β¦ Synopsis
Alloxan-induced diabetes in rats significantly impaired the capacity of the erythrocytes to metabolise glucose in vitro to either lactic acid or CO2. Both these metabolic activities were initially insensitive to insulin in normal as well as in diabetic animals; but became responsive when these cells were subjected to insulin and glucose 'starvation' for 1 h through incubation in their absence. This action of insulin in starved cells showed concentration dependence and required preincubation with the hormone prior to addition of glucose.

A B-cell-deficient model for Type 2 (non-insulindependent) diabetes mellitus has been investigated with regard to insulin action at the cellular level. Two-day-old male Sprague Dawley rats were injected with streptozotocin (90 mg/kg) or citrate buffer. At 6 weeks streptozotocin-treated animals were
Insulin secretion and islet glucose metabolism were compared in pancreatic islets isolated from GK/Wistar (GK) rats with spontaneous Type 2 (non-insulin-dependent) diabetes mellitus and control Wistar rats. Islet insulin content was 24.5 +/- 3.1 microU/ng islet DNA in GK rats and 28.8 +/- 2.5 microU
