Rock bream (Oplegnathus fasciatus) is one of the most economically valuable fish in Korea. In recent years, artificial breeding techniques with molecular and microsatellite markers have been developed to enhance rock bream resources. Microsatellite loci to define genetic diversity were screened in rock bream (n = 30) from Jeju areas of Korea and fifteen polymorphic microsatellite loci were newly identified and analyzed. The number of alleles per locus ranged from 9 to 34 while observed and expected heterozygosity ranged from 0.600 to 1.000 and from 0.772 to 0.977, respectively. These markers will serve as a foundation for future population genetic studies and the selective breeding technology of rock bream farming.

We report colonoscopic features of an intussuscepted Meckel's diverticulum, presenting with hematochezia. A 35-year-old woman presented to the emergency room with acute onset, transient, sharp, severe epi-gastric pain that began 6 h earlier. Colonoscopy re-vealed a reddish, soft, fi st-sized polypoid lesion in the terminal ileum. The lesion was misinterpreted as a hematoma by an inexperienced endoscopist. The pa-tient began to complain of intermittent, severe peri-umbilical pain following the colonoscopic examination. Subsequent computed tomography showed an enteric intussusception. An exploratory laparotomy revealed an intussuscepted Meckel's diverticulum, with trans-mural infarction. Colonoscopy was of little use in as-sessing the intussusception. However, colonoscopic examination may be performed initially, especially in an intussuscepted Meckel's diverticulum present-ing with hematochezia. Endoscopists should note the endoscopic features of an intussuscepted Meckel's diverticulum.

To evaluate the anti-inflammatory and anti-apoptotic effects of rosuvastatin by regulation of oxidative stress in a dextran sulfate sodium (DSS)-induced colitis model. METHODSAn acute colitis mouse model was induced by oral administration of 5% DSS in the drinking water for 7 d. In the treated group, rosuvastatin (0.3 mg/kg per day) was administered orally before and after DSS administration for 21 d. On day 21, mice were sacrificed and the colons were removed for macroscopic examination, histology, and Western blot analysis. In the in vitro study, IEC-6 cells were stimulated with 50 ng/mL tumor necrosis factor (TNF)-α and then treated with or without rosuvastatin (2 μmol/L). The levels of reactive oxygen species (ROS), inflammatory mediators, and apoptotic markers were measured. RESULTSIn DSS-induced colitis mice, rosuvastatin treatment significantly reduced the disease activity index and histological damage score compared to untreated mice (P < 0.05). Rosuvastatin also attenuated the DSS-induced increase of 8-hydroxy-2’-deoxyguanosine and NADPH oxidase-1 expression in colon tissue. Multiplex ELISA analysis revealed that rosuvastatin treatment reduced the DSS-induced increase of serum IL-2, IL-4, IL-5, IL-6, IL-12 and IL-17, and G-CSF levels. The increased levels of cleaved caspase-3, caspase-7, and poly (ADP-ribose) polymerase in the DSS group were attenuated by rosuvastatin treatment. In vitro, rosuvastatin significantly reduced the production of ROS, inflammatory mediators and apoptotic markers in TNF-α-treated IEC-6 cells (P < 0.05). CONCLUSIONRosuvastatin had the antioxidant, anti-inflammatory and anti-apoptotic effects in DSS-induced colitis model. Therefore, it might be a candidate anti-inflammatory drug in patients with inflammatory bowel disease.

AIM： To correlate the clinical features of treated and untreated patients with irritable bowel syndrome （IBS） to the results of skin prick test （SPT） for food and inhalant allergens. METHODS： We recruited 105 subjects to form three different target groups： treated group （n=44） undergoing treatment for IBS, untreated group （n =31） meeting the Rome Ⅱ criteria without treatment for IBS, control group （n = 30） with no IBS symptoms. RESULTS： SPT results were different among the three groups in which SPT was positive in 17 （38.6%） treated patients, in 5 （16.1%） untreated patients and in 1 （3.3%） control （P〈0.01）. The number of positive SPTs was greater in the IBS group than in the control group （P〈 0.001）. The number of positive food SPTs was higher in the treated IBS group than in the untreated IBS group （P= 0.03）. CONCLUSION： Positive food SPT is higher in IBS patients than in controls.

AIM： To introduce and evaluate the efficacy and technical aspects of endoscopic submucosal dissection （ESD） using a novel device, the Fork knife. METHODS： From March 2004 to April 2008, ESD was performed on 265 gastric lesions using a Fork knife （Endo FS）（group A） and on 72 gastric lesions using a Flexknife （group B） at a single tertiary referral center. We retrospectively compared the endoscopic characteristics of the tumors, pathological findings, and sizes of the resected specimens. We also compared the en b/oc resection rate, complete resection rate, complications, and procedure time between the two groups. RESULTS： The mean size of the resected specimens was 4.27 ± 1.26 cm in group A and 4.29 ± 1.48 cm in group B. The en b/oc resection rate was 95.8% （254/265 lesions） in group A and 93.1% （67/72） in group B. Complete ESD without tumor cell invasion of the resected margin was obtained in 81.1% （215/265） of group A and in 73.6% （53/72） of group B. The perforation rate was 0.8% （2/265） in group A and 1.4% （1/72） in group B. The mean procedure time was 59.63 ± 56.12 min in group A and 76.65 ± 70.75 min in group B （P 〈 0.05）. CONCLUSION： The Fork knife （Endo FS） is useful for clinical practice and has the advantage of reducing the procedure time.
