title: Evaluation of anti-secretory and anti-ulcerogenic activities of avipattikar churna on the peptic ulcers in experimental rats.
abstract: BACKGROUND
  Avipattikar churna, a poly-herbal formulation, is one of the popular ayurvedic formulations which is used for peptic ulcer diseases but the scientific documentation with regards to its effect for the indication is lacking.
  
  
  OBJECTIVE
  This study was carried out to evaluate the anti-secretory and the anti-ulcerogenic activities of the churna and to compare its activity with that of ranitidine in a pyloric ligated model of rats.
  
  
  METHODS
  Four groups of rats with 6 animals in each served as the ulcer controls, churna low dose (500 mg/kg), churna high dose (750mg/kg) and ranitidine (25mg/kg). The control group rats received only vehicle (2% (v/v) gum acacia), while the rats of the other groups received the respective dose of the churna or ranitidine which was suspended in the vehicle. The treatments were given twice a day, orally, for two days. After 1 hour of the last dose, pyloric ligations were performed and the rats were sacrificed for evaluation after four hours of the ligations. The gastric contents were collected and its volume, pH and acidity were measured. The numbers of ulcers and their lengths were measured which were used to calculate the gastric irritancy index and the curative ratio. The histological examinations of the gastric tissues were also performed.
  
  
  RESULTS
  The churna, in both doses, significantly decreased the volumes of the gastric contents, the ulcer score, the length of the ulcer, the gastric irritancy index and pH increased as compared to those in the control group. The effects of the churna were comparable to that of ranitidine. The histopathological evaluation of the gastric tissue also supported the results.
  
  
  CONCLUSIONS
  Avipattikar churna has anti-secretory and anti-ulcerogenic effects which are comparable to those of ranitidine in peptic ulcer diseases.
