Standard plaque assay using agarose-overlay has long been used for titration of many infectious virus particle. Plaque assay for the titration of varicella-zoster virus and its live vaccine requires three intermittent agarose overlay to visualize plaques. Overall procedure of the assay takes at least nine days from virus inoculation and microbe contamination including fungi is frequently accompanied during incubation period. We studied whether an immunofocus assay in conjunction with peroxidase-mediated immunohistochemical reaction may replace the standard plaque assay for the virus titration by comparing the two methods. A linear relationship was observed between number of foci and virus dilution. The number of foci in a given dilution of virus appeared a little higher than counted plaques formed in standard plaque assay. Independent titration results obtained from two assay methods for a given dilution of virus demonstrated a strong correlation (r2=0.99). Foci of virus infected cells as revealed by the enzyme reaction could be counted either 4 days post-infection (p.i.) under low magnification (40X) microscopy, or 6 days p.i. by naked eye observation. Larger size of cell cuture plate, virus adsorption at 35 degrees C, and 10% FBS in diluent appeared to be better conditions for the assay. Immunofocus assay will be an effective and dependable titration method for varicella-zoster virus and its live vaccine in place of the standard plaque assay in respect to accuracy, costs, and experimental convenience.

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.

One hundred patients of osmidrosis were treated by surgical procedure at the Department of Dermatology, Wonkwang University Hospital. The methods of operative treatment were elliptical excision for 37(74), bipedicle incision with apocrine glancl undercutting for 14(28), and single incision wit.h apocrine gland undercutt,ing for 49 (98). The results were summarized as follows : 1. Of the 74 axillae treated by elliptical excision, one occurred recurrence, and 1.7 showed complication, hematoma in 6, infection and delayed union in 4, each necrosis and severe scar in one each, 2. Of the 28 axillae treated by bipedicle incision with apocrine gland undercutting, 6 showed complication; hematoma in 4, infection and delayed union in one each 3. Of t..he 98 axillae treated by single incision with apocrine gland undercutting, 5 showed complication, hematoma in 3, infection and delayed union in one each In conclusion, single incision with apocrine gland undercutting was found to be more excellent compared with the other surgical methods.

T-cell lymphomas primarily involving subcutaneous tissue and minicking panniculitis have rarely been described. In addition, some cases may have been orviously reported as malignant histiocytosis. Some of the affected patients have developed a hemohagocytic syndrome. A 44-year-old wornan showed multiple, recurrent, ill-defined, sarble sized, erythematous, tender subcutnaeous nodules on the trunk and extremities. Histopathological findings levealed the infiltration of hyperchrorriatiatypical large lymphocytes and nurnerous beanbag-like cells in the subcutaneous fat. The infitrted cells were positively stained with Leucocyte common antigen, UCHL-1 antigen, Lysozyme, that ot with CD20. Bone marrow biopsy showed mild erythreid hyperplasia and erythorophagocytic. hitiocytes. These histopathological features were consistent with cutnaeous T cell lymphoma involvnig the subcutaneous tissue.

Amniotic fluid embolism (AFE) is a rare but potentially fatal complication that occurs acutely during pregnancy or within 12 h of delivery. The management of AFE focuses initially on supportive measures for cardiopulmonary stabilization. Extracorporeal membrane oxygenation should be considered in patients who are unresponsive to medical treatment in order to prevent additional hypoxia and subsequent organ failure. We present a 41-year-old woman with clinical AFE who developed acute respiratory distress syndrome and was treated successfully with extracorporeal membrane oxygenation.

The authors dissected and examined a horseshoe kidney from the cadaver of a 54-year-old Korean female. The results were as follows. Other congenital anomalies or complications were not found, and no renal stones showed on plain radiography of the horseshoe kidney. The horseshoe kidney was located in the area between the 12 th thoracic vertebra and the 4th lumbar vertebra, with the superior extremity of the left kidney 10mm more inferior than that of the right. The isthmus connecting the bilateral kidneys was located at the level of the 3rd lumbar vertebra. The size of the kidney was 102mm × 52mm × 44mm (right) and 108mm × 62mm × 34mm (left), and the superoinferior and anteroposterior lengths of isthmus were 22mm and 10mm, respectively. The abdominal aorta and inferior vena cava passed posteriorly to the isthmus, with the inferior mesenteric artery and lumbar splanchnic nerve passing anteriorly. Some grooves were found on the anterior surface of the bilateral kidney. The hilum of the right kidney faced the anteromedial direction and that of the left kidney faced the anterolateral direction. At the hilar plane, the right renal arteries and veins passed anteriorly and posteriorly to the renal pelvis ; the left renal arteries passed posteriorly to the renal pelvis, with the left renal veins passing anteriorly and posteriorly. Three branches of the right renal arteries passed renal hilum, while two branches did not, and two branches of the left renal arteries passed renal hilum, while six branches did not. The two arteries arising from the aortic bifurcation were distributed to the isthmus. The number of renal veins passing the renal hilum were three in the right, and two in the left. The right and left ovarian veins drained to the renal veins. There were 12 minor calyces distributed normally in the right kidney, 13 minor calyces distributed radially in the left kidney, and 3 minor calyces in the isthmus, composed of parenchyme. The left portion of the horseshoe kidney was concluded to have developed poorly, on the basis of incomplete ascension and abnormal rotation during development, the imperfect configuration of the renal shape, and the abnormal distribution of the renal vessels and renal calyces.

Pure, nongestational ovarian choriocarcinomas is extremely rare. Most ovarian choriocarcinoma are combined with other malignant germ cell tumors or can arise as a metastaais from a primnry gestational choriocarcinoma. We experienced a case of primary ovarian choriocarcinoma that probably was associated with a past history of the mixture of germ cell tumor and present it with a review of literature.
