Study of Different Patterns of Immuno-Modulatory Mechanism byTonifying Kidney and Invigorating Spleen Drugs

Objective: To observe the acting pattern on the immune system by Kidney tonifying (KT) drugs. Methods: Three composite recipes were used on the 7- and 14-day corticosterone rat model to study the effect of recipes on the different patterns of immuno-modulatory and neuro- endocrinological systems. Results:The immune system of Spleen Invigorating(SI) group was well protected in either 7- or 14-day experiments,with the SI recipe showing no effect on the neuroendocrine system. It suggested that SI recipe might have direct action on immune system. On the other hand, KT group with no effect on neuroendocrine-immune (NEI) system in 7-day experiment, but showed a remarkable protective effect of the whole NEI system in 14-day experiment. Conclusion: The results indicated that KT recipe acts on the neuroendocrine system first, and then influence the immune system. It means that the action took place through down pathway of NEI network.

补肾和健脾对免疫系统不同作用方式的研究

目的：探讨补肾药对免疫系统的作用方式。方法：用３类复方对皮质酮大鼠分别在７天与１４天实验里，进行对神经内分泌及免疫系统不同作用方式的研究。结果：无论７天或１４天，健脾组的免疫系统均得到保护，而神经内分泌系统却未有明显作用，说明健脾药是对免疫系统的直接作用；补肾组虽７天实验尚未见对各系统有何影响，至１４天实验才显示对神经内分泌免疫系统的全面作用。结论：补肾药是先作用于神经内分泌系统，而后才影响于免疫系统，亦即是作用于神经内分泌免疫网络的下行通路。

淫羊藿总黄酮与补肾复方对皮质酮大鼠T细胞凋亡相关基因群调控的对比研究

目的 :对比淫羊藿总黄酮 (EF)与两个含淫羊藿总黄酮的补肾复方及健脾复方对皮质酮鼠模型T细胞凋亡及其相关基因群的调控作用。方法 :采用TUNEL标记的流式细胞技术及荧光实时定量PCR技术对各组大鼠T细胞凋亡及相关基因群mRNA表达水平进行定量与比较。结果 :EF与两个补肾复方都能够降低T细胞凋亡率 ,并对促凋亡及抗凋亡基因群进行适度地调控 ,而健脾方则不能。结论 :EF对皮质酮大鼠T细胞凋亡及其相关基因的调控作用可以代表补肾复方拮抗外源性激素对T细胞的抑制作用。
