Pharmacy students’ knowledge and attitudes about antibiotics in Kosovo

Objective: The main objective of this study was to assess the knowledge and attitude among Pharmacy students of the University of Prishtina in regards to the antibiotics. Methods: 144 pharmacy students at the University of Prishtina were recruited in this study to complete a self-administered questionnaire. The total number of questions in this questionnaire was eight (8), covering two (2) major themes: self-report of the current and past antibiotic use and behavior; and anticipated prescription behavior of antibiotics upon graduation. The data was statistically analyzed through using SPSS for Windows. Descriptive analysis was employed, and the results were expressed in frequency and percentages. Results: The results showcased a good knowledge of antibiotic among students. The most common answer of students' knowledge about antibiotics was good or moderate (82 %), while 63.2% of the subjects used antibiotics by self-decision, most of them (45 %) for sore throat. Upon graduation, 56.9 % of the students will not sell antibiotics without prescription and 85.4% think that module for rational use of antibiotics is very necessary to be inside the pharmacy syllabus. Conclusion: The study showed good and moderate knowledge of pharmacy students regarding the antibiotics. Half of them use antibiotics by self-decision but the majority of them stated that they will not serve the antibiotics without medical prescription. Specific modules and training for proper antibiotic use should be implemented within the Pharmacy program in The Faculty of Medicine.

Protection by polyphenol extract from olive stones against apoptosis produced by oxidative stress in human neuroblastoma cells

Objective: We evaluated the protective activity of an extract from a by-product such as olive stones, through its ability to inhibit H2O2 induced apoptosis in the SH-SY5Y human neuroblastoma cell line. Material and methods: To such end, 20,000 cells/well were cultivated and differentiation with retinoic acid was initiated. Once the cells were differentiated, apoptosis was induced with and without H2O2 extract. Finally, cDNA extraction was performed, and pro-apoptotic genes Bax and anti-apoptotic genes Bcl-2 were analyzed. Quantification of the gene expression was performed using the GAPDH gene marker. Results: Cell viability with the extract is 97.6% (SD 5.7) with 10 mg/l and 62.8% (SD 1.2) to 50 mg/l, using 10 mg/l for the biomarker assay. The retinoic acid differentiated SH-S cell line (10 µM) shows a clear apoptosis when treated with H2O2 150 µM, with a Bax/Bcl-2 ratio of 3.75 (SD 0.80) in contrast to the differentiated control cells subjected to H2O2 and with extract, which have the same ratio of 1.02 (SD 0.01-0.03). Conclusion: The olive stone extract shows anti-apoptotic activity in the provoked cell death of SH-SY5Y human neuroblastoma cells in their normal state, defending them from oxidative stress which produces a significant increase in the apoptotic gene ratio in contrast to anti-apoptotic genes (Bax/Bcl-2).
