ABSTRACT
OBJECTIVE:
To observe the effect of pungent dispersion bitter purgation method (PDBPM) on the esophageal mucosal intercellular space of reflux esophagitis (RE) model rats.METHODS:
Totally 100 Wistar rats were randomly divided into the control group, the model group, the Western medicine group (WM), the Chinese medicine group (CM), 25 rats in each group. Rats in the control group only received switch operation. Rats in the rest three groups received modified partial cardia muscle incision combined pylorus ligation of external parts to prepare the RE rat model. Starting from the 3rd day after operation, WM mixture (Motilium 3. 2 mg/kg + Omeprazole Capsule 4.3 mg/kg + Hydrotalcite Tablet 161.4 mg/kg) was administered by gastrogavage to rats in the WM group. Rats in the CM group was administered by gastrogavage with Modified Banxia Xiexin Decoction (5.7 g/kg), 2.5 mL each time, twice daily for 14 consecutive days. Equal volume of normal saline was administered by gastrogavage to rats in the control group and the model group. On day 7 and 14, the lower esophagus pH value, general specimen of mucosa and histopathologic changes were observed. Intercellular spaces of esophageal epithelium were measured for a control study.RESULTS:
Compared with the same group at day 7, the lower esophagus pH value increased at day 14 (P < 0.01); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium also decreased at day 14 in the CM group and the WM group (P < 0.05). Compared with the control group at the same time point, the lower esophagus pH value decreased in the model group (P < 0.01). The naked eye integral of esophageal mucosa, and intercellular spaces of esophageal epithelium increased in the model group with increased intercellular spaces (P < 0.01). Compared with the model group at the same time point, the lower esophagus pH value increased and the naked eye integral of esophageal mucosa decreased in the CM group and the WM group at day 7 and 14 (P < 0.01). Intercellular spaces of esophageal epithelium of RE model rats at day 14 was lower in the CM group and the WM group than in the model group (P < 0.01). Compared with the WM group, the lower esophagus pH value decreased at day 7 in the CM group (P < 0.05); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium decreased at day 14 in the CM group (P < 0.05).CONCLUSIONS:
PDBPM had favorable treatment effect on RE model rats. The therapeutic effect was more obvious along with the therapeutic course went by. Its mechanism might be achieved through good repair effect on damaged mucosa, increasing the pressure of esophageal sphincter, and inhibiting gastric acid.
