We report a case of pigmented spindle cell nevus occurred in a 4-year-old girl. The lesion was well-demarcated, 2.5 x 3mm sized black macule on the left thenar area. The histopathologic findings of excisional biopsy specimen revealed the prociferation of uniform spindle-shaped pigmented melanocytes at the dermoepidermal junction and sharply definded lateral margins.

In order to discover difference that may exist in quantity of medical care services, length of stay and hospital changes between insured and non-insured patients, records for primary Cesarean section patients discharged between July 1978 and June 1980 from a university hospital were examined. In addition, Cesarean section rates among the total deliveries for a two-year period between the groups were studied. The results showed that volume of services was greater and length of stay was longer among the insured, however, charges were higher among the non-insured. Cesarean section rates were statistically significantly different between insured and non-insured patients for every age group except the group of 35 or more.

PURPOSE: To evaluate the radiological patterns of vascular invasion in peripheral cholangiocarcinomas. MATERIALS AND METHODS: Hepatic arteriography and portography in 20 cases with cholangiocarcinoma including 12 cases with anglographic CT were retrospectively analized. RESULTS: The arteriography showed no arterioportal shunt, hypertrophy of tumor vessel, or tumor staining extending to central portion of the mass in all cases. However, doughnut shaped peripheral tumor staining was seen until late hepatogram phase in 12 cases and compensatory hyperperfusion around the mass was seen in six cases(eight cases if include arterial CT). Encasement of tumor vessel was seen in 12 cases, and hypertrophy of feeding vessel in nine cases. On portogrphy, the filling defect on segmental portal branch could be demonstrated only in 11 cases. Shape of the portal defect was tapered narrowing in six cases, abrupt narrowing in two cases but intraluminal nodular filling defect was not seen. Remainning three cases were difficult to define the shape. On seven cases of CT during arterial portography, three cases showed mass shaped defect and four showed segmental defect but three of them could demonstrate the partially preserved portal flow in defective portal area. CONCLUSION: Hepatic arteriography in peripheral cholagiocarcinoma showed no evidence of hypertrophy of tumor vessels and tumor stain extending to central portion but peripheral staining on late hepatogram phase and compensatory hyperperfusion could be seen. Portal vein was more commonly involved through perivascular connective tissue invasion rather than by direct extension into the portal lumen.

We evaluated the characteristics of HMB-45 monoclonal antibody(MoAb) and compared it with a polyclonal anti-S-100 antibody in immunohistochemical staining of 22 primary melanomas of the skin ; 13 acral lentiginous melanomas(ALM), 3 superficial spreading melanomas(SSM), 4 lentigo maligna melanomas(LMM), 3 nodular melanomas(NMM). All speimens were formalin-fixed and paraffin-embedded, and were studied with the avidin-biotin-peroxidase complex technique. The results can be summarized as follows : l. In all tissue specimens, all or some of the melanoma cells in the dermis reacted with HMB-45 MoAb and anti-S-100 protein. 2. HMB-45 MoAb is more sensitive in detecting malignant melanoma cell heterogeneity t,han anti-S-100 protein. 3. Melanoma cells within the epidermis in 6 of 12 ALMs and 3 of 4 LMMs did not react with anti-S-100 antibody, whereas most melanoma cells within epidermis of 12 ALMs and 4 LMMs reacted with HMB-45 monoclonal antibody. These results indicated that immunohistochemical staining with HMB-45 MoAb and anti-S-100 protein is very useful in the study of biologic behavior of malignant, melanoma.

Two typical cases of epithelioid sarcoma were examined by immunohistochemical stain using antibodies to epithelial membrane antigen, carcinoembryonic antigen, vimentin and cytokeratin. Both cases showed positive reactivity for the four kinds of antibodies. These results point to the fact that epithelioid sarcoma simultaneously expresses epithelial markers and characteristic mesenchymal phenotypes. Epithelioid sarcoma appears to be a tumor derived from a multipotential mesenchymal cell with multidirectional differentiation.

STUDY DESIGN: This study was undertaken to document the effect of TGF-beta 1 and TGF-beta2 on the proliferation of lumbar facet joint capsule. OBJECTIVES: To study the effect of TGF-beta1 and TGF-beta2 on the proliferation of lumbar facet joint capsule and their proliferation mechanism. SUMMARY OF LITERATURE REVIEW: TGF-beta1 and TGF-beta proliferated mesenchymal tissue . This proliferatine mechanism was involved of PLC-gamma- 1 and tyrosine kinase in signalling. MATERIAL AND METHODS: Three lumbar facet joint capsule was cultured in DMEM-20 media. Its proliferatine and inhibited effect was studied under the metabolic inhibitors and trasnsforming growth factors . RESULTS: TGF-beta1, and TGF-beta2, increased cell proliferation dependent on time and dosage. Both of TGF-beta1, and TGF-beta 2, specific antisense oligonucleotide blocked tile autoc.me effect of growth factor, PLC-gamma-1 specific antisense oligonucleotide inhibited the effect of TGF-beta 1, and TGF-beta2, Genistin inhibited the effect of TGF-beta 1, and TGF-beta2, in time and dosage dependent manner. CONCLUSION: The cell proliferation of lumbar facet joint capsule was involved in PLC- gamma-1 and tyrosine kinase in signalling.

Adhesion around tendons of the hand and wrist and subsequent limitation of motion, is one of the major complications after tendon surgery. In addition to the tendon surgery such as tendon repair or graft, infection, open reduction of fracutres, and burn scar contracture could be the casuses of tendon adhesion. Tenolysis and adequate postoperative rehabilitation program, has been proved to be effective in preventing of adhesion, whatever the cause may be, if its continuity is maintained. In order to evaluate the efficiency and problems of tenolysis, we reviewed 37 fingers of 31 patients who had been treated by tenolysis at Seoul National University Hospital from 1981 to 1991. There were 20 men and 11 women, and the average age was 28.2 years(9-45 years). The causes of adhesion were various; 24 fingers(64%) after tendon repair or tendon graft, 3 fingers(8%) after infection, 4 fingers(10%) after treatment of fracture, 4 fingers(10%) after burn scar contracture, and the other 2 fingers(5%) after curettage of enchondroma. Involved tendon were flexor tendon in 28 fingers and extensor in 9. The average duration of follow-up was 17 months(13 months to 4 years). Active motion of involved finger was started within 2 days after operation. The Total Active Motion(TAM) after operation was average 213°(100°-260°), compared to 123°(40°-180°) before operation. According to Strickland formula which was modified by us, the postoperative results were excellent in 17 fingers, good in 9 fingers, fair in 6 fingers and poor in 5 fingers. In 24 cases who had tenolysis after repair or graft, 19 case(79%) were rated as excellent or good. But in 7 cases whose causes of adhesion were infection or burn scar contracture, only 3 cases(42%) were rated as excellent or good. Compairing the results between younger(less than 30 years of age) and older(more than 30 years of age) group, the younger group showed excellent and good in 8496 and the older group in 41%, The complications were tendon rupture in 3 fingers and minor infection in 2 fingers, respectively. In summary, tenolysis was considered as a useful procedure to improve function of tendon bound down in scar tissue. And the results were better in younger age group(p < 0.05) and in previous tendon repair or graft(p < 0.05) group.
