Abstract Two model algae Chlorella vulgaris (C. vulgaris) and Raphidocelis subcapitata (R. subcapitata) were generally used to test chemicals with antimicrobial properties during registration process. However, it has been reported that significant sensitivity difference in two algae when exposure to antibiotics. Furthermore, the selection of an appropriate test species play a vital role in evaluate of environmental hazards and risks of compounds. Since the balance between oxidative stress and antioxidant is a crucial factor on alga growth. This experiment is performed to investigate the working of oxidative stress and mechanism of antioxidant defense system of algae under antibiotic stress. A series of concentration of Tylosin (TYN), a macrolide antibiotic, were used to test in this study. Oxidative stress biomarkers (Malondialdehyde (MDA)), non-enzymatic antioxidants (Reduced glutathione (GSH)), antioxidant enzymes (Superoxide dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GP), Glutathione S-transferase (GST)) and photosynthetic pigments were measured to investigate antioxidant defense system. R. subcapitata was significantly inhibited with increasing concentration of TYN, whereas no effects on C. vulgaris. The contents of MDA increased significantly when species were inhibited, and thus, activating the antioxidant system, companying with the significantly increasing of SOD and CAT.

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.
