Oxidative stress plays an important role in development of ulcer lessions of the rats exposed to indomethacin induced stress. It has been suggested that endogenous opioids releassed during the stress may attenuate gastric ulcer lesions. The aim of this study was to investigate effects of morpine on development of ulcer lessions, pathohistological alterations and antioxidative status in stomach of the rats exposed to indomethacin induced stress. Research was performed on adult, male Wistar rats weighting 200-230 g. Indomethacin stress was induced by intragastric administration of indomethacin at a dose of 20 mg/kg b.w. 6 hours before sacrificing. Morphine was applied intraperitoneally, in the doses of 10 mg/kg b.w. 15 minutes before indomethacin induced stress. The size of lesions in the form of petechiae and erosion, is expressed as the total surface of changes (mm2), i.e. ulcer index (UI). The pathohistological samples were analyzed by Leica DML S2 light microscope, and specific changes were photodocumented with Canon Power Shot S70 digital camera. In the homogenate of the stomach, the activity of catalase (CAT), glutathione peroxidase (GSHPx), glutathione reductase (GR) and xanthine oxidase (XOD) were measured, as well as the reduced glutathione content (GSH) and the lipid peroxidation intensity (Lpx). Morphine significantly reduced the ulcer index (UI) in animals exposed to indomethacin stress and the presence of large amounts of mucus in the stomach mucosal was established histopathologically. The use of morphine in the pretreatmant of indomethacin induced stress statistically significantly reduced the activity of all enzymes in the stomach compared to the control group, and this activity of catalase (CAT), glutathione peroxidase (GSHPx) and glutathione reductase (GR ), xanthine oxidase (XOD),as well as the lipid peroxidation intensity (Lpx), while the reduced glutathione content remained unchanged. Gastroprotective morphine activity in animals exposed to indomethacin induced stress is most likely a consequence of the strengthening of cytoprotective mechanisms rather than antioxidant action.

Quality of sleep is one of the prerequisites of health and life and work performance. During the anonymous testing by applying Pittsburgh scale, it was analyzed quality of sleep of the students of the University of Novi Sad. A total of 576 people. Results show that the quality of sleep is the best with the students of the Faculty of Sport. Students of the Faculty of Medicine have the shortest sleep, but quality of sleep is rated good. The duration of sleep is the longest with the students of the Faculty of Philosophy, and the quality is lower than in the other study groups.

Introduction: Direct and indirect pulp capping is a therapeutic procedure to preserve the tooth's vitality. The aim was to scan electron and polarization microscopy: analyze changes in cellular and extracellular components of dental pulp after direct and indirect overlay with glass-ionomer cement (GIC), determine the appearance of the dentine surface after direct and indirect pulping overlap with GIC and forms a proposal for a clinical application of preparations if it provides good and effective dentingenesis. Methods: The experiment was performed on experimental animals (domestic swine). For this research, alkaline cement was used ALFAGAL* bejz. On the teeth of the experimental group, preparations of the V class were made from the vestibular side. Twenty-two teeth were made indirectly, and twenty –two teeth directly covered with pulp. After completion of the preparation, dentin is directly covered with glass-ionomer cement (GIC) Alfagal* bejz. Through the ALFAGAL material for definitively closing cavities (amalgam) is laid. On the teeth where the perforation of the pulp chamber was made, ALFAGAL bejz was loaded directly into the pulp chamber, and through this the cavity was definitely sealed with GIC FUJI IX (GC Japan). Suitably prepared teeth and pulp were observed by SEM and a polarization microscope. Results: By observing and analyzing the obtained results, on a polarization and scanning electron microscope compared to the control group, results were obtained which can have a significant clinical implication in the biological treatment of the pulp. Alfagalbejz is directly applied in the pulp chamber: the boundary between newly developed reparative dentine is detected in the normal dentine structure, amorphous dentine, reproduction of connective tissue cells without pro inflammatory reactions and initial dedifferentiation in odontoblast, young blood vessels and cells (fibrocytes, histiocytes and fibroblasts) are observed. Indirectly applied Alfagal* bejz indicates the presence of different maturation stages of dentin, dentinal canals are clearly visible with a normal dentin structure, zero amorphous dentine and immature dentine structure are observed as well. The presence of an amorphous calcite of the dentine structure indicates the initial creation of a solid tissue barrier, which is the goal of the experiment. Conclusion: The results obtained by experimental research suggest ALFAGAL bejz as a good material for the direct and indirect overlap of the pulp.

Introduction: The presence of malignant altered axillary lymph nodes, and their timely detection is crucial for staging and prognosis of breast cancer. Echotomographic examinations are widely used technique, and represents one of the first tests of diagnostic modalities. Classic B mode, Doppler sonography, and MicroPure testing technique, allow a comprehensive assessment of the detailed morphology and internal structure of the nodes (number, location, size, shape, borders, echogenicity, edema of the surrounding soft-tissue, the presence of microcalcifications), and determination of their nature. Objective:The aim is to determine the role of echotomographic review the morphology, determining the nature and setting guidelines for diagnostic testing algorithm for malignant altered axillary lymph nodes. Materials and methods: This cross-sectional study included 212 echotomographic tested axillary lymph nodes in the Department of Radiological Diagnostics KBC "Dr Dragisa Mišović-Dedinje" in Belgrade, in the period from February 2016.do March 2017. All patients were examined in the supine position with arms in abduction, and external rotation. The following parameters: shape, size, and homogeneity of the echo-structure, edge, an auxiliary structures such as intranodal necrosis, edema and peripheral vascularization, as well as the presence of microcalcifications, using classical B mode, Doppler sonography and MicroPure technique. For all examinations we used Toshiba device, Aplio XG, 10MHz linear transducer. Results: Of a total of 212 tested nodule, histopathology was also verified 44 malignantly changed (21%), 4 of which the primary (9%) in a patient with Hodgkin's lymphoma, and secondary 40 (91%) in patients with breast cancer. Other nodes 168 (79%) were normal-reactive. The best performance in the echotomographic examinations are the criteria of: the shape (longitudinal cross-ratio <2) with a sensitivity of 86.9%, presence of microcalcifications with sensitivity of 83,7%, hilus (not clearly defined, and hypoechogenic) with sensitivity of 81.8%, the size (transverse diameter greater than 8mm), with a sensitivity of 79.2%, as well as echogenicity (hypo to anechogenic) with sensitivity of 73.1%. Conclusion: Echotomographic review is a useful imaging modality in evaluating the morphology and nature of axillary lymph nodes, but none echotomographic criterion in itself is not enough reliable in evaluating malignancy. Meticulousness when reviewing and examining all the criteria and modalities (B mode, Doppler, MicroPure) remain imperative in the diagnostic algorithm of tests axillary lymph nodes.

Correlation of fillings on the tooth and changes in the tissues having direct contact with the tooth aroused keen interest amongst many professionals. Irregularly shaped fillings can damage the periodontal tissues. The primary indicator of the validity of the dental work is its ability to ensure the preservation of normal physiological status of the tissue, primarily gingival, alveolus and periodontum. The main purpose of this paper is to make histological assessments of the tissue of the interdental region before and after correction of irregular filling in experimental animals. The research was conseived as a histiological study with experimental animals ( rabbits). The tested teeth were divided into two groups: a) the experimental group consisted of teeth with irregular fills, and b)the control group consisted of teeth with regular fillings and healthy teeth. The experiment carried out under general anesthesia. The experiment was being monitored over 12-month period. Having been expired the first part of the experiment , after 6-month period, in experimental animals, it was carried out the second part of the one consisting of the correction of irregular fillings. The second part of thhe experiment was closely monitored a month, three and six months after the correction of irregular filings. After sacrificing the animals, tissue was prepared for histological analysis. Histological analysis showed changes in the periodontal tissues prior to correction of irregular fillings and significant improvementof the tissue of the interdental region after correction of the same ones. The pathological changes occuring in the periodontal tissues are not irreversible since after correction of irregular filligs are being lost mainly.

Introduction: A self-assessment health condition provides a general approach to creating a picture of the health status of the population. Aim: The aim of the paper is to show the connection between different categories of self-assessed health with socio-demographic characteristics, risk factors and with the presence of one or more chronic non-communicable disease of adults in Serbian communities in Kosovo and Metohia. Method: The research was carried out as a cross section study. As an instrument for data collection, the questionnaire was applied in the 2013 Survey of the Health of the Population of Serbia (excluding Kosovo and Metohija), which is in line with the European Health Research Questionnaire. For the purposes of our research, the following variables were used; gender, age, education, working status, marital status, the presence of chronic non-communicable diseases, smoking, alcohol use and physical activity. Results: A total of 1067 respondents (51.3% of women) responded, with an average age of 42.2 (± 16.0) years. Most respondents in the survey found that they feel very good or good, a quarter of the middle (not bad or good), while their condition was poor or very poor assessed by just under 5% of respondents. Among the respondents who rated their health condition as poor or very poor, there were significantly more female respondents, middle age and 65 years of age. Also, people with primary and secondary education, economically inactive, and who are inclined to the sedentary way of life, have a poor picture of their health. The frequency of people who assess their health status as bad or very bad is the highest among respondents with two or more chronic diseases. Conclusion: Different categories of self-assessment health show a tendency to connect with different individual characteristics of adult respondents. Our results can help in creating a strategy of action and building preventive programs in a defined area.

Introduction. Radius fracture at typical site - fractura radii loco typico, is one of the most common fractures (more than 10% of all fractures). It is frequent in the fall on the palm of the hand. It happens at all ages. Objective. To examine the efficacy of electromagnetotherapy in the treatment of patients with radius fracture at typical site in order to reduce pain, swelling and increased mobility of injured tissue and reduce the possibility of complications. Material and methods. The study includes 100 patients with radius fracture at the typical site of which 55 women and 45 men, aged 20 to 70 years. The study included patients undergoing bone trauma treated conservatively by plaster immobilization, immediately after orthopedic treatment patients were treated with lowfrequency pulsed electrical magnetic fields produced by the machine MAGNEMED MT - 91 results. Pain in the wrist after physiotherapy treatment static isometric contractions and after the application of electromagnetic therapy was significantly more intense in the control group. Swelling in the wrist were significantly reduced in patients treated with electromagnetic fields. In all patients, after 20 applied electromagnetic field therapy achieved a significant increase in flexor and extensor muscle strength. Electromagnetotherapy is important in the prevention of complex regional pain syndrome.

INTRODUCTION: Urinary tract infections are one of the most common infections in young children. Febrile conditions in young children, without specific clinical signs and symptoms are often the result of ITU. Usually later diagnosed and treated. The most common cause of ITU is Escherichia coli. The main problem in the treatment of ITU is increasing resistance to antibiotics. AIM: To point out all the frequent resistance to antibiotics and to compare the frequency of the experimental periods. MATERIAL AND METHODS: We performed a retrospective study in the period of 2010-2015. Urine samples for microbiological examination were taken before switching on antibiotics. Statistical analysis was performed in SPSS software. RESULTS: In our study found 183 patients with a diagnosis of ITU. Somewhat higher percentage were present, patients were female. The highest resistance to ampicillin was found in our results in the time period is 5 years, found a drop resistance Amoxicilin and Amoksiklav. DISCUSSION: Our results showed a strong similarity with the works on the same theme, which is Escherichia coli, the most common cause of ITU in young children. ITU are represented within the female population. CONCLUSION: It is important to continuously monitor the representation of urinary tract infections as well as their sensitivity to antimicrobial drugs, because of the increasing presence of the bacterial resistance to existing antibiotics.

Introduction: During the course and development of diverse cardiological diseases different central nervous system complications may develop. These are most frequently related to the nature of the cardiovascular entity itself. Aim: To evaluate the association between atherogenesis factors and border zones strokes within the cerebral medial artery vascularization territories. Methods: In total 30 patients were enrolled in the study. Stroke diagnosis was based according to clinical and neurological examination and brain CT findings. The study analyzed risk factors correspondingly to World Health Organization criteria. Results: In majority of patients (18; 60%) arterial hypertension was diagnosed. Additionally, following condition and risk factors were identified: cardiological diseases (17; 23.3%), cigarette smoking (13, 43.3%), hypercholeterolaemia (9; 30%) and diabetes (7; 23.3%). In the group with cardiological diseases most frequent was myocardial infarction (9; 56.2%), AV block II and III (5, 29.4%), atrial fibrillation with slow ventricular response (3; 17.6%). Conclusion: Results of the study point to conclusion that myocardial infarction, AV block II and III, atrial fibrillation with slow ventricular response, iatrogenic hypertension and traditional risk factors for atherogenesis significantly influences presentation of the border zone strokes within the cerebral medial artery vascularization territories.

Introduction: One of the basic tasks of the orthodontist is to establish a proper dental array, to provide a favorable mastication function and an adequate appearance of the maxillofacial complex.Aim: The aim of this paper was to determine whether the values obtained from Moyers' tablets within the 75% probability correspond to the values the width of the side segment measured on our population. Subjects and method: The study included 60 people with a constant dentition of age from 15 to 18 years (30 men and 30 women). Results: The total tooth width of the side segment in the upper and lower jaw obtained from Moyers's analysis is significantly higher than Our findings, regardless of gender, with an average of about 1mm. Conclusion: We have defined the new regression equations for calculating the size of the C-P2 segment for the upper and lower jaws especially for men and especially for females.

The studies based on photography and communication of visual information via smart mobile phones have been especially popular. This paper represents a review of the studies about teledentistry published in the last several of years, discuss them and puts forward the recommendations for future research.

Hypoglycemia is defined asplasma glucose level sufficiently low to result in neurological damage. In the new-born age, the incidence of hypoglycemia ranges from 0.4-11.4%. Etiologically, low levels of plasma glucose can result from the hormonal or metabolic disorders; high doses of insulin, drug poisoning, liver disease or systemic disorders. The most common cause of severe and permanent hypoglycemia in the neonatal age group is congenital hyperinsulinism - the result of pancreatic cells hyperplasia and/or adenoma. Between two and five years of age, the most common form of hypoglycemic state is ketotic hypoglycemia of childhood, caused by limited amount of substrate. Diagnostic criteria include biochemical confirmation of low of glucose and/or high insulin levels, blood hormone testing (epinephrine, cortisol, growth hormone, glucagon levels), as well as metabolic screeningfor gluconeogenesis, glycogenolysis, and lipolysis disorders and disarrangements of fatty acid oxidation. Therapy is directed towards the substrate supplementation and the application of medications and fuels aiming atrapid attainment of normoglycemia (fruit juices, parenterally applied glucose and dextrose, glucagone, corticosteroid therapy); diazoxide and somatostatin therapy is indicated for patients with hyperinsulinemia.

Newly synthetized derivative of bile acid, sodium salt of 3α, 7α-dihydroxy-12-oxo 5β cholanic acid (monoketocholanate) expressed a good characteristic as intranasal transport enhancer of xenobiotics.The aim of our sudy was to explore if it has an influence on bile metabolism and to measure its concentration in blood and bile after intravenous and intranasal administration. The experiment was performed in vivo on adult male Wistar rats. The determination of monoketocholanate (MKCh) in rats blood and bile, was carried out by high-performance liquid chromatography (HPLC), on an HP ODS2 column, using methanol/acetonitrile/acetate buffer as mobile phase. Absorbances were measured at 210 nm.Blood samples were taken from the prepared right axillary artery in 0, 1, 5, 10, 20, 30, 60, 90, 120 and 180 minutes from the beginning of the experiment. Bile was collected in a half an hour intervals,during the three hour period. The results showed that MKCh changed the amount of excreted bile depending on the way of application. Intranasal application increased the bile volume and the MKCh concentration, both in blood and bile compared to the intravenous application (p<0.05). Distributionm of MKCh through animal organism depends on the way of application of the substance, which probably determines its caracterisation as the transport promotor of applied xenobiotics. HPLC has proved as aa relatively simple, fast and effective method for the determination of synthetic bile acid,MKCh in these biological materials.
