Patient with Kawasaki disease who presented with acute myocardial infarction in young age Although the clinical course of Kawasaki disease is self limiting, coronary aneurysm or myocardial disorders develop in about 20% of the patients. In recent years there have been reports of ischemic heart disease as sequelae of Kawasaki disease in adults, especially young adults. In Korea, there was only one case report in 1995. We report a young woman who presented as acute myocardial infarction with coronary artery aneurysms which highly suggest the underlying Kawasaki disease. The acute myocardial infarction in this patient seems to be the late cardiologic sequelae of Kawasaki disease, which has been silent clinically until the presentation as an acute myocardial infarction. New noninvasive diagnostic tests are being tried to improve the detection of coronary artery complication. However, coronary angiography is still widely used to determine the presence of coronary artery lesions and access the feasibility of coronary intervention. Another advantage of coronary angiography is that, it is possible to analyze the shape and the size of aneurysm and predict the prognosis. In this case we performed the percutaneous transluminal coronary angioplasty(PTCA) instead of surgery. Further study comparing surgery with percutaneous coronary angioplasty is needed.

To evaluate the neurologic and functional improvement of anterior decompression and fusion in patients with cervical spin injury, the clinical records and x-rays of 17 patients who were treated at Gyeong-Sang National University Hospital between January 1989 and December 1993 were analyzed. The results were as follows 1. There were complete injuries of the cord in six cases, incomplete injuries in nine and nerve root injuries in two. All the patients were treated using anterior decompression and autogenous iliac bone graft with cervical plate fixation within 7 days after trauma. 2. The average time lapse from the operation to radiological union was 9.2 weeks(range;7–14 weeks). 3. The prognosis for neurologic recovery mainly depends on the severity of the initial neurologic status. The recoveries of neurologic deficit were complete in four cases, partial in ten and none in three. The motor index improved from 45.6 to 64.6 and the modified Barthel index was 71.2 points at the last follow-up. 4. The clinical results were excellent in nine cases, good in three, fair in two and poor in three. In conclusion, anterior decompression and fusion with bone graft and cervical plate provided early mobilization and rehabilitation, and improved neurological function in a considerable portion of the patient who had neurologic deficits after cervical spine injuries.

PURPOSE: The purpose of this study was to understand the meaning of experiences in home visiting nursing service among the elderly in community provided by nursing students. METHOD: This is a phenomenological study to investigate the experience of community-based patients. Data were collected through in-depth interviews from the 4th of March to the 15th of December 2003. Individual interviews were conducted with 8 patients on subjective experiences. Data were analyzed through Colaizzi's method, in which meaningful statements were extracted. RESULT: Four categories were identified from nine theme clusters. The four categories were 'thankfulness', 'dependence', 'sorrowfulness' and 'the sense of being'. CONCLUSION: These results show the importance of visiting nursing service for the elderly in community.

The thoracic and lumbar spine fractures were usually combined with neurological deficit. But the prognostic factors in degree of neurological damage and process of the recovery are controversial. The purpose of this study is to evaluate the factors affected neurological injury and the recovery. The 31 cases who had been performed surgical interventions due to traumatic thoracic or lumbar spine fractures with the neurological deficits were studied according to the radiographic findings of the spinal columns and neurological changes of the injured cord and/or the roots. The duration of mean follow-up was 32.6 months, and all cases were evaluated by motor index score and Frankel grade. Total cases were divided into complete paralytic (N=8) and partial paralytic(N=23) group. In incomplete paraplegia group, the neurological recovery rate was better than complete group(P < 0.001) and neurological recovery period was shorter than complete group (P=0.005). The neurologic deficits according to the Frankel grade were higher in Chance fracture, flexion-distraction and translation (complete paraplegia: 4/7 cases, 57.1%) than unstable bursting fracture (complete paraplegia: 4/24 cases, 16.7%)(P=0.031). The recovery rate of Chance fracture, flexion-distraction and translation were worse than unstable bursting fracture (0.001). The fracture which occurred in T5-11 showed higher incidence of complete paraplegia(75%) compared with that of the T12-L1(30.8%) & L2-4(7.1%)(p=0.021). The neurological recovery in motor index score in L2-4 was higher than T5-11 or T12-L1(P=0.0017). There was no correlation in kyphotic deformity and anterior body height loss between complete and incomplete paraplegia groups. But the A-P diameter of compromised neural canal showed significant difference between complete and incomplete paraplegia group(P=0.027)

OBJECTIVES: This study was to investigate the fertilization rate after intracytoplasmic sperm injection (ICSI) or partial zona dissection (PZD) of human and hamster sperm into hamster oocyte in in vitro fertilization (IVF). In addition, the possibility of clinical application was evaluated by the comparison of usefulness and difference of these method. MATERIALS AND METHODS: Hamster immature oocytes were obtained from oviducts superovulated by PMSG and hCG, and hamster sperms were obtained from epididymis. The freezed human sperms were thawed before use. Fertilization were confirmed by two pronuclei, one pronucleus, swollen sperm head or/and two polar bodies at 7~8 hour after ICSI or PZD. RESULTS: The fertilization rates after ICSI and PZD of human sperm to hamster oocyte were 3.6%, 64.2%, 73.6%, and 55.6% for negative control, positive control, ICSI, and PZD respectively, suggesting that ICSI only showed improved fertilization rate (p<0.01). The fertilization rates after ICSI and PZD of hamster sperm to hamster oocyte were 11.1%, 51.2%, 39.6%, and 72.7% for negative control, positive control, ICSI, and PZD respectively, suggesting that PZD only showed improved fertilization rate (p<0.01). PZD showed significantly higher fertilization rate than ICSI (p<0.05). CONCLUSIONS: As for the fertilization rate by ICSI and PZD using hamster oocyte in IVF, ICSI technique was considered to be more useful for human sperm and PZD technique for hamster sperm. Therefore, ICSI technique was considered more appropriate for experimental application using human sperm and hamster oocyte.

OBJECTIVES: This study was carried out to evaluate the effects of embryonic stage, cryoprotectant, and freezing-thawing method on the rates of survival and development of the cryopreserved mouse early embryo and finally to establish the cryopreservation method of surplus embryos obtained during assisted reproductive technology (ART). MATERIALS AND METHODS: Two to eight cell embryos were obtained from oviducts of mated F1 hybrid female mice superovulated by pregnant mare's serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Two-step 1,2-propanediol (PROH), dimethylsulfoxide (DMSO) and 4-step PROH, DMSO were used as cryoprotectant and dehydration and rehydration method of embryos, and slow- cooling or rapid-cooling method was used as frozen program. The survival rates of embryos were measured after thawing and rehydration, and the developmental rates of embryos were compared and observed during culturing embryos for 24, 48, 72, 96 hrs. RESULTS: As for the survival and development rates of embryos according to embryonic stage, the survival rate of 2 cell stage in PROH and DMSO was significantly higher than 4-8 cell (64.5% versus 62.1%, 79.7% versus 73.2%) (p<0.01, p<0.01), but the development rates of 4-8 cell embryos in PROH and DMSO were significantly higher than 2 cell embryos for whole culture period (p<0.01) and the development rates of 4-8 cell embryos in PROH were significantly higher than 2 cell embryos in DMSO (p<0.01). As for the survival and development rates of embryos according to cryoprotectant, the survival rate of 2 cell embryo in DMSO was significantly higher than that in PROH (74.4% versus 64.5%) (p<0.01), whereas the development rate of embryos was not differ till 24 hrs. The development rate from morular to hatching blastocyst, however, was significantly higher in PROH than in DMSO during 48 hr (p<0.01). The survival rate of 4-8 cell embryo was 62.1% in PROH and 73.2% in DMSO. The development rates of embryo in PROH were significantly higher for whole culture periods (p<0.01, 0.05). In respect to the effect of freezing and thawing program on the survival and development rates of embryos, method of slow cooling and rapid thawing was more effective than that of rapid cooling and rapid thawing. CONCLUSIONS: The survival rate of embryo in 2 cell stage was higher than in 4-8 cell stage, and PROH appears more effective cryoprotectant than DMSO because PROH showed better development rates of embryos in 2 and 4-8 cell stage. Moreover, slow cooling and rapid thawing method was considered as the best cryopreservation program.
