title: Hyperinsulinaemia increases insulin action in vivo in white adipose tissue but not in muscles.
abstract: The effect of 4 days of stable hyperglycaemia and resulting hyperinsulinaemia on insulin-induced glucose utilization by individual rat tissues was studied in vivo. The treatment produced a net increase in the glucose utilization index under both basal and insulin-stimulated (euglycaemic/hyperinsulinaemic clamp) conditions in white adipose tissue. On the contrary, glucose utilization was unchanged in aerobic muscles but was decreased in glycolytic skeletal muscles during the clamp.
