Figure 2.

Computer-generated photomicrographs illustrating the basilar artery cross-sectional area examined by light microscopy (toluidine blue staining, ×49). (A) Group 1 (control); (B) group 2 (control plus placebo); (C) group 3 (control plus r-Hu-EPO); (D) group 4 (SAH); (E) group 5 (SAH plus placebo); (F) group 6 (SAH plus r-Hu-EPO). The cross-sectional area of arteries from the SAH-plus-r-Hu-EPO group (group 6) demonstrated a significant improvement of the vasoconstriction compared with groups 4 or 5 (P < 0.05). (Calibration bar, 100 μm.)
