목 적 : 조산아에서 출생 직후 말초 혈액의 C-반응성 단백(C-reactive protein, CRP) 농도가 자궁 내 염증의 침범 부위 또는 진행 정도에 따라 어떻게 달라지는 지 알아봄으로써 출생 직후 말초 혈액 CRP 측정의 임상적 의의와 유용성에 대해 연구하고자 하였다. 방 법 : 2005년 9월부터 2009년 4월까지 동국대학교 일산병원에서 출생하여 신생아 중환자실에 입원한 재태기간 32주 미만의 조산아 187명을 연구 대상으로 했다. 연구 대상을 'no histologic chorioamnionitis' [HCAM (-), 85명]군과 'histologic chorioamnionitis' [HCAM (+), 102명]군으로, 다시 HCAM (+)군을 'funisitis' [F (+), 49명]군과 'no funisitis' [F (-), 53명]군 및 'funisitis/amnonitis' [FA (+), 58명]군과 'isolated chorio-deciduitis' [FA (-), 44명]군으로 분류하였다. 출생 직후 말초 혈액의 high sensitivity CRP 농도를 측정하여 각 군 간에 비교하였다. 결 과 : HCAM (+)군, F (+)군, F (-)군, FA (+)군의 말초 혈액 CRP 농도는 모두 HCAM (-)군에 비해 높았으나(평균=0.29 vs. 0.06 mg/dL; 0.52 vs. 0.06; 0.07 vs. 0.06 mg/dL; 0.46 vs. 0.06 mg/dL, P<0.05), FA (-)군의 경우는 HCAM (-)군과 유의한 차이가 없었다. 또한, F (+)군과 FA (+)군의 말초 혈액 CRP 농도는 각각 F (-)군 및 FA (-)군보다 높았다 (평균=0.52 vs. 0.07 mg/dL; 0.46 vs. 0.05 mg/dL, P<0.05). HCAM (-)군과 F (+)군, HCAM (-)군과 FA (+)군을 감별하기 위한 경우, 말초 혈액 CRP 농도의 cut-off 값을 0.02 mg/dL으로 정하였을 때 민감도와 특이도는 모두 94% 및 53%였다(P<0.0001). 또한, F (+)군과 F (-)군, FA (+)군과 FA (-)군을 감별하기 위한 경우, 말초 혈액 CRP 농도의 cut-off 값을 0.02 mg/dL으로 정하였을 때 민감도는 각각 79%와 86%, 특이도는 모두 53%였다(P<0.002, P =0.000). 말초 혈액 CRP 농도가 0.02 mg/dL 이상인 경우, 임상적 융모양막염, 확증된 조기 발현 패혈증, 조직학적 융모양막염, 제대 혈관염의 빈도가 높았다. 결 론 : 재태기간 32주 미만의 조산아에서 출생 직후 말초 혈액 CRP 농도는 태반의 염증이 제대 혈관염이나 양막염까지 진행했을 때 유의하게 증가하여 조직학적 융모양막염의 진행 정도를 잘 반영하였고, 제대 혈관염이나 양막염의 감별 진단에 어느 정도 진단적 가치가 있을 것으로 생각된다.

In this study, the micronucleus test with peripheral blood using acridine orange coated slides was evaluated in mice treated with mitomycin C(MMC) at doses of 0.5, 1.0 and 1.5 mg/kg body weight. The peripheral bloods were obtained at 0, 24, 48 and 72h after treatment. The frequencies of micronucleated reficulocytes(MNRET) in the MMC-treated groups increased dose-dependently, and showed a peak time at 48h after treatment. We also performed the sex differences of MNRET frequency in 0.5 mg/kg MMC treated group, and we observed no sex differences in this experiment. And we evaluated the usefulness of a direct acting clastogen, N-methyl-N-nitrosourea and a indirect acting clastogen, benzo(a) pyrene as the positive control in this supravital micronucleus test. They also caused a significant increase in MNRET frequencies. These results suggest that the supravital staining micronucleus test using MNRET can be useful tool to evalulate the quantitative and qualitative assessment of genotoxicity in vivo compared to classical in vivo micronucleus test using bone-marrow cells.

The treatment of chronic digital pain and cold intolerance due to Raynaud's phenomenon is quite difficult especially it is combined with scleroderma. Several surgical trial such as cervicothoracic sympathectomy have been attempted for the medically unresponsible Raynaud's phenomenon, but their results were unsatisfactory. We have tried peripheral periarterial sympathectomy for the 44 years old female patient who had medically unresponsible severe Raynaud's phenomenon with scleroderma. Periarterial adventitial stripping was performed at the level of wrist, superficial palmar arch, common digital artery and proper digital artery about 1.5-2 cm in length. Preoperative angiography and radioactive angiography were done and preoperatively and postoperatively the blood flow was measured by the desk top computer-aided histogram. Both hands digital pain were markedly reduced after operation and blood flow increased as compaired with the preoperative measure.

Background: Complete blood count (CBC) results play an important role in peripheral blood smear (PBS) examinations. Many descriptions in PBS reports may simply be translated from CBC parameters. We developed a computer program that automatically generates a PBS draft report based on CBC parameters and age- and sex-matched reference ranges. Methods: The Java programming language was used to develop a computer program that supports a graphical user interface. Four hematology analyzers from three different laboratories were tested: Sysmex XE-5000 (Sysmex, Kobe, Japan), Sysmex XN-9000 (Sysmex), DxH800 (Beckman Coulter, Brea, CA, USA), and ADVIA 2120i (Siemens Healthcare Diagnostics, Eschborn, Germany). Input data files containing 862 CBC results were generated from hematology analyzers, middlewares, or laboratory information systems. The draft reports were compared with the content of input data files. Results: We developed a computer program that reads CBC results from a data file and automatically writes a draft PBS report. Age- and sex-matched reference ranges can be automatically applied. After examining PBS, users can modify the draft report based on microscopic findings. Recommendations such as suggestions for further evaluations are also provided based on morphological findings, and they can be modified by users. The program was compatible with all four hematology analyzers tested. Conclusions: Our program is expected to reduce the time required to manually incorporate CBC results into PBS reports. Systematic inclusion of CBC results could help improve the reliability and sensitivity of PBS examinations.

The aim of this study is to determine the phagocytosis-promoting factor(s) for feline peripheral blood polymorphonuclear cells (PMN) by culture supernatant from mono-nuclear cells (MNC) treated with egg white derivatives (EWD). The phagocytic activity of PMN was analyzed by a flow cytometry system. The EWD did not show direct effect on the phagocytic response of PMN. The phagocytic activity of PMN was enhanced by culture supernatant from MNC but not PMN treated with EWD. Therefore, it was suggested that the enhanced phagocytic activity of feline PMN could be mediated by humoral factor(s) released from MNC treated with EWD. Thus, the phagocytosis-promoting factor(s) in supernatant fraction from MNC culture treated with EWD were isolated by reverse phase high pressure liquid chromatography. The resulting supernatant fraction on 29.02 minutes of retention time showed high phagocytic activity of PMN. The molecular weight of this supernatant fraction was 16 to 18 kDa when analyzed by capillary electrophoresis. The isoelectric point was pH 5.76 when assessed by ion-exchange chromatography. These results suggest that EWD stimulates feline MNC to elaborate a phagocytosis-promoting factor, 16 to 18 kDa of molecular weight, which could be an important mediator for the enhancement of phagocytic activity of feline peripheral blood phagocytes. Further study will be needed to elucidate this phagocytic factor.

To examine the effects of Polygonum multiflorum on white rats with deteriorated immunity caused by methotrexate, first of all, methotrexate was fed to the rats once a day for 4 days. After the immune response of the rats are dereriorated, dried extracts of Polygonum multiflorum mixed in water was fed to the white rats once a day for 144days. The next conclusion was made by examining the rates of B-cells and T-cells of the peripheral blood and the changes in rates of CD4+ T-cells and CD8+ T-cell of the blood sampled from the spleen and peripheral region . Polygonum multiflorum has an effect of increasing immune responses on white rats with deteriorated immunity caused by MTX. Especially the count of CD4+ T-cells of the peripheral blood and the count of CD4+ T-cell of the spleen proved the significant effect o( increasing immune responses statistically . Verification of the effects of the Polygonum multiflorum should be made through comparitive .studies using various immune response indexes. Also additional studies for a modern and practicible application of Polygonum multiflorum seems to be needed.

Recent studies suggest that immunization with autologous dendritic cells (DCs) results in protective immunity and rejection of established tumors in various human malignancies. The purpose of this study is to determine whether DCs are generated from peripheral blood mononuclear cells (PBMNs) by using cytokines such as F1t-3 ligand (FL), granulocyte macrophage-colony stimulating factor (GM-CSF), IL-4, and TNF-${\alpha}$, and whether cytotoxic T cells activated against the thyroid cancer tissues by the DCs. Peripheral blood was obtained from 2 patients with thyroid cancer. DCs were established from PBMNs by culturing in the presence of FL, GM-CSF, IL-4, and TNF-${\alpha}$ for 14 days. At day 14, the differentiated DCs was analyzed morphologically. The immunophenotypic features of DCs such as CDla, CD83, and CD86 were analyzed by immunofluorelescence microscopy. At day 18, DCs and T cells were incubated with thyroid cancer tissues or normal thyroid tissues for additional 4 days, respectively. DCs generated from the PBMNs showed the typical morphology of DCs. Activated cytotoxic T lymphocytes (CTLs) were observed also. DCs and the CTLs were attached to the cancer tissues on scanning electron microscope. The DCs activated the CTLs, which able to specifically attack the thyroid cancer. This study provides morphologic evidence that the coculture of T cells/cancer tissues activated the T cells and differentiated CTLs. The CTLs tightly adhered to cancer tissues and lysed cancer tissues vigorously. Therefore DCs could be used as potential vaccines in the immunotherapy.

The effects of cortisol on proliferation and apoptosis of tilapia surface immunoglobulin positive ($sIg^+$) lymphocytes isolated from different tissues were investigated. $sIg^+$ lymphocytes from the tilapia head kidney (HK) and spleen showed a higher proliferation and lower intracellular calcium ($Ca^{2+}{_i}$) level to Ig-crosslinking compared with peripheral blood $sIg^+$ lymphocytes. Peripheral blood $sIg^+$ lymphocytes stimulated with lipopolysaccharide (LPS) showed high levels of apoptosis in the presence of cortisol. HK and to a lesser extent spleen $sIg^+$ lymphocytes, although less sensitive than their equivalent in peripheral blood, showed cortisol-induced apoptosis irrespective of LPS stimulation of control levels. Compared to plasma values measured during stress conditions, proliferation regardless of LPS stimulation was apparently suppressed by cortisol that is effective in inducing a significant increase in apoptosis in all three different cell populations of $sIg^+$ cells, suggesting the immunoregulatory effect of cortisol in both LPS stimulated and non-stimulated conditions. Different sensitivity of $sIg^+$ cells to the cortisol, in regard to developmental stage and activity, could be related in inhibiting excessive and continuing depletion of $sIg^+$ lymphocytes.
