| Research Abstract |
It has been known that silver and it's ions suppress the bacterial growth and works as an anti bacterial reagent. Recently some dressing materials and ointments contains silver ions, however, some reports indicate its toxicity for human cells and may induce the delay of wound healing. Fibroblast growth factor(bFGF) is one of the cytokine that stimulates cell migration and recombinant bFGF is used as an external medicine. The purpose of this study is to confirm if the silver ion act as cytotoxic, if the silver ion affect to the protein such as bFGF. We prepared 4 models for fibroblast culture ; model 1 : only medium with 1% CFS, model 2 : medium with bFGF and 1% CFS, model 3 : medium with bFGF, 1% CFS and silver ions, model 4 : medium with 1% CFS, bFGF which was incubated for 24 hours with silver ions, and silver ions. In this study, firstly, we confirmed that low concentration of silver ions doesn' t affect to cell growth and high concentration of silver ions does. Second, Second, bFGF mitigate the cytotoxic effect of silver ion. Third, the silver ion directly interact with bFGF and interacted bFGF became more harmful to cells.
