Immunohistochemical analysis of microglial activation and neuronal loss on day 3 post-treatment with UCN. Representative photomicrographs show: (A) low power images of peri-hematomal regions as indicated by squares; (B) high power images stained with OX-42; (C) ED-1; and (D) NeuN. (E) Average cell numbers (OX 42+, ED-1+, and NeuN+) in each plane (total 6 mm2) was calculated from 54 squares in 9 planes. Values are shown as mean ± SD, calculated and analyzed by Student's t test. *p < 0.05 vs. ICH + saline group.
