摘要: 目的

探讨栀子苷对帕金森病(PD)大鼠睡眠障碍的影响,阐明其可能的作用机制。

方法

取70只Wistar大鼠,采用6-羟基多巴(6-OHDA)建立PD大鼠模型。造模4周后,腹腔注射阿卟吗啡诱发旋转实验进行模型鉴定,模型构建成功的大鼠分为模型组、低剂量栀子苷组和高剂量栀子苷组,每组10只,另取10只正常大鼠作为正常对照组。低和高剂量栀子苷组大鼠给予栀子苷溶液(50 或100 mg·kg-1 ),正常对照组和模型组大鼠灌胃等量生理盐水。采用脑电图(EEG)和肌电图(GME)记录各组大鼠睡眠时间,高效液相色谱法(HPLC)检测各组大鼠纹状体中多巴胺水平。

结果

与正常对照组比较,模型组大鼠总睡眠时间、慢波睡眠时间和快波睡眠时间均明显缩短(P<0.01),觉醒时间明显延长(P<0.05);与模型组比较,低和高剂量栀子苷组大鼠总睡眠时间、慢波睡眠时间及快波睡眠时间延长(P<0.05),觉醒时间明显缩短(P<0.05);与模型组比较,低和高剂量栀子苷组大鼠纹状体中多巴胺水平明显升高(P<0.05)。

结论

栀子苷可改善PD模型大鼠的睡眠障碍,其机制可能与提高纹状体中多巴胺水平有关。

Abstract: Objective

To discuss the effect of gardenoside on the sleep disorder in the Parkinson’s disease (PD) rats,and to explore its possible mechanism.

Methods

Seventy Wistar rats were selected and 6-hydroxydopa(6-OHDA) was used to establish the PD rat models. After 4 weeks, the PD models were identified by rotation test induced by intraperitoneal injection of apomorphine.After the models were successfully constructed, the PD model rats were divided into model group, low dose of gardenoside group and high dose of gardenoside group, and there were 10 rats in each group;another 10 normal rats were used as normal control group.The rats in low and high doses of geniposide groups were given geniposide solution (50 and 100 mg ? kg-1) by gavage every day. The rats in normal control group and model group were given the same amount of normal saline for 4 weeks.The sleep time of the rats in various groups was recorded using embedded electroencephalogram(EEG)and electromyography(EMG) electrodes,and the levels of dopamine in striatum of the rats in various groups were analyzed by high performance liquid chromatography (HPLC).

Results

Compared with normal control group, the total sleep time, slow wave sleep time and fast wave sleep time of the rats in model group were significantly shortened (P<0.01), and the awaken time was significantly prolonged (P<0.05).Compared with model group, the total sleep time,slow wave sleep time and fast wave sleep time of the rats in low and high doses of gardenoside groups were significantly prolonged (P<0.05), while the awaken time was significantly shortened (P<0.05). Compared with model group, the levels of dopamine in striatum of the rats in low and high doses of gardenoside groups were significantly increased (P<0.05).

Conclusion

Gardenoside can improve the sleep distorder in the PD model rats, and its mechanism may be related to increasing the level of dopamine in striatum.
