UDK: 630*38:625.711.84(497.6 Sarajevo) The time period of forests opening and construction of forest truck roads in the analyzed area is longer than half of century. In such long time interval different types of vehicles for transport of timber assortments have been applied. Due to this fact technical elements of constructed roads are different. The vehicles currently used for the transport of timber assortments cause an accelerated destruction of forest truck roads due to inappropriate carriage way quality. Besides traffic load the forest truck roads are exposed to permanent atmospheric influences. The above specified and other reasons condition obligatory and regular maintenance and reconstruction of forest truck roads depends on the current condition of forest truck roads as well as on the plans for further use. In this article the condition of forest truck roads in the Forest management regions of Sarajevo Canton has been determined. The most frequent types of damages and causes of their occurrence have been registered. The methods for maintenance and rehabilitation-reconstruction of forest truck roads have been selected and their costs have been calculated. In the time when construction of new kilometers of forest truck roads is more and more rare, timely, adequate and financially justified maintenance of the existing network of forest truck roads is one of the key question for their undisturbed use. On the basis of results obtained in this research the guidelines for the time period and the ways of maintenance of forest truck roads have been given. The application of these guidelines should help in achieving of the best and most economical total results through the long-term use of forest truck roads.

Abstract The purpose of this study was to evaluate the genotoxic potential of components leached from two conventional self-curing glass-ionomer cements (Fuji IX and Ketac Molar), and light-curing, resin modified glass-ionomer cements (Vitrebond, Fuji II LC). Evaluation was performed on human lymphocytes using alkaline and hOGG1 modified comet, and micronucleus assays. Each material, polymerised and unpolymerised, was eluted in extracellular saline (1 cm2 mL-1) for 1 h, 1 day, and 5 days. Cultures were treated with eluates using final dilutions of 10-2, 10-3, and 10-4. Alkaline comet assay did not detect changes in DNA migration of treated cells regardless of the ionomer tested, polymerisation state, and elution duration. Glass ionomers failed to significantly influence micronucleus frequency. No oxidative DNA damage in treated lymphocytes was observed using hOGG1 modified comet assay. Obtained results indicate high biocompatibility of all tested materials used in the study under experimental conditions. Sažetak Svrha istraživanja bila je procijeniti genotoksični potencijal komponenata koje izlučuju dva konvencionalna samopolimerizirajuća stakleno-ionomerna cementa (Fuji IX i Ketac Molar) te svjetlosno polimerizirajući i smolom modificirani stakleno-ionomerni cementi (Vitrebond, Fuji II LC). Istraživanje je provedeno na ljudskim limfocitima primjenom alkalnog komet testa, komet testa modificiranog hOGG1 enzimom te mikronukleus testa. Svaki materijal, polimerizirani i nepolimerizirani, eluiran je u fiziološkoj otopini (1 cm2 mL-1) tijekom jednog sata, jednog dana i tijekom 5 dana. Kulture limfocita tretirane su eluatima u razrjeđenjima 10-2, 10-3 i 10-4. Alkalnim komet testom nisu zabilježene promjene u migraciji DNA iz tretiranih stanica bez obzira na ispitani ionomer, vrstu polimerizacije i trajanje elucije. Izloženost staklenim ionomerima nije značajno utjecala na učestalost mikronukleusa. Primjenom hOGG1 modificiranog komet testa nije zamijećeno oksidativno oštećenje DNA u tretiranim limfocitima. Dobiveni rezultati upućuju na visoki stupanj biokompatibilnosti svih testiranih materijala koji su se koristili u eksperimentalnim uvjetima.

Background and purpose — Some patients have persistent symptoms after total hip arthroplsty (THA). We investigated whether the proportions of inferior clinical results after total hip arthroplasty—according to the 5 dimensions in the EQ-5D form, and pain and satisfaction according to a visual analog scale (VAS)—are the same in immigrants to Sweden as observed in those born in Sweden. Methods — Records of total hip arthroplasties performed between 1992 and 2007 were retrieved from the Swedish Hip Arthroplasty Register (SHAR) and cross-matched with data from the National Board of Health and Welfare and also Statistics, Sweden. 18,791 operations (1,451 in immigrants, 7.7%) were eligible for analysis. Logistic and linear regression models including age, sex, diagnosis, type of fixation, comorbidity, surgical approach, marital status, and education level were analyzed. Outcomes were the 5 dimensions in EQ-5D, EQ-VAS, VAS pain, and VAS satisfaction. Preoperative data and data from 1 year postoperatively were studied. Results — Preoperatively (and after inclusion of covariates in the regression models), all immigrant groups had more negative interference concerning self-care. Immigrants from the Nordic countries outside Sweden and Europe tended to have more problems with their usual activities and patients from Europe and outside Europe more often reported problems with anxiety/depression. Patients born abroad showed an overall tendency to report more pain on the VAS than patients born in Sweden. After the operation, the immigrant groups reported more problems in all the EQ-5D dimensions. After adjustment for covariates including the preoperative baseline value, most of these differences remained except for pain/discomfort and—concerning immigrants from the Nordic countries—also anxiety/depression. After the operation, pain according to VAS had decreased substantially in all groups. The immigrant groups indicated more pain than those born in Sweden, both before and after adjustment for covariates. Conclusion — The frequency of patients who reported moderate to severe problems, both before and 1 year after the operation, differed for most of the dimensions in EQ-5D between patients born in Sweden and those born outside Sweden.

Background: HCV infection is characterized by a tendency towards chronicity. Acute HCV infection progresses to chronic infection in 70% of cases. Hepatitis C virus infection can cause progressive liver injury and lead to fibrosis and eventually cirrhosis. The degree of histologic fibrosis is an important marker of the stage of the disease. One of current standard treatment for CHC infection is the combination of PEG-IFN α and ribavirin. Objectives: The aim of the study was to investigate the effect of the therapy with Peginterferon alfa-2a or alfa-2b plus Ribavirin on evolution of liver fibrosis in patients with chronic hepatitis C. Also, our aim was to examine whether there was a difference between the genders in the efficacy of these antiviral therapy. Our goal also was to determine effect of the therapy with Peginterferon alfa-2a or alfa-2b plus Ribavirin on evolution of liver steatosis in patients with chronic hepatitis C. Patients and Methods: A retrospective study was made of chronic hepatitis C patients who had been treated from 2005 to April 2014 at the Clinic of Gastroenterohepatology, Clinical Center University of Sarajevo. We reviewed 40 patient medical records to collect demographic, epidemiological and clinical information, as information on liver biopsies that was performed prior to the antiviral therapy and FibroScan® test that was performed after the antiviral therapy. For the processing of data SPSS (Statistical Package for the Social Sciences Program) for Windows, ver. 21.0 statistical software was used. Comparisons between qualitative and quantitative variables were performed using the Student t-test. Mann Whitney U test was used to compare differences in variables such as fibrosis stage and steatosis grade. A value of p<0.05 was considered as statistically significant. Results: After treatment, there was a statistically significant increase in the number of patients with no fibrosis (p<0.05). There was no statistically significant reduction in the number of patients with cirrhosis (F4) (p>0.05). There was significantly higher decrease of fibrosis progression at the patients that were in an mild-to-moderate fibrosis (F1/F2/F3), patients that were in advanced stage of fibrosis (F4) at the time of the pre-treatment did not have a statistically significant fibrosis reduction. We found significant association in evolution of fibrosis after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2a (12,5) kD with ribavirin (p< 0.05). We also found significant association in evolution of steatosis after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2a (12,5) kD with ribavirin (p < 0.05). There was statistically significant differences (p<0.05) between genders within fibrosis qualitative evolution. Conclusions: There were significant regression of fibrosis especially at the patients that were in an mild-to-moderate fibrosis (F1/F2/F3), patients that were in advanced stage of fibrosis (F4) at the time of the pre-treatment did not have a statistically significant fibrosis reduction after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2b (12,5) kD with ribavirin. Our results showed significant improvement in steatosis in patients infected with HCV after treatment with PEG-IFN α2a (40) kD and PEG-IFNα2b (12,5) kD with ribavirin. Those results provides further evidence for direct involvement of HCV and antiviral therapy in the pathogenesis of hepatic steatosis. Female gender showed a higher degree of fibrosis reduction.
