Objective: To observe effect of Psoraleae Fructus and Myristicae Semen in Ershen Wan after and before being processed on intestinal flora and expression levels of uncoupling protein 2 (UCP2) mRNA of spleen-kidney Yang deficiency diarrhea rats
to preliminarily explore its possible mechanism. Method: Rat model of spleen-kidney Yang deficiency diarrhea was made through perfusion of adenine
irregular diet and reception of ice Sennae Folium extract.Rats were averagely subdivided into four groups
such as normal group
model group
raw products group and processing group of Ershen Wan.Real-time fluorescence quantitative technique was employed to investigate effect of Ershen Wan on intestinal flora.Expression levels of UCP2 mRNA in renal tissues were assayed by immunohistochemical staining SP method. Result: Intestinal flora and expression levels of UCP2 mRNA of spleen-kidney Yang deficiency diarrhea rats changed obviously by comparing with before modeling;flora of Bifidobacterium longum and Lactobacillus was abnormally low
contents of Escherichia coli and Enterococcus faecalis increased significantly
the expression level of UCP2 mRNA in rat renal tissues of model group was significantly increased.The alteration of intestinal flora and expression levels of UCP2 mRNA recovered after receiving Ershen Wan
and the processing group was the best. Conclusion: Ershen Wan
consisting of salt-fried Psoraleae Fructus and bran-roasted Myristicae Semen
has function of promoting proliferation of intestinal available bacteria
inhibiting intestinal harmful bacteria and down-regulating expression levels of UCP2 mRNA in renal tissues
which may be related to regulation of intestinal flora and the body's basal metabolic rate.
