| 1 | Prevention effect of medical self-crosslinking sodium hyaluronate gel on epidural scar adhesion after laminectomy显示文摘Objective:To analyze the effect and medical sclf-crosslinking sodium hyaluronate gel on epidural scar adhesion after laminectomy.Methods:A total of 24 New Zealand L5 laminectomy rabbits were randomly divided into four groups,group A as the control group without any treatment:group B covered by sodium hyaluronate gel;group C and group D covered by 0.5 and1.0 mL medical self-crosslinking sodium hyaluronate gel.All rabbits were scored at various time points after 2.4,6,8,12 weeks,then the formation of scar was observed.Results:In Groups B,C,D loose scar tissue occurred after 2 weeks of the operation,scar tissues were significantly less than that in group A,with mild inflammatory reaction.After 8 weeks,the scar tissues of group B were significantly more than that of groups C,D.After two weeks,group B,C were back to the preoperative level;After 4 weeks,group D was back to the preoperative level;After four weeks,the CSEP of group A was increased significantly,which was significantly higher than that in groups B,C,D.The motor function score of group A,group B and group C were the same as preoperative,but that in group D it was decreased significantly,and then it gradually recovered.After 4 weeks it kept a stable level.The motor function score of group A was decreased gradually after the operation,which kept a stable level after 4 weeks,the motor function score was significantly lower man that in groups B,C,D.Conclusions:Determination of somatosensory evoked potentials is sensitive indicator of spinal cord injury;Application of medical selfcrosslinking sodium hyaluronate gel is effective on epidural scar adhesion after laminectomy. | Hua Liu Hai-Feng Li Jian-Yuan Wang | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，6： | 3 |
