Fig. 4From: Limb remote ischemic postconditioning protects cerebral ischemia from injury associated with expression of HIF-1α in ratsQuantitative analysis of HIF-1α positive cells. The analysis of HIF-1α positive cells in cerebral cortex. Compared to sham group, the number of HIF-1α presented a substantial increase in I/R and LRIP group (##p < 0.01) at 3 and 7 days. Compared to I/R group, the positive cells were downregulated in LRIP group at 1 and 3 days (**p < 0.01)Back to article page
