joins and kidneys were associated with suppressed FSH secretion.
