1、2014年第18卷第24期实用临床医药杂志JournalofClinicalMedicineinPractice·7·黄芪注射液对大鼠急性脊髓损伤的神经保护作用张洁妹,唐扣明(上海中山医院青浦分院药剂科,上海,201700)摘要:目的探讨黄芪注射液对急性脊髓损伤大鼠的神经保护作用及其机制。方法将40只成年健康sD大鼠随机分为4组,每纽1O只。采用改良ALLEN氏重物打击法建立脊髓损伤大鼠模型。A组给予黄芪注射液2mL/(kg·d),连续给药14d。B组给予黄芪注射液0.5mE/(kg·d),连续给药14
2、d。C组术后立即腹腔注射甲基强的松30mg/kg,24h内每隔4h后重复给药1次。D组给予灭菌生理用水0.5mL/(kg·d)连续14d。各组用药后1、5、1O、14d分别进行Rivlin斜板实验对大鼠脊髓功能的行为学评分进行评价,采用改良Gale联合行为评分(CBS)测定大鼠脊髓损伤后的神经学方面功能,在给药后48h测定脊髓损伤组织的重量,并根据公式计算脊髓损伤组织的含水量。结果A组各时间点Rivlin斜板度数明显高于B组和D组,差异有统计学意义(P<0.05);A组效果明显优于D组和B组。与D组相比
3、,A组大鼠损伤脊髓的神经功能得到改善,CBS明显提高。根据公式计算脊髓损伤组织的含水量,D组和B组的含水量明显高于A组,而A组和c组的差异无统计学意义。结论高剂量黄芪注射液能够改善大鼠损伤脊髓的神经功能,降低脊髓损伤组织的含水量,从而减轻组织的水肿。关键词:黄芪注射液;甲基强的松;急性脊髓损伤;神经功能中图分类号:R322.81文献标志码:A文章编号:1672~353(2014)24-007-04DOI:10.7619/jcmp.201424003Neur0pr0tectiVefunctionofast
