目的观察柴贝止痫汤及柴胡皂苷a治疗难治性癫痫的可能作用机制。方法 88只大鼠随机分为空白组12只及模型组、卡马西平组、柴贝止痫汤+卡马西平组、柴胡皂苷a+卡马西平组19只。除空白组外
其余各组采用侧脑室注射海人酸制备癫痫大鼠模型。卡马西平组给予卡马西平混悬液0.75 ml/(100 g·d)
柴贝止痫汤+卡马西平组给予柴贝止痫汤0.5 ml/(100 g·d)和卡马西平混悬液0.75 ml/(100 g·d)
柴胡皂苷a+卡马西平组给予柴胡皂苷a混悬液0.25 ml/100 g和卡马西平混悬液0.75 ml/100 g
模型组及空白组给予等量羧甲基纤维素钠混悬液。给药60天后比较各组海马P糖蛋白、Mdr1a mRNA表达及全脑卡马西平(CBZ)、1011-环氧化卡马西平(CBZE)含量。结果与空白组比较
模型组海马P糖蛋白表达升高(P<0.05);与模型组比较
卡马西平组、柴胡皂苷a+卡马西平组海马P糖蛋白表达差异无统计学意义(P>0.05)
柴贝止痫汤+卡马西平组海马P糖蛋白表达降低(P<0.05);与卡马西平组比较
柴贝止痫汤+卡马西平组和柴胡皂苷a+卡马西平组海马P糖蛋白表达均降低(P<0.05)
柴贝止痫汤+卡马西平组和柴胡皂苷a+卡马西平组海马P糖蛋白表达差异无统计学意义(P>0.05)。模型组Mdr1a mRNA表达较空白组升高。卡马西平组的Mdr1a mRNA表达高于空白组(P<0.05)
空白组、模型组MDR1a mRNA表达分别为卡马西平组的0.36倍、0.87倍。柴贝止痫汤+卡马西平组较卡马西平组Mdr1a含量降低(P<0.01)
为卡马西平组的0.14倍。与卡马西平组比较
柴贝止痫汤+卡马西平组CBZE含量升高(P<0.01)
柴胡皂苷a+卡马西平组CBZE含量降低(P<0.01)
且柴贝止痫汤+卡马西平组和柴胡皂苷a+卡马西平组CBZ差异无统计学意义(P>0.05);与柴贝止痫汤+卡马西平组比较
柴胡皂苷a+卡马西平组CBZ、CBZE含量均降低(P<0.01)。结论柴贝止痫汤联合卡马西平可降低癫痫模型大鼠海马Mdr1a/P糖蛋白表达
促进CBZ、CBZE入脑
对CBZE作用突出
柴胡皂苷a在其中不发挥主要作用。
Objective To observe the possible mechanism of Chaibei Zhixian Decoction( CBZXD
柴贝止痫汤)and Saikosaponin a( SSa) in treating intractable epilepsy. Methods A total of 88 rats were randomly divided into blank group of 12 rats and every 19 rats for model group
carbamazepine( CBZE) group
the CBZXD + CBZE group
and the saikosaponin a + CBZE group. Except for the blank group
other groups used the lateral ventricle injection of kainate to prepare a rat model of epilepsy. The CBZE group was given CBZE suspension 0. 75 ml/( 100 g·d). The CBZXD + CBZE group was given CBZXD 0. 5 ml/( 100 g·d) and CBZE suspension 0. 75 ml/( 100 g·d).The saikosaponin a + CBZE group was given saikosaponin a suspension 0. 25 ml/100 g and CBZE suspension0. 75 ml/100 g. The model group and the blank group were given the same amount sodium carboxymethylcellulose suspension. After 60 days of administration
the expression of P-glycoprotein
Mdr1 a mRNA and the content of whole brain carbamazepine( CBZ) and 10 11-epoxidized CBZE were compared. Results Compared with the blank group
the expression of P-glycoprotein in the hippocampus of the model group was increased( P < 0. 05). Compared with the model group
the expression of P-glycoprotein in the hippocampus of the CBZE group
saikosaponin a + carbazepine group was not statistically significant( P > 0. 05). The expression of P-glycoprotein in hippocampus of CBZXD + CBZE group was decreased( P < 0. 05). Compared with CBZE group
the expression of P-glycoprotein in hippocampus of CBZXD + CBZE group and saikosaponin a + CBZE group was decreased( P < 0. 05). There was no significant difference in the expression of P-glycoprotein in hippocampus between CBZXD + CBZE group and saikosaponin a + CBZE group( P > 0. 05). Mdr1 a mRNA expression in the model group was increased compared with that in the blank group. The expression of Mdr1 a mRNA in CBZE group was higher than that in the blank group( P <0. 05). The expression of MDR1 a mRNA in blank group and model group was 0. 36 times and 0. 87 times higher than that in CBZE group. The content of Mdr1 a in the CBZXD + CBZE group was decreased when compared with that in the CBZE group( P < 0. 01)
which was 0. 14 times higher than that in the CBZE group. Compared with CBZE group
CBZE content in CBZXD + CBZE group was increased( P < 0. 01). CBZE content in saikosaponin a +CBZE group was decreased( P < 0. 01)
and there was no significant difference in CBZ between CBZXD + CBZE group and saikosaponin a + CBZE group( P > 0. 05). Compared with CBZXD + CBZE group
saikosaponin a +CBZE group
the content of CBZ
CBZE was reduced( P < 0. 01). Conclusion CBZXD combined with CBZE can reduce the expression of Mdr1 a/P glycoprotein in hippocampus of rats with epilepsy
promote CBZ and CBZE into the brain
and play an important role in CBZE. The saikosaponin a dose not play a major role in the above process.
