项目摘要
We investigated the effects of melanin concentrating hormone (MCH) on sleep-wake cycle. Intraventricular (icv) injection of MCH decreased the waking episode time, whereas it increased the sleep episode time (REM & nonREM episode time). It has been reported that sleep is necessary for consolidation of memory with increasing the hippocampal acetylcholine (ACh). In the present study, icv injection of MCH increased the hippocampal ACh. There was a significant correlation between REM episode time and hippocampal ACh effluxes. Icv injection of MCH did not alter the cortical histamine release. These findings suggest that MCH may contribute to the consolidation of memory. Further experiment is necessary to explore whether the memory function of MCH may be involved in the anesthetic state.
我们研究了黑色素浓缩激素(MCH)对睡眠觉醒周期的影响。脑室室内(ICV)注射MCH会减少醒来的发作时间,而它增加了睡眠发作时间(REM和非REM发作时间)。据报道,与增加海马乙酰胆碱(ACH)合并记忆是必要的睡眠。在本研究中,ICV注射MCH增加了海马ACH。 REM发作时间与海马ACH外排之间存在显着相关性。 ICV注射MCH不会改变皮质组胺释放。这些发现表明MCH可能有助于记忆的巩固。需要进一步的实验来探索MCH的记忆功能是否可能参与麻醉状态。
