Publication Open Access Effect of antibiotics on polymorphonuclear leukocyte functions and myeloperoxidase activity, glutathione and malondialdehyde levels in allergic asthma(2015-03-31) RAYAMAN, ERKAN; Rayaman, Pervi̇N; Rayaman, Erkan; Çevi̇Kbaş, Adi̇Le; Demi̇Rtunç, Refi̇K; Özer Şehi̇Rli̇, Ahmet; Alagöz, Şeyda Gül; Gürer, Ümran SoyoğulWe investigated the effect of ciprofloxacin, rifampicine and doxycycline on myeloperoxidase (MPO) activity, glutathione (GSH) and malondialdehyde (MDA) levels in allergic asthma patients and healthy volunteers. Polymorphonuclear leukocytes (PMNs) were isolated with ficoll-hypaque gradient centrifugation method. MPO activity was assayed with modified o-dianisidine, GSH by Ellman's and MDA levels by Beuge's method. PMN functions and MDA levels of patients significantly decreased when compared with healthy volunteers. Ciprofloxacin significantly increased PMN functions, MPO activity and MDA levels of both groups. We have demonstrated that ciprofloxacin has beneficial effects on MPO activity and PMN functions in allergic asthma patients and healthy volunteers.Publication Metadata only Bazı bitki ekstreleri ile saf fenolik bileşiklerin probiyotik ve patojen mikroorganizmalar üzerine antimikrobiyal aktivitesinin araştırılması(2019-12-10) RAYAMAN, PERVİN; RAYAMAN, ERKAN; TAŞKIN, TURGUT; KARPUZ E., RAYAMAN P., RAYAMAN E., TAŞKIN T.Publication Metadata only Probiyotik ürünlerden izole edilen laktik asit bakterilerinin ultrasonikasyon sonrası antimikrobiyal etkinliğinin belirlenmesi(2023-08-15) RAYAMAN, PERVİN; RAYAMAN, ERKAN; BİNGÖL ÖZAKPINAR, ÖZLEM; Bolat G., RAYAMAN P., RAYAMAN E., BİNGÖL ÖZAKPINAR Ö.Giriş ve Amaç: Yeterli miktarlarda alındığında intestinal sistemi düzenleyerek konakçı sağlığı üzerine faydalı etkilere sahip canlı mikroorganizma suşları olarak tanımlanan probiyotiklerin bağırsak epiteliyal bariyer fonksiyonunu iyileştirdiği, immünomodülatör yanıtları düzenlediği, toksin reseptörlerini bozduğu, inhibitör maddeler ürettiği, çeşitli mekanizmalar kullanarak patojen mikroorganizmaları inhibe ettiği bilinmektedir. Dolayısıyla çalışmamızda, çeşitli probiyotik ürünlerden izole edilen laktik asit bakterilerinin ultrasonikasyon sonrası antimikrobiyal etkinliğinin belirlenmesi hedeflenmiştir. Gereç ve Yöntem: Çalışmamızda; Lactobacillus fermentum ATCC (Amerikan Tipi Kültür Koleksiyonu) 14931, ev yapımı kefirden izole edilen Lactobacillus kefiri ve eczane preparatından izole edilen Lactobacillus rhamnosus türü mikroorganizmaların in vitro koşullarda Escherichia coli ATCC 11229, Staphylococcus aureus ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Salmonella typhimurium ATCC 14028, Klebsiella pneumoniae ATCC 4352 bakterileri ve Candida albicans ATCC 10231 mayası üzerine olan antimikrobiyal aktivitesi spot on lawn yöntemiyle belirlenmiştir. Çalışmamızda bulunan mikroorganizmalar Marmara Üniversitesi Farmasötik Mikrobiyoloji Anabilim Dalı’nın kültür stok koleksiyonundan temin edilmiştir. Çalışmamızdaki Laktobacillus türleri 15 ml’lik Falcon tüplerine aktarılmış ve MRSA (Mann Rogosa Sharpe Agar) içeren petrilere damlatılarak inkübe edilmiştir. İnkübasyon sonrası probiyotik mikroorganizmalara ultrason cihazında ms 73 prob, %50 genişlik ayarlanarak; 6 dakika boyunca ultrasonik homojenikatör uygulanmış ve MRSA besiyeri içeren petrilerin yüzeyine 5 μL damlatılarak inkübe edilmiştir. İnkübasyon sonrası probiyotik mikroorganizmaların bulunduğu petri plaklarının üzerine McFarland 0,5 standart bulanıklığına ayarlanmış bakteriler ve McFarland 1 standart bulanıklığına ayarlanmış maya süspansiyonu içeren yumuşak agar dökülmüş ve petriler bakteriler için 24 saat, maya için ise 48 saat süre ile 37°C’de inkübe edildikten sonra oluşan inhibisyon zonlarının çapı elektronik kumpas yardımı ile mm olarak ölçülüp kaydedilmiştir. Bulgular ve Sonuç: Çalışmada yer alan tüm probiyotik mikroorganizmalar ultrasonikasyon sonrası Escherichia coli ATCC 11229, Staphylococcus aureus ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Klebsiella pneumoniae ATCC 4352 patojenlerine karşı başlangıç değerine göre daha fazla antimikrobiyal etki göstermiştir. Lactobacillus fermentum ve Lactobacillus kefiri türlerinin Candida albicans’a karşı başlangıçta etki edemezken ultrasonikasyon sonrası inhibisyon zonu oluşturduğu tespit edilmiştir. Sonuç olarak ultrasonikasyon işleminin probiyotik ürünlerden izole edilen laktik asit bakterilerinin antimikrobiyal etkinliğini arttırdığı gösterilmiştir. Çalışmamızın bu alanda yapılacak araştırmalara ışık tutacağı kanısındayız.Publication Open Access Potential Adjuvant Effects of Nigella sativa Seeds to Improve Specific Immunotherapy in Allergic Rhinitis Patients(KARGER, 2010) GÜRBÜZ, BURÇAK; Isik, Huelya; Cevikbas, Adile; Gurer, Umran Soyogul; Kiran, Bayram; Uresin, Yagiz; Rayaman, Pervin; Rayaman, Erkan; Gurbuz, Burcak; Buyukozturk, SunaObjective: To investigate the effects of Nigella sativa seed supplementation on symptom levels, polymorphonuclear leukocyte (PMN) functions, lymphocyte subsets and hematological parameters of allergic rhinitis. Subjects and Methods: Twenty-four patients randomly selected from an experimental group of 31 (mean age 34 years) sensitive to house dust mites with allergic rhinitis and a control group of 8 healthy volunteers (mean age 23 years) were treated with allergen-specific immunotherapy in conventional doses for 30 days. After a month of immunotherapy, 12 of the 24 patients and the 8 healthy volunteers were given N. sativa seed supplementation (2 g/day orally) for 30 days. The remaining 12 patients continued only on immunotherapy during the same period. The other 7 patients were given 0.1 ml saline solution subcutaneously once a week as a placebo. The symptom scores, PMN functions, lymphocyte subsets and other hematological parameters were evaluated before and after all treatment periods. Results: There was a statistically significant increase in the phagocytic and intracellular killing tivities of PMNs of patients receiving specific immunotherapy, especially after the addition of N. sativa seed. The CD8 counts of patients receiving specific immunotherapy plus N. sativa seed supplementation significantly increased compared to patients receiving only specific immunotherapy. PMN functions of healthy volunteers significantly increased after N. sativa seed supplementation compared to baseline. Conclusion: N. sativa seed supplementation during specific immunotherapy of allergic rhinitis may be considered a potential adjuvant therapy. Copyright (C) 2010 S. Karger AG, BaselPublication Open Access Antimicrobial effect of probiotic microorganisms onclinical and standard Staphylococcus aureus isolates(2023-12-01) RAYAMAN, PERVİN; RAYAMAN, ERKAN; TETİK N., RAYAMAN P., RAYAMAN E., ADALETİ R.In this study we aimed to identify probiotic microorganisms in various pharmacy preparations, market and homemade probiotic products and investigate the antimicrobial effect of these microorganisms on clinical and standard Staphylococcus aureus isolates. The probiotic microorganisms were isolated from probiotic products mentioned above, then identified by Matrix Assisted Laser Ionization Mass Spectrophotometer (MALDI-TOF, Biomeriux) and also by conventional methods. The tolerance of these probiotic microorganisms to different salt, pH and temperature conditions was also detected. The antimicrobial activity of the specified probiotic microorganisms on S. aureus was designated by using spot on lawn and agar well diffusion methods. In our study among 16 probiotic products, 27 various probiotic microorganisms were specified by MALDI-TOF. Additionally, 15 of these probiotic microorganism species had an isolated reliability value above 90%. In our study 10 probiotic microorganism species, 7 of which were different from each other were found to maintain their viability in three various pH, salt and temperature conditions. These probiotic microorganisms were Lactobacillus rhamnosus (P.2 probiotic pharmaceutical product), Enterococcus gallinarum (homemade whey), Lactobacillus kefiri 1 (homemade kefir), Bacillus megaterium (homemade pickled juice), Lactobacillus kefiri 2 (homemade kefir), Lactobacillus rhamnosus (P.1 company preparation) Lactobacillus plantarum (P.3 company preparation), Bifidobacterium spp (M.4 company pure kefir), Enterococcus faecium (P.3 company preparation). We determined that Lactobacillus plantarum isolated from homemade whey had the highest antimicrobial activity on clinical MRSA 3 (Methicillin resistant Staphylococcus aureus) strain (inhibition zone =45.62 mm ± 0.84. Also, we have found that, probiotic microorganisms isolated from pharmacy preparations, market and homemade probiotic products showed antibacterial effect on clinical and standard Staphylococcus aureus by spot on lawn method. We designated that besides probiotic microorganisms isolated from various pharmacy preparations, probiotic microorganisms isolated from market and homemade products were efficient against clinical and standard S. aureus isolatesPublication Metadata only Microbiological quality and portion analysis of döner sandwiches(2017-03-01) OMURTAG KORKMAZ, BURCU İREM; RAYAMAN, ERKAN; RAYAMAN, PERVİN; SOYOĞUL GÜRER, ÜMRAN; OMURTAG KORKMAZ B.
