degeneration of (a) hippocampal CA1 pyramidal cells and dentate hilar neurons induced by
cerebral ischemia and (b) CA3 pyramidal cells and dentate hilar neurons induced by
intraventricular injections of kainic acid (KA). The microglial reactions to ischemia, as
monitored by histochemical staining for the enzyme nucleoside diphospatase (NDPase) and
immunohistochemical staining for the complement type 3 receptor (CR3), could be divided …
