查询词典 hippocampal

Results In blank group, the hippocampal structure was clearly viewed, dense neurons with plenty cytoplasm and deep-dyed big nucleolus were observed. Neurons were lining up in order with clear border in CA3 region In model group, hippocampal structure was blurred. The number of neurons decreased greatly, and cells were lining up; rregularly with unclear border. In drug group, the hippocampal structure was clear with more neurons than model group. Neurons had plenty cytoplasm and deep-dyed big nucleolus. Cells were lining up in order with clear border.
