Multidrug resistance and various adverse side effects have long been major problems in cancer chemotherapy. Recently, chemotherapy has gradually transitioned from mono-substance therapy to multidrug therapy. As a result, the drug cocktail strategy has gained more recognition and wider use. It is believed that properly-formulated drug combinations have greater therapeutic efficacy than single dr...

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 ...

We tested the hypothesis that green tea prevents diabetes-related tissue dysfunctions attributable to oxidation. Diabetic rats were treated daily with tap water, vitamins C and E, or fresh Japanese green tea extract. After 12 months, body weights were decreased, whereas glycated lysine in aorta, tendon, and plasma were increased by diabetes (P < 0.001) but unaffected by treatment. Erythrocyte g...

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...

green olive cultivars “manzanila” and “mission” were harvested at the mature green stage. they were either treated with 1-methylcyclopropane (1-mcp) at a concentration of 1.8 µl/l for 24 h at 20°c or kept untreated as a control. both treated and untreated fruits were then immersed in water containing cacl2 of 0 (control), 50 and 100 mm for 2 h under 1.2 bar pressure. fruits were then surface dr...

The present study was conducted to investigate whether green tea may improve weight maintenance by preventing or limiting weight regain after weight loss of 5 to 10 % in overweight and moderately obese subjects. The study had a randomised, parallel, placebo-controlled design. A total of 104 overweight and moderately obese male and female subjects (age 18-60 years; BMI 25-35 kg/m(2)) participate...

Oxidative stress is a main mediator in nitric oxide (NO) -induced neurotoxicity and has been implicated in the pathogenesis of many neurodegenerative disorders. Green tea polyphenols are usually expected as potent chemo-preventive agents due to their ability of scavenging free radicals and chelating metal ions. However, not all the actions of green tea polyphenols are necessarily beneficial. In...

BACKGROUND Current interest in the role of functional foods in weight control has focused on plant ingredients capable of interfering with the sympathoadrenal system. OBJECTIVE We investigated whether a green tea extract, by virtue of its high content of caffeine and catechin polyphenols, could increase 24-h energy expenditure (EE) and fat oxidation in humans. DESIGN Twenty-four-hour EE, th...

this experiment was carried out to study the effects of corn and green gram intercropping on yield and some quality characteristics of forage at agricultural research station of gorgan during summer 2006 & 2007. the experimental design was a randomized complete block design (rcbd) with twelve treatments and four replications. a local green gram and corn single cross 550 were the crops used in t...
