Food and Drug Administration. Benefits are believed to include continuous, sustained discharge of silver cations for broad spectrum antimicrobial safety; demonstration of quick bactericidal activity against a broad selection of pathogens in pharma codynamice in vitro model; no flaking or shedding of elemental silver; high versatility, allowing dressings to be used for multiple wound applications; no staining of individual, wound clinician or bed; and smoother skin software and greater patient ease and comfort.Univariate logistic-regression analysis demonstrated that failures were associated with a true number of factors, including age, the reason for limbal stem-cell deficiency, prior surgical procedures, the severity of damage, culturing and graft-transport complications, postoperative complications, and inflammation . On multivariate logistic-regression evaluation, failures were still significantly linked to the severity of harm and with culturing, graft-transport, and postoperative problems . Post hoc analyses showed no factor in the likelihood of success between eye that were also treated with keratoplasty and eyes that were not . Criteria for Graftable Limbal Cultures The common %age of clonogenic cells detected in cultures was similar for successful, partially successful, and failed transplants .
