Treatment ID:	TR002504
Treatment Summary:	Male Sprague Dawley rats were housed in groups of three rats per cage in a temperature-controlled environment, with a 12 h light/dark cycle and ad libitum access to food and water. Experimental diabetes was induced in six week old male Sprague Dawley rats (200-250 g, n = 35) by i.v. injection of streptozotocin (55 mg/kg, sodium citrate buffer pH 4.5) following an overnight fast, as previously described (79). One group of rats received citrate buffer vehicle (0.42% in sterile saline, pH 4.5) as a non-diabetic control with normal blood glucose (NG) (n = 16). One week following STZ treatment, diabetic rats were further assigned to two groups: standard insulin therapy (n = 17 rats), resulting in severe hyperglycemia (SHG) and intensive insulin therapy (n = 19 rats), resulting in moderate hyperglycemia (MHG) using a single daily insulin injection (long-lasting Humulin NPH; Eli Lilly, Indianapolis, USA) to titrate blood glucose levels to >28 mM (1-2 units, s.c. per day) and ∼20 mM (6-7 units, s.c. per day) as required, respectively.
