OBJECTIVE
To investigate the effect of aqueous extract of Helicteres angustifolia (AEHA) on rats with ulcerative colitis (UC) and its mechanism.
METHODS
SD rats were randomly divided into 6 groups normal control group, the model group, SASP group and 21.6, 10.8, 5.4 g/kg AEHA group with 10 rats in each group. UC was induced by clyster with 2, 4,6-trinitrobenzesulphonic acid (TN-BS) in rats. Rats were given AEHA by gavage for 3 weeks, and sacrificed at day 22nd to determine the expressions of IL-10, IL-6 and TNF-alpha in blood. Colon tissue pathological changes were investigated.
RESULTS
Compared with the control group, the expression of IL-10 was increased, the expressions of IL-6 and TNF-alpha were decreased in AEHA treatment groups. The colon tissue damages and the symptoms of UC rats were improved.
CONCLUSIONS
AEHA can keep balance of inflammatory factors in blood of UC rats, and improve it's colon tissue damages and symptoms.
