概括
这项研究在口腔裂口的婴儿中发现HBD-3和HBD-4的水平较低,这表明慢性炎症. 免疫因子之间的相关性表明,在早期裂唇和 palatal 发育中,愈合和防御机制发生了改变.
科学领域:
- 免疫学 免疫学 免疫学
- 发展生物学 发展生物学
- 口腔和牙面部外科手术
背景情况:
- 唇裂 (CLP) 是一种常见的先天性缺陷.
- 局部组织防御因素对于免疫反应,炎症和CLP组织的愈合至关重要.
- 之前对这些因素的研究集中在年龄较大的儿童身上,在了解早期发育方面留下了一个差距.
研究的目的:
- 调查在早期牙形成前和期间患有CLP的婴儿中关键免疫和防御因子 (LL-37,CD-163,IL-10,HBD-2,HBD-3,HBD-4) 的分布.
- 在CLP早期发展的独特背景下分析这些因素之间的相关性.
- 提供关于裂组织早期免疫环境的见解.
主要方法:
- 分析了20年来经历了背皮整形手术的13名患者的口腔组织样本.
- 利用免疫组织化学和光显微镜进行可视化.
- 使用半定量评估和非参数统计分析来评估因素分布和相关性.
主要成果:
- 在结缔组织中观察到人类β-防御素3 (HBD-3) 和人类β-防御素4 (HBD-4) 的显著降低.
- 在人类β-防御素2 (HBD-2),HBD-3,HBD-4和LL-37之间发现了强烈,显著的相关性.
- 没有检测到Interleukin-10 (IL-10) 水平的显著变化,这表明潜在的抑制,而M2巨标记物 (CD-163) 存在.
结论:
- 缺乏HBD-3和HBD-4可能会在早期的CLP中促进慢性炎症.
- 观察到的相关性表明了上皮屏障的改变,增强了愈合和修改的抗菌防御.
- 这些发现突出了裂口发育过程中复杂的早期免疫场景,并为未来的治疗策略提供了目标.

Teeth
431
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Assessment of the Mouth
215
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Psychosexual Stages of Personality: Oral
758
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Oral Cavity
713
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
