Case analysis Type II diabetes rat model
Type II diabetes is increasing in prevalence worldwide, and it is strongly associated with obesity and insulin resistance, as well as defects in pancreatic β-cell function and mass. Although the broad outlines of the disease etiology are known, many critical questions remain to be answered. In order to further elucidate the pathobiology of this disease, animal models mimicking the pathology of human type 2 diabetes are of great value.

Caracteristics
Compared with the control group, blood glucose increased, serum triglycerides (TG), cholesterol (TC), low-density lipoprotein (ldl-c), high-density lipoprotein (hdl-c), free fatty acid (FFA), glycosylated hemoglobin (HbA1c) increased, and insulin decreased significantly.The pancreatic and renal tissues showed different degrees of pathological changes.
