Abstract:

Context: Peptic ulcers are a challenging problem. Silver nanoparticles (AgNPs) play a substantial role in bioactivity and have distinct characteristics. There are several biomedical uses for bioreduction nanotechnology. Historically, traditional healthcare has employed Juglans regia L. Aims: To evaluate how well fruit pellicle extract-derived bio-reduced silver nanoparticles (AgNP/FP) can treat peptic ulcers. Methods: Ultraviolet spectra, dynamic light scattering, transmittance electron microscopy, and Fourier transform infrared were used to characterize AgNPs and AgNP/FP. AgNPs and extracts were compared to omeprazole in ethanol-induced stomach ulcers in mice. Six groups of 36 mice were created at random. AgNPs were given orally to the experimental groups, using 300 mg/kg as a dose. The reference proton pump inhibitor, omeprazole, was employed as a control. Results: As evidenced by a falling ulcer index and an increase in the percentage of ulcer inhibition, bio-reduced AgNPs decreased the adverse effect of ethanolinduced stomach injury. Reduced mucosal damage and hemorrhagic lesions, necrobiotic alterations in the stomach epithelium, submucosal edema, and blood vessel congestion were all indicators of substantially reduced ethanol-induced gastric lesions and greater anti-inflammatory results. Conclusions: Fruit pellicle extract-derived bio-reduced silver nanoparticles have an efficacy similar to proton pump inhibitors like omeprazole and a lower incidence of possible side effects, making them a safe herbal therapy for ulcers.
