Activity of erytrocyte glutationperoxidase (GP), glutationreductase (GR), glutationtransferase (GT), glucose-6-phosphatdehydrogenase (G6PDH), catalase and superoxiddysmutase (SOD), and also, the level of malonic dialdehyde (MDA) and total antioxidant activity of blood serum were studied in patients with different types of multiple sclerosis. Investigation of peripherical blood was carried out on first day of treatment and after standard therapy of copaxone. All MS patients had high level of MDA and activity of GP in erythrocytes in comparison with a control group. Other antioxidant enzymes of erythrocytes and total antioxidant activity of blood serum exhibited weak positive dynamics in patients with a relapsing remittance of multiple sclerosis (RRMS). Decrease of activity of antioxidant system in patients with secondary progression multiple sclerosis (SPMS) was more pronounced and remained unchanged after the treatment. This is consistent with the more severe clinical course of thise disease.

Introduction. The overwhelming number of publications contains only data on the content of individual antioxidants, but not on the overall antioxidant activity of the blood in patients with vibration disease.The aim of the study was to determine the total antioxidant activity of blood serum in patients with vibration disease.Materials and methods. Th e main group consisted of 30 people diagnosed with “Vibration disease” of 1 degree (n=21) and 2 degrees (n=9). Th e control group consisted of 30 clinically healthy men, comparable in age with the main group (p=0.66). Th e total activity of antioxidant systems of blood plasma was evaluated photometrically using the test system “Total antioxidant status-Novo” (“Vector-best”, Russia).Results. The indicator of the total antioxidant status (TAS) was 1,038±0.232 mmol/l in the examined main group, against 1,456±0.225 mmol/l in the examined control group (p<0.000001). Th e coefficient of variation (CV) in patients with vibration disease was 22.35%, 1.45 times higher than in the control group (15.45%). In the main group there was a positive correlation between age and TAS (R=0.525), in the control group there was no such relationship (R=0.095). Th e degree of decrease depended on the severity of vibration disease.Conclusions. 1. The development of vibration disease is accompanied by a decrease in the antioxidant status of blood serum. 2. Th e degree of decrease in the antioxidant status of blood serum correlates with the severity of vibration disease. 3. Reduction of TAS can serve as a pathogenetic justification of the need to include drugs and/or biologically active additives with antioxidant activity in therapy

The state of the blood antioxidant system in the patients presenting with acromegaly. The objective of the present study was to evaluate the total antioxidant activity (TAA) of blood plasma, the levels of non-protein thiols and 2-thyobarbituric acid-active products (TBA-AP), superoxide dismutase (SOD) and catalase (CAT) activities as well as ceruloplasmin (CP) level in the patients presenting with acromegaly. It was shown that plasma TAA and SOD activity in this patients was on the average 20 and 30% lower respectively than in the control subjects. At the same time, the TBA-AP and CP levels increased by 50 and 40% respectively. These data suggest the development of oxidative stress in the acromegalic patients.

This study was conducted to evaluate the effect of adding different levels of rocket salad seeds powder to the diet on seminal plasma traits of roosters subjected to oxidative stress induced by hydrogen peroxide. A total of 60 Hy – line laying breeder roosters 57 weeks old were used in this study. Roosters were randomly distributed into 5 treatments with 3 replicates each. Each replicate constituted of 4 roosters (12 roosters for each treatment). Experimental treatments were as following: T1: Males fed control diet and normal water, T2: Males fed diet supplemented with 3 gm rocket salad powder / kg of diet + 0.25 ml hydrogen peroxide (0.5%) / litter of water, T3: Males fed diet supplemented with 3 gm rocket salad powder / kg of diet + 0.5 ml hydrogen peroxide (0.5%) / litter of water, T4: Males fed diet supplemented with 3 gm rocket salad powder / kg of diet + 1 ml hydrogen peroxide (0.5%) / litter of water, and T5: Males fed control diet and drink tap water supplemented with 1 ml hydrogen peroxide (0.5%) / litter of water. Males were treated with hydrogen peroxide (6%) and rocket salad for 12 weeks starting from 59 week of male ages. Results revealed that treated the roosters with hydrogen peroxide without adding rocket salad powder to the diet of these roosters (T5) resulted in highly significant (p< 0.01) decrease as regards concentrations of phospholipids, cholesterol, glutathione, the activity of superoxide desmutase and catalase, and total antioxidant activity in seminal plasma and highly significant (p< 0.01) increase concerning concentrations of tyrosine and malondialdehyde as compared with control group (T1) and rocket salad powder treatments (T2, T3, T4) after 12 weeks of experiment. However, supplementing diet of roosters with rocket salad powder (T2, T3, T4) resulted in highly significant (p< 0.01) increase with relation to concentrations of phospholipids, cholesterol, glutathione, the activity of superoxide desmutase and catalase, and total antioxidant activity in seminal plasma and highly significant (p< 0.01) decrease respecting concentrations of tyrosine and malondialdehyde as compared with (T5) In conclusion adding rocket salad powder to the diet of roosters had important role in limiting the negative effect of oxidative stress induced by hydrogen peroxide on seminal plasma quality of roosters. Therefore, dietary supplementation with rocket salad powder could be used as one of important tools for improving semen quality of roosters.

Hyperhomocysteinemia plays a crucial role in the pathogenesis of many diseases of the central nervous system (CNS). The nervous system is particularly sensitive to high homocysteine (Hcy) level mainly due to its prooxidative and cytotoxic effects. Cladribine, a drug recently registered for the treatment of multiple sclerosis (MS), possesses additionally neuroprotective effects which are independent of its peripheral immunosuppressant action. Accumulating evidence suggests that oxidative stress and homocysteine thiolactone-mediated protein homocysteinylation play a causal role in MS. Both of these processes may be attenuated by paraoxonase 1 (PON1). Therefore, in the present study, we aimed to examine whether the beneficial effects of the drug in MS patients with a secondary progressive (SP) clinical course, treated with cladribine subcutaneously (s.c.), may be related to its ability to modify serum PON1 activity, Hcy concentration, and protein homocysteinylation, as well as to correct total antioxidant status. A total of 118 subjects were enrolled into the study: (1) patients with a SP type of MS, SP-MS (n=40); (2) patients with a relapsing-remitting (RR) type of MS, RR-MS (n=30); and (3) healthy people (n=48). Patients with SP-MS were treated with cladribine. The drug was given in SP-SM patients s.c. six times every 6 weeks up to a total mean cumulative dose of 1.8 mg/kg. PON1 activity was assessed spectrophotometrically. The level of Hcy, homocysteine thiolactone (HTL) attached to plasma proteins (N-Hcy-protein), and antibodies against homocysteinylated proteins was assessed with an enzyme immunoassay. The total antioxidant activity of the serum was assessed with the ferric-reducing activity of plasma (FRAP) method. Basically, there was no difference in PON1 activity between untreated SP-MS, RR-MS, and control subjects. Serum Hcy was significantly higher in RR-MS patients (p<0.001) and in SP-MS patients (p<0.01) compared to the control group. The N-Hcy protein level was higher in RR-MS patients (p<0.05) in comparison to the control group. Moreover, the elevated level of antibodies against homocysteinylated proteins was observed in the serum of patients with SP-MS. The total antioxidant capacity of serum was lower in MS patients vs. the control group (p<0.001). After cladribine treatment, the activity of PON1 did not change in SP-MS patients, whereas cladribine treatment decreased the level of total Hcy (p<0.05). Treatment with cladribine increased the total serum antioxidant activity in SP-MS patients (p<0.01). The Expanded Disability Status Scale (EDSS) score did not change in SP-MS patients. Cladribine treatment in the SP-MS group attenuates hyperhomocysteinemia-induced protein homocysteinylation (n.s.). It also stabilises the neurological condition of SP-MS patients. The stabilisation of a neurological condition observed in SP-MS patients after cladribine treatment may be partially related to its ability to reduce elevated Hcy level and to improve serum antioxidant potential.

The work is devoted to the research of the condition of the main components of the antioxidant system at the terms of the closed cranial cerebral trauma and at its pharmaceutical correction of Cerebrogermum.  It is determined that in case of using of Cerebrogermum the activity of superoxiddismutasa is rised in the blood serum in average on 35 % concerning the significations of the control group (the closed cranial cerebral trauma without treatment), on 72 hour of experiment the activity of this are fixed in the groups of both intact and reviewer rats. It does not also yield to reviewer preparation the ability of Cerebrogermum to resist to oxidizing stress because of the activity of catalasa. In relation to the estimation of antioxidant activity it considerably outweighs sizes for rats under influence of Cerebrogermum ( in average on 65 %) which are registered in the control group. The received in the experiment data give the basis to assert that the potential cerebral protector owns the exactly ability to resist to oxidative stress that is formed on a background of the mechanical damage of cerebrum.

Aim. To study the effect of the Leu-Ile-Lys (leucine-isoleucine-lysine) tripeptide on the course of experimental urate nephrolithiasis. Methods. The experiment was carried out on 23 male Wistar rats weighing 200220 grams that were divided into a control (n=8, modeling of urate nephrolithiasis) and an experimental (n=15, modeling of urate nephrolithiasis + administration of Leu-Ile-Lys tripeptide) groups. The tripeptide was administered intragastrically through a tube at a dose of 11.5 mg/kg. Daily urine was collected on a weekly basis, and the activity of lactate dehydrogenase and gamma-glutamyl transpeptidase was determined. After three weeks of the experiment, the animals were euthanized, and kidneys were removed to determine the parameters of free radical oxidation [concentration of thiobarbituric acid reactive substances (TARS), total pro-oxidant and total antioxidant activity, the activities of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPX)] and conduct a morphological study in which the number and area of calculi and the condition of the renal tissues were determined. Statistical data processing was performed using the Statistica 12.0 software. We used the MannWhitney U test, the Wilcoxon signed rank test. The results are presented as median with the 25th and 75th percentiles. The differences were considered significant at p 0.05. Results. In the kidneys of the rats of the experimental group, the number of deposits decreased twofold, as compared with the control group (1.60.2 and 3.20.4, respectively, p=0.001). Lactate dehydrogenase activity in the urine of rats increased from 0.10 (0.06; 0.21) units/mg of creatinine per day initially to 0.75 (0.44; 1.07) units/mg creatinine per day on day 21 (p=0.012) in the control group, and from 0.10 (0.06; 0.12) units/mg creatinine per day to 0.45 (0.34; 0.71) units/mg creatinine per day on 21st day (p=0.003) in the experimental group. The concentration of thiobarbituric acid reactive substances in the experimental group was 1.2 times lower than that of the control group: 4.2 (3.9; 4.6) mol and 5.1 (4.7; 5.5) mol, respectively (p 0.001). In addition, in the kidneys of the rats of the experimental group, the total antioxidant activity was 1.3 times higher than in control: 70.4 (65.4; 74.1)% and 53.8 (33.3; 62.2)% respectively (p 0.001). Superoxide dismutase activity in the experimental group was 1.5 times higher than in the control group: 12.4 (11.0; 13.2)% against 8.1 (6.4; 13.1)% (p=0.016). Catalase activity in the experimental group was 1.2 times higher than in the control group: 31.1 (26.4; 36.1)% against 25.1 (20.3; 27.1)% (p=0.005). Conclusion. The Leu-Ile-Lys tripeptide has a litholytic effect, manifested in a statistically significant decrease in the activity of oxidative stress markers (p 0,001) and a twofold decrease in the average amount of uric acid kidney stones (p 0,001).
