Health of soft oral tissue and periodontium in biggest measure depends as well of oral hygiene. It exists the positive correlation between oral hygiena and periodontal condition. Many systemic disease, as blood disease, change reactivity of organism and also peridontium, and directly take influence at course and difficulty of periodontitis.

In this review paper, metabolism of halogen derivatives of hydrocarbons (chloroform, polychlorinated biphenyls, freons) is shown. They are metabolized similar by mixed function oxidases (reductive or oxidative pathways). Their metabolites are toxic.

Acute organophosphate (ÎÐ) poisoning is an important cause of morbidity and mortality in children especially in the developing countries. Published studies work have been reported on acute childhood poisoning has focused mainly on the epidemiological trends, with little information about alteration in electrolitic and acid-base equilibrium and other disturbance and on the management of the poisoned children. Hypovolaemia, electrolyte derangements and acidosis are major predisposing factors for development of complications. Metabolic acidosis is one of the major causes of death in patients poisoned with OPC acutely. We suggest that children's with acute OPC poisoning should be screened for electrolyte and metabolic acidosis with blood gas analysis.

Cephalosporins are bactericidal antibiotics that are active against a wide variety of Gram(+) and Gram(-) aerobic bacteria, along with a few anaerobic species. Adverse effects of cephalosporins are uncommon and reversible. Cefalotin and cefaloridine exhibit a nephrotoxic effect and might cause renal tubule necrosis. No data about the nephrotoxicity of cefotaxime and ceftriaxone has been presented in literature so far. When cephalosporins are applied via intramuscular injection a local reaction is possible, whereas with IV administration thrombophlebitis develops in about 5% of all cases. Hypersensitivity reactions, as well as some hematological disorders (thrombocytosis, leukopenia, neutropenia) might also occur. Cephalosporins were found to sometimes cause an augmentation of transaminase (AST, ALT), alkaline phosphatase, and, less frequently, bilirubin levels, too. The goal of this study was to evaluate the creatinine values in the serum of patients hospitalised in Kosovska Mitrovica Health Centre. The values were determined before, within and after 7 days of cephalosporin administration (cefotaxime 2x1000mg IM; ceftriaxone 2x1000mg IV). Data concerning certain hematological and biochemical variables will be presented as well. Creatinine levels were measured by the Jaffe reaction method. Both cefotaxime and ceftriaxone yielded a statistically significant increase of the serum creatinine values. As these cephalosporins do not show a nephrotoxic effect, the increase can be explained by the interference of sodium picramate, a byproduct of the Jaffe reaction which is produced regardless of whether the process is manual or automated.

Allergic disease are actual pathologic condition in medicine. From this diseases can get ill people of any age, both sex, and the number of patients with allergic diseases rapidly increase in countries of progressive world. This disease are wide - spread, with tendency of increase, and they can have fatal result in extreme cases. Because of high prevalence of morbidity and complications they have, allergic diseases are health problem. According to World allergic organization, more than 40 % of population in world will be atopic. In our environment this diseases are increasing, because of bad ecological condition from one side, and from the other side of genetic influence, and on the top of ladder are allergic diseases of respiratory system. The mayor key process in atopia is continuous and plentiful production of IgE antibody. 

Hyperplasia in goiter may be associated with altered apoptosis thyrocytes. There are numerous techniques for the detection and quantification of apoptosis. Some of them were light microscopy, electron microscopy, flow cytometry, studying the activities of caspase, DNA fragmentation and so on. In patients with multinodular endemic goiter after six months of iodine load, number of apoptotic thyrocytes increased by ten times, Bcl-2 is missing and Bax appeared in thyrocytes. Excess iodine in molecular form causes apoptosis in thyrocytes creating free radicals, mitochondrial damage and release of cytochrome c. Research shows that the level of sFas in the serum of patients with multinodular goiter increased compared to normal controls, it can still point to the reduced expression of Fas protein on the surface of cells that then leads to increased thyroid cell proliferation. Further study of apoptosis in goiter combined morphological and biochemical methods are important for better diagnosis and treatment of diseases.

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. 

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.

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. 

Doppler ultrasound check-up significantly increases a possibility of initial functioning of arteriovenous fistula. The aim of the study was the preoperative evaluation of vascular system of the extremity for creation of arteriovenous fistula for haemodialysis. The examination was organized at Urology and Nephrology Clinic, Clinical Centre "Kragujevac". The examined subjects were 87 patients, 52 (59,8%) male and 35 (40,2%) female, mean age of 61±11,1 years. There were performed the routine biochemical analyses, demographical structure and clinical characteristics (type of anastomosis, fistula placement, arterial blood pressure, lumen size of the artery and vein, measured intraoperatively by Doppler technique). In 72,1% of patients with functioning fistula there was made a terminal-lateral anastomosis, compared to 57,7% of patients with initial non-functioning fistula, there was found a statistically significant difference between the groups p=0,008. Radiocephalic fistula was created in 62,3% of the examined patients with initial functioning , in patients with non-functioning, the distal fistula was created in 38,5% of the examined patients. Regarding the type of the fistula location there was obtained statistically significant difference; p=0,04. There was found a statistically significant difference between the group of patients with initial functioning of arteriovenous and the group without, concerning the intraoperatively measured lumen of the cephalic vein (2±0,29 vs. 2±0,38 mm); p=0,03 (2,1±0,5 vs. 1,8±0,4); p=0,0009. Statistical significance between the groups was also found in the lumen of the cephalic vein verified by the ultrasound (2,1±0,53 vs. 1,8±0,25 mm); p=0,038. Peak of the systolic speed of the radial, corelated to the group of patients with and the group without initial functioning fistula (50 ± 12,42 vs. 40 ± 6,9 cm/sec); (p=0,0026), has statistically significant value. By the correlation of the group of patients with initial functioning and the group of patients without initial functioning, regarding hemoglobin (97 ± 16,1 vs. 88 ± 18,3 g/l); p=0,006 and the level of urea (22,6 ± 12,7 vs. 23,9 ± 9,8); p=0,02, there was found a statistically significant difference. Color Doppler ultrasound has an important role in preoperative evaluation of blood vessels and it represents a meaningful predictive parameter of functioning of arteriovenous fistula.
