Cultured human keratinocytes were exposed to liposomally encapsulated silver sulfadiazine, free silver sulfadiazine, silver sulfadiazine cream, and a corresponding vehicle for 5 min to 24 h. Phagocytosis of intact liposomes by keratinocytes was demonstrated in vitro by combined X-ray microanalysis and electron microscopy. Silver as an active part of the antimicrobial served as an electron-dense marker.
将培养的人角质形成细胞暴露于脂质体包裹的磺胺嘧啶银、游离磺胺嘧啶银、磺胺嘧啶银乳膏以及相应的赋形剂中5分钟至24小时。通过结合X射线微量分析和电子显微镜在体外证实了角质形成细胞对完整脂质体的吞噬作用。作为抗菌活性成分的银充当电子致密标记物。
