This study was performed to investigate the effect of serum enzyme activities in rats after administration of aluminum compound. Seventy five male Sprague-Dawley rats were divided into five groups consisting of control, $250\;ppm\;AlCl_3,\;500\;ppm\;AlCl_3,\;250\;ppm\;Al_2(SO_4)_3$ and $500ppm Al_2(SO_4)_3$ groups and kept on the diet for 2 weeks. The weight gain increased from 0.53 to 3.35% in $AlCl_3$ adiministration groups but decreased from 2.82 to 6.16% in $Al_2(SO_4)_3$, administration groups as compared to control group. As compared to control group, activities of lactate dehydrogenase (LDH) and aspartate amino transaminase (AST) in serum increased 29.43 to 57.68% and 0.68 to 9.97% in $AlCl_3$ adiministration groups, and 74.60 to 29.33% and 21.04 to 24.79% in $Al_2(SO_4)_3$ adiministration groups, respectively. However, alanine amino transminase (ALT) decreased from 12.69 to 25.42% in $AlCl_3$ adiministration groups and from 24.32 to 39.62% in $Al_2(SO_4)_3$ administration groups. Cholinesterase activity increased from 28.98 to 12.73% as compared to control group by administration of $AlCl_3$ and decreased from 3.93 to 14.48% by administration of $Al_2(SO_4)_3$.

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.
