ABSTRACT
Objective To evaluate the effects of Guhong Injection on motor dysfunction in rats after cerebral ischemia-reperfusion. Methods The middle cerebral arteries were occluded for 2 hours and re-perfused in Sprague-Dawley rats. They were divided in sham group, model group, Aceglutamide group, Safflowere group and Guhong group, which were intravenously administrated with normal saline, Ace-glutamide, Safflower or Guhong 24 hours after operation, and continued for 14 days. They were tested with the beam-walking test after treat-ment. Tyrosine hydroxylase (TH) immunohistochemical staining was used to investigate the viability of neurons in the substantia nigra. Re-sults The model group spent more time in the beam-walking test than that in the sham group (P<0.01), and it decreased in the Safflower group and Guhong group compared with that in the model group (P<0.05). The TH-positive neurons decreased in the model rat compared with that in the sham group (P<0.001), and increased in both Safflower and Guhong groups compared with that in the model group (P<0.01). Conclusion Guhong administration could significantly improve the motor dysfunction in rats after cerebral ischemia-reperfusion, which might be related to provent the neurons from injury in the substantia nigra.
