The Beta-2-microglobulin is the part of light chain of human histocompatibility antigen (HLA). This protein can be observed in most of the human nucleated cells. Some of reports indicated that the Beta-2-microglobulin was lost completely or partially in the malignant or premalignant lesions. Observations on presence of Beta-2-microglobulin were made on 24 cases of malignant, premalignant and benign epithelial umors and 6 cases of normal or non-neoplastic epithelial lesions in the skin, using PAP method. The PAP method. 1) Normal epidermis and no-neoplastic cutaneous lesions (chronic non-specific dematitis, actinic change of skin with pseudoepitheliomatous hyperplasia) showed strong positive staining along the cutaneous epithelial cytoplasmic surface for Beta-2-microglobuin in all 6 cases. 2) Benign cutaneous tumors (keratoacanthoma, squamous cell papilloma and pigmented nevus) showed similar strong positive staining for Beta-2-microglobulin along the epithelial cell surface in 4 out 6 cases. Remaining 2 cases were out of 4 pigmented nevus, which showed weakly or pretty weakly staining. 3) Premalignant cutaneous lesions as solar keratosis showed generally weak positive staining along the epithelial cytoplasmic surface in all 4 cases. 4) Malignant cutaneous tumors (basal cell carcinoma, squamous cell carcinoma, Bowen's disease and malignant melanoma) showed mostly negative staining along the surface of epithelial cells for Beta-2-microglobulin, in 8 out of 14 cases. Remaining 6 cases showed slightly weak or patchy positive staining. As above observation, the presence of Beta-2-microglobulin in cutaneous epithelial lesions using PAP method could be indicated as one of good differential tool for histopathologic diagnosis in cutaneous malignant lesions.

The unstable pelvic fracture involving sacro-iliac joint produced by excessive force, is relatively rare but causes a multiplicity of complications and presents a major therapeutic problem. The clinical results were obtained as follows: 1. 9 patients out of 16 were in age group between 20 to 29 year, Male and female ratio was 5:3 2. 10 patients out of 16 were produced by traffic accident. 7 patients among 16 were included in vertical shear type and 5 in lateral compression type. 3. There were 44 associated injuries in 15 patients. Fractures in other region were the most common associated injury in 20 and injuries of the genito-uninary system in 8. 4. All of the cases were treated conservatively and their result were excellent or good except 1 patient in pelvic disruption type, who has had paraplegia due to fracture-dislocation of L4-5.

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.

Pigmented villonodular synovitis (PVNS) is a relatively rare condition. The disorder almost always involves a single joint and the knee is most commonly affected. We report on three cases of localized PVNS that involved the patella fat pad and synovium. Diagnostic and therapeutic arthroscopies were performed, and typical findings of localized PVNS were found. Complete resection of the lesions were performed arthroscopically. Arthroscopy can be used as an effective diagnostic and therapeutic tool for identification and resection of intraarticular localized PVNS of the knee.

BACKGROUND: The functional dyspepsia gives rise to such a symptom similar to peptic ulcer without showing a noticeable lesion(e.g, gastric or duodenal ulcer) by endoscopy or upper GI serises, and it has been known that this is about twice as many as the peptic ulcer. However, there is no exact theory about its pathophysiology and it is suggested that multiple factors including genetic, physiologic, psychologic, environmental factors are engaged. Especially, in respect to the occurrence of functional dyspepsia and psychological factors, there have been many clinical studies over the world. But, we still need more studies in this country, therefore, this study has been initiated to give help patients of functional dyspepsia, invest.igating their characteristic traits through MMPI. METHODS: From March to September in 1996, the patients who visited the family medicine out-patients department of St. Marys hospital of Catholic Medical College were sampled in this study. There were 46 patients having a similar symptoms to peptic ulcer without showing pathologic lesions by endoscopy. Through an interview and some basic tests, the 41 controls who had no dyspeptic symptoms and were not affected to a noticeable physical or physiological disorders were selected for the normal reference group. The standardized MMPI of our country was applied to the whole object groups to get a result. Then each average value of the measure(mean T-score) was calculated, and the differences of the average value were analyzed by the t-test and chi-square test. And the psychological pattern analysis was done. RESULTS: In demographic aspects, there were no significant differences between the two groups. The mean T score for each measure of the two groups falls within the normal ranges with their values being of between 30 to 70. And the average of L, F, and K measure, known as the validity measure, did not give a significant differences between the two groups. The measure of Hs, D, and Hy have appeared significantly high in the patients group(p<0.01) and the Pd measure, too(p<0.05). While Mf, Pa, and Ma measure have not shown a significant differences, Pt, Sc, and Si measure have very significant differences(p<0.01). CONCLUSIONS: In the patient group with the functional dyspepsia, the measures of Hs, D, and Hy where they indicate a neurotic pattern have shown a very significantly high point as well as those of Pd, Pt, Sc, and Si where they indicate a psychotic pattern. This reveals that in the group of the functional dyspepsia neurotic or psychotic trends to attribute. However, it is very hard to define the characteristics of a group with just one test, so further study with more variable test will be necessary.
