Objectives To evaluate the accuracy of double contrast-enhanced ultrasonography (DCEUS) in preoperative Borrmann classification of advanced gastric cancer (AGC). Materials and Methods A total of 162 patients histologically confirmed AGC were enrolled into this study. Single oral contrast-enhanced ultrasonography (SOCEUS) were performed in 80 patients and DCEUS (intravenous microbubbles combin...

Introduction: Neuroendocrine tumors develop throughout gastrointestinal tract. The concurrence of mixed adenocarcinoma and neuroendocrine tumor together in the stomach is rare. Case report: We report two cases of poorly differentiated carcinoma stomach with neuroendocrine component. These patients underwent radical total gastrectomy with D2 lymph node dissection followed by adjuvant chemotherap...

Gastroduodenal motility has been described in several avian species. In domestic turkeys (Melagridis gallapavo; Duke et al. 1972, Dziuk and Duke 1972), chickens (Gallus gallus; Roche et al. 1971), Cedar Waxwings (Bombycilla cedorum; Levey and Duke 1993), and Leach's Storm-Petrels (Oceanodroma leuchoroa; Duke et al. 1989), the sequence begins with contraction of the pair of thin muscles of the m...

The potential reversibility of glandular stomach lesions induced by the clastogen, catechol, was examined in groups of male F344 rats treated continuously with 0.8% catechol in the diet for 12, 24, 48, 72, or 96 weeks. After a return to basal diet for 84, 72, 48, 24, and 0 weeks, respectively, the animals were killed for histopathological examination. Incidences of submucosal hyperplasia, adeno...

Introduction Some effects of 13adrenoceptor agonists on gastrointestinal motility have been investigated in monogastric species (Burks, 1987). Several side effects of /3-blockers are mediated through the central nervous system which is involved in the control of gastrointestinal motility. This study was undertaken to determine the central and peripheral actions of /3!and P2agonists on forestoma...

Both connective tissue mast cells and mast cells grown in vitro are derived from multipotential hematopoietic stem cells, but these two mast cell populations exhibit many differences in morphology, biochemistry, and function. We investigated whether the phenotype of cultured mast cells or their progeny was altered when the cells were transferred into different locations in vivo. Cultured mast c...
