A case of testicular embryonal carcinoma developed in s cryptorchid testis is presented with a review of the literature. According to Campbell's series, the incidence of malignant cryptorchid testis was 11.6%. and his statistical evaluation was similar to Gilbert and Hamilton's series of 7,000 cases of testicular neoplasms where 840 tumors were developed in undescended testes(12%). Both authors agree that the chance of neoplastic development in a cryptorchid testis is approximately 48 times greater then that developing in a normally descended testis. Several cases of testicular tumor were reported sporadically in Korea, but malignant tumors in cryptorchism were rarely seen in the literatures Only two cases of malignant cryptorchid testis were already reported in Korea.

Dupuytren's contracture is characterized by a proliferative fibroplasia and contracture of the palmar fascia with resultant deformity of hand and finger. It is most common in those of Scandinavian and Celtic origin but it is very rare in the orientals. We experienced 30 hands of 21 patients from January 1985 to December 1995 in Soonchunhyang University Hospital. Among 21 patients, operative treatment was done in 28 hands of 19 patients. Partial fasciectomy was done in 24 hands and complete fasciectomy was done in 4 hands. The longitudinal straight skin incision was done in 14 cases and the transverse or Zig-Zag incision was done in 12 cases. Average follow-up period was 24 months. The results of the operative treatment were classified by Honner's classification. Excellent result was obtained in 16 cases (57%), good in 8 (29%), fair in 3 (11%), poor in 1 (3%). The complications were 5 cases as follows; recurrence 2, skin defect 1, hypoesthesia 2. In conclusion, partial fasciectomy utilizing longitudinal straight incisions overlying diseased area is suggested as one of the good method for the treatment of Dupuytren s contracture.

PURPOSE: We determined the effect of tyrosine kinase inhibitor(TKI), ZM260603 on the growth of prostate cancer cell lines. MATERIALS AND METHODS: Using the synthetic TKI, ZM260603, cytotoxicity test and cell cycle analysis were performed on LNCaP, DU-145 and PC3 prostate cancer cell lines. The bcl-2 and bax protein expressions were observed in PC3 prostate cancer cell line by western blotting. The inhibitory effect of TKI was determined under the presence or absence of dehydrotestosterone, in androgen-dependent LNCaP prostate cancer cell line. RESULTS: The synthetic TKI, ZM260603 showed definite cytotoxicity on all prostate cancer cell lines studied regardless of androgen-dependency. The IC50 were 0.35+/-0.08microM, 0.12+/-0.06microM and 0.21+/-0.09microM for LnCaP, DU-145 and PC-3 cell lines, respectively. The G0/G1 phase arrests were observed commonly in all of these cell lines by flowcytometric analysis. Decrement in bcl-2 expression and increment of bax protein expression in the PC-3 cell line was observed by western blotting. The IC50 of hormone-dependent LNCaP prostate cancer cell line on TKI was increased about four folds by the addition of dihydrotestosterone. CONCLUSIONS: Our results suggest that the changes in the expression of bcl-2 and bax proteins are related with inhibitory process of the synthetic TKI, ZM260,603 on the growth of prostate cancer cell lines. Androgen seems to act as compromising or weakening the effects of TKI in androgen-dependent prostate cancer cell line, although the exact relationships between androgen-dependency and bcl-2 expression are unclear.

Multiple meningiomas are a seldom encountered neoplasm. Most authors report an incidence ranging from 1 to 3% of all meningioma prior to the introduction of computerized tomography(CT). The routine use of CT has resolved diagnostic problems involved with multiple meningiomas and the incidence was 8% since the introduction of CT scan. In fact, it may be difficult to differentiate "true multiple meningioma" from simple recurrences or the special variant(forme fruste) of Von Recklinghausen's disease, and the pathogenetic factors related to true multiple meningioma is unknown, but various theroies of the etiology are explored by literature reports. We report the rare case of multiple meningiomas which diagnosed by CT scan and confirmed by operation.

The role of cerebral revascularization in the treatment of ischemic stroke has been incompletely investigated. Ten patients with middle cerebral artery occlusion or stenosis and four patients with internal carotic artery occlusion or stenosis underwent superficial temporal artery-middle cerebral artery(STA-MCA) bypass surgery in the setting of acute neurological deficits, crescendo transient ischemic attacks(TIA'S), or recent completed stroke(CS). Early STA-MCA anastomosis was remarkably helpful in the setting of acute cerebral ischemia and crescendo TIA'S for their symptomatic relief. In addition, low flow revascularization were performed safely and also contributed to stabilization or slight reduction of the neurological deficit enen in CS. However, further controlled randomized studies are indicated.

BACKGROUND: Elastic fibers are a major fibrillar component of the extracellular matrix of several organs, and their presence provides elastic properties to these tissues. Recent molecular biological studies also have revealed that accumulation of elastotic material in the skin reflects enhanced synthesis of not only elastin but also a fibrillin, an integral component of the elastic fibers, and steady-state levels of the elastin mRNA increased in photodamaged skin. Futhermore, a variety of cytokines, growth factors, and hormones have been shown to modulate elastin gene expression including transforming growth factor- beta, tumor necrosis factor-a, insulin-like growth factor-I, glucoreorticoids, cyclic AMP, and vitamin D3. Recently, interleukin-1 beta (IL-1 beta) and IL-10 has been shown to up-regulatory function in elastin gene expression. OBJECTIVE: The purpose of this study was to examine the effect of IL-1 beta and IL-10 on elastin gene expression in cultured human fibroblasts. METHODS: Fibroblasts cultures were produced with DMEM medium. Cells were treated with IL-1 p (1U/ml, 10U/ml) and IL-10(0.1ng/ml, 1ng/ml, 10ng/ml) nuclear proteins were extracted. Effect of IL-1 beta and IL-10 on elastin gene expression were measured by Northern blot analysis, chloram- phenicol acetyltransferase(CAT) assay, and laser confocal microscopy. RESULTS: In Northern blot analysis, IL-1 beta and IL-10 showed an up-regulatory effect on elastin mRNA steady-state levels compared with controls incubated without IL-1 p and IL-10. In CAT assay, the percentage of acetylation were increased in cultured fibroblasts. The promoter activities were increased 1.5 and 2.2-fold in IL-1 beta (1U/ml, 10U/ml) and 2.2-fold in IL-10(lng/ml, 10ng/ml) treated fibroblasts compared to control groups. In laser confocal microscopy, the results indicated significant increase in the elastin epitopes associated with the cells in cultured with IL-1 beta and IL-10. CONCLUSION: These results show that IL-1 p and IL-10 increase elastin gene expression on transcriptional and protein levels of cultured fibroblasts. It suggests that they may effect on elastin synthesis by a stage up-regulater in human skin.

Kimura's disease (KD) is a rare, chronic inflammatory disorder, which is characterized by tumor-like masses mainly located in the head and neck region. Extraocular muscle involvement in KD is uncommon. We report a case of KD that involved both the extraocular muscles and buccal area. A 13-year-old male presented to our clinic with a two-year history of exophthalmos of the left eye and facial swelling. Facial CT and MRI showed a 1.5 x 1.5 cm2 soft tissue mass located at the left masticator and buccal area, exophthalmos of the left eye, and diffuse thickening of the left extraocular muscles. We performed a lateral rectus muscle incisional biopsy of the left eye. Oral methylprednisolone therapy was initiated and tapered following the incisional biopsy.
