title: [Plasma level of glucagon in cirrhotic patients with portal hypertension during operation of portacaval shunts].
abstract: OBJECTIVE
  To investigate the plasma level of glucagon in cirrhotic patients with portal hypertension during operation of portacaval shunts.
  
  
  METHODS
  Plasma level of glucagon in the portal venous, peripheral venous and arterial blood in cirrhotic patients (n = 16) and control patients (n = 16) was measured by radioimmunoassay respectively.
  
  
  RESULTS
  The glucagon ratio (pg/ml) of the hepatic cirrhosis group before, during after operation 3 days after operation, 7 days after operation was observed portal venous blood: (189.2 +/- 58.7) pg/ml, (196.1 +/- 54.2) pg/ml vs. (101.9 +/- 44.8) pg/ml, (98.2 +/- 34.1) pg/ml (P < 0.01); peripheral venous blood (184.1 +/- 48.2) pg/ml, (187.5 +/- 42.8) pg/ml vs. (102.4 +/- 34.7) pg/ml, (95.2 +/- 24.9) pg/ml (P < 0.01); arterial blood: (186.3 +/- 51.3) pg/ml, (183.5 +/- 54.2) pg/ml vs. (103.4 +/- 36.3) pg/ml, (93.9 +/- 30.6) pg/ml (P < 0.01). The portal vein pressure was positively correlated to the plasma level of glucagon in portal venous blood of cirrhosis (r = 0.57, P < 0.01).
  
  
  CONCLUSIONS
  Hyperglucagonemia may be caused by the decreased glucagon metabolism in cirrhotic liver and hypersecretion of pancreas and the gastrointestinal tract. Hyperglucagonemia may be amended after portacaval shunts.
