  • Purpose: Peripheral blood stem cell transplantation (PBSCT) has been widely used. The optimal time for collection is a critical factor to obtain proper counts of CD34 cell by peripheral blood stem cell collection (PBSC). The purpose of this study was to identify the factors influencing peripheral blood stem cell collection in order to figure out the more effective timing for PBSC. Method: The subjects of this study were 189 patients undergoing 3 leukapheresis from January 28, 2005 to December 31,2006. Group's characteristics, checkup opinion of pre-peripheral blood on the day of harvest & outcome of PBSC were analyzed and evaluated using SAS statistics program after grouping patients as below; group 1-CD34 cell counts $<2{\times}10^6/kg$ (n=97); group $2-2{\times}10^6/kg$ ${\leq}CD34$ cell counts $<4{\times}10^6/kg$ (n=26); group 3-CD34 cell counts ${\geq}4{\times}10^6/kg$ (n=63). Results: Based on outcome of peripheral blood stem cell according to diagnosis, acute myelocytic leukemia (AML) was 65.5% at Group 1, Lymphoma was 21.7% at Group 2 and multiple myeloma (MM) was 70.8% at Group 3. There were significant differences in CD34 cell counts according to diagnosis (p=0.00004). Type of cytokine mobilization according to diagnosis, Lenograsim was using 62.5% of MM & 38.2% of AML and filgrastim is using 22.0% of AML only. Circular peripheral blood CD34 cell counts prior to harvest was $258.1/{\mu}L$ at Group 3 which was much higher comparing to Group 1 ($10.5/{\mu}L$) and Group 2 ($39.9/{\mu}L$) (p<0.001). TNC counts of collected peripheral blood stem cell was $15.36{\times}10^6/kg$ at Group 3 and it's much higher than Group 2 ($13.16{\times}10^6/kg$) and Group 1 ($12.36{\times}10^6/kg$) (p=0.083). There was no significant difference in MNC counts inbetween 3 groups. Conclusions: Circular peripheral blood CD34+ cell counts prior to harvest was much higher at Group 3 than Group 1 and Group 2. Therefore, the number of CD34+ cells on the day of harvest can be used as an accurate predictor for peripheral blood stem cell.

  • Hematopoietic stem cell tranntation is being widely used in an attempt to treat many hematological diseases such as leukemia, anemia, and lymphoma. To evaluate the success of hematopoietic stem cell transplantation, it is very important to determine how rapidly engraftment occurs. Therefore, this retrospective study was conducted to determine which factors affected the term of engraftment during hematopoietic stem cell transplantation, while focusing on the oral intake status. To accomplish this, 416 patients who underwent transplant operations at St. Mary's hospital from May 2006 to April 2008 were evaluated. The long-term engraftment group was characterized as having longer fasting days and more frequent vomiting, diarrhea, and oral mucositis incidences than the short-term engraftment group. In addition, the inhibitors of oral intake such as vomiting, diarrhea, and oral mucositis developed frequently between the pre-transplantation and 2 weeks after transplantation. A significantly negative correlation was observed between the oral intake volume and the duration of the oral intake inhibitors. A multiple regression analysis revealed that the frequency of vomiting and oral mucositis during hematopoietic stem cell transplantation, the length of hospitalization, and the hematocrit level in the 2 weeks after hematopoietic stem cell transplantation were significant predictors of engraftment. The results of this study could be used to establish a guideline for nutritional assessment, nutritional goals, and nutritional support for patients during hematopoietic stem cell transplantation.

  • The polysialic acid (polySia) glycotope covalently modifies cell surface glycoconjugates on cells as evolutionarily diverse as microbes and human. The recent chemical identification of polysialylated glycoproteins in the jelly coat and on the cell surface of the sea urchin egg raises important questions about their biosynthesis and possible function. Using CMP-[$^{14}$ C]Neu5Ac as substrate and cell free preparations from eggs and embryos of the sea urchin Stronglylcentrotus nudus, we have identified a membrane associated CMP-Neu5Ac:poly-$\alpha$2, 8 sialosyl sialyltransferase (polyST) that transfers Neu5Ac to an endogenous acceptor. Optimal conditions for the polyST activity were found to be 2$0^{\circ}C$ in 20 mM MOPS buffer (pH 7.0). The polyST activity was increased 2.7 times by the addition of 10 mM $Mg^2$$^{+}$. The membrane-associated polyST also catalyzed the polysialylation of mammalian ganglioside GD3. Given that no structurally similar natural polysialylated gangliosides have been described, nor were observed in the present study, we conclude that a single polyST activity catalyzes sialylation of the endogenous acceptor and the gangliosides. Using an excess of GD3 as an exogenous acceptor, it was established that the expression of the polyST in S. nudus embryos increased rapidly at the mesenchyme blastula stage and reached at maximum at the gastrula stage. The finding that this polyST in the sea urchin embryo is developmentally regulated raises the possibility that it may play a role in the changing cell and tissue interactions that occur during gastrulation and the early stages of spicule formation.n.

  • Small cell carcinoma mainly occurs in the lung. Approximately 2.5-5% of small cell carcinomas are primary extrapulmonary which are commonly found in the esophagus, GI tract, skin, uterus, and urinary tract. Small cell carcinoma of the head and neck is extremely rare and its prognosis is poor. We report a case of supraglottic small cell carcinoma with cervical lymph node and rib metastasis in a 75-year-old man. The patient was treated with sequential combination of chemotherapy and radiotherapy, but the cancer has progressed. We concluded that we have to find an effective therapy for laryngeal small cell carcinoma.

  • Objectives : The author aimed to evaluate the effect of BuOH fraction(ST) from Schizonepeta tenuifolia on osteoblast proliferation in murine calvarial cells. Methods : The osteoblast separated from murine calvariae was cultivated for 10 days and evaluated the cell function. After the addition of ST on the culture medium, we determined the effect of ST on the cell proliferation, protein synthesis, alkaline phosphatase activity, collagen synthesis, and apoptosis of the osteoblast. Results : 1. ST increased the proliferation of osteoblast, and restored the decreased cell number in glucocorticoid (GC)-treated osteoblast. 2. ST increased protein synthesis of osteoblast, and restored the decreased protein synthesis in GC-treated osteoblast. 3. ST increased ALP activity of osteoblast, and restored the decreased enzyme activity in GC-treated osteoblast. 4. ST increased collagen synthesis of osteoblast, and restored the decreased collagen synthesis in GC-treated osteoblast. 5. ST did not change the survival rate of osteoblast, but increased the survival rate in GC-treated osteoblast. Conclusions : It is concluded that ST might reduce the osteoporosis resulted from augumentation of osteoblast proliferation.

  • Objective: To report the clinical and radiological characteristics of patients with underlying B-cell lymphoma and coronavirus disease 2019 (COVID-19) showing migratory airspace opacities on serial chest computed tomography (CT) with persistent COVID-19 symptoms. Materials and Methods: From January 2020 to June 2022, of the 56 patients with underlying hematologic malignancy who had undergone chest CT more than once at our hospital after acquiring COVID-19, seven adult patients (5 female; age range, 37-71 years; median age, 45 years) who showed migratory airspace opacities on chest CT were selected for the analysis of clinical and CT features. Results: All patients had been diagnosed with B-cell lymphoma (three diffuse large B-cell lymphoma and four follicular lymphoma) and had received B-cell depleting chemotherapy, including rituximab, within three months prior to COVID-19 diagnosis. The patients underwent a median of 3 CT scans during the follow-up period (median 124 days). All patients showed multifocal patchy peripheral ground glass opacities (GGOs) with basal predominance in the baseline CTs. In all patients, follow-up CTs demonstrated clearing of previous airspace opacities with the development of new peripheral and peribronchial GGO and consolidation in different locations. Throughout the follow-up period, all patients demonstrated prolonged COVID-19 symptoms accompanied by positive polymerase chain reaction results from nasopharyngeal swabs, with cycle threshold values of less than 25. Conclusion: COVID-19 patients with B-cell lymphoma who had received B-cell depleting therapy and are experiencing prolonged SARS-CoV-2 infection and persistent symptoms may demonstrate migratory airspace opacities on serial CT, which could be interpreted as ongoing COVID-19 pneumonia.
