Diabetes mellitus is a group of syndromes characterized by hyperglycemia, altered metabolism of lipids, carbohydrates and protein and an increased risk of complication of vascular diseases. Type 2 diabetes mellitus is characterized by derangement of insulin secretion and an inability of the peripheral tissues to respond to insulin. In spite of the availability of many animal models for Type 2 diabetes mellitus including genetic and chemically induced, none of them simulate human Type 2 diabetes mellitus. An attempt has been made in the present review, to evaluate the neonatal streptozotocin-induced rat (n-STZ rats) model of Type 2 diabetes mellitus, for its potential advantages as a suitable model over the others. The n-STZ model (with alteration of dose and day of STZ injection) exhibits various stages of Type 2 diabetes mellitus such as impaired glucose tolerance, and mild, moderate and severe glycemia. The cells in n-STZ rats bear a resemblance to insulin secretory characteristics found in patients with Type 2 diabetes mellitus. Thus the n-STZ model can be considered as one of the suitable animal models of Type 2 diabetes mellitus.
