Figure 6From: Kaolin-induced chronic hydrocephalus accelerates amyloid deposition and vascular disease in transgenic rats expressing high levels of human APPDegenerative changes in hydrocephalic rat vessels compared to controls (arrows). (A) Age-matched sham-operated control demonstrating a normal appearing parenchymal vessel. (B) six-month-old tgAPP21 rat at 10 weeks post-kaolin showing very subtle vascular changes. (C) six-month-old tgAPP21 rat six months post hydrocephalus induction demonstrating rather marked vessel wall degenerative changes and expansion of the Virchow-Robin space.
