[Experimental conditions for the reproduction of a submucous steal phenomenon in the dog stomach].
The influence of pentagastrin on gastric blood flow has been investigated using 9 mu-microspheres in dogs. As soon as 6 min after the onset of a pentagastrin infusion blood flow rises in all gastric probes in fasted animals. In dogs, fed two hours previously, such a response can only be seen in the corpus-mucosa areas. Blood flow in the antrum mucosa specimen falls beneath its initial value. This gastric steal-phenomenon takes place at the level of the submucous plexus, as has been shown earlier.
