성희경,서병배,김용호 한국미생물학회 2002 미생물학회지 Vol.38 No.3

주정중독환자에서 초기 비특이적 면역력의 주된 반응인 백혈구 탐식작용을 이용하여 이들 환자들의 건강관리를 용이하게 할 수 있는지를 알아 보기위하여 백혈구 탐식 작용력을 측정하고자 실시하였고, 연구대상은 주정중독 의존형으로 진단된 남자 95명, 여자 3명과 대조군으로서는 건강한 헌혈자 32명을 대상으로 실시하였다. 또한 주정중독환자의 건강상태를 확인하기 위하여 백혈구수, 혈색소, 적혈구 평균용적, 혈청 단백질 전기영동, 림프구 아형 분리 및 림파구 유약화 시험도 실시하였따. 분석결과에서 혈색소와 적혈구 평균용적은 대조군에 비하여 신, 장기 입원 환자군에서 유의할만한 차이를 보였으며(P<0.05), 총 T와 B 림프구는 감소하였고, $T_{Helper}/T_{suppressor}$ 비율은 $1.6{\pm}0.8%$로 증가하였다. 특히 신, 장기입원 주정중독자의 Staphylococcus aureus Cowan I을 사용한 백혈구의 phagocytic plaque 형성력에서도 대조군에 비하여 현저하게 저하되었고, 이제까지 보고된 바 없는 특이한 strange body, 사슬상 탐식현상을 관찰 할 수 있었다. 따라서 Staphylococcus aureus Cowan I을 사용한 백혈구의 phagocytic plaque 형성 시험은 특별한 기구가 없이 간단하게 이용 가능하여 주정중독환자의 초기 면역력 측정에 매우 유용한 방법임을 알 수 있었다. This study was conducted to develop a method for direct determination of phagocytic activities in human circulatic systems and to measure the phagocytic activities in human leukocytes from the alcoholics, since phagocytic activity was considered to be very important in human immune mechanism at early stage for the health care of the alcoholics. The subjects for this study were 130 among which 95 males and 3 females were diagnosed as alcoholism and 32 was healthy blood donors. A thin layer of heat-killed Staphylococcus aureus Cowan I was placed on a plastic dish and reacted with whole blood to measure the phagocytic plaque formation by human leukocytes. In order to determine the health conditions of the subjects, some clinical laboratory tests, such as white blood cell counts, hemoglobin contents (Hgb), mean corpuscular volume of red blood cells(MCV), serum electrophoresis, B and T-lymphocytes, T-lymphocyte subtypes and phytohemagglutination test were also implemented. Compared to the non-alcoholism, new and old alcoholic inpatients showed statistically significant differences on levels of Hgb and MCV (p<0.05), but showed that T and B-lymphocyte numbers decreased and Helper T cell/Suppressor T cell ratio ($1.6{\pm}0.8$%) increased. Compared to non-alcoholism, phagocytic plaque activities of leukocytes from alcoholic patients decreased significantly and an unusual pattern in phagocytic plaque was observed, showing a strange body and chain shaped phagocytosis. Based upon these results, it is concluded that a phagocytic-plaques of Staphylococcus aureus Cowan I by leukocytes was very simple and useful method for the early immunological determination of phagocytic activities in alcoholic patients without requiring any special equipments.

알코올 중독자의 폐렴관리와 같은 건강관리에 필요한 비특이 면역력, 면역기능을 측정하기 위하여 알코올 중독 의존형으로 입원한 신, 구환자군에 대하여 다음과 같은 결과를 얻었다. 대조군에 대한 알코올 중독증은 MCV, 혈당, ΥGTP를 이용한 생물학적 측정 결과에 의하여 확인 하였으며, 기타 측정 항목은 대조군과 유사한 결과를 나타내었다. 림프구 아형 분석 결과 대조군은 한국인 참고치와 매우 유사하였으며, 실험군 CD4+를 제외한 CD3+, CD8+, CD19+이 감소되었고, CD4+/CD8+ 비율은 통계적으로 유의하게 증가되어 있음을 알 수 있었다. 따라서 실험군의 면역기능과 림프구 증식능은 대조군에 비하여 현저하게 저하되었으며, 탐식세포 탐식능 및 유주능도 대조군에 비하여 현저하게 감소되었다. 탐식세포의 유주능과 CD4+의 증가, CD4+/CD8+ 비율의 증가와 PHA에 의한 림프구 증식능의 감소 및 CD3+, CD19+ 감소등은 상호관련성을 가지고 일치된 결과를 보여 대조군에 비하여 현저하게 저하된 탐식세포의 탐식기능과 함께 알코올 중독자의 비특이 면역계, 면역기능이 현저하게 저하되어 있음을 알 수 있었다. 그러나 알코올 중독 의존형으로 입원한 신, 구환자간의 비교분석 결과 총단밸질, 혈색소, 림프구 증식능, 탐식세포 탐식능, 유주능에서 신환자군에 비하여 구환자군이 대조군에 다소 근접되어가는 결과로부터 치료에 따라 숙주의 세포성, 체액성 면역기능이 회복되어가고 있음을 알 수 있었다. 또한 결과 알코올중독자의 비특이적 면역능의 측정을 위한 탐식세포 탐식능, 유주능은 숙주, 미생물측의 활성화 자극인자가 모두 포함된 phagocytic plaque film법에 의하여 측정함이 의의 있는 평가를 할 수 있을 것으로 보며, CD4+/CD8+ 림프구 아형 비율을 이용한 면역기능의 측정은 알코올 중독자의 건강 관리를 위한 면역력 측정에 유용한 방법이라고 생각된다. Alcoholics increased susceptibility to microbial infection that is associated with decreased immunity. but there has been little experimental evidence to support alcoholics-induced increase of microbial infection directly in non-specific immunity. Therefore, we were used the method of phagocytic-plaque including all the stimulating factors for the phagocytosis, subtypes of lymphocytes and T-lymphocyte proliferation. The experimental groups were divided into 3 groups: (1) alcoholics who were hospitalized less than 1 week (newly hospitalized alcoholics), (2) alcoholics who were hospitalized more than 2 weeks (old hospitalized alcoholics), (3) healthy blood donors. We have studied 98 alcoholics and 35 healthy blood donors and control groups. A physician has checked the biological markers and diagnosed the body-condition alcoholics. The immunity and non-specific immunity on the alcoholics were analyzed by using the simultest kit and flow cytometry. Proliferation of the lymphocytes was analyzed by the phytohemmagglutinine mitogen. Phagocytosis and migration properties of leukocytes were identified on the layer formed by Staphylococcus aureus Cowan I strain. Biological markers of alcoholics and control groups, by such as blood glucose, Υ-glutamyl transpeptidase and mean corpuscular volumes of red blood cells, were determined by biochemical and hematological methods. Compared with control groups, cluster of differentiation (CD)3+, CD8+ and CD19+ in alcoholic were more decreased except CD4+/CD8+ ratio. Proliferation of the T-lymphocytes, phagocytosis and migration properties of the leukocytes in alcoholics were decreased compared with those of control groups. According to the results observed in our experiment, they can be summerized as follows: 1. Cellular, humoral and non-specific immunities, are markedly decreased in alcoholics than those in control groups. 2. It is inferred that Phagocytic plaque formation is a very useful method to evaluate phagocytosis and migration properties of the alcoholic leukocytes 3. It is thought that the subtypes of lymphocytes, especially CD4+/CD8+ ratio, are essential methods to analyzed the alcoholic immunity. 4. Specific and non-specific immunity on the old hospitalized alcoholics was slightly increased, which depends upon the alcoholic medication.
