BACKGROUND: Recently, clinical use of fresh frozen plasma(FFP) has increased in all blood transfusion activity. But inappropriate uses of FFP may be serious problem due to adverse transfusion reactions, viral transmission, and economic aspects. The aim of this study is to justify clinical indication of FFP by receiving the inappropriate use of them. METHODS: Analyzing hospital records of 115 patients transfused with FFP at Kyung Hee Medical Center from January to April 1998, retrospectively, we investigated the purpose of transfusions, the volume of transfused FFP, and the results of pre- and post-coagulation tests. RESULTS: The most common purpose of transfusions of FFP was plasma volume replacement after surgical operation. Coagulation tests of pre- and post-transfusion were performed 85% and 47%, respectively. Fifty-seven patients(88%) transfused FFP have shown normal results in pre-coagulation tests, and the volume replacement with FFP was done inadequately in 62 cases(54%). CONCLUSION: We conclude that, in order to eliminate side effects due to inappropriate use of FFP, and protect patients, it is necessary to make guidelines of FFP transfusion, educate hospital staffs regularly, and perform pre- and post-coagulation tests routinely for the patients who need FFP transfusion.

PURPOSE: According to the statistics announced by the Ministry of Unification, the number of North Korean refugees living in South Korea has increased by 200 on average monthly in 2010. The number of refugees increased only by 300 annually until 2000. The total number of refugees as of February 2012 was 20,956. This study aims to investigate the psychobiology of the North Korean refugees who consulted psychiatric clinics among those living daily life in South Korea. METHODS: The subjects of this study were 85 North Korean refugees that consulted psychiatric clinics from January 1, 2005 to July 2011. This study obtained demographic and psychiatric information in a retrospective approach. RESULTS: Among the 85 North Korean refugees, 75 (88.2%) were females and their average age was 48 years of age. A total of 16 (18.8%) were admitted to a clinic and among the inpatients, 4 were admitted twice and two were admitted three times. As for the claimed symptoms of outpatients, insomnia was shown in 47 (55.3%) patients, headaches in 37 (43.5%), anxiety in 20 (23.5%), depression in 19 (22.4%), etc. The major symptoms represented by inpatients were insomnia in 14 (87.5%) patients, depression in 12 (75%), and headaches in 8 (50%), etc. CONCLUSION: The most frequent psychiatric symptoms of North Korean refugees living in South Korea were insomnia and headaches. It suggests that when performing psychiatric diagnosis and treatment of North Korean refugees, we have to take into consideration the fact that they claimed the physical symptoms more than the emotional ones. Also, from the aspect that most symptoms of North Korean refugees were insomnia, more profound research on sleep is required in the future.

Factor VIII inhibitors are produced during or after coagulation factor VIII (FVIII) therapy in hemophilia A patients. These inhibitors are usually detected by a modified Bethesda assay or an enzymelinked immunosorbent assay (ELISA). In this study, we used the Bethesda assay to determine the incidence of FVIII inhibitors in 75 fresh plasma samples obtained from 50 hemophilia A patients, and then used ELISA and the Bethesda assay to determine the titres of these inhibitors after the samples had been frozen and thawed. The samples from the screening Bethesda assay were centrifuged and stored at -70degrees C in accordance with the assay guidelines. Subsequently, these samples were thawed and analyzed using ELISA and the Bethesda assay. The incidence of inhibitors in hemophilia A patients was 20.0%. Among the 35 inhibitor-positive samples identified in the screening Bethesda assay, 16 were positive in ELISA while only 4 were positive in the repeated Bethesda assay. In this study, the ELISA technique showed a higher sensitivity than the Bethesda assay in the detection of FVIII inhibitors in samples that were subjected to freezing and thawing procedures; this was because the Bethesda assay could not identify the FVIII inhibitors that were degraded after freezing and thawing.

BACKGROUND: With increase of antibiotics use and invasive procedures, infections caused by multi-resistant Acinetobacter baumannii (MRAB) are increasing. Recently, we experienced the outbreak of- nosocomial infections caused by MRAB resistant to imipenem and cefoperazone/sulbactam in intensive care units (ICU) and general ward. We analyzed the clinical characteristics of the infected patients and antibiotic susceptibility of the organisms. And surveillance cultures and IRS-PCR were performed to find out the transmission route. METHODS: We collected data from physical examination and clinical records. We performed surveillance cultures of environment, patients not infected with MRAB in ICU, and hands of health care workers. RESULTS: Between November 1996 and June 1997, 49 strains of MRAB were isolated from the 26 patients hospitalized in Kangnam St. Mary' s Hospital. The lower respiratory infection (13 cases) was the most common infection and sputum was the most common sources (47.1%). All strains of MRAB showed the same genotype. In disk diffusion test, all strains were resistant to piperacillin, gentamicin, amikacin, ceftazidime, cefoperazone/sulbactam, aztreonam, imipencm, ciprofloxacin. From the surveillance cultures, the genotypically identical strains were isolated from ventilator Y-piece, the floor of ICU, and hands of health care workers. It suggested that this strain was transmitted through ventilatory device or hands of health care workers. We instructed all the health care workers to wash hands, to disinfect hospital environment completely. Since July 1997, no further case has occurred. CONCLUSIONS: Since A. baumannii could be transmitted through ventilatory devices and the hands of health care workers, it is important to wash hands and to disinfect hospital environment completely.

The influence of normal late pregnancy on insulin action and insulin secretion was studied in the Sprague-Dawley female rats. On 20th day after mating, intravenous glucose tolerance test(IVGTI) was performed in non pregnant control and pregnant rats. As results of IVGTT, glucose disappearance rate was not significantly different in both groups, but secretory response of insulin was significantly(p<0.05) increased in pregnant rat. And the ratio of insulin/ .glucose was significantly higher in pregnant rats, which means existence of insulin resistance. These insulin resistance was overcomed by increased secretory response of pancreatic insulin. Insulinogenic index( A insulin/glucose - 5 min) was highly significantly (r=0.62, p<0.01) correlated with progesterone concentration. Glycogen level and amounts of "C-glucose incorporated into glycogen after IVGTT were significantly(p<0. 05) decreased in the liver, but were not changed significantly in soleus. Glycogen synthase activity of soleus and liver was not differ significantly in the both groups. Insulin binding at varying concentrations of insulin to crude membrane of pregnant liver was not significantly different from control. In conclusions, although these pregnant rats were normal glucose tolerance due to increased secretory response of insulin, that was correlated with progesterone concentration, pregnant rat had insulin resistance. The mechanisms of insulin resistance were not related to defect of insulin binding phase and glycogen synthase, but suggest pre-receptor and/or postreceptor phase.

PURPOSE: This study was done to: (a) identify levels of emotional labor that nursing students perceived when caring for patients in the hospital during their nursing practicum, (b) examine the impact of emotional labor on burnout, and (c) identify the possible moderating effect of emotional intelligence on the relationship between emotional labor and burnout for nursing students. METHODS: A descriptive study was conducted with a sample of 171 students enrolled in a 4-year undergraduate nursing program in one university located in Korea, and had a practicum experience at least one semester before the study began. Data were collected with self-report questionnaire, and analyzed with SPSS 21.0 program, using hierarchical multiple regression. RESULTS: Mean score for emotional labor was 3.17 with a range of 1 to 5. For nursing students, emotional labor significantly affected burnout in the nursing practicum (F=15.763, p<.001), and explained 30.1% of the variance in burnout. The degree of emotional intelligence acted as a moderator on the relationship between emotional labor and burnout at significant level (F=15.345, p<.001). CONCLUSION: This research shows that nurse managers as well as nurse educators need to pay attention to nursing students' emotional labor during nursing practicum in the care units of hospitals.
