Effect of water extract of bay laurel (Laurus nobilis L.) on non-alcoholic fatty liver disease (NAFLD).
Non-alcoholic fatty liver disease (NAFLD) involves lipid accumulation in liver without consumption of alcohol and affects many people worldwide. NAFLD is associated with metabolic syndrome disease such as obesity, insulin resistance, hyperlipidemia, and diabetes. However, there are no pharmacologic therapies for NAFLD. Recently, there are increasing reports that several natural plants can inhibit lipid accumulation in hepatocytes. Bay laurel (Laurus nobilis L.) leaves have been used in traditional medicine for rheumatism, stomach ache, emetic, skin rashes, and earaches. Our objective was to investigate the effect of bay laurel leaves water extract (BLW) on free fatty acid (FFA) treated hepatocyte and high fructose, high fat (HFHF) diet in a mouse model of NAFLD. In vitro, lipid accumulation increased only in the FFA treated group, while BLW reduced lipid accumulation to a level comparable to that only in the FFA treated group. Cellular antioxidants were increased in the BLW compared to the only FFA-treated group, but cellular MDA levels were decreased in the BLW compared to the only FFA treated group. Cellular lipid accumulation, inflammation, and apoptosis were reduced in the BLW compared to the only FFA treated group. In vivo, serum ALT, AST, and GGT levels in the BLW supplementation group were significantly decreased compared with the HFHF group. Hepatic TC, TG, and MDA levels were significantly decreased in the HFHF+100 and HFHF+200 groups compared to the HFHF group. The hepatic antioxidant activities in the BLW supplementation groups were significantly increased compared to the HFHF group. The expression of proteins related to hepatic inflammation and apoptosis was reduced in the BLW supplementation groups compared to the HFHF group. These results suggest that BLW could be potentially useful in the treatment of NAFLD due to its inhibitory effects on hepatic lipogenesis, hepatic inflammation, and hepatic apoptosis.
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.
