概括
橄叶提取物 (OLE) 以剂量取决的方式对口服的Candida物种表现出显著的抗真菌活性. 然而,当与标准抗真菌疗法相结合时,OLE没有显示出协同效应.
科学领域:
- 菌类学 菌类学是指菌类学.
- 药理学 药理学是指药理学的学科.
- 自然产品 自然产品
背景情况:
- 口腔角膜炎是一种常见的真菌感染,通常是由*Candida*物种引起的.
- 标准的抗真菌疗法可能因耐药性和副作用而受到限制.
- 像橄叶提取物 (OLE) 这样的天然化合物正在研究它们的抗菌特性.
研究的目的:
- 为了评估OLE的抗真菌活性与临床口服*Candida*分离物相比.
- 为了确定OLE是否增强标准抗真菌药物 (miconazole和nystatin) 的疗效.
主要方法:
- 测试了60种 *Candida* 种类 (*C. albicans*, *C. krusei*, *C. glabrata*, *C. tropicalis*) 的临床分离物.
- 使用磁盘扩散方法评估了对四种OLE度和与miconazole/nystatin组合的抗真菌敏感性.
主要成果:

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
