Krukenberg tumor, which can account for 30-40% of metastatic cancers to the ovaries, arises in the ovarian stroma and is usually metastatic from the gastrointestinal tract, especially from the stomach. The pathognomonic feature is the presence of signet ring cells, which may be arranged in acini or appear as individual cells. We experienced a Krukenberg tumor which was bilateral and associated with left ovarian dermoid cyst. This patient was treated for a primary gastric carcinoma(Stage II) about 3 years ago. After bilateral salpingoophorectomy, she received adjuvant chemotherapy. But, she died about fow months after operation.

BACKGROUND: B cell subset has been divided into B-1 cells and B-2 cells. B-1 cells are found most prominently in the peritoneal cavity, as well as constituting a small proportion of splenic B cells and they are larger and less dense than B-2 cells in morphology. This study was designed to compare the differences in their proliferation and differentiation between B-1 and B-2 cell. METHODS: We obtained sorted B-1 cells from peritoneal fluid and B-2 cells from spleens of mice. Secreted IgM was measured by enzyme-linked immunosorbent assay. Entering of S phase in response to LPS-stimuli was measured by proliferative assay. Cell cycle analysis by propidium iodide was performed. p21 expression was assessed by real time PCR. RESULTS: Cell proliferation and cell cycle progression in B-1 and B-2 cells, which did not occur in the absence of LPS, required LPS stimulation. After LPS stimulation, B-1 and B-2 cells were shifted to S and G2/M phases. p21 expression by resting B-1 cells was higher than that of resting B-2 cells. CONCLUSION: B-1 cells differ from conventional B-2 cells in proliferation, differentiation and cell cycle.

Zenker diverticulum is rare and symptoms of diverticulum are atypical. This is most commonly seen at the Killian's triangle. This is caused by altered motility, which results in abnormal intraluminal pressure and the pushing of the mucosa through weakness of the wall. Treatment is surgical via an endoscopic or external approach. Previous external approaches are associated with high com-plication rates and morbidity. We report a new external surgical approach using the gastrointestinal autostapler (GIA) instrument.

OBJECTIVE: To evaluate the morphometry of the anterior thalamoperforating arteries (ATPA). METHODS: A microanatomical study was performed in 79 specimens from 42 formalin-fixed adult cadaver brains. The origins of the ATPAs were divided into anterior, middle, and posterior segments according to the crowding pattern. The morphometry of the ATPAs, including the premammillary artery (PMA), were examined under a surgical microscope. RESULTS: The anterior and middle segments of the ATPAs arose at mean intervals of 1.75+/-1.62 mm and 5.86+/-2.05 mm from the internal carotid artery (ICA), and the interval between these segments was a mean of 3.17+/-1.64 mm. The posterior segment arose at a mean interval of 2.43+/-1.46 mm from the posterior cerebral artery (PCA), and the interval between the middle and posterior segments was a mean of 3.45+/-1.39 mm. The mean numbers of perforators were 2.66+/-1.19, 3.03+/-1.84, and 1.67+/-0.98 in the anterior, middle, and posterior segments, respectively. The PMA originated from the middle segment in 66% of cases. A perforator-free zone was located >2 mm from the ICA in 30.4% and >2 mm from the PCA in 67.1% of cases. CONCLUSION: Most perforators arose from the anterior and middle segments, within the anterior two-thirds of the posterior communicating artery (PCoA). The safest perforator-free zone was located closest to the PCA. These anatomical findings may be helpful to verify safety when treating lesions around the PCoA and in the interpeduncular fossa.

PURPOSE: The aim of this study is to evaluate the incidence of hyperkalemia and the contributing factors of nonoliguric hyperkalemia in low birth weight infants within 48 hours after birth. METHODS: The incidence of nonoliguric hyperkalemia and difference of clinical features between hyperkalemia (>6.7 mEq/L) and normokalemia (< or =6.7 mEq/L) groups were determined by reviewing medical records of 196 low birth weight infants who were born in Hanyang university hospital between Oct. 2001. and Jul. 2004. We analized the serum level of sodium, potassium, fluid intake, urine output, pH of blood gas and others. RESULTS: Among 196 infants, 17 infants was hyperkalemia developed in 48 hours after birth. In that cases, 10 infants were showed EKG abnormalities, such as ventricular tachycardia. In all cases, birth weight, gestational age, Apgar score, usage of surfactant, urine output, BUN and creatinine were significant. In A group gestational age, urine output, BUN, creatinin were significant, in B group BUN, creatinine were significant, in C group BUN were significant between hyperkalemia and normokalemia. Six infants with hyperkalemia died as a result of hyperkalemia induced cardiac arrhythmia. CONCLUSION: Hyperkalemia frequently occurred extremely premature infants. But hyperkalemia also be developed in low birth weight infants who were not suffered from asphyxia or tissue damage. Serum potassium level should be monitored to avoid life threatening cardiac arrhythmia in low birth weight infant.
