Chronic hypoglycemia and diabetes impair counterregulation induced by localized 2-deoxy-glucose perfusion of the ventromedial hypothalamus in rats.

abstract：:Prolonged near-physiological pulsatile insulin infusion has a greater hypoglycemic effect than continuous insulin infusion. We have previously shown that continuous hyperinsulinemia induces insulin insensitivity. This study examines the mechanisms responsible for the greater hypoglycemic effect of pulsatile insulin ad...
