일반적인 버섯 배지(미강 10%), 폐 한방슬러지를 10% 첨가한 배지, 그리고 미강 10%와 폐 한방슬러지 10%를 혼합한 배지에서 재배한 팽이버섯의 면역기능 강화효과를 알아보기 위해 물 추출물과 에탄올 추출물로 분리하여 실험하였다. 그 중 폐 한방슬러지 10%를 첨가한 배지에서 재배한 팽이버섯의 에탄올 추출물을 첨가하였을 때, 비장세포의 증식을 크게 유도하였으며 또한 IL-6, TNF-${\alpha}$, IFN-${\gamma}$ 분비를 유도하였다. 그리고 B세포의 증식반응과 면역글로불린 생산도 증가하였으며, 대식세포주의 일산화질소 분비와 IL-6, TNF-${\alpha}$, GM-CSF 생산도 증가하였다. 또한 복수암 유발 종양세포를 이용한 항종양 효과를 측정 한 결과 대조군의 평균 21.1일보다 실험군은 24.5일로 16.1%의 수명 연장효과가 나타났다. 따라서 폐 한방슬러지를 이용하면 수입에 의존하고 있는 버섯 재배 배지 원료를 절약할 수 있으며 면역세포조절 기능을 강화시키는 기능성 버섯을 얻을 수 있다고 생각한다.

Objectives : The purpose of this study is to investigate Acute and Subacute Toxicity, and Anti-cancer Effect of H Herbal-acupuncture on mice and rats. Methods : Balb/c mice were injected intraperitoneally with H Herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were experimented in the same way for subacute toxicity test. H Herbal-acupuncture was injected into abdomen of mice having S-180 cancer cell line. Result : 1. During the test, $LD_{50}$ could not be counted since there was no expired subjects. 2. In an acute toxicity test, the loss of motility and reflex action was observed, but weight increased in the treatment group, compared with those in the normal group (P<0.05). 3. In an acute toxicity test of serum biochemical values of mice, glucose increased in the treatment group II while total cholesterol was increased in the all treatment groups (P<0.05). 4. In a subacute toxicity test, a little loss of motility and reflex action was observed in the treatment group. Weight of mice in the treatment group decreased on the 28th day. 5. In a subacute toxicity test, liver weight was decreased but lung weight of mice increased in the all treatment groups (P<0.05). 6. As a result of measuring Complete Blood Count test (CBC) of rat, HCT was decreased in treatments even though it was not significant, compared with the normal group (P<0.05). 7. In a serum biochemical value test of subacute toxicity, total protein and albumin decreased in the all treatment groups. Creatinine, glucose, GOT increased in the treatment group I compared with the control group. Alkaline phos-phatase decreased in treatment II group, compared with the control group (P<0.05). 8. Median survival time that was measured in the rats treated with sarcoma-180 cancer cell Median decreased in the treatment group, compared with the control group (P<0.05). 9. Natural killer cell activity showed significant reduction at 100:1 and 10:1 E/T ratio while it increased at 50:1 E/T ratio. It is inferred that there was an error in the experiment (P<0.05). 10. In an interleukin-2 productivity test, even though it decreased in lung cancer, and increased in abdomen cancer, but it was only a small difference (P<0.005). 11. After injecting B16F10 cell into a capillary vessel of C57BL/6 mice and generating metastasized lung cancer, the lung was examined with the naked eye. It was not possible to see metastasized cancer in the all groups on the seventh day but the cancer was viewed on the fourteenth day. The number and volume of metastasized cancer in the treatment group enlarged in the treatment group, compared with the control group. Conclusion : According to the results, H herbal-acupuncture took no effects in cancer.

Purpose: Extensive lumbosacral defects after removal of spinal tumors have a high risk of wound healing problems. Therefore it is an effective reconstructive strategy to provide preemptive soft tissue coverage at the time of initial spinal surgery, especially when there is an instrument exposure. For soft tissue reconstruction of a lumbosacral defect, a variation of the gluteal flap is the first-line choice. However, the musculocutaneous flap or muscle flap that is conventionally used, has many disadvantages. It damages gluteus muscle and causes functional disturbance in ambulation, has a short pedicle which limits areas of coverage, and can damage perforators, limiting further surgery that is usually necessary in spinal tumor patients. In this article, we present the superior gluteal artery perforator turn-over flap that reconstructs complex lumbosacral defects successfully, especially one that has instrument exposure, without damaging the ambulatory function of the patient. Methods: A 67 year old man presented with sacral sarcoma. Sacralectomy with L5 corpectomy was performed and resulted in a $15{\times}8\;cm$ sized complex soft tissue defect in the lumbosacral area. There was no defect in the skin. Sacral stabilization with alloplastic fibular bone graft and reconstruction plate was done and the instruments were exposed through the wound. A $18{\times}8\;cm$ sized superior gluteal artery perforator flap was designed based on the superior gluteal artery perforator and deepithelized. It was turned over 180 degrees into the lumbosacral dead space. Soft tissue from both sides of the wound was approximated over the flap and this provided in double padding over the instrument. Results: No complications such as hematoma, flap necrosis, or infection occurred. Until three months after the resection, functional disturbances in walking were not observed. The postoperative magnetic resonance imaging scan shows the flap volume was well maintained over the instrument. Conclusion: This superior gluteal artery perforator turn-over flap, a modification of the conventional superior gluteal artery perforator flap, is a simple method that enabled the successful reconstruction of a lumbosacral defect with instrument exposure without affecting ambulatory function.

담자균류인 영지 Ganoderma lucidum의 자실체를 열수추출한 후 얻은 단백 다당체를 DEAE cellulose 이온교환수지와 Sepharose CL-4B 젤 여과법을 이용하여 분리 정제하였다. 정제한 분획들을 각각 CR, IN, IA, GL과 GH로 명명하였다. 각각의 성분을 20mg/kg/day 용량으로 투여하였을 때 sarcoma 180 고형암에 대하여 Fr. GL이 81%의 가장 높은 종양 억제을을 나타냈으며 그 분자량은 47,000 dalton이었다. 그 구성성분은 82% 다당류, 8% 단백질 및 0.9% hexosamine 이었다. 그 다당류를 구성하는 단당류를 분석한 결과 glucose, galactose, mannose, fucose순으로 함유되어 있었다. 항암작용의 기전을 밝히기 위하여 마우스의 면역에 미치는 항암 성분의 영향을 연구한 결과 활성화된 마크로파지에서 분비되는 superoxide anion 양을 1.6배로, 그리고 hemolytic plaque assay에서의 용혈반 형성 세포수를 6배로 각각 증가시켰다. 이 결과로 항암작용은 고형암에 직접적으로 세포독성을 나타내는 것이 아니라, 면역세포를 활성화 혹은 강화시키는 작용임을 알 수 있다.

From January 1994 to August 1995 we performed 270 cases of fine needle aspiration cytology for bone and soft tissue lesions. Among them 137 cases were diagnosed histologically. Sixty-seven cases were benign and 70 cases were malignant. We analysed these on the aspect of sensitivity, specifity, positive predictive value, negative predictive value of the cytologic examination. Malignant cases consisted of bone tumor 29 cases; soft tissue tumor 25 cases; and metastatic tumor 16 cases. The sensitivity and specifity of the aspiration cytology for malignant tumor were 67.8% and 97%, respectively. The positive and negative predictive value of aspiration cytology were 97.4% and 72.7%, respectively. Among them 40 cases were primary bony lesions; 14 benign lesions, 26 malignamt bone tumors. Sensitivity of aspiration cytology for these primary bony lesion was 90%(18/20) and its specifity was 100%(13/13). Three cases showed atypical cells in cytology but with biopsy we could find them as one benign and two malignancies. Two cases of manignancy showed negative result in cytology; one was parosteal sarcoma of proximal femur and the other was osteosarcoma of proximal tibia which was biopsied already at other hospital. Although the overall sensitivity and specifity for malignant bone and soft tissue tumors were relatively low and not so predictable, the fine needle aspiration cytology for primary bony lesion was useful in the differential diagnosis of benign or malignancy.

이식후 발생하는 림프증식성 질환(PTLD)은 양성 다크론성 B림프구 증식증으로부터 악성의 단크론 림프종에 이르기까끼 다양한 임상상을 보이는 질환이다. PTLD는 Epstein-Barr virus(EBV)와 과도한 면역억제와 밀접한 관계가 있다. 국내에서는 1997년 성인에서 신 이식 후 발생한 예가 처음 보고되었으며, 소아에서는 간 이식 후 발생한 예가 있을 뿐 신 이식 후 발생한 증례의 보고는 없어 이 보고가 국내 최초로 신이식 소아에서 발생한 PTLD 증례이다. 환자는 9세 남아로서 긴이식후 4개월후에 PTLD가 발생하였으며 주된 임상 양상은 발열, 림프절 종대와 혈변이었다. 림프절과 대장의 생검조직 에서 EBV in situ hybridization이 양성이고, 조직학적으로 B 세포계열의 PTLD에 합당한 소견이었다. 모든 증상은 면역억제제 감소와 ganciclovir 치료로 완전 관해되었다.

To study the differentiating cytomorphological features of Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) using fine needle aspiration cytology (FNAC), cytomorphological features of 16 patients with HL (n=8) or ALCL (n=8) were analyzed. In the initial cytological diagnosis prior to biopsy, HLs were properly diagnosed in 4 out of 8 cases (4 HL, 2 atypical, 2 benign), whereas all ALCL were diagnosed as malignancies. However, correct diagnosis of non-Hodgkin lymphoma (NHL) was made in only two ALCL patients (2 NHL, 1 HL, 1 sarcoma, 4 malignancy without specific type). Overall, the percentage of large abnormal cells ranged from 30% to 90% in ALCL except for one case, whereas it was less than 5% in all 8 HL. A spectrum of atypical cells was more characteristic of ALCL. In contrast, HL showed an sharp difference between reactive lymphoid cells and neoplastic ones (bimorphic pattern). Moreover, the emergence of kidney-shaped abnormal cells or wreath-like multinucleated cells was helpful in diagnosing ALCL. The combination of thesefeatures would be useful in differentiating HL and ALCL. Nevertheless, these two types of lymphomas cannot be definitely distinguished based on cytomorphological features alone. Therefore, the aim of FNAC would be to suggest a specific diagnosis and indicate the need for a biopsy.

Purpose : It is very important to endow the cancer patients underwent chemotherapy with satisfactory quality of life (QOL). However, little is known about the factors influencing QOL during chemotherapy. Therefore, we designed this study to find out the factors influencing QOL in the cancer patients who underwent chemotherapy. Methods : Ninety-seven cancer patients were studied, prospectively. The patients' characteristics were as follows; median age(range): 48(19{\sim}83) years, male:female; 57:40, PS:0,1/2,3;55/42 patients, diagnosis(number): lymphoma (28), lung cancer (22), gastrointestinal cancer (18), sarcoma (12), breast cancer (12), gynecological cancer (5), Stage: I,II/III.IV;37/60 patients. We used EORTC QLQ-C30 questionnaires to evaluate QOL. EORTC QLQ-C30 scores were performed before the onset of chemotherapy and after the end of 3 cycles of chemotherapy. The correlation of these scores with performance status (PS), diagnosis, disease stage, response to chemotherapy, and regimen related toxicity was evaluated. Results : The responder group (CR, PR) demonstrated marked improvement of social functional and emotional scales to non-responder group (SD,PD) (P=0.024, 0.045). Non-hematologic regimen related toxicity such as mucositis, nausea and vomiting was significantly correlated with pain scale change (P=0.043). Other factors had no notable correlation with QOL changes. Conclusion : Our preliminary study results may suggest as follows. The response to chemotherapy is associated with the change of social functional and emotional scales and the severity of non-hematologic regimen related toxicity is associated with pain scale change.
