  • Nuclear transplantation techinque has been found to be the most potential and efficient method for producing a large number of genetically identical animals from a single embryo. The technical development of nuclear transplantation in mammals and its application to the production of cloned animals were reviewed. For the efficient and successful production of cloned embryos by nuclear transplantation, selection and micromanipulation of recipient eggs or embryos as capacious recipient cytoplasm, and benefitial preparation of multiple totipotent embryonic cells as donor nuclei, and also fusion technique are very critical. Recent works approaching to these critical points were introduced and discussed.

  • Sinus node dysfunction is common after orthotopic heart transplantation.Electrophysiologic studies have documented a high incidence [46% to 50%] of impaired sinus node automaticity and sinoatrial conduction in the early posttransplantation period. Sinus node dysfunction persists in over 20 % of patients and leads to prolonged bradyarrythmias, including sinus or nodal bradycardia and sinus arrest.The purpose of this paper was to observe sinus node dysfunction after orthotopic heart transplantation. Ten cardiac recipient dogs were monitored continuously after orthotopic transplantations between unrelated adult mongrel dogs. Crystalloid cardioplegic solution [Choongwoi Cardioplegia

  • This study was designed to identify the attitudes of the people on organ donation and transplantation. The purpose of this study was to provide data to help inspire organ donation, and promote registration yield so donor candidates will have more favorable recipients through Q-methodology. A Q-sample was developed through a review of the literature and interviews. Thirty-three statements made up the final Q-sample. The P-sample consisted of twenty-eight subjects, excluding chronic organic disorder. The Q-sorts by each subject were coded and analyzed with the QUNAL computer program. The results were as follows: This study discovered five different types of organ donation and transplantation of twenty- eight subjects. Type I is 'utilitarian.' The people of this type consider human life very valuable and they recognize that organ transplantation is an affirmative medicine that should be performed to extend human life. They believe that are saving others' lives by donating organs. Type II is 'sardonist.' The people of this type approve of organ transplantation usefulness, but they have no intention of participating in the program because of it may trample on human rights. Type III is 'individualist.' The people of this type consider it proper for the activation of organ transplantation by the legal system. They believe that organ donation a valuable too, but needs support through social benefits to donors. Yet, they have not intention of doing what they propose. Type IV is 'familist.' The people of this type have strong attachments to life but they think that organ donation and transplantation should be done between within a family. Type IV is disposition of family intensive consideration rather than altruistic and utilitarianism. Type V is 'deontologist.' The people of this type recognize the benefits of transplantation, but have a negative opinion of activation. They worry about ethical and social problems occurring in the development of modern medicine. They believe that death is the only natural end to life, so they have strong negative opinions of euthanasia and brain death compared to other types. They regard transplantation to be a non-human behavior, because it involves a removing organs and breaking the boundary of death. The findings of this study are only preliminary and serve as a baseline to understanding the subjectivity of individuals on organ donation and transplantation. Therefore, the subjectivity of the five types will be applied to formulate the educational programs and public relations strategies for organ donation because the public's awareness toward organ donation is closely related to their values, beliefs, and attitudes.

  • Background: The prognosis of patients with hepatocellular carcinoma (HCC) after curative resection varies greatly. Few studies had investigated the risk factors for early recurrence (recurrence-free time ${\leq}$ 1 year) of hepatitis B virus (HBV)-related HCCs meeting Milan criteria. Methods: A retrospective analysis was performed on the 224 patients with HCC meeting Milan criteria who underwent curative liver resection in our center between February 2007 and March 2012. The overall survival (OS) rate, recurrence-free survival (RFS) rate and risk factors for early recurrence were analyzed. Results: After a median follow-up of 33.3 months, HCC reoccurred in 105 of 224 patients and 32 died during the period. The 1-, 3- and 5-year OS rates were 97.3%, 81.6% and 75.6% respectively, and the 1-, 3- and 5-year RFS rates were 73.2%, 53.7% and 41.6%. Cox regression showed alpha-fetoprotein (AFP) > 800 ng/ml (HR 2.538, 95% CI 1.464-4.401, P=0.001), multiple tumors (HR 2.286, 95% CI 1.123-4.246, P=0.009) and microvascular invasion (HR 2.518, 95% CI 1.475-4.298, P=0.001) to be associated with early recurrence (recurrence-free time ${\leq}$ 1-year) of HCC meeting Milan criteria. Conclusions: AFP > 800 ng/ml, multiple tumors and microvascular invasion are independent risk factors affecting early postoperative recurrence of HCC. In addition resection appears capable of replacing liver transplantation in some situations with safety and a better outcome.

  • Heart and kidney transplantation has made great progress in the modern era. Coupled with the growing successes in individual solid organ transplantation, there has also been an increase in the number of multiple organ transplants, such as heart-kidney transplantation. This trend has been in part due to a better understanding of immunobiology, advances in surgical technique and postoperative care, and an often-common pathologic association between dual-organ failure. This pathologic course is representative for end-stage heart failure leading to secondary renal dysfunction or failure, or for end-stage renal failure as a cause for (uremic) cardiomyopathy. However, refractory cardiac failure has long been considered a contraindication to kidney transplantation. Additionally, cardiac transplantation has been denied for patients with end-stage renal disease. Over recent years, combined heart-kidney transplantation has been offered to select patients who were once denied transplantation. We report the first experience of combined heart-kidney transplantation with one year follow-up results.

  • This Research was designed to develop an instrument that can be used for measuring and analysing the degree of the quality of life of the Allogenic bone marrow transplantation survivors and to provide basic data to help them attain a better quality of life. The subjects of this study were a total of 101 people who were undergone Allogenic bone marrow transplantation and were over 100 days after transplantation. Data were collected during the period from September 3 to December 2. 2000. In Developing this instrument, the researcher established a conceptual framework based on the result of previous research, interview of patients and medical staff and researcher's experience. The scale for this instrument consisted of 51 items. Responses were obtained from the respondents through a self reporting method and each item had a possible score of 5. The collected data were analyzed using the SPSS program. The reliability of the scale was tested by Cronbach‘s alpha. For the examination of the component factors of the measuring instruments, factor analysis method was used. Examination of the difference in the quality of life as related to demographic variables was done using t-test, analysis of variance(ANOVA). For the examination of the major variables influencing the quality of life, Pearson's Correlations was used. The results were as follows: (1) The reliability of the instrument was 0.90 (Cronbach's alpha) (2) The validity of the instrument was tested by factor analysis. The result of the factor analysis of the 51 items is making up the instruments were classified into the following factor; emotional state, Interpersonal problem, physical problem, spiritual state, social problem, decrease of physical energy, physical problem-eye, physical problem-skin and mucosa, health awareness, elimination problem, worry about health, financial problem, sexual problem. (3) Demographic variables related to quality of life is the time after transplantation. GVHD experience, lose of job. Age at the transplantation, diagnosis, type of the transplantation, marital status, monthly income, educational background, sex, religion are not related to the quality of life.

  • Purpose: Liver transplantation (LT) is the best treatment for patients with end-stage liver disease and most patients with LT return to their normal life. However, pregnancy and childbirth for women with LT are less common, mainly because it is considered to be dangerous for their health. The purpose of this study was to describe how Korean women after LT experience their pregnancy and childbirth. Methods: This study was designed to explore the experiences of pregnancy and childbirth of women with LT. Data were collected by individual in-depth interviews with four women who were pregnant and gave birth following LT in 2009. All interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. Results: Four themes emerged as a result of analysis: recovery of lost feminity and marriage; fulfilling roles through pregnancy; life-risking pregnancy; and perfect family achieved by childbirth. These themes describe in detail about challenges and concerns the women with LT faced for their pregnancy and childbirth as well as many emotionally touching experiences. Conclusion: The results of this study would support health professionals to be better prepared to help women with LT for pregnancy and childbirth by providing in-depth and insightful information.

  • Family with sequence similarity 189, member B (FAM189B), alias COTE1, a putative oncogene selected by microarray, for the first time was here found to be significantly up-regulated in hepatocellular carcinoma (HCC) specimens and HCC cell lines. mRNA expression of COTE1 in HCC samples and cell lines was detected by reverse transcription-polymerase chain reaction (RT-PCR) and real-time PCR, while protein expression of COTE1 in HCC tissues was assessed by immunohistochemistry. In addition, invasion of HCC cells was observed after overexpressing or silencing COTE1. In the total of 48 paired HCC specimens, compared with the adjacent non-cancer tissues, the expression of COTE1 was up-regulated in 31 (p<0.01). In HCC cell lines, COTE1 expression was significantly higher than in normal human adult liver (p<0.01). Overexpression of COTE1 enhanced HCC-derived LM6 and MHCC-L cellular invasion in vitro. In contrast, COTE1 knockdown via RNAi markedly suppressed these phenotypes, as documented in LM3 and MHCC-H HCC cells. Mechanistic analyses indicated that COTE1 could physically associate with WW domain oxidoreductase (WWOX), a tumor suppressor. COTE1 may be closely correlated with invasion of hepatocellular carcinoma (HCC) cells and thus may serve as an effective target for gene therapy.

  • Purpose: This study was carried out to accumulate basic data for nursing intervention development by evaluating the stress and emotional status of patients and their families after receiving hematopoietic stem cell transplantation (HSCT), illucidating and analysing related factors in order to decrease the negative effects of HSCT on their emotion. Methods: Data were collected using a questionnaire to 53 HSCT patients and 50 families, who were older than 18 at tertiary-care institutions in Seoul, from January, 2000 to August, 2003. Results: There was a significant score difference in stress (t=-2.302, P<0.05). Correlation between stress and emotional status was statistically significant (r=0.486, P<0.01; r=0, P<0.05). Economical burden of cost had significant effects on stress of patients (F=4.194, P<0.05). The series of emotional status of patients without jobs were higher (T=-2.583, P<0.05). The emotional status of families were influenced by monthly income (F=4.036, P<0.05) and patients' diagnosis (F=3.088, P<0.05). Conclusion : These results suggest that the cares for families should be considered with great concern as well as the ones for patients. In addition, such factors as economical burden by medical cost, monthly income and job status should not be excluded in transplantation nursing plans.
