PURPOSE: The purpose of the study is to find whether there is any effect on shortening the length of stay of long term patients due to issuing of hospitalization sheets by emergency department. METHODS: For the investigation, 27,948 patients who resided in hospitals over 6 hours from 2006 to 2007 were chosen as the subjects. The main materials for the investigation were various time variables according to the medical records. For the verification of each factor, Student's t-test and Pearson' correlation coefficient were used. RESULTS: There was statistically significant difference in regard to length of stay (p<0.01). The departments related to internal medicine showed that they required longer times in every aspect compared to those of non-internal medicine. There were statistically significant differences (p<0.01) in regard to the time of patients' length of stay and the time of issuing sheets for hospitalization according to the numbers of related department. However, there was no meaningful difference in regard to the waiting time for hospitalization. CONCLUSION: In conclusion, in the cases of long term patients who stayed over 6 hours in 2007 when the random sheets for hospitalization were issued by emergency department, the length of stay was significantly reduced. It was found that the time was more increased in the departments of internal medicine than the departments of noninternal medicine and when the related sub departments increased.

PURPOSE: Procalcitonin (PCT) is a good marker of infection but is still not routinely used. Here, we assessed the usefulness of a semi-quantitative procalcitonin test kit (PCT-Q(R)), a rapid and simple test for evaluating sepsis in the emergency department. METHODS: We recruited 80 patients who visited the emergency center and with systemic inflammatory response syndrome (SIRS). Patients were classified into 4 groups according to PCT levels using PCT-Q[Ed-Trademark signs only have to be given one time in a document]. Mortality rate, bacteremia, severity score, and severity of sepsis (SIRS/sepsis/severe sepsis/septic shock) were assessed with the criteria of the American College of Chest Physicians/Society of Critical Care Medicine Consensus Conference. We calculated a receiver operating characteristic curve (ROC curve), cut-off value, and the related diagnostic parameters of each cut-off value. RESULTS: Higher PCT levels were significantly associated with increased mortality, bacteremia, and severity scores. PCT levels could discriminate between sepsis and severe sepsis at a threshold of 2 ng/ml. CONCLUSION: PCT-Q is a prognostic marker of infectious disease, but low levels do not always indicate a good prognosis. PCT levels increase with aggravation of sepsis, especially at values greater than 2 ng/ml for severe sepsis.

Mesenchymal stem cells (MSCs) have ability to differentiate into multi-lineage cells, which confer a great promise for regenerative medicine to the cells. The aim of this study was to establish a method for isolation and characterization of adipose tissue-derived MSC (pAD-MSC) and bone marrow-derived MSC (pBM-MSC) in pigs. Isolated cells from all tissues were positive for CD29, CD44, CD90 and CD105, but negative for hematopoietic stem cell associated markers, CD45. In addition, the cells expressed the transcription factors, such as Oct4, Sox2, and Nanog by RT-PCR. pAD-MSC and pBM-MSC at early passage successfully differentiated into chondrocytes, osteocytes and adipocytes. Collectively, pig AD-MSC and BM-MSC with multipotency were optimized in our study.
