Abstract:
Aim To investigate the effect of sulfur dioxide (SO2) on blood pressure and aortic structure of the spontaneous hypertensive rat(SHR).Methods Sixteen male SHRs at the age of 4 weeks were randomly divided into SHR control group and SHR+Na2SO3/NaHSO3 group,respectively.Another eight male WKY rats served as WKY control group.Five weeks later, the blood pressure was determined.The rat aortas were dyed with Hart's Method. The morphometric parameters including outer radius, lumen radius and the wall thickness were calculated by Leica workstation. The proliferative index (PI) of smooth muscle cells was detected by immunohistochemical assay.Results The blood pressure of SHR control increased compared with that of WKY control rats(P
