Experimental analysis of gastric mucosal blood flow after transient forebrain ischemia

Gastric mucosal blood flow (GMBF) was measured by a laser doppler flow meter continually during and after transient forebrain ischemia in rats. The value of GMBF obtained after at 15 min of ischemia did not change significantly compared to that of the preischemic period. However, a 26% decrease of GMBF was detected after 30 min of ischemia. When circulation of the brain was restored, the GMBF increased slightly after 15 min. After 30, 45, and 60 min of restored cerebral circulation, the GMBF decreased significantly and the values were 63%, 58% and 51% of the control, respectively.
