UDK 582.632.2:581.9(497.6) In this paper is given an overview of the rare occurrence of beech with oaklike bark (Fagus sylvatica var. quercodies) in Bosnia and Herzegovina, which is recorded for the first time by Karlo Malý in 1934. In addition to basic information about the distribution of this taxon we gave a detailed description of a one its remarkable recent tree from Kreševo area. These unusual phenomena induce scientific interest and require special protection and conservation actions.

UDK 630*6:630*43(497.6 Prozor-Rama)          630*43:630*6(497.6 Prozor-Rama Despite of the significant activities on the forest fires prevention, number of forest fires is constantly growing worldwide causing tremendous direct and indirect damages. Direct damages are referring to the losses on timber and other forest products, fire fighting and remediation costs as well as costs of fire sites restoration. Indirect damages are referring to the negative impacts of forest fires on various ecosystem services and overall conditions of environment. Despite of the fact that indirect damages could be far greater than direct ones, in most of the cases in Bosnia- Herzegovina, they are not included in the assessment of the damages and methodology for their calculation is not developed yet. The goal of this paper is to conduct the economic valorisation of direct and indirect damages from forest fires at the territory of Prozor-Rama municipality in 10-years period in which the scope and frequency of the forest fires were determined. The methodology that is used in this paper is developed by European experts on assessment of socio-economic damages from forest fires in Europe (PETTENELLA et al, 2008). Formula for calculation of damages of some functions and values of forests are partially modified due to the specific conditions of forest management practice and characteristics of forest stands, while some of them were excluded from assessment since they required additional research for their valuation. Calculated values of the damages are 11 times greater than those that are presented in the Register of the damages from forest fires of the Public Forest Enterprise „Šume Herceg-Bosne“. Modified method could be a sound basis for development of methodology for assessment of the damages from forest fires and total economic valuation of forest ecosystems in Bosnia-Herzegovina.

Aim To detect polymorphisms of 23 Y-chromosomal short tandem repeat (STR) loci, including 6 new loci, in a reference database of male population of Bosnia and Herzegovina, as well as to assess the importance of increasing the number of Y-STR loci utilized in forensic DNA analysis. Methods The reference sample consisted of 100 healthy, unrelated men originating from Bosnia and Herzegovina. Sample collection using buccal swabs was performed in all geographical regions of Bosnia and Herzegovina in the period from 2010 to 2011. DNA samples were typed for 23 Y STR loci, including 6 new loci: DYS576, DYS481, DYS549, DYS533, DYS570, and DYS643, which are included in the new PowerPlex® Y 23 amplification kit. Results The absolute frequency of generated haplotypes was calculated and results showed that 98 samples had unique Y 23 haplotypes, and that only two samples shared the same haplotype. The most polymorphic locus was DYS418, with 14 detected alleles and the least polymorphic loci were DYS389I, DYS391, DYS437, and DYS393. Conclusion This study showed that by increasing the number of highly polymorphic Y STR markers, to include those tested in our analysis, leads to a reduction of repeating haplotypes, which is very important in the application of forensic DNA analysis.

CONFLICT OF INTEREST: NONE DECLARED Goal The goals of this study are to: a) determine the prevalence of diabetic polyneuropathy (DPNP) in hospitalized patients with diabetes mellitus (DM) type 2; b) determine the frequency of DPNP in hospitalized patients with type 2 DM in relation to gender, duration of diabetes, fasting blood glucose and HbA1c; c) identify the dominant DPNP symptoms and the presence of variable risk factors in hospitalized patients; and d) determine the frequency and motor nerve conduction velocity of n. peroneus (electroneuromyography) in relation to the treatment of type 2 DM in hospitalized patients with DPNP. Material and methods The study was conducted on 141 patients diagnosed with type 2 diabetes who were hospitalized at the Neurological clinic of Clinical Center of Sarajevo University in the period from June 1 2009 to June 1 2010. All patients included in the study were older than 18. Values determined for all subjects are: age, sex, dominant symptoms, duration of type 2 DM, fasting blood glucose, HbA1c, motor conduction velocity of n. peroneus, diabetes risk factors (hyperlipidemia, hypertension, smoking, alcoholism, obesity) and DM treatment type. Results Of 141 patients with type 2 DM, DPNP was confirmed in 50 patients (35.5%). Men were slightly more represented in the total sample (51.8%). In a sample of patients with DPNP, there were slightly more male patients (n=26; 52%). The average age of patients with DPNP was higher in men (58.3±12.5) (p<0.05). The average age of the patients with DPNP was 55.1± 13.2. Average values of fasting glucose was higher in the group of patients with DPNP (11.032±5.4 mmol/l) compared to patients without DPNP (9.7±2.8 mmol/l) (p<0.05). Mean values of HbA1C were higher in patients with DPNP (8.212±3.3%) compared to patients without DPNP (6.9±2.6%) (p<0.05). Analysis of DM duration between patients with and without DPNP did not show statistically significant difference (chi-square=3.858, p>0.05). In both groups, most of the patients had duration of DM over 10 years, with a minimum duration of DM of 12 months. There are statistically significant differences in applied DM therapy by gender (chi-square=11.939, p<0.05). Hypertension was more frequent in women (79.2%:69.2%), hyperlipidemia was equally presented in both sexes (50%:50%), obesity was more prevalent among women (25%:7.7%), while alcoholism and smoking were more frequent in men (7.7%:0%; 34.6%:8.3%). There are statistically significant differences in the prevalence of risk factors by gender (chi-square=10.013, p<0.05). Conclusions The DPNP incidence was higher in patients with longer duration of the disease, but without significant gender differences. Fasting blood glucose and HbA1c were significantly higher in patients with DPNP compared to patients without DPNP (p<0.05). The dominant symptoms of DPNP were paresthesia (44%) and hypoesthesia (28%). Regarding variable risk factors, the most common were hypertension and hyperlipidemia, without statistical significance in gender distribution, while smoking was significantly more common in men than women (34.6%:8.3%). DPNP was present in 43.2% of men who use insulin therapy, while 54.2% of women with DPNP used oral therapy. The lowest frequency of DPNP was found in patients treated with combined therapy. Motor conduction velocity of n. peroneus was significantly lower in men using insulin therapy and/or combined therapy (p<0.05), whereas in patients on oral therapy there was no significant gender difference. Timely DM type 2 diagnosis with proper treatment and electromyoneurographic monitoring (especially in older men) can prevent onset of diabetic polyneuropathy and contribute to its successful treatment.
