Changes in serum insulin concentrations during hyperglycemic clamp test and malondialdehyde contents and TNF-α mRNA expression in islets. (A). Changes of serum insulin concentration during hyperglycemic clamp procedure. (B). Malondialdehyde contents and TNF-α mRNA expression in islets. Serum insulin concentrations were determined after glucose infusion to achieve a serum glucose concentration of 100 mg/dL above baseline. Dots and error bars represent means ± SDs (n = 10). a,b,c Different letters on bars indicate significant differences (p < 0.05). * indicates a significant intergroup difference (p < 0.05).
