PURPOSE:Several drugs such as insulin, propranolol, levodopa, glucagon and clonidine have been used for pharmacological growth hormone(GH) provocative test, and each medical center chooses different combinations of drugs during GH provocative tests. In this study, authors compared three drugs insulin(RI), clonidine(C), and propranolol-levodopa(P-L) in terms of GH secretory ability to select the most effective drug. METHODS:Study patients consisted of 63 children with idiopathic growth hormone deficiency, who were diagnosed 'H deficiency'in the department of pediatrics, Kyungpook National University Hospital between January, 1995 and December, 1995. Peak values of GH by each drug were analyzed and following results were obtained. RESULTS:Numbers of patients who showed peak GH values of < or = 5ng/mL, 6-9ng/ mL or > or = 10ng/mL were 23, 22 and 18 respectively in GH provocative test using RI, 48, 12 and 3, respectively in GH provocative test using P-L, 55, 8 and 0, respectively in GH provocative test using C. The numbers of patients showing peak growth hormone values over 6ng/mL were more significantly in GH provocative test using RI than those using P-L or C(P<0.05). CONCLUSION: Among drugs authors have been using in GH provocative tests, RI was more effective in stimulating growth hormone secretion than P-L or C. Authors feel that RI should be included in GH provocative tests for the diagnosis of growth hormone deficiency.

PURPOSE: This study was done to examine the relation of uncertainty, uncertainty appraisal, and self-management in patients undergoing hemodialysis, and to identify factors influencing self-management. METHODS: A convenience sample of 92 patients receiving hemodialysis was selected. Data were collected using a structured questionnaire and medical records. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlations and multiple regression analysis with the SPSS/WIN 20.0 program. RESULTS: The participants showed a moderate level of uncertainty with the highest score being for ambiguity among the four uncertainty subdomains. Scores for uncertainty danger or opportunity appraisals were under the mid points. The participants were found to perform a high level of self-management such as diet control, management of arteriovenous fistula, exercise, medication, physical management, measurements of body weight and blood pressure, and social activity. The self-management of participants undergoing hemodialysis showed a significant relationship with uncertainty and uncertainty appraisal. The significant factors influencing self-management were uncertainty, uncertainty opportunity appraisal, hemodialysis duration, and having a spouse. These variables explained 32.8% of the variance in self-management. CONCLUSION: The results suggest that intervention programs to reduce the level of uncertainty and to increase the level of uncertainty opportunity appraisal among patients would improve the self-management of hemodialysis patients.

PURPOSE: This study was done to investigate factors influencing successful aging in middle-aged women. METHODS: A convenience sample of 103 middle-aged women was selected from the community. Data were collected using a structured questionnaire and analyzed using descriptive statistics, two-sample t-test, one-way ANOVA, Kruskal Wallis test, Pearson correlations, Spearman correlations and multiple regression analysis with the SPSS/WIN 22.0 program. RESULTS: Results of regression analysis showed that significant factors influencing successful aging were post-traumatic growth and social support. This regression model explained 48% of the variance in successful aging. CONCLUSION: Findings show that the concept 'post-traumatic growth' is an important factor influencing successful aging in middle-aged women. In addition, social support from friends/co-workers had greater influence on successful aging than social support from family. Thus, we need to consider the positive impact of post-traumatic growth and increase the chances of social participation in a successful aging program for middle-aged women.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. 9 Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented.20 Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. B-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.

PURPOSE: This study was done to identify the effectiveness of CPR training for nurses in the 6-sigma course. METHOD: The participants were nurses and doctors who worked in the medical center. For data analysis, the SPSS/PC14.0 program was used. RESULT: The total 11 categories of the primary problems were revealed on the recognition of carrying out CPR by nurses and doctors. After understanding the nurses' CPR knowledge and the practical ability, the survey showed 14.97 points and 67.12 points. After the education, the scores were increased from 14.87 to 23.25 in knowledge and from 67.12 to 93.43 in practical ability. The 6-sigma problem was ended as worked up the management plan and understood the changes over the management improving team. CONCLUSION: This study carries an emphasis on understanding of various CPR performance problems applied with 6-sigma in ward. In addition, improvement activities in relation to policy of hospitals suggest the high possibilities that the application of the improvement activities could be extended into the entire hospitals.

BACKGROUND: The purpose of carotid endarterectomy is to prevent stroke regardless of past neurologic events. Major concern in the carotid endarterectomy is the inadequate blood flow of ipsilateral hemisphere during clamping of the carotid artery. It is well known that internal carotid artery back pressure means collateral cerebral blood flow. Our study is intended to determine the guideline of shunt placement according to the carotid back pressure and electroencephalographic finding. MATERIAL AND METHOD: The study population comprised of 16 consecutive patients who underwent carotid endarterectomy for carotid stenosis in our institution between from February 1996 to March 1999. There were 14 men and 2 women between the ages of 56 and 78 years(mean age 66.25+/-6.53 years). The carotid stenosis in the operative site was ranged from 61% to 95%(mean 73.8+/-12.33%) and the mean carotid stenosis of the contralateral side was 60.99+/-25.03%. During the operation, electroencephalographic monitoring was taken in all cases. The internal carotid artery back pressure was measured to estimate the collateral cerebral blood flow, and in all patients with back pressure below 40 mmHg(11 patients) and patients with complete occulusion of contralateral carotid artery(2 patients), an internal shunt was installed. RESULT: One postoperative death occurred in a patient with large evolving cerebral infarction and severe ipsilateral carotid stenosis, who underwent emergent carotid endarterectomy. The cause of death was hemorrhagic infarction in the corresponding cerebral territory. We observed that immediate operation after a major stroke negatively influenced the postoperative outcome. No intraoperative ischemic neurologic complication developed. During the follow-up upto now(mean follow-up 21.5+/-11.85 months), there has been no early or late recurrence of stroke except one patient ,in whom cerebral infarction developed in the contralateral side on the first postoperative day. CONCLUSION: At least 4-6 weeks stabilization after a stroke is recommended for surgical management. The carotid endarterectomy is an effective surgical intervention for prevention of anticipated stroke and can be performed safely if an internal shunt is used in patients whose internal carotid arterial back pressure is below 40 mmHg.

25 Patients were received major spinal surgeries at main operating theater of Kangnam General Hospital from May 1990 to December 1990 by using the Haemonetics cell saver which was employed as an intraoperative blood salvage and autologous blood transfuser. The products of washed red blood cells were an average of 1490 cc packed RBC per case. Under the Light Microscopy, Washed RBC disclosed the morphologies of normal RBC size and shape. Fragmented RBCs or cell debris were not found and in one case agglutinated and denaturated RBCs were seen. While 20 patients were received spinal surgery prior to the utilization of cell saver, an average of 7.85 units of banked whole blood was transfused compared with 5.55 units in the cases of using the cell saver (p<0.05). Homologous banked blood utilization during spinal surgery declined more than 30% with the use of the cell saver. There was no evidence of infection, renal and/or hepatic failure related to the use of the cell saver. Haemonetics cell saver appeared to be safe, efficient and more over in some instanes life saving.
