The aim of the research. To evaluate the effectiveness of synthetic low-molecular interferon inducers in children with Epstein-Barr viral infection. Material and methods. The study included 68 children aged 7 to 17 years with primary Epstein-Barr viral infection: 38 children in the main group received basic therapy against the primary form of Epstein-Barr viral infection in age-specific dosages in combination with a synthetic low-molecular interferon inducer; 30 children of the control group received the conventional basic therapy with age-specific dosages. Results. It has been established that clinical manifestation of Epstein-Barr viral infection is based on immunopathological inflammation mediated by the factors of cellular immunity. As a result of the therapy, 78.95 % of children in the main group had a normal rate of functional recovery of the liver. In the control group, however, the recovery was delayed in 60.00 % of children: rapid recovery was only noted in the main group. Administration of synthetic lowmolecular weight interferon inducers in addition to basic symptomatic therapy facilitated the reduction of intoxication symptoms duration by 4.7±1.9 days (p < 0.05) and the duration of the icteric period by 5.3±0.9 days (p < 0.05), as well as 5.1±1.3 days earlier normalisation of liver size (p < 0.05). Conclusion. Thus, the use of synthetic low molecular weight interferon inducers in combination with basic therapy against the primary form of Epstein-Barr viral infection in children contributes to a faster restoration of the functional state of the liver. The conducted clinical and biochemical studies indicate high efficiency of synthetic low molecular weight interferon inducers in the complex therapy of Epstein-Barr viral infection in children.

Objective. To assess the efficacy and safety of low molecular weight sugar solution as a hepatoprotector in the first trimester of pregnancy in patients with liver functional disorders against the background of early toxicosis and / or hepatotoxicity. Patients and methods. The study included 70 patients: the main group (n = 30) – pregnant women with functional hepatopathies who received therapy with drug Heptrong; the control group (n = 30) – pregnant women who received standard treatment, of which 15 patients had hepatotoxicity (essential phospholipid therapy) and 15 patients with early toxicosis (intravenous saline fluid therapy, Cerucal), as well as 10 pregnant women with early toxicosis who were treated without drugs (the placebo group). Results. Pregnant women with early toxicosis noted a decrease in its clinical manifestations against the use of the drug Heptrong after 2.3 ± 0.8 days from the onset of therapy; by the end of therapy, all patients had no vomiting, and nausea stopped in 80%, which was not observed in comparison groups. The normalization of alanine aminotransferase (≤40 U/L) occurred in 80% of pregnant women in the main group (p < 0.01) and in 66% (p < 0.01) when treating with essential phospholipids. The normalization of alanine aminotransferase (≤40 U/L) occurred in 90% (p < 0.01) and 33.3% (p = 0.03), respectively. A significant decrease in the level of bile acids (from 8.49 ± 2.1 μmol/L to 2.74 ± 1.1 μmol/L; p < 0.05) and improvement in the indicators of the antioxidant system – an increase in total antiradical activity (from 804.0.0 ± 10.5 μmol/L to 839.0 ± 11.0 μmol/L; p < 0.05) and a decrease in the level of conjugated dienes (from 3.77 ± 0.2 μmol/L to 3.26 ± ± 0.1 μmol/L; p < 0.05) – were observed only in the main group. A number of other indicators of the “liver panel” tended to improve only in the main group. Conclusion. Heptrong is an effective hepatoprotective drug, which considerably improves the state of pregnant women during early toxicosis and helps to reduce liver transaminases and bile acids in pregnant women with hepatotoxicity. Due to the antiinflammatory and pronounced antioxidant effect, which is not observed in standard pharmacological treatment, Heptrong can be used to prevent late obstetric complications. Key words: Heptrong, drug-induced hepatopathies, “liver panel” indicators, early toxicosis

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.

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.

The prophylactic antithrombotic efficacy of a low molecular weight heparin was compared with a traditional unfractionated calcium heparin after orthopaedic surgery in 140 patients. Deep vein thromboses were detected in legs either by Doppler sonography or [125I]fibrinogen uptake tests in five (7.1%) and seven (10%) patients, respectively. The capacity of both drugs to prevent deep vein thrombosis was demonstrated. Compared with the control group, those who used low molecular weight heparin showed a significant increase of activated factor X inhibition and smaller increases in activated partial thromboplastin times. Tolerability of both drugs was good, with a low incidence of local side-effects.

Zearalenone is a toxic low-molecular-weight molecule that is naturally produced by moulds on crops as a secondary metabolite. The aim of this study was to determine the genotoxicity of caecal water collected successively from the caecal contents of gilts exposed to low doses (LOAEL, NOAEL, and MABEL) of zearalenone. The experiment was performed on 60 clinically healthy gilts with average BW of 14.5 ± 2 kg, divided into three experimental groups and a control group. Group ZEN5 were orally administered ZEN at 5 μg/kg BW, group ZEN10—10 μg ZEN/kg BW and group ZEN15—15 µg ZEN/kg BW. Five gilts from every group were euthanized on analytical dates 1, 2, and 3. Caecal water samples for in vitro analysis were collected from the ileocaecal region. The genotoxicity of caecal water was noted, particularly after date 1 in groups ZEN10 and ZEN15 with a decreasing trend. Electrophoresis revealed the presence of numerous comets without tails in groups C and ZEN5 and fewer comets with clearly expressed tails in groups ZEN10 and ZEN15. The distribution of LLC-PK1 cells ranged from 15% to 20% in groups C and ZEN5, and from 30% to 60% in groups ZEN10 and ZEN15. The analysis of caecal water genotoxicity during exposure to very low doses of ZEN revealed the presence of a counter response and a compensatory effect in gilts.
