EXPERIMENTAL STUDY OF L-NNA FOR TREATING ACUTE SPINAL CORD INJURY OF RATS / 解剖学报

ABSTRACT

Objective To observe the changes of behaviour, NOS neurons, Nissl bodies and ultrastructure after L-NNA treatment of acute spinal cord injury in rats. Methods Using movement and incline plane(IP)score to observe hindlimbs movement of rats with spinal cord injury; NADPHd histochemistry, Nissl methed and electron microscopy were used for observation of changes of neuronal NOS, Nissl bodies and ultrastructure of three groups(normal control group, saline solution(NS)control group and L-NNA group). Re- sults 1. Changes of behaviour Hindlimbs movement and IP score in L-NNA group is more potent than that in NS group(P
