$23{\sim}40$세 (평균 연령 31.6세)의 자궁내막증 환자35명 (1기 7명, 2기 7명, 3기 14명, 4기 7명)을 대상으로 gonadotropin-releasing hormone agonist (Goserelin) 3.6 mg을 한달 간격으로 6개월 복부의 피하에 이식한 후 자궁내막증에 대한 치료 효과와 부작용을 알아보기 위하여 매달 호르몬 검사와 증상에 대한 설문조사를 시행하였다. 투여 1개월 후 혈청 estradiol농도는 30 pg/mL이었고 이후 치료중 $10{\sim}20$ pg/mL를 유지하였으며 투여를 중간한 1개월 후 50 pg/mL로 증가하였다. 혈청 LH농도는 치료 중 유의하게 감소하였으며 투여를 중단한 후 증가하였다. FSH는 투여 1개월 후 감소하였으나 2개월후부터 계속 치료전과 같은 농도를 유지하였다. 혈청 CA-125치는 19명중 10명에서 치료전에 35 mIU/mL이상으로 증가되었으며 치료 2개월 후부터 모두 정상으로 감소되었다. 월경곤란증은 치료 3개월째 완전히 소실되었고 성교통은 치료가 끝날 때까지 20%의 환자에서 지속되었다. 백혈구수, 혈색소, 전해질, 단백질, 빌리루빈 및 간효소는 치료 중 모두 정상이었다. 혈압과 체중도 치료전, 치료중에 변화가 없었다. 투여후 86%의 환자가 안면홍조를 63%에서 질건조증을 20%가 두통, 우울을 호소하였다. 이와 같은 부작용은 투여를 중단한 1개월 후 모두 소실되었으며 부작용 때문에 투여를 중단한 예는 없었다. 이상의 결과로 GnRH-a는 난소의 estradiol생산을 완벽하게 중단시키고 골반증상을 완하시켜 자궁 내막증 치료에 효과적이라고 사료되며 안면홍조와 같은 부작용의 빈도가 높기 때문에 향후 호르몬 보충요법을 병행하는 것이 바람직 하다고 사료된다.

Purpose: In the breast cancer patient, lymphatic mapping and sentinel lymph node biopsy are the most important procedure for axillary lymph node staging. We aimed to compare the three radiocolloids [$^{99m}Tc$-antimony trisulfide colloid (ASC), $^{99m}Tc$-tin colloid (TC), and $^{99m}Tc$-human serum albumin (HSA)] for sentinel lymph node mapping. Subjects and Methods: Totally, 397 patients with clinically N0 stage were enrolled. $^{99m}Tc$-ASC was injected in 202 out of 397 patients, $^{99m}Tc$-TC was injected in 120 patients, and $^{99m}Tc$-HSA was injected in the remaining 75 patients. The sentinel lymph nodes were localized by lymphoscintigraphy and selected using intraoperative gamma probe. All sentinel lymph nodes were investigated by intraoperative pathologic consultation. The axillary lymph nodes which were harvested by the lymph node dissection were also investigated. Results: The patients of each group showed similar clinical characteristics. There were no significant differences (p>0.05) in the identification rate of sentinel lymph nodes (IR), false negative rate (FNR), and negative predictive value (NPV). The axillary lymphadenectomy revealed axillary lymph node metastases in those three groups (ASC-33.2%, TC-31.7%, HSA-22.7%). The IR, FNR, and NPV were not significantly different among those groups. Conclusion: Those three $^{99m}Tc$-labeled radiocolloids showed equivalent results in sentinel lymph node mapping of breast cancer.

Purpose: For an isolated tear of the subscapularis tendon, the presented technique using a subclavian portal provides both a good angle for anchor placement and sufficient space for managing the upper portion of a subscapularis tendon tear. Materials and Methods: The conventional method needs 2 additional portals for traction, debriding the footprint and anchor fixation for repair. The presented technique requires only an anterior portal for suture management and a subclavian portal without cannula for suture anchoring and placement of suture hooks. Results: The two suture limbs of the anchor can be placed on the subscapularis tendon by the switching technique and these limbs are repaired sequentially. Conclusion: This technique is simple and reproducible and it can be applied to partial tears and minimally retracted subscapularis tears.

Purpose : We report a result of arthroscopic treatment of the recurrent prepatellar bursitis. Materials and Methods : Between March 2001 and May 2002, we treated 4 patients with prepatellar bursitis, the average follow-up period was 14.5 months. The causes were acute trauma 3 cases and repeated minor trauma 1 case. All cases were recurred after previous history of the conservative therapy at other hospital but one was a recurred case after operative excision. Operative technique was as follows. Before inserting the arthroscope, the bursa was inflated with saline. The portals fur 4 mm diameter arthroscope were placed 1cm away from the bursal sac through small skin incision. Superficial layer of the bursa was resected first and then deep portion was the next. Several percutaneous mattress sutures were applied to the overlying skin with deep tissue, and compressive dressing was applied and maintained for 2 weeks. Results : All 4 cases were no recurrence, no pain, no tenderness. The results were considered satisfactory, Two cases of mild skin dimpling at suture site were observed. Conclusion : Arthroscopic treatment of the prepatellar bursitis is an another method of operation technique fur recurrent prepatellar bursitis, however long term follow-up will be needed about recurrence.

A 6-year-old female Shih-tzu dog was referred with left elbow joint mass associated with weight bearing lameness. Ultrasonography demonstrated an encapsulated hyperechoic mass at the left elbow joint. Radiography was performed on elbow joint, chest, and abdomen, but there was no evidence of metastasis. Clinicopathologic examination revealed the existence of neoplastic cells with anisocytosis, pleomorphism and increased nuclear-cytoplasmic ratio. The left forelimb was amputated for cure. Histopathological examination diagnosed the mass as a malignant peripheral nerve sheath tumor. During the 4 weeks follow-up, the patient showed full remission and adopted to walk with remaining three legs. Thereafter, the tumor recurred after 5 months of first surgery at the operation site and other two cutaneuos regions. Cytology test revealed the mesenchymal originated tumor cells with malignancy. These tumors were surgically removed and histopathological examination of the resected tissue revealed the recurrence of primary tumor and metastasis. Metronomic therapy with cyclophophamide (10 mg/$m^2$, PO, sid) and piroxicam (0.3 mg/kg, PO, sid) had been adopted for 5 months. At 26 months of follow up after the first surgery, the dog alive with satisfactory quality of life. Aggressive surgical resection with metronomic chemotherapy should be the most effective treatment for malignant peripheral nerve sheath tumor.

Background: Interleukin-12 (IL-12) can induce antitumor effects in vivo. This antitumor effect is associated with T cell infiltration but the effect of IL-12 on the steps of T cell migration into the tumor tissue has not been fully elucidated. This study focused on the effect of IL-12 on the tumor growth and the metastasis and on the expression of E-selectin, an adhesion molecule which is activated endothelial specific in its expression. In addition, we studied whether the expression of E-selectin is associated with the TNF-$\alpha$, a cytokine that its production is increased by IL-12 and has functions inducing a variety of adhesion molecules. Methods: Mice of C57BL/6 strain were injected with Lewis lung cancer cells followed by either IL-12, TNF-$\alpha$, or normal saline by intraperitoneal route. Twenty eight days after tumor cell inoculation, metastatic nodules of lung were enumerated and immunohistochemical staining of the subcutaneous tumors were performed with monoclonal antibodies to CD4, CD8, CD16, and E-selectin. In IL-12 treated mice, the subcutaneously implanted Lewis lung tumors were decreased in size and the metastases were also decreased in number compared to control mice. On tumor tissues, increased infiltration of CD4+, CD8+, and CD16+ cells were oberved in IL-12 treated mice compared to control mice. In control mice, E-selectin was absent on tumor vessels, but the expression of E-selectin was increased on tumor vessels of IL-12 treated mice. Administration of TNF-$\alpha$ increased not only the expression of E-selectin but also infiltrations of CD4+, CD8+, and CD16+ cells on tumor tissues. Conclusions: These results demonstrate that IL-12 inhibits tumor growth and metastases through infiltrations of inflammatory cells in mouse model of Lewis lung carcinoma and E-selectin may playa role in inflammatory cell recruitment on tumor tissue following IL-12 administration. Also, TNF-$\alpha$ may have a role as a mediator responsible for the IL-12 induced expression of E-selectin.

The study was performed to assess the antinociceptive efficacy of Korean bee venom(BV) in the rat formalin test. Korean BV was collected using BV collector devices in which an electrical impulse is used to stimulate the worker bee(Apis mellifera L.) to sting and release venom. After collection, whole Korean BV was evaporated until dry using BV collector. Experiments were performed on male Sprague-Dawley rats(weighing 260-270, 6 weeks old). Rats divided into 4 groups, each comprising 8 rats. BV was diluted and amounts of 6 mg/kg body weight(BW), 0.6 mg/kg BW and 0.06 mg/kg BW were tested. BV was subcutaneously injected to produce an antinociceptive effect and the antinociceptive efficacy was evaluated using a rat formalin test. BV was subcutaneously injected into an acupoint(Zusanli, ST36) at 15 min prior to 1% formalin($50{\mu}l$) injection. The antinociceptive effect observed during 60 min following formalin administration. BV produced antinociceptive efficacy from 10 to 60 min after formalin injection. The antinociceptive efficacy of Korean BV showed a dose-dependent response. These results suggest that Korean BV may be a suitable and preferred choice for antinociceptive efficacy in pain management.

Multiple external carotid artery aneurysms with neurofibromatosis are rare. Trauma is the primary cause in the development of aneurysms of the external carotid artery. A 39-year-old female patient was referred to the emergency room because of a headache and a huge lump over the left temporo-parieto-occipital region. The physical examination revealed a huge round mass, $5{\times}15{\times}18cm$, in the left temporo-parieto-occipital region and low set left ear and multiple caf au lait spots in trunk and extremities. The external carotid artery angiography demonstrated multiple aneurysms arising from the superficial temporal artery and occipital artery. A MRI showed a huge hematoma on temporo-parieto-occipital region and postauricular mass suggested of subcutaneous neurofibroma. Embolization followed by surgical resections of those aneurysms and neighboring mass were performed and good result was obtained. We report our case with review of literature.

The recent availability of recombinant human erythropoietin has opened new perspectives in the management of a variety of anemias. Clinical trials have been initiated in several countries using different approaches and methodology. We randomly assigned twelve premature infants(gestational age < 32 week) at high risk of requiring erythrocyte transfusion for anemia of prematurity with either subcutaneous recombinant human erythropoietin or a placebo. Treatment with rHuEPO was initiated at a dose of 100 units/kg day for 3 days a week. All patients were given supplemental oral iron therapy at a dose of 3 mg/kg per day, as tolerated and oral vitamin E at a dose of 25 units per day. Treated and control babies did not differ with respect to weight, hematocrit, overall mean reticulocyte count or rate of growth respectively. However, reticulocyte counts increased earlier in patients given rHuEPO. We conclude that rHuEPO administration is safe and feasible at the dose studied.
