Diabetes is one of the most common metabolic disorders and is interrelated to oxidative stress-induced diseases. According to the role of dietary antioxidants in control and prevention of diabetes, this study was aimed to evaluate the effect of green tea extract on serum glucose levels and serum and hepatic total antioxidant capacity (TAC) and lipid (MDA) in diabetic rats. Experimental diabetes...

The aim of this study was to investigate whether green tea extract has beneficial effect on gentamicin-induced acute renal failure. The investigation was conducted on thirty-two Wistar rats divided into four groups of 8 animals each. Control (C) group received normal saline. GT group received green tea extract orally, 300mg/kg. GM group received gentamicin intraperitoneally, 100mg/kg and GT+GM ...

Aim: The aim of this in vitro study is to evaluate the change in color and shear bond strength of enamel bleached with different concentrations of carbamide peroxide and green tea extract solution. Materials and Methods: The specimens are grouped as follows:Group –A: 16 % carbamide peroxide,Group –B: 16% carbamide peroxide & green tea extract, Group –C: 21% carbamide peroxide, Group -D: 21% car...

Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disorder in which the level of oxidative elements in blood rises. Green tea is a potent antioxidant since it contains catechins. In this study, the effect of hydro-alcoholic green tea extract on PCOS rats was examined. For PCOS induction, 96 mature Wistar rats were given estradiol valerate. After 60 days, the rats were divided int...

in this study, the effect of green tea extract was studied on quality of surimi produced from fish silver carp during refrigerated storage. surimi was prepared and immersed with various concentrations of tea extracts (0, 2 and 4%). samples were refrigerated for 15 days and were performed chemical tests include ph, total volatile bases nitrogen (tvb-n), thiobarbitoric acid (tba) test and total b...

The effect of green tea extracts on the sporulation of oocysts of 3 species of Eimeria was investigated. The unsporulated oocysts were exposed to 0%, 5% and 10% of green tea extracts (1 and 2% strengths, w/v). A new sporulation inhibition bioassay was designed to evaluate the anticocccidial activity of the tea extracts. The results showed for the first time that water-soluble extracts from gree...

OBJECTIVE To examine the effect of green tea extract on body weight, serum levels of glucose, and lipids in streptozotocin-induced diabetic rats. METHODS This experimental study was carried out in the Diabetes Research Center, Ahvaz University of Medical Sciences, Ahvaz, Iran from January 2011 to March 2011. Forty-eight male wistar rats (200-250 g) were divided randomly into 6 groups. Diabete...

background: atrazine (atz) is a common herbicide in agriculture for control of grass and broad-leaved weeds. it persists in the environment and causes reproductive problems in both human and animals. the present study was aimed at protective effect of green tea against atz toxicity in the reproductive system of male rats. methods: the present study was performed in veterinary school, shahid bah...

Free radical-induced oxidative damages of macromolecules and cell death are important factors in the pathogenesis of ischemia/reperfusion brain injury. In the present study, an investigation as to whether green tea extract reduces ischemia/reperfusion-induced brain injury in Mongolian gerbils was conducted. The effect of green tea on the ischemia/reperfusion-induced production of hydrogen perox...

Background and Objective: Diabetes causes fertility disorders by interfering with the endocrine gland function. There are reports that, green tea and catechins could have anti-oxidant and hypoglycemic properties. Therefore, in the present study, we evaluated the effects of green tea aqueous extract and catechin influence on pituitary-gonadal axis in rat models of type 1 diabetes. Materials & M...
