The article presents the results of research on the parameters of cellular metabolism in 141 horses. Studies were conducted in one of the unsuccessful with leptospirosis equine farm. The kits of the company «Reagent» (Dnipropetrovsk) in blood serum determined the content of such acute phase proteins as ceruloplasmin by the method of Ravin, haptoglobin by reaction with rivanolol, total protein by biuretovoy reaction, albumin by reaction with bromocresol green by methods K.M. Veremeenko et al. (1988). The concentration of nitrites was determined by the interaction of plasma nitrides with the Grice reagent, and the colored complex was colorimetricized using a spectrophotometer at a wavelength of 540 nm using the method of Grand F. et. al. (2001) in the modification of Golikov P.P. (2004). The production and recording of PMA and lysis was carried out in accordance with the «Manual on Laboratory Diagnosis of Leptospirosis» (1997). The reaction of the RDP for the diagnosis of rhinopneumonia of horses was carried out in accordance with the methodological recommendations (2009). The first group (control) was represented by 49 clinically healthy serologically negative in the reaction of microagglutination (PMA) and diffusion precipitation (RDP) reactions with respect to leptospirosis and rhinopneumonia. The second group with latent course of leptospirosis included 51 horses. The third group with latent course of leptospirosis and rhinopneumonia included 41 horses. As a result of our research, we established a significant increase (P < 0.05–0.01) of nitric oxide to 65.73 ± 4.43 and 55.86 ± 2.71 μmol/l in 2–3 groups in comparison with healthy. There is also a significant increase in ceruloplasmin (P < 0.01–0.001) to 216.35 ± 11.43, 243.15 ± 19.34 mg/l in 2–3 groups in comparison with a healthy one. The content of hapthoglobin, on the contrary, decreases to 0.61 ± 0.03 and 0.52 ± 0.04 * g / l in 2–3 groups compared with healthy. Albumin content did not differ significantly in the studied groups. At the same time, a significant reduction of fibrinogen (P < 0.01–0.001) was established to 1.23 ± 0.09 and 1.22 ± 0.08 g/l in 2–3 groups in comparison with healthy ones. The content of soluble fibrin (P < 0.001) to 16.05 ± 0.31 and 21.22 ± 0.71 mg/% in 2–3 groups in comparison with healthy is significantly increased. In a coherent latent course of leptospirosis and rhinopneumonia in horses as markers for assessing the state of immunobiological reactivity of an organism it is advisable to determine the content of nitric oxide, ceruloplasmin, soluble fibrin, fibrinogen and haptoglobin in blood serum. The results obtained are analyzed for the expediency of conducting a course of intensive care for especially valuable horses.

The blood test allows you to give an objective assessment of the state of health of animals and timely identify changes occurring in the body. To assess the content of albumins in the blood serum, the method of measuring the dynamic surface tension on the VRA-1P device, which works according to the method of maximum pressure in the bubble, was used. Based on the results of the measurements, a mathematical model was proposed, and using the regression analysis method, formulas for determining the concentration of albumins were developed, which showed good convergence with other measurement methods.

Introduction. Activation of lipid peroxidation is one of the trigger mechanisms of periodontium injury, which is primary caused by cellular damage. Reactive oxygen and nitrogen species (RONS) are able to cause damage to a cell as well as final products of lipid peroxidation, including unsaturated aldehydes and other metabolites. Objective. The aim of the research was to determine the role of RONS and accumulation of lipid peroxidation derivatives in initial development and formation of chronical inflammatory process in periodontium. Methods. Experimental periodontitis was modeled in animals by injection of complex mixtures of microorganisms diluted in egg protein into periodontal tissues. The results of biochemical studies of free radical processes activity in blood serum were evaluated by content of diene, triene conjugates, TBA-active products and total quantity of metabolites of nitric oxide (NO2–+NO3–), which were determined on the 7th, 14th and 30th days of the experiment. Results. Generation of active forms of oxygen is more influential, providing longevity of inflammatory process. This pays attention to typical dynamics of changes in active processes of lipid peroxidation in the development and course of experimental periodontitis. The study of inflammatory process with a bacterial-immune component in the rats’ periodontal complex proved accumulation of lipid peroxidation and nitric oxide metabolites in blood serum.Conclusions. The preservation of increased lipid peroxidation and nitric oxide metabolites in blood serum of the experimental animals with acute periodontitis conduce enhance of alteration and delayed healing that result in its sequel into chronical periodontitis.

Objective. To determine the blood serum 2-microglobulin and 2-macroglobulin concentration in patients undergoing renal replacement therapy (programmed hemodialysis) for the diagnosis of uremic pancreatitis and / or destructive pancreatitis. Materials and methods. The study involved 52 patients admitted to the Surgical Unit of Astrakhan "RZhD-Medicine" Hospital and City Clinical Hospital № 3. The blood serum 2-microglobulin and 2-macroglobulin concentration was analyzed in patients admitted on an emergency basis with suspicion of uremic pancreatitis and destructive pancreatitis, who receive renal replacement therapy (programmed hemodialysis). The control group included 50 outpatients undergoing renal replacement therapy (programmed hemodialysis). The study did not include patients with suspected pancreatitis who were not receiving renal replacement therapy. The period of the study is 20192021. Results. The concentration of blood serum 2-microglobulin is statistically higher than normal in all patients, who had received renal replacement therapy (programmed hemodialysis) in anamnesis. The most statistically high concentration of 2-microglobulin was revealed while studying patients with uremic pancreatitis (n = 34), and was (30.0 2.75 mg/l) compared with the blood serum concentration in patients with destructive pancreatitis (8 0.51 mg / l). The concentration of 2-macroglobulin was statistically lower in destructive pancreatitis (n = 18) and was 615 161 mg/l compared with uremic pancreatitis (980 216 mg/l). In the control group of outpatients (n = 50) receiving renal replacement therapy (programmed hemodialysis), no statistically significant blood serum concentrations of 2-microglobulin and 2-macroglobulin were found. Conclusions. A clear dependence of the concentration of 2-microglobulin and 2-macroglobulin on the severity of uremic pancreatitis and destructive pancreatitis was established. Statistically high values of 2-microglobulin concentrations were obtained in patients with uremic pancreatitis, and the 2-macroglobulin level was statistically low in destructive pancreatitis.

<p><strong>Background.</strong> Nitric oxide (NO) is an important mediator of hepatotoxicity. NO in liver can be derived from two sources: (1) constitutive NO synthase (eNOS) in endothelial cells, and (2) inducible NO synthase (iNOS) in hepatocytes and Kupffer cells.<br /><strong>Objectives.</strong> The present study was aimed to examine the effect of nonselective NOS inhibitor (L-NAME) and selective iNOS inhibitor (1400W) on the development of allyl alcohol (AA) induced hepatitis in rats.<br /><strong>Methods.</strong> Male Wistar rats were treated with intraperitoneal injection of saline or AA and L-NAME or 1400W. NO in liver was measured by electrochemical method after eNOS stimulation by calcium ionophore. Total NOS activity and nitrite/nitrate content were measured in liver and blood serum. The activity of free radical oxidation in liver was measured by chemiluminescent method. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were assayed in blood serum<br /><strong>Results.</strong> AA increased the activity of free radical processes in liver and markers of cytolysis in serum, as well as decreased eNOS and increased iNOS activities. L-NAME considerably inhibited eNOS and augmented the necrosogenic properties of AA, whereas 1400W partially prevented liver damage.<br /><strong>Conclusion.</strong> It has been concluded that in AA intoxication NO produced from eNOS is beneficial to the liver, but NO derived from the upregulated iNOS has deleterious effect.</p><p><strong>KEY WORDS:</strong> nitric oxide, toxic hepatitis, NOS inhibitors.<br /><br /></p>

Diseases of the gastrointestinal tract of horses are caused by many factors and have a complex pathogenesis. Developing effective methods of differential diagnostics is of high fundamental and applied importance. The pathogenesis of diseases of the digestive tract of horses accompanied by the development of inflammation and oxidative stress, can be associated with a lack of the nitrogen monoxide which controls many signaling pathways in the body. The level of the nitric oxide (NO) is involved in the regulation of the immune and nervous systems, the tone of all the blood vessels, and the courses of many pathological processes. The nitric oxide activates guanylate cyclase (sGC) and leads to vascular relaxation. The aim of this investigation was to study the metabolites of nitric oxide in horses suffered from intestinal diseases. The levels of nitric oxide in the blood serum of horses depending on their age and health state was studied. The concentration of nitrites in the blood serum of horses aged 6–25 years was 3.4 ± 4.2 μM, and in the young horses (1–5 years) the level of this indicator was 8.2 ± 5.4 μM. A sharp decrease in nitrite was observed in all the horses with intestinal diseases of 2 ± 0.9 μM, especially with tympanitic caecun of 0.6 ± 0.4 μM and with spasmodic colic of 1.8 ± 0.5 μM. The level of nitrosylhemoglobin HbNO in the blood of the diseased animals was higher than that in clinically healthy horses, regardless of age.

AbstractBackground:Colorimetric albumin assays based on binding to bromocresol purple (BCP) and bromocresol green (BCG) yield different results in chronic kidney disease. Altered dye binding of carbamylated albumin has been suggested as a cause. In the present study, a detailed analysis was carried out in which uremic toxins, acute phase proteins and Kt/V, a parameter describing hemodialysis efficiency, were compared with colorimetrically assayed (BCP and BCG) serum albumin.Methods:Albumin was assayed using immunonephelometry on a BN II nephelometer and colorimetrically based on, respectively, BCP and BCG on a Modular P analyzer. Uremic toxins were assessed using high-performance liquid chromatography. Acute phase proteins (C-reactive protein and α1-acid glycoprotein) and plasma protein α2-macroglobulin were assayed nephelometrically. In parallel, Kt/V was calculated.Results:Sixty-two serum specimens originating from hemodialysis patients were analyzed. Among the uremic toxins investigated, total para-cresyl sulfate (PCS) showed a significant positive correlation with the BCP/BCG ratio. The serum α1-acid glycoprotein concentration correlated negatively with the BCP/BCG ratio. The BCP/BCG ratio showed also a negative correlation with Kt/V.Conclusions:In renal insufficiency, the BCP/BCG ratio of serum albumin is affected by multiple factors: next to carbamylation, uremic toxins (total PCS) and α1-acid glycoprotein also play a role.

Harmful Effects

The influence of zearalenone on blood serum protein status and the feasibility of utilizing a modified clinoptilolite and esterified glucomannan to alleviate its harmful effects was examined in two trials, 31 and 29 days long, conducted on a total of 64 pigs (32 each) 60 days old, divided into four groups, each containing 8 pigs. Control groups (K) received noncontaminated feed, while experimental groups received feed supplemented with 3.84 mg/kg in the first trial and 5.12 mg/kg of zearalenone in the second trial. Pigs in the first experimental groups (O-I) were given feed with toxin only. Modified clinoptilolite in the amount of 0.2% and esterified glucomannan in the amount of 0.1% were introduced in contaminated feed of the second (O-II) and the third experimental groups (O-III) of both trials. With the use of contaminated feed, a declining trend of the A/G ratio was observed: decrease of albumin content and increase of globulin content on account of the _ globulin fraction. A decrease of the _ globulin fraction was detected at the same time. Total protein concentration was also lower. The application of adsorbents successfully alleviated harmful effects of the F-2 toxin on the affected biochemical parameters in blood serum.
