Purpose: To examine the effect of back massage on immune response, symptom distress, and mood state of patients undergoing allogeneic hematopoietic stem cell transplantation (allogeneic HSCT). Methods: Subjects were thirty-seven patients undergoing sibling allogeneic HSCT (including 16 in the experimental group and 21 in the control group). Experimental subjects participated in an intervention group of back massage for 10 minutes, once a day and 5 times a week, from one week prior to the HSCT to the third week after the HSCT or a control group. A non-equivalent pretest-posttest design was used. t-test and Repeated measures ANOVA were used to examine group differences by using SAS. Results: No significant group differences were found in Immune response (CD4+, CD8+,CD19+, CD56+) and symptom distress. The experimental group had significantly less mood state (anxiety, confusion) than the control group. Conclusion: The back massage for the patients undergoing allogeneic HSCT may be effective in altering the anxiety and confusion during hematopoietic stem cell transplantation. However, this study did not provide evidence in improving immune response and symptom distress.

Purpose: This study was performed to identify the pre-and post-transplant nutritional assessment for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Methods: The subjects of this study were 25 patients undergoing allogeneic HSCT. The data collection was performed from January 31st to March 31st, 2011. The Patient-Generated Subjective Global Assessment (PG-SGA), anthropometrics and biochemical test were collected from the time they entered the isolation unit until they left. Results: Pre-transplant nutritional assessment status indicated moderate malnutrition which scored $7.32{\pm}1.68$ in PG-SGA. There were 22 patients (88.0%) with moderate malnutrition and 3 patients (12.0%) with severe malnutrition. Post-transplant nutritional assessment indicated severe malnutrition status which scored $11.92{\pm}3.26$ in PG-SGA. Pre-and post-transplant nutritional assessment displayed significant differences (p<.001) in PG-SGA score. Hematopoietic stem cell transplantation led to a deterioration of patients' nutritional status. Pre-transplant patients were already in malnutrition status and patients undergoing allogeneic HSCT were at risk for malnutrition. Conclusion: Pre-and post-transplant patients were categorized as having undernutritional and malnutritional status. Pre-transplant nutrition status impacted on post-transplant nutritional status. Health care personnel should pay attention to patient's nutrition status when undergoing allogeneic HSCT with appropriate nutritional assessment tools.

The ethylacetate soluble fraction of Panax ginseng extract, which has been reported to exhibit hematopoietic effect, was divided into three subfractions, i.e., Fr. I, Fr. II and Fr. III by silica gel column chromatography. The hematopoietic effect of each subfraction was examined in rats treated with anticancer agent, Ara-C($1-{\beta}-D-arabinofuranosylcytosine)$). Among them, Fr. III showed 90% recovery of leucocyte and erythrocyte counts in bonemarrow cell depleted rats, suggesting it to be hematopoietic fraction. From Fr. III, two major compounds were isolated and identified as ginsenoside $Rh_1$ and $Rg_2$ by $^{13}C-NMR$ and degradation method.

Salmonella typhimurium, causing mouse typhoid, infects hosts such as macrophage cells, and proliferates in intracellular vacuoles causing infected cells to trigger numerous genes to respond against the infection. In this study, we tried to identify such genes in RAW264.7 cells by using the PCR screening method with degenerate primers. Fourteen genes were found to be differentially expressed after a 4 h infection in which the expression of 8 genes increased while expression of the others decreased. Most of the genes were involved in proinflammatory responses such as cytokines production and cell death. The mutation in msbB gene encoding the myristoyl transferase in lipid A of lipopolysaccharide (LPS) resulted in much lower toxicity to the inoculated animals. We compared the expression of the identified genes in wild-type and msbB-mutated S. typhimurium infections and found that Lyzs encoding lysozyme type M was differentially expressed. This gene is quite likely to be related to bacterial survival in the host cells.

Infectious hematopoietic necrosis virus (IHNV) is s significant viral pathogen affecting cultured rainbow trout (Oncorhynchus mykiss) in Korea. In this study, five monoclonal antibodies (mAbs) (IHNV-1, 2, 3, 4, and 5) were produced using purified IHNV. Reactivities of these mAbs were analyzed by western blot (WB), enzyme-linked immunosorbent assay (ELISA), and indirect fluorescent antibody test (IFAT). These mAbs recognized glycoprotein (69 kDa, IHNV-1), nucleocapsid protein (39 kDa, IHNV-3, 4, and 5), or phosphoprotein (27 kDa, IHNV-2) of IHNV by WB analysis. ELISA results indicated that these five mAbs were specific to IHNV without showing any cross-reactivity against other fish viruses (hirame rhabdovirus, infectious pancreatic necrosis virus, and viral hemorrhagic septicemia virus). IFAT demonstrated specific fluorescence signals of IHNV-infected epithelioma papulosum cyprini (EPC) cells, whereas no reactivity of normal EPC cells was observed. These mAbs can be very useful for immuno-diagnosis of IHNV infection.

Objectives : Acording to the fact that Juakium has been frequently used in a lot of prescriptions to tonify bone marrow, We examined the hematopoietic effects of Juakium-derivative on aplastic anemia. Methods : After C57BL/6 mice were oral administrated with Juakium-derivative and injected with benzene, we counted the number of WBC, RBC, hemoglobin, platelet, nucleated cells and other erythroid parameters and weighed the spleen. Also we measured the expression of $CD34^+$ cell activity and analyzed the bone marrow tissue and spleen tissue histologically. Results : The results are summerized as follow: 1. The Juakium-derivative plus benzene group showed the improvement in the number of WBC, RBC, hemoglobin. platelet, nucleated cells and other erythroid parameters, compared with the benzene only group. 2. The spleen weight and the percent of $CD34^+$ cell of Juakium-derivative plus benzene group was higher, compared with the benzene only group. 3. The bone marrow tissue and spleen tissue of the Juakium-derivative plus benzene group showed the decrease of the infarcted area compared with the benzene only group. Conclusions : These results suggest that Juakium-derivative has hematopoietic effects on aplastic anemia induced by benzene through increasing the blood cells and stimulating the activity of $CD34^+$ cells. Therefore it is expected that Juakium-derivative can be used clinically to the patient with hematopoietic system disorder.

Despite the improvements in supportive care, early and late hematopoietic stem cell transplantation-related complications still remain a significant cause of morbidity and mortality. Pulmonary complications occur in 40-60% of patients who undergo allogeneic hematopoietic stem cell transplantation. Late-onset noninfectious pulmonary complications can occur months and even years after transplantation. Interstital lung disease has also been reported to be a late post-transplant complication. Exposure to cytotoxic drugs and/or irradiation has been implicated as a cause of pulmonary toxicity including pulmonary fibrosis. We report a case of an 18-year-old female with non-classifiable interstitial pneumonia that manifested eight and a half years after allogeneic hematopoietic stem cell transplantation. The condition worsened rapidly and the patient eventually died.

Objectives: This systematic review addressed the question: "What is the prevalence of apical periodontitis in patients prior to hematopoietic cell transplantation?" Materials and Methods: A systematic search was conducted in MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Grey Literature Report. Eligibility criteria were based on the condition, content, and population strategy: the condition was the radiographic prevalence of apical periodontitis, the content comprised patients scheduled for hematopoietic stem cell transplantation, and the population consisted of adult and pediatric patients. The revised Risk of Bias in Nonrandomized Studies of Exposure tool was used to assess the quality of studies. The Grading Recommendations Assessments, Development, and Evaluation (GRADE) tool was used to assess the quality of evidence. Results: Eight studies were included in this review. The average number of patients with apical periodontitis was 15.65% (range, 2.1%-43.34%). One study was classified as having a very high risk of bias, 1 with a high risk of bias, and 6 with some concern for bias. GRADE analysis showed a very low certainty of evidence. Significant limitations concerning the absence of control over confounding variables were identified. Conclusions: With the caveat of the very low quality of evidence in the studies reviewed, there was a low to moderate prevalence of apical periodontitis in patients prior to undergoing hematopoietic cell transplantation.

Objective : Increasing in frequency and success of hematopoietic stem cell transplantation and improved survival rates have led to growing concerns regarding the psychosocial aspects of hematopoietic stem cell transplantation recipients. In this study, we have examined the stress coping strategies and related psychiatric symptom in the hematopoietic stem cell transplantation recipients. Methods : In this study, we examined the psychological stress symptoms of hematopoietic stem cell transplantation recipients and differences of psychosocial variables between active coping group and passive coping group. Twenty nine recipients of hematopoietic stem cell transplantation were recruited prospectively and assessed at 2 weeks pretranplant and at 1-2 days posttranplant. Thirty normal controls were recruited. Assessments included a psychiatric interview, a variety of standardized questionnaires (Ways of Coping Questionnaires, Perceived Stress Scale, Hospital Depression and Anxiety Scale, Short-Form 36 Health Survey). Results : Hematopoietic stem cell transplantation patients showed higher degree of depression (p<0.001) and anxiety (p=0.011) symptoms than normal control group. However, no differences of depression and anxiety symptoms between pretransplant and posttransplant status were showed. And, passive coping group showed higher degree of depression (p=0.046) and anxiety symptoms (p<0.001) than active coping group. Conclusions : Our results suggested that many hematopoietic stem cell transplantation recipients would exhibit severe to moderate symptoms of anxiety and depression. Also, it seemed likely that passive coping style might influence the development of negative affect such as anxiety and depression. The implications of these findings were discussed in terms of the need to monitor the coping strategies and apply the appropriate psychiatric intervention. And, further prospective studies about long-term survival and psychological adaptive functions of hematopoietic stem cell transplantation patients are recommended.

Human umbilical cord blood was stored at $4^{\circ}C$ in the Pluronic-immobilized flask as well as commercially available bio-inert flasks, and flow cytometric analysis of surface markers was performed on hematopoietic stem cells after cultivation. The number of cells expressing $CD34^{+}$ in umbilical cord blood on the Pluronic-immobilized flask was extremely higher than those obtained using other flasks. It is concluded that the flexible and hydrophilic segments of Pluronic conjugated on the flask surface are the reason for the effective preservation of hematopoietic stem cells in the Pluronic-immobilized flask.
