Objective: 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 activities 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.
A b s t r a c tWe 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.

Bazı antibiyotiklerin Tip 2 diabetes mellitus'lu hastaların polimorfonüklear lökosit (PNL) fonksiyonları ve PNL'lerin miyeloperoksidaz aktivitesi, glutatyon ile malondialdehit düzeyleri üzerine in vitro etkisi Amaç: Çalışmamızda diabetes mellitus (DM)'lu hastaların polimorf nüveli lökosit (PNL) fonksiyonları ile sağlıklı gönüllülerin miyeloperoksidaz (MPO) aktivitesi, glutatyon (GSH) ve malondialdehit (MDA) düzeylerini karşılaştırıp arasındaki ilişkiyi saptamayı amaçladık. Bunun yanında siprofloksasin, rifampisin ve doksisiklinin PNL fonksiyonları, MPO aktivitesi ve GSH ile MDA düzeyleri üzerine immunomodülatör etkilerini araştırdık. Yöntemler: Çalışmamızda Tip 2 diyabeti olan 13 hasta ve 13 sağlıklı gönüllü yer almaktadır. Antibiyotiklerin PNL fonksiyonları üzerine olan etkileri in vitro koşullarda araştırıldı. PNL'ler (1x10 7 hücre/ml) venöz kandan Ficoll-hypaque gradient santrifügasyon metodu kullanılarak izole edildi. PNL'lerin MPO aktivitesi modifiye O-dianisidin yöntemi, GSH miktarı Ellman yöntemi ve MDA düzeyleri ise Beuge yöntemi kullanılarak belirlendi. Bulgular: DM'lu hasta PNL'lerinin fagositik (p<0.05) ve hücre içi öldürme aktivitesi (p<0.01) sağlıklı gönüllülere göre anlamlı olarak azaldı. Siprofloksasin sağlıklı gönüllü ve tüm hasta PNL'lerinin fagositik ve hücre içi öldürme aktivitesini kontrol değerlere göre anlamlı olarak artırdı (p<0.01 ve p<0.01). Rifampisin, DM'lu hasta PNL'lerinin hücre içi öldürme aktivitesini anlamlı olarak artırdı (p<0.05). Rifampisin ve doksisiklin ise, sağlıklı gönüllü PNL'lerinin fagositik ve hücre içi öldürme aktivitesini kontrol değerlerine göre anlamlı olarak azalttı (p<0.05). Siprofloksasin (2.5 μg/ml) sağlıklı gönüllülerin (p<0.01) ve hastaların MPO aktivitesini ve MDA düzeyini ilaçsız kontrole göre anlamlı olarak artırdı (p<0.01). Ancak aynı ilaç DM'lu hasta PNL'lerinin GSH düzeyini anlamlı olarak azalttı (p<0.05). Sonuçlar: İmmün sistemi bozulmuş Tip 2 DM'lu hastalardaki ve sağlıklı gönüllerdeki MPO aktivitesi ile PNL fonksiyonları arasındaki ilişkinin önemi siprofloksasin ile hücresel immün sistemin desteklenmesi ve PNL'lerin MPO aktivitesi ile beraber PNL aktivitelerinin artışı ile gösterildi.

We also examined the immunomodulatory effects of ciprofloxacin, rifampicine and doxycycline on PMN functions, MPO activity and GSH and MDA levels. Methods: Thirteen patients with T2DM and 13 healthy volunteers were included in the study. The effect of antibiotic...
