The metabolic and immunological indicators were determined in the blood of laying hens of ISA BROWN hybrid divided into three groups, the control group and two experimental groups. The administration of n-3 polyunsaturated fatty acids (PUFA) in the form of linseed (Group 1) and fish oil (Group 2) and α-tocopherol as antioxidant to laying hens resulted in a significant increase in concentrations of high density lipoproteins (HDL) cholesterol (P < 0.05), eicosapentaenoic (EPA), docosahexaenoic (DHA) and α-linolenic acids (AA) in blood in comparison to the control group. Significantly lower levels of cholesterol (CHOL) were determined in both experimental groups at the third sampling (P < 0.05) and arachidonic acid (AA) in the fish group (P < 0.01). The metabolic activity of phagocytes and polyclonal activation of lymphocytes showed no significant differences and remained within the physiological range. Oral administration of n-3 PUFA showed no significant increase of the immune response of experimental animals.

The aim of the present study was to describe the effect of digitonin on egg quality, cholesterol content in eggs, some parameters of serum lipid metabolism and blood picture of laying hens. The experiment was split into 3 groups (8 laying hens per group); group 1 was fed control feed mixture with 16.54% crude protein and 11.61&nbsp;MJ ME, group 2 received control feed mixture with 0.01% digitonin and supplement of digitonin in group 3 was 0.025%. Digitonin in the amount 0.025% significantly (P&le; 0.05) reduced egg weight from 65.07 g in control group to 61.44 g in group 3, white weight (41.21 g vs. 37.96 g), and egg cholesterol content (13.64 mg/g vs. 12.95 mg/g of yolk). Digitonin significantly (P &le; 0.05) increaced HDL cholesterol (0.43 mmol/l in control group to 0.59 mmol/l in group 3) and triglycerides from 13.47 mmol/l (control) to 16.90 mmol/l (group 3) in blood serum. Significantly (P&nbsp;&le; 0.05) lower number of erythrocytes and MCV value in group 3 were observed. &nbsp;

Summary The experience accumulated with low-intensity extracorporeal shock wave therapy (LI-ESWT) from international clinical trials has demonstrated its safety, efficacy and good tolerance in treatment of erectile dysfunction (ED). The aim of this retrospective study was to investigate the effect of LI-ESWT in patients with ED after bilateral nerve sparing radical surgery for prostate cancer. Twenty-seven patients underwent bilateral nerve sparing radical retropubic prostatectomy (BNSRRP) at the clinic of urology of the university hospital in Pleven between January 2016 and December 2016. Twenty-one of these patients had pre-operative preserved erectile function (EF), as reported according to the International Index of Erectile Function (IIEF-5). Postoperatively, these 21 patients experienced a mild (18-21 points) impairment of EF. In 10 patients (group 1), LI-ESWT was performed. The procedure was performed once a week for 6 weeks with a LI-ESWT (BTL 6000 SWT Topline) instrument. The reading was obtained with IIEF-5 on the third and sixth month after the end of therapy. The other 11 patients (group 2) were used as a control group and did not receive treatment. In 5 patients in group 1, a recovery of EF (> 21 points) as per IIEF-5 was recorded at the third month after treatment. In two patients, the same score was recorded at the sixth month. No improvement was seen in three men in group 1. In the controls (group 2), a spontaneous EF improvement in four patients at sixth month was registered. Despite the small number of patients and their short-term follow-up, our initial results indicate that LI-ESWT is effective, safe and well-tolerated. It could be an alternative for early penis rehabilitation in patients who have undergone BNSRRP.

We examined 66 women who were 22-40 weeks pregnant and their newborns. Of these, 15 women with moderate PE were in group 1, 22 women with severe PE were in group 2, and 55 women with uncomplicated pregnancy without hypertensive disorders were in the control group. Blood was taken from women when they were admitted to the clinic, and newborns ‘ blood was taken for 3-5 days of life. Free radical oxidation and antioxidant activity were evaluated by induced chemiluminescence. It was found that in patients with severe and moderate preeclampsia, the development of oxidative stress is accompanied by a weakening of antioxidant activity. In newborns born to mothers with preeclampsia, oxidative stress is accompanied by a compensatory increase in antioxidant activity.

Aim Posterior capsular opacification is treated using neodymium-doped yttrium aluminium garnet laser capsulotomy that leads to increased intraocular pressure. Here, we compare the effects of dorzolamide hydrochloride + timolol maleate versus brimonidine on intraocular pressure. We also investigate their side effects after neodymium-doped yttrium aluminium garnet laser capsulotomy. In these patients, there are no prior studies comparing the results of these two drugs. Materials Ninety patients with posterior capsule opacification contributed to the study. They received yttrium aluminium garnet laser capsulotomy. After yttrium aluminium garnet laser capsulotomy, they were randomized into three groups. Group 1 received dorzolamide hydrochloride + timolol maleate; Group 2 took brimonidine; and Group 3, the control group, took no drug. Group 1 took dorzolamide hydrochloride + timolol maleate eye drops 1 h before the procedure and on the third hour of the first day and two times per day between the second and the seventh days. Group 2 took brimonidine eye drops 1 h before the procedure and on the third hour of the first day, two times per day between the second and the seventh days. Results Brimonidine had a similar side effect profile to the fix combination. Intraocular pressure on the first ( p = 0.87) and third days ( p = 0.124) were similar in Group 1 (dorzolamide hydrochloride + timolol maleate), Group 2 (brimonidine) and the control group. The mean intraocular pressure value of the control group was significantly higher than Groups 1 and 2 because the anti-glaucomatous effects of the drugs become prominent on the seventh day ( p = 0.041). In Group 1 and Group 2, intraocular pressure was significantly lower than the control group on the seventh day ( p = 0.041). Stinging, itching, hyperemia and Tyndall rates were similar in Group 1, Group 2 and the control group. Watery eyes were less common in the brimonidine group than in the dorzolamide hydrochloride–timolol maleate and the control groups on the seventh day ( p = 0.02). Brimonidine also significantly lowered the chemosis rate on the third ( p = 0.04) and seventh ( p = 0.03) days. Conclusion We suggest that brimonidine and a combination of dorzolamide + timolol are similarly effective at reducing eye pressure for routine cases. In cases where intraocular pressure attacks might be at higher risk, using the dorzolamide + timolol combination would be more appropriate.

The aim of the study was to evaluate the influence of preventive activities involving the use of a coccidiostatic product containing Origanum vulgare and Citrus spp. extracts on the slaughter value of lambs from a confined management system. The study material was a group of 222 mother ewes and 276 lambs of the Polish Lowland breed. During the whole experiment the animals were kept in a confined management system, indoors, with uniform environmental conditions. On the basis of the parasitological analysis the flock was divided into three groups similar in both the intensity and the extensity of parasitic infections: Group 1: a control group, whose diet was not supplemented (74 mother ewes, 87 lambs); Group 2: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing the lambs were fed like the control group (73 mother ewes, 105 lambs); Group 3: diet supplemented with OILIS SD, a product with coccidiostatic effect, from the third month of pregnancy to lambing, the lambs receiving feed with OILIS SD starting from the 14th day of life (75 mother ewes, 84 lambs). Out of 276 lambs included in the experiment, 18 rams and 18 ewes representing all the observed groups were chosen for slaughter. The lambs were slaughtered around day 100 of their life (± 6 days). The observations showed that the animals from Group 3, in which the feed of both mother ewes and lambs was supplemented with a coccidiostatic product, were characterized by a higher slaughter weight: 30.80 kg, in comparison to 27.80 kg in Group 1 and 26.90 kg in Group 2, which has been confirmed as statistically significant (p ≤ 0.05). This corresponded to the achieved carcass weight. The highest average hot carcass weight (13.36 kg) was noted in Group 3, while the parameters for Group 1 (11.88 kg) and Group 2 (11.28 kg) were significantly lower (p ≤ 0.05). The conducted post-slaughter analysis clearly showed that the coccidiosis prevention measure consisting in a product containing the ether oils of Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) has a beneficial influence on the slaughter value of lambs, and results both in a higher carcass weight and the weights of specific cuts and tissues..

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

Effects of a dopamine-1 (DA-1) receptor agonist on systemic and intestinal oxygen delivery (D˙o 2)-uptake relationships were studied in anesthetized dogs during sequential hemorrhage. Control ( group 1) and experimental animals ( group 2) were treated similarly except for the addition of fenoldopam (1.0 μg · kg−1 · min−1) in group 2. Both groups had comparable systemic criticalD˙o 2(D˙o 2crit), but animals in group 2 had a higher gut D˙o 2crit(1.12 ± 1.13 vs. 0.80 ± 0.09 ml · kg−1 · min−1, P < 0.05). At the mucosal level, a clear biphasic delivery-uptake relationship was not observed in group 1; thus oxygen consumption by the mucosa may be supply dependent under physiological conditions. Group 2 demonstrated higher peak mucosal blood flow and lack of supply dependency at higher mucosalD˙o 2 levels. Fenoldopam resulted in a more conspicuous biphasic relationship at the mucosa and a rightward shift of overall splanchnic D˙o 2crit despite increased splanchnic blood flow. These findings suggest that DA-1 receptor stimulation results in increased gut perfusion heterogeneity and maldistribution of perfusion, resulting in increased susceptibility to ischemia.

Burnout is a reality in the teaching profession. Specifically, teaching staff usually have higher burnout rates. The present study aims to analyze the different burnout profiles and to verify if there were differences between burnout profiles in depressive symptomatology and in the self-esteem of the teachers at school. The total number of participants was 210 teachers from 30 to 65 years. The first scale was the Maslach burnout inventory, the second scale was the Self-Rating depression scale and the third scale was the Rosenberg Self-Esteem Scale. The latent class analysis identified three burnout profiles: the first group with a high level of emotional exhaustion, low personal accomplishment and depersonalization (high burnout); the second group with low emotional exhaustion, low depersonalization and high personal accomplishment (low burnout) and the third group with low depersonalization, low emotional exhaustion and low personal accomplishment (moderate burnout). The results revealed that there were differences in depressive symptomatology (group 1 obtained higher scores than group 2 and group 3) and self-esteem (group 2 obtained higher scores than group 1). The psychological balance and health of teachers depend on preventing the factors that have been associated with this syndrome.

Введение. Сосудистые осложнения сахарного диабета (СД) являются одной из ведущих причин повышения смертности пациентов трудоспособного возраста. Предполагается, что индуцированный гипергликемией окислительный стресс и нарушение антиоксидантной защиты играют роль в патологическом механизме повреждения сосудов, частично за счет влияния оксида азота (NО). Цель исследования: уточнение взаимосвязей в системах асимметричного диметиларгинина (АДМА) и NO у пациентов с цереброваскулярными заболеваниями (ЦВЗ) на фоне СД 2-го типа (СД-2). Материалы и методы. Обследованы 72 пациента с ЦВЗ со стенозирующим поражением внутренней сонной артерии вне острого периода: группу 1 составили 39 пациентов (18 мужчин и 21 женщина) с СД-2 в возрасте 65 [58; 72] лет; в группу 2 вошли 33 больных (15 мужчин и 18 женщин) без СД-2 в возрасте 66 [56; 74] лет. Контрольную группу составили 30 добровольцев (16 мужчин и 14 женщин) без проявлений церебральной ишемии и нарушений углеводного обмена, с нормальными значениями индекса массы тела, некурящие, в возрасте 62 [50; 66] лет. Проводилось клиническое обследование, нейро- и ангиовизуализационное исследование, спектр биохимических исследований крови, в том числе определение содержания АДМА и показателей системы NO. Результаты. В группе 1 содержание нитрата, нитрита и NO составило 62,1 [56; 68] мкмоль/л, 48,5 [26; 52] мкмоль/л и 13,6 [9; 23] мкмоль/л соответственно, что достоверно отличалось от значений этих показателей в группе 2 — 58,3 [45; 64] мкмоль/л, 39,6 [26,0; 42,3] мкмоль/л и 18,7 [16,1; 24,7] мкмоль/л соответственно. Отмечен также более высокий уровень AДМА в крови у пациентов с ЦВЗ в сочетании с СД-2 — 0,42 [0,21; 0,53] ммоль/л. Заключение. Обнаружена взаимосвязь между уровнями AДМА и NO при ЦВЗ на фоне СД-2. Это требует продолжения исследований биомаркеров повреждения сосудистой стенки для определения их места в патогенезе ишемических церебральных осложнений СД-2. Background. Vascular complications of diabetes mellitus (DM) are one of the leading causes of increased mortality in patients of employable age. Hyperglycemia-induced oxidative stress and impaired antioxidant protection have been suggested to play a role in the pathological mechanism of vascular damage, in part due to the effects of nitric oxide (NO). Objectives: clarification of relationships in the systems of asymmetric dimethylarginine (ADMA) and NO in patients with cerebrovascular diseases (CVD) and type 2 diabetes (DM-2). Patients/Methods. We examined 72 CVD patients with stenosing lesions of the internal carotid artery outside the acute period: group 1 consisted of 39 patients (18 men and 21 women; 65 [58; 72] years old) with DM-2; group 2 consisted of 33 patients (15 men and 18 women; 66 [56; 74] years old) without DM-2. The control group consisted of 30 volunteers (16 men and 14 women; 62 [50; 66] years old) without manifestations of cerebral ischemia and carbohydrate metabolism disorders, with normal body mass index, non-smokers. A clinical examination, neuro- and angio-imaging study, a spectrum of biochemical blood tests, including the concentration of asymmetric dimethylarginine (ADMA) and indicators of NO system were carried out. Results. In group 1, the content of nitrate, nitrite and NO was 62.1 [56; 68] μmol/l, 48.5 [26; 52] μmol/l and 13.6 [9; 23] μmol/l, respectively, that significantly differed from the content of these parameters in group 2 — 58.3 [45; 64] μmol/l, 39.6 [26.0; 42.3] μmol/l and 18.7 [16.1; 24.7] μmol/l, respectively. Noted also a higher blood level of ADMA in patients with CVD combined with DM-2 — 0.42 [0.21; 0.53] mmol/l. Conclusions. A relationship was found between ADMA and NO levels in CVD patients with DM-2. This requires further studies of biomarkers of vascular wall damage to determine their place in the pathogenesis of ischemic cerebral complications of DM-2.
