[Regional gastric blood flow in hypovolemic shock in rats]

The effect of hypovolemia on the mucosal blood flow of gastric corpus and antrum were tested with the microspheres method 30 and 60 min after induction of shock in the rat. The results demonstrate a marked reduction after 30 min, with return to control values after 60 min, without any significant differences between corpus and antrum. It is concluded that the differences in energy metabolism between these two regions of gastric mucosa, cannot be attributed to different degrees of ischemia.
