Purpose : The purpose of this study is to make and use monoclonal Ab which reacts with CMV major immediate early(${\alpha}$) protein(p72). Methods : Normal human fibroblast(Foreskin derived) was cultured in Eagle's minimal essential medium(MEM) containing 10% cowfetus serum and mouse chondroblast was cultured in P3X63 Ag8.653(ATCC. Maryland USA) to maintain $5{\times}10^5/ml$ cell counts. CMV(KJHJ90) from congenital CMV infected infant's urine was multiplied and used for Ab making. CMV Ag was injected 4 times, 1 week interval into the peritoneal space of 6~8 weeks old mice. And then lymphocyles and fibroblasts taken from spleen were obtained and conjugated. After the conjugated cell cultured, we chose the cell that had high Ab titer using indirect immunofluerescent method. Results : Among the 28 monoclonal antibodies obtained LPC12 and LPC23 reacted highly with nucleus of AD169 infected cell. Purified AD169 after SDS-PAGE, molecular weight of Ag, which reacted with purified monoclonal Ab, was obtained using Western blotting. Monoclonal Ab of LPC12 and LPC23 clone reacted most highly with 72 kd Ag. Conclusion : LPC12 and LPC23 clonal Ab with AD 169(P63-27) is useful on early diagnosis of CMV infection.

Osteopetrosis is an uncommon hereditary bone condition characterized by a generalized symmetric increase in skeletal density and abnormalities of bone resorption remodeling. In 1904, the first case of generalized sclerosis of the skeleton was reported by $Albers-Sch\ddot{o}nberg$. Osteopetrosis is generally divided into two main type. The infantile(malignant, congenita) type is the most severe form of the disease; It is characterized by skeletal and hematologic abnormalities. The adult(benign, tarda) type which is usually diagnosed in the third or fourth decade of life is limited predominantly to skeletal anomalies and it carries a more favorable prognosis. The recently recognized intermediate form with its mild and variable clinical recessive trait. There is no reported gender or racial predilection. The characteristic feature of osteopetrosis which is an abscence of physiologic bone resorption results in accumulation of bone mass and mainfests skeletal disturbance. Dental finding of osteopetrosis includes delayed eruption, congenitally absent teeth, unerupted and malformed teeth, and enamel hypoplasia. Our report involves a patient with a chief complaint of tooth mobility and delayed eruption. After clinical and radiologic examination, this patient was referred to dept. of pediatrics under the suspicion of osteopetrosis and it was confirmed.

Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and inclose distant metastasis free suwival. IORT is the modality which could increase local control without incressing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988, and performed 53 IORT En patients with gastric cancer. No local failure has been reported by regular follow up so far. Nine cases ($17\%$) of treatment related complicaiton were reported including intestinal obstrution, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo's $25.2\%$ (chemotherapy + operation), Kim's $18\%$ (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500 cGy), external irradiation (--4500 cGy) and extensive chemotherapy(FAM, 5FU + MMC, BACOP).

Bacille Calmette-Gu$\acute{e}$rin (BCG) vaccine is a live attenuated vaccine derived from Mycobacterium bovis. Frequent complications after BCG vaccination are localized ulcer formation and regional lymphadenitis, but there could be rarely severe systemic reactions to BCG vaccine such as osteomyelitis and disseminated BCG infection. Although disseminated BCG infection can be complicated in infants with underlying immunodeficiency after BCG vaccination, it is very unlikely to develop in immunocompetent infants or children. We report a 13-month-old infant who presented with fever, skin nodules, and multiple enlarged lymph nodes 5 months following BCG vaccination. She was diagnosed with disseminated BCG infection by PCRconfirmed M. bovis BCG infection at ${\geq}$2 anatomical sites beyond the region of vaccination. The patient showed no obvious evidence of immunodeficiency as judged on the basis of previous disease history, plasma immunoglobulin levels, B and T lymphocytes counts in peripheral blood, DHR (dihydrorhodamine 123 fluorescence) test and HIV test. She started antituberculous treatment with isoniazid and rifampin, and now, apparently her symptoms have been improved.

Though the occurrence of multiple primary malignant tumor is a rare finding but the reported cases of it has increased in recent years. We collected multiple primary cancer of different organ, tissue and the multicentric origin of bilaterally paired organs. This paper reports 6 cases of multiple primary malignant tumors which were experienced at Yeungnam university hospital in Taegu during the past 2 years with review of journals. The results were as follows. 1. The incidence of multiple primary cancer was 0.31% for 2 years(1987-1988). 2. The ratio between male and female was 1:1 and mean age of incidence was 54.1 years. 3. The ratio between synchronous and metachronous(interval more than 6 months) was 1:1. 4. The time interval between first and second cancer was average 2.7 years in metachronous cases. 5. The most frequent involved organ was stomach, breast and colon in order of frequency. 6. The incidence of familial cancer associations was found in one out of 6 cases. 7. The test of DNCB, multi test CMI and ratio of T4 to T8 were performed in 4 cases but there was no definitive evidence of abnormality. We concluded that every effort should be made to discover the presence of synchronous malignancies in the patients who are being treated for a known tumor, and also special care should be given to detect new metachronous lesions is required.

Purpose: We analyzed the clinical results after arthroscopic treatment in acute pyogenic arthritis of the knee. Materials and Methods: From July 2000 to January 2005, we reviewed 16 cases(15 patients) of acute pyogenic arthritis of the knee on which arthroscopic treatment was done. The mean age was 61.9 years and the mean follow-up period was 30.5 months. There were 8 cases with diabetes or degenerative osteoarthritis and 14 cases with acupuncture or intraarticular injection history. Results: Causative organisms were identified in 7 cases. The average postoperative antibiotics were used intravenously for 25.5 days and per orally for 22.5 days. There were 11 complications; 5 cases of partial ankylosis, 2 cases of secondary arthritis, 1 case of chronic osteomyelitis and 3 cases of death. Patients with over 3 week immobilization had higher rate of stiffness of knee joint(p=0.032) but there was no significant difference between the symptom to treatment duration and the incidence rate of complications(p=0.293). The cases of which the causative organism was detected had higher incidences of complications(p=0.034). Conclusion: The incidence of joint stiffness was higher in the patients of longer immobilization. More complications were detected in the cases of which the causative organism is detected.

Acute disseminated intravascular coagulation (DIC) associated with gastric cancer is not common and has short survival of 1 to 3 weeks. Systemic chemotherapy in spite of hematologic unstability for gastric cancer may prolong survival time. A 47-year-old woman who complained of dyspnea, vaginal bleeding and easy bruisibility was diagnosed to stage IV gastric cancer with acute disseminated intravascular coagulation based on the laboratory data. She also had multiple bone metastases and bone marrow involvement. This is the first case treated with combination chemotherapy of irinotecan and cisplatin for advanced gastric cancer complicated by disseminated intravascular coagulation at the time of diagnosis, With systemic chemotherapy, some of the bleeding symptoms and the DIC process improved, even not completely recovered. However the patient died of disease progression and survival time was 12 weeks.

The ectopic eruption is defined as abnormal eruption which gives to displacement of the teeth and abnormal root resorption of adjacent teeth. The prevalence of ectopic eruption is reported to vary 2~6%, most of them are in the maxilla. Etiologic factors include narrow maxilla, large maxillary teeth, inclined eruption path of the first molar, retruded position of the maxilla and hereditary factor. Irreversible ectopic eruption where the second primary molar is lost often causes mesial tipping and rotation of the permanent molar, unfavorable occlusion and space deficiency for the second premolar. Ectopically erupted teeth should be treated early to maintain normal development of the dentition, harmony of facial growth and occlusal support. The method of the treatment are classified as follows : appliances that is positioned at the contact point for unlocking and the distal movement, fixed appliance that is connected to more than one tooth, and occlusion guiding method after disking or extraction of the second deciduous molar. A case report of a patient with bilaterally ectopic eruption of maxilla and mandible first permanent molar was present. Also, the patient who had experienced the chronic myelogenous leukemia, show various dental developmental complications. The ectopic eruption was treated with a Halterman appliance that was a effective way of correcting of ectopic eruption of the permanent first molar.

Pyknodysostosis(PKND) is a rare sclerosing bone disorder that has an autosomal recessive trait, also known as Toulouse-Lautrec syndrome. Deficiency of the cathepsin enzyme K in the osteoclasts of PKND patients results in continuous endosteal bone deposits without osteoclastic resorption or remodeling. This causes a generalized increase in sclerosis and fragility of bones. Osteomyelitis in the mandible and recurrent fracture of the long bones are characteristic complicatons of PKND. The patients present typical features of PKND, such as short stature under 150 cm, open cranial suture and fontanelle, club-shaped phalanges, and underdevelopment of midface. This is a case of a 7-year-old girl with PKND, who visited our clinic with the chief complaint of anterior Open-bite and generalized crowding. The patient had been diagnosed as PKND by an orthopedist and manifested characteristic clinical and radiographic features, such as open cranial suture and fontanelle, obtuse madibular gonial angle, frontal and occipital bossing, grooved palate, club-shaped phalanges, and short stature. Orthodontic treatment was not considered because patients with PKND show abnormal bone resorption and remodeling. Instead, removal of deciduous teeth near exfoliation and TFA were performed, and periodic check-up is planned to maintain good oral hygiene.

A 66-year-old woman was transferred to our hospital due to her right breast cancer. Preoperative breast MRI shows 1.9 cm malignancy on her right breast (cT1N0M0) and incidentally found osteosclerotic change of left coststernoclavicular region. Bone scintigraphy showed hot uptake and the possibility of bone metastasis was not excluded. However, because the bone metastasis is not common in early stage cancer and the costosternoclavicular region is not common site, other possibility should be considered. SAPHO syndrome can be diagnosed even in the absence of dermatosis when there is an axial or appendicular osteitis and hyperostosis, especially in costosternoclavicular region. Though breast imaging specialists are not accustomed to this disease entity, awareness and diagnosis of the SAPHO syndrome can help differentiate bone metastasis.
