The structural characterization and function of the stomach in the omnivore Pygocentrus nattereri were described using light and scanning electron microscopy. The sac-like stomach was morphologically divided into the cardiac and pyloric regions. The histological structure of the stomach consisted of four layers of the mucosa, submucosa, muscularis, and serosa. The superficial epithelium of the ...
To investigate the nature of the link between Helicobacter pylori (Hp) infection and stomach carcinogenesis, a study of the glandular stomach of Mongolian gerbils (MGs) was performed. MGs were treated with N-methyl-N-nitrosourea (MNU), followed by inoculation with Hp (groups 1 and 2) or without Hp (group 3), or infected with Hp (groups 4 and 5) or inoculation without Hp (group 6) followed by MN...
nism†• of carcinogenesis (3, 4,) is largely based on experimental studies on skin (6, 12, 14), though some evidence is already available for its applica bility to the thyroid gland (8, 11) and the liver (10). The extension of the problem to gastric carcinogenesis is of particular interest (a) because of the clinical importance of cancer of the stomach and the total lack of information about i...
PURPOSE To analyze mucosal proliferation and its characteristics, through specific models of duodenogastric reflux, in the stomach of Wistar rats. METHODS Seventy-five healthy and adult male rats were divided into three groups: group I--control (n = 25 animals), submitted to gastrotomy of the posterior wall of the glandular stomach; group II--DGR (n = 25 animals), submitted to duodenogastric ...
The microvascular bed of the stomach of Xenopus laevis and the changes it undergoes when the herbivorous tadpole becomes a carnivorous adult were studied by scanning electron microscopy of vascular corrosion casts and light microscopy of stained tissue sections. In tadpoles an upper and a lower gastric artery supplied, and upper, middle and lower medial and lateral gastric veins drained the ver...
