There are detailed descriptions of the clinical experiences and prescriptions of asthma in traditional Korean medicine. Zedoariae rhizoma is one of the Korean herbal medicines used to treat bronchial asthma and allergic rhinitis for centuries. However, the therapeutic mechanisms of this medication are still far from clear, In this study, a house-dust-mite (Dermatophagoides pteronyssinus [Der p])-sensitized murine model of asthma was used to evaluate the immunomodulatory effect of Zedoariae rhizoma on the allergen-induced airway inflammation in asthma. Three different protocols were designed to evaluate the treatment and/or long-term prophylacitic effect of Zedoariae rhizoma in Der p-sensitized mice. Cellular infiltration and T-cell subsets in the bronchoalveolar lavage fluid (BALF)of allergen-challenged mice were analyzed. Intrapulmonary lymphocytes were also isolated to evaluate their response to allergen stimulation. When Zedoariae rhizoma was administered to the sensitized mice before AC (groups A and C), it suppressed airway inflammation by decreasing the number of total cells and eosinophil infiltration in the BALF, and downregulated the allergen- or mitogen-induced intrapulmonary lymphocyte response of sensitized mice as compared to those of controls. This immunomodulatory effect of Zedoariae rhizoma may be exerted through the regulation of T-cell subsets by elevation or activation of the CD8+ and double-negative T-cell population in the lung. However, the administration of Zedoariae rhizoma to sensitized mice 24 h after AC (group B) did not have the same inhibitory effect on the airway inflammation as Zedoariae rhizoma given before AC. Thus, the administration of Zedoariae rhizoma before AC has the immunomodulatory effect of reducing bronchial inflammation in the allergen-sensitized mice. On the other hand, to determine the potentiality of prophylactic and/or therapeutic approaches using a traditional herbal medicine, Zedoariae rhizoma, for the control of allergic disease, we examined the effects of oral administration of Zedoariae rhizoma on a murine model of asthma allergic responses. When oral administration of Zedoariae rhizoma was begun at the induction phase immediately after OVA sensitization, eosinophilia and Th2-type cytokine production in the airway were reduced in OVA-sensitized mice following OVA inhalation. These results suggest that the oral administration of Zedoariae rhizoma dichotomously modulates allergic inflammation in murine model for asthma, thus offering a different approach for the treatment of allergic disorders.

The ratio of the elderly population is rapidly growing due to socio-economic development and better medical services. As the average life-span of the Korean elderly becomes longer, the proportion of the elderly is increasing. Therefore, the elderly need to sustain a high quality of life. However, all these factors, such as sensory loss, decreased endurance, mobility limitation, and a loss of independence, act to diminish the quality of life among the elderly. It is necessary for elders to adapt themselves to aging, to maintain their physical functions and especially, it is important to keep their independence in activity of daily living and self care. Therefore, this study was designed to identify the degree of activity in daily living and exercise of a self-care agency and to investigate the relationship between activity of daily living and self-care agency. Also, this research aimed to contribute to nursing interventions that maintain and promote quality of life of the elderly and to enable themselves to live independently. The subject of this study were 160 elders, over age 65, who were sampled in C city. Data were collected by observation and questionnaires from May,1999 to December, 1999. The measurement tools were Barthel Index(1979), Lawton & Brody(1969) for activity of daily living and Kearney & Fleischer(1979) for self-care agency. Data were analyzed by SAS PC+ package and included descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and Cronbach's alpha. The conclusions of this study are summarized as follows; 1. The mean of ADL and IADL was 96.09 and 16.38, respectively. The score described activity of daily living among the elders in C province as moderate. Particularly, in the items of IADL, the item of medication was the highest score. 2. The mean for exercise of self-care agency was 76.48, a moderate degree. 3. The degree of ADL and IADL according to demographic characteristics was significantly different statistically in pocket money, the presence of disease, perceived health status and in occupation, pocket money, family type, the presence of disease, and perceived health status, respectively. 4. The dagree of selt-care agency according to demographic characteristics was significantly different statistically in gender, education level, economic status, and pocket money. 5. There was a significant positive correlation between activity in daily living and self-care agency. Based on these results, further research is suggested to discover the variables influencing the activity of daily living and self-care agency to develop nursing strategies for improving self-care and activity of daily living among the elderly.

Extracellular matrix(ECM) is known to function as a reservoir of endogenous growth factors, can be an effective delivery system of growth factor that easily lost bioactivity in solution. Fibrillar collagens like type I collagen, are the major constituent of the ECM and structural protein of bone. Also, it can be a scaffold for osteoblast migration. The purpose of this study was to compare the effects of absorbable Atelo-collagen Sponge($Teruplug^{(R)}$) insertion in tooth extraction sites on periodontal healing of the mandibular second molar after the extraction of the impacted third molar. The study population comprised 31 cases who had been scheduled for surgical removal of impacted mandibular third molars. All patients were in good general health and were not using any medication that would influence wound healing after surgery. In 15 cases control group, none was inserted into the tooth extraction site. In 16 cases experimental groups, $Teruplug^{(R)}$ was inserted into the tooth extraction site. We evaluated tooth mobility, pocket depth, gingival margin level preoperatively and 1 week, 2 weeks, 4 weeks, and 3 months postoperatively. The change was compared with two groups using Mann-Whitney test. The results were as follows. 1. There was no significant change of tooth mobility on both groups. 2. There was tendency of decreasing of previous pocket depth causing tooth extraction on both groups. 3. On gingival margin level, there was various change according to initial swelling and loss of attachment on both groups. 4. There was tendency of decreasing of gingival margin level on both groups because of removal of inflammation and decreasing of previous pocket depth. 5. There was large change of pocket depth on buccal middle, distal, lingual distal area because of tooth extraction and bone reduction. Compared with the control group and experimental group, we observed significant difference during some periods. The results of this study suggest that absorbable atelo-collagen sponge($Teruplug^{(R)}$) is relatively favorable bone void filler with prevention of tissue collapse, food packing and enhance periodontal healing.

1. Objective The object of this study was to understand the clinical characteristics of the Taeeumin Symptomatic Pattem. 2. Methods The patients visiting the department of Sasang Constitution of Traditional Korean Medicine clinic from June to November of 2008 were used in this study. Those who showed a favorable turn after over ten days of medication and who showed up for at least two follow-up sessions were chosen among first-time visitors. Of these, 75 patients identified and verified to be of the TE type were chosen for the study sample. The Taeeumin were verified into two groups according to clinical symptoms into Exterior Cold Disease and Interior Heat Disease groups, of which the Interior Heat Disease group was further subdivided into the Galgeun-medicament group and the Cheongshimyeonja-tang group, based on questionnaire results. The Exterior Cold Disease group was set as the control group in order to contrast and compare it with the study group, the Interior Heat Disease group. 3. Results and Conclusions The questionnaire items shown to differentiate the Exterior Cold Symptomatic Patterm and the Interior Heat Symptomaic Pattern (indicating Heat-affceted Liver Symptomatic Pattern) were related to "dryness of stool," "dark urine colorm," "dryness of nose," and "dryness of lips." The items shown to differentiate the Galgeun-medicament group and the Cheongshimyeonja-tang group (of the Dry - Heat Symptomatic Pattern) were related to "nausea," "stifling sensations and palptation," "disturbed sleep," and "dizziness." Therefore, the sleep pattern, palpitation, dizziness, and nausea can be said to be indicators of the Interior Heat Symptomatic Pattern, and Dry-Heat symptoms are better distinctions between the Chongshimyeonja-tang group and the Galgeun-medicament group than Heat-affected Liver symptoms.

Purpose: Obese proportion is increasing universally, estimating more than a billion. So reducing the weight became one of the topic in medical market. Not only diet, exercise, medication, but also many surgical procedures are being developed, such as sleeve gastrectomy, gastric bypass surgery. After massive weight loss, skin excess and laxity occurs, leading to unsatisfying body contour. Body contouring surgery including abdominoplasty, breast reduction is performed when skin excess is present in abdomen and breast. When skin excess is present circumferentially, belt dermolipectomy is the treatment of choice. Methods: A 23-year-old man had weight gain since he was 12 of age. A year before visiting to our department, his height was 168 cm, weight was 150 kg and body mass index (BMI) was 53.15 kg/$m^2$. The patient lost 55 kg of his weight through exercise and diet control. When he visited again, his weight was 95 kg and BMI was 33.66 kg/$m^2$. In physical examination, skin excess and laxity was seen in both breast and abdomen circumferentially and lateral folds were seen in the back. Abdominal contour deformity (Pitman classification type 6) and pseudogynecomastia (grade 3) were present in both breast. Belt dermolipectomy of abdomen, both breast and lateral folds was performed, resecting 6,400 g of tissue and additive 1,200 g through revisional operation. Results: The patient lost 6,500g of his weight and BMI reduced by 2.3 kg/$m^2$. The patient's hospital course was uneventful during 5 weeks of hospitalization and he was satisfied with his final body contour. Conclusion: Body contouring with belt dermolipectomy in patient who has circumferential skin excess and laxity after massive weight loss can be a treatment of choice.

The study was aimed at developing an independent hospice center model that would be best suited for Korea based on a literature review and the current status of local and international hospices. For the study, five local and six international hospice organizations were surveyed. Components of the hospice center model include philosophy, purpose, resources (workers, facilities, and equipment), allocation of resources, management, financial support and hospice team service. The following is a summary of the developed model: Philosophies for the hospice center were set as follows: based on the dignity of human life and humanism, help patients spend the rest of their days in a meaningful way and accept life positively. On the staff side, to pursue a team-oriented holistic approach to improve comfort and quality of life for terminally ill persons and their families. The hospice center should have 20 beds with single, two, and four bed rooms. The center should employ, either on a part-time or full-time basis, a center director, nurses, doctors, chaplains, social workers, pharmacists, dieticians, therapists, and volunteers. In addition, it will need an administrative staff, facility managers and nurses aides. The hospice should also be equipped with facilities for patients, their families, and team members, furnished with equipment and goods at the same level of a hospital. represented by a center director who reports to a board and an advisory committee. Also, the center director administers a steering committee and five departments, namely, Administration, Nursing Service, Social Welfare, Religious Services, and Medical Service. Furthermore, the center should be able to utilize a direct and support delivery systems. The direct delivery system allows the hospice center to receive requests from, or transfer patients to, hospitals, clinics, other hospice organizations (by type), public health centers, religious organizations, social welfare organizations, patients, and their guardians. On the other hand, the support delivery system provides a link to outside facilities of various medical suppliers. In terms of management, details were made with regards to personnel management, records, infection control, safety, supplies and quality management. For financial support, some form of medical insurance coverage for hospice services, ways to promote a donation system and fund raising were examined. Hospice team service to be provided by the hospice center was categorized into assessment, physical care, emotional care, spiritual care, bereavement service, medication, education and demonstrations, medical supplies rental, request service, volunteer service, and respite service. Based on the results, the study has drawn up the following suggestions: 1. The proposed model for a hospice center as presented in the study needs to be tested with a pilot project. 2. Studies on criteria for legal approval and license for a hospice center need to be conducted to develop policies. 3. Studies on developing a hospice charge system and hospice standards that meet local conditions in Korea need to be conducted.

After the introduction of National Medical Insurance in 1989, the medical demand has rapidly increased. The impact of increased medical demand was followed by an increase in the number of claims in need of review. We studied a new, fair method for reducing the number of claims reviewed. We analysed 90,583 outpatient claims submitted between September and October; claims were made for services given August of 1994. We finally suggested a screening system for claims review using a statistical method of discriminant analysis of the medical costs. The results were as follows. 1. In the cut-off group, age, days of medication, number of hospital or clinic visits, and total charge were significantly high. The cut-off rates according to the hospital-type and existence of accompanied disease were significantly different 2. According to ICD, the cut-off rate was highest in peripheral enthesopathies and allied syndromes(20.76%), lowest in acute sinusitis(0.93%). The mean charges were significantly different according to ICD and existence of cut-off. 3. We build discriminant functions by ICD with such discriminant variables as patient age, sex, existence of accompanied disease, number of hospital or clinic visits, and 9 detailed hospital or clinic charges included in claim. 4. We applied the discriminant function for screening those claims that were expected to be cut-off. The sensitivities comprised from 40% to 70%, and specificities from 70% to 95% by ICD. Acute rhinitis had highest sensitivity(100.00%) and other local infections of skin and subcutaneous tissue had highest specificity(98.45%). The expected number of cut-off was 17,762(19.61%). The total sensitivity was 49.62%, the total specificity was 82.57% and the error rate was 19.66%. We lacked economic analysis such as cost-benefit analysis. But, if the new method of screening claims using discriminant analysis were applied, the number of claims in need of review will reduce considerably.

The appropriate care to the dental emergency patients is much important in the aspect of community dental service. To attain such a purpose, the sacred duty of the training of oral and maxillofacial surgeons is required. So, a retrospective study on the characteristics of dental injuries and diseases in emergency care unit will be very meaningful. This study was carried by reviewing the charts and radiographic films of 3,394 patients, treated for dental emergency at Wonju Christian Hospital, Republic of Korea, from January 1, 1993 to December 31, 2002. All patients were classified to 6 groups including trauma, toothache, infection, hemorrhage, TMJ disorder and the others. The clinical characteristics of diseases and treatment modalities according to each group were analyzed. The trauma (73.9%) was the most frequent cause in dental emergency patients, and acute toothache, odontogenic infection, oral hemorrhage, and TMJ disorder were next in order. Gender prediction was male (68%), there were many patients on May and December in the monthly frequency, and the most frequent age group was from 0 to 9 years. In the trauma group, male (68.6%) was predominant, and soft tissue injuries and primary closures were the most frequent type of injury and treatment. In jaw fractures, traffic accidents were the most cause and the weakest site was mandibular symphysis area, and mandibular angle, condyle, and body area were next in order. In the acute toothache group, the cause was dental pulpitis mostly and treatment for that was drug administration mainly. Buccal space abscess in infection group had the largest incidence (24.5%), and common treatments were incision and drainage and medications. In the hemorrhage group, a major cause was postoperative bleeding (60.3%) and hemostasis was obtained by pressure dressing, curettage and suture. For the TMJ disorder group, the peak incidence (63.8%) was shown in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medication such as analgesics and sedatives. In the other group, the various specific symptoms were complained due to acute sialadenitis, trigeminal neuralgia, acute stomatitis, chemical burn, terminal stage neuritis of head and neck cancer, and foreign body aspiration. In conclusion, for the rapid and proper care of the emergency dental diseases, well-trained education should be presented to the intern and resident course of oral and maxillofacial surgery. And it is demanded that oral and maxillofacial surgeons must be prepared in knowledge and skill for such emergency care.

Purpose: Generally, aspirin is used as a protective agent against thrombogenic phenomenon after pulmonary valve replacement (PVR) using a bioprosthetic valve. However, the appropriate duration of aspirin use is unclear. We analyzed the impact of postoperative duration of aspirin use on the longevity of bioprosthetic pulmonary valves in patients who underwent repair for congenital heart diseases. Methods: We retrospectively reviewed the clinical data of 137 patients who underwent PVR using a bioprosthetic valve between January 2000 and December 2003. Among these patients, 89 were included in our study and divided into groups I (${\leq}12$ months) and II (>12 months) according to duration of aspirin use. We analyzed echocardiographic data from 9 to 11 years after PVR. Pulmonary vale stenosis and regurgitation were classified as mild, moderate, or severe. Results: The 89 patients consisted of 53 males and 36 females. Their mean age was $14.3{\pm}8.9$ years (range, 2.6-48 years) and body weight was $37.6{\pm}14.7kg$ (range, 14-72 kg). The postoperative duration of aspirin use was $7.3{\pm}2.9$ months in group I and $32.8{\pm}28.4$ months in group II. However, no significant difference in sex ratio, age, body weight, type of bioprosthetic valve, and number of early redo-PVRs. In the comparison of echocardiographic data about 10 years later, no significant difference in pulmonary valve function was found. The overall freedom rate from redo-PVR at 10 years showed no significant difference (P=0.498). Conclusion: Our results indicated no benefit from long-term aspirin medication (>6 months) in patients who underwent PVR with a bioprosthetic valve.
