Abstract:
By using 5'-nucleotidase-alkaline phosphatase (5'-Nase-AlPase) double staining method, the fine distribution of the lymph vessels in the stomach wall of the rabbit, guinea pig and rat has been observed. Under light microscope lymph capillaries showed strongly 5'-Nase positive reaction with brown or dark brown staining. However blood capillaries revealed significantly A1Pase activity with blue staining. The lymph capillaries were seen in all layers of the stomach wall in three species, but the lymph vessels were only shown in the submucosa, muscularis and serosa. In the mucosa lymph capillaries could be found in the deep layer of the lamina propria. In the submucosa there were lymph vessels and capillaries. In the muscularis lymph capillaries and vessels not only could be found between oblique and circular muscle or between circular and longitudinal muscle, but also among muscle fiber bundles of each layer. In the serosa there were larger lymph vessels situated near the muscularis. The observation on semithin and ultrathin sections also shown the similarity in the lymph vessels distribution. There was no difference in the distribution of lymph vessels in the stomach wall between rabbit, guinea pig and rat.
