Objective:To prepare the argentation medical polypropylene mesh and detect it’s antibiosis-nature.Methods: Argentum was used as antibacterial agent to prepare the argentation medical polypropylene mesh with chemistry liquid phase the meshes with Rochelle salt as reducing agent.Antibiosis-nature of the meshes of argentation group(n=10) and control group (n=10)was quantitatively and qualitatively analyzed with slip diffusion method and soaking method.Results:For slip diffusion method(qualitation)

bacteriostasis-collares were not manifested and Staphylococcus aureuses apposition grew in meshwork of the control group(8mm×8mm×0.65mm)at 1d

3d and 7d;while that of the argentation group(8mm×8mm×0.65mm)were manifested at 1d、3d and 7d.The antibiosis-natures were significantly different between the two groups(P<0.05).The difference of different time points was not significant(P>0.05).For soaking method(quantitation)

the antibiosis-natures were significantly different between the two groups at 60min and 120min(P<0.05);the antibiosis-natures were not significantly different between the two groups at 240min(P>0.05).The difference of different time points was not signifieant(P>0.05).Conclusion:Argentation medical polypropylene mesh has antibiosis-nature

and the antibiosis-nature dose not change markedly with time as lapsed.
