Aim: The prognostic value of circulating antibodies to oxidized low-density lipoprotein (anti-oxLDL) in patients with coronary heart disease is not completely clear. We aimed to investigate the association between levels of anti-oxLDL in three groups of patients with different grades of severity of coronary heart disease. Patients and methods: The study included 101 patients classified into three groups: one (N=35) with acute myocardial infarction (AMI), a group (N=35) with angiographicallly proven coronary artery disease (APCAD), and a group without angiographicallly proven coronary artery disease (N=31) designated as a control group. Levels of IgG anti-oxLDL antibodies were meausured by enzyme-linked immunosorbent assay. Results: Mean anti-oxLDL value was significantly higher in patients with AMI than in patients with APCAS (1342.1±581.5 mIU/ml vs. 553.0±183.3 mIU/ml, p<0.001), as well as compared with control group (1342.1±581.5 mIU/ml vs. 246.5±114.3, p<0.001). Similarly, significant difference in anti-oxLDL levels was found between the patients with APCAS and control group (p<0.001). Conclusions: The present study showed that elevated levels of anti-oxLDL are positively related with a severity of coronary artery disease. Hence, elevated levels of anti-oxLDL may identify patients with unstable coronary heart disease. Oxidized LDL in circulating plasma could serve as a marker of cardiovascular events.

The natural habitat of Gardnerella vaginalis is a vagina since it could be located among 69% of women who have no signs of vaginal infection and in the vagina of as many as 13.5% girls. G. vaginalis is almost certainly identified among women diagnosed with bacterial vaginosis as well as in the urethra of their sexual partner. The increase in prevalence and concentration of G. vaginalis among patients diagnosed with this syndrome confirms that G. vaginalis plays a significant role in its pathogenesis. In our research, based on Amsel criteria for three or more clinical signs of bacterial vaginosis, it was diagnosed in 20.5% of women with subjective problems of vaginal infection, and in 48.80% of women with subjective symptoms characteristic of this disease. G. vaginalis was isolated from vaginal secretion of women without clinical signs characteristic of bacterial vaginosis. In 2.58% of cases it was solitary, while in 1.28% it was found in combination with other aerobic and anaerobic bacteria and, in 1.28% women combined with Candida albicans. The isolation of G. vaginalis was significantly increased (p<0.05) in the group of women with clinical signs of bacterial vaginosis in comparison to the group of women without these signs. Frequent recurrence of bacterial vaginosis, which is found in 20-30% of women within a three months treatment, is explained as reinfection with other biotype of G. vaginalis, different from a source biotype or as a consequence of wrong treatment. Following Piot biotype scheme, biotypes 2., 3. and 7. G. vaginalis are significantly more often isolated from women who suffer from bacterial vaginosis. Biotype 7. G. vaginalis, isolated from the group of women without clinical signs of bacterial vaginosis, accounted for 2.58% cases. Following Benit biotype scheme, biotypes IVa, IVc and IIc were identified in 12.90% cases, while biotypes IIIa, IIa, Ia, IVb, IIb were found in 6.45% cases. Lipase-positive isolates of G. vaginalis were significantly more frequently accompanied by the syndrome of bacterial vaginosis.

In this study we analyzed microbiology results of tuberculosis in urinary system, in the area of Tuzla canton in period since 1993 to 2005 year. For microbiological diagnosis we tested samples of whole morning urine by method of concentration and homogenization by Petroff and inoculated on Loewenstein culture media. All grown culture was identified biochemical by production of niacin, reduction of nitrate and production of heat labile catalase. In this investigated period we tested 121,945 samples of different biological materials on Mycobacterium tuberculosis: sputum 89,433, gastrolavate 5,122, broncholavate 1,337, pleural exudation 1,356, punctuates 1,711, liquors 179, stools 149, blood 4, urine 22,654 samples. All urine samples were taken from 4,192 patients. Positive culture is found in 358 urine samples or in 1, 58%, or 173 patients or 4, 13%. From total 4,759 microbiologically diagnosed patients with all different types of tuberculosis in this period of time, with pulmonary tuberculosis there was 4,495 or 94, 45% patients and 264 or 5, 55% with extrapulmonal types of tuberculosis. Tuberculosis of urinary system is microbiologically diagnosed in 173 or 3, 63% patients out of total number of diagnosed tuberculosis cases. Tuberculosis of urinary system is diagnosed in 115 women and 58 men. In both sexes it was most often diagnosed in age of 65 to 74 year and in women in age of 45 to 54 year and in man in age 25 to 34 year. Tuberculosis of urinary system is more common in patients from Tuzla then from other town in Tuzla canton. It is also more common in patients that were treated in Clinic then those who were treated ambulatory. We can conclude that distance of place of living from place of microbiology laboratory significantly influence on microbiologically diagnostic of tuberculosis of urinary system.

Aim of this research was to investigate diagnostic value of discovering of antibody on A60 antigen in patients who were tested for presents of Mycobacterium tuberculosis in there biological samples. We tested a samples of sputum, gastric juice, urine, cerebrospinal fluid and punctate from group of 353 patients who were suspected for tuberculosis. In all patients we were looking for antibodies classes A60 antigen. We used immune chromatographic "Hexagon TB" test, Germane company "Human Geselschaft fur Biochemica und Diagnostica". From 353 patients we found 58 (16.43%) patients with positive BK, 79/22,38%) patients with positive Lowenstein culture and 122 (34,55%) patients with antibody in sera on A60 antigen. Patients who were BK and Lowenstein positive, have had antibody in 94,23% cases, Patients who were BK negative and Lowenstein positive have had antibodies in 70,37% cases and patients who were BK negative and Lowenstein negative have had antibody in 19,03% cases. Patients with BK positive and Lowenstein negative results have had antibody in 50,00% cases. Difference between results is significant (p<0,01). From 122 patients with positive antibodies, 52 were BK positive and 68 have had positive Lowenstein cultures. From 231 patients with no antibody, just 6 were BK positive and 11 Lowenstein positive. In 62 patients with positive antibodies, were BK and Lowenstein negative. We confirmed that antibody on A60 antigen in microbiological positive patients are more often then in microbiological negative patients (p<0,001).

Aim of this work is to show the level of prevalence of patients infected with resistant strains Mycobacterium tuberculosis in Canton Tuzla. In the period of 1996-2003 year we tested 87,408 samples of different materials on existence of Mycobacterium tuberculosis. Among all samples there were 66,128 sputum, 14,599 urines, 3,817 gastric juice, 1,174 materials from broncholavage and 547 other samples. Microscopically it was found 4,380 smear-positive samples and 6,365 samples were positive on Loewenstein medium. Positive sputum had 1,917 patients, and positive culture had 3,018 patients. Resistance test was done on streptomycin, isoniazid, rifampicin and ethambutol with standard proportional method for 2,662 patients. Totally sensibile were 2,570 or 96.54%, and restant were 92 or 3.46% patients. Patients infected with mono-drug resistant strains Mycobacterium tuberculosis were 71 or 2.67%, and poli-drugs resitant 21 or 0.78%. There were 16 patients or 0.60% infected with multi-drugs resistant strains. Time of bacteriological negativization for the patients infected with resistant strains was in the average 8.19 months, for the patients infected with mono-drug resistant strains was 2.75 months and for infected with multi-drugs resistant strains was 32 months. It is concluded that region of Canton Tuzla has high level of bacteriological prevalence but low level of prevalence of patients infected with resistant strains Mycobacterium tuberculosis in the this period of time, and it is significantly lower then earlier periods, thanks to national tuberculosis control program and system of directly observed treatment.

The aim of this study was to made assessment of health effects in 37 workers exposed to gasoline, and its constituents at gasoline stations between 1985 and 1996. Thirty-seven persons who had been exposed to gasoline for more than five years were examined. The evaluation included a medical / occupational history, haematological and biochemical examination, a physical exam, standardized psychological tests, and ultrasound examination of kidneys and liver. The groups were identical in other common parameters including age, gender (all men), and level of education (P<0. 05). The data were compared to two control groups: 61 healthy non-exposed controls and 25 workers at gasoline stations exposed to organic lead for only nine months. Peripheral smear revealed basophilic stippling and reticulocytosis. We found in chronic exposed gasoline workers haematological disorders: mild leukocytosis (7 of 37), lymphocytosis (20 of 37), mild lymhocytopenia (3 of 37), and decrease of red blood cells count (11 of 37). Results indicated that they have suffered from liver disorders: lipoid degeneration of liver (14 of 37), chronic functional damages of liver (3 of 37), cirrhosis (1 of 37). Ultrasound examination indicated chronic kidney damages (8 of 37). These results significantly differed from those of controls (P< 0.05). In 13 out of 37 workers at gasoline stations exposed to gasoline for more than 5 years the symptom of depression and decreased reaction time and motor abilities were identified. The summary of diseases of workers exposed to organic lead and gasoline are discussed.
