RESUMO
Objecttive To explore the effect of medical polyacrylamide hydrogel on the ultrastructure of human fibroblasts.Methods 22 hyperplastic fibropeplos around the medical polyacrylamide hydrogel in mammaries after augmentation mammoplasty by injection of medical polyacrylamide hydrogel were obtained by operations.The tissues were observed with the transmission electron microscope and at the same time photographs taken.Results Most of cell organoles dissolved and disappeared;Most of the cristaes and membranes of mitochondria coalesced or disappeared;rough endoplasmic reticulum expanded.Most of the cristaes and membranes coalesced or/and disappeared.The phenomenon of shed particle was observed in some of the rough endoplasmic reticulum.Conclusion The medical polyacrylamide hydrogel obviously injures the ultrastructures of human fibroblasts.
