Protective effects of cultured and fermented ginseng extracts against scopolamine-induced memory loss in a mouse model


This study was performed to investigate the effect of a concentrate of fermented wild ginseng root culture (HLJC0701) on memory improvement in the scopolamine (SPL)-induced memory-deficient mouse model. Eight-week-old male ICR mice were used to evaluate the protective effect of HLJC0701 against the SPL-induced memory loss animal model. The Morris water maze test, which measures hippocampus-dependent learning ability, and the Y-maze test, a short-term memory assessment test, were performed and related markers were analyzed. HLJG0701-treated groups displayed significantly reduced acetylcholinesterase activity and increased acetylcholine level compared with the SPL-administered group (SPL-G) (P<0.05). In the Y-maze test, the spontaneous alternation in al HLJC0711-treated groups was significantly increased compared with that in SPL-G (P<0.05). In the Morris water maze test, the escape latency and time spent in the target quadrant in all HLJC0701-treated groups were significantly decreased and increased, respectively, compared with those in SPL-G (P<0.05). In addition, the brain-derived neurotrophic factor level in groups treated with HLJC0701 300 and 600 mg/kg body weight was significantly increased compared with that in SPL-G (P<0.05). These results suggest that the HLJC0701 may protect against memory loss by inhibiting acetylcholinesterase activity and preventing acetylcholine deficiency.
