Background: Cigarette smoke free radicals can cause cellular damage and different diseases. All the body fluids have antioxidants which protect against free radicals. Objective: The aim of this study was to evaluate salivary total antioxidant capacity and peroxidase, uric acid and malondialdehyde levels in smokers and a nonsmoking control group. Methods: Unstimulated saliva was collected from 510 males. A total of 259 subjects were current smokers and 251 were non-smokers. The levels of salivary total antioxidant capacity, uric acid, peroxidase and malondialdehyde were measured using standard procedures. Data were analyzed with t test and ANOVA. Results: The smokers were younger and dental hygiene index was higher than healthy nonsmoking controls. The mean total antioxidant capacity in smokers and nonsmokers was 0.13±0.07 and 0.21±011, respectively (P=0.001). Smokers had significantly lower peroxidase and uric acid levels than healthy controls. In addition, the mean malondialdehyde levels in the smokers and nonsmokers were 4.55 ±2.61 and 2.79 ±2.21, respectively (P=0.001). Conclusion: Cigarette smoke produces free radical and oxidative stress, causing many side effects. Salivary antioxidant levels decreased and malondialdehyde levels increased in smokers, indicating the high oxidative stress among smokers compared to nonsmokers. Cigarette smoke had deleterious effects on main salivary antioxidants levels.

Background: Over the past few years, the benefits of co-administration of omega-3 and antioxidants have been reported in the management of non-alcoholic fatty liver disease (NAFLD) complications.This study evaluated the effects of Camelina sativa oil (CSO) supplementation as one of the richest dietary sources of omega-3 fatty acids on glucose homeostasis,inflammation, metabolic endotoxemia, and oxidative stress in NAFLD patients. Methods: In all, 43 subjects with NAFLD were allocated to either an intervention (20g/d CSO) or placebo (20g/d sunflower oil) group receiving a calorie-restricted diet for 12 weeks. Fasting serum levels of glycemic indices, hs-CRP, endotoxin, antioxidant enzymes activity, total antioxidant capacity (TAC), malondialdehyde (MDA), 8-iso-prostaglandin F2α (8-iso-PGF2α), and uric acid were measured at baseline and post-intervention. Results: CSO intake led to a significant decrease in insulin concentration (-17.49%), homeostasis model assessment of insulin resistance (HOMA-IR) (-20%), high-sensitive C-reactive protein (hs-CRP), (-12.94%), lipopolysaccharide endotoxin (-32.55%), malondialdehyde (MDA) (-18.75%), 8-iso-prostaglandin F2α (8-iso-PGF2α) (-19.55%) and a significant increase in the levels of total antioxidant capacity (TAC) (31.82%) and superoxide dismutase activity (10.22%) in the CSO group compared with the placebo group. Also, there was no significant difference between the two groups in fasting plasma glucose, quantitative insulin sensitivity check index (QUICKI), catalase, glutathione peroxidase activity, and uric acid level. In addition, within-group analyses showed a significant reduction of insulin, QUICKI, hs-CRP, and endotoxin levels in the intervention group. Conclusion: These findings indicate that CSO may improve glycemic, inflammation, metabolic endotoxima, oxidative stress status, and mental health in patients with NAFLD.

Background: Smoking habits enhance free radical in the body, which oxidize lipids to form malondialdehyde. One group that is vulnerable to smoking is adolescents. Red dragon fruit and red guava have the possibility as functional foods due to their vitamin and phytochemical content, which have antioxidant effects. This is an opportunity to prevent oxidative stress among adolescent smokers.Objectives: This study aimed to analyze the effect of red dragon fruit, red guava, and its combination to total antioxidant capacity (TAC) and malondialdehyde (MDA) levels among adolescent mild smokers.Methods: This research was an experimental study with a randomized pre-test and post-test control group design. Forty-eight subjects of male adolescent aged 16-17 years with mild smoking habits were divided into four groups: the control group (K), the intervention group with 200 grams of red dragon fruit (P1), 200 grams of red guava (P2), and the combination of both (100 grams red dragon fruit + 100 grams red guava) (P3), for 14 days. TAC examination used the DPPH method and MDA levels using the TBARS method were measured before and after the intervention.Results: After 14 days of intervention, the mean TAC was changed by -0,10±0,76 in the K group, 0,97±1,62 in the P1 group, 0,74±1,39 in the P2 group, and 0,74±1,29 in the P3 group. But the changes of TAC in all intervention groups were not significantly different from the control group (p>0,05). The mean MDA level changed by 0,229±0,371 in the K group, decreased by -0,654±0,922 in the P1 group, -0,592±0,818 in the P2 group, and -1,166±0,670 in the P3 group. The mean difference of the MDA level in all intervention groups was significantly different from the control group (p<0,05).Conclusion: Consumption of red dragon fruit, red guava, or a combination of red dragon fruit and red guava can reduce malondialdehyde levels significantly among male adolescent mild smokers. Whereas the total antioxidant capacity was changed but not significant.

Background: The total antioxidant capacity of plasma of preterm infants has been suggested to be lower than that of term infants. The objective of this study was to compare the total antioxidant capacity of the breast milk of mothers who delivered prematurely with that of mothers who delivered at term. Materials and Methods: A total of 71 breast milk samples were collected, 41 from mothers who delivered preterm (27 to 37 weeks) and 30 from mothers who delivered at term (38 to 42 weeks). Results: The mean total antioxidant capacity of the breast milk of mothers who delivered prematurely was higher (2.19 ± 0.88 mmol/L) than that of mothers who delivered at term (1.7 ± 0.86 mmol/L) (p = 0.024). Conclusion: Breastfeeding may protect preterm infants against oxidative stress and related disorders in the neonatal period.

Background: The free radical theory of aging postulates that aging results from the accumulation of deleterious effects caused by free radicals, and the ability of an organism to cope with cellular damage induced by ROS plays an important role in determining organismal lifespan. GSH and SOD functions by donating the proton and in scavenging the superoxide radicals, thereby protecting the body against oxidative stress by scavenging the free radicals produced in the body. Glutathione peroxidase also have similar function, it reduce lipid hydroperoxides to their corresponding alcohols and free hydrogen peroxide to water.Methods: Hundred healthy adults from staff and student community under the age group of 20 to 60 years were recruited. Approximately 5ml blood sample was collected and used for the analysis of lipid profile, MDA and antioxidant status using standard protocol.Results: The lipid profile, MDA and antioxidant status were measured and compared with that of serum nitric oxide levels of 100 healthy individuals of the age 20-60 yrs. Men aged 20-29 years showed significantly higher NO levels compared to corresponding women. There is a significant reduction in total antioxidant capacity in elderly people. With the decrease in NO there is increase in MDA is observed.Conclusions: There is a significant reduction in total antioxidant capacity in elderly people. This reduction in antioxidant capacity implies a defect in antioxidant system, may be due to a reduction in individual antioxidant or may be caused by a non-equilibrium or poor cooperation between them.

Health professionals exposed to anesthetic gases are at higher risk of reproductive, neurological, hematological, immunological, hepatic and renal system diseases. We investigated if oxidative stress induced by chronic exposure to anesthetic gases has any association with this matter. Plasma lipid peroxidation, total antioxidant capacity and total thiol molecule levels were measured in 66 operating room staff in comparison with 66 controls. The exposed group had a significantly higher level of lipid peroxidation with decreased thiol groups compared to control subjects. Total antioxidant capacity of the body was no different among exposed and not exposed subjects. Increased lipid peroxidation in the blood of exposed subjects warns that oxygen free radicals have increased in the body and thus might attack cells, which, in the longterm, results in multi-organ damage. The remaining blood total antioxidant capacity at normal values is promising and means that other non-thiol antioxidants, such as uric acid, transferrin, ceruloplasmin, albumin, and vitamin antioxidants, such as a-tocopherol and ascorbic acid, have been stimulated to maintain the total anti-oxidant power of the body at normal state.

AbstractIntroduction:The study aimed at evaluating oxidative stress using malondialdehyde (MDA), total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) markers in sheep naturally infected withPsoroptes ovis(Acari).Material and Methods:The study was performed on 40 sheep divided into two equal groups: a healthy group (group I) and a group naturally infected withPsoroptes ovis(group II). The sera were obtained by centrifuging blood samples collected from the vena jugularis and serum MDA level changes in the samples were measured spectrophotometrically. Commercially available test kits were used for the measurement of TAC and TOS levels. The percentage ratio of TOS level to TAC level was accepted as OSI.Results:The serum malondialdehyde, total oxidant status levels, and oxidative stress index increased significantly (P < 0.01) in group II, while the serum total antioxidant capacity levels decreased significantly (P < 0.01) in this group. Negative correlations between total antioxidant capacity and total oxidant status and total antioxidant capacity and malondialdehyde, and a positive correlation between total oxidant status and malondialdehyde were found in infected sheep.Conclusion:The obtained results indicated the relationship between oxidant/antioxidant imbalance andPsoroptes ovisinfection in sheep. Their MDA, TAC, TOS, and OSI markers may be used to determine the oxidative stress in natural infections withPsoroptes ovis.
