In our work we analyzed utilisation of antibiotics for systemic use at the Surgical Clinic of the Clinical Hospital Centre - Pristina in Gracanica in 2007. and 2008. Data on antibiotic utilization were delivered on the basis of drug dispensing records from the Central Hospital Pharmacy during the two-years period. Antibiotics were distributed inside the ATC/DDD system in accordance with WHO guidelines. Quantitative antibiotics' utilisation was expressed as number of defined daily doses per 100 patient-days (DDDs/100 PD). Overall use of antibiotics in 2007 was 123.37 DDDs/100 PD, and 125.09 DDDs /100 PD in 2008. Three most utilized antibiotics in 2007. were cefuroxime 24.26 DDDs/100 PD (19.66 % of total antibiotics' use), ceftriaxone 16.65 DDDs/100 PD (13.49 %), and cephalexin 15.78 DDDs/100 PD (12.79 %). In 2008. the most utilized were ceftriaxone 23.23 DDDs/100 PD (18.57 %), cefuroxime 22.53 DDDs/100 PD (18.01 %), and co-trimoxazole 19,55 DDDs/100 PD (15.63 %). Qualitative and quantitative part of the consumed antibiotics was mainly in accordance with the results of similar researches in our country.

Researches with micronutrients are getting more and more important in science and also in practice. In this view zinc, chromium, copper and selenium are having a special role in preventing micro- and macrovascular diabetic complications, as integral components of antioxidant enzymes (superoxide dismutase and glutathione peroxidase) and also as cofactor of enzymes and hormones involved in the metabolism of glucose and lipid. The aim of this study was to evaluate the effects different doses of zinc on glycemia and parameters of antioxidative defense: superoxide dismutase (SOD) and total antioxidant status (TAS), and correlation glycoregulation with antioxidant system of the alloxan-induced diabetic rabbits. The study was conducted on fourteen New Zealand rabbits of both sexes, weighing 2 to 3.5 kg. Experimental diabetes was induced in rabbits by intravenous injection of alloxan (80 mg /kg BW). Three weeks after induced experimental diabetes, rabbits were treated orally appropriate doses of chelated zinc: I dose - 15 mg, after a washout period (10 t ), II dose - 25 mg, af- 1/2 ter a washout period, III dose - 50 mg. Blood samples were taken at specific time intervals: before alloxan induced diabetes, after alloxan induced diabetes, after application the first dose of 15 mg of zinc, after application of a second dose of 25 mg of zinc, after application of third dose of 50 mg of zinc. The zinc preparation did not cause a statistically significant reduction in serum glucose level when administered in single doses 15, 25 and 50 mg in experimentally induced diabetic rabbits. However, the activity of superoxide dismutase (SOD) was significantly increased after single dose preparations of zinc at a dose 15 mg (p<0,05), 25 mg (p<0,001) and 50 mg (p<0,001) in relation to the activity recorded before the application of zinc. Also, after the application first, second, and than third dose of zinc in diabetic rabbits was recorded statistically significant increase of TAS in relation to the value recorded before the application of zinc (p<0,001). Glucose concentrations negatively correlated with superoxide dismutase activity. This indicates that oral application of zinc preparation can reduce the harmful effects of oxidative stress in diabetes.

The combination of aspirin and ticlopidine has been proven to reduce the frequency of haemorrhagic and vascular complications after coronary artery stenting, but also can cause serious hematological side effects. The purpose of this study was to evaluate the effect and interactions aspirin and ticlopidine on hematological variables. Thirty two Wistar rats were divided in four groups and they received intraperitoneal one of the following treatments for 4 days: group I - control, group II aspirin (50 mg/kg BM), group III - ticlopidine (125 mg/kg/day) and group IV - aspirin+ticlopidine combination (50 mg/kg/day+125 mg/kg/day). Hematological variables were determined at once after taking the sample of blood. Relationship between measured variables was determined by calculating linear correlation coefficient (r). The hematocrit, haemoglobin and red blood cell were significantly decreased in group treated with aspirin+ticlopidine combination compared to control (p< 0,05). Neutrophil and platelet count weren't significantly different in treated groups, but were slightly decreased in groups treated with ticlopidine and aspirin+ticlopidine combination. Between hematocrit and platelet count in control group of rats was noticed negative and medium correlation (r=-0,41), in groups treated with ticlopidine and aspirin+ticlopidine combination positive and medium correlation (r=0,52; r=0,69). Based on obtained results it can be observed significant decreased hematocrit, haemoglobin and red blood cell in group treated with aspirin+ticlopidine combination. The negative correlation between hematocrit and platelet count in control group becomes positive after the treatment with ticlopidine alone and aspirin+ticlopidine combination.

Without a knowledge of how drugs are being prescribed and used, it is difficult to suggest measures that would support rational use of drugs and improve prescribing habits in hospitals. In our work we analyzed utilization of antibiotics for systemic use at the Surgical Clinic of the Clinical Hospital Centre - Pristina in Gracanica in 2007. and 2008. on the basis of dispensing records of drugs issued from the Central Pharmacy to the Surgical Clinic for those two years. Antibiotics were distributed according to ATC classification, and antibiotics' utilisation was expressed in number of defined daily doses used per 100 patient-days (DDDs/100 PD). We analized qualitative and quantitative participation of different groups of antibacterials for systemic use. Òhe results of our study were in accordance with available results of similar studies in our country and in the neighbouring environment
