We examined the expressions of CD44 splice variants (v4/5, v6), alpha-smooth muscle actin, nm23 to evaluate their roles as prognostic factors in 70 cases of uterine cervical carcinoma (stage IB to IIB) who were surgically treated from January 1989 to June 1990 with a clinical follow-up of a minimum of 5 years. The expression was examined by an immunohistochemical method using archival formalin fixed paraffin embedded tissue. In the 70 cases, 61 cases were squamous cell carcinoma and 9 cases were adenocarcinoma. CD44v4/5, CD44v6, alpha-smooth muscle actin, and nm23 were detected in 41.4%, 70%, 100%, and 74.3% of tumor samples, respectively. CD44 splice variants and nm23 showed membrane and cytoplasmic staining of tumor cells, respectively. The expression of alpha-smooth muscle actin showed cytoplasmic staining confined to stromal cells and was classified into three grades by the extent in stromal cells: with less than 10% of stromal cells; 32.9%, 10-50% of stromal cells; 40.0%, more than 50%; 27.1%. These expressions were not correlated with histologic types, lymph node involvement, recurrence, and grades of tumor infiltrating lymphocyte (TIL). But CD44v4/5 had significantly inverse correlation with TIL (p=0.049). The expression of CD44v4/5 was significantly correlated with that of CD44v6 (p=0.05), and that of alpha-smooth muscle actin was inversely correlated with that of nm23 (p=0.049). In conclusion, in FIGO IB-IIB uterine cervical carcinoma CD44 variants, nm23, and SMA show high prevalence, however, with little prognostic significance assessed by recurrence and lymph node metastasis.

In order to evaluate the possible roles of secretory proteases in the pathogenesis of amoebic keratitis, we purified and characterized a serine protease secreted by Acanthamoeba lugdunensis KA/E2, isolated from a Korean keratitis patient. The ammonium sulfate-precipitated culture supernatant of the isolate was purified by sequential chromatography on CM-Sepharose, Sephacryl S-200, and mono Q-anion exchange column. The purified 33 kDa protease had a pH optimum of 8.5 and a temperature optimum of 55 degrees C. Phenylmethylsulfonylfluoride and 4- (2- Aminoethyl) -benzenesulfonyl-fluoride, both serine protease specific inhibitors, inhibited almost completely the activity of the 33 kDa protease whereas other classes of inhibitors did not affect its activity. The 33 kDa enzyme degraded various extracellular matrix proteins and serum proteins. Our results strongly suggest that the 33 kDa serine protease secreted from this keratopathogenic Acanthamoeba play important roles in the pathogenesis of amoebic keratitis, such as in corneal tissue invasion, immune evasion and nutrient uptake.

5.A Case of Low-Grade Endometrial Stromal Sarcoma of the Uterus (So-Called "Endolymphatic Stromal Myosis").

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

The venous malformation in head and neck is a developmental vascular disease which arises from the arrest in the certain stage of vascular embryogenesis. However, the lesion extends along the fascia and has a tendancy to recur after incomplete therapy. Retrospectively, the authors reviewed radiologic studies of 20 patients diagnosed as venous malformation during the last 5 years. The diagnosis was verified by histopathology (5 patients) and direct puncture angiography (15 patients). The radiologic studies included. CT with intravenous contrast injection (20 patients), RI angiography with 99m Tc-pyrophosphate (6 patients), and direct puncture angiography (15 patients). Multiplicity of venous malformation was noted in 9 patients. On CT scan, the lesions had lobulated irregular shape, with heterogeneous appearance, showed delayed enhancing characteristics, and had the phleboliths(21 lesions). The venous malformations were located at the masticator space (including masseter muscle) (n=12), retrobulbar space(n=6), submandibular space(n=4), paravertebral space(n=3) and so on. In two cases, the lesions were very extensive involving entire neck and parapharynx. On RI angiography using 99mTc-pyrophosphate, all of the lesions showed persistent and delayed uptake. With direct punture angiography the lesions could be classified as acinar pattern (n=17) and mixed pattern (acinar and saccular) (n=2). Venous connections were noted in 10 lesions. In conclusion, if a soft tissue mass on head and neck shows a heterogeneous attenuation density with or without calcified phlebolith on CT scan, RI angiography is recommended as a next diagnostic study. If it shows delayed persistent uptake, venous malformation can be suspected. Finally direct puncture angiography can verify the nature and extent of the lesions.

PURPOSE: To determine the therapeutic effect between Ellman Surgitron(R) thermolysis and Argon laser thermoablation in patients with trichiais. METHODS: Thirty-one patients (46 eyes) were analyzed. We performed Argon laser thermoablation in 23 patients (35 eyes) and Ellman Surgitron(R) thermolysis in 8 patients (11 eyes). Mean age was 54. Mean follow-up period was 11 months in Ellman Surgitron(R) group, 46 months in Argon laser group. RESULTS: In Argon laser group, 17 cases of 13 patients were performed successfully in first procedure (48.6%), and cumulative success rate was 68.6% after second procedure. Eleven eyes of 6 patients (31.4%) were performed more than three times or needed to surgical intervention. On the other hand, in Ellman Surgitron(R) group, 7 cases of 5 patients (63.6%) were successfully performed in first procedure, and second procedure makes all patients allowed to be successful in treatment of trichiasis. In all two groups, complications such as lid defect, granulation tissue formation, continuous pain and erythematous skin lesions were not found. CONCLUSIONS: The success rate of Ellman Surgitron(R) thermolysis is higher than Argon laser thermoablation, and all patients in Ellman Surgitron(R) group were treated within second procedure without recurrence. The above results suggest that Ellman Surgitron(R) thermolysis is one of the good methods to treat trichiasis.
