PURPOSE: To evaluate the efficacy and safety of extended-field radiation therapy for patients with thoracic superficial esophageal cancer (SEC). MATERIALS AND METHODS: From May 2007 to October 2016, a total of 24 patients with thoracic SEC (T1a and T1b) who underwent definitive radiotherapy and were analyzed retrospectively. The median total radiotherapy dose was 64 Gy (range, 54 to 66 Gy) in conventional fractionation. All 24 patients received radiotherapy to whole thoracic esophagus and 23 patients received elective nodal irradiation. The supraclavicular lymph nodes, the celiac lymph nodes, and both of those nodal areas were included in 11, 3, and 9 patients, respectively. RESULTS: The median follow-up duration was 28.7 months (range 7.9 to 108.0 months). The 3-year overall survival, local control, and progression-free survival rates were 95.2%, 89.7%, and 78.7%, respectively. There were 5 patients (20.8%) with progression of disease, 2 local failures (8.3%) and 3 (12.5%) regional failures. Three patients also experienced distant metastasis and had died of disease progression. There were no treatment-related toxicities of grade 3 or higher. CONCLUSION: Definitive extended-field radiotherapy for thoracic SEC showed durable disease control rates in medically inoperable and endoscopically unfit patients. Even extended-field radiotherapy with elective nodal irradiation was safe without grade 3 or 4 toxicities.

PURPOSE: To evaluate the clinical results of implantation of hydroxyapatite orbital implant in patients with retinoblastoma. METHODS: The medical records of 31 children who had undergone hydroxyapatite implantation after enucleation or secondary hydroxyapatite implantation, for retinoblastoma from April 1994 to January 2006 were reviewed retrospectively. RESULTS: The mean age at the time of operation was 64.1 months (range, 1 to 247 months). The mean follow-up period was 35.3 months (range, 3 to 139 months). The diameter of the orbital implants most used was 20 mm (35.4%, range, 16~21 mm). Tutoplast(R), Vicryl mesh(R), and Neuropatch(R) were used as the wrapping materials for hydroxyapatite orbital implant. Of 31 patients (31 eyes), 8 eyes were found to have complications: 6 eyes showed lower lid sagging (19.4%), 1 eye granulation tissue overgrowth (3.2%) and 1 eye conjunctival sac contracture (3.2%). Exposure of the hydroxyapatite orbital implant occurred in 1 eye (3.2%). CONCLUSIONS: Hydroxyapatite implantation in children with retinoblastoma showed good surgical results and minimal complications.

PURPOSE: To determine the value of high resolution ultrasonography (US) for the detection of hepatocellular carcinoma in the HBx transgenic mice. MATERIALS AND METHODS: Forty-two HBx transgenic mice aged 8-20 (mean, 14) months underwent high-resolution ultrasound using a 10 -12 MHz linear transducer. US findings indicating the presence or absence, number, size and echogenicity of each hepatic tumor were analyzed, and inaddition, color or power Doppler US was used to analyse tumoral vascularity. In each animal, sacrificed less than five hours after US examination, sonographic and pathologic findings were correlated. RESULT: On gross pathologic examination, 20 hepatocellular carcinomas measuring 1.5 -15 (mean, 4.7) mm in diameter were found in 16 mice; US revealed that 17 of the tumors were homogeneous hypoechoic nodules. With regard to tumor detection, sensitivity was 85%, specificity 96%, positive predictive value 0.944, negative predictive value 0.897, and overall accuracy 90%. Doppler US revealed that in three nodules, intratumoral vessels were present. Inthe other 26 mice, gross examination showed that no mass was present; microscopically, however, four nodules measuring 0.3 -1.2 mm were found in four of these animals. Tumoral vascularity detected by color Doppler US corresponded to the intratumoral vessel within the nodules. One peritoneal nodule, confirmed as a metastatic tumor, was found at the greater omentum. CONCLUSION: In HBx transgenic mice, high-resolution US is valuable for the detection of hepatocellular carcinoma.

BACKGROUND: It is known that dyslipidemia plays and important role in atherogenesis and progression for the disease. Recently it was reported that apolipoprotein levels are important in athcrogenesis. In Korean patients the study of the apolipoprotein levels as for the risk factor for atherogenesis is still needed. Subjects and METHODS: The 107 patients who underwent coronary angiography to differentiate chest pain syndrome were subjected to this study. Thirty-two patients who had no significant coronary artery disease served as a control group and 75 patients who had one or more coronary stenoses more than 50% narrowing by luminal diameter served as the coronary artery disease(CAD) group. Plasma levels of total cholesterol, triglycerides, high density lipoprotein cholestero(HDL-C), apolipoprotein A-1(Apo- A1) and apolipoprotein B(Apo B) were measured from venous blood after overnight fastion, and the results were compared between the groups. RESULTS: The male gender and smoking habits were more prevalent in the CAD group. Total cholesterol levels were significantly higher in the CAD group but the HDL-C level was not significantly different in two groups though the mean level of the HDL-C was some lower in the CAD group. The Apo A-1 level was lowere in the CAD group while the Apo B level was higher in teh CAD group compared to those of the control, Apo B / Apo A-1 ratio much more distinctly discriminated the two groups. CONCLUSION: Theses results suggest that the plasma Apo-A-1, Apo B levels and the ratio of Apo B / Apo A-1 can be used for risk statification of CAD.

Protective effect of human cerebrospinal fluid antioxidants against enzyme inactivation caused by metal-catalyzed oxidation systems were investigated. When purified glutamine synthetase(GS) was incubated with human cerebrospinal fluid(CSF), the enzyme was progressively inactivated. Catalase and EDTA could inhibit the enzyme inactivation by 50-80%. Small-molecular(Mr<-10,000) fraction of CSF inactivated the exogenous GS, but large-molecular(Mr>-10,000) fraction did not. The GS inactivation by the small-molecular fraction was also markedly inhibited by catalase and EDTA. These results suggested that metal-catalyzed oxidation is involved in the GS inactivation by the small-molecular fraction of CSF. Dithiothreitol(DTT)was shown to inhibit almost completely the oxidative inactivation of GS by CSF. However, DTT inhibited only partially the oxidative inactivation of GS caused by small-molecular fraction of CSF. When large-molecular fraction of CSF was separated by anion-exchange HPLC chromatography, there was a peak of antioxidant activity inhibiting the small-molecular fraction-induced GS inactivation in the presence of DTT. The antioxidant activity was neutralized by monoclonal antibodies to transthyretin. Purified transthyretin was found to efficiently inhibit ascorbate/Cu2+-induced GS inactivation in the presence of DTT. Uric acid and glucose did not shoe any protective effect on the GS inactivation in the same condition. The above results suggest that metal-catalyzed oxidation occurs normally in human CSF, and the transthyretin may play an important role as a CSF antioxidant in protecting proteins from metal-catalyzed oxidation.

Phlegmonous gastritis is a rare and rapidly progressive bacterial infection of the stomach wall, with a high mortality rate. Antibiotics with or without surgical treatment are required for treatment. We present a case in which phlegmonous gastritis occurred during the diagnostic evaluation of early gastric cancer. The patient showed improvement after antibiotic treatment, but attempted endoscopic submucosal dissection failed because of submucosal pus. We immediately applied argon plasma coagulation since surgical resection was also considered a high-risk procedure because of the submucosal pus and multiple comorbidities. However, there was local recurrence two years later, and the patient underwent subtotal gastrectomy with lymph node dissection. Considering the risk of incomplete treatment immediately after recovery from phlegmonous gastritis and that recurrent disease can be more difficult to manage, delaying treatment and evaluation until after complete recovery of PG might be a better option in this particular clinical situation.

OBJECTIVE: This study was performed to investigate the lipid peroxide levels and the protein carbonyl groups content in the venous plasma of pregnant women with preterm premature rupture of membranes (PPROM), non-pregnant, and normal pregnant women. METHODS: Samples of venous blood were obtained from women with non pregnancy (n=20), normal pregnancy between 25 and 37 weeks gestation (n=20), and PPROM before 37 completed weeks gestation (n=20). Lipid peroxide levels in the venous plasma of women of each group were measured by thiobarbituric acid reaction. The basal, amoxacillin and moxalactam-induced protein carbonyl contents in the venous plasma of women of each group were determined by the 2,4-dinitrophenylhydrazine (DNPH) method. RESULTS: 1. Lipid peroxide levels in the venous plasma of PPROM was significantly higher than that of non-pregnant and normal pregnant women (5.66+/-0.43 vs. 3.78+/-0.24 vs. 3.56+/-0.30 nmol/mg protein, p<0.01). 2. Protein carbonyl levels in the venous plasma of PPROM was also significantly higher than that of non-pregnant and normal pregnant women (8.23+/-0.54 vs. 6.39+/-0.23 vs. 6.54+/-0.24 nmol/mg protein, p<0.01). 3. Protein carbonyls formation by moxalactam in the venous plasma of PPROM was significantly higher than that of non-pregnant and normal pregnant women (11.73+/-0.59 vs. 10.06+/-0.26 vs. 10.10+/-0.22 nmol/mg protein, p<0.05). 4. There was no significant difference in protein carbonyls formation by amoxacillin of the venous plasma of pregnant women with PPROM, non-pregnant, and normal pregnant women (5.63+/-0.41 vs. 5.81+/-0.43 vs. 5.81+/-0.39 nmol/mg protein, p>0.05). 5. There were significant positive correlations between lipid peroxide and moxalactam-induced protein carbonyls levels of the venous plasma (p<0.05). There were no significant positive correlations between lipid peroxide and amoxacillin-induced protein carbonyls levels of the venous plasma. CONCLUSION: In the venous plasma of pregnant women with PPROM, the lipid peroxidation and the protein carbonyl formation were increased. And moxalactam-induced protein carbonyl levels were increased in PPROM. These results suggest that oxydative stress was increased in pregnant women with PPROM.
