Methods: The experimental type Ⅱ diabetic rats were induced by injection of strepiozotocin (STZ, 30mg/kg ) and fed with high fat and high glucose fond. The rats were divided into three groups: a normal conrmal control group, a diabetes group and a treated group. The treated group were hypodermically injected insulin 3U/d at interfemus for 4 months, white DC and NC group were vehicle groups that were treated with the same close saline, By using SABC method, thee express ion of collagen type Ⅰ and Ⅲ in SAN was detected.
