Gastric content of the liquid test meals in rats with gastrointestinal neoplasias induced by N-methyl-N-nitrosoguanidineand 1,2-dimethylhydrazinePokorn, Dražigost ; Hlastan-Ribič, Cirila ; Cerar, Anton, 1945-We hypothesized that liquid test meal without a calorific value injected directly into the rats stomach by a sonde, may be emptied from the stomach both with and without gastrointestinal tumours at ... different rate. We tested hypothesis using the dye dilution test for gastric emptying. Intestinal tumours (adenoma, adenocarcinoma) in male Wistar rats at different dieting regime were experimentally induced by 1,2-dimethylhydrazine (DMH). Gastric andduodenal tumours in male Wistar rats at different dieting regime were experimentally induced by N-methyl-N-nitrosoguanidine (MNNG). We noticed statistically higher gastric content after applicating the test meal in the stomach of rats with duodenal tumours in comparison with the group of rats both with gastric tumours (p<0.01) or without gastric tumours (p<0.001). Remained gastric content of rats tested with intestinal tumours was not statistically significant in comparison with remained gastric content of rats with (p= 0.901) or without gastric tumours (p= 0.406). We postulate that the role of duodenal resistance in controlling liquid gastric emptying in rats hasprinciple importance if the test meal is instillated into the stomach with or without tumours through a tube. The tumours of colon have no any effect on the stomach, particularly on gastric emptying of liquid meals instillated in rat stomach. Only duodenal tumours and duodenal pathohistological changes interfered gastric emptying.Vir: International journal of cancer research. - ISSN 1811-9727 (Letn. 2, št. 1, 2006, str. 19-30)Vrsta gradiva - članek, sestavni delLeto - 2006Jezik - angleškiCOBISS.SI-ID - 20838617
