          摘  要  目的  探究化橘红提取物对厌食症模型幼龄大鼠的药效学作用。方法  随机选取10只幼龄大鼠作为对照组给予常规饲
          料,其余50只幼龄大鼠采用病因模拟法建立厌食症模型,将造模成功的幼龄大鼠分成模型组、健胃消食片组(0.65 g/kg)和化橘红
          提取物低剂量(0.5 g/kg)、中剂量(1.0 g/kg)、高剂量(2.0 g/kg)组。连续灌胃给药14 d后,观察各组大鼠体质量及摄食量变化,检测
          胃酸浓度、胃蛋白酶活性,以及血清中胃泌素(GAS)、胃动素(MTL)、抑胃肽(GIP)水平,观察胃组织病理变化情况。结果  与对照
          组比较,模型组幼龄大鼠摄食量、胃酸浓度、胃蛋白酶活性、GAS、MTL水平显著下降,GIP水平显著升高(P<0.05);胃组织病理学
          检查出现明显胃黏膜充血、上皮细胞松解脱落现象。与模型组比较,各给药组经药物干预后,上述指标均有不同程度的改善,胃组
          织病理损伤减轻。结论  化橘红提取物通过调节胃酸浓度、胃蛋白酶活性、GAS、MTL、GIP水平,改善胃动力,保护胃黏膜,从而改
          善幼龄大鼠的厌食症。

          ABSTRACT   OBJECTIVE  To  investigate  the  pharmacodynamic  effects  of  the  Citri  Grandis  Exocarpium  extract  on  anorexia
          model  immature  rats.METHODS  Ten  immature  rats  were  randomly  selected  as  the  control  group  and  given  regular  diet,  while
          anorexia  model  was  induced  in  the  remaining  50  immature  rats  using  the  etiological  simulation  method.  The  immature  model  rats
          were divided into the model group, Jianwei xiaoshi tablet group (0.65 g/kg), Citri Grandis Exocarpium extract low-dose, medium-
          dose  and  high-dose  groups (0.5,  1.0,  2.0  g/kg).  After  14  d  of  continuous  intragastric  administration,  the  body  mass  and  food
          intake of rats in each group were observed, and the gastric acid concentration, pepsinase activity, serum levels of gastrin (GAS),
          motilin (MTL)  and  gastric  inhibitory  peptide (GIP)  were  measured. The  histopathological  changes  in  the  gastric  tissue  were
          observed.RESULTS Compared with control group, the food intake, gastric acid concentration, pepsin activity, the levels of GAS
          and  MTL  were  significantly  decreased  and  GIP  level  was  significantly  increased  in  the  immature  rats  of  model  group (P<0.05);
          gastric histopathological examination showed significant gastric mucosal congestion and loosening and detachment of epithelial cells.
          Compared  with  model  group,  all  administration  groups  showed  different  degrees  of  improvement  in  the  above  indexes  and
          decreased  gastric  histopathological  damage  after  drug  intervention. CONCLUSIONS  Citri  Grandis  Exocarpium  extract  improves
          gastric motility and protects gastric mucosa in the immature rats by regulating the concentration of gastric acid, pepsin activity, the
          levels of GAS, MTL and GIP, thus improving anorexia in immature rats.
