| evidence for gastric mucosal cell invasion by c. pylori: an ultrastructural study. | it is now generally accepted that campylobacter pylori is closely associated with peptic ulcer disease and chronic type b gastritis. whether c. pylori is the direct etiologic cause of either or both of these illnesses remains unclear. possible pathophysiologic effects of c. pylori are still a matter of debate and conjecture. utilizing a small group of patients with gastric ulcers and chronic gastritis, we examined the ultrastructural relationship between c. pylori and gastric cells. forty-eight ... | 1990 | 2212556 |
| campylobacter pylori interactions with gastric cell tissue culture. | many investigators have reported that gastric mucosal biopsies of patients with chronic gastritis and peptic ulcer disease show the presence of campylobacter pylori in a large majority of cases. histologic examinations of such tissues indicate a close approximation of c. pylori with gastric surface epithelial cells. a recent report has described both adherence and cell invasion of gastric cells by c. pylori. using a transmission electron microscope, we have examined the interaction between c. py ... | 1990 | 2212557 |
