概括
直接激光光生物调节 (PBM) 有效地减少了小神经纤维引起的急性疼痛. 这种非成性治疗选择性地向C和Aδ纤维,而不影响运动功能,提供了一个有希望的缓解疼痛的替代方案.
科学领域:
- 神经科学是一个神经科学.
- 疼痛研究 疼痛研究
- 生物医学工程 生物医学工程
背景情况:
- 药理性疼痛治疗有其局限性,包括缺乏特异性和副作用,如成和超痛症.
- 之前的研究表明,外围神经的直接光生物调制 (PBM) 可以减少慢性疼痛过敏,但不能减少机械敏感性.
- 对急性疼痛模型的混合神经直接激光应用此前没有进行过研究.
研究的目的:
- 为了研究直接激光照射对混合神经 (脊髓神经) 的影响,在老鼠的急性痛感疼痛模型中.
- 为了评估激光照射到坐骨神经是否会影响运动功能.
- 评估直接PBM作为一种潜在的非药物治疗疼痛的潜在非药物治疗方法,针对直径小的纤维.
主要方法:
- 直接激光照射 (808nm,60mW,4分钟) 应用于鼠患患有素诱导的急性疼痛的坐骨神经.
- 在两周内测量了机械和热过敏度.
- 通过在激光照射后测量胃半肌肉力量生成来评估运动功能.
主要成果:
- 直接PBM显著降低了素诱导的机械和热过敏症,分别高达70%和56.2%.
- 观察到的疼痛减轻是显著的 (p < 0.05),主要归因于抑制C和Aδ纤维活性.
- 在辐射后120分钟内,没有观察到胃半腹肌力量生成的显著变化,这表明运动功能得到保护.
结论:
- 坐骨神经的直接光生物调制 (PBM) 有效地减少通过小直径纤维介导的急性感知性疼痛.
- 这种方法可以选择性地抑制C和Aδ纤维的传输,同时保持运动神经活动.
- 直接PBM显示承诺作为一个有针对性的,非成的治疗方法,用于与小直径纤维活动相关的疼痛条件.

Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
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.
