본 실험은 생체의 특성을 잘 유지할 수 있는 별큰포식세포의 배양법을 확립하고, 배양된 별큰포식세포를 이용하여 간 의 허혈-재관류 과정에서 발생되는 별큰포식세포의 활성화를 재현할 수 있는 시험관내 실험모델을 제작하여 다음의 결과 를 얻었다. 별큰포식세포의 분리에서 collagenase의 관류, stainless 그물의 통과, Percoll gradient centrifugation 및 세포가 배양용기에 부착하는 시간의 차이를 이용한 분별부착법 등의 일련의 조작으로 90% 이상의 순수한 별큰포식세포를 얻을 수 있었다. 흰쥐 1개의 간에서 1~5×107개의 별큰포식세포를 얻었고, 다른 세포의 과다증식없이 별큰포식세포 배양을 10일 정도 유 지할 수 있었다. 배양된 별큰포식세포의 탐식능력은 배양액에 첨가된 latex beads의 탐식정도로 측정하였는데, 그 수가 한 개에서 수십 개로 다양하였다. 크고 둥근 모양의 별큰포식세포가 많은 latex beads를 탐식하였고 작거나 불규칙한 모양의 세포는 탐식 능력이 떨어져, 생체에서의 별큰포식세포의 다양성에 따른 탐식능력의 차이가 시험관에서도 유지되었다. 배양된 별큰포식세포의 무산소-산소재공급 처리한 실험군에서는 70.2%의 세포가 latex beads를 탐식하였고 latex beads 를 탐식한 세포들 중 57.5%의 세포가 5개 이상의 latex beads를 탐식하여 대조군의 48.9%와 44.3%에 비교하여 유의한 증 가를 보여 (p⁄0.01), 허혈-재관류 후에 발생되는 별큰포식세포의 활성화를 직접적으로 설명할 수 있는 결과였다. 결론적으로 본 실험에서 배양된 별큰포식세포는 탐식기능에서 생체의 특성을 잘 유지하였고, 이를 이용한 무산소-산소 재공급 시험관모델은 간의 허혈-재관류 손상에서 별큰포식세포의 역할을 이해하는데 적합한 것으로 생각된다. The aims of this study were to describe a reproducible method for the isolation, purification and primary culture of rat Kupffer cells, and were to develop in vitro system which could provide a tool for the study of ischemia-reperfusion injury. Kupffer cells were isolated following sequential collagenase digestion of the liver by perfusion and enrichment of a nonparenchymal cell fraction by a double-densities gradient centrifugation step using Percoll and were selected by allowing them to adhere to culture vessel for 2 h at 37�C under 5% CO2. The purity of obtained Kupffer cell was about 90% assessed by the phagocytosis of 3 μm latex beads. This method for Kupffer cell isolation resulted in yields of 1~5 ×107 Kupffer cells per liver and Kupffer cells were preserved in maintenance cultures for 10 days. The phagocytic capacity of cultured Kupffer cells was measured according to the amount of latex beads incorporated into the cytoplasm. Larger round Kupffer cells in the culture had higher phagocytic capacity compared with smaller round or irregular shaped Kupffer cells. The different phagocytic capacity of Kupffer cells which was dependent on size and shape in vivo was well preserved during culture. The experimental group of Kupffer cells in culture were sequentially treated with ischemia and reperfusion at 1h and 30 min. The ratio of Kupffer cells having latex beads in their cytoplasm was significantly increased compared with control (p⁄0.01). This result was able to explain the Kupffer cells’ activation after ischemia-reperfusion injury in vivo. In conclusion, Kupffer cells in this culture well resembled the cells in vivo and this in vitro model could provide a valuable tool for the study of Kupffer cells with a key role in pathophysiology of ischemia-reperfusion injury.

Purpose: The purpose of this study was to examine the effect of position change on discomfort and bleeding in patients undergone coronary angiography with a vascular device and required bed-rest. Method: This study utilized nonequivalent control group non-synchronized design. Data were collected from 118 inpatients after coronary angiography and stayed in general ward at Y hospital in Seoul, from June 5 to August 12, 2008. After coronary angiography, position change was performed to the experimental group who consisted of 59 patients. They stayed in supine position just after angiography and then head-up position with 15 degrees was applied 1 hour later. After that, they could change the position alternatively into lateral position with leg down and supine position. The control group was positioned keeping the affected leg immobile with supine position for 4 hours. Results: The experimental group reported significantly more comfortable than control group after position change. There were no significant differences in the grades of bleeding or hematoma at puncture site between the two groups. Conclusion: The position change in patients undergone angiography could be applied without any harm such as bleeding or hematoma, but effective in reducing back pain and subjective patients' discomforts.

Background : Systemic inflammatory reaction syndrome (SIRS) describes the systemic inflammatory process and can be seen following a wide variety of insults. This is the leading cause of morbidity and mortality for patients admitted to the ICU. The arterial keton body ratio (AKBR), serum lactate level and the thyroid hormones, thyroid stimulation hormone (TSH), thyroxine (T4), free thyroxine (FT4) and triiodothyronine (T3) deteriorate in critically ill patients with a poor prognosis. The APACHE (Acute Physiology, and Chronic Health Evaluation) III and multiple organ failure (MOF) score have been known as good prognostic predictors in the ICU. The object of this study was to compare the AKBR, lactate and thyroid hormone levels, and the APACHE III and MOF score between the survivors (SV) and nonsurvivors (NSV) and the correlation among the above predictors. Methods : 35 patients with no known thyroid or liver disease who were admitted to the SICU with the criteria of SIRS were selected. Arterial blood was drawn for the AKBR, and the lactate and thyroid hormones studies. The APACHE III and MOF scorings were done in the first 24 hours of SICU admission. Results : There were no significant difference between SV and NSV except APACHE III (SV: 68.7 24.6, NSV; 92.9 27.6). There were significant correlations between the APACHE III and MOF score (R = 0.688, P< 0.01), APACHE III and lactate (R = 0.575, P< 0.01), and MOF score and lactate (R =0.483, P< 0.01). Thyroid hormones had positive correlations among themselves only. Conclusions : We conclude that APACHE III is the only good predictor of mortality. The APACHE III, MOF score, and lactate level show good correlations indicating the severity in condition of the ICU patients. (Korean J Anesthesiol 1999; 37: 799∼806)
