参藿口服液药理作用的初步研究

目的 :利用小鼠研究参藿口服液的初步药理作用。方法 :游泳、避暗、自主活动度和睡眠实验。结果 :参藿口服浓缩液 5～10mL·kg^-1连续口服给药 7d ,能明显延长小鼠负重游泳时间 ,增加小鼠耐缺氧生存时间 ,对剥夺睡眠小鼠所引起的学习记忆障碍也有一定的改善作用 ;参藿口服浓缩液 5～2 0mL·kg^-1连续口服给药 10d ,可明显增加正常小鼠的自主活动度 ,并能对抗安定所致的镇静作用 ,缩短戊巴比妥钠的睡眠时间。结论 :参藿口服液对小鼠具良好的抗疲劳、抗应激、增强学习记忆等药理作用。

Primary research of pharmacological effects of PEC on mice

OBJECTIVE: To study pharmacological effects of PEC (the oral liquid which consists of Panax quinquefolium, Epimedium brevicornum, Schisandra chinensis Bail and Cervus eplaphus) on mice. METHOD: Experiments were carried out through swimming test, step-through, spontaneous activity and sleeping time. RESULT: When 5-10 mL x kg(-1) of PEC was given orally for 7 days, it could prolong swimming duration of mice in water tank, and increase the tolerant ability against oxygen-deficiency. PEC could also improve cognitive-deficiency induced by taking off sleep with force in mice after given orally for 7 days. The PEC could increase the spontaneous activity in mice, antagonize the inhabitation induced by Valium, and shorten the sleeping time caused by sodium pentobarbital. CONCLUSION: PEC has strong potential neuro-pharmacological activities such as anti-fatigue, improving cognitive-deficiency in mice.
