概括
毒素A型 (BoNT-A) 注射可以减少咬伤力. 注射更多的肌肉,包括中间状肌肉,会对肌功能产生更持久的影响.
科学领域:
- 牙科 牙科是指牙科的专业.
- 神经学 神经学
- 药理学 药理学是指药理学的学科.
背景情况:
- 毒素A型 (BoNT-A) 用于治疗各种影响肌肉的疾病.
- 了解BoNT-A对咬力的剂量依赖作用对于治疗应用至关重要.
研究的目的:
- 为了研究如何注射BoNT-A到不同的肌的组合会随着时间的推移影响咬力.
- 根据注射的数量和特定肌肉来确定减少咬伤力的持续时间.
主要方法:
- 35名男性参与者根据注射部位被分为三组:仅注射体 (M),注射体和体 (MT) 和注射体,体和中间体 (MTP).
- 在注射前和注射后最多六个月,使用牙科前级II系统测量咬力.
- 在不同注射组中分析了咬伤力的变化.
主要成果:
- 所有组都显示,在BoNT-A注射后,咬伤力初步减少.
- 单次注射的masseter (M) 和masseter-temporalis (MT) 导致暂时减少咬伤力,并在一个月内恢复.
- 涉及中枢状肌肉 (MTP组) 的注射显示出更显著和长时间的咬力下降,持续长达四个月.
结论:
- 用BoNT-A注射的肌的数量会影响咬力抑制的程度和持续时间.
- 多肌肉注射,特别是那些包括中介性骨的注射,可以更持久地抑制咬伤力.
- 需要进一步的临床研究来证实多肌肉BoNT-A注射对关节障碍和口腔 dystonia等疾病的治疗益处.

1.1K
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.

560
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
