Activation of peroxisome proliferator-activated receptor (PPAR) serves as a key factor in the proliferation and invasion of breast cancer cells and is a potential therapeutic target for breast cancer. However, the mechanisms underlying this effect remain largely unknown. Heme oxygenase-1 (HO-1) is induced and overexpressed in various cancers and is associated with features of tumor aggressiveness. Recent studies have shown that HO-1 is a major downstream target of PPAR. In this study, we investigated the effects of induction of HO-1 by PPAR on TPAinduced MMP-9 expression and cell invasion using MCF-7 breast cancer cells. TPA treatment increased NF-B /AP-1 DNA binding as well as MMP-9 expression. These effects were significantly blocked by 15d-PGJ2, a natural PPAR ligand. 15d-PGJ2 induced HO-1 expression in a dose-dependent manner. Interestingly, HO-1 siRNA significantly attenuated the inhibition of TPA-induced MMP-9 protein expression and cell invasion by 15d-PGJ2. These results suggest that 15d-PGJ2 inhibits TPA-induced MMP- 9 expression and invasion of MCF-7 cells by means of a heme oxygenase-1-dependent mechanism. Therefore, PPAR/HO-1 signaling- pathway inhibition may be beneficial for prevention and treatment of breast cancer.

After analysis of Korean ancient novel CHUNHYANGIUN, it is revealed that 73 expressions are related to leisure. of these expressions, 41 expressions are related to religion and 24 expressions to mirth or pleasure in life. These two types of leisure comprise 89% of this novel. It means that Korean people in the past put stress on th pursuit of pleasure and religious life in the pross of laborious life. The novel has an attribute of leisure in its structure. Koreans in the past tried to be mirthful through leisure, but within the limits of regulations of their communities. In order to shed light on this spirit, we are supposed to make every effort to educate our ancestor's cultural life, especially leisure culture and resonable leisure behaviour.

The purpose of this study was to compare the obese and the normal weight girls in high school on the level of the recommended dietary allowances for the Koreans based on total energy intake, the ratio of 3nutrients intake, micro-nutrients intake, daily dietary intake and the ratio of 4nutrients intake by animality and vegetability. The results of this study are as follows:...............

Korean is exposed to a rapid growth in economy and considerable amount of time for leisure. There is no doubt that the leisure industry is playing a significant role in making our lives enjoyable and therefore leading a quality lift. In a range of research. it has been shown that the essence of leisure functions properly where the degree of leisure satisfaction is high. Thus, this study attempts to identify the cognition of leisure by undergraduate students in Kyongju University and to suggest alternative solutions for then. The research findings and their implications are summarized as follows. Firstly, a large percentage of the students take a serious view of work and leisure. Secondly, the satisfiers of own leisure activity are rather than dissatisfied students, because they regard their leisure activities as reasonableness and soundness. Lastly, students consider leisure as their mental state of comformt and pleasure. The results implies that systematic and in-depth education on the leisure and enrichment of leisure facilities are required in order to become higher students' satisfaction of own leisure activities.

Tourist have been, is now, and will be increasing all over the world. Therefore we need to tourist activities which are playing an most important role in modern society, in order to manage the activities reasonably. But the tourist behavior of Koreans visiting foreign countries is now in serous problems. The purpose of this study is to analyze this behavior by examining several news in the past 7 years. In result, it is revealed that bad behavior of Korean tourists in foreign countries includes excessive consumption, ignorance of public orders and other unhealthy activities. And short and long term steps are suggested here to eliminate such bad behavior. As for short term steps, we need to control tourist activities directly, to campaigndesirable tourism movement, and to provide information for tourists to choose reasonably. And as for long term and fundamental steps, we need to lead tourists to perform desirable tourist activities by teaching them the true meaning of tourism and the importance of community through lifetime education.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

The nitrite content, VBN(volatile basic nitrogen) and bacterial count in pork sausage stored at various temperatures were examined for the evaluation hygienic condition of meat products. 1.Nitrite content of pork sausage was decreased from 3.1ppm to 2.2ppm in 25 days at 7℃, from 3.1ppm to 0.8ppm in 5 days at 25℃, and from 3.1ppm to 0.4ppm in 5 days at 36℃, respectively. 2.Nitrite content of pork sausage in which potassium nitrite was added was, however, increased from 3.1ppm to the maximum amounts of 15.2ppm, 118.3ppm and 97.6ppm when kept for 35 days at 7℃, 30 clays at 25℃ and 26 days at 36℃, respectively. 3.Content of VNB of pork sausage with potassium nitrate was increased from 11mg% to 40mg% after the storage for both 35 days at 7℃, 5 days at 25℃ and 5 days at 36℃. The bacterial counts of the pork sausage of 7˚, 25˚ and 36℃ groups were increased from 103 to 104,109 anti 109, respectively.
