anti-anxiety and antioxidant properties of the zinc nanoparticles green-formulated by an ethnomedicinal plant in the in vivo condition

Objectives: one of the application areas of nanobiotechnology is the use of silver nanoparticles (nanosilver particles) for a new solution in medical treatments. in the present study, the researchers investigate the effect of nano silver particles of the aqueous extract of artemisia aucheri on skin wound healing among male rats.material and methods: after creating wounds in 48 rats, they were randomly divided into 6 groups. treated with 0.2% agnps ointment, 0.2% agso4 ointment,   0.2% a. aucheri  ointment, 3% tetracycline ointment, eucerin basal ointment, and untreated control group. the tested groups were treated for ten days.results: treatment with agnps ointment significantly increased the amount of vascular contraction, hexose amine and hydroxyproline, and fibrocyte and fibrocyte to fibroblast ratio. also, in the mentioned group, the wound area and the total number of cells, neutrophils and lymphocytes decreased significantly compared to other groups. conclusion: the nano silver particles of the aqueous extract of a. aucheri accelerate the healing process of skin wounds and reduce the time required for complete wound healing.
