Abstract:
Objective: Pervious RT-PCR results revealed the possibility of effective regulation channel of Xiaoyao San in treating rats of syndrome of liver invading the spleen. This experiment was designed to explore CIS rats’ immunohistochemistry findings in hippocampal subregion CA1 and amygdaloid subregion BLA after suppressing both amygdaloid AMPA receptors by microinjection of CNQX. To compare Xiaoyao San group with CNQX group, and to analysis of these findings may prove the possibility of effective regulation channel of Xiaoyao san treating this syndrome. Methods: 75 male SD rats were randomly divided into 5 equal groups: normal group, CIS group, sham-operation group, CNQX group and Xiaoyao San group. The number of GluR2 positive cells in hippocampal subregion CA1 and amygdaloid subregion BLA in these 5 groups were examined by immunohistochemistry test. Results: Compared with control group, the number of GluR2 positive cells decreased in hippocampal subregion CA1. Statistical analysis showed that no difference existed in control, CNQX and Xiaoyao San groups in CA1 region. Except CNQX group, tendency of changes were contradictory in BLA and CA1 region. In addition, the least in BLA in CNQX group. This finding revealed that Xiaoyao San may act the same as CNQX, thus Xiaoyao San afforded effective protection against this depression syndrome through suppression of both amygdaloid excitability. Conclusion: The balance coordination between hippocampus and amygdala may be the key in transformation from adaption to damage in a state of stress, was one of the central mechanisms of liver governing smoothing qi flow (LGSQF) on regulating the stress. Xiaoyao San may effectively regulate the balance of the excitability of hippocampus and amygdala. This hypothesis may reveal the regulation channel on Xiaoyao San affording effective protection against liver invading the spleen syndrome.
