Glutathione is a thiol compound that plays an important role in the antioxidant defense system of the cell and its deficiency leads to an increased susceptibility to oxidative stress and, thus, progression of many disease states including head and neck cancer. In the present study, alterations of glutathione levels were investigated in study cohort of 500 samples (cohort 1 containing 200 head and neck cancer blood samples along with 200 healthy controls and cohort II with 50 head and neck squamous cell carcinoma tissue samples along with 50 control tissues) by high performance liquid chromatography. The results indicated that mean blood glutathione levels were significantly reduced in head and neck cancer patients (p<0.001) compared to respective controls. In contrast, the levels of glutathione total (p<0.05) and glutathione reduced (p<0.05) were significantly elevated in head and neck squamous cell carcinoma tissues compared to the adjacent cancer-free control tissues. In addition to this, pearson correlation performed to correlate different tissue glutathione levels (GSH) with clinical/pathological parameters demonstrated a significant negative correlation between pT-stage and GSH level ($r=-0.263^{**}$; p<0.01), C-stage and GSH level ($r=-0.335^{**}$; p<0.01), grade and GSH ($r=-0.329^{**}$; p<0.01) and grade versus redox index ($r=-0.213^{**}$; p<0.01) in HNSCC tissues. Our study suggests that dysregulation of glutathione levels in head and neck cancer has the potential to predict metastasis, and may serve as a prognostic marker.
Purpose: Both chronic periodontitis (CP) and iron deficiency anemia (IDA) induce oxidative stress in the body and cause an imbalance between reactive oxygen species and antioxidants, such as superoxide dismutase (SOD). This study explored the SOD enzyme activity of saliva and serum in CP patients with and without IDA and analyzed the impact of IDA on CP. Methods: A total of 82 patients were divided into four groups: control group (CG, 22), periodontally healthy IDA patients (IDA-PH, 20), CP patients (CP, 20), and IDA patients with CP (IDA-CP, 20). After clinical measurements and samplings, serum and salivary SOD levels were determined using an SOD assay kit. Results: IDA-CP patients exhibited a higher gingival index, bleeding on probing, probing pocket depth, and percentage (%) of sites with a clinical attachment loss (CAL) of ${\geq}6mm$ (P<0.008) than CP patients. The mean salivary and serum SOD levels were significantly lower in the IDA-PH, CP, and IDA-CP patients than in the CG group (P<0.008). A significant positive correlation between salivary and serum SOD activity was observed in IDA (P<0.05). Furthermore, serum and salivary SOD levels were significantly and negatively correlated with all periodontal parameters including the percentage of sites with CAL of 4-5 and ${\geq}6mm$ (P<0.05) except the significant correlation between salivary SOD activity and mean CAL and the percentage of sites with CAL of 4-5 mm (P>0.05) in these patients. Conclusions: Within the limits of this study, it may be suggested that IDA patients with chronic periodontitis have more periodontal breakdowns than patients with chronic periodontitis. Serum and salivary SOD activity levels were lower in the IDA-PH, CP and IDA-CP groups than in the CG. Iron deficiency anemia influenced the serum SOD activity but did not seem to affect the salivary SOD activity in these patients.

Objectives : Present study investigated the hepatoprotective effects and the optimal mixing ratio of fermented Schizandrae Fructus Pomace (fSFP) and Hoveniae Semen Cum Fructus (HSCF) extract combination in carbon tetrachloride (CCl4)-induced acute liver injury mice. Methods : ICR mice were orally administered with 200 mg/kg of fSFP, HSCF and mixtures of fSFP and HSCF [MSH (w:w); 1:1, 1:2, 1:4, 1:6, 2:1, 4:1, 6:1, and 8:1] for 7 consecutive days. Silymarin (100 mg/kg) was administered as a reference drug. 0.5 mL/kg of CCl4 was injected intraperitoneally to induce acute liver injury. Body weight gain, relative liver weight, serum chemistry, histopathological analysis, and hepatic endogenous antioxidants capacities were observed. Results : All diverse combinations of MSH significantly reduced relative liver weight increase by CCl4. In addition, MSH administrations significantly decreased the elevation of serum alanine aminotransferase and aspartate aminotransferase activities by CCl4. Histopathological observation indicated that all MSH treatments significantly reduced the increase of degenerated hepatocytes, inflammatory cell infiltration, and histological activity index score by CCl4. Moreover, all MSH administrations reduced the elevation of malondialdehyde contents, and ameliorated the reduction of hepatic glutathione contents, superoxide dismutase activity, and catalase activity. Among the various mixing ratio of MSH combinations, MSH 1:1 and 2:1 showed the most potent anti-oxidative stress, and hepatoprotective effect. Conclusion : Present results suggest that 1:1 and 2:1 combinations of MSH is promising herbal formulation with the hepatoprotective effect against oxidative stress.
Saline conditions invoke oxidative stress attributed to the overproduction of reactive oxygen species (ROS). Changes in quantum efficiency and antioxidative enzyme activity upon salt treatment were examined in a salt-tolerant plant, Atriplex gmelini, to test the hypothesis that salt tolerance of A. gmelini is due to the increased activity of antioxidative enzymes. A. gmelini showed optimum growth at 100 mM NaCl producing 116% of the shoot dry weight over control plants in 0 mM NaCl treatment. Healthy growth persisted up to 300 mM NaCl treatment maintaining normal internal water content and dry weight. No photochemical stress or damages on antioxidative defense system was obvious in plants of 2 and 4 day salt treatment which was indicated by increased quantum efficiency (Fv/Fm value), decreased stress index (Fo/Fm value), and increased activity of antioxidative enzymes such as SOD, APX, GR. However, the plants treated with 400 mM NaCl showed decrease in growth and in antioxidative enzyme activity although the enzyme activity was still higher than that of the 0 mM NaCl treated plants (l31%, 114%, and 134% of the SOD, APX, and GR activity, respectively). Interestingly, another important antioridative enzyme that scavenges H₂O₂ in plant cells, CAT, showed rapid decrease in its activity as salt concentration increased; 38%, 22%, 15% of the 0 mM NaCl treated plants at 200, 300, 400 mM NaCl treatments, respectively. It appears that the enzymes in ascorbate-glutathione cycle such as APX and GR play the major roles in scavenging ROS produced by salt stress in A. gmelini. After 6 days of salt treatment, the damage in photochemical and antioxidative defense system was indicated by decreased Fv/Fm value and increased Fo/Fm value. A. gmelini appears to cope with short term salt treatment by enhanced activity of the antioxidative defense system, whereas long term stress invoke oxidative stress by increased ROS due to the damages in photochemical and antioxidative system.

Purpose: Sprouts of evening primrose (Oenothera laciniata, OL) were reported to have high contents of flavonoids and potent antioxidant activity. This study examined the antioxidant and antiobesity activities of OL sprouts to determine if they could be a natural health-beneficial resource preventing obesity and oxidative stress. Methods: OL sprouts were extracted with 50% ethanol, evaporated, and lyophilized (OLE). The in vitro antioxidant activity of OLE was examined using four different tests. The antiobesity activity and in vivo antioxidant activity from OLE consumption were examined using high fat diet-induced obese (DIO) C57BL/6 mice. Results: The IC50 for the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging and superoxide dismutase (SOD)-like activities of OLE were 26.2 ㎍/mL and 327.6 ㎍/mL, respectively. OLE exhibited the ferric reducing antioxidant power (FRAP) activity of 56.7 ㎍ ascorbic acid eq./mL at 100 ㎍/mL, and an increased glutathione level by 65.1% at 200 ㎍/mL compared to the control in the hUC-MSC stem cells. In an animal study, oral treatment with 50 mg or 100 mg of OLE/kg body weight for 14 weeks reduced the body weight gain, visceral fat content, fat cell size, blood leptin, and triglyceride levels, as well as the atherogenic index compared to the high fat diet control group (HFC) (p < 0.05). The blood malondialdehyde (MDA) level and the catalase and SOD-1 activities in adipose tissue were reduced significantly by the OLE treatment compared to HFC as well (p < 0.05). In epididymal adipose tissue, the OLE treatment reduced the mRNA expression of leptin, PPAR-γ and FAS significantly (p < 0.05) compared to HFC while it increased adiponectin expression (p < 0.05). Conclusion: OLE consumption has potent antioxidant and antiobesity activities via the suppression of oxidative stress and lipogenesis in DIO mice. Therefore, OLE could be a good candidate as a natural resource to develop functional food products that prevent obesity and oxidative stress.
Antioxidants such as vitamin C and E may play a preventive role in the development of cancer and coronary heart disease. The status of vitamins C and E may be affected by lifestyle habits such as smoking , drinking, and exercise. These habits can modify the dietary requirements of vitamin C and vitamin E. the purpose of this study was to determine whether Korean young healthy men and women consume vitamins C and E in sufficient quantities relative to their lifestyle habits. Among the participants in this study, 52% of the men and none of the women were smokers. ; 84% of all subjects drank alcohol more than once a week ; and the men exercised more often than the women. The concentrations of serum total , HDL-, and LDL- cholesterol were higher in the women than in the men, but the serum triglyceride concentrations were higher in the men than in the women. The men consumed less satuated fat than the women (p<0.05) . The daily intakes of vitamin C for the men and the women were 47.1mg and 65.6mg, respectively. On the other hand , the daily vitamin E intake was higher in the men (11.8mg) than women(6.9mg). The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and in no subjects were they below the minimum value of ranges. However, about 19% of male subjects and 10% of female subjects showed deficient status, although the mean serum vitamin C levels were normal . Lifestyle habits fo the sort mentioned above have little influence on the serum vitamin C and $\alpha$-tocopherol concentrations. The serum $\alpha$-tocopherol concentration had a positive correlation with total fat and alcohol consumption. The serum vitamin C concentration was positively associated with regular exercise, but it was negatively correlated with the number of cigarettes smoked. Meanwhile, the serum lipid persoxide concentration , the indirect index of oxidative stress, was influenced by certain variable such as body mass index , the number of cigarettes smoked , alcohol consumption, energy expenditure, vitamin C intake, and serum ${\gamma}$-tocopherol concentration. Serum lipid peroxide concentration was positively associated with body mass index, the number of cigarette smoked , serum triglyceride , and HDL-cholesterol concentration. In conclusion , the vitamin E requirements of the subjects were met by the Recommended Daily Allowance (RDA) regardless of lifestyle habits. However, serum vitamin C concentrations showed individual variation and was below the normal ranges. Smoking and exercise influenced serum vitamin C concentration. Therefore, a reevaluation of the requirements of vitamin C relative to lifestyle habits is necessary.
This study was performed to examine the combined effects of gamma linolenic acid and isoflavone supplementation on menopausal symptoms and serum lipids in 73 postmenopausal women. A total subjects were randomly assigned to isoflavone (30 mg) + gamma-linolenic acid (110 mg) group or placebo group. We measured menopausal symptoms by modified Kupperman Index (KI) and oxidized LDL, lipid peroxides, blood components and anthropometric parameters before and after the 12 week intervention period. After the 12 weeks of supplementation, supplement group and placebo group showed a significant reduction of modified kupperman index (p < 0.001). Isoflavone (30 mg) + gamma-linolenic acid (110 mg) supplement group showed a significant reduction of oxidized LDL cholesterol concentration (p = 0.006) whereas placebo group did not show significant change. Isoflavone and gamma-linolenic acid consumption did not significantly affect plasma concentrations of total, LDL, HDL cholesterol, triglyceride, apo A1, B and blood components. The result of present study demonstrated the supplementation of 30 mg isoflavone and 110 mg gamma-linolenic acid per day for 12 weeks may protect LDL cholesterol from oxidative stress.
This study examines the relationship between urinary arsenic concentration and urinary 8-hydroxydeoxyguanosine (8-OHdG) concentrations, an index of oxidative DNA damage, among women who live near abandoned metal mines. The sample consisted of 165 residents living near two abandoned metal mines located in Chungbuk Province. Demographic characteristics as well as environmental factors relevant to arsenic exposure were collected through interviews, and urinary arsenic concentrations and urinary 8-OHdG concentrations of the research subjects were measured. The collected data were subsequently analyzed using the statistics program SPSS 12.0. The geometric average of urinary arsenic concentrations among the research subjects was $5.65\;{\mu}g/g$ creatinine. In a correlation analysis between urinary arsenic and 8-OHdG concentrations, the correlation coefficient was significant (p<0.001) at 0.399. This study suggests that urinary 8-OHdG concentrations may be a DNA damage marker for chronic arsenic exposure in women.
The present study was undertaken to analyze the status of erythrocytic malonyl dialdehyde (MDA) as an index of lipid peroxidation in normal cycling and ${\alpha}$-tocopherol supplemented anestrus buffalo heifers. Before supplementation, the blood samples were collected at weekly interval in anestrus and normal cycling buffalo heifers and data from four samples was pooled to establish pre-supplementation base line. Thereafter, the blood samples from anestrus and ${\alpha}$-tocopherol supplemented anestrus buffalo heifers were taken at fortnightly interval for 12 weeks during supplementation and for four weeks during the post-supplementation period. The pre-supplementation endogenous erythrocytic MDA, 0.3% $H_2O_2$ induced-erythrocytic MDA and 1.5% $H_2O_2$ induced-erythrocytic MDA levels (nmol/g Hb) increased significantly (p<0.05) in anestrus heifers ($372.3{\pm}5.0$, $564.4{\pm}5.7$, $862.4{\pm}8.5$) when compared to normal cycling animals ($289.6{\pm}3.0$, $508.2{\pm}6.0$, $777.7{\pm}4.9$). Oral supplementation of 3,000 mg of ${\alpha}$-tocopherol per week per animal in anestrus heifers resulted in a progressive and significant (p<0.01) decline in erythrocytic MDA levels. These observations implied that supplementation of ${\alpha}$-tocopherol to anestrus buffalo heifers ameliorated their antioxidant status by alleviating the effects of oxidative stress.
Effects of oral taurine supplementation (6g/day)for 2-4 weeks on activities of red blood cell(RBC)total superoxide dismutase (SOD) and plasma glutathione peroxidase(GSH-Px) and the level of malondialdehyde(MDA) were evaluated in healthy female adults (23.6$\pm$0.3 years old). Compared to the value for 0 week plasma GSH-Px activity of the subjects was significantly lower after 2 weeks of taurine supplementation(p<0.05) and recovered to the value similar to 0 week after 4 weeks of taurine supplementation. RBC total SOD activity tended to be decreased after 2 weeks of taurine supplmentation compared to the values for 0 week although the difference between the means of the two group was not statistically significant. Plasma MDA level was not significantly decreased by taurine supplementation most probably due to the fact that the subjects participated in the present study were healthy and their antioxidant defense system had been in the 'normal' range. Plasma MDA concentration was negatively correlated with plasma taurine concentration(r=-0.2003m p<0.05) but tended to be positively correlated with plasma cholesterol concentration(r=0.2465, p=0.0645) as expected Plasma GSH-Px activity was positively associated with the percentage of 22:0 (r=0.2892, p<0.05) or 20:4w6(r=0.2939, p<0.05). On the other hand plasma MDA concentration was positively correlated with the percentage of 20:5w3 in plasma total lipids(r=0.2635 p<0.05) and negatively correlated with $\Delta$5 desaturation index of w6 fatty acids(20:3w6⇒20:4w6) in plamsa total lipids(r=-0.2714, p<0.05) as well as in phospholipids(r=-0.2864, p<0.05). From these results protective effect of taurine supplementation against lipid peroxidation and antioxidant defense system in humans appears to be minimal when the subjects are in a relatively healthy state. Further studies concerning the antioxidant efficacy of taurine should be conducted in human subjects under various disease states related to oxidative stress such as diabetes and artheroxclerosis.
