Figure 2

Multiple HBO treatment neither altered the occurrence of hydrocephalus nor affected the ventricular volume after SAH. At 21 days after SAH, 4 rats showed an increased ventricular volume compared with Sham; 6 rats showed no significant difference in ventricular volume. HBO or NBO treatment did not alter the occurrence of hydrocephalus, as 4 rats in each of these groups. Neither HBO nor NBO treatment affected the cerebroventricular volumes in the hydrocephalic animals. Sham, n = 8; SAH w/t HyC, n = 6; SAH/HyC, n = 4; SAH/HyC + HBO, n = 4; SAH/HyC + NBO, n = 4. *p < 0.05 compared with Sham, #p < 0.05 compared with SAH w/t HyC.
