Objective: To observe the effect of Shenling Baizhu San on the expressions of interleukin (IL)-13
IL-23 and cyclooxygenase-2 (COX-2)
CAMP response element binding protein (CREB) in ulcerative colitis rats with spleen deficiency and dampness
in order to explore its mechanism. Method: Totally 48 SPF Wistar rats were randomly divided into 6 groups: blank group
model group
high
medium and low-dose Shenling Baizhu San groups
and mesalazine group
with 8 rats in each group
half male and half female. Except for blank group
the rats in the other groups were included into the saphenous ulcerative colitis model by the combination of disease and syndrome
including diet
environmental intervention and 2
4-dinitrobenzene sulfonic acid enema. After successful modeling
Shenling Baizhu San group was respectively treated with the drug at high dose
middle dose and low dose (24
12
6 g·kg-1·d-1)
and mesalazine group was treated with the drug (0.2 g·kg-1·d-1) for gavage. After 21 days of treatment
the levels of IL-13 and IL-23 in colonic tissues were detected by enzyme-linked immunosorbent assay (ELISA); mRNA expressions of IL-13
IL-23
COX-2
CREB in colonic tissues were detected by Real-time PCR; the protein expressions of COX-2
CREB in colonic tissues were detected by Western blot. Result: Compared with the blank group
the model group rats' IL-13 content and IL-13 mRNA expression in colon were significantly decreased (P<0.05)
IL-23 content and IL-23 mRNA expression increased (P<0.05)
COX-2
CREB mRNA expression and relative protein expression increased (P<0.05). Compared with the model group
IL-13 and IL-13 mRNA expressions in the colonic group were significantly higher than the rats treated with Shenling Baizhu San (high
medium and low doses)
especially in the high-dose group (P<0.05)
IL-23 content and IL-23 mRNA expression decreased (P<0.05)
and COX-2
CREB mRNA expressions and relative protein expression decreased (P<0.05). Conclusion: Shenling Baizhu San can strengthen spleen Qi and excrete moisture
which may regulate the expressions of IL-13
IL-23 and COX-2
CREB in the colon of rats with spleen deficiency and dampness
