INTRODUCTION Hepatoid adenocarcinoma (HAC) is a rare neoplasm with a striking morphologic similarity to hepatocellular carcinoma. The most common sites of HAC are the stomach, lung, and pancreas. CASE REPORT Here we report a rare case of HAC arising from the heterotopic pancreas (Heinrich type II) in the ileum with lymph node metastasis. A 56-year-old man was admitted to our hospital presenti...

Diazinon (DZN) is an organophosphate insecticide which exerts its effect through the inhibition of acetylcholinesterase enzyme (AChE). In this work, we studied the development of tolerance to subchronic p.o. administration of DZN in rats, under both in vivo and in vitro conditions. A group of 20 rats (2 groups, n = 10) was administered p.o. the 1/10 of established LD50 DZN (namely 55.87 mg/kg b...

A 7-month-old boy was admitted to our clinic with apparently painless rectal bleeding. No abnormality was detected on physical examination. Erythrocyte and technetium-99m scintigraphy gave negative results. The first episode lasted about 18 hours. A second episode occurred a month later. This time both scintigraphic studies were positive for bleeding Meckel’s diverticulum. Laparotomy was perfor...

Seeds of Moringa peregrina (Forssk.) Fiori. (Moringaceae) is widely used in south east of Iran for gastrointestinal disorders. However, so far there is no pharmacological evidence for antispasmodic activity of this plant extract. Therefore, the aim of this research was to investigate antispasmodic activity of M. peregrina on rat isolated ileum contraction. Hydroalcoholic extract was obtained by...

Celery (Apium graveolens L.) is a plant species in the family Apiaceae, which has been used in traditional medicine for the treatment of gastrointestinal diseases. This study investigated the effects of aqueous and ethanol extracts from celery leaves on intestinal contractility. Air-dried and powdered leaves were extracted with distilled water and 96% ethanol, respectively. The activities of th...

We have previously elucidated the opiate-like action of mitragynine, an active principle isolated from the Thai medicinal plant Mitragyna speciosa. In the present study, effects of the related compound, mitragynine pseudoindoxyl on electrically stimulated contraction in guinea pig ileum and mouse vas deferens, and on its binding affinity in the guinea pig brain membranes were studied. Mitragyni...

Anethum graveolens L. is a member of the Apiaceae family and more commonly known as dill. Dill has been used for gastrointestinal ailments such as flatulence, indigestion, stomach ache and colic. It has therapeutic effects such as mucosal protective, antisecretory, antimicrobial, antispasmodic, antihypercholesterolaemic and antihyperlipidaemic. The aim of our study was to examine the effects of...

Bacterial diversity of the mucosal biopsies from human jejunum, distal ileum, ascending colon and rectum were compared by analysis of PCR-amplified 16S rDNA clone libraries. A total of 347 clones from the mucosal biopsies were partially sequenced and assigned to six phylogenetic phyla of the domain Bacteria: Firmicutes, Bacteroidetes, Proteobacteria, Fusobacteria, Verrucomicrobia, and Actinobac...

The effects of serosally added 5-hydroxytryptamine (5-HT, 100 microM) on the short circuit-current (Isc) across jejunum and ileum taken from fed, starved and undernourished (Gerbillus cheesmani) were investigated. The effects of the neurotoxin, tetrodotoxin (TTX, 10 microM) on the basal Isc as well as on the maximum increase in Isc induced by 5-HT were also studied. There were regional variatio...
