[Gastric secretion and gastrin values following portocaval and splenocaval shunts in the rat]

The basal and gastrin-stimulated gastric acid output was measured in rats with a distal splenocaval shunt. In addition, serum gastrin levels were determined in rats with splenocaval and portacaval shunts. The rise in gastric acid output with increasing gastrin dosage was the same in rats with splenocaval shunt as in the controls. Serum gastrin levels were not influenced by portocaval or splenocaval shunting.
