Altered lysosomal glycohydrolase activities in juvenile diabetes mellitus.

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...
