| dc.description.abstract | The development of alternative therapeutic treatments based on the use of medicinal and aromatic plants, such as Juniper communis L., has aroused interest in the medical feld to fnd new alternatives to conventional therapeutic treatments, which have shown problems related to bacterial resistance, high costs, or sustainability in their production. The present work describes the use of hydrogels based on
sodium alginate and carboxymethyl cellulose, with combinations of juniperus leaves and berry extracts, in order to characterize their chemical characteristics, antibacterial activity, tissue adhesion test, cytotoxicity in the L929 cell line, and their efects on an in vivo model in mice to maximize the use of these materials in the healthcare feld. Overall, an adequate antibacterial potential against S. aureus, E. coli and P.
vulgaris was obtained with doses above 100 mg.mL−1 of hydrogels. Likewise, low cytotoxicity in hydrogels combined with extracts has been identifed according to the IC50 value at 17.32 µg.mL−1, compared to the higher cytotoxic activity expressed by the use of control hydrogels with a value at 11.05 µg.mL−1. Moreover, in general, the observed adhesion was high to diferent tissues, showing its adequate capacity to be used in diferent tissue typologies. Furthermore, the invivo results have not shown erythema, edema, or other complications related to the use of the proposed hydrogels. These results suggest the feasibility of using these hydrogels in biomedical applications given the observed safety. | tr |
