This paper describes a new technique for the closure of oro-antral fistula/communication, in which both hard tissue (bone) and soft tissue closure is achieved. The sandwich technique utilizes a suitable bone grafting material sandwiched between two sheaths of Biogide (a resorbable membrane) for the hard tissue closure of oro-antral communication post traumatic exodontia. The bone grafting mater...

We describe the clinical scenario of a young male with history of non ulcer dyspepsia who had endoscopic evidence of gastric polyposis in antral area. The polyps disappeared four months after proton pump inhibitors were stopped. Proton pump inhibitors have been linked to gastric fundal polyposis and not antral gland polyposis. This is the first report originating from an Asian country describin...

=Abstract=The effects of dopamine on gastric motility were investigated using circular muscle strips prepared from the antral and' fundic regions of the guinea-pig stomachs. The spontaneous and phasic contractions induced by electrical stimulation were recorded with a force transducer. Dopamine potentiated the spontaneous contraction of the antral circular muscle, which was suppressed completel...

The pesticide methoxychlor (MXC) is a reproductive toxicant that targets antral follicles of the mammalian ovary. Cytochrome P450 enzymes metabolize MXC to mono-OH MXC (1,1,1-trichloro-2-(4-hydroxyphenyl)-2-(4-methoxyphenyl)ethane [mono-OH]) and bis-OH MXC (1,1,1-trichloro-2,2-bis(4-hydroxyphenyl)ethane [HPTE]), two compounds that are proposed to be more toxic than the parent compound, can inte...

Background: Helicobacter pylori is the most common chronic bacterial infection, and a significant etiological factor in acid peptic diseases and gastric cancer. Dyspepsia is a common gastrointestinal disorder, and the most common indication for gastroscopy. Detection of H. pylori during endoscopy has become standard clinical practice. Elevated levels of inflammatory markers such as C-reactive p...

PURPOSE To describe the CT and MR findings of various entities causing cystic expansile masses in the maxilla and the significance of the cortical bony plate between the lesions and sinus cavities in the differential diagnosis. METHODS CT findings of 28 patients with cystic expansile masses of the maxilla, including 20 cases of maxillary mucoceles (17 postoperative mucoceles, 2 mucoceles of a...

Gastric acid exerts a feedback inhibition on the secretion of gastrin from antral G cells. This study examines whether gastrin gene expression is also regulated by changes in gastric pH. Achlorhydria was induced in rats by the gastric H+/K+ ATPase inhibitor, omeprazole (100 mumol/kg). This resulted in fourfold increases in both serum gastrin (within 2 h) and gastrin mRNA levels (after 24 h). An...

This study aimed to examine the association between Helicobacter pylori, histological gastritis, and intestinal metaplasia in gastric cancers of different histological types. A total of 169 gastrectomy specimens received in one pathology department were studied. Altogether 156 were adenocarcinomas (intestinal type 87, diffuse type 50, mixed type 19). Gastritis occurred in 137 of 163 body specim...

Energy metabolism in gastrobiopsy specimens of the antral and corpus mucosa, treated with saponin to permeabilize the cells, was studied in patients with gastric diseases. The results show twice lower oxidative capacity in the antral mucosa than in the corpus mucosa and the relative deficiency of antral mitochondria in complex I. The mucosal cells expressed mitochondrial and cytosolic isoforms ...
