作者： Seong Yong Woo Jin Il Kim Dae Young Cheung Se Hyun Cho Soo-Heon park joon-Yeol Han Jae Kwang Kim Division of Gastroenterology and Hepatology Department of Internal Medicine the Catholic University of Korea

AIM: To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis ***: The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were ***: Fitz-Hugh-Curtis syndrome was identified in 22 female patients of childbearing age; their mean age was 31.0 ± 8.1 years. Fourteen of these cases presented with pain in the upper right abdomen alone or together with pain in the lower abdomen, and six patients presented with pain only in the lower abdomen. The first impression at the time of visit was acute cholecystitis or cholangitis in 10 patients and acute appendicitis or pelvic inflammatory disease in eight patients. Twenty-one patients were diagnosed by abdominal computer tomograghy (CT), and the results of abdominal sonography were normal for 10 of these patients. Chlamydia trichomatis was isolated from 18 patients. Two patients underwent laparoscopic adhesiotomy and 20 patients were completely cured by antibiotic ***: For women of childbearing age with acute pain in the upper right abdomen alone or together with pain in the lower abdomen, Fitz-Hugh-Curtis syndrome should be considered during differential diagnosis. Moreover, in cases suspected to be Fitz-Hugh-Curtis syndrome, abdominal CT, rather than abdominal sonography, assists in the diagnosis.

Tensile creep and corrosion properties of Mg-2%Ca based cast alloys

引用

Transactions of Nonferrous Metals Society of China 2011年第4期21卷 869-873页

作者： Jeong-Min KIM joon-Sik park Ki-Tae KIM Division of Advanced Materials Engineering Hanbat National University Incheon R&D Center Korea Institute of Industrial Technology

The relative effect of Zn addition to Mg-2%Ca based alloy on the creep and corrosion characteristics was compared with Al addition. The creep resistance of Mg-2%Ca based alloy at 175 ℃was improved by Zn addition more significantly than by Al addition. However, the Al addition showed more effective in enhancing corrosion resistance. Since the solidification range for Zn-added alloy was considerably wide, the cautious casting design may be necessary to produce high-quality castings.

AIM:To explore the feasibility of pertorming minimally invasive surgery(MIS)on subsets of submucosal gastric cancers that are unlikely to have regional lymph node metastasis. METHODS:A total of 105 patients underwent radical gastrectomy with lymph node dissection for submucosal gastric cancer at our hospital from January 1995 to December *** investigating many clinicopathological features such as tumor size,gross appearance,and differentiation, we measured the depth of invasion into submucosa minutely and analyzed the clinicopathologic features of these patients regarding lymph node metastasis. RESULTS:The rate of lymph node metastasis in cases where the depth of invasion was2 000 μm was 9%(2/23),19%(7136),and 33%(15/46), respectively(P4 cm vs≤2 cm,odds ratio=4.80, P=0.04)and depth of invasion(>2 000 μm vs ≤500 μm, odds ratio=6.81,P=0.02)were significantly correlated with lymph node *** the depth and size in cases where the depth of invasion was less than 500 μm, we found that lymph node metastasis occurred where the tumor size was greater than 4 *** cases where the tumor size was less than 2 cm,lymph node metastasis was found only where the depth of tumor invasion was more than 2 000 μm. CONCLUSION:MIS can be applied to submucosal gastric cancer that is less than 2 cm in size and 500 μm in depth.

Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy

引用

World Journal of Gastroenterology 2009年第34期15卷 4298-4304页

作者： Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun park Tae Hoon Lee Hyun Jong Choi Sang-Heum park joon Seong Lee Moon Sung Lee Institute for Digestive Research Digestive Disease Center Soonchunhyang University College of Medicine

AIM： To compare small sphincterotomy combined with endoscopic papillary large balloon dilation （SES ＋ ELBD） and endoscopic sphincterotomy （EST） for large bile duct stones. METHODS： We compared prospectively SES ＋ ELBD （group A, n = 27） with conventional EST （group B, n = 28） for the treatment of large bile duct stones （≥ 15 mm）. When the stone could not be removed with a normal basket, mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS： No significant differences were observed in the mean largest stone size （A： 20.8 mm, B： 21.3 mm）, bile duct diameter （A： 21.4 turn, B： 20.5 ram）, number of stones （A： 2.2, B： 2.3）, or procedure time （A： 18 min, B： 19 rain） between the two groups. The rates of complete stone removal with one session was 85% in group A and 86% in group B （P = 0.473）. Mechanical lithotripsy was required for stone removal in nine of 27 patients （33%） in group A and nine of 28 patients （32%, P = 0.527） in group ***： SES ＋ ELBD did not show significant benefits compared to conventional EST, especially for the removal of large （≥ 15 mm） bile duct stones.

Nardostachys jatamansi extract protects against cytokine-induced β-cell damage and streptozotocin-induced diabetes

引用

World Journal of Gastroenterology 2010年第26期16卷 3249-3257页

作者： Mi-Young Song Ui-Jin Bae Bong-Hee Lee Kang-Beom Kwon Eun-A Seo Sung-Joo park Min-Sun Kim Ho-joon Song Keun-Sang Kwon Jin-Woo park Do-Gon Ryu byung-Hyun park Department of Biochemistry Medical School and Diabetes Research Center Chonbuk National University Jeonju Jeonbuk 561-756 South Korea Department of Physiology School of Oriental Medicine Wonkwang University Iksan Jeonbuk 570-749 South Korea Department of Food and Nutrition School of Human Environmental Science Wonkwang University Iksan Jeonbuk 570-749 South Korea Department of Herbology School of Oriental Medicine Wonkwang University Iksan Jeonbuk 570-749 South Korea Department of Preventive Medicine Medical School Chonbuk National University Jeonju Jeonbuk 561-756 South Korea

AIM: To investigate the anti-diabetogenic mechanism of Nardostachys jatamansi extract (NJE). METHODS: Mice were injected with streptozotocin viaa tail vein to induce diabetes. Rat insulinoma RINm5F cells and isolated rat islets were treated with interleukin1β and interferon-γ to induce cytotoxicity. RESULTS: Treatment of mice with streptozotocin resulted in hyperglycemia and hypoinsulinemia, which was conf irmed by immunohistochemical staining of the islets. The diabetogenic effects of streptozotocin were completely abolished when mice were pretreated with NJE. Inhibition of streptozotocin-induced hyperglycemia by NJE was mediated by suppression of nuclear factor (NF)-κB activation. In addition, NJE protected against cytokine-mediated cytotoxicity. Incubation of RINm5F cells and islets with NJE resulted in a signif icant reduction in cytokine-induced NF-κB activation and downstream events, inducible nitric oxide synthase expression and nitric oxide production. The protective effect of NJE was further demonstrated by the normal insulin secretion of cytokine-treated islets in response to glucose. CONCLUSION: NJE provided resistance to pancreatic β-cell damage from cytokine or streptozotocin treatment. The β-cell protective effect of NJE is mediated by suppressing NF-κB activation.
