[Gastric blood flow in animals. I. Normal blood flow (author's transl)].

Total and regional gastric blood flow were measured in 15 dogs under control conditions (mean AOBP 100 mm Hg) using microspheres labelled with different isotopes (125J, 141Ce, 85Str, 46Sc) of 8 mu size. The mucosa in fundus and corpus showed significantly higher blood flow compared to the antrum. There was no difference in the muscular layer for either part of the stomach. It is concluded from these data that differences in regional blood flow in the unstimulated stomach of the dog are related to different energy-demands within the stomach.
