ABSTRACT OBJECTIVE To explore the improvement mechanism of Modified sanhuang ointment on anal ulcers and swelling
model rats. METHODS The anal ulcer model of the rat was induced by using glacial acetic acid; the effects of Modified sanhuang
ointment low-dose, medium-dose and high-dose groups (185, 370, 740 mg/kg), western medicine positive control group
(Compound carraghenates cream, 1 g/kg) and TCM positive control group (Mayinglong shexiang zhichuang ointments, 1 g/kg) on
body weight, area of anal ulcer, grade of anal ulcer were investigated. The other groups of rats were used to induce rectal swelling
models with croton oil; the effects of Modified sanhuang ointment low-dose, medium-dose and high-dose groups (185, 370, 740
mg/kg), western medicine positive control group (Compound carraghenates cream, 1 g/kg) and TCM positive control group
(Mayinglong shexiang zhichuang ointments, 1 g/kg) on the rate of rectal and anal swelling, serum contents of inflammatory factors
[interleukin 2 (IL-2), IL-4, tumor necrosis factor (TNF-α)], pathological morphology of rectal tissue, the expression of transient
receptor potential channel V1 (TRPV1) and substance P in rectal tissue and rectal vascular permeability were investigated.
RESULTS In Modified sanhuang ointment, the increase in body weight was enhanced, and the area of anal ulcers, as well as the
grade of anal ulcers in rats with anal ulcer models, were reduced to varying degrees; rectal tissue damage in rectal swelling model
rats was improved; the rate of rectal and anal swelling, the serum contents of inflammatory factors, the expressions of TRPV1 and
substance P in rectal tissue, and rectal vascular permeability were all decreased (P<0.05 or P<0.01). The effect of Modified
sanhuang ointment was better than that of western medicine
