Introduction: The aim of this study is to investigate the potential antioxidant and anti-inflammatory effects of thymoquinone (TQ) to improve acute bacterial prostatitis (ABP) induced by Pseudomonas aeruginosa. Material and Methods: A total of 42 male Wistar albino rats were divided into 7 groups as follows: control, ABP (24, 48, and 72 h), and TQ-ABP (24, 48, and 72 h). The prostate tissue samples were assayed for prostate tissue malondialdehyde (MDA) and nitric oxide(NO) levels, and catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX) activities. Sections were examined for characteristic histological changes, and a histological scoring system was used. Results: When the ABP groups given TQ (24, 48, and 72 h) were compared to the ABP groups not given TQ, the levels of MDA and NO and the GPX activity were found to be significantly lower in the groups given TQ. Concerning SOD values, the TQ-ABP-72 group was lower in comparison with the ABP-72 and control groups, but statistically higher than the TQ-ABP-48 group (p < 0.05). Concerning CAT activity, only the TQ-ABP-72 and ABP-72 groups had a significant difference with the control group. TQ improved prostate histology significantly only in the TQ-ABP-24 group compared to the ABP-24 group (p < 0.001). Conclusion: Our study demonstrated for the first time that ABP induced by P. aeruginosa had an oxidative effect on prostate tissue and could regress following TQ administrationas shown withthe biochemical and histological findings.
PurposeMetabolic syndrome and obesity have been advocated to be risk factors for the development of overactive bladder (OAB). Additionally, insulin resistance is the underlying mechanism of metabolic syndrome. We aimed to investigate the association of insulin resistance with overactive bladder in female patients.MethodsWe prospectively conducted the study in our urology department. Female patients aged between 30 and 76 years old applied to our policlinics with or without OAB symptoms were enrolled. One hundred and twenty-two patients with OAB and 62 age-matched controls without OAB were included into the study. Fasting serum insulin, glucose, high-density lipoprotein (HDL-c), and triglycerides levels were measured. Insulin resistance value was obtained via the homeostasis model assessment of insulin resistance (HOMA-IR) calculator. The chi-square and Mann-Whitney U tests were used to compare differences in variables.ResultsSerum insulin level was found higher in female patients with OAB (11.5±6.2 µU/mL) relative to controls (6.4±2.1 µU/mL), statistically significant (P=0.036). In addition, HOMA-IR was significantly found higher in the OAB group, 2.86 (0.76 to 17.04) in comparison to controls, 1.32 (0.67 to 224), P=0.018. High-density lipoprotein cholesterol levels (HDL-c) were significantly found lower in females with OAB.ConclusionsInsulin resistance can be associated to overactive bladder and may play significant role in pathogenesis.
Vascular impairment was found to be associated with LUTS in both men and women. Atherosclerosis-related vascular risk factors are also known to be related to LUTS and both disorders may have pathogenic interactions.
