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.

Apart from great frequency of epithelian, especially preinvasive changes, some very rear diseases common for other lower parts of genital tract (cervix and vulva), are vaginal epithelian changes and especially vaginal intraepithelial neoplasia (VAIN). That's the reason why we don't usually think about this disease, which can have very serious consequences, especially in late discovering of changes in the stadium of invasive malign disease.The aim of this work was to diagnose all pathological changes on vagina: benign, premalign and malign, according to the age of female patients. Biopsy and operative material taken from 1331 female patients treated in Ginecology and Obstetrics Clinic “Narodni front” in Belgrade, were used in this study. The most diagnosed benign changes was condylomata acuminate (42%). Out of 20 cases of premalign changes, VAIN I was diagnosed in 5 cases (25%) as a slight degree of premalign changes, while VAIN II and VAIN III were diagnosed in 5 cases as a severe degree of premalign lesions. Out of 11 cases, there were 3 cases (27.27%) of invasive planocellar vagina carcinoma with histological degree G1N1. 8 cases (72.72%) were with histological degree G2N2, while there were not a single case with histological degree G3N3. Planocellar vagina carcinoma is the most common in the age of 41-50.

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.

Oral isotretinoin is highly effective in treatment of patients with severe acne, but has been concerned with causing occasional depression. Clinicians should be alert to the high prevalence of depression among people with acne. Isotretinoin has many unwanted effects, among which possible unproven effects on mood have to be included. If depression or other mood change occurs, then isotretinoin treatment should be discontinued. If treatment is continued, psychiatric support should be obtained.

Inhibins are glycoprotein hormones of which there are two molecular forms, inhibin A and inhibin B. Classically, inhibin is known to have a negative feedback effect on pituitary follicle-stimulating hormone secretion. The fetoplacental unit produced inhibin throughout pregnancy. Inhibin Ais the predominant molecular form of inhibin in maternal circulation from 4 week of gestation. Although the precise biological function of inhibin Ain pregnancy is unclear, it is evident from recent studies that inhibin A could be a better marker of placental function than human chorionic gonadotropin because of its shorter half-life. The possible clinical application for the measurement of inhibin Ain early pregnancy could be in predicting miscarriage , Down's syndrome, preeclampsia and fetal growth restriction in the first and/or second trimester before the onset of yhe clinical symptoms. Inaddition, several evidences underline the potential role and the clinical usefulness of their measurements in the diagnosis, prevention,prognosis and follow-up of different gestational pathologies such as:threatened abortion, placental tumors, hypertensive disorders of pregnancy,intrautherine growth restriction,fetal hypoxia.The measurement of inhibin Aand activin Ainto the biological fluids of pregnancy will offer in the future further possibilities in early diagnosis,prediction and monitoring pregnancy diseases.

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.

The fractures of the tibia are mainly the fractures of the long bones. In the department of the orthopedic in Kosovska Mitrovica, 45 of patient with fracture of the lower leg had been treated with using the closed method. It had been the linear fractures in the 84% of the treated cases.The most number of the patients were treated in the hospital for 5 days. In our healing we are noticed the folowed complications in the treated patients: the major infections around the pin were in the 4% of the treated patients (2 patients),the fat embolism were in the 2% of the treated patients (1 patient),the pseudoarthrosis were in the 4% of the treated patients (2 patients). Aplication the extrafocal fixat r by Mitkovich using the closed method made possible that the fracture became stable in fast and simply way with the minnor invasion at the soft tissues and with this are made the conditions for splicing of the fractures.
