Objective: Behcet's disease (BD) is a chronic inflammatory disorder characterized by recurrent oral and genital aphthous ulcers, uveitis and skin lesions. Oxidative stress and inflammation have important role in the pathogenesis of BD. The aim of this study was to assess the effect of Nigella sativa (NS) oil administration on malondialdehyde (MDA), total anti-oxidant capacity (TAC), tumor necrosis factor-α (TNF-α), IL-10 and high sensitivity C-reactive protein (hs- CRP) levels in patients with BD. Materials and Methods: In this randomized, double-blind and placebo-controlled clinical trial, 96 BD patients were randomly assigned to NS or placebo groups. Study groups received 1000 mg/day NS oil and placebo soft gels for 8 weeks. Serum levels of TNF-α, IL-10, hs-CRP, MDA and TAC were measured before and after treatment. Results: Eighty-nine individuals completed the study. Significant decreases in the serum levels of MDA and increases in the serum levels of TAC were found in the NS group. However, differences in the changes of MDA and TAC in the NS and placebo groups were not significant. Pre- and post-intervention changes of TNF-α, IL-10 and hs-CRP levels in the NS group were non-significant. Conclusion: NS 1000 mg per day is probably not effective in reducing the inflammatory and oxidative markers in BD.

Objective: The glucose-reducing effects of troxerutin was previously proven. This study was conducted to evaluate troxerutin effect on testicular structure and spermatozoid parameters in type-1 diabetic adult male rats. Materials and Methods: Fifty male Wistar rats were randomly classified into 5 groups as follows: control (C), troxerutin (T), diabetic (DM), troxerutin-treated DM (DT) and insulin-treated DM (DI). Testicular structure, apoptosis, lipid peroxidation and antioxidant activity, and spermatozoid parameters were assessed 4 weeks after initiation of the interventions. Results: The results revealed that diabetes caused testicular stereological changes and significantly increased blood glucose level, testicular MDA content and apoptosis but decreased insulin level, testicular GPX activity, and sperm parameters compared to controls (p Conclusion: Taken together, troxerutin, comparable to insulin, effectively improved DM-induced testicular dysfunction and sperm parameters in diabetic rats and these effects might be mediated through troxerutin’s anti-apoptotic effects.
