摘要
Brains of rats that had received needle stab wounds were examined sequentially for 72 h by immunohistochemistry using antibodies to beta-amyloid precursor protein (APP). Immunoreactivity appeared 0.5 h after the injury in axons adjacent to the needle tract, becoming stronger over 15 h in neighboring swollen axons. APP-immunoreactive glial cells appeared 6 h after the injury around the needle tract and persisted throughout the experiment. Morphologically, these cells were thought to be mainly astrocytes.
