On the cover: Representative histological photomicrographs of cross-sections of femoral arteries (elastic-Verhoeffen-von Gieson staining) at 28 days after the cuff placement. The neointima proliferation was markedly enhanced in Dahl salt-sensitive (DS) rats fed a high-salt diet (A). Potassium supplementation (B) significantly reduced the neointimal area in cuffed arteries of salt-loaded DS rats. Original magnification, ×200. Bar=100 μm. Arrows point to the internal elastic lamina. (See page 228.)
