1In vitro effects of Salvia officinalis L.essential oil on Candida albicans显示文摘Objective:To determine the anticandidal activities of Salvia officinalis L.(S.officinalis)essential oil against Candida albicans(C.albicans)and the inhibitory effects on the adhesion of C.albicans to polymethyl methacrylate(PMMA)resin surface.Methods:Disc diffusion method was first used to test the anticandidal activities of the S.officinalis L.essential oil against the reference strain(ATCC 90028)and 2 clinical strains of C.albicans.Then the minimal inhibitory concentration(MIC)and minimal lethal concentration(MLX)were determined by modified membrane method.The adhesion of C.albicans to PMMA resin surface was assessed after immersion with S.officinalis L.essential oil at various concentrations of 1XMIC.0.5XMIC and 0.25XMIC at room temperature for30 min.One-way ANOVA was used to compare the Candida cell adhesion with the pretreatment agents and Tukey's test was used for multiple comparisons.Results:5.officinalis L.essential oil exhibited anticandidal activity against all strains of C.albicans with inhibition zone ranging from 40.5 mm to 19.5 mm.The MIC and MLC of the oil were determined as 2.780 g/L against all test strains.According to the effects on C.albicans adhesion to PMMA resin surface,it was found that immersion in the essential oil at concentrations of 1XMIC(2.780 g/L).0.5XMIC(1.390 g/L)and0.25XMIC(0.695 g/L)for 30 min significantly reduced the adhesion of all 3 test strains to PMMA resin surface in a dose dependent manner(P<0.05).Conclusions:S.officinalis L.essential oil exhibited anticandidal activities against C.albicans and had inhibitory effects on the adhesion of the cells to PMMA resin surface.With further testing and development,S.officinalis essential oil may be used as an antifungal denture cleanser to prevent candidal adhesion and thus reduce the risk of candida-associated denture stomatitis.Tularat Sookto Theerathavaj Srithavaj Sroisiri Thaweboon Boonyanit Thaweboon Binit Shrestha 2013Asian Pacific Journal of Tropical Biomedicine2013,3,5:2
2In vitro antimicrobial effects of grape seed extract on peri-implantitis microflora in craniofacial implants显示文摘Objective:To determine the antimicrobial effects of grape seed on peri-implantitis microflora.Methods:The grape seed extract was tested against peri-implantitis microflora most commonly found in craniofacial implants including reference strains of Staphylococcus aureus(S.aureus),Escherichia coli(E.coli),Candida albicans(C.albicans)and clinical strains of S.aureus,Klebsiella pneumonia(K.pneumonia)and Candida parapsilosis(C.parapsilosis)by disk diffusion test.Minimum inhibitory concentrations(MIC)and minimum cidal concentrations(MCC)were determined using modified agar dilution millpore method.The extract was further combined with polyethylene glycol and propylene glycol,and was tested for antimicrobial effects.Results:Grape seed extract showed positive inhibitory effects with S.aureus at MIC of 0.625 mg/mL and MCC of1.25 mg/mL respectively.However the extracts showed minimal or no reactivity against strains of E.coli,K.pneumonia,C.parapsilosis and C.albicans.The use of grape seed extract in combination with polyethylene glycol and propylene glycol also showed dose dependent inhibitory effect on S.aureus.Conclusions:The results of the study showed that grape seed has potential antimicrobial effects which can be further studied and developed to be used in the treatment of infected skinabutment interface of craniofacial implants.Binit Shrestha M.L.Srithavaj Theerathavaj Sroisiri Thaweboon Boonyanit Thaweboon 2012Asian Pacific Journal of Tropical Biomedicine2012,2,10:1
