    Membrana de cáscara de huevo para la curación de heridas superficiales en ratones
    (National Institute of Health, 2022) Noelia Mendoza; Georgina Chávez; Omar Araya
    Introduction: Eggshell membranes offer beneficial properties for tissue regeneration and their biomedical applications are important. Objective: To demonstrate the effectiveness of hen unfertilized eggshell membranes in the treatment of superficial open wounds in mice compared to the conventional procedure. Materials and methods: 15-mm linear wounds were made on the back of 10 male CF-1 mice. The mice were divided into four groups. One group did not receive any treatment and the other three were given conventional treatment, eggshell membranes dressing, and eggshell membranes powder. The evolution of the wounds was registered by photographs. We measured wounds length and healing time and calculated the length reduction rate and the percentage of healing. The healing percentages were analyzed by ANOVA with a post hoc Dunnett test (p<0.05). Results: The treatments with eggshell membranes and membrane powder had a woundlength reduction rate of 1.009 and 1.020 mm/day, greater than the conventional treatment, of 0.852 mm/day, and a healing time of 12 days, i.e., less than the 16-day conventional treatment. The statistical analysis showed significant differences between eggshell membrane treatments and the conventional treatment. Conclusions: Eggshell membrane dressing and eggshell membrane powder applied to open superficial wounds in mice were more effective than the conventional treatment in regenerating injured tissue in mice.
