Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.

Adult Clonorchis sinensis were collected from the biliary passage of nine cases of medico-legal autopsies. The worms were washed repeatedly with tap water and rinsed twice with physiological saline. Incubation took place in Tyrode's medium in order to recover live worms. The number of worms surviving in the medium was determined. The rate of surviving worms showed an unexpectedly high percentage (22.8%) in those cases autopsied 2 days after death. The surviving worm burden dropped sharply to 6.3 and 9.2 percent for those samples taken 5 days after death.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

This investigation were performed in order to study the mechanism of neuronal cell degeneration and mediated gene of retinal cell death in optic nerve transection model. The optic nerve was transected at 5mm posterior from eye ball without affecting the retinal blood supply. Expression of cell deth gene were observed by p53p and Bax immunohistochemistry. The density of ganglion cels was determined by flat-mounted retinas after axotomy. Dying cells contained the pycnotic nuclei at 1 and 2 weeks and approximately 50% of ganglion cells were degenerated within 14 days after axotomy in ganglion cell layer. Bax and p53 were found to be expressed in the ganglion cell layer and inner unclear layer at 7 and 14 days after optic nerve transection. At 14 days, expression of death genes were observed strogly in ganglion cell layer and partially in inner unclear layer. this study suggest that p53p and Bax proteins may mediate ganglion cell degeneration after axotomy.

The purpose of this study was to verify whether small intestinal peristalsis could be observed and quantitatively assessed using pulsed-Doppler ultrasound. Pulsed-Doppler ultrasound was used to evaluate small intestinal peristalsis after a meal in ten normal dogs and ten sedated dogs. The small intestinal peristalses were measured 0, 1, 3, 6, 9, 12, and 24 hours after a 24-hour fast and after feeding. The number of small intestinal peristalsis were 0.133/min, 0.100/min, 0.033/min, 0.167/min, 0.070/min, 0.067/min, and 0.100/min in the fasted dogs, and 1.667/ min, 0.933/min, 1.133/min, 1.234/min, 1.933/min, 1.533/ min, and 0.533/min in fed dogs, respectively. In the dogs sedated with xylazine HCl, the number of small intestinal peristalsis was significantly reduced (p<0.01). However, in the dogs treated with ketamine HCl and acepromazine, the number of small intestinal peristalsis remained unchanged. Therefore, it can be concluded that pulsed-Doppler ultrasound allows graphic visualization of the intestinal movements, which can be subjected to qualitative and quantitative analysis, and may be suitable for a non-invasive study of small intestinal motility.

PURPOSE: To assess the combined effectiveness of angioinfarction and immunotherapy for improving survival in patients with stage IV renal cell carcinoma. MATERIALS AND METHODS:During the past 3 years, 13 patients of stage IV renal cell carcinoma were treated with angioinfarction and immunotherapy. Angioinfarction was performed on these 13 patients using absolute ethanol and occlusive baloon catheter. After angioinfarction, Interferon alpha was used for immunotherapy. For our analysis, 12 control patients of stage IV renal cell carcinoma without treatment were included in the study. Survival has been calculated according to the Kaplan and Meier method. RESULTS: The 1 year survival rate and median survival time in patients treated with angioinfarction and immunotherapy, were 46% and 13 months and in patients without treatment, 16% and 4 months, respectively. CONCLUSION:The combined treatment of angioinfarction and immunotherapy is of considerable value for improving survival in patients with stage IV renal cell carcinoma

Journal of the Korean Ophthalmological Society 1989;30(6):1021-1024
Methanol poisoning is a rare disease but may cause blindness and, in severe cases, results in death. It may develop lesions in optic nerve and retina, which may be accompanied with permanent visual damage. We report a case of Methanol poisoning in a 20 year-old male patient, which is followed by optic atrophy and loss of vision.

PURPOSE: To evaluate efficacy and the safety of percutaneous catheter drainage in patients with pneumothorax that is difficult to treat with closed thoracotomy. MATERIALS AND METHODS: We retrospectively reviewed effectivenss of percutaneous catheter drainage (PCD) in 10 patients with pneumothorax. The catheter was inserted under fluoroscopic guidance. Seven patients had spontaneous pneumothorax caused by tuberculosis (n=4), ruptured bullae (n=2), and histiocytosis-X(n=l). Three patients had iatrogenic pneumothorax caused by trauma (n=l) and surgery(n=2). All procedures were performed by modified Seldinger's method by using 8F-20F catheter. RESULTS: All catheters were inserted successfully. In 9 of 10 patients, the procedure was curative without further therapy. Duration of catheter insertion ranged from 1 day to 26 days. In the remaining 1 patient in whom multiple pneumothorax occurred after operation, catheter insertion was performed twice. CONCLUSION: Percutaneous catheter drainage under fluoroscopic guidance is effective and safe procedure for treatment of pneumothorax in patients with failed closed thoracotomy.
