[Local blood flow in the gastric wall after proximal selective vagotomy in rats].

The influence of the proximal selective vagotomy (PSV) on the local blood flow in the gastric wall was investigated. No significant changes of the microcirculation were established in the mucosa of the corpus ventriculi (secretory area). The blood flow in the antrum pylorus was increased temporarily 24 hours after PSV and it was normalized again 4 and 7 days later. Pentagastrin led to a significant increase of the blood flow in the gastric wall of a control group and also in the operative group 24 hours after PSV. Pentagastrin was without any influence on the microcirculation after PSV are no cause for ulcer relapses.
