This study was performed to investigate the effects of green tea activities 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 activities were measured for experimental rats, and analyzed the activities 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.

The effects of water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats weighing 100±10 g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Control diet, animal, plant high fat diet and control and high fat diets with 2% water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups. The concentrations of serum triglyceride in rats fed the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower were lower than those in other groups. The concentrations of total cholesterol in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower group were lower than those in high fat diet groups. The concentrations of HDL-choleslerol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were tended to be lower than those of other groups. GPT and GOT activities were decreased in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups and than in the high fat group. LDH activity was lower in the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups than in the high fat group. These results suggest that water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

Biological phosphorus removal is characterized by complex interactions between different intracellular components of energy as PHA. Therefore, fundamental understanding of the behavior of the intracellular components and their influence on the removal of phosphorus is essential before control strategies to stabilize the proper process. The purpose of this study is to investigate relationship between release of phosphorus and synthesis of intracellular storage polymer. Mass of stored intracellular storage polymer was 21.2 ㎎ PHA/L, 28.8 ㎎ PHA / g MLSS. And phosphorus release/ intracellular storage polymer synthesis rate was 1.8545 ㎎ stored polymer/㎎ Phosphate. In the aerobic phase, mass of PAOs synthesis is 49.37 ㎎ PAOs/L. And PAOs fraction was 6.7-6.9%. Thus intracellular storage polymer synthesis by PAOs is calculated as 493㎎ PHA / g PAOs.

In this study, we isolated lactic acid bacteria from kimchi, which were identified as Pediococcus pentosaceus and Lactobacillus bevis by using API 50 CHL Kit, some morphological and physiological tests. The water extract of green tea(50, 100, 500, 1000ppm) inhibited the growth of Pediococcus pentosaceus and Lactobacillus brevis in broth system. Furthermore, their time were prolonged to about 4 hours at 500 to 1000ppm. The leakage amount of intracellular materials and Mg^(++) in tested bacteria cells increased with increasing concentration of green tea water extract.

The aim of this study was to investigate the behaviors of Self-Purchasing Snack(SPS) and the related factors. So, I've investigated and analyzed the general dietary habits and the eating behaviors related to SPS, the subjects of which were 300 high school students living in Iksan(150 boys, 150 girls). The result was as follows. Of going without meal per meal, breakfast 70%, lunch 35.7%, and dinner 50.7% turned out to do it more than three or four times a week and SPS rate of girls was higher than that of boys(P<0.05). I think busy daily schedule lead to irregular dietary habit by making breakfast skipped and this increases the frequency of having junk food and is linked to the cause of skipping lunch or dinner. Also being the loss of appetite, of the reasons for going without meals, took up the most rate and 21.0% of the girls turned to go without meals to help control their weight. For an unbalanced diet, there is no difference between boys and girls, 67.7% of whom turned to have an unbalanced diet more than three or four times and taste(53.2%), of the reason for it, took up the highest rate. For the pace of meal, 53.2% of boys and girls turned to eat quickly. I guess the short mealtime must be the practice because of early school attendance time and pressing lesson. For overeating or not, 24.0% of the subjects responded overeating and boys turned to overeat more than girls(p<0.05). For the frequency of eating between meals, 34.0% of the subjects responded that they did it once or twice a week. Because the increase of eating between meals raised concerns that it may be linked to irregular dietary habit, special education is required at school and at home. For the time of eating between meals, 67.7% of the subjects responded when wanting to eat and the response of girls were higher than that of boys(p<0.05). The place for eating between meals turned to be supermarket(55.6%), the store before the school(20.7%), the store of selling powdered food(16.0%). As preferred junk food, sweet stuff(34.3%) turned to be the most, ramyeon(27.7%), bread(22.3%), milk and dairy products(9.3%). Among boys ramyeon(22.3%) was the most and among girls sweet stuff(24.3%) the most. The rest turned to be similar by and large(p<0.05). When they select junk food, they considered taste(44.3%), mood at the time(23.7%), price(20.0%). For the reason for eating between meals, 53.3% of the subjects responded 'hunger'. I guess this is because of the result of the irregular dietary habit. Throughout the above result, we can see our youth's dietary habit and ways to select junk food be wrong. Therefore, I think policy consideration and nutritional education must be supported at a national level as well as at home to create their right dietary life environment or dietary habit, and to help select junk food properly.

Nanboroku is Japanese book of tea written by Mr. Nanbo-sokei who was the ablest pupil of Mr. Sennorikyu(1522~1591) and is said to be completed in 1593. In this study, Sennorikyu's opinion concerning meals served in the Japanese tea-ceremony was interpreted and the origin of the meals was clarified. The meal of the tea-ceremony is to be given not the extent of starvation, but in conformity with the manner of daily life in the Buddhism temple. It means not the plain foods, but it is to be served by understanding taste for the simple and quiet, that is Wabi and Sabi traditionally known in Japan. Also, the meals of forty-seven times served in the tea-ceremony given by Mr. Sennoriku in a certain year between 1582~1588, which are recorded in the volume No.2, and classified according to the kind and frequency of the menu and foods. Therefore the origin of the meals of tea-ceremony in the present age was clarified.

The effects of dried green tea leaf powders on serum lipid concentrations were evaluated in rats. Sixty male Sprague-Dawley rats weighing 100±10g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets: Normal fat diet and normal and high fat diets with 1% dried green tea leaf powders. Tissue weights of live, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by dried green tea leaf powders groups. The concentrations of serum triglyceride in rats fed the dried green tea leaf powers were lower than those in other groups. The concentrations of total cholesterol in green tea leaf powders the were lower powders green tea were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the dried green tea leaf powders groups were tended to be lower than those of other groups. GPT and GPT were decreased in dried green tea leaf powders groups and than in the high fat groups. LDHase was lower in the dried green tea leaf powders groups than in the high fat group. These results suggest that dried leaf powders green tea groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.
