Brazil nut (Bertholletia excelsa) and metformin abrogate cardiac complication in fructose/STZ-induced type 2 diabetic rats by attenuating oxidative stress and modulating the MAPK-mTOR/NFkB/IL-10 signaling pathways.
Background: The global prevalence of diabetic heart complication has been on the increase, and some of the drugs that are currently used to treat diabetes mellitus (DM) have not been able to mitigate this complication.
Objective: This study determines the effect of Brazil nut (Bertholletia excelsa) and metformin on diabetic cardiomyopathy (DCM) in fructose/streptozotocin (STZ)-induced type 2 diabetic rats and also characterizes using Gas Chromatography Mass Spectrophotometry and Fourier Transform Infrared the bioactive compounds in 50% aqueous ethanol extract of Brazil nut.
Design: After inducing type 2 DM, 30 male albino Wistar rats were separated into five groups that comprised of six rats per group, and they were treated as follows: groups 1 (Control) and 2 (Diabetic control) rats received rat pellets and distilled water; group 3 (Diabetic + Brazil nut) received rat pellets and Brazil nut extract (100 mg/kg, orally) dissolved in distilled water, group 4 (Diabetic + metformin) received metformin (100 mg/kg, orally) dissolved in distilled water, while group 5 (Diabetic + Brazil nut + metformin) received oral administrations of Brazil nut (100 mg/kg) and metformin (100 mg/kg) dissolved in distilled water. This study lasted for 6 weeks. The dose of Brazil nut used was selected from our pilot study on the minimum therapeutic dose of different concentrations of Brazil nut extract.
Results: STZ administration induced insulin resistance, hyperglycemia, loss of weight, dyslipidemia, oxidative stress, inflammation, apoptosis, alteration of mammalian target of rapamycin, mitogen-activated protein kinase, heart function markers (creatine kinase MB, lactate dehydrogenase, and aspartate amino transaminase), and heart histology of the diabetic control, which was ameliorated after treatment with Brazil nut and metformin, but their combined treatment was better than the single treatments.
Conclusion: This study shows that Brazil nut contains several bioactive compounds that support its biological properties as well as its candidature as a complementary therapy to metformin in mitigating cardiac complications arising from DM in rats.
期刊介绍：
Food & Nutrition Research is a peer-reviewed journal that presents the latest scientific research in various fields focusing on human nutrition. The journal publishes both quantitative and qualitative research papers.
Through an Open Access publishing model, Food & Nutrition Research opens an important forum for researchers from academic and private arenas to exchange the latest results from research on human nutrition in a broad sense, both original papers and reviews, including:
* Associations and effects of foods and nutrients on health
* Dietary patterns and health
* Molecular nutrition
* Health claims on foods
* Nutrition and cognitive functions
* Nutritional effects of food composition and processing
* Nutrition in developing countries
* Animal and in vitro models with clear relevance for human nutrition
* Nutrition and the Environment
* Food and Nutrition Education
* Nutrition and Economics
Research papers on food chemistry (focus on chemical composition and analysis of foods) are generally not considered eligible, unless the results have a clear impact on human nutrition.
The journal focuses on the different aspects of nutrition for people involved in nutrition research such as Dentists, Dieticians, Medical doctors, Nutritionists, Teachers, Journalists and Manufacturers in the food and pharmaceutical industries.
