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.

Myeloperoxidase (MPO), a heme enzyme present in the primary granules of polymorphonuclear leukocytes (PMNs) participate in oxygen-dependent microbicidal activity of these cells. During the course of bacterial meningitis plenty of PMNs leave blood vessels and migrate to cerebrospinal fluid (CSF) space, and some of their MPO may become, extracellular. MPO activity in control CSF is low (Me = 0.5 U/L), comparing with patients CSF samples of all three groups of proteinorrachia where elevated values were found already on admission (3.5 U/L, 5.0 U/L and 12.0 U/L, respectively), with highest values found during second lumbal punction (5.5 U/L, 7.5 U/L and 14.0 U/L, respectively). Poor correlation was found between albumin quotient and MPO activity CSF/serum, but significant correlation between MPO in CSF and CSF PMNs count.

Chronic vein insufficiency (CVI) is abnormal functioning of a system of veins resulted from incompetence of vein valves, with or without vein obstruction covering both surface and deep veins. Nowadays there are various standars in the diagnosis of CVI and variations of treatment modalities, which increases the importance of occuracy and foundations of the diagnosis. In the consideration of diagnostic needs of patients with CVI, CEAP classification is suggested. This classification defines clinic categories, etiology of problem, covered anatomical segments and pathological mechanisms of CVI.

+Gz acceleration is unique dynamic stress to organism. Development of this occurrence depends not only to magnitude of acceleration but to onset rate and duration too. The most of former researches pointed to +Gz stress as significant stress to basic physiological mechanisms like cardiovascular and respiratory system. The new study was to examine responses of neuroendocrine and immune system to +Gz stress.

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.

The psychotropic drug addiction is steadily increasing in the subpopulation of the young generation. The objective of this paper is to investigate the degree of psychoticism as a disintegrating personality phenomenon. Psychoticism comprises elements of autism, insensitiveness, aggression, asocialisation. This irregularity in cognitive processes was tested on three groups of people: politoxicomaniacs, psychotic patients and a control group. The DELTA test reported convincingly raised dimensions on the scale of psychoticism: general executive functions (GEI), schyzotypical behaviour (SHD) , paranoia (P), and depression (D), as crucial factors not only for developing addiction but also for achieving long - term and stable abstinence. Apilot study retesting of abstinent persons, has confirmed, after a year's treatment, the change in their behaviour ( by improving all the results on DELTAscale of psychoticism).

Artrial hypertension is a very serious social-medical probleme as such has an epidemic characteristics according to high prevalence at incidence frequency disease of young, a high death rate, there is also a somewhat difficult erly diagnosis at the early stages of illnes due to unspecified clinical examination in majority of diseased. On the basis of etiology, arterial hypertension is divived into: primary (essential) and secondary (symptomatologic). According to the current criteria, primary arterial hypertension is considered to be all the cases where etiology cannot identify only the cause or a specific structural change in a organ. It instead causes a larger number of etiological factors by their group actions which are called risk factors.Including the secondary hypertension all cases at arterial hypertension are classified und there can be seen a specific structural change in an organ and disorder of it's function. The aim of our work was to determinate which were the familiar risk factors in development of arterial hypertension and it's domination to inhabitants of Zubin Potok considering high prevalence of arterial hypertension out of 6500 inhabitants in the infirmary of Zubin Potok, 2450 patients are registrated with arterial hypertension. Examination is performed to 100 patients with primary arterial hypertension by prospectus analysis which are registrated consecutively in the interval of two months by biochemicals parametars, a height of systolic and dyastolic arterial pressure and BMI. By means of questionnaire the rest of risk factors are gathered with a piece of data smoking, alchoholism and stress. During the examination we determined that the most typics risk factor is disorder of metabolism of lypoproteins, and important pathothysiological mechanism in development of arterial hypertension is reduction of HDLcholesterol, which can be one of indirect indentifier of oxidative stress.

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.

Aim of this study was to determine characteristics and correlation between basic anthropometric and spirometric parameters in athletes of different sports and non sportsmen. Measurements were conducted on 140 male and female athletes: volleyball, basketball, soccer, handball players, runners, VESLACI and 60 non sportsmen, 30 female and 30 male. All measurements were conducted in the Laboratory for functional diagnostics at the Department of Physiology, Medical School, Novi Sad. BMI values were normal for all athletes except in handball players, whose average BMI was 25.70+/-2.35 2 kg/m . Average values of body fat percent (BF %) were significantly higher in female athletes, the lowest values were measured in female runners (determined by both methods anthropometry, bioimpedance), while in the group of male athletes the highest body fat was found in basketball players. Statisticaly significant gender difference was found for all anthropometric parameters. Athletes have significantly lower values of BMI and BF% compared to non sportsmen, and males compared to females. Those gender differences are the result of sex determined diferences in body fat distribution, and different length of sports activities. BMI is not a good predictor of body fat content in athletes, because it's high values indicates masculinity rather than fatness. Spirometric parameters show significantly higher values in athletes of both sexes, because ventilatory function is expected as an effect of chronic adaptation on training. Correlation differences between anthropometric and spirometric parameters can be explained by the age differences in our participants and the length of their sports activities.
