| 1 | A case of hypereosinophilic syndrome presenting with intractable gastric ulcers显示文摘We report a rare case of hypereosinophilic syndrome(HES)presenting with intractable gastric ulcers.A 71-year-old man was admitted with epigastric pain.Initial endoscopic findings revealed multiple,active gastric ulcers in the gastric antrum.He underwent Helicobacter pylori(H pylori)eradication therapy followed by proton pump inhibitor(PPI)therapy.However,follow-up endoscopy at 4,6,10 and 14 mo revealed persistent multiple gastric ulcers without significant improvement.The proportion of his eosinophil count increased to 43%(total count:7903/mm 3).Abdominal-pelvic and chest computed tomography scans showed multiple small nodules in the liver and both lungs.The endoscopic biopsy specimen taken from the gastric antrum revealed prominent eosinophilic infiltration,and the liver biopsy specimen also showed eosinophilic infiltration in the portal tract and sinusoid.A bone marrow biopsy disclosed eosinophilic hyperplasia as well as increased cellularity of 70%.The patient was finally diagnosed with HES involving the stomach,liver,lung,and bone marrow.When gastric ulcers do not improve despite H pylori eradication and prolonged PPI therapy,infiltrative gastric disorders such as HES should be considered. | Tae Young Park Chang Hwan Choi Suh Yoon Yang InSoo Oh In-Do Song Hyun Woong Lee Hyung Joon Kim Jae Hyuk Do Sae Kyung Chang Ah Ra Cho Young Joo Cha | 2009 | World Journal of Gastroenterology2009，15，48： | 2 |
| 2 | Effects of Microstructure of Aluminum Substrate on Ordered Nanopore Arrays in Anodic Alumina显示文摘The effects of microstructure of aluminum substrate on regular nanopore arrangement in anodic alumina layer were investigated.The dissimilar microstructure and texture on aluminum sheets were prepared by various cold rollings and heat treatments,and anodic alumina nanoporous layers were fabricated by two step anodizing method at 40 V in oxalic acid solution.For the aluminum sheets with similar surface texture and annealing condition except purity,the regularity of the nanopore arrangement on the anodic alumina layer increased with purity of aluminum substrate.The difference of surface texture on Al sheets is not critical parameter for formation of ordered nanopore array compared with purity and heat treatment of substrate aluminum.The investigation suggested that the purity and reasonable annealing temperature of aluminum substrate are very important process to obtain the highly-ordered nanopore array on anodic alumina layer. | Choong-Soo Chi Jong-Ho Lee Insoo Kim Han-Jun Oh | 2015 | Journal of Materials Science & Technology2015，31，7： | 0 |
