The results of the studies on the infl uence of Selenium and Germanium nanoacqualates complex on the content of immunoglobulins and circulating immune complexes in quail’s are presented in the article. It was found that the level of immunoglobulins is the main indicator of the state of humoral immunity. According to the results of the studies the content of immunoglobulins A, M, G in the quail’s serum was 0.80 ± 0.03 mg/ml, 0.30 ± 0.01 mg/ml, and 5.82 ± 0 , 06 mg/ml, accordingly. That are 31.1%, 20.0% and 6.0%, respectively, comparing with data of the control group. Inthe serum of fi ve days old quail’s Ig A content was 0.84 ± 0.02 mg/ml, Ig M 0.54 ± 0.03 mg/ml and Ig G 6.87 ± 0.04 mg/ml, that consisted 29.2%, 42.1% and 5.0%, respectively, comparing with the control group. The content of circulating immune complexes (CEC) in theblood serum of one- and fi ve-days old quails was 1.5 and 1.6 times, respectively lower than in the birds of the control group. The content of low molecular weight CECs in the serum of one- and fi ve-days old quail, decreased signifi cantly in both groups(in 2 and 1.1 times, respectively). This probably characterizes the overall effi cacy and balance of the immune system's responses in quails exposed to Selenium and Germanium nanoacqualates at used doses of 0.05 μg/kg and 5.0 μg/kg, respectively. We consider that as a positive eff ect on the immunity of quails in the early post-embryonic period. Therefore, the use of Selenium and Germanium nanoacqualates complex has a complementary eff ect and helps to increase the immunoreactivity of young animals by maintaining the activity of the immune system. Key words: Selenium nanoacquachelate, Germanium nanoacquachelate, quails, immunoglobulins, immunity.

Immune System Response

In this paper, it is shown that the modeling process of bronchial asthma (BA ) is accompanied by changes, in comparison with the control group, in the indicators of immune system response: T- & B-lymphocytes, circulating immune complexes in blood of guinea pig males on the 4th, 18th, 25th day of experiment.The aim of the study – determination of some indices of immune system in blood of guinea pigs in the modeling process of BA on 4th, 18th, 25th day of the experiment.Materials and Methods. Experiments were conducted on 40 guinea pigs (males), with body weight 0.25–0.27 kg. Animals were divided into four groups of ten animals in each. Intact guinea pigs were the first group. Animals with experimental BA – the second, third, fourth group respectively on the 4th, 18th, 25th day of the experiment. Experimental BA was reproduced by V. I. Babych method. In blood of intact guinea pigs and animals with experimental BA , the number of T- and B-lymphocytes was determined by the method of E. F. Chernushenko, L. S. Kohosov, determination of the level of circulating immune complexes was carried out by the method of V. Haskova and co-authors. The results of the study were processed by the method of variation statistics using Student's criterion.Results and Discussion. The results of the studies showed unidirectional changes in individual parameters of the immune system, depending on the periods of the formation of BA : an increase in the number of B-lymphocytes and circulating immune complexes, a decrease in the number of T-lymphocytes for all of the studied days of the experiment.Conclusions. The obtained results indicate significant changes in the immune system parameters in the blood of experimental animals with BA and are important for understanding the pathogenesis of BA . These studies provide an opportunity to find the more perfect and effective methods of diagnosis of BA.

Aim. To assess the clinical and immunological features in patients with chronic opisthorchiasis, depending on the duration of the infection. Methods. The first group consisted of 19 patients with the duration of the infection up to 1 year, the second group consisted of 21 patients with the duration of the infection between 1 and 5 years, the third group was formed of 23 patients with the duration of the disease more than 5 years, the control group 20 healthy individuals. Immunological research was carried out at the Clinical Diagnostic Center. Statistical processing was performed using Microsoft Excel 2010 and Statistica 6.0 software. The statistical significance of differences was determined by using the MannWhitney test (U-test) at the level of significance of p 0.05. The correlations were assessed by calculating Spearman's rank correlation coefficients.Results Clinical features of chronic opisthorchiasis were revealed in the disease duration groups of up to 1 year, from 1 year to 5 years, more than 5 years: the subclinical course was most common in the group of up to 1 year; cholangiohepatitis prevailed in the group of between 1 to 5 years, allergic skin syndrome, cholangiocholecystitis and pancreatitis dominated in the group of more than 5 years. The immune response in chronic opisthorchiasis was characterized by: up to 1 year lymphocytosis, increased levels of immunoglobulins M (IgM) and circulating immune complexes (CIC), a decrease in the number of T-lymphocytes (CD3+), as well as an increase in bactericidal activity of leukocytes (BAL); between 1 and 5 years monocytosis, increased levels of immunoglobulins M, immunoglobulins G and circulating immune complexes, a decrease in T-cytotoxic lymphocytes (CD8+) and nitro blue tetrazolium (NBT test), as well as an increase in NK cells and phagocytic activity of monocytes, more than 5 years eosinophilia. Conclusion. Common features of rearrangement of the immune system in opisthorchiasis: inflammatory changes in the hemogram, activation of humoral immunity with parallel suppression of the cellular component of the immune system, and increased phagocytosis.

Burn Wounds

It is well known that the immune system is actively involved in the regeneration and healing process of burn wounds. However, unanswered questions remain about the role of humoral immunity in the mechanisms of healing and complications of burn wounds. We have developed an experimental model of the acid burns of the esophagus (ABE) corresponding esophageal burns in children 1-8 years. We studied the features of humoral immunity in rats with AВE, with the observed reduction of IgG and increase levels of medium and low circulating immune complexes (CIC) on the first day after the burn of the esophagus. On the 21st day after the burn, we observed an increase in the concentration of IgG and a slight accumulation of medium- and low-CIC. Studied indicators can be used for the differentiation of ABE.

SummaryOne hundred patients were included in a randomized open trial to assess the systemic factor Xa (FXa) and thrombin inhibitory effect as well as the safety profile of low molecular weight heparin (LMWH) given subcutaneously in conjunction with streptokinase (SK) in patients with acute myocardial infarction (MI). The treatment was initiated prior to SK, followed by repeated injections every 12 h for 7 days, using a dose of 150 anti-Xa units per kg body weight. The control group received unfractionated heparin (UFH) 12,500 IU subcutaneously every 12 h for 7 days, initiated 4 h after start of SK infusion. All patients received acetylsalicylic acid (ASA) initiated prior to SK.Serial blood samples were collected prior to and during the first 24 h after initiation of SK infusion for determination of prothrombin fragment 1+2 (Fl+2), thrombin-antithrombin III (TAT) complexes, fibrinopeptide A (FPA) and cardiac enzymes. Bleeding complications and adverse events were carefully accounted for.Infarct characteristics, as judged by creatine kinase MB isoenzyme (CK-MB) and cardiac troponin T (cTnT), were similar in both groups of patients.A comparable transient increase in Fl+2, TAT and FPA was noted irrespective of heparin regimen. Increased anti-Xa activity in patients given LMWH prior to thrombolytic treatment had no impact on indices of systemic thrombin activation.The incidence of major bleedings was significantly higher in patients receiving LMWH as compared to patients receiving UFH. However, the occurrence of bleedings was modified after reduction of the initial LMWH dose to 100 anti-Xa units per kg body weight.In conclusion, systemic FXa- and thrombin activity following SK-infusion in patients with acute MI was uninfluenced by conjunctive LMWH treatment.

AbstractSpirulina platensis protein hydrolysates were prepared by digesting protein extracts with papain, and the hydrolysates were separated into 30, 10, and 3 kDa weights using membrane ultrafiltration. The 0–3 kDa low-molecular-weight Spirulina peptides (LMWSPs) proved the highest chemical antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging ability, hydroxyl radical (·OH) scavenging activities and total antioxidant capacity. Cellular antioxidant ability of LMWPs fractions against 2000 μg/mL H2O2 induced oxidative damage of L02 cells were investigated. The MTT assay results displayed that LMWSPs at different concentrations (0–1000 μg/mL) had proliferation effect on the L02 cells and that treatment of the L02 cells with the 1000 μg/mL LMWSPs (0–3 kDa) significantly prevented H2O2-induced oxidative damage compared with control cells. Moreover, the 2′,7′-dichlorofluorescein diacetate (DCFH-DA) fluorescent probe assay showed that the levels of ROS and NO were significantly lower in the experimental group that was treated with the peptides for 24 h than in the control group. Furthermore, using the corresponding kits, the treatment inhibited the reduction of SOD activity and the increase of MDA contents in the L02 cells. Therefore, LMWSPs (0–3 kDa) may have potential applications in antioxidant and liver health products.

The research aimed to determine the effect of a mixture of low molecular weight organic acids and complex phytobiotics when replacing a feed antibiotic with them on the activity of digestive enzymes in the duode-nal chyme and the activity of pancreatic enzymes in the blood plasma of young stock B5 and B9 meat chicken lines. The experiments were carried out on the original lines of meat poultry lines B5 (Cornish) and B9 (Plymouth rock). There was an operation to insert a cannula into the duodenum at the age of 6 weeks. The enzymatic activity of the duodenum chyme and the content of pancreatic enzymes in the blood plasma in the groups of chickens receiving antibiotics, low molecular weight organic acids, and phytobiotics with the diet. The data showed that the influence of feed additives on the physiological status of poultry was different. The use of low molecular weight organic acids of the B5 and B9 chicken lines had a significant effect on the production of digestive enzymes due to an increase in the activity of chyme lipase (by 98.3%) and blood plasma lipase (by 26.6%) in B9 chickens and an increase in chyme proteases (by 30.9%) in B5 chickens compared with the control group, where the antibiotic was used. The introduction of complex phytobiotics into the diet had a negative effect on chickens of the B5 line (Cornish), reducing the activity of amylase and lipase of the duodenal chyme (by 29.2 and 26.9%) compared with the control group. In B9 (Plymouth rock) chickens, only the chyme amylase activity increased by 30.8% that indicates an improvement in the availability of feed carbohydrates. These data confirm the need to take into account the different effects of feed additives on the digestion processes in different poultry crosses.

The influence of the chronopharmacological scheme of treatment with the use of exogenous Melatonin in the form of the Melaksen drug on the immunity status of psoriasis patients has been studied. The study of the immunity status consisted in determination of the main Manchini classes of immunoglobulins A, M, G, the level of circulating immune complexes by the method of selective precipitation in 3% polyethylene glycol. In addition, we determined the subpopulation of lymphocytes carrying CD3, CD4, CD8, CD16, CD 25, and CD72 antigens by the immunofluorescent method. In has been found that Melatonin in psoriasis patients exerts the immunomodulatory action on the immune system at the combined treatment (due to an increase in the number of -lymphocytes with cytotoxic-suppressive properties at obvious signs of immune disbalance in the form of the increased ratio of Т CD4+ and CD8+).

Aim. The paper studies the dynamics of the indicators defi ning the antioxidant system (AOS) and endogenous intoxication in patients with microbial eczema (ME) prior to and following treatment.Materials and methods. The experimental group consisted of patients with ME (n=30) and the control group comprising somatically healthy individuals (n=30). In this study, we determined the components of the antioxidant defence system in blood plasma and erythrocyte suspension, as well as assessed endogenous intoxication.Results. The study revealed an imbalance of indicators refl ecting the severity of oxidative stress and endogenous intoxication in patients suffering from ME. Prior to receiving treatment, the experimental group, as compared to the control group, exhibited an increase in catalase activity (CAT) up to 35.93 [32.50; 38.22] mmol / (min • l) (p < 0.001) and glutathione peroxidase (GPx) up to 1194.27 [1069.50; 1375.78] μmol / (min • l) (p < 0.001). In addition, there was a decrease in the activity of superoxide dismutase (SOD) to 13.28 [11.35; 14.10] u/l (p < 0.001), glutathione reductase (GR) to 501.46 [479.77; 542.52] mmol / (min • l) (p < 0.001) and the concentration of reduced glutathione to 1.64 [1.59; 1.78] μmol / ml (p = 0.043). We observed no statistically signifi cant changes in the total antioxidant activity (TAA) of blood plasma (0.59 [0.55;0.62] mg/l; р = 0.375) and the sulphhydryl groups (0.44 [0.41;0.47] ODU; р =0.111). The patients with ME exhibited the syndrome of endogenous intoxication (SEI), accompanied by an increase in the content of medium and low molecular weight molecules in plasma to 12.19 [11.20; 13.37] arb. u. (p < 0.001), with their content in erythrocytes being relatively normal – 15.23 [14.26; 16.44] arb. u. (p = 0.005). Following the treatment, changes in the studied parameters were of a multidirectional character in relation to the control values. An increased level of CAT and GPx (р <0,001), as well as lower values of SOD and GR, continued to be observed (р < 0.001). The TAA in serum (p = 0.308), sulphhydryl groups (p = 0.111) and reduced glutathione (p = 0.107) did not differ signifi cantly from the control values. The treatment did not reverse the SEI: the content of medium and low molecular weight molecules continued to increase in both plasma and erythrocytes, as compared to the control values (p < 0.001 in both cases).Conclusion. The obtained data confi rm the failure of mechanisms underlying antioxidant defence in patients with ME. Despite the attempt of its compensation by increasing the catalase activity, SOD control values were still not reached. An increase in the GPx activity along with a decrease in GR was observed, which could have lead, in turn, to a decrease in the concentration of reduced glutathione. The failure of the antioxidant defence mechanisms is also indicated by an increase in the content of medium and low molecular weight molecules, as well as by the development of the SEI, resulting from the excessive formation of reactive oxygen species and the inability of the antioxidant system to neutralise them.
