Methods:All the 40 Winstar rats were divided into four groups:group A:the rats were fed with normal diet, group B:the rats were fed with only high|cholesterol diet(no vitamin D3), group C:the rats were treated with one intramuscularly injection of vitamin D3(300000 U/kg) and were denudated of endothelium, followed by high|cholesterol diet, group D:the rats were treated with 5% chitosan added into the diet besides treatment as group C. Ninety days later, the formation of atherosclerosis plaques and the activities of nitric oxide synthase in aortas in the four group rats were investigated.
