LANGUAGE NOTE | Document text in English; abstract also in Chinese. This study investigated the resting levels of malondialdehyde plus 4-hydroxy 2-(E)-nonenal (MDA+4-HNE) in plasma, erythrocyte superoxide dimutase (SOD) and glutathione (GSH) in 12 long-distance runners (LR), 12 weight lifters (WL), and 12 age match sedentary nonathletes (SN). The subjects were asked to maintain the lifestyle and original training (Monday to Friday) and were requested not to take any medicines and supplementation two weeks ago before sampling. No significant differences were found in MDA+4-HNE levels among three groups. The LR group had lower erythrocyte SOD activities than SN group (p <0.05). Additionally, the erythrocyte GSH concentrations in WL group was significantly lower than LR and SN groups (p <0.05). The results indicated that the adaptation and changes in resting antioxidant status would be different due to various exercise training modes. Furthermore, athletes should take the antioxidant supplementation appropriately to overcome the high oxidative stress cause by heavy training. 本實驗比較經長期運動訓練之12位舉重選手、12位長跑選手，以及12未受訓練的坐式生活者，其休息狀態下血液中抗氧化數 值之差異。抗氧化數據包括血漿中之MDA+4HNE，紅血球中之過氧化物歧化酶(superoxide dismutase; SOD)之活性及穀胱甘肽(glutathione; GSH)之含量。受試者維持其原本之生活型態及訓練(星期一至星期五)，從兩個星期前即不能服用藥物及營養補充劑。結果顯示三組間血漿中脂質過氧化產物MDA+4HNE之濃度並無明顯差異，長跑選手紅血球SOD之活性明顯較坐式生活者來得低(p<.05)，舉重選手紅血球GSH含量明顯較其他兩組來得低(p<.05)。結果顯示，不同的訓練可能會造成不同型式的氧化壓力，經過長期之適應後，體內的抗氧化狀態也有所差異。此外，為了抵抗高度訓練所造成之氧化壓力，運動員應該適當的補充抗氧化劑。

Biochemical Indices

The purpose of this study was lo compare zinc and copper biochemical indices of antioxidant status and their relationship in elite athletes of different modalities: aerobic with high-impact (triathletes, n = 10 and long-distance runners, n = 12), anaerobic with high-impact (short-distance runners, n = 9), and anaerobic with low-impact (short-distance swimmers, n = 13). The influence of recent dietary intake and body composition was also evaluated. A venous blood sample was drawn 16-20 hr after competition for the following measurements: packed-cell volume and hemoglobin in blood; copper and zinc in plasma and erythrocytes; ceruloplasmin in plasma; superoxide dismutase activity and metal-lothionein in erythrocyles; and erythrocyte osmotic fragility. Zinc and copper intakes were not different in the athlete groups and did not affect the biochemical indices measured. Athletes of the long-distance high-impact aerobic modalities had higher indices of antioxidant protection (erythrocyte zinc, superoxide dismutase activity, and metallothionein) than those of the short-distance low-impact modalities, suggesting that there is adaptation of the antioxidant capacity to the specific training. Significant correlations were observed in all athletes between erythrocyte zinc, superoxide dismutase activity, and metallothionein consistent with the importance of an adequate zinc status in the response of antioxidant mechanisms to intense exercise.

The Impact

Objective. The aim of the study was to estimate the impact of whole body cryotherapy (WBC) on oxidative stress when performed in a closed cryochamber on patients with ankylosing spondylitis (AS). Material and methods. The effect of ten WBC procedures lasting 3 minutes a day with a subsequent 60-minute session kinesiotherapy on oxidative stress in male AS patients (WBC group n=16) was investigated. To assess the disease activity, the Bath Ankylosing Spondylitis Diseases Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) were calculated. The WBC group was compared to the kinesiotherapy only (KT; n=16) group. The routine parameters of oxidative stress (antioxidant enzymatic and nonenzymatic antioxidant status, lipid peroxidation products, total oxidative status (TOS), and oxidative stress index (OSI)) were estimated one day before the beginning and one day after the completion of the research program. Results. After the completion of the treatment in the WBC group, a significant decrease of oxidative stress markers (TOS and OSI) and a significant increase of total antioxidant status were observed. The erythrocyte activity of glutathione peroxidase, glutathione reductase decreased significantly in both groups, but the differences of activity of that enzymes prior to post treatment values (Δ) in the KT group were significantly higher as compared to the WBC group. The activity of erythrocyte catalase and plasma ZnCu isoenzyme of superoxide dismutase showed a decreased tendency; erythrocyte total superoxide dismutase activity showed an increased tendency in the WBC group after the completion of the treatment. The BASDAI and BASFI decreased significantly in both groups, but the differences of value indexes prior to post treatment (Δ) were significantly higher in the WBC than KT group. Conclusion. WBC performed in a closed cryochamber decreases oxidative stress and improves BASDAI and BASFI indexes in male patients during the active phase of ankylosing spondylitis.

Sixty individuals including 17 competitive weight lifters (CWL), 12 competitive long-distance runners (LDR), 7 amateur (noncompetitive) weight lifters (AWL), 14 heavy controls (HC), and 10 light controls (LC) were studied at supine rest and during static exercise at 40% of maximal voluntary contraction. Blood pressures were similar in all groups at rest (R) and exercise (EX), but the heart rate (HR) and calculated double product (DP) of the LDR were lower at rest (HR: 53 +/- 2.9 beats/min, DP: 6,346 +/- 402) and at fatigue (HR: 78 +/- 5.4 beats/min. DP: 12,739 +/- 1,011) compared to the control group (R-HR: 69 +/- 2.2 beats/min, DP: 8,553 +/- 372; EX-HR: 97 +/- 3.5 beats/min, DP: 16,345 +/- 836). The LDR demonstrated higher end-diastolic volume index (EDVI) and higher end-systolic volume index (ESVI) at rest (EDVI: 84 +/- 3.7, ESVI: 31 +/- 2.7 ml/m2) and at the time of fatigue (EDVI: 90 +/- 5, ESVI: 37 +/- 2.7 ml/m2) compared to the LC group (R-EDVI: 61 +/- 4.4, ESVI: 22 +/- 2.2; EX-EDVI: 75 +/- 3.4, ESVI: 27 +/- 3.2 ml/m2). The CWL, AWL, and control groups had similar HR, DP, and cardiac volumes at rest and during exercise. These data suggest that competitive endurance (dynamic exercise) training alters the cardiovascular response to static exercise. On the other hand, weight lifting (static exercise) training does not alter the cardiovascular response to static exercise.

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.

Introduction: Oxidative stress plays critical role in aging and pathogenesis of neurodegenerative and neuropsychiatric disorders. However, its role in suicidal behavior is not clarified yet. Consequently, we aimed to evaluate the oxidant-antioxidant status in the serum of suicide attempters in Ilam city. Methods: 50 suicide attempters and 40 control subjects (volunteers) aged 18-35 years were studied in the current experiment. In order to consider the oxidant-antioxidant status, serum levels of malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD) and the total antioxidant capacity (TAC) were measured. Results: Serum levels of SOD enzyme and TAC were significantly lower in suicide attempters group compared to the controls. Furthermore, serum NO level was significantly higher in the suicide attempters in compare with the controls. Interestingly, the serum level of MDA was significantly lower in the suicide attempters compared to the controls. Conclusion: Presence of oxidative stress without MDA elevation, which has been detected in suicide attempters can be considered as a biochemical hallmark in suicide behavior.

Objective: To evaluate the oxidative stress and antioxidant defense in patients with chronic myeloid leukemia.Background: Chronic myeloid leukemia is a myeloproliferative disorder associated with a characteristic chromosomal translocation called the Philadelphia chromosome. Reactive oxygen species and other free radicals mediate phenotypic and genotypic changes leading from mutation to neoplasia in all cancers, including chronic myeloid leukemia. We evaluated patients with chronic myeloid leukemia by observing their oxidative status and antioxidant defense.Methods: Using serum from 40 clinically diagnosed cases of chronic myeloid leukemia as well as 40 healthy controls, we measured the concentration of thiobarbituric acid, levels of protein carbonylation, total antioxidant status, catalase, superoxide dismutase, glutathione peroxidase, vitamins A and E, and the trace elements zinc, magnesium, and selenium. Results: We found significantly increased levels of serum malonyldialdehyde and protein carbonyl in patients with chronic myeloid leukemia in comparison to healthy individuals, and significantly decreased levels of the antioxidants and micronutrients thiobarbituric acid, catalase, superoxide dismutase, glutathione peroxidase, vitamins A and E, zinc, magnesium, and selenium. These data suggest cellular damage occurring at the level of lipids and proteins.Conclusion: These findings indicate a link between low levels of antioxidants and cellular damage in patients with chronic myeloid leukemia, supporting the idea that oxidative stress may play a role in the pathogenesis of chronic myeloid leukemia.

Estrogen can putatively act as an antioxidant and protect tissues from exercise-induced oxidative stress. To test the in vivo efficacy of estrogen, the effects of 2 weeks of daily estrogen (40 µg·kg-1 body weight beta-estradiol 3-benzoate) injection on indices of immediate postexercise oxidative stress and antioxidant status were determined in adult male rats, with and without 8 weeks of prior dietary vitamin E deprivation. The treadmill running protocol (60 min at 21 m·min-1, 12% grade) induced significant oxidative stress as indicated by muscle glutathione status. Estrogen administration had little effect on postexercise tissue glutathione status, superoxide dismutase and glutathione peroxidase activity, and vitamin E levels. Estrogen administration induced significant reductions in muscle, liver, and heart vitamin C concentrations following exercise, as well as in unexercised male rats. Tissue vitamin C loss was not directly mediated through liver glycogen or glutathione status. Thus, estrogen administration generally did not appear to influence postexercise tissue indices of oxidative stress or antioxidant status and may have contributed to a decline in overall antioxidant protection by inducing losses in tissue vitamin C content.Key words: glutathione, vitamin E, muscle, superoxide dismutase, glutathione peroxidase.
