Sodium metabisulfite (NaMBS) has been used as an antioxidant and antimicrobial agent in a variety of drugs and foods. The aim of our study was to evaluate the effect of subchronic ingestion of NaMBS on lipid peroxidation, protein and enzymatic antioxidants in the gastric tissue and splenic Wistar rat. The rats were divided into four groups (n = 06 rats/group) as follows; Control (C), rats treated with 0.25% NaMBS (S0.25%), rats treated with 1% NaMBS (S1%) and rats treated with 4% NaMBS (S4%). NaMBS was administered to animals via drinking water. At the end of the experimental period, Malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxi-dase (GPx), catalase (CAT) and thiols were determined. Redox status assess-ment revealed that 1% and 4% NaMBS doses induced gastric and spleen lipid peroxidation in animals compared to the control group. On the other hand, activities of SOD, GPx, CAT and thiols were reduced in the S1% and S4% groups in the stomach and spleen compared to the controls. Slight changes were detected in the GPx and CAT in the stomach of S0.25% group compared to the control group. In conclusion, the subchronic consumption of NaMBS has an adverse effect on the spleen and stomach by inducing oxidative damage leading to an increase in lipid peroxidation, protein oxidation and alteration of enzyme activity antioxidant.

The Impact

The main aim of the study was to evaluate the chemopreventive potential of Kayan Karpam (KK) against Benzo(a) Pyrene (B(a)P) induced lung carcinogenesis in experimental mice. In this study, we evaluated the impact of KK as an effective antioxidant and anticarcinogenic agent against B(a)P, a possible carcinogen present in cigarette smoke. All mice were randomly assorted into five groups. Group I mice served as control (Control), group II mice were received KK at the dosage of 250mg/kg b.wt. for 16 weeks. Groups III-VI received B(a)P at the dosage of 50mg/kg b.wt. weekly twice orally for the first 4 weeks. Further, along with B(a)P, group IV received KK, as like group 2 for 16 weeks, group V mice received B(a)P, as like groups 3 and 4, along with KK starting from the 9th week of the experimental period. We observed, that carcinogen induced mice treated with different treatment regimens of KK showed a potent chemopreventive action. Significant (P<0.05) increases in cellular enzymatic antioxidants such as SOD, CAT and GPx and levels of non-enzymatic antioxidants like GSH, vitamins E and C were noted in KK treated mice. Highly significant reductions were observed in the levels of lipid peroxidative by products and lung cancer marker enzymes like AHH, ᵧ-GT, 5’-ND and LDH in the mice administered with KK. Supplementation with KK to tumor bearing mice normalized the expression patterns of pro- and anti- apoptotic proteins (p21, Bax, Bcl-2), modulated NF-κB, and reduced the levels of COX-2. These findings further suggest the view that the Indian medicinal plants present in KK are promising sources of potential drugs against lung cancer.

Background: Sulfites are widely used as preservatives in the foods and pharmaceutical agents. It has been demonstrated that sulfites can react with a variety of cellular components and cause toxicity. Objective: The present study was designed to investigate the effects of ingested sodium metabisulfite (SMB) on serum antioxidant status in rats. Methods: Thirty-two male Wistar rats were randomly divided into control and treated groups. Treated groups received 10, 100, and 260 mg/kg body weight of SMB for 28 days. After 28 days, serum was assayed for measuring superoxide dismtase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), catalase (CAT) activities, glutathion (GSH) level and lipid peroxidation. Results: The results showed that the activities of GPx, GR, CAT and GSH levels were significantly decreased in 100 and 260 mg/kg SMB treated rats, while malondialdehyde (MDA) level was significantly increased in 260 mg/kg treated group when compared with the control group. Conclusion: It is concluded that SMB administration as dose-dependent is associated with decreased serum antioxidant enzyme activities and increased lipid peroxidation.

Purpose: To investigate the gastroprotective effect of leaf extract of Aloe barbadensis on ethanolinduced gastric ulcer in rats.Methods: Healthy male Wistar rats (n = 30) weighing 180 - 220 g (mean weight = 200 ± 20 g) were randomly assigned to 6 groups (5 rats/group): control group, gastric ulcer group, two Aloe barbadensis extract groups (250 and 500 mg/kg), cimetidine group and indomethacin group. Gastric ulcer was induced via oral injection of absolute ethanol at a dose of 1 mL/kg after a 24-h fast. Gross evaluation, determination of gastric juice acidity and histological examination of gastric tissue were carried out.Results: Treatment of gastric ulcer rats with Aloe barbadensis extract significantly reduced ulcerated area (UA), ulcer index (UI), and acidity of gastric juice (p < 0.05). Injection of 1 % carrageenan into rat hind paw led to a time-dependent increase in paw volume which peaked 3 h after injection. However, the Aloe barbadensis extract significantly and dose-dependently reduced the volume of inflamed paw, and inhibited edema formation (p < 0.05). It also markedly reduced or completely eliminated edema and leucocyte infiltration. Moreover, treatment of gastric ulcer rats with Aloe barbadensis leaf extract led to significant and dose-dependent reduction in gastric tissue MDA level (p < 0.05). Histological examination of the gastric wall showed that control rats had severe injury in gastric mucosa,accompanied by edema and leucocytes infiltration, relative to rats pretreated with extract which showed marked gastric protection and inhibition of edema and leucocytes infiltration. Moreover, the extract treatment protected the gastric surface against ulceration as indicated by reduced lesions in the treated rat model.Conclusion: These results show that Aloe barbadensis mitigates ethanol-induced gastric injury in rats via inhibition of lipid  peroxidation and inflammation. Thus, the extract has potentials for development into a therapeutic agent for the management of  gastric ulcer.

Makeup products contain heavy metals in variable amounts. Oxidative stress, damage, and aging could happen due to exposure to heavy metals. This study aimed to evaluate the concentrations of non-enzymatic antioxidants, and lipid peroxidation marker (malondialdehyde, MDA) in makeup and non-makeup users. 69 female students were sorted into two groups of 31 of non-makeup users (control group) and 38 of makeup users (case group). In this respect, the case group was also divided into 3 subgroups according to a period of 1.09±0.78 years (as mean±SD). 10 mL venous blood was drawn to determine the serum level of vitamin C, uric acid, glutathione (GSH) and MDA. The gained results were statistically analysed using SPSS. This in turn indicated a significant reduction in vitamin C, uric acid and GSH levels in makeup users compared to the control group. However, MDA concentrations were significantly higher in makeup users. A significant correlation between lipid peroxidation, dropping in non-enzymatic antioxidants and makeup products application was found.

To investigate the effect of Lippia multiflora (Verbanaceae) on the reproductive activity of male Wistar rats, three groups (A,B and C) of rats were treated with 400, 800 and 1600 mg/kg/day of Lippia multiflora leaves extract respectively for 28 days while 5ml/kg of distilled water was given to the control group D. At the end of the experimental period, animals were sacrificed and sperm characteristics, histology of the testes and epididymis were assessed. Lippia multiflora leaf extract caused a significant reduction (P<0.05) in sperm motility, a statistically significant dose dependent reduction in the sperm count and a significant (P<0.05) dose dependent increase in morphological abnormalities of the spermatozoa of the treated rats. Histopathological evaluation of the testis and epididymis revealed varying degrees of degeneration and necrosis of the germinal epithelia cell of the seminiferous tubules, spermiostasis and complete epididymal aspermia. Lippia multiflora leaf extract has significant anti-spermatogenic effects on adult male Wistar rats which could impair reproductive activities in these rats

Background: Many health problems are related to lifestyle and dietary factors. Since ancient times, food additives such as sulfites have been used to preserve foods. Diverse effects of sulfites on multiple organs have been reported but its effect on female reproductive organ has not been fully elucidated. The aim of this study was to investigate the effects of sodium metabisulfite (SMB) on ovarian tissue in adult rats. Methods: Four groups of female rats (n=32) were used. The experimental rats received 10, 100 and 260 mg/kg SMB for 28 days (S10, S100 and S260 groups, respectively). The control rats received distilled water for the same period. The ovarian volume, weight and the number of different types of follicles were estimated by stereological methods. Lipid peroxidation is assessed indirectly by the measurement of malondialdehyde (MDA), using the thiobarbituric acid (TBA) method. Results: The results showed a significant decrease in the ovarian volume, the number of primordial, primary, secondary, grafian follicles and corpus luteum in the SMB-treated animals compared with the control group (P < 0.05). In comparison to the control group, the number of atretic follicles increased in the SMB-treated rats. MDA was significantly increased in S260 group compared to the control group. Conclusion: The present data confirm sulfite-induced structural changes in the ovary. Increased level of MDA because of SMB ingestion suggests that free radicals may have a critical role in these changes.

Abstract. Physical exercise increases free radicals production; antioxidant supplementation may improve the muscle fiber’s ability to scavenge ROS and protect muscles against exercise-induced oxidative damage. This study was designed to examine the effects of all-trans resveratrol supplementation as an antioxidant to mediate anti-oxidation and lipid per-oxidation responses to exercise in male Wistar rats. Sixty-four male Wistar rats were randomly divided into four equal number (n = 16) including training + supplement (TS), training (T), supplement (S) and control (C) group. The rats in TS and S groups received a dose of 10 mg/kg resveratrol per day via gavage. The training groups ran on a rodent treadmill 5 times per week at the speed of 10 m/min for 10 min; the speed gradually increased to 30 m/min for 60 minutes at the end of 12th week. The acute phase of exercise protocol included a speed of 25 m/min set to an inclination of 10° to the exhaustion point. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) activity, non-enzymatic antioxidants bilirubin, uric acid, lipid peroxidation levels (MDA) and the total antioxidant capacity (TAC) were measured after the exercise termination. The data were analyzed by using one-way ANOVA. The result showed that endurance training caused a significant increase in MDA level [4.5 ± 0.75 (C group) vs. 5.9 ± 0.41 nmol/l (T group)] whereas it decreased the total antioxidant capacity [8.5 ± 1.35 (C group) vs. 7.1 ± 0.55 mmol/l (T group)] (p = 0.001). In addition, GPx and CAT decreased but not significantly (p > 0.05). The training and t-resveratrol supplementation had no significant effect on the acute response of all variables except MDA [4.3 ± 1.4 (C group) vs. 4.0 ± 0.90 nmol/l (TS group)] (p = 0.001) and TAC [8.5 ± 0.90 (C group) vs. 6.6 ± 0.80 mmol/l (TS group)] (p = 0.004). It was concluded that resveratrol supplementation may prevent exercise-induced oxidative stress by preventing lipid peroxidation.
