Oxidative stress and associated oxidative damage are mediators of vascular injury and inflammation in many cardiovascular diseases, including hypertension, atherosclerosis, ischemic heart disease, diabetes. Xanthine oxidoreductase is one of the enzymes producing free radicals in the cardiovascular system, and it can contribute to the increment of the oxidative stress and, consequently, blood pressure. The xanthine oxidase is a molybdoenzyme capable of catalyzing the oxidation of hypoxanthine and xanthine in the process of purine metabolism. Xanthine oxidase can exist in two interconvertible forms, either as xanthine dehydrogenase or xanthine oxidase. The aim of the paper was investigate the activity xanthine oxidoreductase in the plasma patients with age related cataract, with hypertensive, and with heart failure. Clinical and biochemical researches were carried out in 73 patients with age related cataract, mean age 72±7 years, divided into group with hypertensive (N=35), with heart failure (N=22) and group normotensive and without heart failure (N=16). Plasma xanthine oxidoreductase activity was determined spectrophotometrically by measuring the formation of uric acid from hypoxanthine at 293 nm. The concentration of triglycerides (TG), total cholesterol (TC), LDL-C, HDL-C in plasma were determined. Our findings show a significantly increased activity xanthine oxidoreductase in plasma hypertensive patients (XO 9.18±1.5 U/L) (p< 0.001) and patients with heart failure (XO 10.44±1.53U/L) (p< 0.001), compared with values plasma xanthine oxidoreductase activity in normotensive and patients without heart failure (XOD 6.02±1.4 U/L). Concentrations of plasma TG, TC and LDL-C were elevated in groups with hypertensive and with heart failure, and we to find significant differences with group normotensive and without heart failure values. Elevated activity of plasma xanthine oxidoreductase contribute to the increasåd oxidative stress and may play a role in accelerated atherosclerosis. 

Metformin is an anti-hyperglycemic agent used for the treatment of type 2 diabetes mellitus. Biguanides lower blood glucose levels primarily by decreasing the amount of glucose produced by the liver. Metformin also helps to lower blood glucose levels by making muscle tissue more sensitive to insulin so glucose can be absorbe. The purpose of the study was to establish the effect of metformin on insulin secretion in obese patients with newly diagnosed diabetes mellitus type 2. We included 40 patients with Type-2 Diabetes Mellitus, who were treated on Department for Internal Disease in Hospital King Milutin Laplje Selo. Patients included in the study were newly diagnosed with diabetes mellitus type 2, glycemia < 12 mmol/L, and hed the Body Mass Index >30 kg/m2. They were treated with metformin, 1000 mg/day. Insulin sensitivity was determined by HOMA IR, insulin secretion by HOMA, lipid status by spectrophotometry. After six months of treatment blood biochemistry tested again. BMI was also established. Metformin significantly lowered BMI (BMI before therapy 31.02 kg/m2, after treatment 28.7 kg/m2) (both p<0,001 vs baseline) waist circumference mean value 98±0.55 cm-93,12 cm. (p<0,001) During the therapy the glycaemia decreased from 11.7 mmol - 6,78 mmol/l, insulinemia mean value 20.141 mlU/l -13.691, HOMA IR elevated in all patients. Among the cholesterol fractions, most significant results were obtained in LDL cholesterol. Mean LDL cholesterol levels 4.51± 2.02 mmol/L. Mean cholesterol level 6.98±2.31 mmol/L. HDL levels -1.32 mmol/L. Serum triglycerides was (mean) 2.63±1.32mmol/L. After six months therapy Metformin produces beneficial changes in lipid states. Metformin may be the first therapeutic option in the diabetes mellitus type 2 with overweight or obesity. Metformin produces beneficial changes in glycemia control, and moderated in weight, lipids and insulinemia. 

Evaluation of population health condition is a basic mode of collecting health condition and health needs data of a population. Evaluation of population health condition is a base of contemporary health care and health service as well as health improvement and further health system development. In order to gain information on all (physical, psychological and social) health aspects, one has to go beyond health care system and consider objective health condition indicators gained by routine health statistics along with subjective information for creation an image of health condition, that is to say data collected from citizens themselves. This is significantly important when health condition data are sparse, as this is the case with health marginalized groups such as refugees and displaced persons. Value of data collected in this way is in the fact that they refer to determinants defining health, such as social-economical status, life style, education, employment, quality and availability of health care. The aims of this research is to establish how refugees, housed in refuge camps in the North Kosovo and Metohija, evaluate their health and what are the most common health problems of this population. The research was undertaken as a study of a standard representative sample of the adult refugees housed in the refuge camps in the North Kosovo and Metohija. It involved 109 surveyed people. The questionnaire, used for Health Examination in the Republic of Serbia adapted to local conditions, was utilized as a research instrument. The data were processed by descriptive statistics methods 2 and ÷ test was used in the means of data analyzing. More than a half of the surveyed (55.1%) answered that their health condition was good and very good. There is a great difference in health self-evaluating regarding age, marital status, education, the year when they arrived to current domicile. Less than two thirds (65.2%) of the surveyed in the refuge camps in North Kosovo and Metohija claimed that they suffer from some mentioned chronic illnesses. 

Formation of vascular access in elderly and diabetic patients is burdened with many difficulties. The aim of this study was to determine the factors that older people and patients with diabetes mellitus defined as the population risk for the formation of arteriovenous fistula for hemodialysis. The study was organized as a retrospective study, a subject of interest in people older than 65 years of age and diabetes, which in four years because of the need for further treatment performed arteriovenous fistula. Analyzed the demographic structure of the patient, type of anastomosis, the use of central-venous catheters for hemodialysis, arterial blood pressure and size of the lumen of blood vessels used for anastomosis, intraoperative measured. From the laboratory analysis determined the routine hematological and biochemical parameters. In relation to the positioning of arteriovenous fistula (p=0.033), the placement of catheters for hemodialysis (p=0.0009), preventive form of vascular access (p=0.04) and values of systolic (p=0.0001) and diastolic (p=0.0001) arterial blood pressure, achieved a statistically significant difference. Patients with diabetic nephropathy, compared to the population of elderly, have a significantly higher number of leukocytes (7.5±2.61 vs. 8.5±3.24, p=0.03), fibrinogen level (5.57±2.39 vs. 6.8±1.71, p=0.036), glycemia (5.35±1.24 vs. 7.1±2.28, p<0.0001), cholesterol (3.77±1 , 03 vs. 4.5±1.71, p=0.001), triglycerides (1.59 ±0.62 vs. 1.86±0.76, p=0.009) and LDL-cholesterol (2.13±0.76 vs. 2.42±2.04, p=0.02). Total proteins (64±9.98 vs. 62 ±7.4, p=0.027) and albumin (36±34 vs. 9.55±5.49, p=0.037) were significantly lower values in diabetics. Characteristics of older diabetics and is characterized as a risk population of patients for the creation of arterio-fistula were timely creation and position of arterio fistula, the need for placement of central-venous catheters for hemodialysis and arterial blood pressure.

Arrhythmogenic right ventricular dysplasia (ARVD) is a myocardial disease, often familial, that is characterised pathologically by fibrofatty replacement of the right ventricular myocardium, and clinically by ventricular arrhythmias of right ventricular origin which may lead to sudden death, mostly in young people and athletes. The term "dysplasia" was originally used to describe an entity that was considered to be the result of a developmental defect of the right ventricular myocardium.

Degenerative diseases are no inflammatory diseases intervertebrales discus, joints and ligaments vertebrae with subsequent changes in the bony spine structures. Degenerative diseases are very common and lumbar syndrome is most of them common. Because large disability that gives not only a medical but also social and economic problem. Starting of these facts here, work is set purpose,to the overall context of the diagnosis,differential diagnosis of degenerative lumbar sindrom. This is a complex problem that requires a great effort, expertise and modern diagnostic procedures in clinical rheumatology, which is outstanding problem in practice. We hove processed 55 patients with chronic low back pain and 20 patients with chronic low back pain and other etiology. With history, clinical examination, laboratory analysis, Rtg recordings,and other additional analysis (EMG,CT,MRI) that dodge tried to make the diagnosis and successful treatment.

Diagnosis of different pathohystological diseases of prostate in the most cases based on common benignant and malignant characteristics. The presence of periacinar cleftings (PC) is an additional criterion favouring prostatic adenocarcinoma. The aim of our work was to examine the presence of PC around glands in prostatic adenocarcinoma (PA), prostatic intraepithelial neoplasia (PIN) and benign hyperplasia of prostate (BHP) and to determinate specificity and sensitiveness for their presence in PA. We analysed biopsy material of Institute of pathology, Medical faculty Priština and Department of pathology and forensic medicine Clinical center of Kragujevac from begining of 2007. till the end of 2008. According to the presence and extent of PC, analysed on high power field (400x), glands were classified as: group 1 - glands without PC or with PC affecting ≤50% of gland circumference; group 2 - glands with PC affecting >50% gland circumference in <50% examined glands and group 3 - glands with PC affecting >50% gland circumference in ≥50% examined glands. By the analyse of our material we found PC around glands in PA, PIN and BHP: the most glands in PA were group 2 (34 or 48,6%) and group 3 (31 or 44,3%), in PIN group 1 (12 or 60%) and group 2 (8 or 40%), in BHP glands at all 100% cases were group 1. We found sensitiveness 92,9% and specificity 73,3% for glands with PC at prostatic adenocarcinoma, which indicate that periacinar cleftings represent a reliable criterion in diagnosis prostatic adenocarcinoma. 

The combination of aspirin and ticlopidine has been proven to reduce the frequency of haemorrhagic and vascular complications after coronary artery stenting, but also can cause serious hematological side effects. The purpose of this study was to evaluate the effect and interactions aspirin and ticlopidine on hematological variables. Thirty two Wistar rats were divided in four groups and they received intraperitoneal one of the following treatments for 4 days: group I - control, group II aspirin (50 mg/kg BM), group III - ticlopidine (125 mg/kg/day) and group IV - aspirin+ticlopidine combination (50 mg/kg/day+125 mg/kg/day). Hematological variables were determined at once after taking the sample of blood. Relationship between measured variables was determined by calculating linear correlation coefficient (r). The hematocrit, haemoglobin and red blood cell were significantly decreased in group treated with aspirin+ticlopidine combination compared to control (p< 0,05). Neutrophil and platelet count weren't significantly different in treated groups, but were slightly decreased in groups treated with ticlopidine and aspirin+ticlopidine combination. Between hematocrit and platelet count in control group of rats was noticed negative and medium correlation (r=-0,41), in groups treated with ticlopidine and aspirin+ticlopidine combination positive and medium correlation (r=0,52; r=0,69). Based on obtained results it can be observed significant decreased hematocrit, haemoglobin and red blood cell in group treated with aspirin+ticlopidine combination. The negative correlation between hematocrit and platelet count in control group becomes positive after the treatment with ticlopidine alone and aspirin+ticlopidine combination.

Biological equality assessments are carried out by means of: a) comparative pharmacokinetic study; b) comparative pharmacodynamic study; c) controlled comparative clinical experimentation; d) comparative in vitro assay (dissolution test). The first method mentioned, i.e. determining the concentration of a drug in the blood of healthy volunteers, is the most accurate and most frequently employed. In this paper, a study conducted on healthy volunteers that displays the possibility of evaluating biological equality using pharmacodynamic variable data, giving the example of such assay of retard tablets of verapamil produced by two different companies, is presented. Taking into account the effects of this drug, biological equivalence was proved by comparing pharmacodynamic variables such as PR interval, systolic and diastolic blood pressure and heart rate.

Background: In hernia inguinal regions that are usually on the front wall of the belly may appear epigastric, umbilical and postoperative (incision-ventrale) hernia. Incision (postoperative-ventral) hernia is the kind of hernia that occurs in the area before surgical incision made through the entire thickness of the abdominal wall. Purpose: The aim of this paper is to indicate the frequency incision, epigastric and umbilical hernia, and the validity of some methods used in surgical treatment. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica. This prospective study we included 107 (3.43%) patients with hernia abdominal front wall, which were operated in the Surgical Clinic from 2003- 2009th year. Results and discussion: the anterior abdominal wall hernia, are recorded in 48 (44.86%) male patients and in 59 (55.14%) female patients. Age is of great influence on the frequency of anterior abdominal wall hernia, because we have the largest number of hernia 45 (43.14%) recorded in patients older than 61 years. Free hernia we found in 68 (63.55%) and hernia incarcerate of 39 (36.45%) patients. Incision (postoperative) we found a hernia in 44 (41.12%), umbilical in 36 (33.65%) and epigastric of 27 (25.23%) patients. Postoperative hernia is most often occurring after longitudinal laparotomia. We have them registered in 19 (43.18%) patients with infraumbilical, in 10 (22.72%) with supraumbilical, in five (11.36%) with subcostal, with four (9.09%) with transrectal, at two (4.55%) with pararectal laparotomia, in two (4,55%) patients after lumbotomia made with two (4,55%) after Phanensthil incision. The treatment of the anterior abdominal wall hernia in 72 (67.21%) patients, we used prolen net, while in 35 (32.79%) patients made plastic abdominal wall. Drainage was used in 62 (57.94%) operated patients. In 78 (72.90%) patients applied the prophylactic dose of antibiotics, while in 29 (27.10%) patients applied therapeutic dose. The length of treatment of patients who applied prophylactic dose of antibiotics was 2.48 days and length of treatment of patients with therapeutic dose applied was 4.82 days. Prospective studies of patients in the postoperative complications are recorded in four (3.74%) patients. We had wound infection in two (1.87%) and recidive hernia in two (1.87%) patients. Conclusion: This surgical method, when it comes to herniotomia, a direct comparison with the number of postoperative recurrence. Implantation of mesh has found its place and it is a revelation in the resolution of abdominal wall hernia.
