A bstract The venerid clam(M actra veneriformis Reeve 1854) is one of the main cultured bivalve species in intertidal and shallow subtidal ecosystems along the west coast of Korea. To understand the effects of ocean acidifi cation on the early life stages of Korean clams, we investigated shell growth and abnormality rates and types in the D-shaped, umbonate veliger, and pediveliger stages of the venerid clam M. veneriformis during exposure to elevated seawater pCO_2. In particular, we examined abnormal types of larval shell morphology categorized as shell deformations, shell distortions, and shell fi ssures. Specimens were incubated in seawater equilibrated with bubbled CO_2-enriched air at(400±25)×10^(-6)(ambient control),(800±25)×10^(-6)(high pCO_2), or(1 200±28)×10^(-6)(extremely high pCO_2), the atmospheric CO_2 concentrations predicted for the years 2014, 2084, and 2154(70-year intervals; two human generations), respectively, in the Representative Concentration Pathway(RCP) 8.5 scenario. The mean shell lengths of larvae were signifi cantly decreased in the high and extremely high pCO_2 groups compared with the ambient control groups. Furthermore, under high and extremely high pCO_2 conditions, the cultures exhibited signifi cantly increased abundances of abnormal larvae and increased severity of abnormalities compared with the ambient control. In the umbonate veliger stage of the experimental larvae, the most common abnormalities were shell deformations, distortions, and fi ssures; on the other hand, convex hinges and mantle protuberances were absent. These results suggest that elevated CO_2 exerts an additional burden on the health of M. veneriformis larvae by impairing early development.

World Journal of Gastroenterology 2009年第8期15卷 973-977页

作者： Hye Suk Hwang Kyung-Ju Han Yeon Hee Ryu eun jin yang Yoo Sung Kim Sang Yong Jeong Young-Seop Lee Myeong Soo Lee Sung Tae Koo Sun-Mi Choi Department of Medica Research Korea Institute of Oriental Medicine Daejeon 305-811 South Korea Division of Meridian and Structural Medicine School of Oriental Medicine Pusan National University Pusan 609-735 South Korea

AIM: To investigate the protective effects of electroacupuncture (EA) pretreatment on acetylsalicylic acid (ASA)-induced ulceration in rats. METHODS: We randomly divided 72 rats into three groups including control (administered with distilled water), ASA group (administered 100 mg/kg ASA) and EA group (administered EA + 100 mg/kg ASA). Each rat was fasted for 18 to 24 h before experimentation, and lesion scores, gastric acidity, cyclooxygenase (COX)-1 and -2 mRNA levels, and total nitric oxide (NO) concentration were measured. RESULTS: The lesion scores of the EA group were significantly lower than those of the ASA group. Gastric acidity of the ASA and EA groups was reduced compared to the control group. COX-1 and -2 mRNA levels were significantly increased in the EA group as compared to the control and ASA groups, and NO levels were also significantly increased in the EA group as compared to the ASA group. CONCLUSION: These results suggest that EA-mediated protection against ASA-induced ulceration in rats may occur via gastric defense components.

Marine ciliate community in relation to eutrophication of coastal waters in the Yellow Sea

引用

Chinese Journal of Oceanology and Limnology 2011年第1期29卷 118-127页

作者：徐奎栋 CHOI Joong Ki 类彦立 yang eun jin Institute of Oceanology Chinese Academy of Sciences Department of Oceanography Inha University Korea Polar Research Institute

We assessed the potential of marine ciliate community as an indicator to coastal water quality using water samples collected from four stations in thc Yellow Sea in the summer 2000. The four stations were characterized by different levels of pollution. The ciliate communities consisted primarily of tintinnids and aloricate ciliates that were 〈30 um. A total of 78 species were classified： 55 species at Station 2, 51 species each at Stations l and 4, and 47 species at Station 3. The mean number of species at each site was 29.2±2.0 （Station 1）, 28.5±2.9 （Station 2）, 27.8±1.7 （Station 3）, and 24.5±2.3 （Station 4）. The abundance was highly variable： 19 331±11 187 ind./L at Station 1, 7 960±5 639 ind./L at Station 2, 29 015±12 999 ind./L at Station 3, and 8 190±4 658 ind./L at Station 4. Our results suggest that neither the simple chemical analysis （e.g. chemical oxygen demand, dissolved inorganic nitrogen, and phosphate） nor the eutrophication/pollution index adequately described the water quality at the four stations. The same was true of the number of species and their abundance, both of which had no correlation with the chemical indices. In contrast, Margalef＇s diversity index values （3.12 at Station 2, 2.89 at Station 1, and 2.64 at Stations 3 and 4） generally discriminated the water quality status of the four stations. The difference in water quality among the stations was strongly supported by the pattern of species richness （i.e. the total number of species） of ciliates at each station. Our evaluation was consistent with the results of long-term water quality monitoring at the four stations. With increasing eutrophication, we observed also a compositional and functional shift in the ciliate assemblages from algivorous oligotrich/choreotrich to nonselective-omnivorous gymnostomatids to bacterivorous-detrivorous scuticociliatids. Thus, eiliates may be used to indicate the coastal water quality status of a given site.

Pancreatic fistula after pancreaticoduodenectomy:A comparison between the two pancreaticojejunostomy methods for approximating the pancreatic parenchyma to the jejunal seromuscular layer:Interrupted vs continuous stitches

引用

World Journal of Gastroenterology 2007年第40期13卷 5351-5356页

作者： Seung eun Lee Sung Hoon yang jin-Young Jang Sun-Whe Kim Department of Surgery Seoul National University College of Medicine28 Yongon-dongChongno-guSeoul 110-744Korea

AIM： The purpose of this study is to find a better operative technique by comparing interrupted stitches with continuous stitches for the outer layer of the pancreaticojejunostomy, i.e. the stitches between the stump parenchyma of the pancreas and the jejunal seromuscular layer, and other risk factors for the incidence of pancreatic leakage.METHODS： During the period January 1997 to October 2004, 133 patients have undergone the end-to-side and duct-to-mucosa pancreaticojejunostomy reconstruction after pancreaticoduodenectomy with interrupted suture for outer layer of the pancreaticojejunostomy and 170 patients with a continuous suture at our institution by one surgeon.RESULTS： There were no significant differences between the two groups in the diagnosis, texture of the pancreas, use of octreotide and pathologic stage. Pancreatic fistula occurred in 14 patients （11%） among the interrupted suture cases and in 10 （6%） among the continuous suture cases （P = 0.102）. Major pancreatic leakage developed in three interrupted suture patients （2%） and zero continuous suture patients （P = 0.026）. In multivariate analysis, soft pancreatic consistency （odds ratio, 5.5; 95% confidence interval 2.3-13.1） and common bile duct cancer （odds ratio, 3.7; 95%CI 1.6-8.5） were＇predictive of pancreatic leakage.CONCLUSION： Pancreatic texture and pathology are the most important factors in determining the fate of pancreaticojejunal anastomosis and our continuous suture method was performed with significantly decreased occurrence of major pancreatic fistula. In conclusion, the continuous suture method is more feasible and safer in performing duct-to-mucosa pancreaticojejunostomy.

Intraductal papillary mucinous carcinoma with atypical manifestations:Report of two cases

引用

World Journal of Gastroenterology 2007年第10期13卷 1622-1625页

作者： Seung eun Lee jin-Young Jang Sung Hoon yang Sun-Whe Kim Department of Surgery Seoul National University College of MedicineSeoulKorea

Intraductal papillary mucinous neoplasms （IPMNs） are a well-characterized group of rnucin-producing cystic neoplasms of the clear malignant potential type. We report here two cases of intraductal papillary mucinous carcinoma （IPMC） with atypical manifestations. In one case, we discussed a pseudomyxoma peritonei caused by a ruptured IPMC. In the other case we discussed the fistulization of IPMC into the stomach and duodenum. These two cases suggest that IPMN can either spontaneously rupture causing mucinous materials to spill into the free abdominal cavity or directly invade adjacent organs resulting in fistula development.
