PURPOSE: To identify the four layers based on intranodular vascular nature visible in multiphase incremental bolus dynamic CT and to determine any differential points according to various factors of liver abscess with this vascular nature or not. MATERIALS AND METHODS: We categonized 29 cases of confirmed liver abscess into three different groups according to presence of four layers visible in early phase(arterial phase) of CT. Three groups were compared in regard to the results of antiamebic antibody test and bacteriologic study and presense of cholangitic abscess and internal septation. RESULTS: We could separate four layers, innermost hypodense central cavitary lesion, hyperdense granular tissue, hypodense abscess wall and outermost hyperdense compensatory hypervascular zone in 18 cases(62%), only two layers, cavity and wall in six cases(21%), and characteristically we could find three layers without innermost cavitary lesion in five cases(17%). But we couldn't find significant correlations between various clinical factors of liver abscess and our vascular groups. CONCLUSION: Our method of CT could represent four layers based on vascularity in 62% of cases. And also could find the unusual inflammatory mass containing three layer which must be differentiated from other malignant solid mass. But we couldn't find differential point between various clinical factor of liver abscess and imaging diagnosis. We think that with the improvement of hardware such as spiral CT, identification of four layers will be earier and will be very helpful in early detection and proper treatment planning of liver abscess.

PURPOSE: DNA mismatch repair gene is responsible for hereditary nonpolyposis colorectal cancer. But it is not well known its role in sporadic colorectal cancer patients. We analysed normal hMSH2, hMLH1 protein expression in colorectal adenocarcinoma tissues and corresponding normal tissues to find out the role of mismatch repair gene in sporadic colorectal cancer by Western blotting. METHODS: Normal hMSH2 and hMLH1 protein expression was studied on 25 colorectal cancer and corresponding normal tissue by Western blot with hMSH2 and hMLH1 monoclonal antibody. Normal protein band was expressed on 100 kD in hMSH2 and 87 kD in hMLH1. SW480 and LoVo cell line was used as positive and negative control for hMSH2 and LoVo and SW480 as positive and negative for hMLH1. And we analysed the relation between the hMSH2, hMLH1 protein expression and clinicopathological parameters. RESULTS: It was 2 cases (8%) that both hMSH2 and hMLH1 protein expression was not observed. Three cases (12%) were negative for hMSH2 and 2 cases (8%) for hMLH1. One or both hMSH2, hMLH1 protein expression was not observed in 7 cases (28%) in total. There was no correlation for proximal occurrence (25% vs 35%), young age (37.5% vs 23.5%) and lymph node metastasis (50% vs 47%). But poorly and mucinous differentiation was regarded as having relation with negative expression of hMSH2 and hMLH1 (50% vs 17.6%) but not significant statistically. CONCLUSION: Sporadic colorectal cancer with negative expression of normal hMSH2 and hMLH1 protein showed no relation to younger age, proximal site preference and lymph node metastasis. But it was suggested that mismatch repair gene protein was involved in cancer cell differentiation in sporadic colorectal cancer.

Epidermal cyst in the fibroadenoma of the breast is very rare. A 29-year-old woman presented with a lump in the upper outer quadrant of the right breast. Clinically it was a fibroadenoma and the excisional specimen showed an encapsulated, firm lobulated lesion with a cystic area on cut surface. The cystic area showed squamous metaplasia of the ductal epithelium and keratinous cyst formation in the fibroadenoma. We report this unusual case with review of literatures.

One hundred fifty-seven patients wha underwent radical hysterectomy and pelvic lymphadenectomy for FIGO stage IB and IIA carcinoma of the cervix between February l975 and May 1987 were retros-pectively analysed to identify specific risk factors associsted with treatment failures. Prognostic factors inciuded clinical stage, histologic cell type, degree of differentiation, size of primary tumor, depth of stromal invasian, lymph-vaseular space invasion, and lymph node metastasis. Treatment results were evaluated according to the recurrence rate and 2-year absolute recurrence-free survival(NED) rate by the prognostie faetors and treatment modalities. Patients with lymph node me tases had a significantly higher incidence of bulky primary(-> 4cm), depth of stromal invasion(> 60% thickness), and lymph-vascular invasion(P<0.005). There was significant difference in the recurrence rate and 2-year, NED rate between cervical carcinoma stage IB and I1A(P <0.005). The pat,ients who had bulky primary tum~or(>4cm) and/or depth of stromal invasion (>60% thickness) had a higher recurrence and lower 2-year NKD rate(P<0.025, P<0.005), Unfortunately, it was not possible to demonstrate that these detrimentel effects could be overeorne by postoperetive radiation. When adjoined for these risk group, traditionally reported poor prognostic factors such as nodal metatasis, cell type and differentiation, lyrnphi-vascular mvasion assume less importance in our studies. In this study, prognosis is most inf1ueneed by clinical stage, depth of stromal invasion, and size of primary tumor,

A survey was performed in order to determine the infection status of the metacercariae of heterophyid fluke in two goby species, Boleophthalmus pectinirostris and Scartelaos sp., collected from Gangjin-gun, and Shinangun, Sooncheon-shi, Jeollanam-do, Republic of Korea. A total of three metacercariae of Heterophyopsis continua was found in only one B. pectinirostris (10.0%) from Gangjin-gun. Heterophyes nocens metacercariae were detected in 24 B. pectinirostris (96.0%) and 14 Scartelaos sp. (63.6%) from Shinan-gun. Heterophyopsis continua metacercariae were found in 11 B. pectinirostris (44.0%) and 21 Scartelaos sp. (95.5%) from Shinan-gun. Stictodora fuscata metacercariae were detected in 18 B. pectinirostris (72.0%) from Shinan-gun. No metacercariae were detected in 20 B. pectinirostris from Sooncheon-shi. From the above results, this study is the first to prove that B. pectinirostris and Scartelaos sp. serve as the second intermediate hosts of some heterophyid flukes in Korea.
