抗痫增智胶囊对戊四唑点燃大鼠海马苔藓纤维发芽的干预作用

目的:探讨中药抗痫增智胶囊对戊四唑致痫大鼠海马苔藓纤维发芽的干预作用。方法:运用戊四唑点燃法,复制癫痫大鼠模型。实验大鼠随机分为中药高剂量组、中药中剂量组、中药低剂量组、丙戊酸镁组、模型组、正常对照组。造模成功分别灌药28天后应用Timm染色法观察各组大鼠海马苔藓纤维发芽的情况。结果:Timm染色结果显示模型组大鼠海马CA3始层及齿状回分子层苔藓纤维发芽明显增多,其单位面积的密度百分比显著高于正常对照组(P<0.05)。抗痫增智胶囊高、中剂量组的发芽密度百分比低于模型组(P<0.05),但仍高于正常对照组(P<0.05)。结论:抗痫增智胶囊对海马CA3区及齿状回苔藓纤维发芽有较强的干预作用。

Interference effect of Kangxianzengzhi capsule on hippocampal mossy fiber sprouting in epileptic rat kindled by pentylenetetrazol

To explore the interference effect of Kangxianzengzhi(KXZZ) capsule on hippocampal mossy fiber sprouting in epileptic rat kindled by pentylenetetrazol.Methods: Epileptic rat models were established by pentylenetetrazol(PTZ) kindling method.All rats were divided into six groups: KXZZ high-does group,KXZZ middle-does group,KXZZ low-does group,valproate magnesium group, model group and normal group randomly.Then the hippocampal mossy fiber sprouting was monitored by Timm stain method.Results: Mossy fiber sprouting was obvious in the hippocampal CA3 section and the molecular layer of dentate syrus in model group.Compared with normal group,the percent of sprouting density in model group was higher(P<0.05).In KXZZ middle and high dose groups,the percent was much lower than that in model group(P<0.05),but still higher than normal group(P<0.05).Conclusion: KXZZ capsule could efficiently deterred mossy fiber sprouting in hippocampal CA3 section and dentate syrus.
