To evaluate the effects of supplementing diets with carotenoid and ascorbic acid (AsA) on the antioxidative ability of Osteogenic Disorder-Shionogi (ODS) rats, we added synthetic b-carotene (bC), AsA, and powders of persimmon (Ka) and pods (Po) containing bC and AsA to the diet and obtained the following results. The urinary 8-hydroxydeoxyguanosine (8-OHdG) concentration was low in the –betaC•AsA and +AsA groups but high in the +betaC. AsA, +Ka, and +Po groups. The thiobarbituric acid-reactive substances (TBARS) in both the liver and skin were higher in the –betaC•AsA group than in the +betaC•AsA group and were low in the +Ka and +Po groups. As antioxidant enzymes, glutathione peroxidase (GSH-Px) activity was high in the +betaC•AsA group, low in the –betaC•AsA group in both the skin and liver, and also high in the + Ka and +Po group in the liver. Superoxide dismutase (SOD) activity was high in the –betaC•AsA group and low in the +betaC•AsA and +Ka groups in both the skin and liver. Catalase (CAT) activity in the liver was low in the –betaC•AsA, + AsA, and +betaC groups and high in the +betaC•AsA and + Po groups. These results confirmed that the administration of betaC, AsA, and persimmons and pods increases antioxidative ability in the skin and liver of ultraviolet-b(UV-B)-irradiated ODS rats.

Cisplatin (CDDP), an anticancer drug, induces remarkable toxicity in the kidneys of animals and humans and it has been well documented that reactive oxygen species and the renal antioxidant system are strongly involved in acute renal damage induced by CDDP. The aim of the present study was to investigate whether or not the renal antioxidant system plays also an important role in chronic renal damage induced by repeated doses of CDDP (1 mg/kg intraperitoneally twice weekly during 10 weeks in rats). In order to elucidate it, serum creatinine and urea levels, renal glutathione and thiobarbituric acid-reactive substances (TBARS) content, as well as renal superoxide dismutase and glutathione peroxidase activities were measured in the kidney homogenates of chronically CDDP-treated rats and additionally histological studies were performed in the rat kidneys. The chronic treatment with CDDP induced a significant increase in creatinine and urea levels in serum, but the other parameters mentioned above were not significantly modified as compared to the values in nontreated rats. Taking into account these results, we conclude that chronic CDDP administration induces also severe nephrotoxicity, in contrast to CDDP acute application, without any significant modification in the activity of relevant antioxidant enzymes such as superoxide dismutase and glutathione peroxidase, renal glutathione and lipid peroxides, by which the role of the antioxidant system in chronic nephrotoxicity induced by CDDP in rats is uncertain.

Purpose The purpose of this study is to determine the effect of olive cake (CO) on glycaemia and lipemia and lipid peroxidation and antioxidant enzymes activities in erythrocytes and tissues, in streptozotocin (STZ)-induced diabetic rats. Design/methodology/approach Diabetes was induced by a single intraperitoneal injection of STZ (55 mg/kg BW). In total, 12 diabetic D rats, weighing 260 ± 20 g, were divided into two groups fed a casein diet supplemented (D-OC) or not (D) with OC (7.5 per cent), for four weeks. Findings In D-OC compared with D, glycaemia, total cholesterol and triglycerides values (−40 per cent; p = 0.007, 27 per cent; p = 0.007 and −27 per cent; p = 0.0019). In erythrocyte, liver, kidney, heart, muscle and brain, thiobarbituric acid reactive substances contents were respectively, (−19 per cent; p = 0.03, −32 per cent; p = 0.002, −20 per cent; p = 0.04, −68 per cent; p = 0.003, −74 per cent; p = 0.0003 and −38 per cent; p = 0.04). In erythrocyte, SOD, GSH-Px and CAT activities were respectively, (+14 per cent; p = 0.01, +74 per cent; p = 0.012 and +34 per cent; p = 0.0009). In the liver, kidney, heart and muscle, SOD activity was respectively, (+31 per cent; p = 0.004, +12 per cent; p = 0.038, +43 per cent; p = 0.001 and +23 per cent; p = 0.18). GSH-Px activity was respectively, (+121 per cent; p = 0.0009, 89 per cent; p = 0.0006, + 95 per cent; p = 0.008, +71 per cent; p = 0.02 and +26 per cent; p = 0.01), in the liver, kidney, heart, muscle and brain. Catalase activity was (+21 per cent; p = 0.008) in the liver, (+88 per cent; p = 0.0002 in the kidney, +53 per cent; p = 0,002 in the heart and 83 per cent; p = 0.00004 in the muscle). Originality/value In diabetic rats, OC reduces hyperglycaemia induced by STZ and attenuates triglyceridemia and cholesterolemia. This residue is able to decrease the oxidative stress by increasing the antioxidant enzymes activity in erythrocytes and tissues. The high contents of phytoconstituents present in OC are considered to be responsible for this effect.

Abstract We studied the biological variability of blood superoxide dismutase (SOD; EC 1.15.1.1), glutathione peroxidase (GPX; EC 1.11.1.9), and catalase (CAT; EC 1.11.1.6) in a sample of 1836 apparently health subjects, ages 4-97 years. SOD and GPX activities were assayed in plasma (P) and erythrocytes (E) by automated methods, and CAT was measured in erythrocytes by a manual technique. No statistically significant variation of these antioxidant enzyme activities according to gender was demonstrated, except for E-GPX, which was slightly but significantly higher in women than in men (P less than 0.001). Activities appear rather stable in adults less than 65 years old, but decrease for most enzymes in the elderly. There is no evidence that weight, blood pressure, or menopause influences the antioxidant enzymes' activities. In girls ages 10-14 years, E-SOD activity is reduced by 16% (P less than 0.05) after menarche. Variations related to smoking and alcohol consumption are slight and concern only P-SOD and P-GPX, respectively. Conversely, intake of some drugs (e.g., anti-inflammatory agents, antidepressants, and thyroid hormones) modifies activity of some of the three enzymes. E-SOD positively correlates with P-SOD (r = 0.216, P less than 0.001) and E-CAT (r = 0.123, P less than 0.001), and E-GPX with P-GPX (r = 0.218, P less than 0.001). Finally, we propose reference intervals for activities of the three antioxidant enzymes in blood in individuals less than 65 years old.

Activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px) and glutathione reductase (GSSG-R) and concentration of ascorbate, alpha-tocopherol, non-protein and protein-bound sulfhydryl compounds and thiobarbituric acid-reactive substances (TBA-rs) were measured in liver and serum of rats 6, 12 and 24 h and 2, 5 and 7 days after intoxication with 1.5 g or 3.0 g methanol/kg b.w. Liver GSH-Px and GSSG-R activities and SH-groups and ascorbate content were significantly diminished at 6 and 24 h, while TBA-rs were increased. Serum SOD, GSH-Px and GSSG-R activities and SH-groups concentration were reduced while TBA-rs were elevated. The changes were more intensive after application of the higher dose of methanol. It is concluded that methanol impairs the liver and blood serum antioxidant mechanisms in rats.

The study aimed to evaluate the effect of 14-day vacuum aging on the volatile compounds (VOC) profile, oxidative profile, antioxidant enzymes activity, and sensory evaluation in the Longissimusthoracis muscle of foal meat under vacuum aging. Longissimusthoracis (LT) was sampled in 20 mm thick slices, vacuum packed, and stored at 4 °C. Samples were randomly assigned to different aging times (1, 6, 9, 14 days after slaughtering). VOCs, thiobarbituric acid reactive substances (TBARs), hydroperoxides, carbonyl proteins, superoxide dismutase, catalase, and glutathione peroxidase were analyzed, and a sensory test was performed. A nested one-way analysis of variance (ANOVA) was performed for aging time as an independent variable. Significance was set at p < 0.05. The main VOCs originating from cooked steaks were aldehydes, (from 47.18% to 58.81% of the total volatile compounds), followed by hydrocarbons (from 9.32% and 31.99%). TBARs and hydroperoxides did not show variations due to aging (p > 0.05), instead, protein carbonyls showed higher values at the 14th day (p < 0.01). Catalase, superoxide dismutase, and glutathione peroxidase showed increasing values during aging time (p < 0.01). Vacuum aging slowed down lipid oxidation, and protein oxidation was shown to be present. However, the best vacuum aging duration is in the range of 6–9 days from slaughtering, with an improvement of sensory evaluation.

Сeftriaxone administration for 14 days (300 mg/kg, i.m.) increased level of thiobarbituric acid reactive substances and decreased the activity of superoxide dismutase and catalase antioxidant enzymes in the colon mucosa of rats immediately after antibiotics injection. On the 29th day of the experiment (in 14 days after ceftriaxone withdrawal) the level of TBA-active substances still 2.5-fold (P <0.05) exceeded the control value and SOD activity remained below control values to the 72nd day of the experiment. These were accompanied by decreased level of protein thiol groups in 15 and 29 days 1.9-fold (P <0.05) and 1.4-fold (P = 0.08), respectively. Thus antibiotics can lead to long-term oxidative disturbance in the colon mucosa of rats.

OBJECTIVE: The neurotrophins, antioxidant enzymes and oxidative markers have reciprocal interactions. This report verified in chronically stable medicated schizophrenic patients whether there are correlations between the serum levels of superoxide dismutase, a key enzyme in the antioxidant defense, thiobarbituric acid reactive substances, a direct index of lipid peroxidation, and brain-derived neurotrophic factor, the most widely distributed neurotrophin. METHOD: Sixty DSM-IV schizophrenic patients were included (43 males, 17 females). Mean age was 34.7 ± 10.8 years, mean age at first episode was 19.8 ± 7.9 years, and mean illness duration was 14.9 ± 8.5 years. Each subject had a blood sample collected for the determination of serum levels of brain-derived neurotrophic factor, thiobarbituric acid reactive substances and superoxide dismutase. RESULTS: Brain-derived neurotrophic factor levels showed a positive correlation with thiobarbituric acid reactive substances levels (r = 0.333, p = 0.009). Brain-derived neurotrophic factor levels were not correlated with superoxide dismutase levels (r = - 0.181, p = 0.166), and superoxide dismutase levels were not correlated with thiobarbituric acid reactive substances levels (r = 0.141, p = 0.284). CONCLUSIONS: The positive correlation between brain-derived neurotrophic factor and thiobarbituric acid reactive substances suggests the need of further investigation on intracellular interactions of neurotrophins, antioxidant enzymes and oxidative markers. In addition, this opens a venue for investigation on treatments for the prevention of neurotoxicity along the course of schizophrenia.
