Amyand's Hernia diagnosed preoperatively via a CT scan: A case report.

Amyand's hernia is a rare type of inguinal hernia characterized by the presence of the vermiform appendix within the hernia sac. It was named after Claudius Amyand who performed the world's first successful appendectomy on an 11-year-old boy with a right inguinal hernia in 1735 and discovered a herniated appendix during surgery. This condition warrants urgent surgical treatment, with the type of surgical intervention depending on the appendix's condition.

A 55-year-old man suffering from melena was admitted to our hospital. A blood test showed severe anemia. Contrast-enhanced computed tomography (CT) revealed a huge lesion in the duodenum and dilatation of the common bile duct.

Cloning, polymorphism, and inhibition of beta-carbonic anhydrase of Helicobacter pylori.

Background: Carbonic anhydrase (CA) catalyzes the reversible hydration of CO(2) to bicarbonate and a proton, and alpha-class CA has been reported to facilitate the acid acclimation of Helicobacter pylori (hpalphaCA). The purpose of this study was to characterize the beta-class CA of H. pylori (hpbetaCA) and elucidate the role of this enzyme as a possible drug target for eradication therapy.
