[Plasma insulin, C-peptide and glucose concentrations in type I diabetic children after a morning injection of insulin (author's transl)].

Plasma levels of insulin, C-peptide and glucose were monitored for 24 hours after a single injection of a mixture of regular and protamine zinc insulin in 22 diabetic children. Results were compared with those in 7 control children. They indicate that plasma insulin in diabetic children is similar or higher than that in controls over the entire time of survey.
