dc.description.abstractBulgarian rose damascena 오일은 항염, 항산화, 항균성을 가진 것으로 잘 알려져 있기 때문에, 이것이 항 진균성을 가지는지 확인하고자 가장 일반적인 기회주의적 곰팡이 병원체인 Candida 균으로 실험을 진행하였다. 먼저 디스크 확산 검사를 통해 Bulgarian rose damascena 오일이 Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli 등의 박테리아뿐 만 아니라 Candida albicans의 생장도 억제하는 것을 확인하였다. Candida albicans와 Candida glabrata에 대한 Bulgarian rose damascena 오일의 최소 생장 억제 농도와 최소 살균 농도는 0.25% 였다. 항 진균 효과가 있다고 잘 알려진 에센셜 오일들과 같은 실험 조건에서 비교했을 때, Bulgarian rose damascena 오일의 Candida albicans와 Candida glabrata에 대한 생장 억제 효과가 Origanum vulgare 에센셜 오일을 제외한 나머지 오일들에 비해 큰 것을 확인하였다. 또한 Bulgarian rose damascena 오일은 산성 환경에서 더 좋은 항 진균성을 보였으며, 산성 배양 배지에서 0.05%의 오일로 25-35%의 candida 균이 죽는 것을 확인하였다. 게다가 Bulgarian rose damascena 오일은 RPMI 배지에서 Candida albicans의 균사 형성을 억제하였다. 따라서 Bulgarian rose damascena 오일은 Candida 균에 대한 항 진균성을 가지며, 나아가 질염을 일으키는 병원성 진균에 대한 치료제로서 발전할 수 있는 가능성을 시사한다.;Since Bulgarian rose damascena oil is known to have anti-inflammatory, antioxidant, and antimicrobial properties, its antifungal activity against species of Candida, which are among the most common opportunistic fungal pathogens were investigated. Disk-diffusion assay revealed that Bulgarian rose damascena oil effectively inhibited the growth of Candida albicans along with various bacteria, including Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli. The minimum inhibitory and fungicidal concentrations against Candida albicans and Candida glabrata were all 0.25%. Various popular essential oils reported to have antifungal activity were tested and found that, under experimental conditions, Bulgarian rose damascena oil showed better inhibitory effects on Candida glabrata and Candida albicans than all but one of the tested oils; the exception was Origanum vulgare essential oil, which had better inhibitory effects. Interestingly, Bulgarian rose damascena oil showed better antifungal activity against Candida species at acidic pH and induced cell death of Candida species in culture medium, with cell death seen in 25 to 35% of cells exposed to 0.05% Bulgarian rose damascena oil. Furthermore, Bulgarian rose damascena oil inhibited the hyphal growth of Candida albicans cultured in RPMI medium. These findings collectively suggest that Bulgarian rose damascena oil has antifungal activity against Candida species, and thus could potentially be developed in novel therapies for vaginitis-causing pathogenic fungi.-
