A gastric carcinoma is the commonest malignancy in Korea and the purpose of this study is: a. to predict the prognosis of gastric carcinoma patient preoperatively b. to gastrectomize as minimally as possible to reduce postoperative morbidity c. to compare a radiologic findings with an endoscopic, gross and pathologic features. And two representative cases are presented here and the invasion depth and extent of the gastric carcinoma of the stomach is evaluated and discussed with the review of articles.

Transgenic mice models of Alzheimer's disease were produced by overexpressing APP(amyloid precursor protein) mutant and presenilin mutant genes using the promotors that induced neuronal expression. The neuropathologies, electrophysiological changes and behavioral changes that were demonstrated in these transgenic mice model were amyloid changes, gliotic changes. A-beta increases, deficit in LTP(ling-term potentiation) and behavioral changes. Some or all of the above changes were found in each transgenic mice model. These models generally showed amyloid neuropathology but they usually lacked the neurofibrillary tangles. So, they can be regarded as partial models of Alzheimer's disease. The development of them is undoubtedly the great progress toward future research.

Polyvesicular vitelline tumor of the ovary is an extremely rare variant of yolk sac tumor. We present a case of pure polyvesicular vitelline tumor in a 43-year-old woman. Light microscopy revealed a predominantly polyvesicular pattern embedded in mesoblastic stroma with the cysts showing two type of lining; tall columnar and cuboidal, or mesothelioid cells. The lining atypical cells showed occasional mitoses and intracytoplasmic PAS positive hyaline globules. In some areas, the cystic space contained a large amount of intraluminal hyaline material. Immunohistochemically, alpha- fetoprotein and alpha-1-antitrypsin were detected as a fine granular deposit in the cytoplasm of epithelial cells and hyaline globules. Electron microscopically, marked specialization of the vesicular lining cells suggested a differentiation toward gut structures and mature yolk sac.
