The study was to investigate the ameliorating effects of three Chinese herbs--Achyranthes bidentata (AB), Ophiopogon japonicus (OJ) and Cnidium monnieri (CM) on scopolamine (SCOP)- and MK-801-induced amnesia by using a passive avoidance task in rats. AB, OJ and CM at 0.1 and 0.3 g/kg prolonged the step-through latency (STL) of the retention trial. In addition, AB, OJ and CM reversed the STL shortened by MK-801, but only AB reversed the STL shortened by SCOP. In conclusion, these Chinese herbs possess cognition-enhancing activities and anti-amnestic effects, but the mechanism of the effect of AB was different from those of OJ and CM.
本研究旨在通过大鼠被动回避任务,探讨三种中药——牛膝(AB)、麦冬(OJ)和蛇床子(CM)对东莨菪碱(SCOP)和MK - 801诱导的记忆缺失的改善作用。0.1 g/kg和0.3 g/kg的AB、OJ和CM可延长记忆保持试验的步下潜伏期(STL)。此外,AB、OJ和CM可逆转MK - 801缩短的STL,但只有AB可逆转SCOP缩短的STL。总之,这些中药具有增强认知和抗记忆缺失作用,但AB的作用机制与OJ和CM不同。
