摘要: 目的 观察石杉碱甲透皮控释贴片(Hup-ATDDS)督脉穴位给药对东莨菪碱(Scop)致小鼠学习记忆障碍的影响,比较穴位给药与一般部位给药的作用差异,探讨督脉穴位给药机理,为穴位透皮控释给药新途径提供初步实验依据。方法 采用跳台、“Y”迷宫等行为药理学实验方法,观察Hup-A TDDS穴位给药与一般部位给药对Scop 小鼠记忆障碍的改善作用,并以小鼠脑胆碱酯酶活性等指标初步探讨穴位给药的作用机理。结果 跳台试验和电迷宫试验表明,Hup-A TDDS 督脉百会穴用药后3 ~ 6 h间有明显的改善学习记忆作用:13.4 μg/0.25cm2 组用药后4h 为佳,5~6 h 时作用减弱;26.7μg/0.25cm2 组自药后3 h 起作用明显,药后4 h 作用最为显著,维持至6h 仍有良好作用;Hup-A TDDS 26.7 μg/0.25cm2 经百会、哑门、大椎、至阳和命门五个穴位给药均有明显的改善学习记忆作用,其中以百会穴组的作用最为显著;Hup-A TDDS 经百会穴或一般部位(选臀位)给药均有改善学习记忆作用,但以百会穴给药较臀位用药作用更为显著,且Hup-A TDDS26.7 μg/0.25cm2 组对小鼠脑胆碱酯酶活性有明显抑制作用。结论 Hup-A TDDS 督脉穴位给药的改善记忆作用优于一般部位给药;其改善学习记忆作用可能是由于抑制脑CHE 活性,改善胆碱能系统功能所致。

Abstract: AIM: To observe the improvement function of huperzine-A transdermal drug delivery system(Hup-A TDDS)administration at Governor Vessel(GV)acu-points on memory disorders induced by scopolamine in mice and to compare the effect of GV acu-points administration with general place administration.METHODS: Stepdown test and “Y” maze test were used to observe the influence of Hup-A TDDS administration at GV acu-points on memory disorders induced by scopolamine.Some biochemical indices were also etermined.RESULTS: (1)The marked effects were found among 3 -6 h after Hup-A TDDS administration at GV baihui acupoint.The best effects showed 4 h after administration,and it weakened a little from 5 h to 6 h in 3.4 μg/0.25cm2 group.At 26.7 μg/0.25 cm2 group,the drug action maintained an effective level from 3 h to 6 h,and reached the maximum at 4 h.(2)Among 5 acu-points of GV to administration at Hup-A TDDS 26.7μg/0.25cm2,the obvious effects on memory disorders existed,and baihui(GV20)was the most effective acu-point.(3)The administration of Hup-A TDDS(26.7μg/0.25cm2 and13.4 μg/0.25cm2)through both acu-point and general place(buttocks),approved memory improvement function by stepdown test and “Y” maze test,and the action in baihui acu-point groupshowed more significant.The depressed trend of cholinesterase activity in brain was proved in all of both GV acu-point and general place groups and baihui acr-point groupexposed signal difference when compared with mokcl group.CONCLUSION: Hup-A TDDS administration at GV acu-point shows a better improvement of memory disorders in comparison with general place.The action mechanism may be due to the depressed cholinesterase activity and the improved cholinergic system function.
