Plants are important antioxidant sources. In our study, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of endemic Helleborus vesicarius Aucher ex Boiss.were determined. The aerial parts of the plant samples were dried and extracted with ethanol (EtOH). TAS and TOS values of plant extract were determined using Rel Assay Diagnostics kits. As a result of the studies, the TAS value of H. vesicarius was determined 5.548±0.23, the TOS value was 13.778±0.119 and the OSI value was 0.249±0.009. In this context, the plant has been shown to have significant antioxidant potential.

Abstract. Background: The pathophysiological basis of chronic kidney disease and its complications, including cardiovascular disease, are associated with chronic inflammation and oxidative stress. We investigated the effects of active vitamin D (calcitriol) and synthetic vitamin D analog (paricalcitol) on oxidative stress in hemodialysis patients. Methods: This cross-sectional study was composed of 83 patients with a minimum hemodialysis vintage of one year. Patients with a history of any infection, malignancy, and chronic inflammatory disease were excluded. Oxidative markers (total oxidant and antioxidant status) and inflammation markers (C-reactive protein and interleukin-6) were analyzed. Results: A total of 47% (39/83) patients were using active or analog vitamin D. Total antioxidant status was significantly higher in patients with using active or analog vitamin D than those who did not use (p = 0.006). Whereas, total oxidant status and oxidative stress index were significantly higher in patients with not using vitamin D when compared with the patients who were using vitamin D preparation (p = 0.005 and p = 0.004, respectively). On the other hand, total antioxidant status, total oxidant status, and oxidative stress index were similar between patients who used active vitamin D or vitamin D analog (p = 0.6; p = 0.4 and p = 0.7, respectively). Conclusion: The use of active or selective vitamin D analog in these patients decreases total oxidant status and increases total antioxidant status. Also, paricalcitol is as effective as calcitriol in decreasing total oxidant status and increasing total antioxidant status in patients with chronic kidney disease.

In this study, it was aimed to determine the nutrient concentrations and antioxidant activity of Achillea millefolium L. (Yarrow), which is known to have medicinal properties. For this purpose, macro and micronutrient concentrations, total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of water extract Yarrow plant, which is known to be collected from Divrigi district in Sivas province, were determined. The results have shown that the yarrow plant is sufficient in terms of some macro and micronutrient concentrations, and the nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium from macro elements, iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) from micro elements concentrations were determined as 1.01% N, 0.63% P, 2.43% K, 2.22% Ca, 0.70% Mg, 360.4 mg kg-1 Fe, 47.6 mg kg-1 Zn, 85.5 mg kg-1 Mn and 28.3 mg kg-1 Cu, respectively. It has been determined that its antioxidant potential is moderate. In addition, the plant’s oxidant capacity and oxidative stress index were found to be low.
