Background: Vernonia amygdalina, commonly known as bitter leaf, has been traditionally used for its potential antidiabetic properties. This study aimed to evaluate the therapeutic potential of Vernonia amygdalina extract (VAE) in ameliorating hyperglycemia using a streptozotocin (STZ) and high-fat diet (HFD)-induced rat model of diabetes. Methods: Sixty male Wistar rats were divided into six groups: normal control, diabetic control, and four treatment groups receiving different doses of VAE (100, 300, and 500 mg/kg body weight) orally for eight weeks. Diabetes was induced in rats by a single intraperitoneal injection of STZ (55 mg/kg) after four weeks of Nicotinamid feeding. Body weight, fasting blood glucose levels, HbA1c, serum insulin levels, superoxide dismutase (SOD) activity, and malondialdehyde (MDA) levels were measured. Results: Treatment with VAE significantly reduced fasting blood glucose levels in a dose-dependent manner compared to the diabetic control group (p \< 0.05). VAE administration also led to a significant decrease in HbA1c levels and an increase in serum insulin levels in a dosedependent manner (p \< 0.05). Furthermore, VAE supplementation restored SOD activity and reduced MDA levels, indicating improved antioxidant status in the treated groups (p \< 0.05). Conclusion: This study demonstrates the therapeutic potential of Vernonia amygdalina as an antidiabetic agent in the STZ and HFD-induced rat model of diabetes. VAE supplementation effectively reduced fasting blood glucose levels, improved glycemic control as indicated by reduced HbA1c levels, and enhanced insulin secretion. Moreover, VAE exhibited antioxidant activity by restoring SOD activity and reducing MDA levels. These findings suggest that Vernonia amygdalina could be a promising natural remedy for the management of diabetes. Further investigations are warranted to elucidate the underlying mechanisms and evaluate its long-term safety and efficacy in humans.

Background: Oxidative stress results from the amplification mechanism of COPD, which leads to decreased lung function and the quality of life of the sufferers. Vitamin D has a function in reducing oxidative stress levels through several mechanisms, which can be revealed by analyzing several biomarkers to determine the role of vitamin D on lung function and the quality of life of stable COPD patients. Methods: The subjects included GOLD 2 and 3 stable COPD patients who had 25(OH)D levels of \< 32 ng/ml and were receiving bronchodilator Indacaterol maleate therapy. The biomarkers examined included Nrf2, HDAC2, MDA, MMP-9, pulmonary function tests 6MWT, and QOL. The patients in the control and treatment groups were administered with vitamin D at a dose of 1,000 and 5,000 IU, respectively, for three months. Results: The administration of vitamin D to the patients in the control and treatment groups can significantly reduce oxidative stress, as evidenced by reduced MDA (p-value \< 0.01) and MMP-9 levels (p-value \< 0.01). Vitamin D affects exercise tolerance, as evidenced by 6MWT (p-value = 0.01). Vitamin D affects the quality of life, as evidenced by 6MWT (p-value = 0.01). Vitamin D affects Nrf2 levels (p-value = 0.08) and HDAC2 (p-value = 0.01). Conclusion: The pathway analysis through the study of the Nrf2, HDAC2, MMP-9, and MDA levels does not prove that vitamin D can prevent decreased lung function and quality of life in patients with stable COPD.

Background: Iron and folic acid deficiency during pregnancy can increase oxidative stress and result in impaired intra-uterine growth, abortion and preeclampsia. Folate is trace nutrient that influent for essential role for epigenetic mechanism cues into changes in gene expression and had impact health development. This study aimed to determine the effect of several doses of iron and folate supplementation on level of: MDA, glucose, creatinine, maternal body weight and number and birth weight of offspring. Methods: This research was conducted in the laboratory of the Center for Food and Nutrition Studies, Gadjah Mada University Yogyakarta. Experimental research with posttest only control group design with a number of samples: 20 pregnant rats, divided randomly into 4 groups. The control group (C) was given standard feed (AIN-93G), KI: added iron 1,8 mg/200gBW and folic acid 0,0023mg/200gBW, KII: added iron 3,6 mg/200gBB and folic acid 0,0045 mg/200gBW, KIII : added iron 5,4mg/200gBW and folic acid 0,0068 mg/200gBW. Duration of treatment 20 days. Measurement of body weight, blood pressure and then taken blood samples at the 21st day for examination of MDA, glucose, creatinine, erythrocyte level. Sectio caesarean to performed the number and body weight of offspring. Data obtained were analyzed using one way Anova followed by Post hoc LSD. Results: there are significant different (p \<0.001). on level of : MDA, glucose, creatinine, maternal body weight, average number and fetal weight of offspring between treatment group compare to control group. Conclusion: Iron and folate suplementation during pregnancy can decreased level of oxidative stress and better pregnant outcome.

Introduction: Niacin is part of the chemical structure of coenzymes nicotinamide adenine nucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Previous studies suggested that a high niacin intake could decrease the prevalence of cataracts, which may delay the onset of diabetic cataract. Aim: The aim of this study was to evaluate the effect of niacin on the hyperglycemia-induced osmotic stress and oxidative stress in human lens epithelial cells. Materials and Methods: Human lens epithelial cells were cultured in a high glucose condition. Oxidative stress markers, including malondialdehyde (MDA), protein carbonyl content (PCC) and glucose reactive protein (GRP), were measured using TBARS analysis (MDA) and ELISA (PCC and GRP) after 72 h incubation. Results: The MDA levels increased after high glucose administration relative to that in the control group (p \<0.05). Further, the groups that were co-treated with niacin showed decrease in the MDA levels for all doses of niacin and the lowest mean MDA level was obtained with 100 μM niacin. There was a decrease in the PCC levels for all doses, whereas the lowest mean PCC level was observed at a 100 μM niacin dose. The GRP levels increased after high glucose administration as compared with the control group. Also, the groups that were co-treated with niacin exhibited statistically significant reduction. Conclusion: These results suggest that niacin can inhibit the osmotic stress and oxidative stress which may lead to the progression of a diabetic cataract. Also, it may maintain lens transparency by acting as a precursor for glutathione biosynthesis and an antioxidant.

Background: Cadmium (Cd), is a toxic metal which affects various organs including testis. It produces oxidative stress leading to male infertility. Moringa tree, is a natural plant with a great therapeutic value and hence it is found to be effective both in prevention and treatment of various conditions including reducing toxicity of hazardous materials. The aim of the present study was to examine the effects of Pre-and Post-treatment with Moringa oliefera leaf extract (MoE) on testis in cadmium exposed rats. Materials and Methods: The present study was conducted at the Department of Physiology, Kasturba Medical College (KMC), Mangalore, Manipal University (MU), Karnataka, India, between (2011-2013). This prospective study consisted a total of 30 rats. These were divided into 5 groups with group I being the control. Data were presented as mean \±SD. student\’s t test was used as statistical tool, p\<0.05 considered statistically significant. Group IV and V were pre-and post-MoE treated groups respectively. Serum testosterone and tissue lipid peroxidation levels were estimated. Results: Treatment with MoE prior and after administration of cadmium, respectively showed an increase significantly in the testosterone levels and a decrease in the tissue lipid peroxidation as compared to the group treated with cadmium. However, the pre-treatment showed better results in combatting the toxic effects of cadmium. Conclusion: This study shows that Moringa olifera leaf extract altered the testosterone and tissue lipid peroxidation levels. Also, pre-treatment showed better outcome.
