摘要: |
目的探讨黄芪总苷(AST)和三七总皂苷(PNS)对脑缺血再灌注小鼠能量代谢障碍的影响。方法C57BL/
6 小鼠被随机分成假手术组、模型组、AST 组(110 mg/(kg·d),ig),PNS 组(115 mg/(kg·d),ig),AST+PNS 配伍组(AST
110 mg/(kg·d)+PNS 115 mg/(kg·d),ig)和依达拉奉组(8 mg/(kg·d),ip),分别给药,连用4 d。在最后1 次给药1 h 后
制作脑缺血再灌注损伤模型,检测脑组织三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、一磷酸腺苷(AMP)含量和Na+-K+-
ATPase 酶活性。结果AST 和PNS 配伍对脑缺血再灌注后ATP、ADP 含量、总腺苷酸池(TAN)值和ATP 酶活性的降
低具有协同抑制作用,差异具有统计学意义(P<0.01),对能荷(EC)值的减少具有相加的抑制作用(P<0.05)。结论
AST 和PNS 配伍可以明显改善脑缺血在灌注后能量代谢障碍, 其作用机制可能与AST 和PNS 能协同提高脑组织能
量的利用和生成,改善能荷、增强Na+-K+-ATPase 的活性有关。 |

Abstract: |
Objective To investigate the effects of Astragalosides(AST) and Panax notoginseng
saponins (PNS) combination on energy metabolism disturbance after cerebral ischemia -reperfusion
in mice. Methods C57BL/6 mice were randomly divided into 6 groups as follows: sham-operated
group,model group,Astragalosides group(AST,110 mg/kg·d,ig),Panax notoginseng saponins group
(PNS,115 mg/kg·d,ig) ,AST combined with PNS group (AST 110 mg/kg·d+PNS 115 mg/kg·d,ig)
and 3-methyl-1-phenyl-2-pyrazoline-5-one group (edaravone,8 mg/kg·d,ip). All mice were administered
respectively and lasted for 4 d. After the last treatment for 1 h,cerebral ischemia-reperfusion
injury model was established. Then, the contents of adenylate(ATP,ADP,AMP) in brain tissues
were measured and the activities of Na+-K+-ATPase were evaluated. Results AST combined with
PNS exhibited synergistic inhibition effects on the decrease of ATP and ADP contents, total ade-nine nucleotides (TAN) and ATPase activities (all P<0.01),and exhibited addition inhibition effects
on the decrease of energy charge (EC) (P <0.05). Conclusion These results suggest that
AST combined with PNS significantly improve cerebral energy metabolism dysfunction after ischemia-
reperfusion. The underlying mechanism may be that AST and PNS synergistically promote
the supply and generation of energy, improve the energy charge, enhance Na+-K+-ATPase activity
in brain tissues. |
