Biochemical and toxicological properties of catechin remain unclear, e.g.; how catechin affects female offspring from undernourished pregnant dams. Here, to elucidate effects of low prenatal protein on female offspring health status, changes of enzymes which modify epigenetic marks related with metabolism in kidneys from newborns were investigated after continuously administering catechin extra...

The effects of oral feeding of aqueous extract of green tea leaf on alkaline phosphatase (ALP), acid phosphatase (ACP), alanine transaminase (ALT), aspartate transaminase (AST), sugar and total proteins were studied in the liver of cadmium treated rats. In cadmium control group sugar and protein levels were decreased and ALP level was significantly (p<0.001) decreased, whereas ACP, ALT and AST ...

Green tea extract is known to contain compounds that are able to produce antioxidant effects in many types of living cells. Treatment of cultured human hepatoma (HepG2) cells with green tea extract resulted in dramatically increased expression of at least 15 genes that are present on a commercial human drug metabolism gene array. RT-PCR was used to confirm the microarray results, and analysis o...

OBJECTIVE Although it has been demonstrated that the antioxidant properties of tea catechins reduce atherosclerotic lesions in various animal models of hyperlipidemia, it is not yet clear whether these catechins prevent hyperlipidemia-independent arterial remodeling induced by balloon angioplasty. We evaluated the influence of the administration of the tea extract on vascular remodeling in a ra...

The present study was designed to investigate the effects of the extract of green tea and/or ginger on some hematological and immunobiochemical profiles in alloxan-induced diabetic rabbits. The results revealed that treatment of diabetic animals with extract of green tea and/or ginger elevated the decreased HDL-c and LDL-c but significantly decreased triglycerides, the elevated glucose and GOT ...

There is an interest in the development of an antioxidant packaging fully biodegradable to increase the shelf life of food products. An active film from cassava starch bio-based, incorporated with aqueous green tea extract and oil palm colorant was developed packaging. The effects of additives on the film properties were determined by measuring mechanical, barrier and thermal properties using a...

To evaluate the pharmacodynamic interaction of green tea extract with hydrochlorothiazide against isoproterenol induced myocardial infarction wistar albino rat of either sex were prophylactically treated with hydrochlorothiazide (10 mg/kg for 7 days), low and high dose of green tea extract (100 and 500 mg/kg for 3 weeks) and their combination by oral route. To induce the toxicity apart from nor...

In a previous study (Z Y. Wang et ci., Cancer Res., 52: !!62—1!70, !992),wefoundthatadministrationof a waterextractof greentealeaves as the sole source of drinking fluid inhibited ultraviolet B light (UVB) Induced carcinogenesis in SKH-! mice previously Initiated with 7,12dimethylbenz[alanthncene (DMBA). In the present study, we compared the effects of black tea, green tea, decaffeinated blac...
