|September 27, 2024
概括
乙酸 (PA) 在烯酸树脂和合金上对多种生物膜表现出最强的抗菌膜作用. 乙烯基化 (CPC) 和N-乙半氨酸 (NAC) 显示了中间作用,没有任何药物完全消除了生物膜.
科学领域:
- 口腔微生物学和材料科学.
- 化学剂的抗菌疗效. 化学剂的抗菌疗效.
- 生物膜的形成和抑制.
背景情况:
- 牙假肢上的多种生物膜构成了重大的临床挑战.
- 热聚合烯酸树脂 (AR) 和- (Co-Cr) 合金是牙科器械的常见材料.
- 控制这些表面上的生物膜积累对于预防二次感染至关重要.
研究的目的:
- 评估 peracetic 酸 (PA), cetylpyridinium 化物 (CPC) 和 N-Acetylcysteine (NAC) 的抗菌膜疗效.
- 为了比较这些剂对Streptococcus mutans,Staphylococcus aureus,Candida albicans和Candida glabrata的多种生物膜的影响.
- 评估抗菌膜在烯酸树脂 (AR) 和- (Co-Cr) 合金表面上的活性.
主要方法:
- 在AR和Co-Cr标本上开发了多种生物膜.
- 标本被浸入含有PA (2.5 mg/mL),CPC (0.5 mg/mL) 或NAC (160 mg/mL) 的溶液中.
- 分析了生物膜活力 (CFU),代谢活性 (XTT),覆盖范围 (活/死),细胞外聚合物质 (EPS) 和形态. 统计分析包括ANOVA和Tukey/Dunn测试.
主要成果:
- 甲酸 (PA) 在AR和Co-Cr表面显著降低了微生物活力 (CFU) 和代谢活性 (XTT).
- N-乙半氨酸 (NAC) 有效地降低了细菌活力,但没有影响酵母活力或去除聚合生物膜.
- 化 (CPC) 显示了表面依赖的疗效,在AR上更有效,并且没有显著影响代谢活动或残留生物膜.
结论:
- 甲酸 (PA) 在测试剂中表现出最强的抗菌膜活性.
- CPC和NAC表明了中间的抗菌膜效应.
- 没有一个评估的解决方案完全消除了AR和Co-Cr合金表面的多种生物膜.

Drugs Used in Upper Respiratory Disorders: Overview
183
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

Hand hygiene
3.1K
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.
