Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

BACKGROUND: Sun exposure and therapeutic irradiation have been shown to induce alterations in extracellular matrix (ECM) proteins, including elastin, glycosaminoglycan and collagens. The integrity of the connective tissue mainly depends on balanced rates of matrix synthesis and degradation of the extracellular matrix. Therefore, matrix metalloproteinases (MMPs) may be involved in ultraviolet irradiation (UVR)-induced alterations in ECM proteins. OBJECTIVE: To evaluate the effects of UVA as well as UVB irradiations on ST-1 gene expression in cultured human skin fibroblasts. METHODS: After exposure of different doses of UVA and UVB on cultured human skin fibroblasts, we examined the expression of ST-1 gene by Northern blot analysis, chloramphenicol acetyltransferase (CAT) assay with CAT construct containing AP-1 binding site. Additionally, we carried out the gel mobility shift assay to investigate the effects of UVR on the DNA-binding activity of AP-1. RESULTS: After UVR on fibroblasts, the steady-state levels of ST-1 mRNA were in-creased in response to UVA and UVB by 2.5-fold and 4.2-fold, respectively, as compared with controls. Similar results were obtained by CAT assay showing that CAT activity increased as the UVA and UVB doses increased. Furthermore, gel mobility shift assay demonstrated that both UVA and UVB increased AP-1 DNA binding complexes. CONCLUSION: UVB as well as UVA up-regulated ST-1 gene expression at transcriptional levels in vitro. We speculate that modulation of MMPs, including ST-1, gene expression by UVR may contribute to the connective tissue damage related to photoaging and other photocutaneous disorders.

We report a case of primary cutaneous cryptococcosis on Rt. forehead and perioral area of 57 year old woman with non-insulin dependent diabetes mellitus and Lt. cerebral infarction. She had large ulcers with yellowish purulent exudates on Rt. forehead and perioral area for 2months. A histopathological examination from the lesion showed numerous encapsulated, round spores and the organisms were identified as Cryptococcus neoformans in a series of fun-gal studies. The patient received a 5-week course of IV and oral fluconazole with resolution of her skin lesion. The patient is free of any lesion several months after completing therapy. This experience supports the use of fluconazole as initial and single therapy in primary cutaneous cryptococcosis.

Cervical spine injuries are increasing recently due to increasing traffic accidents. Many patients have been treated with cervical laminectomy but stabilization of the cervical spine has been neglected as a part of the treatment. 30 patients with cervical spine injuries who were admitted to our hospital from January 1, 1973 to December 31, 1978 were evaluated. The following observations were made: 1. The ratio between male and female was 2:1 and the majority(43%) were found in the 4th decades. 2. The common causes of cervical spine injuries were traffic accident(40%) and falls(33.3%). The most common site of the lesion was the 5th and 6th cervical spine level (33.3%). 3. Among 30 cases, 10 cases(33.3%) had complete paralysis, 12 cases(40%) incomplete paralysis, 6 cases (20%) had nerve root injury and no neurological change is 2 cases. 4. The mechanisms of cervical injuries were classified morphologically and flexion-rotation injuries (55.5%) were the most common. 5. We evaluated the results of treatment neurological & radiographically. In complete paralysis, there was no neurological improvement and cervical kyphosis increased after laminectomy. In incomplete paralysis and nerve root injury, anterior fusion showed slight neurological recovery but mild cevical kyphosis and displacement of the graft were observed. In posterior fusion or cast immobilization, we had a satisfactory result with a high fusion rate and normal cervical curvature. 6. lt is impossible to compare anterior interbody fusion with posterior fusion for neurological recovery. For early mobilization and rehabilitation, we emphasize early stabilization by anterior or posterior fusion according to the mechanism of injury.

Enlargement of bone tunnels has been noted on plain X-rays following arthroscopic ACL reconstruction. The cause of this widening is unclear, but it has been hypothesized that it may be due to either mechanical or biological cases. Ishibashi et al. reported anatomical proximal fixation resulted in the most stable reconstructed knee, with increasing instability as the level of fixation moved away from the tibial plateau. The purpose of this study is to determine if any difference exists in the amount of enlargement of the femoral tunnel following arhotoscopic ACL reconstruction with position of interference screw fixation and instability, and to know the factors which affected to the enlargement of the femoral tunnels. Total 39 patients were retrospectively reviewed for tunnel measurements radiologically at one year post-operation. (27 patients received bone-patellar tendon-bone autograft, 12 patients received bone-patellar tendon-bone autograft and Kennedy LAD-ligament augmentation device). The surgery was performed using an arthroscopic single and double incision technique. AP and lateral X-rays were obtained and the tunnels were measured by two independent observers using a digital caplper. The measurements were made at the widest part of the tunnel. Correction for magnification was performed by comparing the measured width of the interference screw used for fixation of the graft with its actual width. Statistical analysis was performed using a one-way analysis of variance(ANOVA) and t-test. 1. Radiographic tunnel enlargement of femoral side was average 2.42 mm (bone-patellar tendon-bone autograft : 2.36 mm, Kennedy-LAD and autograft : 2.56 mm)(p>0.05). 2. According to the position of the interference screw, the femoral tunnel enlargement were 2.25 mm in anatomical fixation, 2.40 mm in mid-tunnel fixation, 2.62 mm in mid-tunnel fixation, 2.62 mm in outer-tunnel fixation(p < 0.05). 3. The femoral enlargement according to the overall results(Clancy, 1982) were 2.39 mm in above good result group and 2.50 mm in below fair result group(p < 0.05). Tunnel enlargement group of femoral side was related to a distance between femoral articular surface and the position of interference screw. We conclude that femoral tunnel enlargement following arthoscopic bone tendon-bone ACL reconstruction is related to the mechanical effect rather than the properties of grafts and the clinical results.

10.MUC1 from the Mucin Family as Potential Tools in Breast Cancer Immunotherapy.
Heung Kyu PARK ; U Hyoung SEOV
Journal of Breast Cancer 2009;12(3):125-133
Many breast cancer patients develop minimal residual disease that becomes resistance to treatments, and finally are faced with relapse and progression of disease. Currently, immunotherapy has become a potential therapy in treating minimal residual disease and preventing cancer occurrence. Cancer vaccines provide a unique therapeutic modality in that they initiate a dynamic process of activating the host's own immune system. A lot of tumor specific antigens as a target of immune system were identified and some have been applied for cancer vaccine. Mucin 1 (MUC1) oncoprotein, which is overexpressed in breast cancer in contrast with normal mammary tissue, is one of the first tumor antigens shown to be a target for human tumor-specific T cells and thus a valid target for immunotherapy. MUC1 is a high-molecular-weight glycoprotein rich in serine and threonine residues that are O-glycosylated. MUC1 is expressed on glandular epithelia and on epithelial tumors. But, tumor MUC1 differs from normal MUC1 by modified glycan side chains. Over-expression and aberrant glycosylation of MUC1 antigen by epithelial tumors results in endogenous antibody responses in cancer patients to MUC1 antigen. This finding has led to the identification of MUC1 derived peptide epitopes that induce T-cell responses. MUC1 based clinical trials have used peptides, protein, DNA, pulsed dendritic cells, or glycopeptide. This review will summarize the potential utility of breast cancer immunotherapy of MUC1, as well as the structure and function.
