PURPOSE: The purpose of this study is to evaluate the gadolinium-enhanced MR imaging findings of cerebral venous angiomas, and to compare those findings with those of cerebral angiography. MATERIALS AND METHODS: We reviewed the findings of gadolinium-enhanced MR images of 11 cases with angiographically proved cerebral venous angiomas. We obtained Tl-and T2-weighted images with gadoliniumenhanced Tl-weighted images at a 0.5 T MR imager with a spin-echo technique. We analyzed the location and signal intensity of the lesion, pattern of contrast enhancement, the distribution of draining veins and medullary veins before and after contrast enhancement, and then compared with the findings of cerebral angiography. RESULTS: The characteristic central tubular signal void structure showed low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images in all cases. After gadolinium enhancement, we could find a characteristic enhancement of all medullary and central veins in 7 cases. CONCLUSION: Gadolinium-enhanced MR image was useful in the diagnosis of venous angiomas especially in the detection of medullary veins. The invasive cerebral angiography could be replaced by this technique in this disease.

Subtrochanteric fracture is well known for its difficulty in management, though various devices of rigid fixation have been developed. Each internal fixation device requires a lot of surgical instruments and the surgeon must be skillful in using them. Osteo self-compression plate which was preoperatively bent to fit the contour of the lateral surface of the subtrochanteric region was proved to be technically easy to fix these fractures without causing major complication. Present authors recommend to use this prebent Osteo self-compression device to treat this fracture when the surgical instruments are not fully equipped, and suitable fixation devices are not available, and/or the surgeon has no experience in handling the newly developed surgical instruments for the subtrochanteric fracture.

The ulcerative colitis is a relatively common disease in the European and North American countries aince Dr. Wilks has first reported the cases in 1895, But in Korea, this disease is a rare entity and only a few case have been reported. However, rescently the diagnoetic methods for ulcerative colitis are much developed we have experienced 28 cases of ulcerative colitis which were diagnosed by endoscopy, barium enema exam and biopsy. Therefore a total of 28 patient with ulcerative colitis diagnosed and treated at the department of internal medicine of HYUH from June 1979 to June 1986 was reviewed. We obtained the results as follows; 1) The sex distribution assumed a ratio of 1 to 1.33 with 12 males and 16 females. 2) The age dietribution was relatively even but the majority of cases were between 5th and 6th decade (32.1%), 3) The most prominent clinical symptoms were rectal bleeding, abdominal pain, diarrhea, fever, wight loss and vomiting. 4) Significant laboratory findins were anemia, eleveited ESR, leukocytosis, positive stool OB, electrolyte imbalance and decreased serum albumin level. 5) As to the extent of disease determined by the barium enema examination and endoscopic exam., rectum or rectosigmoid colon is involved in majority of the cases (92.8%). 6) The endoscopic examination was performed in all 28 cases and showed significant findings such as ulceration, hyperemia, mucosal friability, bleeding etcs. 7) The barium enema examination was performed in 19 cases and showed positive findings such as ulceration, luminal narrowing, bowel shortening and rigidity in 17 cases. 8) 21 of 28 patients treated by medical therapy showed relatively improved but 4 of 28 patients was exacerbated or relapsed and one has expired.

Despite the reduced incidence and mortality, gastric cancer remains the second leading cause of cancer death in Korea. Metastatic gastric cancer is regarded as an incurable condition, and chemotherapy is usually accepted as standard palliation. A number of randomized studies were performed comparing supportive care strategies with intravenous chemotherapy. The results demonstrated that systemic treatment can actually improve overall survival and quality of life to a certain extent. However, there is no agreement for standard of treatment in this setting. Recently, a number of newer compounds such as taxanes, topoisomerase I inhibitors and oral fluoropyrimidines have been intensively studied. The surgical resection still remains as the cornerstone of gastric cancer treatment. However, the high rate of recurrence and poor survival after surgery provides a rationale for the early use of adjuvant treatment. A large intergroup study (INT-0116) showed that combined chemoradiation following to gastric resection improves median time to relapse and overall survival. Future advances in the therapy of advanced and resectable gastric cancers may come from the application of new cytotoxic and molecularly targeted agents such as growth factor receptor antagonists and anti-angiogenesis agents.

PURPOSE: To evaluate the expression of the Na(+)-K(+)-2Cl(-)-cotransporter 2 (NKCC2) in the ischemic rat retina. METHODS: Retinal ischemia was induced by pressures 90 to 120 mmHg, above systemic systolic pressure. Immunohistochemistry and western blot analysis were performed. RESULTS: NKCC2 is expressed in the normal retina and its expression is increased by ischemia caused by intraocular pressure elevation. NKCC2 immunoreactivity was observed mainly in axon bundles of ganglion cells and horizontal cell processes in the retina. NKCC2 expression continuously increased with a peak value 3 days (to 415% of normal levels) after ischemic injury, and then gradually decreased to 314% of controls until 2 weeks post injury. The mean density of NKCC2-labeled ganglion cells per mm2 changed from 1,255 +/- 109 in normal retinas to 391 +/- 49 and 185 +/- 37 at 3 days and 2 weeks after ischemia, respectively (p < 0.05), implying cell death of ganglion cells labeled with NKCC2. CONCLUSIONS: Taken together, these results suggest that NKCC2, which is expressed in retinal ganglion and horizontal cells, may contribute to cell death by ischemic injury in the retina, although the molecular mechanisms involved remain to be clarified.
