Figure 6From: Magnetic resonance imaging indicators of blood-brain barrier and brain water changes in young rats with kaolin-induced hydrocephalusCaveolin-1 immunoreactivity in hydrocephalic rat brain. Upper panel shows base of control rat brain with strong immunoreactivity (brown) in surface arteries and arachnoid, as well as in penetrating arteries (arrow) and weaker immunoreactivity in veins (arrowhead). Bottom panel shows periventricular white matter (right) and deep cortex (left) of hydrocephalic rat brain 3 weeks after kaolin injection. Strong immunoreactivity is present in a cortical vein (arrow) and moderate to weak immunoreactivity in capillaries (arrowheads). Bar = 200 μm for top panel and 50 μm for bottom panel.Back to article page
