UNLABELLED
Acute Otitis Externa is an inflammation of the outer auditory meatus, and according to popular saying, medicinal plant extracts can be used in its treatment.
AIM
to assess the in vitro antimicrobial activity of the following plants: Aleolanthus suaveolens; Caryophyllus aromaticus; Cymbopogon citratus; Matricaria chamomila; Pithecellobium avaremotemo; Plectranthus amboinicus and Ruta graveolens on the germs that cause otitis externa.
MATERIALS AND METHODS
the minimum inhibitory concentration of extracts and oils from these plants was obtained from otitis externa samples.
RESULTS
Staphylococcus aureus in 10 cultures, Pseudomonas aeruginosa in 8, Pseudomonas aeruginosa and Staphylococcus aureus together in 5 cultures and Candida albicans and Candida krusei in 4 cultures. P. aeruginosa was resistant to all oils and extracts tested; extracts from A. suaveolens, P. avaremotemo and R. graveolens were inactive; the essential oil from C. aromaticus and M. chamomila were active against 3 strains of S. aureus and the Candida strains; seven of the S. aureus strains were sensitive to the P. amboinicus extract; however, the oil was inactive against 4 S. aureus strains and the Candida strains were sensitive to the R. graveolens essential oil.
CONCLUSION
depending on the etiological agent, some plants presented satisfactory results, however we still need more detailed studies in order to better use these plants.
未标注
急性外耳道炎是外耳道的炎症，俗话说，药用植物提取物可用于治疗。
目的
评估以下植物对引起外耳道炎的病菌的体外抗菌活性：香花艾氏木；丁香；柠檬香茅；母菊花；猴耳环；延命草和芸香。
材料与方法
从外耳道炎样本中获取这些植物提取物和油的最低抑菌浓度。
结果
10份培养物中有金黄色葡萄球菌，8份中有铜绿假单胞菌，5份培养物中同时有铜绿假单胞菌和金黄色葡萄球菌，4份培养物中有白色念珠菌和克柔念珠菌。铜绿假单胞菌对所有测试的油和提取物均耐药；香花艾氏木、猴耳环和芸香的提取物无活性；丁香油和母菊花精油对3株金黄色葡萄球菌和念珠菌菌株有活性；7株金黄色葡萄球菌菌株对延命草提取物敏感；然而，该油对4株金黄色葡萄球菌菌株无活性，念珠菌菌株对芸香油敏感。
结论
根据病原体不同，一些植物呈现出了令人满意的结果，然而，为了更好地利用这些植物，我们仍需要更详细的研究。
