Spinal cord injury is nowadays still a challenging disease, and a treatment option aimed at the primary site of injury does not currently exist. Therefore, the management of acute spinal cord injury has recently focused on the reasons behind the aggravation of the initial insult through secondary mechanisms, and the search for pharmacological treatment protocols is generally aimed at reducing and minimizing the neural injury and neurological sequela. The secondary spinal cord injury usually develops following a primary lesion induced by spinal cord contusion and the emergence of apoptotic cells has been found to play an important role in the development of secondary injury. We propose that huperzine A may induce a significant reduction in the number of apoptotic cells because it possesses the ability to protect cells against glutamate, ischemia and staurosporine-induced cytotocity and apoptosis. ⋯ When compared with controls, huperzine A treatment demonstrates a significant reduction in the number of apoptotic cells. In addition, the group treated with huperzine A showed significant and appreciable neurological improvement in rats.
