Inhibition of glucagon improves splanchnic hyporesponse to terlipressin in cirrhotic rats with blood retention in the gastric lumen

Intragastric blood gavage induced an elevation of plasma glucagon level and led to a splanchnic hyporesponse to terlipressin. Glucagon antiserum or octreotide administration overcame this hyporesponse. Excessive release of circulating glucagon may be an important factor for splanchnic hyporesponse to terlipressin in cirrhotic portal hypertension during hemorrhage.
