概括

一种新型的酸 (HA) 水凝装载着曼戈斯坦尼 (MGTN) 为牙周病 (PD) 治疗提供了一种生物相容的替代方案. 这种MGTN-HA水凝显示出强大的抗菌活性,没有传统治疗的细胞毒性.

科学领域:

生物材料科学生物材料科学
牙周病学牙周病学
药物输送系统药物输送系统

背景情况:

牙周病 (PD) 治疗通常表现出抗菌疗效,但引起了关于口腔组织毒性的担忧.
对于预防和治疗PD而言,生物相容性抗菌剂的需求非常大.

研究的目的:

开发和评估一种化学修饰的氨酸 (HA) 水凝,其中包含曼哥斯坦尼 (MGTN),作为PD治疗的潜在较少毒性替代品.
评估MGTN载荷的HA水凝的结构性质,药物释放动力学和体外性能.

主要方法:

原生HA的化学修饰,使其能够自发地形成水凝.
在不同度的HA水凝中加入曼戈斯坦尼 (MGTN).
评估水凝特性:结构,胀,MGTN释放,质和降解.
使用3D工程的人类牙对Porphyromonas gingivalis的抗菌活性和生物相容性的评估.

主要成果:

修改后的HA水凝表现出稳定性和持续的MGTN释放超过7天.
载有MGTN的HA水凝表现出与商用0.2%的素 (CHX) 凝具有相似的抗菌活性.
与CHX凝的细胞毒性相反,MGTN-HA水凝证明与工程人类牙具有生物相容性.

结论:

开发的含有曼戈斯坦的氨酸凝可提供受控的MGTN释放.
这种MGTN-HA水凝是牙周病的高度生物相容性和有效的抗菌治疗选择.
它是传统治疗的有希望的替代品,减轻了人们对口腔组织毒性的担忧.

Hand hygiene

Hand hygiene

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.

Glycosaminoglycans

Glycosaminoglycans

Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.
