Eight maturity-onset diabetic patients who had no infections, liver diseases or other endocrine diseases which might affect carbohydrate metabolism were treated with monocomponent lente insulin, which is known to have little antigenicity, until blood sugar was controlled. The diurnal values of the blood sugar (BS) and immunoreactive insulin (IRI) were obtained before treatment and on the third day after the withdrawal of insulin treatment. One patient was dropped from the study because of insulin antibody formation. The total integrated IRI area in the diurnal profile was increased from 98.9±23.7 to 186.1±37.7μU·h/m<I>l</I> (p<0.05), while the total blood sugar area was decreased from 7, 500±1, 200 to 5, 510±1, 214mg·h%(p<0.05). Oral Glucose Tolerance Test on the fourth day after the withdrawal of insulin treatment showed increased IRI response compared to pretreatment.<BR>It is concluded that endogenous insulin secretion could be increased in the diabetic patient by the metabolic control with exogenous insulin injections.
