Abstract:
Background: The annual incidence of peptic ulcer disease is estimated to be four
million cases worldwide, with an average lifetime risk of 7.5% in individuals of all ages. Polymer
nanocomposites have novel prospects in the field of modern medicine.
Objective: The present research endeavors to assess the therapeutic efficacy of nanoparticles
composed of silver/chitosan, silver/saponin, and chitosan/saponin against gastric ulcers induced
by ethanol in Wistar rats.
Methods: Forty-eight rats were randomly split into eight groups of the same size. Oral ethanol
(5 ml/kg of body weight) was given to all rat groups except the control one for 1 hour before
treatment. Control and ulcer groups of rats were given distilled water orally. The rats in the other
groups were given orally 1/10 LD50 of each treatment as follows: AgNPs, chitosan NPs, Saponin,
AgNPs-Chitosan NPs, AgNP-Saponin, and chitosan-Saponin NPs.
Results: NP-treated groups showed a significant increase in the gastric juice pH, glutathione
reduced, catalase, and nitric oxide while gastric juice volume, ulcer index, and malondialdehyde
levels decreased compared with the ulcer group. Histopathological investigation of stomach
showed improvement in NPs groups specially in the chitosan-Saponin NPs group.
Conclusion: The current study revealed that silver-chitosan, silver-saponin and chitosansaponin
nanocomposites effectively treat gastric ulcers. Chitosan-Saponin nanoparticles showed
high therapeutic effectiveness against gastric ulcer in rats.
