[The protective effect of exenatide on the renal injury in diabetic rats].

Objective: To investigate the protective effect of exenatide (Ex) on the renal injury in streptozotocin-induced diabetic rats.

Methods: Sprague-Dawley rats were randomly divided into 2 groups:normal control group (NC group, =8) and model group. Model group was injected with low dose of streptozotocin (30 mg·kg) after the rats were fed with high fat and high glucose diet for 4 weeks.
