[Comparison of blood glucose and insulin concentrations in man after intravenous injection of 1.0, 0.1 and 0.01 mg of glucagon (author's transl)].
The effect of various doses of glucagon on hyperglycemic action and insulin secretion was studied in 12 healthy volunteers to determine whether 1.0 mg of glucagon, the usual dose, is indeed necessary to obtain an adequate hyperglycemic response. For this purpose 2.0, 1.0, 0.5, 0.1 and 0.01 mg of glucagon (Novo) were used respectively to confirm the existence of a dose response relationship. Of these doses, three different doses were administered to one subject within a week after overnight fasting. Maximum increment of blood glucose was not statistically significant between 1.0 (32.5+/-4.4mg/dl) and 0.01 mg (29.5+/-2.7 mg/dl), averaging about 30 mg/dl. The peak time of blood glucose concentration was 30 min. with 1.0 mg, and 10 min. with 0.01 mg. On the contrary, insulin secretion after glucagon injection decerased as the dose decreased. Maximum blood insulin (IRI) concentration was 69.7+/-17.2muu/ml with 1.0 mg, and 25.3+/-11.3 muu/ml with 0.0l mg (p less than 0.05). The peak time of insulin concentration was 2 min. with 1.0 mg, and 10 min. with 0.01 mg. From these data it is concluded that the dose response relationship after intravenous glucagon injection of between 1.0 mg and 0.01 mg doses exist concerning insulin sercretion, but not concerning hyperglycemic response.
