长期口服K3酸盐给LG/J小鼠.
盘石化发生率和严重程度的评估.
对脊椎骨结构,膝盖化,血化学和运动的分析.
里埃变换红外光谱 (FTIR) 用于分析矿物成分.
在核脉 (NP) 和末板细胞中对内分泌区分的评估.

主要成果:

K3酸盐显著降低了椎间盘化的发生率.
没有观察到对脊椎骨结构,膝盖化,血化学或一般运动的不良影响.
接受治疗的小鼠表现出更强的握力.
FTIR分析证实K3酸盐没有改变化结节的矿物成分.
通过化Ca2+和受差异影响的细胞分化,K3酸盐减轻了化,减少了NP细胞中的过度缩性冠状细胞命运,但没有影响端板.

结论:

口服K3酸盐是一种有前途的系统性干预,用于年龄相关的椎间盘化.
治疗效果涉及Ca2+化和NP细胞分化的调制.
K3酸盐可以改善圆盘化,而不会损害骨的完整性或一般的身体功能.

Degenerative Disc Disease I: Introduction

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
