健脾与补肾对脑内神经肽Y水平和基因表达的影响

目的比较健脾与补肾对脑内神经肽(NPY)水平和基因表达的影响。方法采用苦降泻下、饮食失节加劳倦过度法建立脾虚大鼠模型,检测下丘脑腹侧核、海马CA1区、前额叶皮层NPY基因表达变化。结果模型组下丘脑腹侧核、海马CA1区、前额叶皮层NPY免疫阳性反应物明显降低;健脾组与补肾组上述部位的NPY免疫阳性反应物明显增加。模型组下丘脑腹侧核、前额叶皮层NPYmRNA表达明显降低;健脾组与补肾组上述部位的NPYmRNA表达明显增加。结论脾虚模型脑内对学习记忆有促进作用的NPY水平和基因表达有变化,健脾与补肾可能通过调节脑内NPY水平和基因表达而影响学习记忆。

The Influence of Invigorating Spleen and Restoring Virility to the Nerve Peptide Y Level In Brain and Gene Expression

Objective Comparison on the influence of invigorating spleen and restoring virility to the NPY level in brain and gene expression. Method Establishing the spleen insufficiency model of rat by adopting bitter decline diarrhea, wild eating and overworking, to examine the hypothalamus ventral kernel, the hippocampi CA1 area and forehead cortex, the gene expression change of NPY. Result In the model group, the immunoreaction masculine substance of NPY, hypothalamus ventral kernel,hippocampi CA1 area and prefrontal cortex decreases obviously. The immunoreaction masculine substance of NPY on above mentioned parts in the group of invigorating spleen and restoring virility increases distinctly. In the model group, the expression of NPY mRNA on prefronta cortex and hypothalamus ventral kernel decreases obviously, while on the groups of invigorating spleen and restoring virility increases obviously. Conclusion In the model group, the NPY level and gene expression in brain to promote study memory changed. Invigorating spleen and restoring virility may affect study memory by regulating the NPY level and gene expression.
