Black ginseng was made by steaming raw white ginseng nine times at $100^{\circ}C$ for 2 h and drying. We then performed pilot experiments using the nine black ginseng extracts for different steaming and drying times to determine their anti-obesity effects. Two ginseng extracts, steaming and drying five times (FSFD) and steaming and drying nine times (NSND), prepared in water or ethanol solution decreased lipid accumulation of 3T3-L1 cells. FSFD in water and ethanol extracts showed higher levels of ginsenosides, in particular, Rh1, Rg2, and Rb1 than NSND, and levels of the three ginsenosides were higher in ethanol extracts than in water extracts. Treatment with FSFD and/or NSND in ethanol extracts significantly regulated $PPAR{\gamma}$, C/$EBP{\alpha}$ and AMPK phosphorylation in 3T3-L1 cells. We verified doubling time of stem cells from both abdominal fat and subcutaneous fat after FSFD and NSND in ethanol and water extracts were added. Although addition of FSFD and NSFD in water extracts had no effects on proliferation, ethanol extracts with FSFD and NSND increased doubling time of stem cells in subcutaneous fat. FSFD and NSND in ethanol extracts more effectively reduced adipogenesis compared to those in water extracts. FSFD in ethanol extracts promoted secretion of anti-inflammatory cytokine such as IL-10 and depressed MCP-1 infiltration in 3T3-L1 preadipocytes co-cultured with RAW264.7 cells. We concluded that FSFD and NSND ethanol extracts may be developed as a functional food for its anti-obesity effect, but anti-inflammatory effect was shown in ethanol extracted FSFD rather than in NSND.

The purpose of this study was to verify the effects of a conflict resolution program on conflict resolution strategies and friendship quality of children. The subjects of this study were higher-grader students of elementary school. Out of the students, 18 were into the experimental group, while the rest were into the control-group. The experimental design was the pretest-posttest control group design, and the 50-minutes conflict resolution program was treated for the experimental group twice per week (a total of 11 sessions). The scale of conflict resolution strategies presented by Ha Ji Wean (2005) and the scale of friendship quality of children presented by Rhee Un Hai and Koh Yun Joo (1999) were used as the measurement tools in this study. In order to supply the limitations of quantitative data, the journals of group participation of each session and the participation reports after the completion of the program were qualitatively analyzed. The results of hypotheses verification were as follows; First, conflict resolution strategies conflict was significant difference in enhancement of the compromising-integrating strategy and the obliging strategy, and reduction of the dominating strategy. Second, friendship quality was significant difference in enhancement of the friendship positive function, and friendship satisfaction, and in reduction of the friendship negative aspect, The results of the study confirmed that the conflict resolution program affected both conflict resolution strategies and the friendship quality of children.

In this study, an educational program was developed. The program can perform the claim for examination of medical expense, which is one of NCS Competence Unit Elements for hospital administration. Considering various coding to complex compute and process, VB.Net was employed for this development. For database, ACCESS Database was used because it is easy to learn and use. The learning effects by the developed program are expected to be as follows. First, the composition of medical expense can be understood by analyzing Medical history and then selecting insurance code according to the Standard of Medical Care Code. Second, unit cost per score can be learned according to hospital class. Third, selection of Column (medical materials) and Column II(medical practice) can classify items of additional ratio. Fourth, because patient's payment rate on hospitalization and meal expense and use of special equipment are differently applied, user can know patient's payment rate by type and can calculate it. Fifth, additional amount is the amount calculated by additional ratio of Column II(medical practice), and user can learn additional ratio according by insurance type and hospital class. Sixth, user can learn self-pay rate by hospital class and understand the process that self-pay amount and claim amount are calculated according by self-pay rate.

The purposes of this study were to find out the effectiveness of instructional program developed utilizing various strategies to foster the students creativity in science and to analyze the recognition of the students as well as the science teachers on this program for the improvement of the program. Instructional program was consisted of student's worksheet and teacher guidebook. This program was applied to 93 7th grade students for three months. Result of this study showed that the students in experimental group got higher scores than those in the control group, which implied that creativity of the students could be promoted through specially designed program. Analysis of the change of creativity of the students by science achievement showed that the degree of promotion of creativity was higher as the achievement of the students becomes higher. Recognition on this program of the students and teachers who participated in this project revealed positive in that this program was different from the instructional program they have used and that this program would make the students eager to learn and explore the phenomena they faced. Students and teachers also indicated that shortage of instructional time, too many students in class, passive attitude of the students in class discussion, and so on as the problem they have to solve in running the program.

Glial cells such as astrocytes and microglial cells are the main source of proinflammatory cytokines and nitric oxide(NO) in the central nervous system, which exert neuroimmune and inflammatory functions and other various neurobiologic effects. Though Panax ginseng C.A. Meyer has been known to strengthen the body's defence mechanisms and also to maintain the homeostasis in the central nervous system, the effects of Panax ginseng on the production of immune and inflammatory mediators have not been studied well in the brain. Therefore, this study was designed to study the effects of ginseng saponins on the production of proinflammatory cytokines and NO in the primary cultures of mixed glial cells. White ginseng saponin, 200-500 $\mu$g/ml, showed significant cytotoxicity after 72 hrs and increased TNF-$\alpha$, IL-$\beta$, and NO production. Lower doses of 50-100 $\mu\textrm{g}$/ml showed little cytotoxicity until 72 hrs and also increased the production of TNF-$\alpha$, IL-1$\beta$, and NO. Triple immune staining showed that white ginseng saponin, 200$\mu\textrm{g}$/ml for 72 ks, induced stellation of astrocytes and iNOS expression exclusively in microglial cells. Taken together, the white ginseng saponin increased the production of proinflammatory cytokines such as TNF-$\alpha$ and IL-1$\beta$, and induced iNOS expression and NO production in mixed glial cell cultures, which may be ascribed to the enhancement of central immune responses and the regulation of inflammatory reactions by Panax ginseng.

This study was intended to identify the effectiveness of Lithospermum erythrorhizon in the UVB-irradiated mouse skin. The C57BL mice were divided into three groups; the control group, the UVB irradiated group(UVB group), and the group treated with Lithospermum erythrorhizon extracts after UVB irradiation(UVB+Le group). 10 mouses were collected and sacrificed at 24 hrs, 48 hrs, 72 hrs, 120 hrs, and 168 hrs, respectively. In the result, the transepidermal water loss (TEWL) was decreased the UVB+Le group than UVB groups by time. At the 168 hrs group was significantly lower(p<0.05). In the result, the melanin value was decreased in the UVB+Le group than UVB group, but meaningless(p>0.05). In the result of erythema index, the UVB+Le group was meaningfully lower at 24 hrs, 48 hrs, and 72 hrs group than UVB group(p<0.05). In the result of scanning electron micrograph observation, the UVB+Le group was allevited swelling than UVB group at the 24 hrs, formation of the scab at the 48 hrs, regular plate shap at the 72 hrs, new keratin observated at the 120 hrs partially, and fine fiber covered epidermis surface at the 168 hrs. In the result of transmission electron micrograph observation, the UVB+Le group was facilitation of increased lamellar bodies and reformation lamellar bodies than UVB group at the all groups. Almost all the structures were recovered at the 160 hrs group. In conclusion, Lithospermum erythrorhizon extracts may recovery on the UVB-irradiated mouse skin.

This case report is a treatment of patient with hemophilia A and autism. The patient's chief complaint was treatment of dental caries on entire dentition and he has an impacted mesiodens located on the apex of the upper right primary central incisor. The patient was consulted with pediatrician and anesthetist about the detailed discussion of the complexities of hemorrhagic disorder. Because he had some problems of behavior management and bleeding, the treatment was done under the gerneral anesthesia. The following results were obtained. 1. Consult with the patient's physician and hematologist about the replacement therapy and bleeding tendency. 2. For the severe hemophiliac child who requires extensive or surgical treatment, general anesthesia may be indicated for the comprehensive care. 3. For the hemophiliac child who has a behavior management problem due to autism and other defects, general anesthesia may be considerable. 4. Care must be taken during dental procedures not to causing a bleeding. 5. Local hemostatic methods must be acquired for the emergency state. 6. Neve prescribe aspirin or non-steroidal anti-inflammatory drugs such as ibuprofen, indomethacin, and phenylbutazone. These drugs affect platelet aggregation and exaggerate the bleeding defect. 7. Do not be afraid of hemophiliac patient, and never compromise quality of dental care.

The goal of this paper is to propose a new way to register CDA documents in CDR (Clinical Document Repository) that is proposed by the author earlier. One of the methods is to use a manifest archiving for seamless references and visualization of CDA related files. Another method is to enhance the CDA security level for supporting pseudonymization of CDA. The former is a useful method to support the bundled registration of CDA related files as a set. And it also can provide a seamless presentation view to end-users, once downloaded, without each HTTP connection. The latter is a new method of CDA registration which can supports a do-identification of a patient. Usually, CDA header can be used for containing patient identification information, and CDA body can be used for diagnosis or treatment data. So, if we detach each other, we can get good advantages for privacy protection. Because even if someone succeeded to get separated CDA body, he/she never knows whose clinical data that is. The other way, even if someone succeeded to get separated CDA header; he/she doesn't know what kind of treatment has been done. This is the way to achieve protecting privacy by disconnecting association of relative information and reducing possibility of leaking private information. In order to achieve this goal, the method we propose is to separate CDA into two parts and to store them in different repositories.

A 7-year-old, 3.16 kg intact male Yorkshire terrier had the history of abdominal distension, diarrhea, and weight loss. On the basis of history takings, physical examination, laboratory tests, radiography, ultrasonography, exploratory laparotomy, and histopathological examination, the dog was diagnosed definitely as intestinal lymphangiectasia. In this case, signs and results are consistent with those of other reports, but some clinicopathological findings such as hypocalcemia and hypocholesterolemia are not. This means that the findings were not completely in accord with the typical ones of intestinal lymphangiectasia in this dog. Prednisolone was prescribed to treat. However, it was not effective sufficiently. Thus, azathioprine was added to the regimen used in the first trial, and it was quite efficient in inducing remission in intestinal lymphangiectasia. The clinical signs were improved to the combined therapy. This case report demonstrates that the combined therapy for intestinal lymphangiectasia can be used as an alternative to only glucocorticoid therapy.

The mechanisms responsible for ischemia/reperfusion (I/R) injury have direct or indirect relevance to clinical lung injury after severe shock, cardiopulmonary bypass, and transplantation. This study investigated the effects of aspirin on intestinal I/R-induced acute lung injury (ALI) in rats. Lipopolysaccharide (LPS) induced cyclooxygenase-2 (COX-2) expression in A549 and RAW264.7 cells. RAW264.7 macrophages had shown greater expression of COX-2 than A549 cells. In addition, the NADPH oxidase inhibitor apocynin and p38 MAPK inhibitor SB203580 attenuated LPS-stimulated COX-2 expression. To induce ALI, intestinal ischemia was performed for 60 min prior to the 4 hr reperfusion by clamping the superior mesenteric artery in Sprague-Dawley rats. In order to test and compare the effect of non-specific COX inhibitor aspirin with the effect of mepacrine, a well known phospholipase$A_{2}$ inhibitor, rats were divided into 4 groups: Sham, I/R, Mepa+I/R (mepacrine, 60 mg/kg, i.p.), ASA+I/R (aspirin, 10 mg/kg, i.p.). In the present investigation, myeloperoxidase activities in the lung and intestinal tissues were increased by I/R. These changes were reduced by single pretreatment of mepacrine (60 mg/kg, i.p.) or aspirin (10 mg/kg, i.p.) 30 min before I/R. Structural studies demonstrated that the tissue injuries in the lung and intestine after I/R were also attenuated by the pretreatment of mepacrine or aspirin. These results suggest that I/R-induced ALI is mediated, in part, by the activation of COX. In addition, pretreatment of aspirin might be helpful for the prevention of ALI in ARDS-prone patients. In addition, the p38 MAPK inhibitor and apocynin also might be helpful to ALI through the inhibition of COX-2 expression.
