in order to assess the adrenergic contribution to hypoglycemic glucose counterregulation in type i diabetes mellitus and to determine whether the adrenergic contribution is mediated through beta 1- or beta 2-adrenergic receptors , hypoglycemia was induced by an i.v . insulin infusion ( 30 mu/m2 x min ) for 60 min in 11 insulin-dependent diabetic patients ( iddm ) , 5 with normal plasma glucagon responses and 6 with blunted responses , and also in 7 age-weight-matched nondiabetic subjects .
