background: type 2 diabetes is a global health problem and a major cause of illness. exercise, diet and medication are the three pillars in the treatment of type 2 diabetes. objective: the aim of the present study was to investigate the effect of aerobic training combined with green tea hydroalcoholic extract consumption on blood glucose and lipid profile on diabetic rats. methods: diabetes was...

We manufactured a new fermented tea by tea-rolling processing of third-crop green tea (Camellia sinensis) leaves and loquat (Eriobotrya japonica) leaves. The mixed fermented tea extract inhibited pancreatic lipase activity in vitro, and effectively suppressed postprandial hypertriacylglycerolemia in rats. Rats fed a diet containing 1% freeze-dried fermented tea extract for 4 weeks had a signifi...

introduction: the aim of this study was to compare the antibacterial effect of persian green tea extract (gte) and 2.5% sodium hypochlorite (naocl) against enterococcus faecalis ( e. faecalis ) as an intracanal irrigant. methods and materials: thirty freshly extracted teeth were instrumented and sectioned into mesial and distal segments. the specimens were put into wells containing 2 ml of e. f...

background: green tea is one of the most popular beverages in the world. it is believed to have beneficial effects in the prevention and treatment of many diseases, one of which is nonalcoholic fatty liver disease (nafld). the present study investigated the effects of consumption of green tea in nafld patients. methods: this study was a double‑blind, placebo‑controlled, randomized clinical tria...

oxidative and microbiological degradations are the main factors that determine the quality of food and the shelf life. color and moisture stability are important quality attributes that contribute to meat shelf life, salability and consumer acceptability. there is currently considerable interest in edible films coatings and natural antioxidants because of their potential to improve the quality ...

Dietary supplementation with powder of a green tea extract suppressed the enhancement of plasma alanine aminotransferase and aspartate aminotransferase activities induced by D-galactosamine, but not by carbon tetrachloride, in a dose-dependent manner in rats. The minimum dose to cause a significant effect was 1 to 2%. Drinking green tea also suppressed plasma enzyme activities. These results in...

The effect of p.o. administration of tea on nitrosamine-induced carcinogenesis was investigated. Female A/J mice were given /V-nitrosodioth) lamine (NDEA) (10 mg/kg) p.o. once a week for 8 weeks and were killed 16 weeks after the last dose. More than 90% of the mice had forestomach and lung tumors. The animals had an average of 8.3 forestomach and 2.5 lung tumors/mouse. With 0.63 or 1.25% green...

Article history: Received on: 12/05/2013 Revised on: 19/10/2013 Accepted on: 07/12/2013 Available online: 31/12/2013 Food derived antioxidants have a strong potential for long term use as chemo-preventive agents in disease states involving oxidative stress such as tea. This study was done to clarify the potential effect of green tea extract in protecting the liver from lipopolysaccharide (LPS)-...

This study investigated the antioxidative activity of green tea extract, and a green tea tannin mixture and its components, under conditions of radical generation using the hydrophilic azo compound, 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) to generate peroxyl radicals at a constant and measurable rate in the cultured renal epithelial cell line, LLC-PK(1), which is susceptible to oxi...
