Background Excessive intake of fat, one of the causes of obesity, is associated with low-grade infammation in various susceptible organs and eventually causes tissue toxicity. This study examines the multifaceted suppressive efects of Korean red ginseng extract (KRG) on high-fat diet (HFD)-induced lipotoxicity and infammatory responses in the aorta, liver, and brain. Methods Male C57BL/6 mice were fed HFD with or without KRG for 12 weeks. The improvement efect in KRG on lipotoxicity and infammatory potential was determined in the blood and the aorta, liver, and brain tissues. Results KRG signifcantly inhibited 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity by >20% in vitro. KRG supplementation suppressed HFD-associated body weight gain, lipid profle changes, and excessive fat deposition in the liver and increased leptin, insulin, and ALT levels in the blood. Infammatory markers in the aorta, liver, and brain were also signifcantly reduced by KRG treatment. In microvascular endothelial cells, the 15% cyclic stretch-mediated upregulation of ICAM-1 and vascular cell adhesion protein-1 (VCAM-1) expression was signifcantly attenuated in the presence of KRG. Conclusion KRG supplementation attenuates HFD-mediated body weight gain, lipid profle changes, and multi-tissue infammatory responses.

Molphologic study of platelet have been done by many authors for the past years, they investigated that the heterogeneity of platelet size was shown even in normal person and various hematologic disorder. In the past the platelet size was not utilized in clinical medicine because of its technical difficulties of measuring. Recently, and automated blood cell counter, Coulter counter Model Splus Ⅱ®, was introduced and platelet size could be easily gained, which expressed by mean platelet volume(MPV). Therefore, this study was planned to evaluated the clinical significance of MPV in health person and various hematologic disease. The following results were obtained: 1. In healthy person, MPV was decreased along with increasing the platelet number. 2. In thrombocytopenic patients, MPV was decreased more than normal. 3. In various hematologic disease, MPV was decreased in acute leukemia, marrow failure and aplastic anemia, normal in iron deficiency. anemia, increased in reactive marrow, MPV was varied by platelet number in various hematologic disease. This disclosed that MPV was related with marrow function and production of megakaryocytes. From these results, MPV could be used as a valuable parameter in the evaluation of platelet together with measuring the platelet number. Particular relation-ship between MPV and various hematologic disease were not observed. We should be more study for MPV.

The flora and insect fauna of Mt. Waryong was surveyed. The flora was surveyed from 1998 to 2001 and insect fauna was done from spring to autumn of 2000. The vascular plants collected from this region are 815 taxa: 41 orders, 133 families, 476 genera, 702 species, 1 subspecies, 96 varieties, and 16 forma. In the area, Korean endemic plants were 18 taxa(2.2% among total 815 taxa); cultivated plants were 154 taxa (18.9% among total 815 taxa). Also the naturalized plants were 48 taxa(5.9% among total 815 taxa and 26.7% among the total naturalized plants in Korea): 19 families, 40 genera, and 8 species. The total insect specimens were classified into 6 orders, 53 families, and 239 species. In hemiptera, 11 families and 25 species were classified, and 8 families and 28 species were contained in homoptera. diptera held 6 families and 11 species, hymenoptera had 4 families and 9 species, and coleoptera had 4 families 35 species. And we could classified 20 families and 131 species in lepidoptera.

The purpose of this study was to test the effects of aerobic rhythmical exercise program on blood pressure, pulse and the life satisfaction of the elderly. This quai-experimental study was designed as a non-equivalent control group pretest-posttest study. The subjects were 36 subjects(experimental group: 19 subjects, control group: 17 subjects), aged between 65 and 73 years who have normal cognition, sensory function and cerebellum function. Aerobic rhythmical exercise program was developed on the basis of aerobic exercise, Korean tradititional dance and music by the author. The blood pressure, pulse rate and life satisfaction were measured prior to and following the experimental treatment. Data were analyzed with x^2-test, t-test, mean, standard deviation, percentage of change and ANCOVA test using SAS program. The results were as follows. 1. There was no significant difference of systolic blood pressure between experimental and control group following the aerobic rhythmical exercise program(F=1.39, P=0.247). 2. The diastolic blood pressure of the experimental group was significantly lower than that of control group following the aerobic rhythmical exercise program(F=2.96, p<0.1). 3. There was no significant difference of resting heart rate between experimental and control group following the aerobic rhythmical exercise program(F=0.07, P=0.793). 4. The life satisfaction of the experimental group was significantly higher than that of control group following the aerobic rhythmical exercise program(F=9.94, p<0.01). On the basis of the above findings, aerobic rhythmical exercise program is effective in reducing diastolic blood pressure and promoting life satisfaction of the elderly. Thus, this program can be recommended as an effective nursing intervention for the elderly.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with fiorisil, and finally analyzed simultaneously the organophosphorus pesticides using GC/NPD, Ultra-2 and Ultra-1 fused silica capillary columns were used to separate and identify the products. Recovery of most analytes from soybean sample, taken from pesticide residues well, was greater than(80%) for all except(6) analytes. This method can simultaneously determine multiple pesticides with a high degree of accuracy and precision.
1920년대 초 '開闢' 誌에 등장하는 주택개량론의 성격

This study investigates the discourses of "Housing Improvement" in 「KaeByeok」 from 1920, June to 1926, August. They are produced by "Culture Movement" advocates, whose main concern was in improvement of housing as a social residence from traditional to modern style, rather than spacial improvement of housing itself. So the discourses dealt with housing as a installation or a supplement for modernization of family life, and insisted on improving traditional housing to support modern life style. These situation are understood as unique character of housing improvement discourses of early 1920s as well as distinguished property from those produced by architects after mid 1920s.
