          摘   要  目的  探究加味三黄膏对大鼠肛门溃疡和肿胀的改善作用机制。方法  利用冰醋酸建立大鼠肛门溃疡模型,考察加味三
          黄膏低、中、高剂量组(185、370、740 mg/kg)和西药阳性对照组(复方角菜酸酯乳膏,1 g/kg)、中药阳性对照组(马应龙麝香痔疮膏,
          1 g/kg)对模型大鼠体重、肛门溃疡面积和肛门溃疡等级的影响。利用巴豆油建立大鼠直肠肿胀模型,考察加味三黄膏低、中、高剂
          量组(185、370、740 mg/kg)和西药阳性对照组(复方角菜酸酯乳膏,1 g/kg)、中药阳性对照组(马应龙麝香痔疮膏,1 g/kg)对模型大
          鼠直肠肛门肿胀率、血清中炎症因子[白细胞介素2(IL-2)、IL-4、肿瘤坏死因子α(TNF-α)]含量、直肠组织病理形态、直肠组织中瞬
          时受体电位通道V1(TRPV1)和P物质表达以及直肠血管通透性的影响。结果  加味三黄膏各剂量均可不同程度升高肛门溃疡模
          型大鼠体重增加量,减少肛门溃疡面积,降低肛门溃疡等级;其能改善直肠肿胀模型大鼠的直肠组织损伤,降低直肠肛门肿胀率和
          血清中炎症因子含量、直肠组织中TRPV1和P物质表达以及直肠血管通透性(P<0.05或P<0.01),其效果优于西药阳性对照、中
          药阳性对照。结论  加味三黄膏可通过降低炎症因子释放、抑制TRPV1及P物质表达来改善大鼠肛门溃疡和肿胀。

          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
