To investigate the mechanism of crescent formation, sequential pathologic changes from the New Zealand White rabbits with anti-GBM antibody induced GN by administration of guinea pig anti-GBM IgG were studied by light (LM), immunofluorescent (IF) and electron (EM) microscopy. Although no glomerular changes were observed in LM, swelling of the endothelial cells and the epithelial cells were noted in EM by day 2. By day 7, early and cellular crescents were evident. Proteinaceous materials and fibrins were noted in the glomerular capillary lumina (GCL) and Bowman's space (BS) associated with segmental hypercellularity. The GBM damage became progressively severe, followed by focal detachment of the visceral epithelial cells from the GBM. At day 14, fibrin strands, mononuclear cells and collagen fibrils were present between the proliferating extracapillary cells. At day 31, fibrocellular crescents were predominated. Elongated spindle cells, morphologically resembling myofibroblasts, were noted near the Bowman's capsule (BC). A degree of tubular atrophy, interstitial fibrosis, and inflammatory infiltrates increased as it did with fibrous organization of crescent. Intense linear IF staining for IgG and C3 were seen throughout the experiments along the GBM. In conclusion, the progression of crescent from an early "proteinaceous" stage through cellular, fibrocellular and fibrous stages was well documented in this study. Inflammatory cells and coagulation mechanism may activate the initiation of the GBM damage at the early stage. Activated periglomerular mononuclear cells may also cause disruption of BC which facilitates entry of activated periglomerular cells and fibroblasts into BS leading to progressive fibrous crescent formation.

2.An Analysis of Interrupting Factors in Collaboration between Medical Professionals in Home Health Service.
Journal of Korean Academy of Nursing 2000;30(7):1729-1742
The propose of this study is to give a theoretical basis for better home health service by looking at the subjective structure the collaboration between the home health nurse and doctor and at how collaboration can be improved. There are at least three types of recognition that can help the collaboration. The first type is to put more weight on the relationship between doctors and home health care nurses. This means that doctors and home health care nurses should make an effort to improve, their collaboration. The second type is to put more weight on the reward for doctors' participation. Reward will help collaboration. The third type is to put more weight on organization support. Organization support will bring about trust between doctors and home health care nurses The following conclusion were reached: 1) Trust should exist between doctors and home health care nurses. 2)Doctors should maintain an equal relationship with home health care nurses and accept them as professionals. 3) Appropriate reward should be given to doctors for their participation. 4)Home health care nurses should reinforce their skills through education, training, and professionalization. 5) Home health care nurses should cooperate with doctors by building a system that centers on patients. 6) Collaboration between doctors and home health care nurses is important because it is useful to recognize patients and their families in a broader light. 7) Doctors and home health care nurses need to be more concerned about patients. 8)More active support of hospital administrators and systems is needed to enhance collaboration between doctors and home health care nurses. 9) The present legal system for collaboration between doctors and home health care nurses can be a factor. The nine nursing strategies above will help doctors and home health care nurses build more positive relations and get closer to their patient, more effective home healthcare will get closer to people who want quality medical service.

Intrathecal administration of methotrexate(IT-MTX) has constituted the standard approach to prophylaxis and treatment of central nevous system(CNS) leukemia. We experienced a quadriplegia and motor aphasia in a 14-year-old boy following repeated IT-MTX for the prophylaxis of meningeal leukemia. He was diagnosed as ALL without CNS involvement and treated by CCG- 1882 protocol. IT-MTX was administered for CNS prophylaxis. The patient began complaining of urinary incontinence, motor aphasia and weakness in his right leg from 12 days after the 5th dose of the IT-MTX therapy. Even though the IT-MTX was discontinued, loss of muscle power progressed upward resulting in quadriplegia. The patient showed slow and partial recovery on right extremities over 3 months. We report this case with brief review of literature.

PURPOSE: This study was conducted from January to March, 2004 to examine the effect of telephone follow-up on the performance of self-care in cancer patients undergoing chemotherapy and on role stress of family caregivers. METHOD: Research design was a nonequivalent control group non-synchronized design. Seventy-two participants were assigned to either the experimental group (18 cancer patients, 18 family caregivers) or the control group (18 cancer patients, 18 family caregivers). Data were collected before and after the intervention and were analyzed with paired t-test, t-test, Mann-Whitney U Test & Wilcoxon Signed Ranks Test. RESULTS: Performance of self-care in the experimental group undergoing telephone follow-up was significantly higher than that of the control group (t=8.016, p=0.000). Role stress of family members in the experimental group was also significantly higher than that of the control group (t=2.133, p=0.042). CONCLUSION: This results suggest that the telephone follow-up is effective for cancer patients undergoing chemotherapy and their family caregivers. Telephone follow-up can be recommended as an effective nursing intervention for self-care performance in cancer patients undergoing chemotherapy and to reduce role stress of family caregivers.

BACKGROUND: Recurrent, often unpredictable, migraine attacks significantly interfere with daily functioning and productivity of patients with migraine. Quality of life measurement represents an important tool for evaluating migraine therapy and judging the impact of headache either on individuals or on society. The objective of this study was to test the reliability and validity of the translated version of MSQoL (Migraine-Specific Quality of Life) in Korean migraine patients. METHODS: Participants, migraineurs from the Samsung Medical Center Migraine Clinic, were screened using the International Headache Society migraine criteria prior to enrollment through direct interview. This survey included the MSQoL, MIDAS (Migraine Disability assessment) and STAI (State-Trait Anxiety Inventory). RESULTS: Sixty-five migraineurs were recruited. For the MSQoL, Cronbach's alpha was 0.93. Frequency and number of accompanying symptoms were predictive of the MSQoL. The negative correlation between the MSQoL scores and the MIDAS score was seen (r=-0.585, p<0.01). Similarly a negative correlation between the MSQoL scores and duration of headache was also observed (r=-0.38, p<0.01). Although a significant negative correlation between the MSQoL and STAI scores was present (r=-0.47, p<0.01), correlation between the MIDAS and the STAI scores was not significant. CONCLUSIONS: The MSQoL is a reliable and valuable migraine-specific quantitative tool to assess the degree of quality of life in Korean migraineurs. It has a potential to provide valuable information on migraineur's disability and anxiety level. The MSQoL has acceptable psychometric properties and can be used to estimate long-term outcome of migraine therapy in Korean population.

OBJECTIVE: To determine the incidence of embryo retention (ER) in the transfer catheter following embryo transfer (ET) in blastocyst transfer and investigate whether retransferring retained embryos has an impact on reproductive outcomes in patients undergoing in vitro fertilization-ET. METHODS: We retrospectively analyzed the records of 1,131 blastocyst transfers, which comprised 223 single blastocyst transfer (SBT) and 908 double blastocyst transfer (DBT) cycles. Each SBT and DBT group was classified depending on whether ET was performed without retained embryos in the catheter during the first attempt (without-ER group) or whether any retained embryos were found following ET (ER group) for the purpose of comparing reproductive outcomes in a homogenous population. RESULTS: The overall incidence of finding retained embryos was 2.8% (32/1,131). There were no retained embryos in SBT cycles. In DBT cycles, implantation rates (30.0% vs. 26.6%), positive β-hCG rates (57.2% vs. 56.2%), clinical pregnancy rates (45.3% vs. 46.9%), and live birth rates (38.9% vs. 43.8%) were not significantly different between the without-ER and ER groups. There were no significant differences in the mean birth weight (g) 2,928.4±631.8 vs. 2,948.7±497.8 and the mean gestational age at birth (269.3±17.2 days vs. 264.2±25.7 days). A total of nine cases of congenital birth defects were found in this study population. Eight were observed in the without-ER group and one in the ER group. CONCLUSION: Our results suggest that retransfer of retained embryos does not have any adverse impact on reproductive outcomes in blastocyst transfer cycles. Furthermore, our results support finding that SBT might be advantageous for decreasing the incidence of retained embryos in catheters.

PURPOSE: Alternative medicine(AM) is defined as the approaches and techniques that are not included in the curricula of medical schools or residency training at present. This study aimed to evaluate the present status of the use of AM in allergic diseases and to propose an appropriate guide. METHODS: Mailed questionnaires on the patterns of the use of AM were collected during the month of May in 2001. The data was analyzed using SPSS WINDOW 8.0. RESULTS: 1) One hundred and five patients responded. Their mean age was 46.5 years old and the mean duration of the diseases was 67 months. 2) Ninety six(91.4%) out of 105 responders who have allergic diseases experienced AM. Herb medicine(57.3%) was most popular and hot spring(22.9%), immune stimulants(22.9%), nutritional supplements(13.5%), acupuncture(12.5%), breathing exercise, aroma-therapy and foods such as aloe, honey and ginkgo nuts were also tried. 3) The annual mean expenditure for the AM was about 690,000 Won. Severely diseased patients spent more money out of their pocket for AM. 4) Doctors(43.5%), oriental doctors(19.8%), neighbours(27.1%) and mass media played some roles for the distribution of the information about AM. 5) The patients purchased the products for AM from drug store, hospital, market, health care shop and by mail or internet orders. 6) Thirty two patients(33.3%) were satisfied with the AM and 35(36.5%) patients answered that they would recommend the AM to the others. CONCLUSION: Many allergy patients used various kinds of AM without any guidelines. Therefore, doctors' active participation in AM is necessary to confirm the scientific basis, to strengthen patient's education and to filter the informations about AM spreaded by the mass media.

Percutaneous mitral balloon valvuloplasty (PMBV) is the treatment of choice for mitral stenosis. Only a few reported cases have been reported in PMBV patients worldwide. In this study, a case of a 34 year-old female with infective endocarditis a year after PMBV is presented. The patient presented with fever, and peripheral vascular symptoms. Transthoracic echocardiography showed vegetation on the anterior mitral leaflets and Staphylococcus Viridans was isolated from blood cultures. The patient was successfully treated with Amoxicillin + Clavulate and Gentamicin. Further studies on the correlation between PMBV and infective endocarditis are needed.

Ameloblastoma is the most common odontogenic tumor of the jawbones, but the origin of this tumor has been remained to be unproven. Cytokeratins (CKs) are specific intermediate filament of epithelial cells, and vimentin is expressed in mesenchymal cells. The immunohistochemical detection of different CKs and vimentin has made it easier to know the origin of tumor. Paraffin-embedded tissue sections from 15 ameloblastomas and 1 ameloblastic carcinoma were used for immunohistochemical evaluation of CK 7, 8, 13, 14, 19 and vimentin. Their expression is evaluated in different tumor cells, which are observed in different type of tumors. In the follicular and reticular subtype, central stellate cells of tumor nests expressed CK 8, 14, 19 and peripheral columnar cells expressed CK 14. CK 7, and 13 were not expressed. Vimentin was detected in fibrous stroma around tumor nest, not in tumor cells. The tumor cells of ameloblastic carcinoma expressed CK 7, 14 and 19, but CK 8 was more weakly stained than that in ameloblastoma. Central stellate cells and peripheral columnar cells of acanthomatous subtype showed same expression pattern with others. Meta plastic squamous cells expressed CK 8, 14, 19 and keratinizing squamous cells expressed CK 13, 19. CK 7 and vimentin were not detected in tumor cells and vimentin was expressed in fibrous stroma. Most of the tumor cells of ameloblastoma showed CK 14 and CK 19 and did not express CK 7 and vimentin. These findings were similar to the immunophenotype of dental lamina. And these results will be beneficial to differential diagnosis of odontogenic tumors and other kind of tumors arising at the oral cavity.
