Öğe Antimicrobial activity of resins obtained from the roots and stems of Cedrus libani and Abies cilicia(Maik Nauka/Interperiodica, 2002) Kizil, M; Kizil, G; Yavuz, M; Aytekin, CThe antimicrobial activity of the ethanol extract of resins obtained from the roots and stems of Cedrus libani and Abies cilicia has been studied, using the disc diffusion method. The results obtained indicate that crude extracts of the resins of both plants are highly efficient in preventing the growth of microorganisms.Öğe Antimicrobial activity of the tar obtained from the roots and stems of Pinus brutia(Taylor & Francis Ltd, 2002) Kizil, M; Kizil, G; Yavuz, M; Aytekin, ÇThe antimicrobial activity of the crude and methanol, hexane, chloroform. petroleum ether, ethyl acetate and n-butanol extracts of tar obtained from the roots and stems of Pinus brutia Ten., used in the folk medicine of Turkey, were screened in vitro for antimicrobial activity against clinically isolated bacterial strains: Staphylococcus aureus ( 15 isolates), Streptococcus pyogenes ( 12 isolates), Escherichia coli (17 isolates) and the yeast fungus Candida albicans (3 isolates) by the paper disc diffusion method. Results revealed that a crude extract of the tar is highly effective against all tested microorganisms by preventing their growth to a significant extent. All the organic extracts showed similar moderate antimicrobial activity against tested microorganisms at a concentration of 80 mug/mL. The results demonstrate that the crude tar extract has a very broad spectrum of activity, and suggests that it may be useful in the treatment of various microbial infections, The results suggest that traditional folk medicine could be used a guide in our continuing search for new natural products with potential medicinal properties.Öğe Behcet's disease and renal failure(Oxford Univ Press, 2003) Akpolat, T; Diri, B; Oguz, Y; Yilmaz, E; Yavuz, M; Dilek, MBackground. The aims of this study were (i) to investigate the prevalence of Behcet's disease (BD) among dialysis patients in Turkey, (ii) to report the clinical characteristics of patients with BD and endstage renal disease (ESRD), (iii) to evaluate the effect of ESRD on course and activity of BD and (iv) to analyse the published data about BD and renal failure. Methods. A questionnaire investigating BD among dialysis patients was submitted to 350 dialysis centres and we obtained the data for 20 596 patients from 331 dialysis centres. We submitted a second questionnaire regarding clinical characteristics of the patients with BD and ESRD. The PubMed and Web of Science databases were used for the analysis of BD and renal failure. Results. Fourteen patients with BD were determined and the prevalence of BD was 0.07% among 20 596 dialysis patients in Turkey. None of the patients has had a new manifestation of BD after initiation of haemodialysis treatment. The analysis of previous data about renal BD demonstrated 67 patients with renal failure. Conclusions. The most common cause of renal failure in BD is amyloidosis. Routine urine analysis and measurement of serum creatinine and blood urea nitrogen levels are needed for early diagnosis. Vascular access-related problems are common and the activity of BD appears to decrease in patients with ESRD after initiation of haemodialysis.Öğe The rate, risk factors, and outcome of fungal peritonitis in CAPD patients(Sage Publications Inc, 2000) Taskapan, H; Özener, Ç; Ates, K; Akçiçek, F; Yavuz, M; Yilmaz, ME; Ataman, R[Abstract Not Available]
