Gastrofiberscopic findings under direct vision were analysed in 248 patients who were diagnosed as gastric cancer from Feb. 1980 to March 1983 in Department of internal Medicine, Kang Nam Sacred Heart Hospital, Hallym Medical College, Seoul, Korea. (continue...)

Human epithelial cell line immortalized by Ad12-SV40 hybrid virus was transfected with plasmid containing HPV-16 via calcium-phosphate method. Subsequently, 8 clonal cell lines were obtained after G418 selection. Among these clonal cells, clonal cell-4(C-4) and clonal cell-6(G-6) showed increases of tumorigenic cellular properties such as saturation density, soft agar colony formation and cell aggregation. Morphological alteration such as appearane of foci was observed on these two clones after passage 6 and 7(50 to 55 days after transfection). When clonal cells and control cells were treated with MNNG(0.01ug/ml), both C-4 and C-6 showed increases of tumorigenic cellular properties and the level of increase was much more elevated as compared to clonal cells prior to MNNG treatment. Appearance of foci formation was observed in C-4 and C-6 after passage-6. After passage-8, control cells and all clonal cells showed morphological alterations. It seems that treatment of cells containing HPV-16 DNA with MNNG increases tumorigenic properties of the cells and expedite morphological transformations. (continue)

PURPOSE: To evaluate the change of iris-trabecular contact index (ITC index) after cataract surgery in acute angle closure glaucoma. METHODS: Twelve patients (17 eyes) who had a history of acute angle closure glaucoma underwent swept source optical coherence tomography before and after cataract surgery. Correlations between lens vault (LV), ITC index and intraocular pressure (IOP), anterior chamber depth (ACD), anterior chamber volume (ACV), and angle parameters were analyzed before and after cataract surgery. RESULTS: IOP (p = 0.007), ACD (p < 0.001), ACV (p < 0.001), angle parameters (p = 0.001), and ITC index (p = 0.012) were improved after cataract surgery. ITC index decreased from 88.42 ± 23.59% to 48.91 ± 35.13% after cataract surgery (p = 0.012). There was no correlation between LV and ACD (p = 0.075), ACV (p = 0.864), angle parameter (p = 0.112-0.707), or ITC index (p = 0.288) before cataract surgery. The correlations between ITC index and IOP (p = 0.021), ACD (p = 0.002), ACV (p < 0.001), and angle parameter (p = 0.001-0.030) were statistically significant before surgery but not statistically significant (p = 0.223/0.206/0.761/ 0.096-0.819) after surgery. CONCLUSIONS: ITC index significantly improved after cataract surgery, but part of angle closure was not resolved in some cases of acute angle closure glaucoma.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

We presented a case of acute febrile neutrophilic dermatosis (Sweet's syndrome) in 57 years-old female. This case is the 31 st case in the literature and the first case in Korea. Erythematous plaque was presented on the face with tendency of recurrences. Histologically a dense inflammatory cell infiltration composed predominantly of polymorphonuclear neutrophiles, lmphocytes and histiocytes was seen in dermis. Positive laboratory findings were polymorphonuclear leukocytosis and elevated ESR. The symptoms were well centrolled with orally administered preclnisolone.
