Brain histopathology. A HE staining and Nissl staining in the hippocampus of the rat between each group. The magnifications and scale bars were shown. B TUNEL staining demonstrated neural cell apoptosis in the hippocampus of the rat after cardiac arrest in each group. C HE staining showed that there were few injured neurons in the hippocampal CA1 area of the rats in the Normal group and the Sham group. Compared with the Normal group and the Sham group, there was a higher percentage of injured neurons in the hippocampal CA1 area of the rats after CA, and the severity was increased with duration of CA time. D The percentage of surviving neurons in the hippocampal CA1 area decreased with the duration of CA. E The percentage of TUNEL-positive neurons in the hippocampal area were increased with the duration of CA. *P < 0.05; **P < 0.01; ***P < 0.001. bar = 50 μm
