This study was performed to investigate the effects of green tea activites in rats with administration of aluminum in drinking green tea. Male Sprague-Daweley rats were divided into five groups consisting of the control, aqueous green tea at the level of 1.5%, a aquous green tea(1.5%) and aluminum sulfate solution 500ppm, before the 2 weeks administration by aquous green tea(1.5%) and after the 2 weeks aluminum sulfate solution 500ppm, aluminum sulfate solution 500ppm. After 4weeks of feeding, serum enzymes activites were measured for experimental rats, and analyzed the activites of alanine amino trans aminase(ALT), asparate amino transminase(AST) , lactate dehydrogenase(LDH), cholinesterase(ChE). Comparing to control group, Alanine amino trans aminase (ALT) was decreased in aqueous green tea administrated group and increased significantly administration by aluminum sulfate solution 500ppm group. Alanine amino trans aminase(ALT) was decreased administration by aqueous green tea group and Increased addition to aluminum sulfate solution 500ppm group as compared to control group. Lactate dehydrogenase(LDH) was increased compared to control group by experimental group and increased significantly administration by aluminum sulfate solution 500ppm. Cholinesterase (ChE) activity was decreased compared to control group by experimental group.
