Bacterial Reverse Mutation Test of Verbenalin.

Objectives: Verbenalin is a compound found in herbs such as and . This study investigated whether verbenalin is safe by analyzing its mutagenicity.

Methods: To examine the mutagenic potential of verbenalin, a bacterial reverse mutation test (Ames test) was conducted with and strains.

Improving methane mitigating functionality of blast furnace slag by adding electron acceptor.

Blast furnace slag (BFS), a byproduct of iron-producing process, has been applied as silicate fertilizer in rice paddy. Silicate fertilizer contains lime and silicate as main components and iron and manganese as electron acceptors. This amendment improves soil productivity and mitigates methane (CH) emissions.

Introduction of a Program to Improve the Information Sharing System of Food Allergy Patients.

Although the symptoms of food allergy are diverse and sometimes dangerous to life, we have not been able to effectively share information on patients' food allergies. In this study, we developed a program to prescribe the allergic formula for each patient and to establish a series of processes for safe allergenic meal delivery based on the standards and guidelines of food allergy management. We then assessed the utility of the "introduction of food allergy program" by comparing the number of allergic prescriptions before and after the program application for inpatients.

Endoscopic Extraction of Biliary Fascioliasis Diagnosed Using Intraductal Ultrasonography in a Patient with Acute Cholangitis.

Fasciola hepatica infection may result in biliary obstruction with or without cholangitis in the chronic biliary phase. Because clinical symptoms and signs of F. hepatica are similar to other biliary diseases that cause bile duct obstruction, such as stones or bile duct malignancies, that are, in fact, more common, this condition may not be suspected and diagnosis may be overlooked and delayed.

Direct insertion of an ultra-slim upper endoscope for cholangioscopy in patients undergoing choledochoduodenostomy.

Direct peroral cholangioscopy (POC) using an ultra-slim upper endoscope is one modality of POC for intraductal endoscopic evaluation and treatment of the bile duct. Choledochoduodenostomy (CDS) is one modality of biliary bypass surgery that provides a new route to the bile duct. We carried out direct POC using an ultra-slim upper endoscope without the use of accessories in 10 patients (four sump syndromes, three bile duct strictures and three intrahepatic duct stones) previously undergoing surgical CDS.

Comparison of endoscopic papillary balloon dilation and sphincterotomy in young patients with CBD stones and gallstones.

Background And Aims: Endoscopic biliary sphincterotomy (EBS) results in permanent loss of sphincter function and its long-term complications are unknown. Endoscopic papillary balloon dilation (EPBD) is an alternative procedure that preserves sphincter function, although it is associated with a higher risk of pancreatitis than is EBS. The aim of this study was to evaluate the safety and outcomes of EPBD with limited indications for removal of common bile duct (CBD) stones combined with gallstones in patients younger than 40 years.

[Therapeutic outcomes of endoscopic submucosal dissection in undifferentiated-type early gastric cancer].

Background/aims: Endoscopic submucosal dissection (ESD) has been accepted as a standard treatment of early gastric cancer (EGC). However, the indication of ESD in undifferentiated-type EGC was controversial. The aim of this study was to evaluate the therapeutic outcomes of ESD in undifferentiated-type EGC according to expanded indication.
