Spinal cord morphology research of nursing intervention on motor function repair after spinal cord injury in rats / 局解手术学杂志

ABSTRACT

Objective To explore the morphology changes of spinal cord after nursing intervention on motor function repair spinal cord injuried rats. Methods 60 adult SD rats were randomly divided into normal control group, experimental control group, and experimental group ( n=20 for each group) . Each group were divided into four time phase points, that is 1 day, 7 days, 30 days and 60 days after spinal cord injury (n=5). The model of L4 plane with full transection of spinal cord were made in the rats in experimental control group and exper-imental group. Normal control group were of untreated normal rats, experimental control group were given routine nursing such as urination and defecation after spinal cord injury, and experimental group were given passive movement practices and muscle massage training twice a day (10 min each time) besides regular nursing. HE staining and immunohistochemistry method were applied to observe the morphology changes of spinal cord. Results In experimental control group and experimental group there was no significant changes in HE staning and NF-200 and GFAP immunohistchemistry staning in spinal cord section of rat at each time phase points, but compared to the normal control group, it was of significant difference. Conclusion There is no apparent change in morphology in injured spinal area after nursing intervention.
