A few delayed epistaxis was reported, and it is an unusual complication of closed head injury. We experienced 2 cases of delayed epistaxis and monoocular blindness by cavernous vascular lesions(traumatic aneurysm and C. C. F.). We confirmed the vascular lesions by carotid angiography and Brain C. T. They were treated by carotid ligation and carotid ligation with embolization, and we mer with good results. We present 2 cases of the delayed epistaxis complicated by traumatic lesions of cavernous internal carotid artery, and also the literatures were reviewed.

Hypereosinophilic syndrome is characterized by prolonged eosinophilia of blood and tissue without an identifiable underlying cause and multiorgan system dysfunction by eosinophil-related tissue damage to variable organs: liver, heart, lung, kidney, gastrointestinal tract, skin, nerve. Some case of hypereosinophilic syndrome with hepatic and gastrointestinal involvement have been reported, but not much. We are reporting a case of hypereosinophilic syndrome with hepatic and gastrointestinal involvement in 56-year-old man who presented general weakness and epigastric discomfort. In abdominal US, CT and MRI, intrahepatic multifocal ill-defined lesions were detected. The patient was treated with prednisolone for 16 weeks and recovered from eosinophilia and gastric involvement. A gastric biopsy was taken to confirm recovery. Also, the ill-defined lesions in US and CT disappeared after treatment.

PURPOSE: For the research of Boron Neutron Capture Therapy (BNCT), fast neutrons generated from the MC-50 cyclotron with maximum energy of 34.4 MeV in Korea Cancer Center Hospital were moderated by 70 cm paraffin and then the dose characteristics were investigated. Using these results, we hope to establish the protocol about dose measurement of epi-thermal neutron, to make a basis of dose characteristic of epi-thermal neutron emitted from nuclear reactor, and to find feasibility about accelerator-based BNCT. METHOD AND MATERIALS: For measuring the absorbed dose and dose distribution of fast neutron beams, we used Unidos 10005 (PTW, Germany) electrometer and IC-17 (Far West, USA), IC-18, EIC-1 ion chambers manufactured by A-150 plastic and used IC-17M ion chamber manufactured by magnesium for gamma dose. There chambers were flushed with tissue equivalent gas and argon gas and then the flow rate was 5 cc per minute. Using Monte Carlo N-Particle (MCNP) code, transport program in mixed field with neutron, photon, electron, two dimensional dose and energy fluence distribution was calculated and there results were compared with measured results. RESULTS: The absorbed dose of fast neutron beams was 6.47x10-3 cGy per 1 MU at the 4 cm depth of the water phantom, which is assumed to be effective depth for BNCT. The magnitude of gamma contamination intermingled with fast neutron beams was 65.2+/-0.9% at the same depth. In the dose distribution according to the depth of water, the neutron dose decreased linearly and the gamma dose decreased exponentially as the depth was deepened. The factor expressed energy level, D20/D10, of the total dose was 0.718. CONCLUSION: Through the direct measurement using the two ion chambers, which is made different wall materials, and computer calculation of isodose distribution using MCNP simulation method, we have found the dose characteristics of low fluence fast neutron beams. If the power supply and the target material, which generate high voltage and current, will be developed and gamma contamination was reduced by lead or bismuth, we think, it may be possible to accelerator-based BNCT.
