Analyses were done on one hudred and twenty caaes of bleeding gastric ulcers diagnosed by emergency endoscopy for the past five years. The reaults are as the following: Much more cases were found in male than female and the most prevalent age group was 6th decade. The body of stomach along the lesser curvature was the most common bleeding site. No age related difference was noted in bleeding sites. Most common type of ulcer was in the round and shallow form. Five of six cases with exposed vessels showed atrophic changes in surrounding mucosa. Among the probable precipitating factors, analgesica, alcohols and certicosteroids were found in such order,

Normal human B cells produce autocrine growth factor in response to Staphylococcus aureus Cowan I strain (SAC). However, the functional role and molecular nature of the B cell derived-B cell growth factor (B-BCGF) are largely unknown. We have tried to investigate the nature of B-BCGF using mAb for several years. We report here that B- BCGF is capable of binding to hemoglobin (Hb). The concentrated culture supernatant from tonsillar B cells stimulated with SAC for 24 h was loaded into the fast protein liquid chromatography and ion-exchange chromatography. The peak with BCGF activity was shown to have a M.W. of 16-18 Kda in polyacrylamide gel electrophoresis followed by silver stain. Amino acid sequence of the fraction was found to identical to human hemoglobin (Hb) by more than 85%. However, Hb itself had no BCGF activity. The presence of Hb in culture supernatant was due to the contamination of SRBC during B cell purification. SRSC were completely removed from B cells by percoll-gradient centrifugation and B cells were stimulated with SAC and exogenous Hb was added to the cultures. The Hb fraction from FPLC again showed a BCGF activity. These data strongly suggested that BCGF binds to Hb. We confirmed this in dot blot as well as Western blot. The M.W of Hb-binding BCGF was 20 Kda. This information may provide a rapid progress in research of BCGF.

Recurrent infantile digital fibroma is a peculiar fibrous tumiir that may be single or multiple on fingers and toes of infants and children. We report a 5-year-old gril with recurrent infantile digital fiber oma which was recurrent on the left 5th toe. The lesion had noted at the age of 6 months. and was excised surgically when the child was 3 year old. 2 years after operation, the lesion was recurred in operation site. Microscopically, nodular fibrous mass is attached to flattened,pidermis. The underlying nodule is composed of proliferating fibroblasts surrounded by derse collagenous tissue. We could find eosinophilic inclusion bodies in the cytoplasm of fibro ilast. It was stained pink with H&E, bright red with Massons trichrome and purple with PTAH.

Pseudo-Bartter syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patient with clinically proved pseudo-Bartter syndrome. The patient was a 37-year-old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. Tl-weighted MRI revealed indistinct corticomedullary differentiation.

We reviewed radiographs of 11 patients with 17 total knee replacement arthroplasty(TKRA) cases. These patients had a residual flexion contracture over 20 degree after TKRA that corrected spontaneously during follow-up. The mean age of patients was 46.5 years(range, from twenty nine to sixty six). Seven patients were bilateral cases and all knees were cases of rheumatoid arthritis. The mean preoperative flex- ion contracture was 53.8 and immediately postoperative contracture was 23.5. The remaining flexion contracture after TKRA was completely corrected during follow-up period in all cases. We measured the distance from upper margin of tibial components to a certain point on the fibula. This point is on a line perpendicular to long axis of the tibia, drawn from a certain point on the fibula. This dis- tance was measured on postoperative radiographs and radiographs with improved flexion contracture, and the differences calculated. There was no significant difference between the two distances. Although the number of cases are small, we conclude that flexion contracture might be corrected to the extent of 20-30 degree by soft tissue stretching rather than bone subsidence.

PURPOSE: To evaluate the radiologic characteristics of axillary lymph nodes which are found on mediolateral oblique(MLO) view of mammography and to assess their clinical significance. MATERIALS AND METHODS: We retrospectively evaluated 119 cases axillary lymph nodes on MLO view of 410 cases of mammography in 205 patients regarding the size, bilaterality, number, grade of density, presence of central lucency, calcification of lymph nodes and presence of associated parenchymal pathologic lesions in breast. RESULTS: Axillary lymph nodes on MLO view were demonstrated in 119 (29%) among 410 cases. Axillary lymph nodes(112 cases) in cases without breast parenchymal lesions or with benign breast lesions showed; unilaterality in 68 cases(61%), smaller than 1.5cm in 100 cases(89%), lower density than breast parenchyma in 99 cases(88%), presence of central lucency in 99 cases(88%) and calcification in 3 cases(2.7%). Axillary lymph nodes(7 cases)in cases with breast cancer showed small size of less than 1.5cm in 4 cases(57%), absence of central lucency in 7 cases(100%) and iso-to higher density than breast parenchyma in 7 c&ses(100%). CONCLUSION: Axillary lymph nodes noted on MLO view of mammography, more than 1.5cm in diameter, absence of central lucency and iso to higher density than breast parenchyma could be suggested as clinically significant.

Adrenal cyst is a rare pathologic lesion in all patients which can pose difficult problems in terms of diagnosis and treatment. Most are small and found incidentally on autopsy. We report one case of a large adrenal cyst in a 54-year- old female with review of the literature.
