Introduction: It has been demonstrated that peroxynitrite accompanies acute renal ischemia and contributes to the pathophysiology of renal damage. Therefore, we aimed to investigate the roles of N-acetylcysteine (NAC), a well-known powerful antioxidant, and ebselen (E), a scavenger of peroxynitrite, on renal injury induced by renal ischemia/reperfusion injury (IRI) of rat kidney. Materials and methods: Forty male Sprague–Dawley rats were divided into five groups: sham, renal IRI, renal IRI+NAC, renal IRI+E, and renal IRI+NAC+E. IR injury was induced by 60 min of bilateral renal ischemia followed by 6 h of reperfusion. After reperfusion, kidneys and blood samples were obtained for histopathological and biochemical evaluations. Results: Renal IR resulted in increased malondialdehyde and nitrite/nitrate levels suggesting increased lipid peroxidation and peroxynitrite production and decreased superoxide dismutase and glutathione peroxidase activities. Both NAC and E alone significantly decreased malondialdehyde and nitrite/nitrate levels and increased superoxide dismutase and glutathione peroxidase activities. Additionally in the renal IRI+NAC+E group, all biochemical results were quite close to those of sham group. Histopathologically, the kidney injury in rats treated with combination of NAC and E was found significantly less than the other groups. Conclusions: Both NAC and E are able to ameliorate IRI of the kidney by decreasing oxidative and nitrosative stresses and increasing free radical scavenger properties. Additionally, combination of NAC and E prevents kidney damage more than when each drug is used alone, suggesting that scavenging peroxynitrite nearby antioxidant activity is important in preventing renal IRI.
Objectives To determine the effects of nebivolol on oxidative stress, insulin resistance, adiponectin and plasma soluble P-selectin levels in hypertensive patients in comparison with metoprolol. Material and methods Eighty newly diagnosed hypertensive patients in grade 1 hypertension according to the European Society of Hypertension and European Society of Cardiology guidelines were enrolled in this prospective, blinded, randomized study. Seventy-two patients completed the study. After baseline assessment, each patient was randomly allocated to a 5 mg daily dose of nebivolol (n = 37, 20 male) or a 100 mg daily dose of metoprolol (n = 35, 18 male) and treated for 6 months. Blood pressure, heart rate, oxidative stress (malonyldialdehyde), homeostasis model assessment: insulin resistance, adiponectin and plasma soluble P-selectin levels were measured before and after treatment. Results At the end of treatment, nebivolol and metoprolol significantly decreased blood pressure and heart rate, with a more pronounced bradycardic effect of metoprolol. Nebivolol, but not metoprolol, significantly lowered oxidative stress (P = 0.03), the insulin resistance index (P = 0.003) and plasma soluble P-selectin levels (P = 0.008), and increased adiponectin levels (P = 0.04). Conclusion Nebivolol, in contrast to metoprolol, improved oxidative stress, insulin sensitivity, decreased plasma soluble P-selectin and increased adiponectin levels in hypertensive patients. These beneficial effects of nebivolol may contribute to a reduction in cardiovascular risk in hypertensive patients.
To evaluate ischemia-modified albumin (IMA) in women who had been pregnant with a child suffering from neural tube defect.Samples from 50 women who had been pregnant with an affected child (25 spina bifida, 25 anencephaly) and 25 controls matched for age, gestational age, and body mass index were studied. We measured serum IMA by enzyme-linked immunosorbent assay.Serum IMA was significantly higher in the study group compared to normal pregnancies (p < 0.05). The area under the receiver operating curve was 0.858 for IMA (95% CI, 0.769-0.947), whereas the optimal threshold value of IMA to discriminate between affected children and controls was 0.409 (sensitivity 88%, specificity 80%). The risk for increased IMA in mothers who have conceived a fetus with neural tube defect is 24.5 times higher than in the control group (rr = 24.5, 6.9-86.9, 95% CI) (p = 0.001).This study indicates that serum IMA in women who have conceived a fetus with neural tube defect is significantly higher than that in normal pregnant women.
Crimean-Congo hemorrhagic fever (CCHF) is a public health problem in many countries. Chitotriosidase (ChT) is an enzyme secreted by activated macrophages that catalyzes the hydrolysis of chitin and chitin-like substrates. The goal of this study was to assess the relationship between serum ChT activity and mortality.ChT activities on the first day of hospitalization were analyzed in serum from 46 patients with CCHF and 36 healthy controls. Serum ChT activities and other clinical and laboratory parameters for patients with non-fatal and fatal CCHF were compared.The median ChT activity was increased in all patients with CCHF [189.9 (134.8-246.6) nmol/mL/h]. The median ChT activity in the non-fatal CCHF group [220.2 (180.6-290.1) nmol/mL/h] was higher compared with the fatal CCHF group [29.2 (16.5-45.7) nmol/mL/h] (p<0.001). In univariate analysis, platelet count, lactate dehydrogenase (LDH), and activated partial thromboplastin time were associated with mortality.This is the first study investigating the association of serum ChT enzyme activity with mortality from CCHF. This study suggested that relatively low ChT enzyme activities may be a prognostic marker in patients with CCHF.
