Following treatment with traditional Chinese medicine or western medicine, β-amyloid expression decreased and neuronal morphology was normal in the rat hippocampal CA1 region, in addition to significantly shortened average latency in the Morris water navigation task. These findings suggested that compound prescription of Buyuan Congnao decoction, similar to the curative effects of piracetam, decreased hippocampal β-amyloid expression in a rat model of Alzheimer＇s disease, as well as improved learning and memory.展开更多

The miRNA were extracted from the condensed ginseng decoction by plant microRNA extraction kit. Then miRNA were treated by DNase I and subjected to agarose gel electrophoresis and Agilent 2100 bioanalysis. Mi R-159 and mi R-6135, which were highly expressed in ginseng, were selected and verified by real-time quantitative PCR to detect the expression in the decoction.Results: Ginseng miRNA were successfully extracted from fresh decoction. Mi R-159 and mi R-6135 were expressed in fresh decoction with lower levels than those of fresh ginseng.Conclusion: miRNAs stably existed after processing, and retained some stability after high-temperature treatment. The findings provide a valuables basis for the further studies on ginseng miRNAs.展开更多
