Objective To investigate the effect of blood glucose instability on respiratory burst of leukocytes in patients with type 2 diabetes(T2DM). Methods Forty-five patients with T2DM were divided into 3 groups after continuous glucose monitoring for 72 h with glucose wavy coefficient <1.5(n=11), between 1.5 and 3.0(n=19), and >3.0(n=15). Peripheral blood neutrophils were isolated from the diabetic patients and normal control subjects for assay of glucose 6-phosphate dehydrogenase(G6PD) with a spectrophotometric ...
