Obesity and high-fat diet (HF) are prevalent causes of oxidative stress (OS). Duodenal-jejunal omega switch (DJOS) is a bariatric procedure used for body mass reduction, extensively tested in animal models. We studied the long-term impact of bariatric surgery and an HF diet on the oxidative stress markers in erythrocytes and heart muscles of rats. We analyzed superoxide dismutase (SOD), catalase (CAT), glutathione transferase (GST), glutathione reductase (GR), glutathione peroxidase (GPx) activity and malondialdehyde (MDA) concentration in DJOS or SHAM (control) operated rats fed with different dietary protocols (control diet (CD) and high-fat diet (HF)), before and after the surgery (CD/CD, HF/HF, CD/HF, and HF/CD). We observed higher erythrocytes CAT, GST and GPx activity in DJOS-operated (vs. SHAM) rats fed with an HF/HF diet. For DJOS-operated rats, erythrocytes CAT and GPx activity and MDA concentration were significantly lower in CD/CD group. We observed increased heart muscle GR activity in SHAM-operated rats (vs. DJOS bariatric surgery) fed with an HF/HF diet. Change from HF to CD diet increased heart muscle GPx activity after DJOS bariatric surgery. Heart muscle SOD activity was lower in HF/HF and CD/CD groups after DJOS bariatric surgery (vs. SHAM). DJOS surgery significantly reduced heart muscle MDA concentration in HF/HF and HF/CD groups (vs. SHAM). We conclude that the selected dietary patterns had a stronger impact on oxidative stress markers in erythrocytes and heart muscle than DJOS bariatric surgery.

The medicinal plantsArtemisia iwayomogi(A. iwayomogi) andCurcuma longa(C. longa) radix have been used to treat metabolic abnormalities in traditional Korean medicine and traditional Chinese medicine (TKM and TCM). In this study we evaluated the effect of the water extract of a mixture ofA. iwayomogiandC. longa(ACE) on high-fat diet-induced metabolic syndrome in a mouse model. Four groups of C57BL/6N male mice (except for the naive group) were fed a high-fat diet freely for 10 weeks. Among these, three groups (except the control group) were administered a high-fat diet supplemented with ACE (100 or 200 mg/kg) or curcumin (50 mg/kg). Body weight, accumulation of adipose tissues in abdomen and size of adipocytes, serum lipid profiles, hepatic steatosis, and oxidative stress markers were analyzed. ACE significantly reduced the body and peritoneal adipose tissue weights, serum lipid profiles (total cholesterol and triglycerides), glucose levels, hepatic lipid accumulation, and oxidative stress markers. ACE normalized lipid synthesis-associated gene expressions (peroxisome proliferator-activated receptor gamma, PPARγ; fatty acid synthase, FAS; sterol regulatory element-binding transcription factor-1c, SREBP-1c; and peroxisome proliferator-activated receptor alpha, PPARα). The results from this study suggest that ACE has the pharmaceutical potential reducing the metabolic abnormalities in an animal model.

Obesity is associated with renal lipomatosis, inflammation and oxidative stress. Vitamin E is a liposoluble antioxidant vitamin and PLGA (polylactic-CO-glycolic acid) nanoparticles (NPs) represent a delivery carrier of this vitamin to the abdominal viscera. The aim of this study is to evaluate the renal and systemic effects of PLGA- NPs loaded with vitamin E in high fat diet Wistar rats. Young heathy Wistar male rats (3months old, n=20) were fed for 4 weeks either with standard diet or with high caloric/fat diet. These two experimental groups were divided in two subgroups and for the following 21 days, one group received PLGA-NPs loaded with vitamin E (1 mg/kg) body and the other didn�t. Metabolic serum parameters, oxidative stress markers ( malondialdehyde, MDA and total thiols) from kidney homogenates were measured by spectrophotometric methods. Hematoxylin-eosin stain histopathologic examination of kidneys was performed. The obesogenic diet increased the serum levels for triglycerides (p[0.001) and renal function markers: urea (p[0.02), creatinine (p[0.02) and cystatin (p[0.01). The treatment reduced the kidney inflammation, prevented tubulonephrosis damage and improved the renal oxidative stress markers (p[0.05) in the high fat diet group. In conclusion, PLGA-NPs loaded with vitamin E had renoprotective effect in high fat diet Wistar rats.

Purpose: This study was aimed to evaluate the antioxidant and anti-inflammatory effects of vitamin D and Simvastatin (SIM) on a high-fat diet (HFD) induced-obese rats. Methods: 40 adult male rats were divided into four groups: control group, HFD, HFD + vitamin D, and HFD + SIM for 14 weeks. Vitamin D or SIM supplementation was done for the last 6 weeks. Vitamin D dosage was 500 IU/kg, while SIM dosage was 10 mg/kg. Interleukin-6 (IL-6) concentration and markers of oxidative stress including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione(GSH) concentrations in serum were determined using ELISA kits and spectrophotometry methods, respectively. Results: Treatment with vitamin D or SIM could significantly reduce IL-6 and MDA and increases SOD, GPx activities, and GSH levels. Oxidative stress can result not only from increased ROS production but also from dysfunctional antioxidant defenses. Conclusion: From the experimental results, it was observed that SIM and vitamin D could attenuate oxidative stress and inflammation markers associated with obesity.
