BACKGROUND Urinary tract infections (UTIs) are a very most common type of infection worldwide, and result in billions of dollars in medical care costs. Escherichia coli is the infective agent for 80-90% of all UTIs. Green tea, derived from leaves of the Camellia sinensis plant has been shown to have various potential health benefits (e.g., cardiovascular disease and cancer). The major beneficia...

Objective(s): Potentially preventable death from uncontrolled hemorrhage clearly indicates the importance of simple, fast and efficient ways to achieving hemostasis. The aim of this study was to develop a topical formulation of green tea extract for reducing bleeding that can be helpful in hemorrhage control.Materials and Methods: Hydroa...

Green tea (Camellia sinensis) contains several bioactive compounds which protect the cell and prevent tumour development. Phytochemicals in green tea extract (mostly flavonoids) scavenge free radicals, but also induce pro-oxidative reactions in the cell. In this study, we evaluated the potential cytotoxic and prooxidative effects of green tea extract and its two main flavonoid constituents epig...

BACKGROUND Compounds present in green tea have proved to inhibit the growth and activity of bacteria associated with infections. OBJECTIVES To assess the effects of green tea leaves extract in presence of propylene glycol on the aerobic mouth bacteria load. MATERIALS AND METHODS Saliva of 25 volunteer girl students aging 20-25 years were selected and evaluated by a mouthwash sample containi...

OBJECTIVE To determine the in vitro inhibitory activity of green tea extract on some clinically isolated cariogenic and periodontopathic bacteria. MATERIALS AND METHODS Twenty strains of each of Streptococcusmutans, Aggregatibacteractinomycetemcomitans, Porphyromonasgingivalis, and Prevotellaintermedia were isolated from carious teeth and periodontal pockets of patients with dental caries and...

Green tea catechin and green tea extract are now recognized as non-toxic cancer preventives for humans. We first review our brief historical development of green tea cancer prevention. Based on exciting evidence that green tea catechin, (-)-epigallocatechin gallate (EGCG) in drinking water inhibited lung metastasis of B16 melanoma cells, we and other researchers have studied the inhibitory mech...

OBJECTIVE Dental caries is a common infectious disease. Streptococcus mutans is the pre-valent decay microorganism. The anti Streptococcus mutans activity of non fermented and semi-fermented tea has been shown. The aim of this study was to determine the anti Streptococcus mutans activity of Iranian green and black tea (non fermented and fermented type). MATERIALS AND METHODS The study was exp...

Background: Physical exercise and herbal treatment with antioxidant property induce a favorable effect on glucose metabolism in diabetic patients. The aim of the present study was to investigate the effects of resistance training combined with green tea extract consumption on blood glucose and lipid profile in diabetic rats. Forty male Wistar diabetic rats aged 5 months and weights 290...

background and objective: although there are reports in the literature on the antimicrobial effects of green tea, the effect of black tea, the most common beverage in iran, on growth of bacteria, such as streptococcus pyogenes, has not been studied extensively. this study was undertaken to determine the inhibitory effect of black tea on the growth of streptococcus pyogenes in vitro and compare ...
