Acidic mucins such as sialomucin and sulfomucin produced by intestinal epithelial cells have been implicated in the protection of the mucosa from pathogens. In the present study, we analyzed the alteration of acidic mucins in the jejunum of euthymic and athymic rats infected with the nematode Nippostrongylus brasiliensis using alcian blue staining and a(More)
To determine how T cells of thymic origin regulate the intestinal mucous response induced by nematode infection, mucin production and goblet cell-specific secretory peptide expression were examined in euthymic rnu/+ and athymic rnu/rnu rats infected with the nematode Nippostrongylus brasiliensis. Euthymic rats showed transient goblet cell hyperplasia and(More)
INTRODUCTION Multi-row detector computed tomography (MDCT) and magnetic resonance cholangiopancreatography (MRCP) play an important role in the imaging diagnosis of hepatobiliary-pancreatic lesions. Here we investigated whether unifying the MDCT and MRCP images onto the same screen using fusion imaging could overcome the limitations of each technique, while(More)
BACKGROUND/AIMS Ruptured esophagogastric varices are commonly associated with bleeding in patients with portal hypertension. However, the prediction of esophageal variceal bleeding is not matched by means of predicting gastric variceal bleeding. The present study aim is to elucidate risk factors for gastric variceal bleeding. METHODOLOGY Twelve patients(More)
We present the case of a patient who was referred to our hospital after she reported having passed a long, whitish object per rectum. Accordingly, capsule endoscopy was performed using the PillCam(®) SB video capsule. A tapeworm of the species Diphyllobothrium nihonkaiense was detected; it appeared to be freely floating and unfolded in the jejunum and(More)
The patient was a 66-year-old woman who had undergone laparoscopic cholecystectomy (Lap-C) secondary to chronic cholecystitis status post endoscopic choledocholithotomy 13 months previously. During surgery, Hem-o-Lok clips were used to control the cystic duct and the cystic artery. Due to the presence of extensive adhesions of the cystic duct and(More)
A 46-year-old man was admitted to our hospital following hematemesis. Emergency direct-viewing gastroduodenoscopy revealed fresh bleeding from the major duodenal papilla. Further examination of both papillae by sideviewing endoscopy confirmed fresh bleeding from both the major and minor papillae (Fig. 1). Ultrasound and computed tomography (CT) revealed a(More)
This review examines the use of digestive endoscopy to visualize intestinal helminths. The infections caused by these parasites are responsible for high levels of morbidity and mortality. These helminths can be visualized using gastroduodenal endoscopy, endoscopic retrograde cholangiopancreatography, and colonoscopy. Endoscopic examination of the small(More)
A 68-year-old man with hemophilia A and liver cirrhosis caused by hepatitis C virus was referred to our hospital to receive prophylactic endoscopic treatment for gastroesophageal varices (GOV). He had large, tense, and winding esophageal varices (EV) with cherry red spots extending down to lesser curve, predicting the likelihood of bleeding. Esophageal(More)
