The ankle joint plays important biomechanical role in erect position or ambulation. The ankle injury includes bony structures with articular surface, ligaments and soft tissue injury. So the goal of treatment is anatomical reduction of ankle mortise. Fifty two patients of ankle fractures which were admitted and treated in Seoul Adventist Hospital from January, 1980 to December, 1984, were analysed in the clinical and radiological aspect. The results obtained from this study were as follows; l. Of the 52 cases, male was 39 cases(75.0%) and female was 13 cases(25.0%). The average age of the patients was 33 years with range from 18 years to 75 years. 2. The most common cause of injury was traffic accidident. Nexts were fall down, sports injury, slip down and industrial injury in orders. 3. The most common type of the ankle fractures, according to the classification of Lauge-Hansen, was supination-external rotation type(40.4%). 4. 36 cases(69.2%) were treated with open reduction and internal fixation and 16 cases(30.8%) were treated with closed reduction. Poor outcome seemed closely related to the severity of the injury and degree of fracture displacement. 5. Accurate reduction and rigid internal fixation of the lateral malleolus without shortening was important factor. Classification of Lauge-Hansen was useful in the diagnosis and treatment of the ankle fractures.

5.Effects of Normal Fibroblasts and Peripheral Blood Mononuclear Cells on Squamous Cell Carcinoma Cell Line ( SCL - 1 ).

Many carcinomas have an active mononuclear cell infiltrates surrounding tumor. Various in vitro assays have shown that cellular constituents of peripheral blood mononuclear cells(PBMC) can alter growth of carcinoma cell line. Author compared the effects of normal fibroblasts on squamous cell carcinoma cell line(SCL-1) along with those of sctivated and/or nonactivated PBMC on SCI 1 using a skin equivalent system. This system prevents direct cellular contact by growing SCL-1 on an overlying Millicell-HA membrane and normal fibroblast or supernatants of PBMC in a lower chamber. Normal fibroblasts enhanced the outgrowth of SCL-1 and induced a more organized phenotype of SCL-1. Supernatants from nonstimulated PBMC suppressed outgrowth of SCL 1, and concanavalin A stimulated PBMC supernatants alterd rnorphology of cultured SCL-1 from a disorganized phenotype to a more organized phenotype. It is concluded that fibroblasts and PBMC may affect the growth and differentiation of SCL-1 via their mediators(cytokines)

Forytfour-year-old female inpatient, who was gravely ill, developed vesicobullae on the greenish patches surrounded by narrow red to brown halo in the left lower extremity. Two years ago, she had treated by surgical operation and radiation therapy for cervix cancer. Blood and bullous fluid cultures showed Pseudomonas aeruginosa. She developed gangrenous and mummificated skin lesions after septic shock therapy but died due to disseminated intravascular coagulation.

The effect of long-term topical application of corticosteroids on rat cutaneous mast cells was examined under the light microscopy. Two potent corticosteroids, 0.05% clobetasol-17-propionate and 0.25% desoxymethasone, produced a remarkable decresse greater than 50% of pretreatment mast cell number by two weeks. Wheress a less potent corticosteroid, 0.1% hydrocotisone-17-valerate, produced a remarkable decrease greater than 50% of pretreatment mast cell number by four weeks. All corticosteroids produced a remarkable decrease greater than 80% of pretreatment mast cell number by six weeks. These results suggest that long-term topical application of corticosteroids may have the deleterious effects on cutsneous mast cells.

BACKGROUND: T cell mediated immune destruction is an important mechanism of liver injury in patients with chronic hepatitis C. Serum levels of soluble interleukin-2 receptor(sIL-2R) seem to serve as a marker for the T cell activation and progressive liver injury, This study examined serum levels of sIft-2R and hepatitis C virus (HCV) RNA in patients with chronic HCV infection to determine the correlation with the severity of chronic hepatocellular damage. METHODS: Serum levels of sIft-2R in 73 patients with HCV infection (chronic hepatitis 52, liver cirrhosis 9, hepatocellular carcinoma 12) and 40 healthy controls were measured by sandwich enzyme immunoassay (CELLFREE, T Cell Sciences, USA). HCV RNA was quantified by QUANTIPLEX(TM) HCV RNA 2.0 assay (Chiron, USA) with duplication. This assay is a sandwich nucleic acid hybridization procedure using branched DNA amplification for the quantitation of HCV RNA. RESULTS: The sIL-2R levels of 52 patients with chronic hepatitis (591.4+/-238.7U/mL), 9 with liver cirrhosis(949.4+/-721.9 U/mL), and 12 with hepatocellular carcinoma (1,167.4+/- 554.4 U/mL) were significantly higher than those of healthy controls(370.8+/-71.8 U/mL) (p<0.001). A progressive and significant increase occurred in sIL-2R levels with chronic hepatitis C, liver cirrhosis and hepatocellular carcinoma (HCC) in order (p(0.001). The HCV RNA was detected in all patients and the means of HCV viral load were 3.3 MEq/mL in chronic hepatitis, 2.8 MEq/mL in cirrhosis, and 3.7 MEq/mL in HCC. There was no significant correlation between HCV RNA and the severity of liver injury in chronic HCV infection. There were no correlations among sIL-2R, HCV RNA and serum ALT. CONCLUSIONS: These results suggest that chronic hepatocellular injury by HCV progress mainly by T cell mediated immune response, not by direct cytopathic injury. Also, sIL-2R can be useful as a marker in monitoring the patients with HCV infection at high risk of getting HCC.
