Abstract | BACKGROUND/AIMS: Acute hemorrhage results in hyperglycemia regulated in a redundant manner by adrenal catecholamines and hepatic sympathetic nerves. In addition, insulin secretion is suppressed and insulin resistance is accounted for completely by elimination of the hepatic insulin-sensitizing substance (HISS) component of insulin action. Blockade of HISS action secondary to blood loss leads to a state known as HISS-dependent insulin resistance (HDIR) which results in a decrease in the glucose disposal action of insulin by 33 +/- 3%. METHODS: RESULTS: CONCLUSIONS: The adrenergic system is not involved in producing HDIR in response to hemorrhage. Somatostatin appears to be the hormonal regulator of this response and it is suggested that the somatostatin derives from a neural origin within the liver.
