Figure 6: Insulin release from the pancreas of the different treated rats. Pancreas were perfused with a solution containing 2 g/L bovine serum albumin and 5 mmol/L glucose at the flow rate of 2 mL/min after a 30-min equilibration period. Glucose concentration was changed to 11 mmol/L at 45 min and then changed back to 5 mmol/L at 65 min. Perfusate samples were collected at 30, 40, 45, 46, 47, 48, 49, 50, 55, 60, 65, 70, and 80 min from perfusion beginning, respectively. Data are presented as mean ± SE of ten observations in each group.
