HIV-1 p24 was cloned into multiple cloning site of pMV261, extrachromosomal expression vectors carrying BCG replication origin and BCG-specific heat-shock promoter, and then introduced into BCG and E. coli. Western blot experiments showed that the p24 efficiently expressed in recombinant BCG (rBCG), but not in E. coli. Recombinant p24 expression induced by a single heat-shock of rBCG was maintained longer than 3 weeks. Immunoblot experiments with intact rBCG did not show any distinctive positive signal, suggesting that the recombinant protein was not secreted or exposed at the surface of BCG. The guinea pigs immunized with live rBCG showed delayed type hypersensitivity (DTH) by the systemic area as well as an effective humoral immunity, suggesting that tbis rBCG is believed to elicit eKcient immune responses against p24, even though the expression is restricted only in the cytoplasm as reported previously with other antigen. These results demonstrate that BCG can be developed as a live recombinant vaccine vector against a broad spectrum of infectious disease.

OBJECTIVE: To understand the pathogenesis of adenomyosis through the immunohistochemical staining with bcl-2 and matrix metalloproteinase-9 (MMP-9) antibody. METHODS: We selected 45 cases of adenomyosis among the uterine specimens that were extirpated surgically due to benign gynecologic problem. Immunohistochemical staining to the myometrial tissue was performed using anti-bcl-2 and anti-MMP-9 antibodies. Staining was qualitatively assessed in terms of extent and intensity. RESULTS: There were 32 cases of proliferative phase and 13 cases of secretory phase depending on the date of endometrium. Anti-bcl-2 stained 81.3% (26/32) compared with anti-MMP-9 stained 6.3% (2/32) in the glandular tissue of the proliferative phase (p<.001). In the secretory phase, anti-bcl-2 92.3% (12/13) and anti- MMP-9 7.7% (1/13) respectively (p<.001). In the stromal tissue of the proliferative phase, anti-bcl-2 stained 62.5% (20/32) compared with anti- MMP-9 stained 6.3% (2/32) (p<.001). In the secetory phase, anti-bcl-2 84.6% (11/13) and anti-MMP-9 15.4% (2/13) (p<.001). CONCLUSION: The adenomyosis may be developed from simple invagination and cellular proliferation of endometrial tissue, not caused by myometrial infiltration of endometrial tissue.

BACKGROUND/AIMS: The prognosis of primary hepatocellular carcinoma is extremely poor because of its large size, portal vein thrpombosis, extrahepatic metastasis and underlying liver cirrhosis. The aim, of this study is to evaluate the usefulness of ultrasound screening test for early detection of hepatocellular carcinoma in high-ridk populations. METHODS: We analysed 119 patients who were diagnosed with hepatocellular carcinoma by ultrasonography screening test in Yonsei University Severance Hospital from the period of January 1990 to December 1996. RESULT: The mean follow-up duration to the diagnosis of hepatocellular carcinoma was 30 months (range 3-75). The number of patients with single lesion was 89(75%). The mean diameter of the tumor was 3.0 cm (range 1-10) , 82 patients (70%) had masses measured less than 3cm in diameter. The Number of patients with elevated serum alphafetoprotein level above 400ng/ml was 29(25%). The median survival was 28 months in screening group, significant compared with 7 months in control group (p<0.001). CONCLUSIONS: Ultrasound follow-up in high-ridk group of hepatocellular carcinoma mede it possible to detect small tumors in a high percentage of cases. This may lead to an increase in the number of potentially curable tumors and hence an increase in the overall survival rate. So ultrasound screening test is important in the high-ridk group of hepatocellular carcinoma.

The teratogenic effects of alcohol have been recognized in fetal alcohol syndrome (FAS). FAS is a collection of signs and symptoms seen in some children exposed to alcohol in the prenatal period. An 8 month-old-male with an alcoholic mother was diagnosed as a case of FAS according to the following : 1) early-onset intrauterine growth retardation and persistent postnatal growth failure 2) psychomotor retardation 3) craniofacial dysmorphism. Early diagnosis and continued education are advantageous at all levels, benefiting both the individual and all of society. We present this case with a brief review of related literatures.

This year, the Korean Society of Nuclear Medicine (KSNM) is celebrating its 60th anniversary. Treatment, as well as diagnosis, has played a very important role in the development of nuclear medicine. Since I-131 was used for thyroid therapy in 1959, other radionuclide therapy is still being used, and attempts to use new radionuclide are increasing. In this review, we briefly summarize and introduce the therapies such as radioimmunotherapy, transarterial radioembolization, radionuclide therapy for neuroendocrine tumors, peptide receptor radionuclide therapy, control of metastatic bone pain, radiation synovectomy, radionuclide brachytherapy, alpha particle therapy, and boron neutron capture therapy, which has been being attempted so far in the field of nuclear medicine.

Myelodysplastic syndromes (MDS) are a group of refractory anemias resulting from a clonal stem cell disorder often associated with cytogenetic abnormalities. There is increasing recognition of immunological abnormalities in patients with MDS, including defective B- and T-cell function, hyper- or hypogammaglobulinemia and monoclonal gammopathy. MDS have been associated with Sjogren's syndrome, polymyalgia rheumatica, relapsing polychondritis and systemic lupus erythematosus. Although there may be various rheumatologic features, including acute arthritis in MDS, chronic inflammatory arthritis is uncommonly combined. There have been a few reports that described cases of rheumatoid arthritis (RA) concurrent with MDS, but advanced rheumatoid arthritis with typical joint deformities has rarely been reported. We report a case of rheumatoid arthritis with atlantoaxial subluxation combined with refractory anemia in a 31-year-old woman.

Cap polyposis is extremely rare in children. We report a case of an 11-month-old male infant who visited our hospital because of rectal prolapse and small amount of hematochezia lasting several days. He also had an epidermal nevus in the sacral area. Colonoscopy showed erythematous, multilobulated, circumferential, polypoid lesions with mucoid discharge from the rectum. He was diagnosed with cap polyposis by endoscopy and histologic examination. He was treated with surgical resection, and was closely followed up. In the relevant literature, there is no report of cap polyposis in an infant. We report the first case of cap polyposis in the youngest infant.

PURPOSE: To evaluate the incidence and risk factors of ipsilateral reamputation after lower limb amputation in the patient with diabetic foot lesions. MATERIALS AND METHODS: Between May 2005 and June 2009, 88 patients who underwent lower limb amputation were analyzed. Group 1 consisted of 73 patients who didn't have a ipsilateral reamputation after lower limb amputation and group 2 consisted of 15 patients who underwent reamputation. We compared several factors between two groups, such as age, gender, BMI, ABI, Wagner classification, wound culture, site of amputation, vascular surgery, the period of diabetes mellitus, chronic renal failure. RESULTS: Fifteen (17%) of 88 patients had a ipsilateral limb reamputation and 13 patients (87%) of them underwent reamputation within 6 months. When we compared the two groups, average age was 59.3 (range, 48-74 years); 62.9 (range, 44-78 years). Age was significantly associated with reamputation rate (p=0.02) and no reamputation after initial amputation above ankle joint was found. Other factors did not show statistically difference between both groups. CONCLUSION: There were no significant difference between diabetic limb amputation and reamputation group in our concerned risk factors except age and amputation level. There should be careful consideration when determine level of amputation in diabetic foot lesions especially in elder patients.

Fibromatoses comprise many different entities of well-differentiated fibroblastic proliferation with variable collagen production and form a firm nodular mass. Abdominal fibromatosis is distinguishable from other forms of fibromatosis because of its location and its tendency to occur in women of childbearing age during or following pregnancy. Abdominal fibromatosis in children is an extremely rare condition. A 15-month-old boy presented with an abdominal wall mass that had recently increased in size. Mass excision was perfomed. The tumor was 4.3x4.1 cm and partly circumscribed. Histologically, the tumor was composed of parallel long fascicles of spindle-cells with a uniform appearance. The edges of the resected mass were infiltrative, and the surgical margins were positive. Mitotic figures were <1/10 high power fields. No cellular atypia or necrosis was present. The tumor cells were positive for vimentin and nuclear beta-catenin staining.

BACKGROUND: The early stage of Alzheimer disease might show early memory impairment with normal general cognitive function. Our study aimed to investigate elderly with normal Korean version of mini-mental state examination (K-MMSE) score and recall score of 0 for 1 year. We predicted that the patients would show different characteristics and would progress more rapidly compared with normal controls. METHODS: This study was based on the data from complete enumeration survey of Mapo-gu Regional Center for Dementia in 2009. We divided all subjects into three groups: subjects with normal K-MMSE scores and recall score of 0 were group 1-1 (n=152), subjects with abnormal K-MMSE scores were group 1-2 (n=64) and subjects with normal K-MMSE scores and recall score of 1 to 3 were group 1-3 (n=941). We compared basic demographics and social characteristics among the three groups. After 1 year (2010), the subjects in group 1-1 (90 out of 152) underwent follow-up examinations for dementia diagnosis. They were also divided into three groups (2-1, 2-2, 2-3) according to K-MMSE and recall scores. RESULTS: Group 1-1 showed different baseline characteristics compared with normal controls. After 1 year, 25.5% (23 out of 90) of the group 2-1 were diagnosed as mild cognitive impairment (n=16) or dementia (n=7). CONCLUSION: Our study suggested that subjects with normal K-MMSE scores but recall score of 0 are not entirely "normal". Further detailed evaluation might be needed if memory impairment is suspicious although the K-MMSE scores are within normal range.
