Conducting research in the field of respiratory function, by using measuring and testing, has many purposes. First of all, it could show us how lungs function as a whole, but also, it could lead us to the exact location of a disorder. The aim of this paper is to, by employing accurate correlation of the measured variables of the flow/volume and flow/pressure curves, determine the location of the obstruction process in the tracheobronchial tree, in central-upper airways, as well as in a segment of small airways, so called 'silent zones' of the lungs, smaller than 2 mm in internal diameter. This research included 115 healthy people and 106 patients with chronic obstructive lungs disease, of both genders. The following values of the measured lungs' function parameters were found among healthy people (% of predicted value): FVC- 93%; FEV - 91,1 %; 1 FEV x 100/ FVC- 98,7%; MEF - 107,9%; MEF - 87,5%; MEF-98,9%; Rt-147,1%; ITGV-103,3%; SRt- 130,7%. 1 25%FVC 50%FVC Among the patients with chronic obstructive bronchitis, the following results of the examined parameters were gained: FVC- 66,3%; FEV - 54,2%; FEV x 100/ FVC- 80,7%; MEF - 19,3%; MEF - 23,1%; MEF- 40,5%; Rt- 51,2%; 1 1 25%FVC 50%FVC ITGV- 162,1%; SRt- 36,2%. Finally, there was a certain number of the healthy examinees who showed that direct indicators of the air flow resistance (Rt, SRt) were not significantly changed, while indirect indicators of the respiratory tracts obstruction (MEF , MEF ) were reduced, comparing to the expected tabular results.

Malignant tumors of the skin (MTS) are between the most common malignant tumors at human population. Because of their similarities, and more important, their dissimilarities, it is very important to determinate histophologycal type, grading and staging, because they are the most important factors of therapy choise and prognosis. The aim of our work was to examine those parameters, and also to define sex, age and locations distribution, as well as the value of surgical treatment. We analysed biopsy material of Institute of pathology, Medical faculty Priština from 2004-2007. year. We found that squamocellular carcinoma (SCC) and basal cell carcinoma (BCC), and malignant melanoma (MM) were more common at older persons, about 2x more common at male, little bit younger at persons with BCC and MM than SCC. The most common location was skin face; at persons with SCC and BCC significant more common than on all other skin locations. SCC was more common below, and BCC was more common on skin face above imagine line from tragus to the same side lips corner. Average size was about 1,5 cm, and macroscopic they were ulcerous, verrucous and infitrative. Invasive SCC was diagnosed in 2/3 cases in the most early stadium. In opposite MM was diagnosed in late stadium in majority cases. Moderate inflammatory infiltrate was found in most cases of all MTS. MTS was adequate removed in the most part cases.

670 students, of 3rd, 5th and 7th grade, were examined. 50,6% were boys, 526(78,51%) healthy (3<PB<90), that is well nourished students, (257-38,36%) boys and (269-40,15%) girls. There is statistically significant frequency of normally nourished children of 3rd, 5th and 7th grade in comparison to the whole frequency of appearing of the numbered eating disorders (p<0,001). Undernourished (PB) were 18 students (2,68%), 9 boys (1,34%) and 9 girls (1,34%). Malnutrition is statistically the least frequent eating disorder with children of 3rd, 5th and 7th grade. Pre-obese (90<PB<97) were 92 students (13,73%), where 47 were boys (7,01%) and 45 were girls (6,72%). Pre-obesity is statistically the most frequent eating disorder among children of 3rd, 5th and 7th grade (p<0,05). 34 students (5,07%) were diagnosed with obesity, 26 (3,88%) boys and 8 (1,19%) girls. Statistically the obesity appears more often with boys than with girls of the same age (p<0,001). In general the least manifested eating disorder with students of 3rd, 5th and 7th grade, but also in each class separately, is undernourishment, which appears with the same frequency both with boys and girls. Generally the most manifested disorder in nourishment with students of 3rd, 5th and 7th grade, but also in each class separately, is pre-obesity which appears with the same frequency both with boys and girls. The level of obesity is the highest with the students of 3rd grade, and the lowest with the students of 5th grade.

Metabolic syndrome is a common metabolic disorder whose primary feature is abdominal obesity, which is associated with a high prevalence of dyslipidemia, hypertension and glucose tolerance disorders. The goal was, determine BMI in subjects with metabolic syndrome and people with normal body weight, take anthropometric parameters (waist and hip circumference, and calculate WHR and WSR index) to assess the average degree of nourishment and body fat distribution. The research was conducted in Gracanica Health House. The study group consisted of 130 subjects that met the criteria for metabolic syndrome. The control group consisted of 40 randomly selected subjects during medical check-ups. The study group was dominated by female with 83. 08%, followed by 16. 92% of male subjects, with the average age of subjects being 56. 32 years. The average BMI index of the study group was 32. 22 kg/m², which indicates first-degree obesity, while the average BMI index of study group subjects was 24. 67 kg/m², which is within the normal nutrition range. By comparing the average values of anthropometric parameters, we established that the study group subjects had statistically significantly higher average body weight parameters (waist-to-hip ratio p<0,001), while the control group subjects had a higher average of body height (p<0,001). In both, study and control group, male subjects had a normal WHR, which is not the case with women. Therefore, there was a statistically significantly higher number of women with pathological WHR (p<0,001) than of men in both groups. The study group had a statistically significantly higher number of subjects with pathological WHR (p<0,001). The average WSR value (waist/BH) is statistically significantly higher in the control group (p<0,001). Obese individuals had significantly higher values of measured anthropometric intraabdominal fat indicators compared to normally nourished people. 

Theoretical principle of computerized tomography was set by Czech mathematician J. Radon in 1917.The development of computerized tomography is connected with the name of A.M Cormack who, in 1963, started with the research directed at X-ray beam intensity measurement after passing through certain substance.First computerized tomography appartus was installed in Atkinson-Morley hospital in October in 1971 in London. Computerized tomography is based on making transverse(axial) cross-section of body parts,by X-ray beam passing through visible body part and by measurement of X-ray absorption degree using detectors. A cross-section picture of certain body part is obtained on a monitor as a final result of CT examination. A system of picture digitalisation and application of grey scale concept is particularly complex. Basic elements of CT are gentry, patient's bed, high-voltage generator, working and computer console, system for transferring picture on a film or other electronic media. Densimetric tissue values can be measured on the obtained CT picture. A change can be isodense, hypodense or hyperdense. Density change is expressed in Hounsfield units. Contrasting remedies can be applied, during CT, intracanalicular or intravenous. A better quality survey of changes increasing tissue density is obtained using them. CT application is indicated in diseases such as:neurocranium, visceral cranium, spinal column, thorax, abdomen, skeletal, joint and muscular system. X-ray side effects and precaution risks are being described in the text.

Leptin was discovered in 1994, finding, that marked the beginning of a new understanding about white adipose tissue. Up to end of 20th century this tissue was viewed as an inert tissue, devoted to body protection from heat loss and to passively store energy. This static vision, changed with identification of the product of the gene obese (ob) wich accentuated the role of adipose tissue in the physiopathology of obesity-linked diseases, and led to the discovery of various adipokines, many of a pro-inflammatory nature. With emerged knowledge of (WAT)-derived adipokines, it is obvious that they can be now considered as the bond between obesity-related environmental causes, such as nutrition and lifestyle, and the biochemical shifts that lead to metabolic syndrome, inflammatory and/or autoimmune conditions, and rheumatic diseases. This paper deals with reviews of recent adipokine research, with particular emphasis to the role of leptin, adiponectin, resistin, and visfatin in chondrocyte function and skeleton, as well as in inflammatory and degenerative cartilage joint diseases.

Although there is generally world trend in decreasing of number of smokers, expecially in developed part of world, smoking cigarettes still have large importance in morbidity and mortality of modern human population. Taking anamnestics data about smoking habit instruct anaesthesiologist to apply special strategy in general anaesthesia for a reason of possible complications provoked bby a chronic influence of nicotin and other tobbaco ingredients on different organs. In this article we wanted to examine influence of chronic tobbaco smoke exposing on arterial oxygen saturation SaO2 during and short period after general anaesthesia. Research was evaluated on patients in Emergency Center of Clinical Center of Serbia. Patients were divided in two groups (ASAI and II): group I smokers (n=40) and group II nosmokers (n=40). Our investigation has shown no statistical significant difference on SaO2 during general anaesthesia between two experimental groups. Immediately after general anaesthesia and extubation in postoperative period SaO2 dicreases (p<0.001) during transport from operating room to recovery room in both groups of patients,but the level of hypoxemia was significantly higher in smokers group. In this study we demonstrated that tobbaco smoking corellate with postoperative decrease of SaO2 after general anaesthesia, proposing an additional oxygen therapy in early postoperative period.

Strenuous exercises greatly increase oxygen consumption in the whole body, especially in skeletal muscles. Large part of oxygen consumption by the body is reduced to H O and ATP, but smaller part (2-5%) of these tremendious increase 2 oxygen consumption results in an increased leakage of electrons from the mitochondrial respiratory chain, forming various reactive oxygen species-ROS (O ˙ˉ, H O i OH˙). TheseROS are capable of triggering a chain of damaging biochemical and 2 2 2 physiological reactions such as oxidative stress and lipid peroxidatio. There is a groving number of informaztions pointing on important role of free radicals as mediators in inflamation and damage of skeletal muscles after strenuous exercise. The mechanism of exercise induced oxidative stress are not well understood. The mitochondrial electron transport chain, polymorphneutrophil and xanthine oxidase have been identified as major source of intracellular free radical generation during and after exercise. Also the interaction of metmyoglobin and methaemoglobin with peroxides may be also an importante source of oxidative stress during exercise.

Exudative age-related macular degeneration is leading cause of irreversible vision loss in developed countries. Subfoveal localisation of choroidal neovascular membrane is the most difficult form for treatment. At the last three years, the new group of agens well-known as anti-VEGF agens was approved for treatment of exudative AMD. In that purpose, intravitreally administrated agens is recommended. Efficacy and safety of anti-VEGF agens were proved in short-time follow up period.

Nowdays, reaction time is most often used in data processing as a quantitative method and technique for information step and speed processing. The aim of this investigation was to examine everyday work pressure on reaction time nd among students. An examination included 30 students of 2 year of Medicine Faculty 15 males and 15 females. Audible and visual simple reaction time as well as choice reaction time for 2, 4 and 6 stimuli was used for reaction time measurement. Measurements were done three times a day. Achieved results acknowledge statistically significant improvement of reaction time at noon compared to reaction time in the morning in all samples except for visual simple reaction time for male students. For all kinds of stimuli, reaction time were significantly prolonged in the evening in both groups. Therefore, we have concluded that morning activities had positive impact on students functional condition but afternoon activities acted like an additional stress that altered students latent fatigue to clearly observable acute fatigue.
