Purpose: The purpose of this study was to identify the effects of an individual educational program on self-care knowledge and self-care behavior in kidney transplantation patients. Methods: The kidney transplantation patients were recruited from a transplantation center, at a university hospital located in Korea. Data were collected from June 1, 2010 to January 31, 2011. The research design was a nonequivalent one group pre-post test. Forty-two subjects were participated two times individually in an educational program given by the researcher. Results: After the intervention, the participants showed a significant increase in self-care knowledge(t=-4.10, p=.000) and self-care behavior (t=-6.07, p=.000) than before the intervention. Conclusion: This results suggest that the program developed in this study can be considered an effective nursing intervention for health promotion, prevention of complication and self-care behavior in kidney transplantation patients.

Purpose: The purpose was to examine the self-efficacy, coping, and compliance in patients with kidney transplantation. Methods: Participants consisted of 300 outpatients who underwent kidney transplantation and regularly visited hospital for health check-up. A tool developed by Ahn (2000) was used for measuring self-efficacy. A modified version of the Jalowiec Coping Scale (Jalowiec, 1987) by Hwang (2004) was used for measuring coping, and a tool developed by Ryu, Kim, and Kang (2003) was used for compliance. Data were analyzed using SPSS program version 21.0 ANOVA, Pearson's correlation coefficient, and Scheff$\acute{e}$'s test for post-hoc test. Results: Coping shows significant differences according to marital status and education. Coping was used more often among patients with ABO incompatible transplantation than those with ABO compatible. Differences in compliance were significant according to donor type, ABO incompatible, period after transplantation, and admission after the transplantation. The management of life style, stress, nutrition, and exercise in self-efficacy and compliance had lower scores than the others. Conclusion: There are significant correlations between self-efficacy, coping, and compliance in patients with kidney transplant which might be helpful for health care professionals in taking care of these population.

Purpose: This study was done to identify the level of stress, coping, and depression among hemopoietic stem cell transplantation patients who received care in an outpatient center. Method: Data were collected from 81 patients who underwent hemopoietic stem cell transplantation at C University S Hospital between August 2005 and February 2006. Results: Stress and depression were significantly higher following hemopoietic stem cell transplantation in women, and in patients who were worse off financially or who were in bad health. The highest item of stress was 'economic burden for treatment'. There were significantly higher levels of emotion-focused coping among patients who had a spouse and who received motivation from the doctor. The highest item for problem-focused coping was 'try to look at the bright side of life'. The highest items for emotion-focused coping were to 'have faith that treatment will be finished quickly' and 'believe that your situation will improve'. Stress was significantly correlated with depression among these patients. Conclusion: It is necessary to develop nursing interventions to enhance positive coping and to decrease stress and depression among patients who have a hemopoietic stem cell transplantation.

The purpose of this study is to evaluate an efficacy of in vitro differentiated human embryonic stem (hES, MB03) cells expressing Nurr1 in relief of symptomatic motor behavior of Parkinson's disease (PD) animal models MB03 was genetically modified to express Nurr1 protein and was induced to differentiate according to 2-/4+ protocol using retinoic acid and ascorbic acid. The differentiation-induced cells were selected for 10 to 20 days thereafter in N2 medium. Upon selection, cells expressing GFAP, TH, or NF200 were 38.8%, 11%, and 20.5%, respectively. in order to examine therapeutic effects of the differentiated cells in PD animal model, rats were unilaterally lesioned by administration of 6-kydroxydopamine HCI (6-OHDA) into medial forebrain region (MFB, AP -4.4 mm, ML 1.2 mm, DV 78 mm with incision bar set at -2.4 mm), as a reference to bregma and the surface of the skull. Confirmation of successful lesion by apomorphine-induced rotational behavior, differentiated cells were transplanted into the striatum (AP 1.0, ML 3.5, DV -5.0; AP 0.6, ML 2.5, DV -4.5). Improvements of asymmetric motor behavior by the transplantation were examined every two weeks after the surgery. In two weeks, numbers of rotation by the experimental rats were $-14.8 \pm 33.9%$ (P<0.05) of the number before transplantation, however, the ratio increased slightly to $13.6 \pm 56.3%$ in six weeks. In contrast, the ratio of sham-grafted animals ranged from 112.3+8.5% to 139.2+28.9% during the examination. Immunohistochemical studies further confirmed the presence, survival, migration, and expression of TH of the transplanted human cells.

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.

Purpose: Many trials for new therapeutic approaches such as stem cell-based transplantation have been conducted to improve the repair and regeneration of injured cord tissue and to restore functions following spinal cord injury (SCI) in animals and humans. Adipose tissue-derived stromal cells (ATSCs) have multi-lineage potential to differentiate into cells with neuron-like morphology. Most studies of stem cell transplantation therapy after SCI are focused on cellular regeneration and restoration of motor function, but not on unwanted effects after transplantation such as neuropathic pain. This study was focused on whether transplantation of ATSCs could facilitate or attenuate hindpaw pain responses to heat, cold and mechanical stimulation, as well as on improvement of locomotor function in a rat with SCI. Methods: A spinal cord injury rat model was produced using an NYU impactor by dropping a 10 g rod from a height of 25 mm on to the T9 segment. Human ATSCs (hATSCs; approximately $5{\times}10^5$ cells) or DMEM were injected into the perilesional area 9 days after the SCI. After transplantation, hindpaw withdrawal responses to heat, cold and mechanical allodynia were measured over 7 weeks. Motor recovery on the Basso, Beattie, and Bresnahan (BBB) locomotor rating scale and on the inclined plane test were also evaluated. Results: The present study demonstrated that increased hindpaw withdrawal responses to cold allodynia was observed in both groups after transplantation, but the development of cold-induced allodynia in the hATSC transplantation group was significantly larger than in the control group. The difference between the two groups in locomotor functional improvement after SCI was also significant. Conclusion: Careful consideration not only of optimal functional benefits but also of unintended side effects such as neuropathic pain is necessary before stem cell transplantation therapy after SCI.

Purpose: The purpose of this study was to test a hypothesis explaining direct and indirect relationships among the factors affecting self-care behaviors of kidney transplant patients, based on self-determination theory. Methods: Data were collected from 222 outpatients with kidney transplantation. The endogenous and exogenous variables of the hypothetical model consisted of healthcare provider's autonomy support, duration after kidney transplantation, basic psychological need satisfaction, autonomous and controlled motivation, depression, and self-care behaviors. Collected data were analyzed using SPSS/WIN 24.0 and AMOS 24.0. Results: The hypothetical model demonstrated a good fit: RMSEA=.06, SRMR=.04, TLI=.94, CFI=.97. Statistically significant explanatory variables for the self-care behaviors of kidney transplant patients were duration after transplantation and basic psychological need satisfaction. Healthcare provider's autonomy support was indirectly significant, while autonomous motivation, controlled motivation and depression were not statistically significant for self-care behaviors. The variables accounted for 59.5% of the self-care behaviors of kidney transplant patients. Conclusion: It is necessary to develop an autonomy support program for healthcare providers to enhance the self-care behaviors of kidney transplant patients. Preventing the deterioration of self-care behaviors will be possible by conducting this program at one year and six years post-transplantation. In addition, the results suggest the need to developing personalized autonomy support programs for healthcare providers that can meet the basic psychological need satisfaction of kidney transplant patients.

The effects of fetal mesencephalic cell grafts on the restoration of nigrostriatal dopaminergic function were studied in the intrastriatal 6-hydroxydopamine-lesioned rats. Four weeks after lesioning, transplantation of ventral mesencephalic cells from embryonic day 14 fetuses showed the number of tyrosine hydroxylase (TH) positive cells and fiber outgrowth in the grafted striatum, and significantly ameliorated symptomatic motor behavior of the animals, as determined by apomorphine-induced rotation. Furthermore, in substantia nigra pars compacta (SNc), the numbers of TH + cells and fibers were markedly restored. Dopamine content of ipsilateral SNc was close to that of contralateral SNc $(91.9{\pm}9.8%)$ in the transplanted animals, while the ratio was approximately 32% in sham-grafted animals. These results indicate that grafted cells restored the activity for the dopaminergic neurons located in SNc, although they were transplanted into striatum. In addition, we showed that the implanted fetal cells expressed high level of glial cell line-derived neurotrophic factor (GDNF), suggesting that the transplanted fetal cells might serve as a dopamine producer and a reservoir of neurotrophic factors. These results may be helpful in consideration of the therapeutic transplantation at early stage of PD.
