After four-weeks of AAP treatment, (A) blood glucose levels and (B) AUC of OGTT in experimental rats were detected. Data are expressed as the mean + standard error (n=12). #P<0.05, ##P<0.01 vs. CT; *P<0.05, **P<0.01 vs. DM rats. AAP, Auricularia auricular polysaccharide; AUC, area under the curve; CT, control group; DH, metformin group; DM, diabetic model group; HFHSD, high-fat high sucrose diet; Met, metformin; STZ, streptozotocin.
