Monosialoganglioside GM1 (GM1) has been found to alleviate genetic and lesion-induced memory deficits. The purpose of this study was to investigate the effects of 7-day treatment with GM1 (50 mg/kg IP) on acquisition and retention performance of senescent rats in a passive avoidance situation. Saline-treated old rats showed a decreased performance in acquisition and retention tests as compared to saline-treated adult rats. GM1 improved both acquisition and retention performance of old animals, and there was no significant difference between GM1-treated old rats and saline-treated adult rats. These data suggest that GM1 treatment can improve memory deficits in intact senescent animals.
单唾液酸神经节苷脂GM1(GM1)已被发现可减轻遗传性和损伤性诱导的记忆缺陷。本研究的目的是调查GM1(50mg/kg腹腔注射)连续7天治疗对衰老大鼠在被动回避情境中获得和保持能力的影响。与生理盐水处理的成年大鼠相比,生理盐水处理的老年大鼠在获得和保持测试中的表现下降。GM1改善了老年动物的获得和保持能力,并且GM1处理的老年大鼠与生理盐水处理的成年大鼠之间没有显著差异。这些数据表明,GM1治疗可改善未受损衰老动物的记忆缺陷。
