2.Early Treatment of Pseudo-Sac Formation in a Thrombotic Cavity at the Aneurysm Rupture Site.
Journal of Korean Neurosurgical Society 2002;32(3):259-263
The authors report on an endovascular experience using electrically detachable coils and direct clipping for the treatment of ruptured irregularly shaped aneurysms associated with pseudo-sac formation in a thrombotic cavity at the rupture site. These aneurysms might be fragile and associated with a high possibility of repeated rupture, especially, during an endovascular and direct clipping procedures. Between March 1998 and August 2001, 298 aneurysm patients underwent operations at our hospital. Among these patients, 4 patients showed pseudo-sac formation in a thrombotic cavity at the aneurysm rupture site, and were treated using an early endovascular occlusion technique or direct clipping after diagnostic angiography. These aneurysms showed delayed opacification and delayed washout of contrast medium from the irregularly shaped portion of the aneurysm on digital subtraction angiography. Moreover these aneurysms tend to rerupture during GDC embolization because of the fragile pseudoaneurysmal thrombotic cavity at the rupture point. Ruptured aneurysm with pseudo-sac formation in thrombotic cavity display delayed and irregularly shaped filling and retention of contrast medium at the rupture point. Early treatment of these aneurysms prevents rebleeding from the pseudo-sac in the thrombotic cavity at the ruptured site.

3.Treatment and Clinical Results of Coats` Disease.
Journal of the Korean Ophthalmological Society 1999;40(8):2190-2197
To evaluate the clinical courses and the results of treatment of Coats`disease, we retrospectively investigated the medical records of 30 patients (27males,3 females). The age at diagnosis, bilaterality, chief complaints, associated abnormalities, retinal distributions of vascular change and exudate, and methods and results of treatment were reviewed. The average age at diagnosis was 4.6 years (range:1.0~8.2 years) and all cases were unilateral. Exotropia was the most common presenting signs. Following treatment, 60.0%of eyes were clinically worsened in subretinal fluid drainage/vitrectomy group, 6.7% in laser/cryotherapy group,and 28.6%in no treatment group. These results suggest that laser/cryotherapy may treat effectively the early change in Coats`disease, and making a diagnosis and treatment before the development of bullous retinal detachment may be advisable.

Omentum has the characteristic that it readily develops vascular anastomosis with adjacent tissues. It is suitable for eliminating a dead space regardless of the size, shape or site in the treatment of chronic osteomyelitis by use of technique of microvascular anastomoses. We report a case of chronic osteomyelitis treated by transplantation of autogenous omentum with microvascular anastomsis.

PURPOSE: The current work is aimed at illustrating the feasibility and assessing the efficacy of laparoscopic surgery in the treatment of gastric and duodenal diseases. METHODS: 27 patients who suffered from various gastroduodenal diseases were operated on between Feb. 1996 and July 1997. Operating times, procedures associated with pathologic diagnosis, bleeding during operation, mean starting times of oral intake, postoperative hospital stays, and complications were examined using the operating records and the medical charts. RESULTS: The procedures and the associated pathologic conditions were a feeding jejunostomy (gastric cancer peritonei), 12 wedge resections (1 duodenal diverticulum, 1 Brunner's gland hyperplasia, 2 gastric polyps, 6 gastrointestinal stromal tumors, and 2 early gastric carcinomas, 3 gastrojejunostomies (unresectable gastric cancers), 10 subtotal gastrectomies (9 complicated peptic ulcers and early gastric cancer), and a radical (D1 alpha) subtotal gastrectomy. The average operating times were 85 minutes in the feeding jejunostomy, 132 minutes in the wedge resections, 95 minutes in the gastro jejunostomies, 208 minutes in the subtotal gastrectomies (Billroth-I: 160 min; Billroth-II: 262 min.), and 300 minutes in the radical operation. The mean intraoperative bleeding was 80-800 cc. The mean start ing time of solid oral intake and postopeative hospital stay were shorter than in open surgery (oral intake: 1-5 day; hospital stay: 6-9 days). There were six postoperative complications. One patient died due to a cerebral infarction during the operation. one wound infection, one stump leakage, one pulmonary edema, and two cases of postoperative bleeding occurred, but they were treated conventionally without reoperation. CONCLUSION: Minimally invasive surgery appears to be an invaluable tool for treating gastroduodenal diseases. Furthermore, it is a valid option in experienced hands and in selected cases of gastric cancer, allowing patients to benefit from a less cumbersome hospital stay and from more satisfaction.

OBJECTIVE: Epigallocatethin gallate(EGCG) is a major green tea polyphenol and is known to have potent antioxidative and antiproliferative actions. This study is performed to investigate the antioxidative effect of EGCG on the various oxidative insults in mouse cerebral cortical cell cultures. METHODS: Mixed cortical cell cultures containing both neuron and glia prepared by plating fetal mice cortical cells on to an established glia of 24 well vessels. At 13-15 days in vitro, oxidative neuronal deaths were induced by the addition of oxidants into the cortical cultures. Iron ion(FeCl2), copper ion(CuCl2), sodium nitroprusside(SNP) and buthionine sulfoximine(BSO, a glutathione depletor) were used as oxidants. Cell death was assessed by LDH assay after microscopic examination. RESULTS: All four oxidants induced neuronal cell death associated with cell body swelling, which was markedly inhibited by Trolox(100muM), a vitamin E analog. EGCG(1-10muM) markedly inhibited the neuronal cell death induced by 20muM CuCl2, 1muM SNP, or 1mM BSO. Unexpectedly the neuronal cell death induced by 20muM FeCl2 was augmented by treatment with 1 or 3muM EGCG. EGCG itself induced concentration- and exposure time-dependent cell death at more than 30muM concentrations. EGCG(30, 100muM) injured not only neuronal cells but glial cells after 48 hour exposure. The EGCG-induced cytotoxicity was partially inhibited by protein synthesis inhibitors, cycloheximide(0.1 or 1mug/ml) and emetine (1mug/ml) or high potassium media(10 or 25mM) but was not affected by Trolox. CONCLUSION: These results suggest that the dual antioxidative-cytotoxic actions of EGCG are concentration-dependent and that the antioxidative aciton depends on the kind of oxidative insults, and that the EGCG-induced cytotoxicity be relevant to protein synthesis and/or membrane depolarization.
