IntroductionIn this study, we aimed to determine the protective effects of hesperidin, a citrus flavonoid, in a model of testicular ischemia/reperfusion injury in rats.Material and methodsForty-two pubertal male Wistar-Albino rats were divided into six groups: group 1 – control; group 2 – 50 mg/kg hesperidin (low dose hesperidin) used without torsion (LH group); group 3 – 100 mg/kg hesperidin without torsion (HH group); group 4 – torsion/detorsion group (T/D); group 5 – T/D + 50 mg/kg hesperidin treatment group (T/D + LH); and group 6 – T/D + 100 mg/kg hesperidin treatment group (T/D + HH). Hesperidin was given to the treatment groups 30 min before detorsion. After the fourth hour of reperfusion, orchiectomy was performed on the rats under anesthesia. The tissue samples were examined histologically and biochemically.ResultsIn the T/D group testicular malondialdehyde (MDA) levels were increased significantly (p < 0.001) whereas superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) levels were decreased compared to the control and other groups. However, hesperidin caused the effect of T/D to become closer to normal biochemical values. In addition, the histological examinations showed that T/D caused damage in the testis but hesperidin reduced this effect. The effects of hesperidin were found to be dose dependent. Thus, applying high doses would generate greater therapeutic effects.ConclusionsIn a rat testicular T/D model we observed biochemical and histological damage due to ischemia. However, high and low dose applications of hesperidin were shown to have protective effects against this damage. Therefore, the aforementioned citrus flavonoid may provide positive results in cases of testicular torsion.
BACKGROUND: There is limited data about ICU, short and long-term mortality prediction of severe CAP with neutrophil-to-lymphocyte ratio (NLR): N-terminal proB-type natriuretic peptide (NT-proBNP): C-reactive protein (CRP). AIM: Besides the known severity indexes of ICU, can NLR, NT-proBNP, CRP predict ICU, short and long term mortality? METHODS: A retrospective cohort study was carried out in a level III ICU of a tertiary training hospital for chest diseases and thoracic surgery. RESULTS: Over the study period, a total of 143 patients were enrolled in the study. The APACHE II scoring showed a signifi cantly higher predicting performance for ICU mortality (p = 0.002). The performance for predicting short term mortality NLR (p = 0.039) and long term mortality NTproBNP (p = 0.002) had a signifi cantly higher performance. The survival analysis revealed that mortality was signifi cantly higher in patients with CURB65 score ≥ 4 (p = 0.047). CONCLUSION: NLR, NTproBNP > 2000pg/mL can be used to predict pneumonia severity in ICU alike CURB65 and PSI. Higher NLR, APACHE II and atrial fi brillation can cause an important mortality factor in long term. Consequently, clinicians should take an attention for good cardiac evaluation and cardiac follow-up of patients with CAP (Tab. 4, Fig. 3, Ref. 36). Text in PDF www.elis.sk.
Objective: Celiac disease (CD) is a gluten-triggered immune enteropathy caused by a genetic predisposition. Recent papers suggest that CD is increasingly recognized by extraintestinal findings. The aim of this study was to investigate the effect of CD on hearing pathway including the olivocochlear efferent system in children. Methods: Forty-one pediatric CD patients and 31 controls were included in the study. Both groups were evaluated with audiometry, tympanometry, transiently evoked otoacoustic emission (TEOAE), distortion product otoacoustic emission (DPOAE), and contralateral suppression of the TEOAE. Results: The threshold at 250 Hz of the patients with CD was significantly higher (p < 0.05 in CD compared to control group, p < 0.0001). The signal to noise ratio (SNR) amplitudes in DPOAE testing and the SNR amplitudes with and without contralateral acoustic stimulus in TEOAE testing were significantly lower at 1,000 Hz in the CD compared to the control group. There was no significant difference between the CD and the control group regarding contralateral suppression amplitudes. Conclusion: CD seems to have an important impact on the auditory system, and results in an elevation of the thresholds at 250 Hz on audiometry and a decrease in the amplitudes of DPOAE and linear TEOAE at 1,000 Hz in children.
