Strenuous physical activity is known to generate reactive oxygen species to a point that can exceed the antioxidant defense system and lead to oxidative stress. Dietary intake of antioxidants, plasma enzymatic (superoxide dismutase, glutathione reductase [Gr], and glutathione peroxidase [GPx]) activities, nonenzymatic (total antioxidant status [TAS], uric acid, α-tocopherol, retinol, α-carotene, β-carotene, lycopene, and lutein + zeaxanthin) antioxidants, and markers of lipid peroxidation (thiobarbituricacid-reactive substances [TBARS]) and muscle damage (creatine kinase [CK]) were measured in 17 elite male kayakers and canoeists under resting conditions and in an equal number of age- and sex-matched sedentary individuals. Athletes showed increased plasma values of α-tocopherol (p = .037), α-carotene (p = .003), β-carotene (p = .007), and superoxide dismutase activity (p = .002) and a lower TAS level (p = .030). Antioxidant intake (α-tocopherol, vitamin C, and β-carotene) and plasmatic GPx, Gr, lycopene, lutein + zeaxanthin, retinol, and uric acid levels were similar in both groups. Nevertheless, TBARS (p < .001) and CK (p = .011) levels were found to be significantly higher in the kayakers and canoeists. This work suggests that despite the enhanced levels of antioxidants, athletes undergoing regular strenuous exercise exhibited more oxidative stress than sedentary controls.

ABSTRACT Introduction Periodontitis is a common problem affecting a significant population of the world. For the assessment of oxidative stress of an individual, total oxidation status (TOS) and total antioxidant capacity (TAOC) are the significant biomarkers. Hence, we planned the present study to assess malondialdehyde (MDA), TOS, TAOC levels, and oxidative stress index (OSI) in generalized aggressive periodontitis (GP) and chronic periodontitis (CP) patients. Materials and methods The present study included assessment of 40 CP patients, 40 GP patients, and 40 healthy controls. Clinical assessment of all the subjects was done by measuring the probing depth (PD), clinical attachment (CL), gingival index (GI), gingival bleeding index (GBI), and plaque index (PI). Salivary and serum samples were taken and assessed by standard procedures as described previously in the literature. All the values were assessed and compared. Results Significant results were obtained while comparing all the periodontal parameters in between various study groups. Mean serum MDA levels in the CP, GP, and control group were found to be 0.68, 0.65, and 0.61 µM respectively. Statistically nonsignificant results were obtained while comparing the serum MDA levels in between the three study groups. Significant results were obtained while comparing the mean serum and salivary TOS values, TAOC values, and OSI in between various study groups. Conclusion In periodontitis patients, oxidative stress was significantly higher in comparison with healthy subjects. Clinical significance Oxidative parameters do play a significant role in the pathologic profile of periodontitis. How to cite this article Tripathi V, Singh ST, Sharma V, Verma A, Singh CD, Gill JS.

AbstractAlthough it is accepted that an important correlation exists between the physical exercise and the oxidative stress status, the data regarding the levels of the main oxidative stress markers after physical training have been difficult to interpret and a subject of many controversies. There are also very few studies regarding the effects of short-time exercise on the oxidative stress status modifications. Thus, in the present report we were interested in studying the modifications of some oxidative stress markers (two antioxidant enzymes-superoxide dismutase and glutathione peroxidase, a lipid peroxidation parameter — malondyaldehide, the total antioxidant status and protein carbonyl levels), from the serum of rats that were subject to one bout of five minutes exercise on a treadmill, when compared to a control sedentary group. In this way, we observed a decrease of superoxide dismutase specific activity in the rats which performed the exercises. Still, no modifications of glutathione peroxidase specific activity were found between groups. In addition, increased levels of malondyaldehide and protein carbonyls were observed in the rats subjected to exercises. In conclusion, our data provides new evidence regarding the increase of the oxidative stress status, as a result of a 5-minutes bout of treadmill exercising in rats, expressed through a decrease in the SOD specific activity and the total antioxidant status and also an increase of the lipid peroxidation and protein oxidation processes.

 Objective: This study aimed to investigate the effect of onion (Allium cepa var. aggregatum G. Don) on serum uric acid level and total antioxidant status of normal and induced hyperuricemic rats.Methods: A total of 36 male Sprague-Dawley rats were divided equally into six groups, and 250 mg/kg of potassium oxonate was injected intraperitoneally on day 1, 3, and 7 to induce hyperuricemia in rats. 7 d consecutively of treatment were given to the rats by oral gavage. Serum uric acid level was measured 2 h after the induction on day 1, 3, 7, and 14. Blood plasma was obtained at day 14 to measure its total antioxidant status. The rats were sacrificed by taking out their liver and kidney for histopathological evaluation.Results: The results showed that onion juice lowered the serum uric acid level in dose-dependent manner. The highest dose (10.5 g/kg/day) appeared to possess the inhibitory effect almost similar to allopurinol. There was an increase in total antioxidant status in a hyperuricemic group treated with onion juice compared to control groups but insignificant. By viewing the histological profile, onion showed to have a protective effect toward the liver damage by hyperuricemia. However, this was not happened in kidney.Conclusion: Onion lowered the serum uric acid level, but its protective effect toward liver and kidney remained ambiguous. Further investigation with the increase of parameters and inclusion of analytical test of bioactive compound in red onion is recommended for the future studies.
