| Abstract | |
We studied if salt overload leads to an increase in neointima in injured arteries, and evaluate the involvement of the renin-angiotensin in this process. Were used C57Bl6 male mice treated for 2 or 12 weeks with 1% NaCl to drink or water (cont, sal2 sal12 groups) submitted to vascular injury. The group sal12 increased vascular injury and altered the relationship of collagen fibers, with exacerbation of collagen deposition in the vascular injury, and the relationship between vascular angiotensin II and (1-7), with an increase of Ang (1-7) and no reduction of Ang II after injury. The results indicate that salt overload increases neointima in injured arteries, and modifies the relationship between angiotensin II and (1-7), possibly providing the increase in intima/media ratio observed.
